Problems solved by technology

However, due to housing renovation or new furniture replacement, the indoor formaldehyde content often exceeds the standard, especially now that there are whole rental apartments. In order to save time and cost, some businesses often rent out newly renovated apartments and new houses, causing serious health problems and adverse events. Good social impact. At present, water-based wood coatings are gradually expanding their market share in the home improvement market due to their excellent low VOC and wood protection properties.

Abstract

The invention belongs to the technical field of coating preparation, and particularly relates to water-based coating for wooden ware. The water-based coating for the wooden ware comprises 80-92 partsof polyethylene wax emulsion, 0.05-0.2 part of leveling agents, 1-2 parts of butyl glycol, 2-6 parts of coalescing agents, 0.1-0.2 part of bactericides, 0.1-0.2 part of mildew preventives, 0.1-0.3 part of defoaming agents, 0.2-0.5 part of leveling agents, 5-15 parts of formaldehyde-resistant catalysts and an appropriate quantity of deionized water. The formaldehyde-resistant catalysts are platinum / multi-valence-state manganese oxide-cerium dioxide complexes. The water-based coating for the wooden ware has the advantages that the wooden ware can be protected by the water-based coating, and effects of removing formaldehyde can be simultaneously realized by the water-based coating.

Description

technical field [0001] The invention relates to the technical field of paint and paint preparation, in particular to a water-based wood paint and a preparation method thereof. Background technique [0002] Woodenware is a very wide contact object in people's life. For woodenware, it is inevitable to mention formaldehyde. Formaldehyde, also known as formaldehyde, has a chemical formula of HCHO. Formaldehyde is a colorless substance with a strong pungent smell. Gas is a volatile organic compound. Formaldehyde is used to produce urea-formaldehyde resin and phenolic resin. Formaldehyde and urea are mixed in a certain molar ratio to form urea-formaldehyde resin. It is widely used in various wooden furniture for new house decoration. Therefore, formaldehyde is also One of the most common pollutants in indoor air, it is harmful to human health, can cause adverse effects on the respiratory system, and even cause cancer. The World Health Organization guidelines stipulate that the co...
