Embodiment 1

[0028] Example 1 see figure 1 : This wet stickable self-adhesive waterproof membrane 1 is sequentially laminated with the following layers: isolation layer 11, self-adhesive sealing layer 12, polymer waterproof sheet 13, adhesive layer 14, flexible protective layer 15, the above-mentioned flexible protective layer A sling 16 is worn on the layer, and both ends of the sling are exposed for binding.

[0029] The self-adhesive sealing layer 12 has self-healing, cold construction, no solvent volatilization, safety and environmental protection, no fire hazard, convenient construction, and can be bonded in a humid environment or in water. The material of the above-mentioned polymer waterproof sheet 13 can be selected from high-density polymer Ethylene HDPE, Low Density Polyethylene LDPE, Polyvinyl Chloride PVC, Polyvinyl Acetate EVA, Ethylene, Vinyl Acetate Asphalt Blend ECB or Modified Asphalt Membrane. The thickness of the above-mentioned polymer waterproof sheet or modified bitu...

Embodiment 2

[0030] See Example 2 figure 2 : In the case of positive sticking construction, the non-woven fabric layer 15, the adhesive layer 14 and the suspender 16 can also be omitted.

[0031] The material of the above-mentioned self-adhesive sealing layer is butyl rubber modified asphalt, and the weight ratio is as follows:

[0032] Butyl rubber 268; any value from 8 to 28%.

[0033] High-quality oxidized asphalt: 30-50% of any value.

[0034] Acrylic water-absorbent resin: any value from 1 to 8%.

[0035] Operating oil: 5~35% of any value, operating oil can choose naphthenic oil or three-line base oil.

[0036] Filler: 5~25% of any value, the filler can choose fossil powder or carbon black.

[0037] Blocking agent: any value from 1 to 5%, the blocking agent can be selected from fumed silica.

[0038] The production method of the above-mentioned wet stickable self-adhesive waterproof membrane is made of butyl rubber and high-quality oxidized asphalt through high temperature mixin...

Abstract

The present invention relates to a wet-stickable self-adhesive water-proof sheet material, its production method and construction method. It is characterized by that said invention uses butyl rubber and high-grade oxidated asphalt, makes them undergo the process of high-temperature mixing treatment, adds acryl water-absorbing resin, operation oil, filler and flow-resisting agent, makes them undergo the process of high-speed dispersion treatment so as to obtain self-adhesive seal water-proof material, dip-coating said self-adhesive seal water-proof material onto one surface of high-molecular water-proof sheet material carrier, then makes the above-mentioned material undergo the processes of calendaring, extruding and layering isolating layer as anti-adhesion layer, then makes a flexible protective layer be stuck on another surface of the above-mentioned high-molecular water-roof sheet material, so that the invented wet-stickable self-adhesive water-proof sheet material can be obtained.

Description

(1) The technical field [0001] The present invention relates to a waterproof coil material and its production method and construction method. (2) Background technology [0002] The existing waterproof materials are mainly polymer SBS modified asphalt and synthetic polymer waterproofing membranes. It solves the defects of high temperature flow and low temperature embrittlement of asphalt linoleum in the past, and has a wide construction range. It is a waterproof product promoted and actively developed by the Ministry of Construction. However, the existing waterproof materials are constructed with base coats, heated and baked with a blowtorch, or bonded with adhesives, which are prone to produce oil fumes and toxic gases, which are detrimental to the health of construction workers and pollute the environment. In addition, the existing waterproof materials have high requirements on the flatness and moisture content of the base layer, and the moisture content of the base layer ...
