一种冷喷锌用金属闪光封闭剂
摘要：
本发明公开了一种冷喷锌用金属闪光封闭剂，其配方含有以下重量份数的各组分：铝粉8～10份、有机溶剂40～50份、热塑性树脂30～35份、消泡剂0.5～1份、气相白炭黑1～5份、防沉剂0.1～0.4份、环氧改性助剂0.6～0.8份。本发明的冷喷锌用金属闪光封闭剂，选用三甲苯、异丙醇、二甲酯、醋酸正丁酯、正丁醇、乙二醇丁醚醋酸酯中的一种或两种为有机溶剂，既可以很好溶解配套树脂又不会对冷喷锌造成咬底，环氧改性助剂可以延缓锌盐生成速率提高冷喷锌防腐性能，同时消泡剂也可以进一步的解决起泡问题。本发明的冷喷锌用金属闪光封闭剂，可以解决配套油漆很容易造成咬底和容易起泡的技术问题，同时提高了冷喷锌的防腐能力。
摘要（英）：

The invention discloses a metal flash sealing agent for cold sprayed zinc. The sealing agent comprises, by weight, 8-10 parts of aluminum powder, 40-50 parts of organic solvents, 30-35 parts of thermoplastic resin, 0.5-1 part of defoaming agents, 1-5 parts of fumed silica, 0.1-0.4 part of an anti-setting agent and 0.6-0.8 part of an epoxy modified assistant. According to the metal flash sealing agent for the cold sprayed zinc, one or two of trimethylbenzene, isopropanol, dimethyl, n-butyl acetate, n-butanol and butyl cellosolve acetate serve as the organic solvents, supporting resin can be well dissolved, and lifting can not happen to the cold sprayed zinc. The epoxy modified assistant can reduce the generation speed of zinc salt and improve corrosion resistance of the cold sprayed zinc. Meanwhile, the defoaming agent can further solve the foaming problem. The metal flash sealing agent for the cold sprayed zinc can solve the technical problem that supporting paint easily causes lifting and is prone to foaming, and meanwhile the corrosion prevention capacity of the cold sprayed zinc is improved.
