Problems solved by technology

However, most of the transparent coatings currently used are varnishes without any fillers. Although the transparency and decoration are good, there are common problems such as low hardness of the coating film, easy scratches, poor heat resistance, and easy yellowing under the action of ultraviolet light. , also does not have waterproof self-cleaning function

Abstract

The invention relates to a water-based paint with high transparency and hydrophobicity. The water-based paint comprises the following components: 30-40 parts of a fluorosilicone modified acrylic emulsion, 20-40 parts of pure-phase transparent powder YT-F690, 3-5 parts of hydroxypropyl methyl cellulose, 8-15 parts of deionized water, 3-5 parts of a wetting dispersant, 2-4 parts of an antifoaming agent, 1-2 parts of an antifreezing agent, 1-2 parts of a coalescing agent, 2-4 parts of a neutralizer AMP-95 and 0.5-1 part of a bactericide. The water-based paint disclosed by the invention not only has decoration and protection functions of common transparent paint, but also has good scratch resistance and high transparency and hydrophobicity.

Description

technical field [0001] The invention belongs to the field of environment-friendly coatings, in particular to a highly transparent and hydrophobic water-based coating. Background technique [0002] Since entering the 21st century, people have higher and higher requirements for decoration quality, and the demand for environmentally friendly coatings with high transparency and high mechanical properties has increased by leaps and bounds. A new type of art paint for exterior wall decoration art materials, which has the characteristics of ecological environmental protection, mildew and moisture resistance, and washability, but the decorative surface is rich in layers and uneven, and it is easy to focus on dust and affect the aesthetic effect. High transparency, hydrophobic water The application of paint makes the decorative art surface of the exterior wall have a self-cleaning function, and it will be as clean as new after a layer of rain. On the surface of automobile glass, whe...
