Abstract

The strontium aluminate paint is prepared with strontium aluminate powder in 30-45 wt%, carrier in 40-60 wt% and glaze powder in 8-20 wt%, and through mixing through stirring for 2-6 hr. The strontium aluminate paint capable of absorbing the impact energy of bullet and other powerful impact matters is suitable for being coated onto the surface of proper base to raise the impact resistance. The present invention also relates to impact resisting fiber fabric with coating of the strontium aluminate paint for making ballistic protective clothing.

Description

technical field [0001] The invention relates to the field of life-saving materials with impact resistance, in particular to a strontium aluminate paint capable of absorbing bullet energy, an impact-resistant coated fiber fabric manufactured by using the coating, and processed by using the coated fiber fabric Various life-saving protective items. Background technique [0002] Impact-resistant life-saving protective materials, such as bullet-proof life-saving products, especially bullet-proof clothing and related supplies, occupy an important position in the military and national defense construction, and their research and development have achieved remarkable results. Taking bulletproof clothing as an example, it has been recognized and widely used that it is made of aramid fiber or PE fiber. Aramid fiber (full name is "poly-paraphenylene terephthalamide" or "aromatic polyamide fiber") is a new type of synthetic fiber. Research results show that the breaking strength of aram...
