Abstract
The invention relates to a novel composite bactericide, which is characterized in that two quaternary ammonium salt bactericides of alkyl benzyl ammonium chloride and dialkyl dimethyl ammonium chloride (A) are simultaneously contained in the bactericide composition, and the weight ratio of A to B is 1: 1-1: 100. The composite bactericide has the characteristics of small dosage and difficult generation of drug resistance of bacteria when being applied to an industrial circulating cooling water system, has a corrosion inhibition effect on metals, cannot corrode the metals, and has a good synergistic effect with a corrosion and scale inhibitor.
Description
Technical field
The present invention relates to a kind of Biocidal algae-killing agent that is mainly used in the industrial circulating cooling water system, particularly a kind of compound disinfectant that contains quaternary ammonium salt.
Background technology
Breeding with Biocidal algae-killing agent inhibition, killing microorganisms is well-known.In industrial circulating cooling water system, along with the raising of cooling water cycles of concentration, the breeding of microorganism will aggravate, and algae and microorganism viscosity mud can stop up the pipeline of water cooling equipment or the heat exchange efficiency of water cooling equipment is reduced, thereby influence industrial production.For suppress, killing microorganisms and algae, the normal method that adds Biocidal algae-killing agent that adopts.
Biocidal algae-killing agent list agent commonly used at present has chlorine, chlorine dioxide, clorox, quaternary ammonium salt, glutaraldehyde etc.The method that the agent of Biocidal algae-killing agent list adopts two kinds of medicaments alternately to add in use mostly, dosage are mostly more than 50mg/l, and microorganism easily produces drug resistance; Composite sterilization algicide has isothiazolinone and copper sulphate compound disinfectant etc.Wherein isothiazolinone and copper sulphate compound disinfectant contain copper ion, can cause corrosions of metal such as aluminium, iron when using in recirculated cooling water; United States Patent5,611,938 have introduced the composite sterilization algicide of quaternary ammonium salt and chlorine dioxide, its best sterilizing rate is 99.9%, but this kind quaternary ammonium salt and chlorine dioxide compound disinfectant easily make the active ingredient of corrosion inhibiting and descaling agent in the water system lose efficacy because chlorine dioxide has strong oxidizing property.
Summary of the invention
The object of the present invention is to provide a kind of novel compound disinfectant, adding less when using in industrial circulating cooling water system, bacterium is difficult for producing drug resistance, and medicament itself has corrosion inhibition to metal, can not cause corrosion, good synergistic function be arranged with corrosion inhibiting and descaling agent to metal.
Compound disinfectant of the present invention is made up of following two class quaternary ammonium salts:
The two alkyl-dimethyl ammonium chlorides of A,
B alkyl benzyl ammonium chloride.
Two alkyl-dimethyl ammonium chlorides (A) are as a kind of cationic surfactant, it can reduce the transmissibility of cell wall, when it contacts with microorganism, when destroying or disturbing nutriment to enter in the cyton, also influence the discharge of refuse in the cyton, thereby cause the sex change of microbial body internal protein, make its metabolism disequilibrium and cause microorganism to be in death by suffocation or suppress its growth.
Hydrophobic grouping in the alkyl benzyl ammonium chloride (B) and hydrophilic radical can infiltrate the lipoid layer and the protein layer of microbial cell film respectively, thereby change the permeability of microbial cell serous coat, and intracellular matter is exosmosed, and cause cell death; It can also destroy the phospholipid substance in the bacterial cell plasma membrane in addition, causes endolysis, thus killing bacteria.If with A and B composite after, by the synergistic effect between medicament, both can improve antibacterial activity effectively, can avoid again using the bactericide of single variety for a long time and make the microorganisms pesticide resistance.
Wherein, the weight ratio of A and B is 1: 1 to 1: 100, and optimum proportioning is 1: 1 to 1: 25.Actual weight ratio can be determined according to the cooling water system total number of bacteria.
Two alkyl in two alkyl-dimethyl ammonium chlorides of indication of the present invention are preferably two C
1-C
20, that wherein performance is best is two C
8-C
10Alkyl in the alkyl benzyl ammonium chloride is preferably C
1-C
20, that wherein performance is best is C
10-C
16
Compound disinfectant of the present invention is mainly ferrous metal to metal material certain corrosion inhibition.
When compound disinfectant of the present invention used as Biocidal algae-killing agent, the 20mg/l that comes into operation, the bacterial inactivation rate after 24 hours were that the killing rate of bacterium is that bacterial inactivation rate is 99.0% after 99.9%, 72 hour after 100%, 48 hour.When product of the present invention does not use 20mg/l separately with the corrosion inhibiting and descaling agent effect, to 20
#The corrosion inhibition rate of steel is more than 40%.Have adding less when in industrial circulating cooling water system, using, bacterium is difficult for producing chemical sproof characteristics, and medicament itself has corrosion inhibition to metal, can not cause corrosion to metal, and good synergistic function is arranged when using simultaneously with corrosion inhibiting and descaling agent.
