Coated wood made of cedar wood

Abstract

Coating timber with Japan cedar wood as a raw material belongs to the technical field of wood plate production. The coating timber is produced through eight procedures, including, drying, material preparing, sanding, repairing, coating, re-coating, re-sanding and painting. The beneficial effects are that: the ultrafine Japan timber powder is used as the main raw material to repair the timber and serves as a contact medium of the timber and the coating, so that the coating material and the Japan cedar timber can be fully and easily integrated; the coating material is made into a primary coating material and a repeated coating material according to two proportions, the primary coating material controls the expansion of the annual rings, and the repeated coating material can enable the coating timber to keep the outer surface smooth and fine; the examination shows that the coating timber with the Japan cedar wood as the raw material has a fine and compact coating texture, strong flame retardancy, uniform coating, a strong anti-compact capability and a good waterproof effect, so that performances of the Japan cedar timber are not only improved, the application range of the Japan cedar timber is also increased greatly; the deserved economic value of the Japan cedar timber can be fully played, and conditions are created for the protection of the wild wood and forests.

Description

technical field [0001] The invention belongs to the technical field of wood board production, in particular to a coated wood material using cedar wood as a raw material. Background technique [0002] Due to the well-developed resin pipe diameter of cedar cedar, high oil content, large deformation of wood, serious warping and cracking during drying, and no corrosion resistance, when the temperature is high, it even spills oil and contaminates the surface of the material, resulting in poor paint and bonding performance; The texture of fir is obvious, and the color of early wood and late wood is inconsistent, so that it is difficult to cover with water-based paint, which affects the quality of wood products, so it is rarely used in furniture. At present, it is mainly used for building templates, ore pillars, boards, packing boxes, and matches. Rods, plywood, etc., or as a raw material for man-made fiberboards. [0003] But cedar, as a kind of fast-growing economic forest, is w...

Problems solved by technology

[0002] Due to the well-developed resin pipe diameter of cedar cedar, high oil content, large deformation of wood, serious warping and cracking when dry, not resistant to corrosion, even overflowing oil and contaminating the surface of the material when the temperature is high, resulting in poor paint and bonding performance; The texture of fir is obvious, and the color of early wood and late wood is inconsistent, so that it is difficult to cover with water-based paint, which affects the quality of wood products, so it is rarely used in furniture. At present, it is mainly used for building templates, ore pillars, boards, packing boxes, and matches. Rods, plywood, etc., or as a raw material for man-made fiberboard

[0003] However, as a kind of fast-growing economic forest, cedar is widely planted in most mountainous areas of our country. Due to the limitation of its application field, its due economic value is not fully exerted; it indirectly causes the destruction of other precious tree species or wild wood
