Description

一种耐水性好的聚氨酯密封胶
技术领域
本发明属于胶黏剂技术领域,具体涉及一种耐水性好的聚氨酯密封胶。
背景技术
聚氨酯密封胶系以聚氨酯橡胶及聚氨酯预聚体为主要成分的密封胶,此类密封胶具有高的拉伸强度、优良的弹性、耐磨性、耐油性和耐寒性,但耐水性欠佳,可分为加热硫化型、室温硫化型和热熔型三种,其中室温硫化型又有单组分和双组分之分。其广泛用于建筑物、广场、公路作为嵌缝密封材料,以及汽车制造、玻璃安装、电子灌装、潜艇和火箭等的密封。
发明内容
针对现有技术的不足,本发明提供一种耐水性好的聚氨酯密封胶,耐水性能好,具有高的拉伸强度、优良的弹性、耐磨性、耐油性和耐寒性。
本发明的技术方案是:一种耐水性好的聚氨酯密封胶,由以下重量份数的原料组成:聚氨酯树脂90-100份、双酚A环氧树脂30-35份、丁基橡胶15-20份、羟甲基纤维素钠5-8份、聚乙烯蜡3-5份、二乙烯基苯2-5份、滑石粉10-12份、乙酰柠檬酸三正丁酯3-5份、邻苯二甲酸烷基酯1-3份、松香季戊四醇酯5-10份、沥青1-2份,粉煤灰6-9份。
与现有技术相比,本发明优点在于:耐水性能好,具有高的拉伸强度、优良的弹性、耐磨性、耐油性和耐寒性。
