Problems solved by technology

[0003] At present, there are still many paints on the market, which have high VOC content. After painting, the room still needs a long time to dissipate before being able to move in. The VOC contained will have a great impact on the human body and the environment.
In addition, some coatings have poor stain resistance, and these coatings cannot meet people's demand for high-end functional coatings

Abstract

The invention discloses an acrylic emulsion with low content of VOC (volatile organic chemical). The acrylic emulsion is prepared from the following components in parts by weight: 20.76 to 42.8 partsof core pre-emulsion A, 10.7 to 23.5 parts of shell pre-emulsion B, 0.66 to 3.1 parts of emulsifier, 0.28 to 1.3 parts of initiator, 0.1 to 0.6 part of buffer agent, 0.08 to 0.3 part of reducing agentand 40 to 60 parts of water. The acrylic emulsion has the advantages that by selecting the polymerizing monomers and improving the synthesizing technique and crosslinking technique, the waterborne acrylic resin emulsion with high property is synthesized; by reducing the usage amount of the emulsifier in polymerizing, the influence to the appearance of a coating film by the environment temperatureand humidity is relieved, and the filming characteristic of the emulsion is improved; by selecting the polymerizing monomers with excellent property, the polymerizing monomers are grafted onto the macromolecule chain of the acrylic emulsion, the problems of low fullness and low luster in the waterborne coating film are solved, the high-property coating is prepared, and the application field is expanded; by adding the polymerizing organosilicone monomer, the polymerizing organosilicone monomer is grafted onto the macromolecule chain of the acrylic emulsion, and the water-resistant whitening property of the coating film is improved.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to an acrylic emulsion with low VOC content, a synthesis method thereof and an architectural coating made from the acrylic emulsion with low VOC content. Background technique [0002] Coating is a chemical product with convenient construction and affordable price. Any coating that uses water as a solvent or dispersion medium can be called water-based coating. Water-based coatings can not only have a decorative effect, decorate the surface of buildings and machinery, but also have certain functions, such as anti-corrosion, anti-acid, anti-static, anti-aging, etc., which can prevent the surface of appliances from rusting and prolong their service life. With the development of coatings, coatings are gradually developing in the direction of functionality and environmental protection. [0003] At present, there are still many paints on the market with high VOC content. It still takes a...
