Embodiment Construction

[0012] The main components of the present invention are diethoxymethane 60%, 120# solvent gasoline 10%, xylene 8%, ethanol 12%, ethylene glycol 2%, butanol 2%, butyl ester 2%, ethyl ester 2%, Cyclohexanone 2%.

[0013] Preparation method: 120# solvent oil (99% content), ethanol, butanol (99%), glycol alcohol (99.8%), diethoxymethane are sequentially dropped into the reactor, then stirred for ten minutes . Then add butyl ester (99.88%), ethyl ester (99.8%), cyclohexanone (99.6%) and xylene in sequence, and then stir, the reactant should eliminate delamination and be clear and transparent, without mechanical impurities. After standing for 2 hours, it should be the same as just after the reaction. Visual observation shows that the finished product is clear and transparent without mechanical impurities.

Abstract

The invention discloses a green environment-friendly diluent which mainly comprises the following components: 55-65% of dioxo ethyl methane, 8-12% of #120 solvent gasoline, 7-9% of dimethylbenzene, 11-13% of ethanol, 2% of ethylene glycol, 2% of butanol, 2% of butyl ester, 2% of ethyl ester and 2% of cyclohexanone. The green environment-friendly diluent adopts dioxo ethyl methane as the main component, and the use amount of benzene is small, so that the working security is facilitated, and the requirements on working environment improvement of departments and enterprises are met; and moreover the green environment-friendly diluent is remarkable in university, and the nitrolacquer paint series, the alkyd paint series, the crylic acid paint series, the epoxy paint series, the polyurethane paint series, the vinylidene chloride paint series, acetal paint series and like can be diluted; and meanwhile the production process is simple, and the production process is free of waste water and waste slag discharge and has small amount of gas volatilization, so that the national discharge standard is met.

Description

technical field [0001] The invention relates to a green environmental protection diluent. Background technique [0002] At present, in various coating processes, most of the coating thinners use toxic solvents such as xylene, toluene and benzene as the main raw materials (the content is generally more than 30%). 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 coatings, wood varnishes, adhesives and various organic solvents. During the film forming and curing process of the coating, the volatile components such as formaldehyde and benzene contained in it will be released from the coating, causing pollution. The International Health Organization has designated benzene as a strong carcinogen. Long-term inhalation will damage the body's circulatory system and hematopoietic function, leading to leukemia. In addition, women are...
