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 an antiseptic treatment method for timber or bamboo. The method comprises the following steps of: (1) preparing a natural antiseptic agent; and (2) performing an antiseptic treatment process: diluting the natural antiseptic agent with benzene / alcohol solvent by 50 to 70 times; and treating the timber or bamboo for 8 to 10 hours at a bath ratio of 1 to 1.05-2.0 at room temperature under maintained pressure of between 2.0 and 3.0MPa, wherein the bath ratio is the volume ratio of the timber or bamboo to the natural antiseptic agent. The method has the advantages of simple operation process, high controllability, low cost, no complex chemical treatment, no need of expensive equipment, easy industrialization and broad application prospect.

Description

technical field [0001] The invention relates to a wood or bamboo treatment method, in particular to a wood or bamboo antiseptic treatment method. 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 bamboo due to rot and insects accounts for about 10% of the world's 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 increasingly neglected due to their known or potential side effects, while natural ...
