Abstract

The invention provides water-based woodware anti-formaldehyde varnish and a preparing method thereof. The water-based woodware anti-formaldehyde varnish is prepared from, by weight, 60-80% of anti-formaldehyde acrylic emulsion, 0.4-1% of antifoaming agent, 0.5-1.5% of wetting agent, 0.5-1% of flatting agent, 2-3% of photocatalyst, 0.2-1% of thickening agent, 3-8% of coalescing agent, 0-0.5% of bactericide, 5-35% of water, and an appropriate amount of pH conditioning agent. The water-based woodware anti-formaldehyde varnish is excellent in physico-chemistry property, good in workability, and can effectively remove formaldehyde in furniture boards, tackifier and air, wherein the formaldehyde removal rate is larger than 90%; besides, formaldehyde in air can be sustainably and effectively removed. In the using process, the water-based woodware anti-formaldehyde varnish does no harm to the health of constructors, and thus the water-based woodware anti-formaldehyde varnish is a water-based and environment-friendly product.

Description

technical field

[0001] The invention belongs to the technical field of materials, and in particular relates to a water-based formaldehyde-resistant varnish for woodware and a preparation method thereof. Background technique

[0002] Among the indoor harmful volatiles, formaldehyde, which was identified as a carcinogen by the International Agency for Research on Cancer in 1995, is the most stubborn, and its incubation period can reach 3-15 years, endangering people's health for a long time. Formaldehyde in indoor air mainly comes from free formaldehyde released from interior decoration materials. The release sources mainly include wood-based panels and their products, furniture, adhesives, carpets and wallpapers, etc.

[0003] Water-based wood coatings are currently recognized as the most environmentally friendly coating type, featuring low volatile organic compound content (VOC), which greatly reduces the use of organic solvents. In the prior art, there are water-based wood...

Examples

Embodiment 1
