Biological enzyme wood and bamboo protective agent and its production and use method

Abstract

The invention relates to a bio-enzyme wood and bamboo protective agent which is prepared from the following raw materials in parts by weight: 0.05-0.5 part of laccase with the activity of 0.5U / mg, 0.05-0.5 part of enzyme activator, 200-2000 parts of bactericide substrate and 8000-9800 parts of buffer solution with the concentration of 0.1mol / L and pH value of 4-6. A production method of the protective agent comprises the steps of mixing the rest three raw materials according to the proportion except the laccase, evenly stirring at the temperature of 25-30 DEG C, and feeding the laccase into the mixed solution before use; evenly stirring at the rotating speed of 200-1000r / min under the condition of 25-30 DEG C. When the bio-enzyme wood and bamboo protective agent is used, the wood, the bamboo and products of the wood and the bamboo can be treated in a way of spraying, coating, soaking, pressurizing or vacuum impregnation, and then reaction is carried out for 6-18 hours in the environment of 25-40 DEG C, so that the mould-proof and corrosion-resistant treatment for the wood and the bamboo can be completed. The bio-enzyme wood and bamboo protective agent is simple in production technology, low in cost, convenient to use, non-toxic, free from environment pollution, good in mould-proof and corrosion-resistant effects, high in flow-away resistance and degradability resistance, and lasting in effect.

Description

technical field [0001] The invention relates to a biological enzyme wood and bamboo protective agent for protecting wood and bamboo from mildew and corrosion by means of dipping and the like, and a production and use method thereof. Background technique [0002] As a biopolymer material, wood and bamboo are vulnerable to mold, decay, insects and discoloration caused by biological factors such as fungi and insects. Especially bamboo, due to the high content of sugar and starch in the bamboo tissue, it often reduces or even loses its original value due to mildew during processing, transportation and use, causing serious economic losses to the bamboo product industry. At present, physical treatments such as baking, steaming, microwave, soaking in water, fumigation, etc. or chemical agents such as pentachlorophenol and its sodium salt are mainly used to solve the problem of wood and bamboo mildew. Although chemical antifungal agents are effective, they are toxic to humans and t...

AI Technical Summary

Problems solved by technology

Although chemical antifungal agents are effective, they are toxic to humans and the environment, and most countries have restricted or banned their use

Other fungicides such as boric acid and borax have low toxicity, but because of their poor loss resistance, the active ingredients are easy to lose, the efficacy period is short, and they will cause environmental pollution

Copper-containing protective agents and organic fungicide-type protective agents have gradually gained attention, and then found that copper-containing protective agents such as ammonia-soluble copper quaternary ammonium (ACQ), copper azole (CuAz) and copper dimethyl dithiocarbamate (CDDC) still exist Many problems, such as the potential harm of the metal component copper to the soil and aquatic environment; the inefficiency or ineffectiveness of the corrosion inhibition of metal firmware and the infringement of other bacteria such as mold; and the organic fungicide-type protective agent also has insufficient loss resistance and is easy to Water, photodegradation and other problems
