Silica sol composite curing agent, preparation method thereof and application of silica sol composite curing agent in fuse
The invention provides a silica sol composite curing agent, a preparation method thereof and application of the silica sol composite curing agent in a fuse. The acidic silica sol and the calcium oxide powder are introduced into the raw materials of the silica sol composite curing agent, and the calcium oxide reacts with water in the acidic silica sol to generate heat, so that rapid curing can be realized, the curing time is greatly shortened, and the production efficiency is improved. Nano Fe powder and a Cu anti-corrosion agent are further introduced into the raw materials of the silica sol composite curing agent, so that the oxidation corrosion resistance of Cu can be improved, the oxidation resistance of a silver-copper composite melt material in the fuse can be further improved, and the fuse adopting the curing agent can prevent the silver-copper composite melt material in the fuse from being oxidized and corroded; and the resistivity stability and the interface bonding strength are ensured. And meanwhile, as the raw materials in the curing agent are uniformly mixed, the texture uniformity of the arc extinguishing filler of the fuse is improved, the corrosion of a copper bar is effectively reduced, and the stability of the resistivity of a silver-copper composite melt material in the fuse is maintained.
本发明提供了硅溶胶复合固化剂及其制备方法和在熔断器中的应用。所述硅溶胶复合固化剂的原料引入了酸性硅溶胶和氧化钙粉末，利用氧化钙与酸性硅溶胶中的水发生反应自生热，可以实现快速固化，大幅减低固化时间，提升生产效率。所述硅溶胶复合固化剂的原料中还引入了纳米Fe粉和Cu防蚀剂能够提高Cu的抗氧化腐蚀性，进一步有利于提高熔断器中的银铜复合熔体材料的抗氧化性，使采用上述固化剂的熔断器可以实现防止熔断器中的银铜复合熔体材料氧化腐蚀，保证电阻率稳定及界面结合强度。同时由于上述固化剂中各原料均匀混合提高了熔断器灭弧填充物的质地均一性，有利于有效的减少铜条锈蚀，维持熔断器中的银铜复合熔体材料电阻率的稳定。
