Abstract
The present invention discloses a wood preservative and a production method thereof, and belongs to the field of wood preservative. The wood preservative is prepared from the following raw materials by weight: 15-25% of zinc pyrithione, 1-3% of butyl triazole, 1-3% of bitertanol, 5-15% of boric acid, 2-4% of didecyl dimethyl ammonium chloride, 2-4% of didecyl dimethyl ammonium carbonate, 20-30% of propanol, 10-25% of ammonia water, and the balance of water. The wood preservative of the present invention has advantages of good stability, strong loss resistance, low consumption, and low cost.
Description
Technical field
The present invention relates to wood preservation field, especially relate to a kind of timber preservative containing triazole and manufacture method thereof.
Background technology
Timber is bioabsorbable polymer material, there is obvious biological characteristics, thus variable color, rotten and damage by worms very easily is caused by the harm of bacterium, insect and microorganism, have a strong impact on the use of timber, particularly outdoor serviceability, reduce the life-span, increase consumption, not only waste resource, also limit the application of timber, thus bring huge economic loss.Be directed to the preservation of timber against decay, except will strengthening the administration of health from raw material to product processing, anticorrisive agent with strong points also should be used to control domestomycetes, insect and the microorganism pollution and harm to timber.
The anticorrisive agent mainly copper chromium arsenic (CCA) of domestic current use, a small amount of gardens material uses ammoniacal copper quaternary ((ACQ).CCA once at home and abroad widely used, and after the timber of CCA process exceedes its service life, waste wood process is more difficult, burn as adopted and the recovery of heavy metal, the absorption recovery etc. of heavy metal after microbial decomposition.In CCA, chromium, arsenic are heavy metal, have greater environmental impacts, and it strictly limits use in some countries, and as forbidden using in the place contacted with people, its consumption declines year by year.
Compared with traditional timber anticorrisive agent CCA (chromated copper arenate), the more environmental protection of copper azole anticorrisive agent, compared with ACQ anticorrisive agent, copper azoles process dosage is lower, and cost is comparatively cheap, is applicable to applying.ReimerGoettsche described in United States Patent (USP) 6441016B2 in 2002 copper, Cyproconazole, amido alcohol, surfactant/phosphorus-containing compound preparation for wood preservation, wherein copper 2.5-45%, Cyproconazole 0.5-15%, amido alcohol 5-50%, surfactant 0.5-30%.But in this copper triazole preparation, the solubility of triazole in water is minimum, easily precipitates, after process timber, the fixed amount of its active ingredient is less, affects its anticorrosion insecticidal effect.
Summary of the invention
Goal of the invention of the present invention is: for above-mentioned Problems existing, provides a kind of timber preservative of anticorrosion good disinsection effect.Anticorrisive agent of the present invention has good stability, and resistance leachability is strong, the advantage that use amount is little and cost is low.
The technical solution used in the present invention is as follows:
A kind of timber preservative, be made up of the raw material of following weight portion:
The present invention also provides the preparation method of above-mentioned timber preservative, it is characterized in that comprising the following steps:
(1) raw material is got out according to weight proportion;
(2) prepare triazole solution: by the triazbutil of aequum, Bitertanol is dissolved in propyl alcohol, then add didecyldimethylammonium chloride and didecyl dimethyl ammonium carbonate, triazole compounds is dissolved completely, makes triazole solution;
(3) prepare complex compound: in reactor, first add water, add zinc pyrithione fast, stir, slowly add ammoniacal liquor again, limit edged stirs, and controls to add speed and prevents the ejection of reaction vigorous reaction liquid, after zinc salt dissolves completely, then add boric acid, be then cooled to 50 DEG C;
(4) add triazole solution in the most backward complex compound, stir, namely make timber preservative.
Add in preparation and give bell and to slit cation husband and active chaste tree. can improve the stability of chaste tree processed, three can not precipitate.
Compared with prior art, the present invention has the following advantages:
(1) add didecyldimethylammonium chloride and didecyl dimethyl ammonium carbonate in preparation and be used as surfactant, add season in preparation by cationic surfactants, can improve the stability of preparation, triazole can not precipitate.In addition, ingot cationic surfactants itself also has certain antibacterial activity season.
(2) the present invention is while guaranteeing antiseptic insect-repelling performance, considerably reduces the ratio of triazole and copper and the use amount of triazole class compounds, reduces manufacturing cost.
(3) use ammoniacal liquor to make part in the present invention, the fixation rate of copper higher than or the fixation rate that is equivalent to when making part with aminoethanol, fixation rate is in higher scope.
In addition, preparation technology of the present invention, the order added and time, is made full use of the heat that anti-raw material should produce, is not needed other heating in whole production engineering by control reaction raw materials.
Detailed description of the invention
Below by way of specific embodiment, the invention will be further described.
Embodiment 1
A kind of timber preservative, be made up of the raw material of following weight portion:
Embodiment 2

Embodiment 3
The timber preservative of embodiment 1 and 2 is prepared by following steps, comprises the following steps:
(1) raw material is got out according to weight proportion;
(2) prepare triazole solution: by the triazbutil of aequum, Bitertanol is dissolved in propyl alcohol, then add didecyldimethylammonium chloride and didecyl dimethyl ammonium carbonate, triazole compounds is dissolved completely, makes triazole solution;
(3) prepare complex compound: in reactor, first add water, add zinc pyrithione fast, stir, slowly add ammoniacal liquor again, limit edged stirs, and controls to add speed and prevents the ejection of reaction vigorous reaction liquid, after zinc salt dissolves completely, then add boric acid, be then cooled to 50 DEG C;
(4) add triazole solution in the most backward complex compound, stir, namely make timber preservative.
The present invention is not limited to aforesaid detailed description of the invention.The present invention expands to any new feature of disclosing in this manual or any combination newly, and the step of the arbitrary new method disclosed or process or any combination newly.
