AI Technical Summary

Problems solved by technology

Ordinary fluorescent paints are solvent-based products with high VOC content, which is easy to cause harm to the environment and is not conducive to energy saving and emission reduction. At present, some cities in my country have issued restrictions on VOC, so the use of solvent-based fluorescent paints is also increasing. Most of them are restricted. Water-based coatings are less harmful to the environment and construction personnel due to their extremely low VOC content, so they have been vigorously promoted by the country.

Abstract

The invention provides waterborne alkyd fluorescent paint which is prepared from, by weight, 30-45 parts of waterborne alkyd resin, 25-40 parts of fluorescent powder, 1-2 parts of neutralizer, 0-1 part of dispersant, 0-1 part of flatting agent, 0-1 part of defoamer, 2-5 parts of thickener, 1-5 parts of cosolvent and 10-30 parts of solvent. The fluorescent powder is adopted as a main luminous material, and the waterborne alkyd resin has high weatherability, so that the waterborne alkyd fluorescent paint can be obtained. The waterborne alkyd fluorescent paint is simple in preparation process and has excellent performance-cost ratio.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a water-based alkyd fluorescent coating. Background technique [0002] Fluorescent coatings are mainly used in architectural coatings, outdoor artificial landscapes, billboards, etc., and are a kind of coating with strong color and decoration. Ordinary fluorescent paints are solvent-based products with high VOC content, which is easy to cause harm to the environment and is not conducive to energy saving and emission reduction. At present, some cities in my country have issued restrictions on VOC, so the use of solvent-based fluorescent paints is also increasing. Most of them are restricted, and water-based coatings are less harmful to the environment and construction personnel due to their extremely low VOC content, and have therefore been vigorously promoted by the state. Waterborne alkyd resin paint has good weather resistance and excellent cost performance, and is also very s...
