Description

technical field

[0001] The invention belongs to the field of environment-friendly paints, and particularly relates to a high-gloss environment-friendly paint for woodware and a preparation method thereof. Background technique

[0002] At present, the wood paints used for indoor furniture painting in my country are mainly solvent-based paint systems, mainly including nitro, alkyd, and polyurethane. Among them, polyurethane two-component wood paint has been widely used in the field of wood paint due to its high hardness, good toughness, and excellent water and oil resistance. However, with the concept of green and environment-friendly home being put forward, the problem that solvent-based coatings will generate a large amount of organic volatiles during the production and use process has attracted more and more consumers' attention. The emission of VOC (Volatile Organic Compound) produced by solvent-based paint products has become one of the important indicators for measuring...
