Problems solved by technology

Although natural products have many advantages, most natural product compounds have complex structures, are difficult to synthesize or the synthesis cost is too high, and have no use value. Most of them are unstable to light, or are extremely volatile, and usually cannot be used directly as protective agents.

Abstract

The invention discloses a wood or bamboo rot-proof processing method, comprising the following steps: soaking the wood, stewing the bamboo, and then steaming the bamboo. The invention has simple operation process, good controllability, low cost, easy industrialization and wide application prospect, and requires no complex chemical treatment and expensive equipment.

Description

technical field [0001] The invention relates to a mildew-proof and anti-corrosion treatment method for wood or bamboo, in particular to a mildew-proof and anti-corrosion treatment method for wood or bamboo. Background technique [0002] Because wood and bamboo contain a lot of starch, sugar, protein and other salts, their natural durability is poor, and they are easy to cause insects and mildew. The annual loss of wood and bamboo due to decay and insects accounts for about 10% of the world's wood and bamboo production. Therefore, the protection of wood and bamboo is of great significance for building a resource-saving bamboo industry. However, the protection of wood and bamboo is a weak link in the utilization of wood and bamboo in my country. Most of the wood and bamboo used outdoors have not been protected, and most of the protective agents used in the few treated wood and bamboo are not friendly to the environment. In recent years, chemical protective agents have been in...
