Abstract
The invention discloses a mixture containing nanometer level copper compound and preparation method of the same. Component and weight percentage content of the mixture is: copper compound of 1.0-2.0 %, surface active agent of 1-5 %, solvent of surplus, wherein the copper compound particle is 50-100 nm. The production of the invention can act as protection agent of wood and has greatly protection effect.
Description
Technical field
The present invention relates to a kind of protective agent, especially relate to a kind of mixture that contains nano copper compound and preparation method thereof.
Background technology
The compound of copper is one of the most common very important again component in the timber protective agent, but in order to make the compound dissolving of copper, all to consume a large amount of solvents, for example come dissolved oxygen copper with chromic acid and arsenic acid among the CCA, in ACQ, dissolve basic copper carbonate with ammoniacal liquor or monoethanolamine, these solvents are mostly poisonous in fact, during volatilization environment is produced pollution, these insoluble copper compounds are fine to be dispersed in the timber preservative then both to have saved solvent if still can make without these solvents, reduced cost, improved environment again, according to the principles of chemistry under certain condition these insoluble copper compounds, make it become the nanometer copper compound, be dispersed in the protective agent, because after the nanometer, the particle size of copper compound, has only tens～hundreds of nanometers size, in vacuum pressed, spray, brushing, in the technical process such as immersion, can enter into timber inside in various degree.
Summary of the invention
Purpose of the present invention mainly is for solving the prior art protective agent, existing copper compound protective agent needs amine or Ammonia solvent, easily environment is caused dysgenic shortcoming, a kind of mixture that contains nano copper compound and production method thereof that ammonia or amine solvent can use that need not is provided.
For realizing above purpose, the present invention is achieved through the following technical solutions:
A kind of mixture that contains nano copper compound is characterized in that, each component title and weight percentage are:
Copper compound 1.0-2.0%; Surfactant 1-5%; Solvent: surplus;
Wherein, described copper compound particle diameter is 50-100nm.
Wherein, described copper compound is selected from basic copper carbonate, Kocide SD.
Described surfactant is selected from PVP, K-12, OP-10, PVA.
Described solvent is selected from water, quaternary ammonium salt.
The described pair alkyl-dimethyl ammonium chlorides that are selected from, two alkyl carbon chain length of wherein said pair of alkyl-dimethyl ammonium chloride are C
8-C
14
The described mixture pH value that contains nano copper compound is 8-10.
Preparation contains the method for the mixture of nano copper compound, it is characterized in that, comprises step: A: add surfactant in the soluble copper compound; B: add precipitating reagent in the solution that in the A step, obtains, stirred 1-2 hour, keep 25-35 ℃ of temperature, pH value 8-10 in the whipping process.
Described soluble copper compound is selected from copper sulphate, copper chloride, Schweinfurt green.
Described surfactant is selected from PVP, K-12, OP-10, PVA.
Wherein, described PVP is a PVP, k～12nd, and lauryl sodium sulfate, OP-10 is an APES; PVA is a polyvinyl alcohol, all can buy from market to obtain.
Described precipitating reagent is selected from sodium carbonate, NaOH, sodium acid carbonate or carbonic hydroammonium.
Wherein, described pair of alkyl-dimethyl ammonium chloride is specially: two octyldimethyl ammonium chlorides; Two hot decyl alkyl dimethyl ammonium chlorides; Two certain herbaceous plants with big flowers base alkyl dimethyl ammonium chlorides; Two dodecyl dimethyl ammonium chlorides; Varisoft 432PPG; Dioctadecyl dimethyl ammonium chloride; Most preferably be two certain herbaceous plants with big flowers base alkyl dimethyl ammonium chlorides.
Adopt LS Particle Size Analyzer to analyze the copper compound particle diameter that adopts set of dispense of the present invention preparation method's preparation when, particle size range is 50-100nm.
Timber protective agent among the present invention has following beneficial effect after testing:
1, the nanometer copper compound because can a water as solvent, just can reduce the cost of raw material of protective agent greatly, as being example,, can reduce the cost of raw material about 35% after the copper nanometer through slightly calculating just with copper amine (ammonia) quaternary amine (ACQ) timber protective agent.
2, the copper compound nanometer can directly act on the microorganism wall of timber and other materials afterwards owing to surface charge effect, stops the breeding of domestomycetes and other bacteriums, and its antibacterial ability greatly improves.
3, the nanometer copper compound be owing to can only make water as solvent, thus do not exist owing to amine or Ammonia solvent evaporates are attached anticorrisive agent out and run off, thus the fixed performance of anticorrisive agent greatly improves.
4, the nanometer copper compound can a water as solvent, so can be owing to the volatilization and the loss of amine or Ammonia solvent, and contaminated environment.
