Abstract

The invention relates to sterilization and mould prevention water-based emulsion paint. The sterilization and mould prevention water-based emulsion paint is prepared from water, cellulose, a pH adjusting agent, a wetting agent, a dispersing agent, ground calcium carbonate, precipitated barium sulphate, sterilization and mould prevention active group introduced modified pure acrylic emulsion, a coalescing agent, a thickening agent and an antifreezing agent. The defects that a sterilization and mould prevention reagent needs to be additionally added to existing emulsion paint to prolong the storage period of the paint, hazardous substances of the sterilization and mould prevention reagent are prone to volatilize to harm the health of the human body, and the effective period of sterilization and mould prevention is short are overcome, and the advantages that the volatile sterilization and mould prevention reagent does not need to be additionally added, the sterilization and mould prevention effect is lasting, storage is stable, and the preparation method is simple are achieved.

Description

technical field

[0001] The invention relates to a bactericidal and mildew-proof water-based latex paint and a preparation method thereof, which are applied in the field of architectural water-based paints. Background technique

[0002] According to the "Tenth Five-Year Plan of the National Chemical Building Materials Industry and the 2015 Development Plan Outline", during the "Tenth Five-Year Plan" period, my country's urban housing construction will continue to develop at a construction rate of about 500 million square meters per year. The main task of the development of my country's coating industry Focusing on architectural coatings, the application of architectural latex paints in exterior wall decoration accounts for more than 60%.

[0003] In the existing production and preparation technology of latex paint, considering its production, storage stability and long-term weather resistance of the paint film, it is inevitable to add a certain amount of bactericidal and antif...
