Abstract

The invention discloses a nano preservative wood protective agent and a preparation method thereof. The nano preservative wood protective agent is prepared from the following raw materials: nano zinc oxide, nano tin dioxide, isobutylene triethoxy silane, dodecyl dimethyl benzyl ammonium chloride, a preservative, carboxymethyl cellulose sodium, n-butyl alcohol, polyethylene glycol, polyvinyl alcohol, boric acid and sorbitol. According to the nano preservative wood protective agent disclosed by the invention, nano-scale zinc oxide and tin dioxide are adopted, so that the corrosion resistance and the oxidation resistance are improved. The prepared preservative wood protective agent has extremely high preservative capacity, has an obvious effect of inhibiting decay of fungi, and can avoid various insect pests of wood at the same time; thereby, the quality of the wood is not reduced in the process of cutting and transporting standing wood to manufacturing the wood into products, the original color and quality are kept, and the application range is wide.

Description

technical field [0001] The invention belongs to the technical field of wood protective agents, and in particular relates to a nano antiseptic wood protective agent and a preparation method thereof. Background technique [0002] As an indispensable material in life, wood has hidden dangers of double damage in the process of felling, storage, circulation and final use. If it is not preserved properly, the wood is prone to cracking, denaturation, decay by fungi, insects, etc., which will reduce or even lose its original value. [0003] There are many factors that cause wood decay and deterioration, mainly including biological decay, physical decay and chemical decay, among which the most important is biological decay, that is, fungal discoloration, decay and insect damage. They not only damage standing logs, logs during storage and transportation and sawn timber, but also spoils air-dried wood products. [0004] Therefore, in order to maintain the original quality of wood and...
