Problems solved by technology

This method only solves the problem that the wood texture and density are close to that of mahogany, and the color of furniture needs to be painted with mahogany paint, which is not realistic enough; (3) The technology of birch painting imitation mahogany is to paint birch products with imitation mahogany paint, which is mainly black. Ginseng is red, with a little golden color
(4) Polymer material molding imitation mahogany technology is molded with 64% unsaturated polyester, 30% talcum powder, 3% methyl ethyl ketone, 3% cobalt naphthenate and glass fiber cloth. Paint imitation mahogany resin, which lacks the sense of real wood; (5) Inorganic material molding imitation mahogany technology is 50 parts of magnesium chloride, 70 parts of magnesium oxide, 14 parts of sawdust, 4 parts of hemp wool, 3 parts of potting agent, and 1 part of modifier. 40 parts of water and 40 parts of water are made by pouring, lacking the sense of solid wood

Abstract

The invention discloses a technology for performing high-temperature oxygen deficit treatment on hardwoods for obtaining an artificial functional rosewood. The technology is characterized in that the hardwoods of which textural features are similar to those of rosewoods are used as materials; the appearance color of the hardwoods can be in a color space distribution feature range of color parameters of rosewood type timbers after the hardwoods are subjected to high-temperature oxygen deficit and micropore treatment; meanwhile, the gas-phase adsorption performance of the timbers is improved through the high-temperature oxygen deficit and micropore treatment, so that harmful gases such as formaldehyde, benzene and xylene can be adsorbed, and a function of purifying air can be realized. The functional rosewood simulation technology has the advantages that the hardwoods have vivid appearances, the production cost is low and the efficiency is high, and products do not contain harmful substances.

Description

technical field [0001] The invention belongs to the manufacturing process of furniture and building decoration raw materials, and is a process of imitating functional mahogany by anoxic and high-temperature treatment of hard miscellaneous wood. The chemical treatment enhances the gas phase adsorption performance, and can adsorb harmful gases such as formaldehyde, benzene, xylene, etc., so that it has the function of purifying the air. Background technique [0002] Existing imitation mahogany technology lacks sense of reality and has no functionality. (1) Paulownia wood imitation mahogany dyeing technology is to dye the veneer used for furniture veneer, using 1.5% NaCl, 0.5% dye, 2% acetic acid, 0.1% penetrant, and temperature 90°C, dyeing time 4h. The color and luster of this method is uneven and not firm, and only one layer of the surface is not real enough; (2) The imitation mahogany treatment technology of Quercus qinggang is to soak Quercus qinggang in hot water at a t...
