Problems solved by technology

Ethylene (propane) acylation of wood has a good treatment effect, but ethylene (propane) acylation of wood requires high temperature, confined space, the acid anhydrides and catalysts used are relatively toxic, and the industrialization reaction is not complete, and unreacted acid anhydrides and catalysts are recovered Difficult to cause pollution; the preservatives used for preservative soaking usually contain high toxicity, affecting reprocessing or causing harm to the human body; the coating of creosote oil has a general protective effect, and the solvent is highly volatile, which affects the surface coating to a certain extent layer attachment

Abstract

The invention relates to a wood protective agent. Raw materials of the wood protective agent comprise, by weight, 50-60 parts of perfluor group modified polyvinyl alcohol, 15-20 parts of nanosilicon dioxide, 1-1.5 parts of a hyamine positive ion fluorocarbon surfactant, 5-10 parts of ethyl alcohol, 1-1.5 parts of a bactericide and 110-120 parts of water. The structural formula of the perfluor group modified polyvinyl alcohol can be found in the specification, x=3-7, and y=3-7. The wood protective agent is used for conduting protection treatment on wood, and has excellent water resistance, alcohol resistance, transparency and pencil hardness performance.

Description

technical field [0001] The invention relates to the technical field of coatings, more specifically, it relates to a wood protective agent and a production method thereof. Background technique [0002] Wood is one of the main natural materials for industry, agriculture, national defense, and civil use today. It has many advantages such as easy processing, natural beautiful patterns, luster, and color, and is widely used in furniture and other occasions. However, due to water, bacteria, lignin, etc., natural wood will slowly rot and change color after processing, swell and shrink when wet, and then deform and crack. Rapid aging, yellowing, blackening. [0003] my country's timber resources are short, and the per capita forest area is less than 1 / 4 of the world's average level, ranking 134th in the world. With the implementation of natural forest protection projects and the continuous increase of timber consumption, the contradiction between supply and demand has become incre...
