Paint coating thinner

Abstract

The invention relates to a paint coating thinner. The paint coating thinner comprises the following components in percentage by weight: 20 to 25 percent of acetic ether, 20 to 25 percent of ethyl ester and butyl ester, 2 to 5 percent of ethyl cellosolve, 3 to 5 percent of silicon oil, 5 to 8 percent of butanol, and the balance of ethanol. Preferably, the content of ethyl cellosolve is 4 percent. The paint coating thinner does not contain harmful substances such as benzene, so that the paint coating thinner is pollution-free to the environment, does not have toxic effect on human bodies, can be used as a chlorinated polyvinyl chloride paint, a nitrate paint, an amino resin paint, an alkyd resin paint, an oil-based paint, an acrylic resin paint, an polyester resin paint, an epoxy resin paint and the like, and has high physical and chemical properties.

Description

technical field [0001] The present invention relates to a thin material, especially a thin material that does not contain harmful substances. Background technique [0002] At present, the paint thinners on the market are basically formulated with xylene and toluene as the main body, and their aromatic hydrocarbon content is high and the toxicity is high. Long-term exposure can cause acute or chronic poisoning. Due to decoration and other purposes, about 25 tons of benzene-based solvents are released into the air every year in my country. At present, there are two main methods to control benzene pollution in my country: one is to install air purification devices and use catalytic combustion method; the other is to use activated carbon adsorption method. However, these two methods are for the purpose of treatment after benzene pollution has occurred. In order to find new methods, China Environmental Protection Corporation and other scientific research units and research ...

Problems solved by technology

However, because its products are composed of five raw materials, raffinate oil No. 120 or No. 200, butyl acetate, ethyl acetate, acetone, and ethanol, it is only suitable for perchloric paint and amino paint in eighteen types of paints. Thinners for fourth and fifth types of paints such as alkyd paints

Secondly, the main true solvent butyl acetate in its products is used in a large amount and the cost is relatively high
