摘要
聚氨酯密封剂是由异氰酸酯与羟基化合物在一定条件下反应,并加入各种填料而制得的.产品受反应温度、反应时间、反应物配比、催化剂等因素的影响.本文介绍了单组份聚氨酯胶粘密封剂的组成、制备工艺、性能表征,并对影响密封胶的一些主要因素进行了讨论.
Polyurethane sealant was composed of isocyanate and hydroxide group compounds with some fillers. The production was effected by temperature, time, mix of the reactant, cats etc. the single form polyurethane sealant's constitute technics , performance token and mostly factor of effecting sealant was discussed in this paper.
