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 minute. Then sequentially add butyl acrylate, ethyl ester, cyclohexanone and xylene and then stir, the reactant should eliminate stratification 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 environmentally friendly thinner, its main components are 55-65 parts of dioxyethylmethane, 8-12 parts of 120# solvent gasoline, 7-9 parts of xylene, 11-13 parts of absolute 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 invention adopts diethoxymethane as the main component, and the amount of benzene is very small, which is beneficial to labor protection and complies with the requirements of governments at all levels and enterprises and institutions to improve the working environment of laborers. And the versatility is obvious, it can dilute nitro paint series, alkyd paint series, acrylic paint series, epoxy paint series, polyurethane paint series, perchlorethylene paint series and acetal paint series, etc. At the same time, its production process is simple, and there is no waste water, waste residue discharge, and a small amount of gas volatilization in the production process, which meets the national emission standards.

Description

technical field [0001] The invention relates 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 damage the human body's circulatory system and hema...
