Abstract
The invention discloses a kind of non-oxidative antimicrobials, are made of according to weight fraction 80-90 parts of isothiazolinone and 5-10 a part inorganic salts, inorganic salts are selected as the one of which of sodium chloride or potassium chloride.The present invention is using sodium chloride or potassium chloride as stabilizer, and product is pollution-free, and production cost is low, is not susceptible to heavy poly-.
Description
Technical field
The present invention relates to fungicide, in particular to non-oxidative antimicrobial.
Background technique
Water treatment biocide is also known as Biocidal algae-killing agent, sludge remover or anti-pollution mud agent.One kind can inhibit in water bacterium algae and
Microorganism grows, and to form microorganism viscosity mud to prevent, the chemicals to cause damages to system.Including oxidizing bactericide,
Such as chlorine, sodium hypochlorite, bleaching powder, ozone, chloramines；Non oxidizing bactericide, as dodecyl dimethyl benzyl ammonium chloride,
Bromination dodecyl dimethyl hexadecyldimethyl benzyl ammonium, dithiocyano-methane etc.；Heavy metal compound, such as mercury oxide, mercury chloride, mercuric fluoride
Deng；Foundry loam fungicide, such as rosin amine, hydrogen peroxide, again guanidine polymer.
Isothiazolinone is mainly by 5-Chloro-2-methyl-4-isothiazolin-3-one (CIT) and 2- methyl -4- isothiazoline -
3- ketone (MIT) composition.Isothiazolinone is to serve to kill livestock by the key of disconnection bacterium and algae protein matter.Isothiazoline
After ketone is contacted with microorganism, it promptly can irreversibly inhibit its growth, so as to cause the death of microbial cell, therefore to common
Bacterium, fungi, algae etc. have very strong inhibition and killing effect.
Isothiazolinone biocide agent in smelting iron and steel, oil-field flooding, oil plant, thermal power plant, Large Fertilizer Plant, make
Paper plant, light textile, water apply the fields such as coating, industry cleaning link and are also widely applied.
But because isothiazolinone can be decomposed in polar organic solvent such as alcohol or in water, bioactivity meeting
It reduces over time.Therefore, the stability that isothiazolinone is improved in polar organic solvent or water is carried out
Numerous studies.
Metal nitrate, nitrite, formaldehyde are often added in the prior art as stabilizer.Such as publication number
The patent of CN102783482A discloses a kind of 3- isothiazolinone composition, its component and content (weight percent) packet
It includes: 3- isothiazolinone derivatives 20-30%, alkali nitrates 10-25%, alkali metal chloride 1-10%, hydrogen peroxide
0.001-0.02%, the bromo- 2- nitroethyl alcohol 0.005-0.01% of 2,2- bis-, surplus are solvent.
But metal nitrate, nitrite and formaldehyde have certain toxicity in above stabilizer, therefore for human health
Cause certain harm.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to a kind of non-oxidative antimicrobials, are guaranteeing stability
In the case of it is more environmentally friendly.
Above-mentioned technical purpose of the invention has the technical scheme that a kind of non-oxidative antimicrobial, presses
It is made of according to weight fraction 80-90 parts of isothiazolinone and 5-10 a part inorganic salts, inorganic salts are selected as sodium chloride or chlorination
The one of which of potassium.
For the present invention using sodium chloride or potassium chloride as stabilizer, product is pollution-free, and production cost is low, is not susceptible to sink
It is poly-.
Further, inorganic salts are selected as sodium chloride.
Sodium chloride is low as its production cost of stabilizer, and environment friendly and pollution-free.
Further, inorganic salts are selected as potassium chloride.
Potassium chloride is low as its production cost of stabilizer, and environment friendly and pollution-free.
Further, inorganic salts are selected as sodium chloride and potassium chloride, and sodium chloride and potassium chloride are 4:1 according to weight ratio.
Research shows that when sodium chloride and potassium chloride are matched according to weight ratio 4:1, optimal stability.
Further, by mass fraction, isothiazolinone includes the 5- chloro-2-methyl -4- isothiazoline -3 of 30%-40%
- 3 ketone of 2- methyl -4- isothiazoline of ketone and 40%-45%, remaining is 2-n- octyl -4- isothiazoline -3- ketone.
Isothiazolinone includes 5-Chloro-2-methyl-4-isothiazolin-3-one (CIT), 2-methyl-4-isothiazolin-3-one
(MIT), 1,2-benzisothiazolin-3-one (BIT), 2-n- octyl -4- isothiazoline -3- ketone (OIT) etc., different proportion shadows
Its service performance is rung, uses the ratio and type of above range in the present embodiment.
Further, by mass fraction, isothiazolinone include 35% -3 ketone of 5- chloro-2-methyl -4- isothiazoline and
45% -3 ketone of 2- methyl -4- isothiazoline, remaining is 2-n- octyl -4- isothiazoline -3- ketone.
The isothiazolinone performance of above-mentioned mass fraction is best.
In conclusion the invention has the following advantages: the present invention effectively promotes the stability of fungicide, and environmental protection.
