Abstract
The invention discloses a novel timber protective agent comprising the following constituents (by weight percent): nanometer level CuO 7-11%, lemon acid 3-7%, and balancing water.
Description
Technical field
The present invention relates to a kind of protective agent, especially relate to a kind of timber protective agent.
Background technology
The general timber preservative in the world today mainly is copper, chromium, arsenic (CCA), copper amine (ammonia) quaternary ammonium salt (ACQ) and copper azoles (CA) etc. because the arsenic chromium among the CCA all is noxious material, easily cause damage to human body, during especially indoor use, bigger to the harm of human body.In the prior art, begun to substitute CCA by efficient low toxic and environment-friendly anticorrisive agent such as ACQ, CA, timber protective agent of the prior art all is that sterilization protection composition ammonification or amine solvent are formulated, sterilization component and solvent (amine, ammonia) are formulated, melt copper compound and reach the sterilization protection effect for reaching, ammonia or amine solvent are essential, so not only will consume a large amount of solvents, and because amine or Ammonia solvent volatilize easily environment are polluted.Volatilization owing to solvent tends to anticorrisive agent part component is taken out of fixed performance, the reduction sterilization virus killing effect that influences protective agent in addition.
China's wood preservation industry is in new developing period, CCA and ACQ timber preservative are all using simultaneously, antiseptic timber and woodwork greatly part all are used for the open air, because cuprammonium series anticorrisive agent all has color, and the volatilization of its solvent brings harmful effect to environment, so often limiting in the present anticorrosion wooden inlet chamber being extensive use of, therefore, pressing for that a kind of colourless nothing of development is smelt, environment-friendly type, multi-functionally be suitable for the timber protective agent that indoor and outdoor is widely used.
Summary of the invention
Purpose of the present invention mainly is that timber protective agent need use ammonia or amine as the deficiency that solvent brings in the prior art in order to solve, and a kind of Wood protective agent that need not amine, ammonia as solvent is provided.
For realizing above purpose, the present invention is achieved through the following technical solutions:
A kind of Wood protective agent is characterized in that, each component title and weight percentage are:
Nanoscale copper compound (content is in CuO) 7～11%
Citric acid 3～7%
Water surplus
Described nanoscale copper compound particle diameter is 50-100nm.
Preferably, each component title and weight percentage scope are
Nanoscale copper compound (content is in CuO) 8.8～9.3%
Citric acid 5.4～5.7%
Water surplus
Used nanoscale copper compound particle diameter is 50-100nm among the present invention.
Described nanoscale copper compound is selected from basic copper carbonate, Kocide SD.
Described citric acid is nontoxic citric acid.
Wherein, the nanometer basic copper carbonate can make by the following method, get 0.5mol/L hydrogen sulfate copper solution 50ml, add 1.0 gram PVP, PVP is a PVP, vigorous stirring 0.5 hour, add 1.0mol/L sodium acid carbonate 50ml, 1 gram OP-10, OP-10 is an APES, continue to stir 1-2 hour, can make particle diameter is the nanometer basic copper carbonate of 50-100nm.
In preparing the method for basic copper carbonate, change sodium acid carbonate into use NaOH, adjust the ratio of using, make reactant reaction complete, can make particle diameter is the nanometer Kocide SD of 50-100nm.
Beneficial effect of the present invention is:
1, after the copper compound nanometer, can a water as solvent, can reduce the cost of raw material of protective agent greatly, through just slightly calculating, can reduce the cost of raw material about 35% after the copper nanometer.
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.
