Environmentally-friendly quick-drying copper door sealant and preparation method thereof

The invention discloses an environmentally-friendly quick-drying copper door sealant. A preparation method of the environmentally-friendly quick-drying copper door sealant comprises the following steps: mixing nanometer calcium carbonate powder with stearic acid and a coupling agent, processing the obtained mixture, a polydimethylsiloxane with a molecular weight of 5000 and a polydimethylsiloxanewith a molecular weight of 20000 to obtain a base material, and stirring and cooling the prepared base material, methyltrimethoxysilane, vinyltrimethoxysilane, titanate chelated titanium, gamma-aminopropyltriethoxysilane, dibutyltin dilaurate and a water removal agent in a star stirrer to finally prepare the copper door sealant. The above ingredients are combined with the preparation method, so the produced copper door sealant has the advantages of extremely high viscosity, high complete curing speed, no corrosion to copper materials, environmental friendliness and anticorrosion. 本发明公开了一种环保快干铜门密封胶，通过将纳米碳酸钙粉在与硬脂酸和偶联剂混合
