Problems solved by technology

[0002] Ethylene glycol is an important organic chemical raw material, mainly used to produce alkyd resin, polyester, antifreeze, non-ionic surfactant, ethanolamine and explosives, etc. The demand for it in my country is very large. On the one hand, it is used to prepare ethylene glycol The disadvantages of alcohol are very obvious. It relies on petroleum resources, consumes a lot of water, and costs high. On the other hand, the amount of ethylene glycol used is very large, resulting in a large number of ethylene glycol waste. The treatment of ethylene glycol waste has always been a major problem for people. The application of ethylene glycol as a synthetic material in the production of alkyd resin has a great impact on the waterproof, weather resistance, and acid and alkali resistance of alkyd resin. How to apply ethylene glycol waste in the synthesis process of alkyd resin to Effective recycling of ethylene glycol waste can not only purify the environment and reduce pollution, but also turn waste into treasure and save a lot of petroleum resources

Abstract

The invention discloses an acrylic-acid-modified water-based alkyd resin and a preparation method thereof. The acrylic-acid-modified water-based alkyd resin is prepared from metaxylene, styrene, ethylene glycol waste, an initiator, isobutyl acrylate, n-butyl methylacrylate, methacrylic acid, dehydrated castor oil, phthalic anhydride, m-phthalic acid, trimethylolpropane, dimethylolpropionic acid, an antioxidant, a cosolvent, a neutralizer, paraxylene and water. The ethylene glycol waste is defective waste, can be derived from tobacco industry, textile industry, cosmetics and other industries, thereby greatly lowering the production cost of the product, solving the problem of treatment of ethylene glycol waste, cleaning the environment, changing waste into valuable substances and saving abundant petroleum resources. The product has the advantages of excellent water resistance, excellent weather resistance and excellent acid / alkali resistance. The method is simple in preparation process and convenient for operation.
