[0029] The preparation method of functionalized tri-mer & mean propylene rubber is not particularly limited, and the preparation method can be accumulated as follows: (1) Dissolving the non-sulfurized trihydrocene rubber in toluene; (2) heating the dissolved solution to 50 ° C ~ 100 ° C, and addable benzoyl dissolution; (3) add olefin monomer containing the ethylene duplex and epoxy group to the tri-mernened rubber solution, sufficiently reacted, separated, to obtain functionalization Three-membered ethylene rubber.
[0030] The self-viscous layer comprises a functionalized terranium ethylene ethylene ethylene ethylene rubber, rehabilitating asphalt, tackifier, Qilans accelerator, aluminum tetrachloride, tertiary amine promoter, cerium nitrate, antioxidant, UV absorption Division, calcium silicate and silica, when self-viscous layer is 100 parts by mass: functionalized triendal ethylene ethylene rubber is 10 ~ 70 parts by mass; the reimbursement is 10 ~ 70 parts by mass; the tacki...
Embodiment 1
[0049] The thermoplastic polyolefin is self-adhesive waterproof web, including a polyolefin waterproof base, a self-adhesive layer, and an isolation layer, two self-adhesive layers composite on the polyolefin waterproof base layer, lower surface, two isolation layers each composite two layers The outer surface of the viscous layer, the isolation film is commercial PET isolation membrane.
[0050] The polyolefin waterproof base layer has a thickness of 1 mm, and each content is as follows, a linear low density polyethylene 30 wt%, a gauge polypropylene 40 wt% and a maleic anhydride grafting modified polyethylene 30 wt%.
[0051] The self-adhesive layer has a thickness of 1 mm, and the combination and content in each of them are as follows: functionalized three-membered ethylene rubber 30 wt%, re-emphasized asphalt 40 wt%, C5 hydrocarbon resin 8 wt%, dioxide Tetracycline Qalaim 0.9 wt%, Aluminum chloride 0.5 wt%, triethylamine 0.1% by weight, cerium nitrate 0.1% by weight, 2,6-di-te...
Embodiment 2
[0053] The functionalized trihydropl rubber in the self-adhesive layer was changed from 30 wt% to 25 wt%, and the redeployment was changed from 40 wt% to 45 wt%, and other as Example 1.
