Abstract
The invention provides an isothiazolinone disinfecting agent, which comprises 20 to 40 percent of 5-chloro-2-methyl-4-isothiazolinone-3ketone and 8 to 20 percent of 2-methyl-4-isothiazolinone-3ketone. The pH value is between 4.0 and 6.0, and the addition of the disinfecting agent is between 0.5 and 2 ppm. The isothiazolinone disinfecting agent of the invention has low consumption, and can obvious reduce the bacterium content in processing media after being used.
Description
Technical field
The present invention relates to a kind of bactericide, relate in particular to a kind of bactericide of forming by isothiazolinone and derivative thereof.
Background technology
Bactericide is a class water treatment agent very commonly used.In industrial production, especially in the production industry waters such as industrial cooling circulating water system, papermaking, cosmetics, bacterium, the prolific situation of microorganism are very common.The normal operation that a large amount of breedings of microorganism not only can etching apparatus, influence is produced more can reduce water quality, influence product quality.So in industrial production, need often to use bactericide.
Bactericide can be divided into two kinds in water-soluble bactericide and water-insoluble bactericide substantially.Isothiazolinone disinfecting agent is a kind of broad-spectrum high-efficiency and low-toxicity bactericide, its active component isothiazolinone derivatives has extremely strong penetration capacity to the cells of microorganisms film, and, microorganisms such as bacterium common in the industrial and agricultural production, fungi, algae had very strong killing and inhibitory action to cells of microorganisms tissue generation decomposition destruction.Its germicidal efficiency height, safety in utilization is good, environmental nonpollution, non-foam, expense is low.Application: recirculated cooling water, oil-field flooding, agricultural chemicals (fresh-keeping), cutting oil, process hides and leather industry, wood-processing industry, paper-making industry coating and paint, washing agent, cosmetics, photographic film.It is soluble in water, by adopting synthetic isothiazolinone of advanced technologies and derivative thereof to form.The composition of isothiazolinone disinfecting agent commonly used is 5-chloro-2-methyl-4-isothiazoline-3 ketone and 2-methyl-4-isothiazoline-3 ketone now.Commercially available bactericidal effect is not satisfactory by 5-chloro-2-methyl-4-isothiazoline-3 ketone and isothiazolinone disinfecting agent that the 2-methyl-4-isothiazoline-3 ketone is formed, and the sterilization dose that need consume during sterilization is also more.And many isothiazolinone disinfecting agents contain magnesia and magnesium nitrate on the market, have certain toxic pollutant.
Summary of the invention
The object of the present invention is to provide the TLR-01 bactericide that a kind of bactericidal effect is good, toxicity is less, this bactericide is made up of isothiazolinone and derivative thereof.
Technical scheme of the present invention is: a kind of isothiazolinone disinfecting agent, described bactericide contain 5-chloro-2-methyl-4-isothiazoline-3 ketone of 20%-40%:
2-methyl-4-isothiazoline-3 ketone with 8%-20%:
Further, described isothiazolinone disinfecting agent contains 5-chloro-2-methyl-4-isothiazoline-3 ketone of 20%-30% and 2-methyl-4-isothiazoline-3 ketone of 8%-15%.
Be preferably, the pH value of described isothiazolinone disinfecting agent is 4.0-6.0.
Be preferably, the dosage of described isothiazolinone disinfecting agent is 0.5-2ppm.
Further, the dosage of described isothiazolinone disinfecting agent is 1ppm.
In view of different active component proportionings can be brought different bactericidal effects, the present invention makes isothiazolinone disinfecting agent reach better bactericidal effect by regulating the composition proportion of 5-chloro-2-methyl-4-isothiazoline-3 ketone and 2-methyl-4-isothiazoline-3 ketone.
Advantage of the present invention is: adopt 5-chloro-2-methyl-4-isothiazoline-3 ketone and 2-methyl-4-isothiazoline-3 ketone of suitable concentration ratio to be mixed with isothiazolinone disinfecting agent, this bactericide proportioning is stable, do not contain corrosive substance, be easy to store and transportation, adopt less consumption can reach with the identical effect of series bactericidal agent.
Isothiazolinone disinfecting agent of the present invention all can produce stronger sterilization, fungistatic effect in the long period after once dropping into, add a certain amount of bactericide again every certain hour certainly and can further consolidate bactericidal effect; And fungicidal spectrum is wide, can kill the various microorganisms of water system, mould and algae; In operation, do not fire, non-volatile, utmost point low toxicity, can be used with exhausted big number water treatment agents such as ionic, nonionic, have synergistic function; Very easily be degraded into nontoxic little molecule after the use, non-secondary pollution; Good stability: can preserve more than 1 year under the normal temperature.
