Problems solved by technology

[0003] 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

[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...

Abstract

The invention relates to the technical field of waterproof rolls, in particular to a thermoplastic polyolefin self-adhesive waterproof roll. The purpose of the present invention is to provide a thermoplastic polyolefin self-adhesive waterproof coiled material with high peel strength, good low-temperature bendability, good aging resistance and good waterproof effect. The thermoplastic polyolefin self-adhesive waterproof membrane of the present invention comprises a polyolefin waterproof base layer, a self-adhesive layer and an isolation layer. The outer surface of the self-adhesive layer is characterized in that the self-adhesive layer contains functionalized EPDM rubber, and the polyolefin waterproof base layer contains polyethylene, polypropylene and maleic anhydride graft-modified polyethylene.

Description

Technical field [0001] The present invention relates to the field of waterproof web technology, and more particularly to a high molecule self-adhesive waterproof coil having a high peeling strength. Background technique [0002] Synthetic polymer waterproof coils (including synthetic resin sheets and synthetic rubber coils) have good physical properties, but because their surface is not easy to bond, the ideal application effect is not met. Therefore, this type of waterproof coil market share has been small. [0003] Some people try to cool a double-sided self-adhesive wrap on the surface of the polymer coil, but it is easy to be peeled off; and some people have tried to adopt a method of heat-applying the surface of the polymer coil, but due to polymer coils The surface is difficult to bond, the test does not take treatment measures to the surface of the polymer coil, plus, from the adhesive, therefore, is different from the former effect. It can be seen that the technique attem...
