Description

一种快速固化的酚醛环氧涂料
技术领域
本发明涉及化工涂料领域,尤其是一种快速固化的酚醛环氧涂料。
背景技术
环氧树脂是指那些分子中至少含有两个反应性环氧基团的树脂化合物,环氧树脂经固化后有许多突出的优异性能,对各种材料特别是金属的黏着力很强、有很强的耐化学腐蚀性、力学强度高、耐腐蚀等。酚醛环氧树脂(EPN)化学名称线型酚醛多缩水甘油醚,平均分子量600,是一种耐热性环氧树脂。环氧树脂粉末在防腐领域常见的应用便是作为涂料使用,环氧树脂粉末涂料的固化速度慢,涂装生产效率低,造成了一定的应用局限。
发明内容
本发明的目的在于提供一种快速固化的酚醛环氧涂料。
本发明的目的可以通过以下技术方案实现:一种快速固化的酚醛环氧涂料,其组分及其重量份为:双酚A 型环氧树脂100 份、酚醛环氧树脂15-20 份、高岭土5-10 份、云母石5-10 份、石蜡8-15 份、颜料30-40 份、固化剂2-8 份、流平剂0.5-5 份、氢氧化镁10-20份。
本发明组分及其重量份优选为:双酚A 型环氧树脂100 份、酚醛环氧树脂15 份、高岭土8 份、云母石6 份、石蜡10 份、颜料35 份、固化剂5 份、流平剂3 份、氢氧化镁12份。
所述颜料为钛白、铁红、镉红或云母氧化铁。
本发明的制备方法如下:按配方称量物料后,依次加入双酚A 型环氧树脂、酚醛环氧树脂、固化剂、氢氧化镁、高岭土、云母石、石蜡、颜料、流平剂,将物料经高速混合机预混合5min,再用熔融挤出混合机进行熔融挤出混合,混炼段温度控制在100℃ ;将熔融挤出混合物料用冷却辊进行冷却,将物料破碎,再用空气分级磨进行细粉碎和分级,最后用旋转筛分级过筛得产品。
本发明的有益效果:本发明制备的涂料具有低的固化温度、耐热性好、附着力强、力学性能高。
