Abstract
The invention provides an efficient environment-friendly multifunctional cooling water biocide. The biocide comprises, in weight percentage, 50%-55% of dodecyl dimethyl benzyl ammonium chloride, 20%0-25% of decyl dimethyl benzyl ammonium, 5%-10% of tetradecyl dimethyl benzyl ammonium chloride, 5%-8% of polyquaternium, 5%-7% of polyoxyethylene lauryl ether, 2%-5% of decyl phenol polyoxyethylene ether and 1%-2% of defoaming agents which are mixed to form the biocide. The biocide is low in toxicity and environmental pollution, free from irritation, remarkable in effect, simple in preparation method and convenient to operate and has the advantages of high efficiency, environmental friendliness and multifunction.
Description
Technical field
The present invention relates to technical field of chemical product manufacture, and in particular to a kind of high effective environmental protection multifunctional cooling water is killed livestock
Agent.
Background technology
In Direct Discharging Type Cooling Water System and part recirculating cooling water system, often there is the numerous in a large number of microorganism and shellfish
Grow, at the same these microorganisms and shellfish can secreting mucus, form biological clay, be attached on the pipeline of system and equipment, reduce
The heat transfer effect of equipment, causes energy consumption to raise；At the same time, biological clay is attached on equipment, forms underdeposit corrosion, is shortened
Service life time of equipment, economic loss is caused to user.In order to eliminate the harm of microorganism and shellfish, at present, market
On processed using all kinds of biocides, but effect is preferable not to the utmost.There is following deficiency in use in these biocides：Kill
Fruit of coming into force is good, but toxicity is big, pollution is big, zest is strong；Toxicity is low, pollution is light, zest is little, but effect is poor, dosage
Greatly, high cost；Product function is single, it is difficult to reaches and can kill shellfish again while sterilization algae removal effect can be played；Especially killing
During shellfish, add such as pesticide additive to strengthen drug effect, effect on environment is very big.Therefore, it is necessary to develop one
The biocide of novel high-efficiency environment friendly is planted to meet market demand.
Content of the invention
It is an object of the invention to provide a kind of high effective environmental protection multifunctional cooling water biocide and preparation method thereof, using 12
Zephiran, ten zephirans be primary raw material, agitated mix, product toxicity
Extremely low, nonirritant, environmental pollution is minimum, action effect is notable, with efficient, environmental protection, multi-functional characteristic.
To achieve these goals, the technical solution used in the present invention is as follows：
