Environmentally friendly wood preservative

Abstract

The invention discloses an environmentally friendly wood preservative which comprises the following components in parts by weight: 10-15 parts of trimethyl borate, 25-30 parts of methylbenzene, 15-20 parts of 2-phenylimidazole, 40-65 parts of dodecyl dimethyl benzyl ammonium chloride, 3-10 parts of imidacloprid, 25-40 parts of methyl benzimidazol-2-ylcarbamate and 15-30 parts of an emulgator. According to the invention, all components have favorable synergistic effect, so that the environmentally friendly wood preservative has better corrosion resistance, and the leachability resistance of the environmentally friendly wood preservative is remarkably improved. In addition, toxic and harmful metals and compounds are not included in the formula, and harm of boron to the environment, human and livestock is less, so that the wood preservative is a novel environmentally friendly wood preservative with greater potential.

Description

technical field [0001] The invention relates to an environment-friendly wood preservative. Background technique [0002] Wood is a natural renewable biological material, its development and utilization meet the requirements of environmental protection, but one of its main disadvantages is that it is easily attacked by microorganisms, etc., thus affecting its use. The water-borne wood preservatives commonly used at present all contain metal elements, such as copper, chromium, arsenic, three inorganic oxides or inorganic salts, water-soluble wood preservatives (CCA), inorganic copper compounds and organic quaternary ammonium compounds Composed of wood preservatives (ACQ), etc., the biggest disadvantage of these wood preservatives containing metal elements is that they cause environmental pollution, especially CCA wood preservatives, because they contain chromium and arsenic, the pollution to the environment is relatively serious. Many countries have severely restrict...

[0002] Wood is a natural renewable biological material, its development and utilization meet the requirements of environmental protection, but one of its main disadvantages is that it is easily attacked by microorganisms, etc., which affects its use

The water-borne wood preservatives commonly used at present all contain metal elements, such as copper, chromium, arsenic, three inorganic oxides or inorganic salts, water-soluble wood preservatives (CCA), inorganic copper compounds and organic quaternary ammonium compounds Composed of wood preservatives (ACQ), etc., the biggest disadvantage of these wood preservatives containing metal elements is that they cause environmental pollution, especially CCA wood preservatives, because they contain chromium and arsenic, the pollution to the environment is relatively serious. Many countries have severely restricted their use

Even though it can effectively prevent microorganisms from invading wood, the impact of these preservatives on environmental safety and human health runs counter to the environmental protection characteristics of wood itself
