Abstract

The invention discloses a waterproof antifouling protection spray and a preparation method thereof, and relates to a mixture compound. The waterproof antifouling protection spray comprises the following components in percentage by mass: 10-15% of polytetrafluoroethylene micro powder, 5-10% of fatty alcohol-polyoxyethylene ether, 20-25% of glycolic acid, 10-15% of copper oleate, 10-15% of polyvinyl butyral, 20-25% of allyl alcohol, 3-5% of a nonionic fluorocarbon surfactant and 10-15% of an LPG propellant. After being sprayed, the waterproof antifouling protection spray disclosed by the invention has excellent properties of being good in lotus leaf dual-hydrophobicity, self-cleaning property, hydrophobicity, water resistance, antifouling property, scrubbing resistance and the like.

Description

technical field [0001] The invention relates to a mixture compound, in particular to a waterproof and antifouling protective spray and a preparation method thereof. Background technique [0002] Waterproof and antifouling protective spray is an aqueous dispersion of mixed compounds, which can form a special water-resistant structure (change the contact angle) after film formation, making the surface of the object extremely hydrophobic, water-repellent, and waterproof. At present, there are many kinds of waterproof and anti-fouling protective sprays, generally silicone emulsions, which are added to latex paint as additives, and there are certain requirements for the amount added. If the amount is small, the effect will be affected, and if the amount is too large, it will affect The quality of the paint film is high, and the price is relatively high, so it is not suitable for use in some low-grade materials. Silica sol is green and environmentally friendly, cheap and easy to ...
