Outdoor bamboo wood natural mould-proof corrosion-proof agent and preparation and treatment methods thereof

Abstract

The invention relates to the technical field of bamboo wood mould proofing and corrosion proofing, in particular to an outdoor bamboo wood natural mould-proof corrosion-proof agent and preparation andtreatment methods thereof. The bamboo wood natural mould-proof corrosion-proof agent is prepared from the following components in percentage by weight: 30-40% of industrial wastewater after stevia rebaudiana is processed to prepare stevioside, 5-10% of soapberry fruit, 20-30% of melia azedarach leaf, 10-15% of folium coptis chinensis and 10-20% of folium isatidis. According to the preparation method of the bamboo wood natural mould-proof corrosion-proof agent, conventional decoction or alcohol extraction is adopted; the method for treating bamboo wood by means of the bamboo wood natural mould-proof corrosion-proof agent comprises the steps that after the bamboo wood is placed in hot water for soaking treatment or placed in an ethyl alcohol solution for soaking treatment, the bamboo wood natural mould-proof corrosion-proof agent is used for treatment. The outdoor bamboo wood natural mould-proof corrosion-proof agent and the preparation and treatment methods thereof have the beneficialeffects that firstly, the bamboo wood is placed in the alcohol solution for soaking to make large amounts of starch, sugar, protein and other salt substances in bamboo wood tissues are extracted through alcohol; therefore, the condition that the natural organic mould-proof corrosion-proof agent penetrates through parenchyma cells and vascular bundles of the internal tissues of the bamboo wood is more easy; the mould-proof corrosion-proof agent is prepared from the natural organic extracts and do not have any toxicity or cause pollution problems to the environment.

Description

Technical field [0001] The invention relates to the technical field of bamboo anti-mildew and anti-corrosion, in particular to a natural anti-mildew and antiseptic agent for outdoor bamboo and a preparation and treatment method thereof. Background technique [0002] Bamboo contains more nutrients than wood. Bamboo tissue contains a large amount of starch, sugar, protein and other salts. It has poor natural durability and is prone to decay, mildew and moth. Its hardness, strength and usability are great. Reduce or even lose. In order to improve its effective utilization, extend its service life, and tap its resource potential to the greatest extent, the work of anti-corrosion, insect prevention and mildew prevention of bamboo is particularly important. [0003] The protection methods of bamboo and bamboo products are mainly divided into two categories: one is physical methods, such as infrared heating method, steaming method, baking method, microwave method, ultrasonic method, etc....

AI Technical Summary

Problems solved by technology

The main advantages of the physical method are low toxicity and less environmental pollution, but the effect of killing insects is poor; the chemical method has a good protective effect, a long validity period, and does not damage the physical and chemical characteristics of bamboo, but the disadvantage is that chemical agents are prone to toxicity and environmental pollution.

[0004] Therefore, the selection of high-efficiency, low-toxic, environmentally friendly natural organic preservatives for bamboo and i
