Problems solved by technology

[0004] At present, in the patents on the preparation method of acrylic emulsion used for humidity-adjusting coatings, most of them use hydrophilic monomers containing hydroxyl, carboxyl, and amide groups, cellulose, and potato starch to graft and modify acrylic emulsion, so that Acrylic emulsion has the function of regulating humidity, and these methods are either costly or complicated; and using urea and hydroxyethyl urea to modify acrylic emulsion is not only simple in process but also has a good function of regulating humidity. In addition, there is no such method in the prior art. There are reports about urea-modified acrylic emulsion to change the humidity control performance, this invention will use urea or hydroxyethyl urea to modify the acrylic emulsion to make up for this vacancy, so that it has the function of humidity control

Abstract

The invention relates to an acrylic emulsion, and more particularly to an interior wall humidity controlling styrene-acrylic emulsion and a preparation method thereof. According to the present invention, an acrylic emulsion is modified with urea and hydroxyethyl urea; the process is simple, and the modified acrylic emulsion has an excellent humidity controlling function and is an interior wall styrene-acrylic emulsion which is excellent in humidity controlling performance and high in scrubbing resistance. The emulsion is prepared from the following raw materials: distilled water, an anionic emulsifier, a nonionic emulsifier, styrene, alkyl acrylate, unsaturated hydrocarbyl acid, acrylamide, a hydroxyl-containing acrylate monomer, a wetting agent, a crosslinking monomer, an initiator, an oxidizing agent and a reducing agent.

Description

Technical field: [0001] The invention relates to an acrylic emulsion, in particular to a styrene-acrylic humidity-adjusting emulsion for interior walls and a preparation method thereof. Background technique: [0002] With the development of the economy, people began to pursue better and better living environment. The relative humidity of the air is an important parameter closely related to people's life and production. If the relative humidity in the room is too high or too low, it will affect the normal life of human beings. Production and life, and the most suitable relative humidity is between 40 and 60%. Humidity-adjusting coatings are of great help to both the dryness in the north and the humidity in the south, and have a good application prospect. [0003] At present, the method of preparing humidity-adjusting coatings is mainly to start from the aspects of polymer film, pigment and filler, and production technology, and compound the modified acrylate emulsion with po...
