Abstract

The invention discloses an environmental-friendly exempt solvent which is prepared from the following components in parts by mass: 8-18 parts of tert-butyl acetate, 40-53 parts of dimethyl carbonate, 5-7 parts of methyl acetate and 23-30 parts of n-butyl acetate. The environmental-friendly exempt solvent disclosed by the invention is free of benzene, is beneficial to labor protection, is somehow low in cost when compared with that of benzene-containing diluents, is remarkable in universality, and is capable of diluting a nitrolacquer series, an alkyd paint series, an acrylic paint series, an epoxy paint series, a polyurethane paint series, a vinylidene chloride paint series, an acetal paint series and the like. The invention further discloses a preparation method of the environmental-friendly exempt solvent. The preparation method is simple in production process, free of wastewater or waste residue discharge in the production process, and small in gas volatilization which meets national discharge standards. Compared with conventional diluents, the environmental-friendly exempt solvent has the effects that a paint film on the surface of a product or a dried paint film can be relatively good in viscosity and the surface of the paint film can be relatively smooth when compared with that of a film formed by the benzene-containing diluents, and moreover relatively good moisture resistance can be achieved in the construction process.

Description

technical field [0001] The invention relates to an environment-friendly exempt solvent and a preparation process thereof, which are used for diluting various industrial paints, such as alkyd, phenolic, polyurethane, acrylic, epoxy, fluorocarbon and chlorinated rubber. Background technique [0002] Most of the exempt solvents currently on the market contain xylene, toluene and benzene, as well as toxic and harmful solvents such as chemical and pharmaceutical solvents. Both producers and users are prone to frequent exposure to benzene poisoning and air pollution. At present, the diluents of various high-grade industrial paints in the market are mainly specially formulated for use, and their general performance is poor, which increases the trouble of use. With the rise of China's manufacturing industry, China's machinery and equipment and other products export trade has become normalized, and export commodities must pass the commodity inspection of SGS.
