用途


1.主要用于双马来酰亚胺树脂(Bismaleimide 简称BMI)的改性,可大幅度降低BMI树脂的应用成本,改善BMI树脂的操作性和工艺性。提高BMI树脂的韧性及耐热性、成模性。

可用于:①电器绝缘材料、覆铜线路板耐高温浸渍漆、层压板、模压塑料等。②耐磨材料、金刚石砂轮、重负荷砂轮、刹车片、耐高温轴承粘合剂等。③航空航天结构材料。④功能性材料。

2.用于橡胶的防老剂,在橡胶中加入1-3‰的DABPA,可大大提高橡胶的耐老化程度。

usage:

1, mainly used for  bismaleimide  (BMI) modification, can reduce the cost of the application of BMI resin, improve the operability and manufacturability of BMI resin.

  improve BMI resin toughness and heat resistance and ChengMo.

 (1) high temperature resistant dipping paint of electrical insulating materials, copper clad laminates, laminate, moulded plastic.

(2) the wear-resisting material, diamond wheel, brake pads, high temperature resistant bearing adhesives.

(3). The aerospace structure materials.

(4) functional materials.

 

2. The rubber stabilizer. Add 1-3% in rubber.

DABPA can greatly improve the degree of resistance to aging of rubber.
