[0026] 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.
[0027] 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
[0048] The reactive polymer self-adhesive waterproof membrane includes a polyolefin waterproof base layer, a self-adhesive layer and an isolation layer. Two layers of self-adhesive layers are respectively compounded on the upper and lower surfaces of the polyolefin waterproof base layer. On the outer surface of the self-adhesive layer, the release film is a commercial PET release film.
[0049] The reactive polymer self-adhesive waterproof membrane includes a polyolefin waterproof base layer, a reinforcement layer, a self-adhesive layer and an isolation layer. The two layers of reinforcement layers are respectively compounded on the upper and lower surfaces of the polyolefin waterproof base layer. It is 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 co...
