Abstract

The invention belongs to the technical field of coating material diluents, and provides a coating material diluent containing a solvent not participating in a photochemical reaction. The coating material diluent comprises the following components in parts by weight: 30-40 parts of tert-butyl acetate, 20-30 parts of methyl acetate, 10-15 parts of dimethyl carbonate, 8-10 parts of propylene glycol diacetate and 10-15 parts of ethylene glycol tert-butyl ether. The invention further provides a preparation method and application of the coating material diluent containing the solvent not participating in the photochemical reaction. According to the invention, the coating material diluent disclosed by the invention is a low-toxicity environment-friendly coating material diluent, does not containharmful substances such as benzene, halogenated hydrocarbon, formaldehyde and the like, is beneficial to labor protection, does not participate in a photochemical reaction after volatilization, does not cause photochemical pollution, effectively reduces VOC emission and plays a role in protecting the environment; and the cost of the coating material diluent is lower than that of a benzene-containing diluent, and the universality is obvious.

Description

technical field [0001] The invention relates to the technical field of paint thinners, in particular to a paint thinner containing a solvent that does not participate in photochemical reactions, a preparation method and application thereof. Background technique [0002] Thinners for coatings are composed of various solvents and are mainly used to adjust the viscosity of coatings so that they can be applied by brushing, spraying or dipping. They are indispensable products in the coatings industry. my country's paint output has become the first in the world, and a large market has been formed for paint thinners, with an output of at least 5 million tons. [0003] Solvents in coatings will have many impacts on the environment, including the release of solvents during coating production, the release of solvents and toxic substances during coating construction, the release of solvents during the use of coatings and during paint stripping, etc., which have caused environmental pol...
