Abstract

The invention provides a low-VOC stain-resistant formaldehyde-resisting interior wall latex paint and a preparation method thereof. The interior wall latex paint comprises the following components in parts by weight: 30-40 parts of Dow 3030 latex, 6-8 parts of Dow excellently-created E latex, 1.2-1.5 parts of a Dow coalescing agent, 0.3-0.5 part of hydroxyethyl cellulose, 0.01-0.02 part of a PH conditioning agent, 1.0-1.5 parts of a Rhodia freeze-thaw stabilizer FT-100, 0.1-0.2 part of a wetting agent, 0.8-1.0 part of a dispersing agent, 0.5-0.8 part of a foam killer, 20-25 parts of titanium dioxide, 4-5 parts of bergmeal, 12.5-17.5 parts of calcium carbonate, 0.2-0.3 part of a mould inhibitor, 0.1-0.2 part of a disinfectant, 0.5-0.8 part of a rheological additive, and 10-15 parts of water. The invention further provides a preparation method for the interior wall latex paint. The interior wall latex paint provided by the invention has the advantages that the content of VOC in indoor air is effectively reduced, the durability of indoor formaldehyde resolving is enhanced, and the stain-resistant performance of a latex paint coating wall is improved.

Description

technical field [0001] The invention belongs to the technical field of coatings, and particularly relates to a low-VOC stain-resistant and formaldehyde-resistant interior wall latex paint and a preparation method thereof. Background technique [0002] Indoor air quality has a very large impact on people's physical health, especially on children's health. One of the main causes of indoor air pollution is the organic volatiles released by the latex paint applied for interior decoration, of which formaldehyde is the main component of organic volatiles, so people are more cautious about the selection of latex paint used for interior decoration. The country has stricter quality control of interior decoration latex paint. In recent years, the General Administration of Quality Supervision and Quarantine of the People's Republic of China and the Ministry of Construction have issued a series of standards and regulations to control indoor air quality to protect people's health. At pr...
