Abstract
The invention belongs to a kind of preparation method of amonia-copper composite bacteriacide.The present invention is a raw material with the etching waste liquor in the board production process, and making in the etching waste liquor total copper content through allotment, neutralization is 2-10%, pH=7-10; Adding in the neutralizer of gained with neutralizer weight is that the percentage by weight of benchmark is that 0.5-5% organic phosphonate is as auxiliary agent, adding percentage by weight and be 0.5-5% HLB value and be 8-13 non-ionic surface active agent is emulsifier, mix fast, promptly make amonia-copper composite bacteriacide.The present invention not only provides a kind of new compound disinfectant for agricultural gardening department, but also provides a brand-new approach that utilizes for the etching waste liquor of circuit board factory.
Description
The present invention relates to the preparation method of agricultural chemicals, is a kind of preparation method of amonia-copper composite bacteriacide specifically.
The kind of the plain disinfectant use in agriculture of copper is a lot, had the developing history of decades with copper sulphate as bactericide, begin one's study from the seventies in the world and utilize the copper organic acid bactericide, occurred the amino acid copper fungicide in succession, complexing ammonia copper fungicide and copper oxychloride hydrate bactericide.They all have the sterilization wide spectrum, advantages such as the high and low poison of drug effect.But their production cost is too high, is difficult in China's extensive use.In addition,,, use inconvenience, also can not give full play to its drug effect because the copper oxychloride hydrate is water insoluble though the bactericidal effect of copper oxychloride hydrate is better than copper sulphate.
Contain that etching waste liquor often is difficult to handle in the board production process of copper element, processing method has two kinds, a kind of waste liquid is sent to special producer reclaim sulfuric acid copper; Another kind is then put to Da Chi and is added the alkali neutralization, precipitates a large amount of copper sludge slurries back discharge of wastewater.
The objective of the invention is to overcome the shortcoming of above-mentioned background technology, propose a kind of copper organic acid that contains simultaneously, copper sulphate, the preparation method of the amonia-copper composite bacteriacide of complexing ammonia copper and copper oxychloride.In utilizing the board production process, solved the problem of environmental pollution in this production process in the etching waste liquor.
Purpose of the present invention can reach by following measure:
The preparation method of amonia-copper composite bacteriacide is characterized in that, it is to be raw material with the alkaline etching waste liquid for producing in the board production, and through allotment, neutralization, emulsion process prepares amonia-copper composite bacteriacide;
(1) allotment
The waste alkali etching liquid of printed circuit boards thin up, extremely total copper content is 2-10%, optimum range is 4-5%;
(2) neutralization
In seasoning liquid, add diluted acid and be neutralized to neutralizer PH=7-10; Optimum range is PH=8-9;
(3) emulsification
With seasoning liquid weight is benchmark, the HLB value that adds its percentage by weight and be 0.5-5% is made emulsifier for the non-ionic surface active agent of 8-13, the organic phosphonate that adds percentage by weight simultaneously and be 0.5-5% is made auxiliary agent, mix fast and be amonia-copper composite bacteriacide, the optimum addition of emulsifier is 2-3% by weight percentage, and the optimum addition of auxiliary agent is 2-3% by weight percentage.
The present invention adopts in the board production process on the etched circuit board copper thin and ammonia copper complex that form is a raw material.The kind of circuit board etchant is a lot, and the speed that alkali formula etchant etching copper is thin can reach 50 μ m/min, contains copper organic acid, complexing ammonia copper, multiple copper compound such as copper oxychloride in the waste liquid after etched circuit board copper is thin.According to agricultural chemicals active drug dosage, the process chart that Fig. 1 designs for the present invention.
The present invention is described in further detail in conjunction with following embodiment.
Embodiment 1:
Get 10 milliliters of TS-28 type circuit board etching waste liquors, according to the EDTA titrate the analysis result, even the total copper content that adds in 40 milliliters the water seasoning liquid is 5.0%, PH=8.5 with the dilute sulfuric acid regulator solution, after stirring evenly, seasoning liquid adds 0204 agricultural emulsifier of 1.05 grams and the ethylene-diphosphonic acid of 0.5 gram immediately, mix fast, promptly obtain a kind of amonia-copper composite bacteriacide of avy blue.
1 milliliter of the amonia-copper composite bacteriacide that the absorption said method makes adds in 500 ml waters, stirs evenly, and is sky-blue homogeneous transparent liquid, leaves standstill more than 1 hour and produces sediment, is used to spray crops, and the obvious sterilization effect is arranged.
Embodiment 2
50 milliliters of sense circuit plate alkaline etching waste liquid for producing, analyze its total copper content with the EDTA titration, thin up to 200 milliliter, the analyzing total copper content is 4.2%, the pH value of regulating seasoning liquid with rare organic acid is 8.2, add fatty alcohol-polyoxyethylene ether surfactant 5.6 grams and ethylene-diphosphonic acid 2.5 grams, stir fast, promptly obtain amonia-copper composite bacteriacide.Draw 2 milliliters in above-mentioned preparation, add in 1000 ml waters, stir evenly, leave standstill and sediment did not take place in 2 hours, be homogeneous transparent sky-blue solution.
The present invention compares background technology and has following advantage:
1, because the etching waste liquor in this law employing board production process is raw material, in the production cost that reduces amonia-copper composite bacteriacide, administered etching waste liquor, overcome environmental pollution, and can turn waste into wealth. It not only provides a kind of new amonia-copper composite bacteriacide for agricultural gardening department, but also processes the brand-new approach that provides for the etching waste liquor of circuit board factory. So this law has good economic benefit and social benefit.
2, the HLB value of emulsion process adding is non-ionic surface active agent and the emulsifying agent organic phosphine hydrochlorate of 8-13, not only plant is had the growth regulating action, and in use dilute 500-800 times of water when above, do not produce sediment, dispenser is uniformly dispersed, and drug effect is good.
3, technology of the present invention is simple, and is easy to operate.
