Problems solved by technology

At present, there is no relevant policy in our country, and the anticorrosion and antifungal agents used are mainly of this series, and the dosage is relatively large. It is imperative to find a new environment-friendly anticorrosion and antifungal agent to reduce the amount of chromium, arsenic and copper series.

Abstract

The invention provides an anti-septic and anti-mildew agent for bamboo and wood, which is obtained by adding zinc compounds, copper compounds and cationic surfactant to substrates. The invention adopts bamboo vinegar, wood vinegar and grass vinegar as main ingredients and is composed by water-insoluble inorganic compounds to prepare biological (of a chemical type) wood preservative and can also be added with ammonia, ammonium salt or nitrogen compounds of the ammonia to increase the solubility. The invention has the advantages of strong resistance of leachability (wastage rate is less than 2 percent), low moisture absorption, no frosting, low toxicity and good effect of anti-sepsis and anti-mildew, and can also be applied to discoloration of timber or bamboo.

Description

(1) Technical field [0001] The invention relates to an antiseptic and antifungal agent for bamboo wood materials. (2) Background technology [0002] Bamboo and wood materials contain the nutrients needed by microorganisms. In what environment, microorganisms are easy to damage and degrade bamboo and wood materials. The light reduction of the grade will have little effect on the bamboo and wood materials themselves, and the serious ones will make them lose their use value and cause resource pollution. Waste, so general bamboo and wood materials need to be treated with anti-corrosion and anti-mildew before use. [0003] At present, bamboo wood preservatives at home and abroad mainly include oil preservatives, oil-borne preservatives and water-borne preservatives, and water-borne preservatives are the most widely used. In addition to the toxicity of oil preservatives to humans and animals and the impact on the environment, another major disadvantage is that the surface of the ...
