Abstract

Disclosed is a producing and processing method of toon carbonized wood coating timber. The method comprises the steps of material preparation, grinding of first time, repairing, grinding of second time, primary coating, grinding of third time, recoating, grinding of fourth time and paint spraying. The method has the advantages that ultrafine micro toon carbonized wood powder is adopted as main raw materials to repair the timber, and used as contact media of wood and coatings, meanwhile, heavy calcium carbonate, white emulsion, epoxy acrylate, glutinous rice flour, photoinitiator and curing agents are used for manufacturing coating materials, and the coating materials are fine, smooth, moistened, strong in attachment force and resistant to wear and contamination; the coating materials are divided into primary coating materials and recoating materials, absorption of toon carbonized wood on water in the coating materials can be reduced, and the outer surface of the coating timber is kept smooth and fine; through inspection, the coating structure is fine, smooth and compact, the flame retardant property is high, coating is even, the impact resisting performance is high, wear and contamination are resisted, the waterproof effect is good, the performance of the toon carbonized wood is improved, the toon carbonized wood is beautified, and quality and economic value are improved.

Description

technical field [0001] The invention belongs to the technical field of wood board production and processing, in particular to a production and processing method of red toon charred wood coated wood. Background technique [0002] Due to the relatively low surface hardness of wood and poor wear resistance, external forces are more likely to cause surface damage. After painting, the surface hardness of wood can be improved to a certain extent, thereby reducing the damage of external force. The dense coating formed after painting can prevent the movement of moisture in wood products due to changes in environmental temperature and humidity, thereby avoiding deformation and cracking of wood due to expansion or shrinkage. After the wood surface is painted, the coating film protects the wood product from deformation due to changes in external humidity, minimizing damage. At the same time, for wood products made of inferior wood, due to the protection of paint, its own defects (wo...
