Description

A kind of low toxicity timber preservative

Technical field

The present invention relates to a kind of low toxicity timber preservative.

Background technology

Timber is a kind of natural organic, has obvious biological nature, easily by biological attack such as bacterium, worm, the raw boring in sea worms.Before use, according to different applied environments, select suitable anticorrisive agent, carry out appropriate process, then effectively can delay foxiness.The timber that nowadays China use after preservative treatment is little, and mostly uses the mankind and the large traditional timber preservative of environmental hazard.Because traditional preservatives exists many deficiencies, force people to study and find person poultry harmless, environmentally safe, only poisonous to microorganism new food preservative.

Summary of the invention

For the deficiencies in the prior art, the problem to be solved in the present invention is, provide a kind of low toxicity timber preservative, toxicity is little, to person poultry harmless, has good anticorrosion moisture effect simultaneously.

For solving prior art problem, technical scheme provided by the invention is, a kind of low toxicity timber preservative, and it is made up of the raw material of following parts by weight:

Urea 3-8 part, tetrakis hydroxymetyl phosphonium sulfuric 7-10 part, borate 4-6 part, diatomite 6-10 part, acetic acid 4-9 part, lignin 4-6 part, hydrogen peroxide 4-7 part, caustic soda 5-10 part, anion surfactant 6-8 part, alcohol ether glucoside 3-6 part, semi-refined paraffin wax 6-11 part, sodium carboxymethylcellulose 6-8 part, poly methylene poly phenyl poly isocyanate 9-13 part.

The invention has the beneficial effects as follows: low toxicity timber preservative of the present invention, toxicity is little, to person poultry harmless, has good anticorrosion moisture effect simultaneously.
