Embodiment 1

[0038]First, take 12 parts by weight of plasticizer naphthenic oil KA105 and pour it into the reaction kettle, start the agitator, and heat it to 185°C; then take 50 parts by weight of tackifier H-15 small molecular weight polyisobutylene, 25 parts by weight of SBS resin, the SIS resin of 15 parts by weight, the light absorber titanium dioxide of 4.0 parts by weight and the calcium carbonate filler of 1.0 parts by weight are poured in the reaction kettle, keep the temperature in the reaction kettle at 185 ℃, close the stirrer after continuing 55min and make auto Glue, and then pour the colloid into the mold to cool to room temperature, cut the self-adhesive block, wrap it with release paper, and then get the self-adhesive used as the self-adhesive layer of the peel-off polymer self-adhesive waterproof membrane.

Embodiment 2

[0040] First, take 10 parts by weight of the plasticizer naphthenic oil KN4010 and pour it into the reaction kettle, start the agitator, and heat it to 170°C; then take 45 parts by weight of the tackifier H-15 small molecular weight polyisobutylene, 22 parts by weight of SBS resin, 16 parts by weight of SIS resin, 3.0 parts by weight of light absorbing agent titanium dioxide and 2.0 parts by weight of calcium carbonate are poured into the reactor, and the temperature in the reactor is kept at 170 ° C. After 60 minutes, close the agitator to make self-adhesive Then pour the colloid into the mold to cool to room temperature, cut the self-adhesive block, wrap it with release paper, and then get the self-adhesive used as the self-adhesive layer of the peel-off polymer self-adhesive waterproof membrane.

Embodiment 3

[0042] First, take 8 parts by weight of plasticizer naphthenic oil KN4006 and pour it into the reaction kettle, start the agitator, and heat it to 180°C; then take 55 parts by weight of tackifier H-50 small molecular weight polyisobutylene, 28 parts by weight of SBS resin, 18 parts by weight of SIS resin, 2.0 parts by weight of light absorbing agent titanium dioxide and 3.0 parts by weight of calcium carbonate are poured into the reaction kettle, and the temperature in the reaction kettle is kept at 180 ° C. After 60 minutes, close the agitator to make self-adhesive Then pour the colloid into the mold to cool to room temperature, cut the self-adhesive block, wrap it with release paper, and then get the self-adhesive used as the self-adhesive layer of the peel-off polymer self-adhesive waterproof membrane.

Abstract

The invention belongs to the technical field of waterproof materials of buildings, and particularly discloses an uncovering-free type macromolecule self-adhesion waterproof roll and a preparing method of the uncovering-free type macromolecule self-adhesion waterproof roll. According to the technical scheme, the uncovering-free type macromolecule self-adhesion waterproof roll comprises a plastic basic material, wherein the two sides of the upper surface of the plastic basic material is lap joint zones, the middle of the upper surface of the plastic basic material is a structural concrete bonding zone, and a self-adhesion layer and an isolating layer are arranged on the upper surface of the plastic basic material in a hot-compressing mode. The self-adhesion layer of the uncovering-free type macromolecule self-adhesion waterproof roll is composed of SBS resin, SIS resin, a plasticizer, a thickening agent, a light absorber and filling. The isolating layer made of active inorganic particles and capable of generating a hydration reaction with newly stirred cement-based materials is arranged on the self-adhesion layer. When the uncovering-free type macromolecule self-adhesion waterproof roll is used, materials of the isolating layer on the surface of the self-adhesion waterproof roll do not need to be uncovered, concrete can be poured directly, and a firm connecting interface is formed. Therefore, the uncovering-free type macromolecule self-adhesion waterproof roll has the advantages of being convenient to construct, capable of reducing resource waste, stable and reliable in the performance of being bonded with concrete and the like.

Description

Technical field [0001] The waterproof material technology field involved in the invention involved in the construction of buildings is specifically used in projects such as water conservancy and hydropower, tunnel subway, civil air defense work, and underground buildings.Its preparation method. Background technique [0002] Tunnel waterproof material is an integral part of the tunnel construction, and it is a key link that is related to the success or failure of tunnel construction.Due to the restrictions on waterproof materials, leakage of the tunnel has become one of the main diseases of the current tunnel construction.Statistics show that among more than 5,000 railway tunnels in China, 70%of the tunnels have leakage, and 1362 are severely leak, accounting for about 30%of the operating tunnel."Ten Tunnels and Nine Leaks "is a vivid portrayal of the leakage of the tunnel; the leakage of various foreign tunnels is as serious. [0003] There are many reasons for tunnel leakage, ma...
