Embodiment 1

[0011] Take 60 parts of diethoxymethane, 10 parts of 120# solvent gasoline, 8 parts of xylene, 12 parts of absolute alcohol, 2 parts of glycol, 2 parts of butanol, 1 part of butyl acrylate, 2 parts of ethyl ester, cyclohexane Ketone 2 parts.

[0012] Preparation method: Put 120# solvent oil (99 parts), absolute alcohol, butanol (99 parts), glycol alcohol (99.8 parts), and diethoxymethane into the reaction kettle in sequence, and then stir for ten minutes. Then sequentially add butyl acrylate, ethyl ester, cyclohexanone and xylene and stir, the reactant should eliminate delamination and appear clear and transparent without mechanical impurities. After standing still for 2 hours, it should be the same as just after the reaction. Visual observation shows that a clear and transparent finished product without mechanical impurities is obtained.

Abstract

An environment-friendly diluent comprises the following main components: 55-65 parts of diethoxymethane, 8-12 parts of 120# solvent naphtha, 7-9 parts of dimethyl benzene, 11-13 parts of anhydrous alcohol, 2 parts of glycol, 2 parts of butanol, 1 part of butyl acrylate, 2 parts of ethyl ester and 2 parts of cyclohexanone. The environment-friendly diluent has the advantages that diethoxymethane is adopted as a main component, and the consumption of benzenes is extremely low, so that labor protection is facilitated, and the requirements of governments at all levels and all enterprises and public institutions for improving the working environment of labors at the present stage are met; the environment-friendly diluent is obvious in universality, and can be utilized for diluting lacquer paint series, alkyd paint series, acrylic acid paint series, epoxy paint series, polyurethane paint series, perchloroethylene paint series, acetal paint series and the like; meanwhile, the production technology is simple and conforms to the national emission standards, that is, no wastewater or slag is discharged and a small amount of gas is volatilized in the production process.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an environment-friendly diluent. Background technique [0002] At present, in various coating processes, most of the paint thinners use toxic solvents such as xylene, toluene and benzene as the main raw materials (the content generally exceeds 30 parts), and both producers and users are prone to frequent contact and make themselves Produce benzene poisoning. And it will cause air pollution and expand the scope of benzene poisoning. Benzene mainly comes from chemical raw materials widely used in architectural decoration, such as paints, wood varnishes, adhesives and various organic solvents. During the film-forming and curing process of the paint, volatile components such as formaldehyde and benzene contained in it will be released from the paint, causing pollution. The International Health Organization has classified benzene as a strong carcinogen. Long-term inhalation will da...
