Embodiment 1

[0054] This reactive rubber composite waterproof membrane is composed of a base layer and a surface layer, the base layer is an EPDM waterproof layer, and the surface layer is a reactive butyl rubber reaction layer;

[0055] The proportioning of each component of the base rubber is in parts by weight, based on 100 parts of EPDM rubber, and the content of other components is:

[0056]

[0057] The proportioning of each component of the surface layer rubber is in parts by weight, based on 100 parts of butyl rubber, and the content of other components is:

[0058]

[0059] In this example, the reactive rubber composite waterproof coiled material is produced by a continuous compounding process. First, the base layer EPDM rubber is extruded and vulcanized; it enters the calender and is compounded with the surface layer butyl rubber, and the composited coiled material is cooled, Trimming, counting, inspection, crimping and packaging are completed continuously and synchronously...

Embodiment 2

[0077] This reactive rubber composite waterproof membrane is composed of a base layer and a surface layer, the base layer is an EPDM waterproof layer, and the surface layer is a reactive butyl rubber reaction layer;

Abstract

The invention relates to a reactive rubber composite water-proof roll and a production method thereof, wherein the reactive rubber composite water-proof roll is formed by compounding a base layer and a surface layer; the base layer is an ethylene propylene terpolymer water-proof layer; the surface layer is a reactive butyl rubber reaction layer; the base layer rubber comprises other components in parts by weight based on 100 parts of ethylene propylene terpolymer: 3-8 parts of zinc oxide, 1-2.5 parts of stearic acid, 0.3-4 parts of polyethylene glycol, 1-5 parts of wax, 50-100 parts of fast extruding furnace black, 5-40 parts of calcium carbonate, 20-80 parts of plasticizer, 0.2-1.0 part of accelerator TMTD (Tetramethyl Thiuram Disulfide), 0.5-3 parts of accelerator M, 0.5-2 parts of accelerator CZ and 0.8-5 parts of sulfur; surface layer rubber comprises other components in parts by weight based on 100 parts of butyl rubber: 10-50 parts of highly abrasion resistant carbon black, 5-30 parts of superfine talcum powder, 20-80 parts of sulfate aluminum cement, 0.1-5 parts of lithium chloride, 1-10 parts of calcium chloride, 0.08-1.2 parts of calcium stearate and 0.5-5 parts of polyethylene glycol. The reactive rubber composite water-proof roll and concrete can form a whole body just like that a rubber skin is implanted into a concrete surface layer without causing phenomenon of water channeling.

Description

1. Technical field [0001] The invention relates to a waterproof coiled material, in particular to a reactive rubber composite waterproof coiled material and a production method thereof. 2. Background technology [0002] 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, coatings and asphalt coils. Among them, the products of coils are all treated with base treatment agents or adhesives during construction. ...
