    专利说明:

    The invention relates to construction, namely to sheet multilayer waterproofing materials.
    The purpose of the invention is the improvement of physical and mechanical properties. j
    The drawing shows the proposed material.
    A three-layer waterproofing material contains outer layers 1 and 2 of a thickness of 0.75 mm from an elastic plastic based on a triple polymer containing the following components, May. %:
    Ethylene 65-67
    Propylene 2J 15
    Ethylidene Norbornene 6-8
    In this case, the elastomeric plastic, in addition to the ternary polymer of the specified composition, contained in the plastic in an amount of 35-46 wt.%, Contains the following components, Filler Soot Aliphatic and / or naphthenic may.%:
    26-31 '19 -25 vulcanizing oils 7-12
    The stabilizer and antioxidant 0.1-1.0.
    Lubricant, e.g. metal soap 0.1-5.0
    In addition, it may additionally contain, in an amount of 1.82.3 wt.%, Processability improvers, for example montanoic acid esters, hydrogenated hydrocarbon resins.
    Said elastomeric plastic is partially crystalline and has a heat of fusion of DN 5 , determined using a differential scanning calorimeter, of at least 10 J / g.
    The filler used is preferably silica, i.e. a mixture of silicic anhydride and kaolinite, and the grain size should be less than 20 mmkm, and 40% of the grain should have a particle size of less than 2 mmkm · In addition, 2/3 of the volume of silica can be replaced by other fine-grained fillers, such as chalk, kaolin, talc, heavy spar and / or fiberglass.
    Between layers 1 and 2 there is a reinforcement 3 made of fiberglass, and there is no reinforcement around the perimeter of the material. Fiberglass reinforcement has a mass of 30 g / cm 2 and the distance between the warp and weft threads is 2 mm.
    Example. 40 parts by weight ternary polymer of ethylene, propylene and diene with 67 wt.% ethylene, 27 wt.% propylene and 6 wt.% ethylidene norbornene (dnd 14 J / g) are mixed first with 22.5 wt. semi-active soot and then with 27 wt.h. silica, 8 parts by weight vulcanizing oil, 2 parts by weight hydrocarbon resin, 0.3 parts by weight calcium soap and 0.2 wt.h. antioxidant.
    The resulting mixture was transferred to 0.75 mm thick calendaring films. Then the two films are connected in a gap formed by two rollers, and a glass fabric weighing 30 g / m 2 having a distance between the warp and weft threads of 2 mm is introduced between the films. The connection of the layers is carried out with a pressure of 5 bar.
    The resulting three-layer waterproofing material is again subjected to a pressure of 6 bar. After cooling, powder is applied to the surface of the material to prevent bonding.
