    CAST FLOOR AND METHOD FOR APPLYING
    CAST FLOOR
    This invention relates to a polyurethane casting floor comprising pigments. This invention also relates to a method for applying a polyurethane casting floor to a surface, the method comprising the following steps of: providing different components of the casting floor; • mixing the various components; • pouring the mixed components onto the surface.
    Different types of cast floors are possible. A polyurethane screed floor is one of these types. A polyurethane screed floor has several advantages. This way it is easy to clean, it is slightly elastic so that it does not crack and can also be applied on less stable surfaces, it can be used in combination with underfloor heating and has a sound-absorbing effect. A drawback with the existing polyurethane cast floors is that certain colors or uniform color shades are difficult to obtain.
    For example, it is not easy to obtain a polyurethane screed floor with the view / drawing of a concrete floor or a view / drawing that is comparable to the view / drawing of a concrete floor. Today to obtain this view / drawing, two polyurethane compositions of different colors are taken and applied to a substrate. The color of such a polyurethane composition can be any type of RAL color (Reichs Ausschuss fur Lieferbedingungen) or NCS color (Natural Color System). These two polyurethane compositions are then cast together and then slightly stirred to weave the two colors together. Then these stirred compositions are poured out and these compositions are spread out over the surface. In this way a screed floor is obtained with patterns, giving the screed floor a more lively appearance. However, the disadvantage here is that the appearance of such a screed floor appears rather artificial and that it is cumbersome to install such screed floor. It also requires a certain expertise to install such a screed floor. With a lightly interwoven two-color polyurethane cast floor, it is particularly difficult to repeat the patterns. These two polyurethane compositions could in principle each also be applied separately to two different surfaces, so as to obtain two polyurethane cast floors with one uniform color each.
    It is therefore an object of the invention to develop a polyurethane casting floor whose appearance is comparable to that of a concrete floor and where the view is experienced as more natural. For example, it is desirable that the wing / clouds / patterns / drawings of the screed floor appear repetitive to a greater extent and do not look artificial. It is also an object of the invention to develop a method for applying a polyurethane poured floor with the appearance of a concrete floor, wherein this method is easy to carry out and can also be carried out by persons who are less experienced or not experienced.
    This object is achieved by providing a polyurethane casting floor comprising pigments, the pigments comprising aluminum and / or mother-of-pearl pigments. Additionally, the pigments may also include NCS and / or RAL pigments. The pigments containing aluminum and / or mother-of-pearl ensure that the cast floor obtains a view that is comparable to that of a concrete floor. The pigments containing aluminum and / or mother-of-pearl ensure that the cast floor has certain drawings / clouds / patterns that are similar to the drawings / clouds / patterns of a concrete floor. The appearance of the cast floor is experienced as natural here. This cast floor therefore has a pleasant and lively view.
    The casting floor preferably comprises a polyurethane resin and a hardener. The casting floor is then a so-called two-component casting floor. The casting floor is permanently elastic, dust-free and easy to clean.
    Further preferably, the polyurethane resin is aliphatic polyurethane resin. This makes the cast floor colorfast. Even under the influence of UV light, this cast floor will hardly discolor.
    In a very preferred embodiment, the casting floor comprises fillers. These fillers are capable of temporarily retaining the aluminum and / or mother-of-pearl pigments during the application of the casting floor, so that these pigments after a certain time become entangled in certain places to form the said drawings / clouds / patterns.
    The fillers preferably comprise quartz and / or quartz flour. Quartz and / or quartz flours ensure that the appearance of the screed floor with drawings / clouds / patterns is experienced as more natural.
    However, the fillers may also comprise glass beads. For example, they may comprise glass beads and not quartz and / or quartz flour or they may include both glass beads and quartz and / or quartz flour.
    Said fillers preferably make up 7 to 30% by weight of the casting floor. There are sufficient fillers here to temporarily hold the aluminum and / or mother-of-pearl pigments during the application of the casting floor so that good-looking drawings / clouds / patterns are created and a casting floor with the appearance of a concrete floor is obtained. There are also not too many present so that the screed floor retains the positive properties of a polyurethane screed floor being, among other things, seamlessness, good flow properties, self-leveling properties during the application of the screed floor, etc.
    Also preferably, the ratio of the weight of the fillers to the sum of the weight of the polyurethane resin and the curing agent, lying between 0.06 and 0.45, is even more preferably between 0.3 and 0.35.
    In a preferred embodiment, the aluminum and / or mother-of-pearl-containing pigments make up 0.05 to 0.35% by weight of the casting floor, even more preferably between 0.12 and 0.17. There are sufficient aluminum and / or mother-of-pearl pigments present here, but not too much either, so that the screed floor has the required amount of drawings / clouds / patterns. The amount of drawings / clouds / patterns here corresponds to the amount of drawings / clouds / patterns that a concrete floor has.
    Preferably, the ratio of the weight of the aluminum and / or pearlescent pigments to the weight of the fillers is between 0.0015 and 0.050, even more preferably between 0.005 and 0.006. Here the ratio of aluminum and / or mother-of-pearl pigments and fillers is good so that, during the application of the casting floor, the aluminum and / or mother-of-pearl pigments are retained by the fillers for the necessary time and so that the drawings / clouds / patterns of the match the screed floor as much as possible with the drawings / clouds / patterns of a real concrete floor.
    This object is also achieved by providing a method for applying a polyurethane casting floor to a surface, the method comprising the following steps: • providing different components of the casting floor; • mixing the various components; • pouring the mixed components onto the surface; wherein aluminum and / or mother-of-pearl pigments are provided and added to at least one of the components, prior to pouring of the mixed components.
    By adding aluminum and / or mother-of-pearl-containing pigments to at least one of the components prior to casting, a cast floor with a natural appearance is obtained, the appearance corresponding to the appearance of a concrete floor. These aluminum and / or mother-of-pearl pigments will in fact ensure that the cast floor comprises drawings / clouds / patterns that correspond to the drawings / clouds / patterns of a concrete floor. Here the drawings / clouds / patterns arise automatically during the curing process of the mixed components. With the aid of this method, a polyurethane floor as described above can be obtained.
    In a preferred embodiment, the components comprise a polyurethane resin and a hardener, wherein prior to mixing the components, the aluminum and / or pearlescent pigments are added to the polyurethane resin. This polyurethane resin may already comprise RAL or NCS pigments per se. By adding the aluminum and / or mother-of-pearl pigments to the polyurethane resin, good-looking drawings / clouds / patterns are obtained.
    The components preferably comprise a filler which is provided for temporarily retaining the aluminum and / or mother-of-pearl pigments during the application of the casting floor. This filler then comprises one or more fillers. This filler ensures that the aluminum and / or mother-of-pearl pigments are temporarily retained during the application of the casting floor. This causes the aluminum and / or mother-of-pearl pigments to stick together at the appropriate time, for example at the level of irregularities of the surface on which the casting floor is applied, so as to form the said drawings / clouds / patterns. By temporarily holding the aluminum and / or mother-of-pearl-containing pigments, it is also avoided that the casting floor has a sensitive surface.
    Even more preferably, the filler comprises quartz and / or quartz flour and / or glass beads. Quartz and / or quartz flour and / or glass beads are very well capable of temporarily retaining the aluminum and / or mother-of-pearl pigments. Moreover, they do not negatively influence the appearance of the cast floor.
    In a preferred embodiment, the polyurethane resin is first mixed with the hardener, after which the filler is added to the mixed polyurethane resin and hardener and the whole is mixed. By first mixing the polyurethane resin with the hardener, the resin will harden well later after casting. By mixing the filler with the mixed polyurethane resin and hardener to, for example, a homogeneous mass, the aluminum and / or pearlescent pigments, which are preferably added to the polyurethane resin before any mixing takes place, come into good contact with the filler. The filler is thus able to temporarily retain the aluminum and / or pearlescent pigments.
    In a very preferred embodiment the applied polyurethane casting floor is a polyurethane casting floor as discussed above.
    This invention will now be further elucidated with reference to the following detailed description of a preferred embodiment of a polyurethane casting floor and a method according to the present invention. The purpose of this description is to give only illustrative examples and to indicate further advantages and details of this polyurethane casting floor and method, and can therefore in no way be interpreted as a limitation of the scope of the invention or of the patent rights claimed in the claims. .
    The polyurethane screed floor, which is applied to a surface, is obtained by mixing different components together and then pouring them on the surface.
    The various components include an aliphatic polyurethane resin, a hardener, aluminum pigments and a filler. The filler comprises the following fillers: quartz, quartz flour and glass beads. The polyurethane resin comprises NCS and / or RAL pigments. For 25 kg of polyurethane resin and hardener together, approximately 8 kg of filler is provided and approximately 45 g of aluminum pigments.
    The method of applying this casting floor comprises the following steps: 1) Adding the aluminum pigments to the polyurethane resin; 2) Adding the hardener to the polyurethane resin; 3) Mixing the hardener and the polyurethane resin for two minutes; 4) Adding the filler to the mixed hardener and polyurethane resin; 5) Mixing the filler, the curing agent and the polyurethane resin into a homogeneous mass; 6) Pouring the mixed components onto the surface and spreading them out; 7) Flowing out and drying the screed floor.
    The filler temporarily holds the aluminum pigments so that the aluminum pigments do not immediately migrate upwards during the pouring and pouring step. After a certain time, the aluminum pigments will stick together at, among other things, unevenness of the surface, causing them to form clouds / patterns / drawings. These shaped clouds / patterns / drawings are very similar to the clouds / patterns / drawings that a cast concrete floor displays, giving the polyurethane casting floor the appearance of a real concrete floor. The appearance of this cast floor is therefore experienced as natural.
    The obtained polyurethane screed floor is here a screed floor comprising polyurethane resin, aluminum pigments, NCS and / or RAL pigments, quartz, quartz flours, glass beads and a hardener. The fillers here make up +/- 24% by weight of the casting floor. The ratio of the weight of the fillers to the sum of the weight of the polyurethane resin and the curing agent is substantially 0.32. The aluminum pigments make up +/- 0.14% by weight of the casting floor. The ratio of the weight of the aluminum pigments to the weight of the fillers is between 0.005 and 0.006.
