    1527031 Moulding impregnated porous substrates J ROTH 6 Jan 1976 [5 Feb 1975] 00296/76 Headings B5A and B5N In order to produce a panel, e.g. car roof, padding having regions of different rigidity, a foam sheet 1, is impregnated at selected regions with catalysed resins mixtures, each resin mixture giving rise to a polyurethane polymer of different rigidity and placed in a mould 3, 4 to be shaped. Three resin mixtures may be employed giving rise to flexible, semirigid and rigid polyurethanes. The resin mixtures may be applied by spraying, dipping or roller coating with excess material being expelled by passage through rollers. The panel may be provided with a textile fabric or PVC covering 2 and a backing support of paper or cardboard on the face 1<SP>1</SP>. The covering and/or backing may be applied in or prior to the entry in the mould. Two or more superimposed substrates (see Fig. 4, not shown) may be moulded together with or without inserts (8), e.g. fasteners at point of use and/or textile reinforcement (7) therebetween.

    (54) METHOD FOR OBTAINING A PANEL
    L
    The invention relates to the plastics industry, in particular to the development of a method for producing a panel.
    A known method of producing a panel includes duplicating a porous layer with a reinforcing and / or finishing substrate during thermal pressing in the form of 1.
    The known method does not provide. P (for the panel at the same thickness with different flexibility in area.
    The purpose of the invention consists in obtaining a panel with the same thickness and different nesting area.
    The goal is achieved by the fact that in the method of obtaining the panel, which includes duplication of the porous layer with a reinforcing and / or finishing substrate during thermal pressing in the form, the porous layer, prior to duplication, is fed with various polyester alloys in different parts of the area, and then held to partially cure the impregnating compositions until sticky.
    Example. For the manufacture of panets, a flexible or rigid layer of polyurethane foam (preferably flexible) with a low density, for example, 20 g / dm, is used.
    It is also possible to use a layer made of another porous material, such as polyvinyl chloride, or a layer of natural or man-made fibers, such as horsehair or fiberglass.
    The spinning composition consists of a mixture of a polyalcohol, isocyanate, a catalyst, such as tin octoate, and of a sufficient amount of trichlorofluoromethane (or methylene chloride, or a similar substance), which serves to dilute the mixture and bring it up to the required viscosity for complete application.

    100 parts by weight are used for the formulation. polyalcohol type triol or tetraol, 85 weight.h. methylphenyl diisocyanate isocyanate of tnpa, 0.05-0.1 weight.h. catalyst, which may be an organic tin salt, such as tin octoate, tin naphthenate, lead naphthenate, 5-20 all, trichlorfluoromethane (Frönen) or methylene chloride. ,: 7 Production of various flexures: bb1 or stiffness in certain places of the section of the panel is achieved by using a different type of polysport in the impregnating composition. Make the panel as follows. A support of polyurethane foam is cut into plates of the desired size and moistened on both sides in places that must be opened with flexibility corresponding to the impregnating mixture. Thus, in the zone where the panel should remain flexible, use an impregnating mixture containing a flexible polyalcohol. In the area where the panel should be polzakestku, semi-rigid polyalcohol is used, and in the area that should be rigid, anchoring a mixture of hard polysport. This support is moistened with this mixture so that in the presence of a catalyst and trichlorofluoromethane, the poly alcohol will react with the iso cyanate. After the operation of wetting (impregnating the support) and Bringing the impregnating composition (due to the reaction of polyspirta and diisocyanate) to an adhesive state, the support is placed in a mold that is pre-coated with facing or finishing material, and the final thermal pressing is carried out (until the final curing of the composition) . . According to the second variant, the support is placed in the base material before it is placed in the mold. This option eliminates the formation of unnecessary skla, sock on the cladding material. After the mold is closed, the curing (polymerization {w) of the penetrating composition is carried out either at ambient temperature or at heating, which accelerates the process. It is also possible to manufacture the panel without finishing material, in this case the inner surface of the mold is coated with grease to facilitate removal from the panel. In the third embodiment, the panels are made of two foam foams, covered with an impregnating compound and rolled together, with the spacer between the foam layers (textile fabric or cardboard sheet). In addition, brackets or other devices that are used to fasten the panel (in the process of using it) are sometimes placed between the two foam layers. The proposed method produces panels with the same thickness but different flexibility in area, which is very important for many polymeric materials. Formula of the invention The method of obtaining the panel, which includes duplication of the porous layer with a reinforcing and / or finishing the substrate during thermal pressing in the form, and with the fact that, to obtain a panel with the same thickness and different flexibility in area, porous Before duplication, the layer is coated with polyurethane compositions based on polyalcoats of various hardness in various areas of the area, and then held to partially cure the impregnating composites to maintain tackiness.
