Coating timber with Chinese fir wood as raw material

Abstract

The invention discloses coating timber with Chinese fir wood as a raw material, and belongs to the technical field of wood-based panel production. The coating timber is obtained through the eight procedures of drying, material preparing, sanding, repairing, coating, recoating, secondary sanding and spray coating. The coating timber has the advantages that the timber is repaired with ultra-thin fine Chinese fir powder as a main raw material and a contact medium of the timber and paint, and the paint and Chinese fir can be easily and fully integrated; the paint is made into primarily-coating paint and secondarily-coating paint according to two proportions, the annular ring expansion is controlled through the primarily-coating paint, and the outer surface of the coating timer can be kept smooth and fine through the secondarily-coating paint; through detection, the coating timber is fine, smooth and compact in coating structure, strong in flame retardant property, uniform in coating, high in impact resistant capacity, resistant to scraping and pollution, good in waterproof effect and capable of not only improving performance of the Chinese fir but also greatly enlarging the application range of the Chinese fir; the due economic value of the coating timber can be brought into full play, and conditions are created for protecting wild timber and forests.

Description

technical field [0001] The invention belongs to the technical field of wood board production, in particular to a coated wood made of fir wood. Background technique [0002] Due to the well-developed resin pipe diameter of fir, high oil content, large deformation of wood, serious warping and cracking when dry, not resistant to corrosion, and even overflowing oil and pollution on the surface of the material when the temperature is high, resulting in poor paint and bonding performance; The texture 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 formwork, ore pillars, boards, packing boxes, matchsticks, Plywood, etc., or as a raw material for man-made fiberboard. [0003] However, fir, as a fast-growing economic forest, is widely planted in most mountainous areas of our country. ...

[0002] Due to the well-developed resin pipe diameter of fir, high oil content, large deformation of wood, serious warping and cracking when dry, not resistant to corrosion, and even overflowing oil and pollution on the surface of the material when the temperature is high, resulting in poor paint and bonding performance; The texture 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 formwork, ore pillars, boards, packing boxes, matchsticks, Plywood, etc., or as a raw material for man-made fiberboard

[0003] However, Chinese fir, as a fast-growing economic forest, is widely planted in most of the mountainous areas of my country. Because of the limitations of its application field, its due economic value is not brought into full play; it indirectly causes the destruction of other precious tree species or wild wood
