背景技术Background technique
金属表面防锈是工业生产中的重要课题，传统的防锈液、防锈油有优点也有缺点。普通防锈水中含大量的亚硝酸钠，有致癌性，不利于环保和人身体健康，而采用保湿剂延长防锈水的寿命，又带来沾手、沾灰尘的弊病，且不能长期防锈；一般硬膜防锈油虽然适合长期防锈，成膜也透明美观，但是无色透明的树脂种类较少，不稳定也易氧化变色，还需要有机溶剂溶解，带来易燃易爆的危险也不利于环保和健康；一般的防锈油使用矿物油，难降解，而且用于短期防锈时也会带来除油难的问题。因此，研究综合性能更加优异，针对不同场合研究更加适合的防锈产品是新的方向和趋势。Metal surface rust prevention is an important issue in industrial production. Traditional rust preventive liquids and rust preventive oils have advantages and disadvantages. Ordinary rust-proof water contains a large amount of sodium nitrite, which is carcinogenic, which is not conducive to environmental protection and human health. The use of moisturizers prolongs the life of rust-proof water, and brings the disadvantages of hand and dust, and can not prevent rust for a long time; Generally, although the hard film rust preventive oil is suitable for long-term rust prevention, the film formation is transparent and beautiful, but the colorless and transparent resin is less in kind, unstable and oxidatively discolored, and requires organic solvent to dissolve, which brings the risk of flammability and explosion. It is not conducive to environmental protection and health; the general anti-rust oil uses mineral oil, which is difficult to degrade, and it is also difficult to remove oil when used for short-term anti-rust. Therefore, the comprehensive performance of research is more excellent, and it is a new direction and trend to study more suitable anti-rust products for different occasions.
