A reactive polyvinyl chloride self-adhesive waterproof membrane
A technology of self-adhesive waterproof roll material and polyvinyl chloride, which is applied in the direction of chemical instruments and methods, layered products, synthetic resin layered products, etc., can solve the problem that the surface is not easy to bond, self-adhesive does not match, and no polymer is used. Coil surface treatment measures and other issues, to achieve the effect of simple glue mixing process and reduced energy consumption

preparation example Construction
[0025] The preparation method of functionalized EPDM rubber is not particularly limited, and the preparation method can be listed as follows: (1) dissolving non-vulcanized EPDM rubber in toluene; (2) heating the dissolved solution to 50°C- 100°C, and add benzoyl peroxide to dissolve; (3) Add olefinic monomers containing ethylenic double bonds and epoxy groups to the EPDM rubber solution, fully react, and separate to obtain functionalization EPDM rubber.
[0026] The self-adhesive layer contains functionalized EPDM rubber, heavy traffic asphalt, tackifier, thiuram accelerator, aluminum trichloride, tertiary amine accelerator, cerium ammonium nitrate, antioxidant, ultraviolet absorber agent, calcium silicate and silicon dioxide, when the self-adhesive layer is 100 parts by mass: functionalized EPDM rubber is 10-70 parts by mass; heavy traffic asphalt is 10-70 parts by mass; tackifier is 5-70 parts by mass 20 parts by mass; 0.1-5 parts by mass of thiuram accelerators; 0.1-1 part...
Embodiment 1
[0047] The reactive polyvinyl chloride self-adhesive waterproof membrane includes a polyvinyl chloride waterproof base layer, a self-adhesive layer and an isolation layer. On the outer surface of the two self-adhesive layers, the release film is a commercial PET release film.
[0048] The reactive polyvinyl chloride self-adhesive waterproof membrane includes a polyvinyl chloride waterproof base layer, a reinforcement layer, a self-adhesive layer and an isolation layer. The two reinforcement layers are respectively compounded on the upper and lower surfaces of the PVC waterproof base layer. The adhesive layer is respectively compounded on the upper and lower surfaces of the two reinforcement layers, and the two isolation layers are respectively compounded on the outer surfaces of the two self-adhesive layers. The isolation film is a commercial PET isolation film, and the reinforcement layer is a commercial glass fiber mesh cloth.

Embodiment 2
[0052] The functionalized EPDM rubber in the self-adhesive layer was changed from 30wt% to 25wt%, and the heavy traffic asphalt was changed from 40wt% to 45wt%, and the others were the same as in Example 1.
