Problems solved by technology

The monomer reaction of water-based acrylic emulsion is not complete, and it is easy to remain in the product; after the film is formed, the hydrophilic group still remains in the coating film, so the water resistance is poor and the performance is average
As the product storage time prolongs and the temperature changes, the residual monomers will easily cause the viscosity of downstream products to change greatly during use, the product quality will be unstable, and the storage and transportation costs will be high and unsafe

Abstract

The invention discloses water-soluble styrene-acrylic acid solid resin and a preparation method thereof, and relates to the field of polyester. The method comprises the following steps: putting styrene, acrylic acid and other monomers into a continuous reactor to generate body polymerization reaction in a solvent system under the action of an initiator. The production cost of polyester obtained bythe preparation method is low, and the production process is safe and reliable. Automatic continuous production can be implemented, and the preparation method has a wide prospect. The market monopolyof foreign large enterprises can be broken.

Description

technical field [0001] The invention relates to the polyester field, in particular to a water-soluble styrene-acrylic solid resin and a preparation method thereof. Background technique [0002] The high volatiles in the original oleoresin products have a great impact on the environment and human health. In addition, in recent years, the national environmental protection monitoring has become more and more strict, and the people's environmental awareness has become stronger and stronger. Water-based inks, varnishes and The water-based paint market is getting bigger and bigger, and there are more and more varieties. Most of the market is water-based acrylic emulsion and a small amount of foreign water-based acrylic solid resin (high price). The monomer reaction of water-based acrylic emulsion is not complete, and it is easy to remain in the product; after the film is formed, the hydrophilic group still remains in the coating film, so the water resistance is poor and the perfo...
