黑色耐磨防腐导电涂料的研制

利用有机硅树脂对环氧树脂进行改性,添加了一定量的纳米二硫化钼、纳米铝粉、导电碳黑和石墨,制作了一种黑色耐磨防腐导电涂料。实验表明,当有机硅树脂用量为12%,填料为8%,混合溶剂组成为m(丙酮):m(醋酸乙酯):m(醋酸丁酯):m(二甲苯)=2:1:1:1、用量为48%时,所得涂料耐磨性和防腐性能良好,涂层表面电阻达到了2.2×104?/cm2,具有较好的导电和防电磁性能。该涂料可以应用于陆军武器装备表面的电磁防护。

Preparation of black wear-resistant and corrosion-protective conductive coating

A black wear-resistant and corrosion-protective conductive coating was prepared by using organic silicon resin modified epoxy resin and adding a certain amount of nano-MoS2,nano-aluminum powder,conductive carbon black,and graphite.The experimental results indicated that when dosing 12% of organic silicon resin,8% of filler,and 48% of mixed solvent with m(acetone):m(ethyl acetate):m(butyl acetate):m(xylene) equal to 2:1:1:1,the coating obtained features good wear resistance and corrosion resistance,and has a surface resistance up to 2.2 × 104 ?/cm2,showing good conductive and electromagnetic protection properties and being suitable for the electromagnetic protection of land forces weapons and equipments.
