High-temperature-resistant flame-retardant polyurethane composite material and preparation method thereof
The invention relates to the technical field of high polymer material modification, in particular to a high-temperature-resistant flame-retardant polyurethane composite material. The polyurethane composite material is composed of the following components in parts by weight: 70-100 parts of phenol-based Mannich polyether polyol, 70-80 parts of polyisocyanate, 3-10 parts of a foaming agent, 0.5-5 parts of an ammonium catalyst, and 1-1.2 parts of a foam stabiliser, wherein the foaming agent is alkane, and the polyisocyanate is formed by mixing diphenylmethane diisocyanate and toluene diisocynateaccording to a weight ratio of 3: 2. The obtained polyurethane composite material is resistant to high temperature; test results show that the combustion growth rate index of the produced material islow and the heat conductivity coefficient is small; the change rate of a product size before and after high-temperature testing is small; and the preparation method is simple in process and suitable for large-scale industrial popularization.
本发明涉及高分子材料改性技术领域，具体涉及一种耐高温阻燃聚氨酯复合材料，其中阻燃聚氨酯泡沫复合材料由如下重量份数的各组分组成：苯酚基曼尼希聚醚多元醇70～100份；多异氰酸酯70‑80份；发泡剂3～10份；铵类催化剂0.5～5份；泡沫稳定剂1～1.2份，其中发泡剂为烷烃，多异氰酸酯是以重量比计按照二苯基甲烷二异氰酸酯/甲苯二异氰酸酯＝3:2的方式混合而成，本发明所得聚氨酯复合材料高温耐受，经测试产品燃烧增长速率指数低，导热系数小，并且经过高温测试前后产品尺寸变化率小，制备方法简单，适合大规模工业化推广。
