Rubber wood high-performance decolorizing formula and decolorizing process

Abstract

The invention relates to a rubber wood high-performance decolorizing formula. The rubber wood high-performance decolorizing formula comprises the following components: a sodium chlorite solution, a sodium dodecyl benzene sulfonate solution, a hydrogen peroxide solution, a citric acid solution and a borax solution. After the rubber wood timber is improved for permeability and discolorized by utilizing the decolorizing formula and decolorizing method, the decolorizing depth is increased by 6 to 8 mm, the natural color of the rubber wood timber can be well maintained, and the clarity and attractiveness of the wood texture can be maintained. By virtue of the permeability improvement and decolorizing treatment, the color index of a board made of the rubber wood timber is improved, i.e. the brightness is high, the whiteness is high, the color difference is small, and the color is uniform. By virtue of the permeability improvement and decolorizing, the timber permeability can be effectively improved, paint can easily penetrate into the timber, so that great convenience can be brought to the coating of a product, the product types of the enterprises can be increased, and the economic benefit of the enterprises can be greater.

Description

technical field [0001] The invention relates to the technical field of high-efficiency decolorization treatment of rubber wood, in particular to a formula for high-efficiency decolorization treatment of rubber wood and a decolorization treatment process. Background technique [0002] Rubber wood has beautiful texture and moderate density, but because it contains a lot of polysaccharides, starch, tannic acid, and polyphenols, these chromophores that contain a lot of ether bonds, carbonyl groups, conjugated double bonds, acetyl groups, and benzene rings Organic matter, in the process of harvesting, transportation, storage, drying and mechanical processing, due to the action of oxygen, high temperature and high humidity environment, chemical discoloration will occur, accompanied by photodiscoloration and biological discoloration, which will cause poor visual effect on the surface of wood and result in a decline in product quality , reducing economic benefits.

Problems solved by technology

[0002] Rubber wood has beautiful texture and moderate density, but because it contains a lot of polysaccharides, starch, tannic acid, and polyphenols, these chromophores that contain a lot of ether bonds, carbonyl groups, conjugated double bonds, acetyl groups, and benzene rings Organic matter, in the process of harvesting, transportation, storage, drying and mechanical processing, due to the action of oxygen, high temperature and high humidity environment, chemical discoloration will occur, accompanied by photodiscoloration and biological discoloration, which will cause poor visual effect on the surface of wood and result in a decline in product quality , reducing economic benefits

[0003] The current treatment methods and existing problems for the decolorization of discolored rubber wood boards are as follows: (1) Single oxidation bleaching method: the board after treatment will return to color, the effect is short-lived, the gloss of the board after treatment is poor, and the treatment depth is not enough

[0004] (2) The decolorization of rubber wood panels by biological methods is still only in the laboratory research stage, and the cost is relatively high

[0005] (3) Treating with sodium hydroxide is a method commonly used in industrial production at present, but the disadvantage is that the treatment time is long, the waste water discharge is large, the labor cost is high, and the treatment effect is not good

This patent is suitable for blue stains, mildew, insect stains, black spots, etc. on the surface and center of veneer or bamboo chips, especially for recombined decorative materials, but the anti-mildew and anti-discoloration treatment effect on rubber wood panels is not good
