Description
Technical field
The present invention relates to a kind of timber additive and preparation method thereof.
Background technology
Along with the raising day by day and the science and technology development of people's living standard, people also improve constantly the performance requirement of timber (comprising solid wood, wood-based plate and other wood materials), especially the preservation of timber against decay, anti-flammability and insect protected performance.At present industrial copper chromium arsenic (CCA) anticorrisive agent or cuprammonium quaternary ammonium salt (ACQ) anticorrisive agent of adopting carries out the preservation of timber against decay processing more, yet the use of this class anticorrisive agent often produces harm to environment.Copper chromium arsenic or cuprammonium quaternary ammonium salt can enter surface water body at last if be lost in the soil, and its contained copper ion is biological harmful to the fish in the water body and other; And arsenical is more dangerous, because the people is the most responsive to arsenic, so arsenical is also maximum to people's harm, and especially containing the preserving timber of arsenic does not still have effective method of disposal after discarded.
Borate compounds (as boric acid and borax) has broad-spectrum sterilization and insecticidal action for wood-decaying fungus and insect, adopts boric acid, borax or the mixture of the two to carry out the preservation of timber against decay insect-prevention treatment as anticorrisive agent at present, has certain effect; Because borate compounds is nontoxic to people and animals, environmental sound is so be widely used at present again.
(solubility of 10 ℃ of boric acid in water is 2.17g but the present solubility of borate compounds Wood protecting agent in water is low; The solubility of borax in water is 1.6g), and dissolution velocity is slow, has influenced practical application effect; Especially prepare the higher fire retarding wood of medicine carrying amount (borate compounds), single-steeping is handled and is difficult to reach the carrying drug ratio requirement, needs repeatedly to handle could improve the medicine carrying amount, production cost height, complex process.In addition, the poor permeability of present borate compounds Wood protecting agent is so length consuming time is handled in impregnation of timber.
Summary of the invention
The objective of the invention is in order to solve the problem of present borate compounds and poor permeability low as the solubility of Wood protecting agent in water, and a kind of Wood protecting agent that provides and preparation method thereof.
Wood protecting agent of the present invention is made by 100 parts of borates and 0.1～5 part of complexed surfactant by ratio of weight and the number of copies; Borate is wherein made by boric acid and borax solid phase reaction, and the mol ratio of boric acid and borax is 3.8～4.2: 1; Complexed surfactant wherein is made up of 90%～99% hc-surfactant and 1%～10% fluorine surfactant by mass percentage.
Above-mentioned Wood protecting agent prepares according to the following steps: one, is that 3.8～4.2: 1 boric acid and borax mix, places environment solid phase reaction 0.5～180h of 25 ℃～75 ℃ again mol ratio, and dry then, obtain borate; Two, complexed surfactant and the borate of getting borate quality 0.1%～5% mixes, and promptly obtains Wood protecting agent; Complexed surfactant wherein is made up of 90%～99% hc-surfactant and 1%～10% fluorine surfactant by mass percentage.
Hc-surfactant is lauryl sodium sulfate, neopelex, APES sulfate, AEO or APES among the present invention.
Fluorine surfactant is perfluoro octyl sulfonic acid salt, fluorinated alkyl sulfonate, perfluoro capryl APEO, perfluoroalkyl polyoxy vinethene or perfluoro carboxylic acid macrogol ester among the present invention.
Wood protecting agent of the present invention is amorphous state, white powder particulate, and density is low, and bulk density is 0.5～0.8g/cm
3Wood protecting agent solubility height of the present invention; solubility under 10 ℃ of conditions in the water is 10g; solubility under 25 ℃ of conditions in the water is 20g; solubility under 50 ℃ of conditions in the water is 34g; and good dispersion, good fluidity; dissolution velocity fast (stirring is a solubilized) is easier to be scattered in sticky aqueous medium in not only soluble in water, is of value to Wood protecting agent immersing wood of the present invention.
Wood protecting agent of the present invention is to the person poultry harmless, produce and use in free from environmental pollution, can be used for solid wood, wood-based plate and other wood materials protective treatments, have anticorrosion, insect protected, termite-proof, fire-retardant and press down the function of cigarette; And do not influence outward appearance, mechanical property and the processing characteristics of processed wood materials.
Wood protecting agent Acidity of Aikalinity gentleness of the present invention (the pH value is 7.0～8.0) near neutral, does not produce acid catalysis or base catalysis degradation to timber, therefore the mechanical property long-term stability of the timber of handling through Wood protecting agent of the present invention.
The content of boron＞20% (quality) in the Wood protecting agent of the present invention; apparently higher than borax (content of boron is 11.3%) and boric acid (content of boron is 17%); therefore handle timber through Wood protecting agent of the present invention and not only have excellent anticorrosion, insect protected and termite-proof function, and fire-retardant and smoke suppressing significantly improves.
Vacuum pressure impregnating is handled because Wood protecting agent good dispersion of the present invention, good fluidity, permeability can adopt by force, normal pressure is handled and the deep diffusion method is handled timber (Wood protecting agent employing deep diffusion method of the present invention can be to high-moisture percentage timber, and the timber of moisture content＞50% is handled, protected).The wood surface cleaning that Wood protecting agent of the present invention was handled, have no irritating odor, operating personnel add and also need not man-hour to protect specially; Treated timber does not change wood color, and the oil free sense can be used for anticorrosion, the insect protected protection of indoor decoration timber and historic building structure.
The preparation method of Wood protecting agent of the present invention is simple, operation easily, and harmless to operating personnel.
