Abstract
The invention relates to an isothiazolinone composition. The isothiazolinone composition is characterized by comprising 1 to 15wt% of a 3-isothiazolinone compound, 0.05 to 0.2wt% of bispyrithione, 0.2 to 5wt% of 1,3,5-triazaphosphorine and the balance of one or more solvents. The isothiazolinone composition has excellent stability, does not contain inorganic salts and organic solvents, can be used in a dispersion solution or an emulsion or latex, has a wide application range and can effectively inhibit growth of harmful microorganisms.
Description
Technical field
The present invention relates to a kind of bactericide, particularly a kind of isothiazolinone composition.
Background technology
Iso thiazoline ketone compound is a kind of novel wide-spectrum bactericide, have efficient, wide spectrum, low toxicity, in the environment can the advantage such as natural degradation, be widely used in Treatment of Industrial Water, industrial oil additive, building materials be anticorrosion, electric power is metallurgical, oilfield chemical, leather, paint, weaving, printing and dyeing, daily use chemicals, cosmetics, papermaking, the field such as emulsion.But iso thiazoline ketone compound Problems existing is: long-term storage performance is stable not, As time goes on biologically active can reduce, and affects the effect of bactericide, and conventional solution adds stabilizing agent in iso thiazoline ketone compound.
US Patent No. 3870795 discloses a kind of method using metal nitrate or metal sulphite to make 3-isothiazolinone solution-stabilizedization, the method stablizes 3-iso thiazoline ketone compound, to improve the stability of 3-iso thiazoline ketone compound in polar solvent or water by interpolation alkaline earth nitrate, alkali metal nitrites salts.Adopt inorganic salts as stabilizing agent, when with latex product compatibility, latex there will be solidification phenomenon; The isothiazolinone composition of saliferous, because there is corrosion and problem inconsistent with non-aqueous media, the scope of application is restricted.
At present, also have and adopt organic matter as stabilizing agent, as US Patent No. 4165318 discloses a kind of coating composition of formaldehyde used as stabilizers, propose interpolation formaldehyde or Form aldehyde release body as stabilizing agent.US Patent No. 4824957 discloses a kind of stabilization method of anhydrous isothiazolinone, propose in isothiazolinone formula, add hydroxyl organic solvent as stabilizing agent.European patent EP 0315464 discloses a kind of stabilization method of isothiazolinone composition, mentions the stabilizing agent can making 3-isothiazolinone with orthoformate.European patent EP 0342852 discloses a kind of organic matter stabilizing agent, mentions the stabilizing agent can making 3-isothiazolinone with epoxides.
In iso thiazoline ketone compound, add organic matter stabilizing agent is not highly stable, easily spontaneous formation precipitation; Due to the oxidizing matter of these stabilizing agents, inconsistent problem can be there is with during other components compatibilities; In addition formaldehyde or Form aldehyde release body are poisonous and harmful substances, are unfavorable for promoting the use of.
Summary of the invention
The object of the present invention is to provide a kind of stable performance, isothiazolinone composition applied widely.
Technical solution of the present invention is: a kind of isothiazolinone composition, it is characterized in that its component and content (percentage by weight) are: the 3-iso thiazoline ketone compound 1 ~ 15% be made up of CMIT and MI, Bispyrithione 0.05% ~ 0.2%, 1,3,5-Trianacyclohexane 0.2 ~ 5%, surplus are water.
The content of described 3-iso thiazoline ketone compound is preferably 10 ~ 15%.
Isothiazolinone composition provided by the invention, have employed Bispyrithione as stabilizing agent, adding of Bispyrithione can make 3-iso thiazoline ketone compound have excellent stability, precipitation is there is not in system, due to not containing mineral salt, be specially adapted in emulsion or latex and solidification phenomenon do not occur.
Advantage of the present invention is: have excellent stability, do not add mineral salt and organic solvent in component, and can stably be used in dispersion liquid or emulsion or latex, wide accommodation, effectively suppresses harmful microbe growth.
Embodiment
The process for preparation of 3-isothiazolinone composition of the present invention is: neutralized with 1,3,5-Trianacyclohexane in water by 3-iso thiazoline ketone compound, its pH value is 2.0-3.0, adds Bispyrithione, and stir to obtain 3-isothiazolinone composition product.
Composition and the content of preparation 3-isothiazolinone composition are shown in table.
3-iso thiazoline ketone compound in component is the mixture of CMIT and MI, ratio (weight ratio) is between the two 1:100 to 100:1, preferred proportion is 1:10 to 10:1, and most preferred ratio is 3:1.
Solvent in component is water.
By the 3-isothiazolinone composition that the component in above-described embodiment and content are prepared, deposit under 60 DEG C of conditions and within more than 30 days, do not observed precipitation formation.Analyze principle active component CMIT (being called for short CMIT) with high performance liquid chromatography (HPLC), the concentration of MI (being called for short MIT), the results are shown in following table.
Experimental result shows, 3-isothiazolinone composition has good stability, can place 30 days content substantially constant under the condition of 60 DEG C.
Claims (2)
1. an isothiazolinone composition, it is characterized in that its component and content (percentage by weight) are: the 3-iso thiazoline ketone compound 1% ~ 15% be made up of CMIT and MI, Bispyrithione 0.05% ~ 0.2%, 1,3,5-Trianacyclohexane 0.2% ~ 5%, surplus are water.
2. require a kind of isothiazolinone composition described in 1 as requested, it is characterized in that the content of described 3-iso thiazoline ketone compound is preferably 10 ~ 15%.
