Double-sided composite polymer waterproof coiled material, preparation method and application
The invention relates to the technical field of waterproof materials, and provides a preparation method and application of a double-sided composite polymer waterproof coiled material, the double-sided composite polymer waterproof coiled material comprises Kevlar fiber cloth, a polymer sheet layer, a self-adhesive layer and an isolating membrane from bottom to top in sequence, the self-adhesive layer is a polymer pressure-sensitive adhesive or butyl rubber, and the isolating membrane is a polyethylene film. The high-molecular pressure-sensitive adhesive is prepared from the following components in parts by weight: 20 to 28 parts of polystyrene-polyisoprene-polystyrene, 1 to 6 parts of styrene-butadiene-styrene, 10 to 15 parts of nitrile rubber, 2 to 5 parts of terpene resin, 1 to 7 parts of rosin resin, 15 to 25 parts of naphthenic oil, 6 to 10 parts of petroleum resin, 0.5 to 1 part of antioxidant, 0.3 to 5 parts of stabilizer and 1 to 5 parts of fluorosiloxane adhesion promoter. According to the technical scheme, the problems of low tensile strength, low elongation at break, low tearing strength and low bonding and peeling strength of the double-sided composite high-molecular waterproof roll in the prior art are solved.
本发明涉及防水材料技术领域，提出了一种双面复合型高分子防水卷材制备方法及应用，所述双面复合型高分子防水卷材，由下至上依次为凯夫拉纤维布、高分子片材层、自粘胶层、隔离膜，所述自粘胶层为高分子压敏胶或丁基胶，所述高分子压敏胶包括以下重量份组分：聚苯乙烯‑聚异戊二烯‑聚苯乙烯20‑28份、苯乙烯‑丁二烯‑苯乙烯1‑6份、丁腈橡胶10‑15份、萜烯树脂2‑5份、松香树脂1‑7份、环烷油15‑25份、石油树脂6‑10份、抗氧剂0.5‑1份、稳定剂0.3‑5份、氟硅氧烷助粘剂1‑5份。通过上述技术方案，解决了现有技术中双面复合型高分子防水卷材的拉伸强度、断裂伸长率、撕裂强度和粘结剥离强度低的问题。
