Rainproof agent for automobile rearview mirror and preparation method thereof

Abstract

The invention provides a vehicle rearview mirror anti-rain agent and a preparation method thereof. The preparation method of the vehicle rearview mirror anti-rain agent comprises mixing deionized water, polyether-modified organosiloxane, a surfactant, propylene glycol butyl ether and an aqueous resin emulsion through two stirring processes to obtain the vehicle rearview mirror anti-rain agent. The preparation method is simple. The vehicle rearview mirror anti-rain agent has excellent film-forming properties and super hydrophilicity, and can form a hydrophilic film on the surface of the vehicle rearview mirror after coating the vehicle rearview mirror so that water beads on the vehicle rearview mirror surface are fast spread, water condensation is prevented, the surface of the vehicle rearview mirror is bright and clean and visibility is improved. The vehicle rearview mirror anti-rain agent is prepared through the above method, has excellent film-forming properties and super hydrophilicity, keeps the vehicle rearview mirror surface bright and clean and has a lasting rainproof function.

Description

technical field [0001] The invention relates to the field of rainproof agents, in particular to a rainproof agent for automobile rearview mirrors and a preparation method thereof. Background technique [0002] Automobiles are "machines that change the world" and wheels that drive social progress. Automobiles have become an indispensable part of our daily lives. The widespread use of automobiles has changed the economic and social structure, forming a new set of economic, cultural, and living systems, improving people's quality of life, promoting social progress, and promoting economic development. [0003] At present, with the rapid economic development, the number of automobiles in my country has exceeded 100 million, and it is still growing. Automobiles have greatly facilitated people's lives, but they have also brought a series of traffic safety hazards. According to the statistics of relevant departments, 70% of major automobile traffic accidents occur in rainy days and...

AI Technical Summary

Problems solved by technology

However, at present, the surface tension of domestic hydrophilic rainproof agents is usually around 30mN / m, and the spreading speed of the solution is relatively slow, which may easily cause water droplets to condense, thus affecting the line of sight. Solvents or hydrophilic surfactants are easily washed away by rain, resulting in product failure and poor durability
