Description
Technical field
The present invention relates to fungicide fields, and in particular to control bacterium composite bactericide and its preparation side under a kind of Acid-Base System
Method.
Background technique
Fungicide is also known as biocide, Biocidal algae-killing agent, microbicide etc., and typically referring in industrial bactericide can be effective
The chemicals of ground control or kill microorganism -- bacterium, fungi and algae.By studying for a long time, facts proved that current
Fungicide can substantially be divided into oxidizing bactericide and non oxidizing bactericide two major classes.Oxidizing bactericide can make protein
Denaturation mainly reaches sterilization purpose and oxidation occurs with bacterial body intracellular metabolite enzyme.Non oxidizing bactericide is mainly
Complex compound sediment is formed with certain components of bacterium after the internal of bacterium can be penetrated into or hydrolyzed in water to kill to reach
It goes out or inhibits the purpose of bacterium.But the difficulty of processing of non oxidizing bactericide is larger, is possible to after Disinfection Effect and use
The extent of injury caused by human body is difficult to control.
Method using most common non oxidizing bactericide is that quaternary ammonium salt is added into basis material, is asked there are following
Topic: the pH value and water quality of use environment will affect the effect for being added to the fungicide of quaternary ammonium salt；In alkaline solution, sterilization
Effect is most strong, but when PH=3, the effect of fungicide is worst.Add the fungicide of quaternary ammonium salt due to suction-operated, has carried out
High concentration thimerosal kills in Experiment on Microbiology, its inhibiting effect to microorganism can not be reduced with dilution method；The sterilization of quaternary ammonium salt
Agent in use, if accidentally being swallowed by children, or is rubbed on skin, can all be threatened to the health of body.

72 parts of isopropanols, 4 parts of lauryl sodium sulfate, 5 parts of sodium xylene sulfonates, 0.8 part of polyvinyl alcohol, 2 parts of vegetable oil acids,
0.2 part of virginiamycin, 1 part of non-oxidative bactericide and 15 parts of ethyl alcohol.
3. a kind of preparation method of the control bacterium composite bactericide under Acid-Base System of any of claims 1 or 2, which is characterized in that
The following steps are included:
Step 1: component each in formula is weighed, by lauryl sodium sulfate or sodium xylene sulfonate and polyvinyl alcohol
It is put into reaction kettle, is stirred under normal pressure, at 90-150 DEG C, time control is completed each in 20-90min for temperature control
Chemical reaction between material；
Step 2: virginiamycin is added in mixed material into step 1 and is uniformly mixed material；
Step 3: the mixed material for obtaining step 2 under the conditions of 70-150 DEG C of temperature is stirred 30-150min, stirring
Room temperature is down to after uniformly；
It is adequately mixed Step 4: the material in step 3 is put into ethanol solution, mixing is completed to be placed on cool place
At dry；
Step 5: the vegetable oil acid is put into ethanol solution, adequately fusion and high-speed stirred are carried out, it will be in step 2
Obtained material mixed solution is added in the ethanol solution calculated containing vegetable oil, obtains the semi-finished product of fungicide；
Step 6: non-oxidative bactericide is added in the semi-finished product of fungicide into step 5, it is sufficiently mixed；
Step 7: carrying out the semi-finished product of fungicide mixing and emulsifying 1-4 hours under conditions of 20-80 DEG C, it is down to room temperature
Obtain finished product.
Step 8: carrying out all-round property testing to the fungicide prepared in step 7.
