Abstract

The invention discloses a nontoxic environmentally-friendly wood preservative. The nontoxic environmentally-friendly wood preservative is characterized by being prepared through the following raw materials in parts by weight: 15 parts of sodium dodecyl sulfate, 7 parts of trimethyl borate, 6 parts of polyethylene acid ester, 7 parts of butyl carbamate, 4 parts of twain-20, 4 parts of OP-10, 4 parts of lauryl diethanol amine, 5 parts of polyethylene glycol, 6 parts of glycerin, 2 parts of p-hydroxybenzoic acid monosodium salt, 2 parts of potassium sorbate, 8 parts of diatom ooze, and 150 parts of deionized water. The wood preservative has the following advantages: (1) the environment is protected, and no pollution is caused; the production and use do not damage the environment and human body; (2) the self stability is high, and decomposing or falling off in general environment can be avoided; (3) the antibiotic spectrum is wide; general bacteria which can corrode wood can be eliminated and inhibited; and (4) the applicable scope is wide; the nontoxic environmentally-friendly wood preservative is applicable to corrosion prevention of wood used in buildings, furniture, ships and other environments.

Description

Technical field [0001] The invention belongs to the technical field of antiseptic materials, and specifically relates to a non-toxic environmentally friendly wood preservative and a preparation method thereof. Background technique [0002] Wood is a natural and renewable biological material. Its development and utilization meet the requirements of environmental protection. However, one of its main disadvantages is that it is vulnerable to damage from fungi, insects and marine borehole animals, which affects its use. Preservative treatment of wood with chemical agents can extend its service life. Preservatives play a key role in wood preservative treatment and are the key to wood preservative technology research. [0003] The traditional wood preservative industry mainly relies on the first-generation wood preservatives that have the advantages of broad-spectrum antibacterial, low cost, and long-lasting efficacy, including creosote, oil-borne pentachlorophenol and water-borne chrom...
