    The invention relates to bitumen-containing PVC insulating sheets composed of the following layers: a) a 0.4-1.2 mm thick compact PVC foil optionally containing bitumen, b) a 0.4-2 mm thick closed-cell PVC foam layer optionally containing bitumen, c) a 0.1-1 mm thick layer for adhesion and assembling, and d) a separating layer ensuring the unwinding of the sheet. These sheets can be applied with excellent results to insulate bridges, runway panels and other structures against water and humidity.

    专利说明:

    The invention relates to an insulation material, in particular a bitumen-containing polyvinyl chloride, which is advantageous for the insulation of bridges, buildings and other construction objects.
    The purpose of the invention is to increase the wear resistance, durability and quality of insulation.
    The insulation board contains a substrate of a mixture of polyvinyl chloride with bitumen, 0.4–1.2 mm thick, the first adhesive layer of bitumen-containing polymer. 0.4–2.0 mm thick, and the second adhesive layer of bitumen, a polymeric binder , filler and plasticizer with a thickness of 0.1-1.0 mm.
    The polymer in the first adhesive layer is foamed polyvinyl chloride with a closed cellular structure. This layer provides the damping of perpendicular force effects such as compression or push.
    The second adhesive layer applied on the first one serves for gluing the insulating material onto the insulated surface and ensures complete tightness at the places of overlap. The second adhesive layer additionally contains a plasticizer and, as a polymeric binder, at least one product from the group: conifer resin , polybutene, copolymer of butadiene with styrene and / or attack tonic polypropylene, in the following ratio of components, wt.%: Bitumen 63-70

    As synthetic rubber, which improves the elasticity and insulating properties of the second adhesive layer (for example, resistance to salt and water), polymers are used that are not high, are bilded from bitumen and form a homogeneous system with it. Preferred are butadiene-styrene copolymers with a butadiene content of 60-75% by weight. The copolymers have a density of 0.9–1.0, a tensile strength of 1800–2600 N / cm, and an expansion at break of 500–1000%. Atactic polypropylene with a m.p. 130-175 ° С, density 0.8-0.9 and penetration 15-30.
    Dioctyl phthalate is used as a plasticizer, which has a viscosity of 5-50 cST at 20 ° C, a geological point is lower, and a flash point is higher than 150 ° C.
    Talc or chalk is used as a filler.

    The table shows the composition of the insulation plate according to examples.
    The insulation board is made as follows.
    Having a dense polyvinyl chloride film as a surface layer, the substrate is made of plastisol in one working operation. An infinite steel tape serves as the basis for the manufacturing process, and two paste mechanisms equipped with rubber rollers are used for the deposition. The plastisol components are homogenized in a planetary mixer.
    For the manufacture of the second adhesive layer, the components are metered one by one into the molten bitumen heated to 150-170 ° C, with the plasticizer being added first. The mixture is then homogenized for another 3-4 hours.
    The mass thus prepared is applied to the first layer by means of
    Resistance to low temperatures, ° C Water absorption,% The use of an insulating slab can reduce perpendicular impact shocks, vibrations and compressive forces and slow down or repair premature aging of the bridge bodies of roads, structures and other goods.
