Problems solved by technology

[0006] However, the waterproof requirements of the vertical wall of the underground waterproof project are ignored, because the setting of the isolation protective layer makes the surface of the coiled material non-adhesive, so that the coiled material cannot be fully adhered to the vertical wall of the underground waterproofing project.

Abstract

The invention relates to a preparation method of a high-polymer self-adhesive waterproof roll. The technical scheme is as follows: the preparation method comprises the steps of fully coating an SIS (Styrene-Isoprene-Styrene) hot melt pressure sensitive self-adhesive on a main plastic high-polymer waterproof layer by using a hot melt pressure sensitive adhesive coating machine to form an SIS hot melt pressure sensitive self-adhesive layer; then, coating an anti-adhesive isolating membrane on the pressure sensitive self-adhesive layer to prepare a high-polymer self-adhesive waterproof roll product, wherein the main plastic high-polymer waterproof layer is a high-density polyethylene cross laminated film or modified high-density polyethylene film; the anti-adhesive isolating membrane is a silicon oil coated polyurethane isolating membrane. The preparation method has the beneficial effects that firstly, the roll can be permanently and organically combined with the concrete of a structural layer due to the application of the SIS hot melt pressure sensitive self-adhesive, so that no hidden water breakthrough dangers in the intermediate process are caused, and the reliability of a waterproof layer is improved; secondly, the high-polymer self-adhesive waterproof roll is excellent in impact and puncture resistance and capable of bearing the impact of a construction load directly acting on the high-polymer self-adhesive waterproof roll; thirdly, the high-polymer self-adhesive waterproof roll is relatively strong in chemical corrosion resistance and favorable in resistance to alkaline water from concrete; fourthly, the SIS hot melt pressure sensitive self-adhesive is strong in self-healing property.

Description

technical field [0001] The invention relates to a non-asphalt-based building waterproof coiled material, in particular to a preparation method of a polymer self-adhesive waterproof coiled material. Background technique [0002] In China, self-adhesive waterproof membrane is a new type of waterproof membrane developed after the 1990s. It is a development direction of building waterproof membrane in the world. Compared with traditional building waterproof membrane, it is mainly cold self-adhesive. Adhesive construction has the advantages of no open flame, not easy to cause fire, no solvent pollution, safe, environmentally friendly and convenient construction, etc., and is favored by the building waterproofing industry, especially the construction unit. Therefore, it has developed rapidly in China in recent years. However, at present, the self-adhesive adhesive used in this type of waterproof membrane in China is still mainly modified asphalt, which leads to technical defects ...
