Problems solved by technology

[0007] Compared with wood, because bamboo has a higher starch content, even bamboo products that have been treated with general preservatives are more likely to be attacked by discoloration bacteria during outdoor use, which severely limits their scope of use and affects the export of their products. Urgent problems to be solved in bamboo processing industry
[0008] Chinese patent publication CN1989814A discloses the use of sodium pentachlorophenate as an anti-mold component of bamboo and rattan products. Although the effect is better, it is prohibited to use in the world due to the high toxicity of sodium pentachlorophenate to humans.

Abstract

The invention relates to a water-soluble triazole antiseptic anti-discoloration insect repellent composite for timber and bamboo wood as well as a preparation method and application thereof. Based on the total weight of the composite, the composite comprises the following components in percentage by weight: 3-8% of triazole compound, 24-48% of organic solvent, 24-40% of cosolvent, 3-10% of N-(2-benzimidazolyl)-methyl carbamate hydrochloride, 0-10% of prochloraz, 0.1-0.8% of esbiothrin insecticide and the balance of water, wherein the triazole compound is propiconazole, tebuconazole, cyproconazole or any combination of propiconazole, tebuconazole and cyproconazole. The composite can be used for processing timber and bamboo wood or timber and bamboo wood products indoor and outdoor. In the processing method, a vacuum pressurization or normal-pressure dipping method are used so that the processed timber and bamboo wood or timber and bamboo wood products have the antiseptic, anti-fungus discoloration and mothproof properties.

Description

technical field [0001] The present invention relates to a class of water-soluble triazole wood and bamboo anticorrosion, anti-discoloration and insect repellent composition, its preparation method and application. The composition of the present invention is suitable for anti-corrosion, anti-discoloration and / or insect prevention of indoor and outdoor wood and bamboo or wood and bamboo products deal with. Background technique [0002] Wood preservative treatment can improve the durability of wood. Compared with CCA (chromium copper arsenate), ACQ and copper azole wood preservatives, wood preservatives containing organic components are more environmentally friendly. After the preservative wood treated with this preservative reaches the service life, the organic matter contained in it can be Natural decomposition will not cause pollution to the environment, and will not cause problems in the recycling and disposal of solid waste. [0003] At present, Australia, New Zealand an...
