Description
技术领域
本发明涉及了一种助剂,具体的说,涉及了一种PU用高效复合助剂。
背景技术
聚氨酯(PU)是一种新型高分子材料,由黑料已氰酸酯和白料组合聚醚混合发泡而成。聚氨酯从种类上分为硬泡、半硬泡、软泡。硬泡产品主要用于保温、隔热、防水、防腐等方面,具体使用行业有外墙、冷库、化工厂、养殖场、太阳能行业等;半硬泡及软泡产品主要用于汽车、鞋厂、玩具厂等行业。为了改善聚氨酯的性能,聚氨酯产品制备过程中通常需要采用填充剂、阻燃剂、脱模剂、热稳定剂、光稳定剂、水解稳定剂、防霉剂等多种不同的助剂。为了保证防火性能,阻燃剂在聚氨酯中的应用越来越广泛,但是,很多阻燃剂中含有氯/溴基团容易造成环境污染。
为了解决以上存在的问题,人们一直在寻求一种理想的技术解决方案。

基于上述,所述小分子量树脂为聚含氟丙烯酰胺树脂、含氟环氧树脂或含氟聚苯醚;所述大分子量树脂为聚丙烯树脂、酚醛树脂
基于上述,所述大分子量树脂的分子量分布指数为1.1-1.3;所述小分子量树脂的分子量分布指数为2-3。
基于上述,SiO2、α-Al2O3、CuO、ZnO、MgO、Fe2O3、TiO2和K2O为固体粉末,粒径为50-80 nm,球形度为0.6-1。
基于上述,在先将SiO2、α-Al2O3、CuO、ZnO、MgO、Fe2O3、TiO2和K2O进行球磨,混合均匀,得到第一混合粉末;然后在20-30℃、N2气氛条件下,将第一混合粉末和小分子量树脂、大分子量树脂进行球磨,混合均匀,得到半成品,然后熔融挤出造粒,粉碎,即得。
基于上述,挤出采用双螺杆挤出机,熔融温度为100-300℃。
本发明相对现有技术具有突出的实质性特点和显著进步,具体的说,本发明提供的PU用高效复合助剂采用SiO2、Al2O3等无机组分起到阻燃抑菌效果,更加安全无污染,另外添加小分子量树脂和大分子量树脂,两种树脂和无机组分先球磨,再熔融挤出造粒,树脂熔融包覆于无机粉末表面,使得树脂和无机组分混合的更加均匀;同时,小分子量树脂采用含氟树脂,避免小分子树脂影响聚氨酯的阻燃和耐水性能。
