Problems solved by technology

And usually the smell of paint thinner is unpleasant, which can easily cause human discomfort
[0004] Existing benzene-containing thinners have strong dissolving ability and are harmful to human health, while benzene-free thinners tend to whiten the paint film during spraying, dry too fast, have poor leveling, poor effect and are not environmentally friendly

Abstract

The invention relates to an efficient and environmentally-friendly paint diluent and a preparation method thereof. The paint diluent comprises ethyl acetate, butyl acetate, ethanol, acetone, dichloromethane, dichloroethane, ethylene glycol monoethyl ether acetate, cyclohexanone, tetrabutyl orthosilicate, an ethyl cellosolve, methyl isopropyl ketone, turpentine and an aromatic. The preparation method comprises the following steps: mixing the ethyl acetate, butyl acetate, ethanol, acetone, dichloromethane, dichloroethane, ethylene glycol monoethyl ether acetate, cyclohexanone, methyl isopropyl ketone and turpentine, adding an acid-base regulator to regulate the pH value to 5, performing stirring at 50-60 DEG C for 1-2 h, adding the tetrabutyl orthosilicate, the ethyl cellosolve and the aromatic, performing sufficient stirring, and cooling the obtained mixture to room temperature. The efficient and environmentally-friendly paint diluent has the advantages of good leveling property after being sprayed, no scaling, freeness of substances harmful to human bodies, and effectiveness in improvement of the smell generated after paint spraying by adding aromatic hydrocarbon for improving thesmell.

Description

Technical field [0001] The invention belongs to the field of chemical engineering materials, and specifically relates to a high-efficiency environmentally friendly paint thinner and a preparation method thereof. Background technique [0002] Paint thinner is a kind of liquid solvent with good miscibility with resin added in order to reduce resin viscosity and improve its process performance. Thermosetting resin in paint coating needs to add diluent to reduce its viscosity and facilitate further processing. These thinners are actually All organic solvents are cheaper than resins, so they also play a role in reducing processing costs. [0003] Previous paint thinners were more toxic, and their main components contained toluene and xylene. Toluene and xylene would have an adverse effect on the human hematopoietic system. Long-term exposure to paint thinner will cause a decrease in white blood cells and platelets (which will kill white blood cells), and may lead to aplastic anemia, or...
