Roof waterproof heat insulation coiled material and preparation method thereof
The invention relates to the field of waterproof heat insulation materials, and discloses a roof waterproof heat insulation coiled material and a preparation method thereof.The coiled material comprises a base layer, a heat insulation layer, a waterproof layer, a bonding layer and a diaphragm layer which are sequentially connected; wherein the heat insulation layer is formed by compounding foamed polyurethane and a phase change material, and the raw materials of the foamed polyurethane comprise polyether polyol, diphenylmethane diisocyanate, toluene diisocynate and a hydroxyl-containing flame retardant; the mass ratio of the diphenylmethane diisocyanate to the toluene diisocynate is 1: (1.5-3.5), the mass ratio of the polyether polyol to the hydroxyl-containing flame retardant is 10: (1-4), the phase-change material is selected from polyethylene glycol, paraffin or fatty acid, and the mass of the phase-change material accounts for 10%-30% of that of the thermal insulation layer. By introducing the phase change material (such as polyethylene glycol, paraffin and fatty acid) into the heat insulation layer of the coiled material, compared with a traditional polymer base material in the prior art, dynamic temperature adjustment can be achieved, and the heat insulation performance of the material is optimized.
本申请涉及防水隔热材料领域，公开了一种屋面防水隔热卷材及其制备方法，所述卷材包括顺次连接的胎基层、隔热层、防水层、黏结层及隔膜层；其中，所述隔热层由发泡聚氨酯与相变材料复合形成，所述发泡聚氨酯的原料包括聚醚多元醇、二苯基甲烷二异氰酸酯、甲苯二异氰酸酯和含羟基阻燃物；所述二苯基甲烷二异氰酸酯与甲苯二异氰酸酯的质量比为1:(1.5‑3.5)，所述聚醚多元醇与含羟基阻燃物的质量比为10:(1‑4)，相变材料选自聚乙二醇、石蜡或脂肪酸，所述相变材料的质量占隔热层的10％‑30％。通过在卷材的隔热层中引入相变材料(如聚乙二醇、石蜡、脂肪酸)，相较于现有技术的传统聚合物基材，能够实现动态的温度调节，优化了材料的隔热性能。
