[ background of the invention ]

Glaze is a translucent to transparent pigment colorant for woodware, and is formed by dissolving resin in an organic solvent, and the used organic solvent can volatilize into the air in the film forming process and cause harm to the environment and human health. The traditional glaze also has the problems of low drying speed, poor transparency and difficult coloring. The UV glaze mainly comprises oligomer, photoinitiator, reactive diluent and other auxiliary agents, and has the advantages of short curing time, low curing temperature and low volatile component. However, such products generally have the disadvantage of poor flame retardancy, are extremely flammable when exposed to fire, and are prone to property damage and personal safety hazards. Therefore, a UV glaze with good flame retardant property is needed to solve the defects of the existing products.
