Abstract
The invention, belonging to the field of wood preservative, relates to a new organic-solvent preservative, its preparation and application. The new preservative comprises the following ingredients: 9.0-11.0 wt% of copper oxine, 4.0-6.0 wt% of permethrin, 9.0-11.0 wt% of nickel 2-ethylhexanoate and 72-78 wt% of inert solvent oil. The preservative is prepared by adding a certain amount of permethrin which is a durable permethrin pesticide with certain insecticidal effects and good environmental performance. The ingredients of the preservative take effect synergistically, all have good effects of resisting mildew, corrosion, insect and termite, have low animal toxicity, low ecotoxicity and other combination properties, and have good intersolubility, excellent property of complexation and stability. The preservative can be widely used for packaging and transportation or for the antisepsis of packing timber for holding unprocessed agricultural products.
Description
Technical field
The invention belongs to wood preservative field, relate to a kind of novel organic-solvent preservative and preparation and application.
Background technology
In traditional preservative, CCA preservative has poisonous chromium arsenic compound, although ACQ and the environmental protection of CA preservative, wherein organic volatile object height.And copper 8-quinolinolate is a kind of environment-friendly type organic-solvent preservative using in the world the eighties, nineteen ninety-five is listed U.S. AWPA standard in, common and mineral oil vehicle is configured to oil-soluble treatment fluid, but also there are some manufacturers that it is become to water miscible formula abroad, it is the wood preservative that unique U.S. food medicine office accepts, can be used in packaging, transport or for holding crude agricultural product as grain depot, stock barn, and food packaging material is anticorrosion, to Playground equipment, Picnic table, bridge plank and truck lathe, in refrigerator storage configuration, wood preservative is also ideal preservative.After treating of wood, there is antibacterial waterproof feature.But copper 8-quinolinolate is not bery effective to insect protected and control termites, and kiss the earth easily decomposes loss, limited its range of application.
Summary of the invention
The object of this invention is to provide a kind of organic-solvent preservative and preparation and application of new improvement, to overcome deficiency of the prior art.The present invention passes through years of researches, obtain a kind of novel preservative (Cu-8P preservative), described preservative is by adding a certain amount of permethrin to obtain, and its fungicidal properties, antiseptic property, control termites performance, animal toxicity are little etc. has obtained further raising and strengthening.
Described preservative of the present invention is referred to as Cu-8P preservative.
In order to solve above-mentioned prior art, the present invention adopts following technical scheme to realize:
Cu-8P preservative of the present invention, comprises the component of following weight percentage:
Preferably, described Cu-8P preservative, comprises the component of following weight percentage:
Described 2 ethyl hexanoic acid nickel is cosolvent.

Described permethrin (C
21h
20clO
3) be that m-phenoxy benzyl (±) is suitable, trans-2,2-dimethyl-3-(2,2-dichloroethylene) cyclopropanecarboxylcompound, its structural formula is suc as formula shown in (I):
In the middle of described permethrin, phenoxy benzyl (±) is suitable, trans-2, and in 2-dimethyl-3-(2,2-dichloroethylene) cyclopropanecarboxylcompound, cis and trans content do not limit, and both proportionings are any.
Described permethrin is a kind of insecticide of broad-spectrum insecticidal activity, has and tags and stomach poison function, without stifling and systemic action.Low little with excitant to higher mammal toxicity, can be used for preventing and treating the insect on sanitary insect pest and multiple leaf class crop.Kard etc. (1998) report, year is processed soil with 1% permethrin, and holding effect reaches 5～15 years.Rat, rabbit are acute through skin LD50 > 2000mg/kg, and it is > 23.5g/m that rat acute sucks LC50
3, rabbit is had no stimulation through skin, eyes are had to slight spread effect, the property accumulated is little in vivo, under experimental condition without teratogenesis, without mutagenesis, without carcinogenesis.
The preparation method of Cu-8P preservative of the present invention, comprises the steps:
(1) first atent solvent oil is dropped in preparing tank according to proportioning.
(2) open high shear homogeneous emulsifying machine on one side, according to proportioning, copper 8-quinolinolate and 2 ethyl hexanoic acid nickel are added in atent solvent oil on one side, obtain mixed liquor.
(3) in the mixed liquor of step (2) gained, drop into permethrin according to proportioning, after stirring reaction, obtain described Cu-8P preservative.
Preferably, in step (2), described in all adopt the form slowly adding while adding copper 8-quinolinolate and 2 ethyl hexanoic acid nickel.The speed of described emulsifying adopts conventional speed, or required speed, or according to the emulsifying speed of traditional Cu-8 preservative.
Preferably, in step (3), the described reaction time is 2.5～3.5 hours.
The beneficial effect that Cu-8P preservative of the present invention has:
Cu-8P preservative of the present invention be in Cu-8 preservative by add a certain amount of permethrin insecticide (P insecticide) obtain, low toxicity " P " insecticide adding, itself has certain insecticidal effect, and has good environmental-protecting performance; The each component of Cu-8P preservative of the present invention is worked in coordination with onset, and there is good mildew-resistant simultaneously, the combination property such as anticorrosion, insect protected is termite-proof and animal toxicity eco-toxicity is low, and the intersolubility of each component is good, there is excellent coordination and stability, its each complete function is improved, through properties test, confirm that novel Cu-8P preservative effectiveness is more obvious.
Cu-8P preservative of the present invention can be widely used in packaging timber, transport with timber, material (holding crude agricultural product) for grain depot, timber, food packaging timber etc. for stock barn.
