Pre-laid polymer waterproof coiled material with capillary crystallization function and preparation method of pre-laid polymer waterproof coiled material
The invention discloses a pre-laid polymer waterproof roll with a capillary crystallization function, which comprises a waterproof sheet layer, a mixed particle layer and a pressure-sensitive adhesive layer, and the waterproof sheet layer comprises the following raw materials by weight: 70-80 parts of high density polyethylene, 5-10 parts of low density polyethylene, 0.01-0.5 part of a surface modifier, 5-7 parts of a macromolecular coupling agent, 0.01-0.5 part of an anti-aging agent, and 1-5 parts of a flame retardant. The mixed particle layer is prepared from the following raw materials in parts by weight: 30-50 parts of Portland cement, 0.5-1 part of a water reducing agent, 1-3 parts of a defoaming agent and 1-3 parts of a retarder, and the pressure-sensitive adhesive layer is prepared from the following raw materials in parts by weight: modified polystyrene-butadiene-styrene, C9 petroleum resin, polyisobutene, a softening agent, a phosphite antioxidant and siloxane. And a titanate coupling agent. Compared with the prior art, the method has the advantage that the problem of leakage caused by the glue failure defect of the lap joint edge of the high-molecular pre-laid waterproof roll and the situation that pinholes are formed in the lap joint process is solved.
本发明公开了具有渗透结晶功能的预铺高分子防水卷材，包括防水片材层、混合颗粒层、压敏胶层，所述防水片材层包括以重量份数计的以下原料：高密度聚乙烯70～80份、低密度聚乙烯5～10份、表面改性剂0.01～0.5份、大分子偶联剂5～7份、抗老化剂0.01～0.5份、阻燃剂1～5份，所述混合颗粒层包括以重量份数计的以下原料：硅酸盐水泥30～50份、减水剂0.5～1份、消泡剂1～3份、缓凝剂1～3份，述压敏胶层包括以重量份数计的以下原料：改性聚苯乙烯‑丁二烯‑苯乙烯份，C9石油树脂份，聚异丁烯份，软化剂份，亚磷酸酯抗氧剂份，硅氧烷，钛酸酯偶联剂。本发明与现有技术相比优点在于，解决了高分子预铺防水卷材搭接边开胶缺陷和在搭接过程中形成针孔的情况而造成的渗漏问题。
