Waterproof coating

Abstract

The invention relates to a waterproof coating. The waterproof coating comprises, by weight, 40-50% of a film forming agent, 0.1-1% of water-based amino resin, 0.1-3% of hydrophobic nano-silica, 0.1-3%of modified diatomite, 0.1-3% of polycaprolactone and 40-60% of a lotus leaf hydrophobic agent. The waterproof coating is a colorless and transparent coating substance with a waterproof function, andcan be directly applied to a mobile phone circuit board or a mobile phone shell to achieve waterproof and dustproof effects.
