Problems solved by technology

[0002] Synthetic polymer waterproof membrane has good physical properties, but because its surface is not easy to bond, it is difficult to fail to achieve the ideal application effect
Some people try to cold-coat a layer of double-sided self-adhesive membrane on the surface of the polymer membrane, but it is easily peeled off; It is difficult to bond the surface of the surface, and the test did not take measures to treat the surface of the polymer coil. In addition, the self-adhesive does not match, so the effect is almost the same as the former.
It can be seen that the technology of trying to coat a layer of self-adhesive on the surface of polymer coils is full of challenges

preparation example Construction

[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...

Embodiment 2

[0053] 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.

Abstract

The invention relates to the technical field of waterproof coiled material, in particular to a reactive polymer self-adhesive waterproof coiled material. The purpose of the present invention is to provide a polymer self-adhesive waterproof membrane with high peel strength, high tensile strength, good low temperature resistance, good aging resistance and good waterproof effect. The reactive polymer self-adhesive waterproof membrane of the present invention comprises a polyolefin waterproof base layer, a reinforcement layer, a self-adhesive layer and an isolation layer. Layers are 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. It is characterized in that the self-adhesive layer contains functionalized EPDM, and the poly The olefin waterproof base layer contains polyethylene, polypropylene and maleic anhydride graft modified polyethylene.
