自主开发、适用于反应注射成型(RIM)工艺制造高性能聚氨酯弹性体或微孔弹性体材料的聚氨酯(PU)原液,由多元醇、扩链剂、色浆、抗老化剂、催化剂等组成,其中催化剂为有机铋、有机锌、有机锆等环保催化剂中的一种或多种。在相同基础配方条件下,相对有机锡类催化剂,含上述环保催化剂配制的原液具有更好的贮存稳定性,所制材料的致密度和硬度较高,力学性能优良,且耐老化性好,可用于汽车等交通工具的外饰件。
The polyurethane (PU) stock solution developed independently for RIM process to make high-performance polyurethane elastomer or micro-hole elastomer material is composed of polyol, chain extender, colorant, anti-aging agent and catalyst, Wherein the catalyst is one or more of organic bismuth, organozinc, organozirconium and other environment-friendly catalysts. In the same basic formula conditions, the relative organotin catalysts, with the preparation of the above-mentioned environmentally friendly catalyst has better storage stability of the stock solution, the material made of high density and hardness, good mechanical properties, and good aging resistance, available Exterior parts for vehicles such as vehicles.
