Description
Technical field
The present invention relates to the wood preservation technology, relate in particular to a kind of wood preservation from decay mould inhibitor and preparation method thereof.
Background technology
The product that relates to wood preservation from decay, mildew-resistant on the existing market has independent insect-proof agent and mould inhibitor.The insect-proof agent aspect: if a few days ago on the insect-proof agent that uses on the market with organophosphorus compound, as chlopyrifos and pyrethroid coumpound such as fenvalerate, Permethrin, cypermethrin, Biphenthrin etc. is active ingredient, these compound effects cause middle kissing bug excitement, paralysis and death in the nervous system of insect.But in the human settlement, use heavy dose ofly, can cause certain negative and influence the health of humans and animals.Chlopyrifos particularly, the infant who is in contact with it for a long time has the potential risk of reproductive system irreversible lesion, and therefore, the U.S. has promulgated a decree and has forbidden being used for human settlement's control of insect.The mildew-resistant aspect of stopping: what use on the market mainly is compounds such as CCA (chromated copper aresenate), penta sodium pentachlorophenate, ACQ a few days ago, these compounds are owing to the arsenide or the penta sodium pentachlorophenate that contain people's tool carcinogenesis, thereby after handling timber with it, also can cause potential risk to the health of the humans and animals that is in contact with it.Therefore, utilize the product of more environmental protection to substitute them, the health of protecting the human and animal is had crucial meaning undoubtedly.
(publication number is: CN1947519) disclose the termite-proof anticorrisive agent of a kind of timber in the Chinese invention patent application, it is a primary raw material with boric acid, copper sulphate and potassium bichromate, suitably adding chaotropic agent is auxiliary material, by grind, sieve, stir, dissolve, the termite-proof anticorrisive agents of the formulated water base property of production technology such as precipitation, filtration.But this product high effect nontoxic, pest control and anticorrosion mildew-resistant easy to use, pollution-free.
(publication number is: CN1651203) disclose a kind of water soluble timber protective agent, it is formulated by following weight percentages: chromium trioxide 33～65%, cupric oxide 16～22%, diarsenic pentoxide 14.7～48%, copper silicon emulsion 1.5～3.0% in the Chinese invention patent application.The said preparation safety non-toxic has good water-solubility, the timber after said preparation is handled, and bonding strength and paint film adhesion are unaffected, and insect protected, mildew-resistant, anticorrosion and good water-proof effect, and environmentally safe is applicable to the various environment of indoor and outdoor.
(publication number is: CN1436465) disclose a kind of bamboo and wood protecting agent, it is based on zinc salt, boric acid, borate, adds in fluoride, quaternary ammonium salt, Bravo, five ammonia phenol sodium, the Phoxim emulsion one or both in the Chinese invention patent application.This invention has efficiently, insect protected, mildew-resistant and effect such as anticorrosion.
Summary of the invention
In order to solve the technological deficiency that there is not environmental protection in above-mentioned wood preservation from decay mould inhibitor, the object of the invention provides a kind of wood preservation from decay mould inhibitor, and it has efficiently, wide spectrum, environmental protection, good aqueous solubility and fixed characteristics.In addition, another object of the present invention provides the preparation method of above-mentioned wood preservation from decay mould inhibitor.
In order to realize first purpose, the present invention has adopted following technical scheme:
A kind of wood preservation from decay mould inhibitor comprises insect-proof agent, mould inhibitor, solvent, cosolvent, penetration-assisting agent and stabilizing agent, and wherein the weight percent content of each component is respectively:
Insect-proof agent 0.1～70% mould inhibitor 0.1～50%
Solvent 1～40% cosolvent 1～30%
Penetration-assisting agent 1～20% stabilizing agent 1～40%.
As preferably, the weight percent content of above-mentioned each component is respectively:
Insect-proof agent 2～35% mould inhibitors 5～40%
Solvent 10～35% cosolvents 5～20%
Penetration-assisting agent 10～20% stabilizing agents 5～20%.
As preferably, the insect-proof agent in the above-mentioned prescription is one or more in boric acid or the borate.As preferred again, the insect-proof agent in the above-mentioned prescription is Firebrake ZB or Boratex or both mixtures.
As preferably, the mould inhibitor in the above-mentioned prescription is the mixture of one or both or three kinds in mildew-resistant azoles, copper 8-quinolinolate and the copper naphthenate.
As preferably, the solvent in the above-mentioned prescription is one or both the mixture in glycerine and the water.
As preferably, the cosolvent in the above-mentioned prescription is one or both the mixture in dicyandiamide and the polyethylene glycol.
As preferably, the penetration-assisting agent in the above-mentioned prescription is one or both the mixture in polyvinyl alcohol and the ring ethanol.
As preferably, the stabilizing agent in the above-mentioned prescription is one or more the mixture in ethyl acetate, propyl acetate, sodium acetate, the sodium dihydrogen phosphate.
In order to realize second purpose, the present invention has adopted following technical scheme:
The preparation method of above-mentioned wood preservation from decay mould inhibitor comprises the steps: the described insect-proof agent of prescription and partial solvent, cosolvent heating for dissolving; To fill a prescription described mould inhibitor and partial solvent, cosolvent heating for dissolving; The insect-proof agent and the mould inhibitor of above-mentioned dissolving are mixed, in mixed liquor, add penetration-assisting agent and stabilizing agent; Stir, promptly get described wood preservation from decay mould inhibitor.
The present invention has adopted above-mentioned technical scheme, and the form of solution is made in the Vermins-proof mildew-proof agent, makes protective treatment simple and easy to do.But because insect-proof agent and the solubility of mould inhibitor composition in solvent are lower, therefore, the present invention need add 1～30% cosolvent when adding solvent, promote insect-proof agent and the solubility of mould inhibitor in water.After adding solvent and cosolvent,,, cause the insect protected of product, anti-mold effect to descend owing to active component in the storage process is easily separated out from solvent, crystallization though can promote its solubility in water.Therefore, the present invention need add stabilizing agent, can promote the stable of the aqueous solution, even active component is not also separated out at a lower temperature, thereby has greatly improved product quality.
In addition, owing to the infiltration of Vermins-proof mildew-proof agent solution at wood surface divides from longtitudinal dispersion and horizontal infiltration dual mode.The adding of penetration-assisting agent can improve intercellular diffusion of water-soluble active ingredient and infiltration greatly among the present invention, promotes that active component penetrates in the wood cell from wood surface.On the one hand, increase the Vermins-proof mildew-proof effect of product, in addition on the one hand, can prevent to run off, make the protection of handling material permanently effective.
