preparation example Construction
[0029] 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.
[0030] 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
[0049] The thermoplastic polyolefin self-adhesive waterproof membrane comprises a polyolefin waterproof base layer, a self-adhesive layer and an isolation layer. On the outer surface of the adhesive layer, the release film is a commercial PET release film.
[0050] The thickness of the polyolefin waterproof base layer is 1mm, and the contents are as follows: 30wt% of linear low-density polyethylene, 40wt% of syndiotactic polypropylene and 30wt% of maleic anhydride graft-modified polyethylene.
[0051] The thickness of the self-adhesive layer is 1mm, and the combinations and contents are as follows: functionalized EPDM rubber 30wt%, heavy traffic asphalt 40wt%, C5 hydrogenated petroleum resin 8wt%, tetramethylthiuram disulfide 0.9wt%, Aluminum trichloride 0.5wt%, triethylamine 0.1wt%, cerium ammonium nitrate 0.1wt%, 2,6-di-tert-butyl p-cresol 0.2wt%, p-octylphenyl salicylate 0.2wt%, Calcium silicate 10wt% and silicon dioxide 10wt%.
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.
