Abstract

The invention relates to the field of a processing and treatment industry of wooden handicrafts and discloses flame-retarding coating for the wooden handicraft. Diatomite is added into high polymer resin and is smelted to form porous flame-retarding resin; the porous flame-retarding resin has excellent flame-retarding and heat-insulation performance and can be self-extinguished after being taken away from a fire source for 1 to 2 seconds; the thermal conductivity coefficient is low, the hydrophobic performance is strong and the construction is convenient; the flame-retarding resin can cope with dangerous fire disasters; a protection layer is formed on the surface of the wooden handicraft after flame retarding and an inner part is prevented from being damaged; bad influences on the servicelife of the wooden handicraft are not caused; the invention provides an effective way for improving the fireproof and flame-retarding performance of the wooden handicraft; a preparation process of thecoating is simple and energy saving and environmental protection are realized; the coating is environmentally friendly and has high utilization efficiency; the flame-retarding coating has the advantages of convenience for operation, safety and reliability, long service life and the like and is a technical scheme which is extremely worthy of being popularized and applied.

Description

technical field [0001] The invention belongs to the technical field of wooden crafts processing industry, and in particular relates to a flame-retardant coating for wooden crafts. Background technique [0002] Wood is the lignified tissue of plants capable of secondary growth, such as trees and shrubs. After the primary growth of these plants ends, the vascular cambium in the rhizome becomes active, developing bast outward and wood inward. Wood is the general term for plant tissues that develop inwardly from the vascular cambium, including xylem and parenchyma rays. Wood plays a great supporting role in human life. According to the different properties and characteristics of wood, people use them in different ways. Wooden handicrafts in the broad sense use various woods (including various bamboos) as the main raw materials, while wooden handicrafts in the narrow sense mainly use various woods as raw materials. Fine workmanship, simple design, different styles, natural co...
