Abstract

This invention relates to a special material of latex paint talc powder, which is formed by the following components according to the percentage by weight: 26-29% of 325-2500 mesh talc, 1.5~2% film promoter agent, 0.5-0.7% of wetting dispersant, 0.2-0.4% of preservative, 0.2~0.4% of defoamer, 10-12% of color filler, 38-41% of styrene-acrylic emulsion, 18-20% of water. Talc is produced from talc ore with high brightness and low heavy metal, ensuring lead, chromium, cadmium and other heavy metals not surpassing the standard. Base material is not toxic, and agent has high boiling point without solvent and water dispersion additives, which meet the standard of environment-protective latex paint. Its curing process does not release toxic solvents, reducing pollution, conserving resource and energy, and benefiting human health and survival.

Description

technical field [0001] The invention relates to the field of powder technology, mainly the application of talcum powder in latex paint for interior and exterior walls. Background technique [0002] The rapid growth of my country's economy has provided good development opportunities for architectural coatings, especially as the 2008 Beijing Olympic Games is approaching and the Shanghai World Expo will be held in my country. Various competition venues, exhibition halls, apartments, buildings and other buildings are being constructed one after another. The urban landscape is being beautified, which not only provides rare opportunities and a broad market for interior and exterior wall latex paint, but also puts forward higher requirements for interior and exterior wall latex paint. However, the quality of many interior and exterior latex paints is not up to standard, such as VOC volatiles exceeding the national standards, and heavy metals exceeding t...
