Abstract

The invention relates to the technical field of anti-aging agents for paint, in particular to an anti-settling agent for water-based baking paint as well as a preparation method and an application of the anti-settling agent. The anti-settling agent for the water-based baking paint is prepared from raw materials in parts by weight as follows: 50-200 parts of monohydric alcohol, 10-70 parts of polyol, 50-150 parts of phosphorus pentoxide, 50-150 parts of metal saponated matter, 0.5-2 parts of an antioxidant, 20-250 parts of an organic amine neutralizer and 100-300 parts of a solvent. The anti-settling agent for the water-based baking paint can solve the problems of precipitation and caking of filler in a water-based baking paint system, is simple to apply, good in anti-setting effect and effective as well for the large-density filler, and has no obvious influence on system viscosity.

Description

technical field [0001] The invention relates to the technical field of coating anti-settling agents, in particular to an anti-settling agent for water-based baking varnish coatings and a preparation method and application thereof. Background technique [0002] With the continuous acceleration of the global industrialization process, the consumption of petrochemical raw materials continues to increase, and the atmospheric emissions have increased sharply, resulting in environmental degradation. Generally, solvent-based coatings contain nearly 50% organic volatiles. The annual output of such coatings in my country is about 1 million tons. , the total global production is about 10 million tons, and there are millions of tons of organic volatiles. These organic volatiles are completely released into the atmosphere during the use of coatings. Many volatiles are photoactive substances, which destroy the ozone layer and cause ultraviolet radiation. Radiation has strengthened, deterio...
