A kind of self-adhesive reactive EPDM composite waterproof membrane and production method thereof

Abstract

The invention relates to a self-adhered reactive ethylene-propylene-diene monomer rubber composite waterproof roll and a production method thereof. The self-adhered reactive ethylene-propylene-diene monomer rubber composite waterproof roll is made by stacking and compositing a base layer, a face layer and a nonstick isolating layer; the base layer is an ethylene-propylene-diene monomer rubber waterproof layer; the face layer is self-adhered reactive butyl rubber layer; the nonstick isolating layer is a PE (polyethylene) nonstick isolating film. with 100 parts of the butyl rubber as reference, other components include 50 to 110 parts of polyisobutene, 5 to 10 parts of amorphous Alpha-olefin copolymer, 12 to 25 parts of tackifying resin, 100 to 180 parts of desulfuration gypsum, 80 to 120 parts of bentonite, 0.1 to 2 parts of lithium chloride, 1 to 10 parts of calcium chloride, 0.08 to 1.2 parts of calcium stearate, 10 to 50 parts of expanding agent, and 0.5 to 3 parts of cross-linking agent. The self-adhered reactive ethylene-propylene-diene monomer rubber composite waterproof roll has the advantages that water enters a water leak, a water-swelling member slowly swells under the action of the water and plugs the water leak, and thus self-repair of stopping water via water is achieved.

Description

[0001] 1. Technical field [0002] The invention relates to the field of building waterproof sealing, in particular to a self-adhesive reactive EPDM composite waterproof coiled material and a production method thereof. [0003] 2. Background technology [0004] In underground building structures, due to the soft foundation, uneven settlement, and high groundwater level, water leakage often occurs in underground structures. It is difficult to achieve the waterproof performance of concrete itself. According to previous studies, the concrete structure with micro-cracks of 0.02mm will begin to leak water. Therefore, for underground structures with high waterproof requirements, a continuous outer waterproof layer is a must. prepared conditions. The existing waterproof materials used for underground concrete structures are generally three types of waterproof products: polymer coils, asphalt coils and coatings. Among them, the coils are treated with base treatment agents or adhesives...

AI Technical Summary

Problems solved by technology

[0010] An object of the present invention is to provide a self-adhesive reactive EPDM composite waterproof membrane, which is used to solve the problem of existing waterproof products combined with concrete. If there is a leakage point, the material itself cannot repair itself; another object of the present invention is to provide a production method for this self-adhesive reactive EPDM composite waterproofing membrane
