A compound type copper compound preservative for masson pine wood and its preservative method

Abstract

The invention discloses a compound type copper compound preservative for masson pine wood and a preservative method. The preservative is composed of the following raw materials in mass percentages: 0.05%-0.50% of 8-hydroxyquinoline copper and 0.05% of tebuconazole ~0.50%, 5.00%~20.00% glacial acetic acid, 5.00%~20.00% didecyldimethylammonium chloride, and the balance is water; the preservative method includes steps such as preservative impregnation and vacuum drying of masson pine wood. The compound copper compound preservative of the present invention has excellent broad-spectrum bactericidal properties, loss resistance and bacteriostatic ability, is low in price, and has low toxicity to humans and animals. The anti-corrosion method of the present invention can significantly improve the control effect of masson pine wood on decay bacteria, blue stain bacteria and mold, and significantly reduce the damage value of wood infected by fungi, and has simple process, convenient operation and low energy consumption, which can effectively reduce production costs. cost.

Description

technical field [0001] The invention belongs to the technical field of wood processing, and in particular relates to a compound type copper compound preservative for masson pine wood and a preservative method. Background technique [0002] my country uses 5% of the world's forest area and 3% of its forest reserves to support the growing demand for timber consumption, which accounts for 20% of the world's population. Forest resources are under enormous pressure and the security situation is very severe. In 2017, commercial logging of natural forests will be completely stopped in my country. Timber production will decrease sharply, and the gap between timber supply and demand will continue to increase. Fast-growing plantation timber will be my country's main timber raw material in the future. Masson pine is one of the main timber and afforestation tree species in my country, but masson pine wood is very susceptible to blue stain and mold infection during storage, resulting in ...

AI Technical Summary

Problems solved by technology

However, there are deficiencies in oil-borne preservatives. The main reason is that their organic solvents generally do not have corrosion resistance or have low corrosion resistance, and only serve as a carrier, and the price of organic solvents is relatively expensive, resulting in high processing costs. All solvents are flammable substances, which requires stricter fire prevention measures and good ventilation equipment in the anticorrosion treatment factory

However, water-borne preservatives using water as a carrier can effectively overcome the above-mentioned shortcomings, but there are few research reports on the use of 8-hydroxyquinoline copper for the preparation of water-borne preservatives in the prior art
