Embodiment 1

[0021] A kind of preparation method of high-performance acrylic water-based resin is characterized in that comprising the steps:

[0022] 1) Grinding the solid acrylic resin into the fine powder that the 120-mesh sieve passes through, and set aside;

[0023] 2) In a stainless steel container, under mechanical stirring, add in order:

[0024] Water: 5%

[0025] Ethanol: 28%

[0026] Ethylene glycol butyl ether: 11%

[0027] Ammonia: 5%

[0028] Defoamer: 1%;

[0029] 3) Under mechanical stirring, slowly add 50% of solid acrylic powder resin to make it fully dispersed to a transparent viscous resin liquid, and pack it in a large barrel for paint making.

Abstract

The invention discloses a preparation method for high performance acrylic waterborne resin. The method is characterized by including: 1) grinding solid acrylic resin into fine powder able to pass through a 120-mesh sieve; 2) under mechanical stirring, adding water, ethanol, ethylene glycol butyl ether, ammonia water and a defoaming agent into a stainless steel container in order; 3) under mechanical stirring, adding solid acrylic powder resin slowly and making it fully dispersed into transparent and viscous liquid resin, and conducting packaging with a vat to make the product used for paint making. The preparation method provided by the invention has the advantages of simple process, good production stability, effectively shortened reaction time, stable product performance, and good economical efficiency. The acrylic waterborne resin prepared by the method is comparable with equal oil resin from the aspects of performance, appearance and cost, so that replacing oil paint by water paint becomes possible, and the safety and environmental problems of oily paint are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a preparation method of high-performance acrylic water-based resin. Background technique [0002] Acrylic resin has the characteristics of high gloss, good mechanical properties and weather resistance, and is an important raw material for making paints. Because the paint contains a large amount of organic solvents, contains toxic and harmful substances such as benzene, and is flammable, it is listed as a hazardous chemical. Therefore paint has three major shortcomings of danger, environmental pollution and harm to human health. Water-based paint is an important way to solve the three major shortcomings. Researchers in the coatings industry all over the world have been striving for water-based paints for decades. At present, there is still a contradiction between cost and performance, which has not been well resolved, so it cannot be widely used. [0003] ...
