Embodiment 1

[0028] Embodiment one sees figure 1 : This wet and sticky self-adhesive waterproof roll material 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 The layers are worn with suspenders 16, and the two ends of the suspenders are exposed for binding.

[0029] The self-adhesive sealing layer 12 has self-healing properties, cold construction, no solvent volatilization, safety and environmental protection, no fire hazard, convenient construction, and can be bonded in humid environment or 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 bitumen blend ECB or modified bitumen membrane. The polymer waterproof sheet or the modified aspha...

Embodiment 2

[0030] Embodiment two see figure 2 : In the case of facing construction, the non-woven fabric layer 15, the bonding layer 14 and the suspenders 16 can also be omitted.

[0031] The material of the above 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: any value from 30 to 50%.

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

[0035] Operating oil: any value from 5 to 35%, the operating oil can be naphthenic oil or third-line base oil.

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

[0037] Flow blocking agent: any value from 1 to 5%, and the flow blocking agent can choose fumed white carbon black.

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

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) Technical field [0001] The invention relates to a waterproof coiled material, a production method and a construction method thereof. (two), background technology [0002] The existing waterproof materials are mainly polymer SBS modified asphalt and synthetic polymer waterproof membranes, etc. High polymer SBS modified asphalt and synthetic polymer waterproof membranes are new waterproof materials with rapid growth in demand in recent years. It solves the defects of high-temperature flow and low-temperature brittleness of asphalt linoleum in the past, and has a wide range of construction. It is a waterproof product that is promoted and actively developed by the Ministry of Construction. However, the existing waterproof materials are constructed by base coat, heated by a blowtorch, or bonded with an adhesive, which is prone to produce oily fumes and toxic gases, which is harmful to the health of construction workers and pollutes the environment. Moreover, the existing wat...
