Abstract
The invention relates to a high-efficiency moldproof inhibitor for metal working, which comprises the following components in percentage by weight: (a) 42-60% of morpholine compounds, (b) 20-36% of fatty aldehyde, (c) 12-30% of alkanolamide and (d) 8-20% of solvent. The invention mainly solves the problem the metal working fluid fades and smells since bacteria and fungi phagocytize organic substances containing C, H, P and N in the metal working fluid formula in the metal working process. The enzyme inhibitor with favorable compatibility in a water-based or oil-based system is utilized to inhibit the fermentation process of the bacteria and fungi in the metal working fluid environment, and also inhibit the reproductive capacity of the bacteria and fungi in the environment, thereby effectively solving the problems of fading, stratifying, smelling and the like of the working fluid in the metal working process.
Description
Technical field
The present invention relates to a kind of high-efficiency low-toxicity mildew-resistant inhibitor.
Background technology
Add all kinds of base oils in the metal working fluid prescription and comprised long-chain fat alkane, all kinds of lubricant grease and all kinds of surfactants that contain APEO block chain such as paraffinic base, intermediate base, cycloalkyl, these raw materials can both cause growing of bacterium and fungi and Fast-propagation, so must add the mildew-resistant inhibitor in metal working fluid.
Metal processing mildew-resistant inhibitor commonly used has: triazines, formaldehyde and glutaraldehyde, Kathon CG, imidazolone etc., these mildew-resistant inhibitor have the ability of killing fast to bacterium, but fungi is had little effect.In addition, these mildew-resistant inhibitor smells are larger, cause metal process operation environment variation, do not meet the HSE security system.Simultaneously these mildew-resistant inhibitor are in the metal working fluid maintenance process, and biocidal property is poor, and when temperature surpassed 30 ℃ in summer, working fluid easily caused variable color, smelly and when not using for a long time, the easy layering of the bottom of working fluid, smelly.
In recent years, many research institutions are all in the mechanism research of research bactericide and sterilizing ability, but the problem such as it is high all to be faced with Financial cost, and toxicity is large.
Summary of the invention
Technical problem to be solved by this invention is that the mildew-resistant inhibitor toxicity that exists in the conventional art is large, Antifungi weak effect, the defective that Financial cost is too high.The present invention relates to a kind of high-effect anti-mould inhibitor, quick kill bacteria, the Antifungi breeding, little on human body and water body environment impact, and Financial cost is low, is fit to promote the use of.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows: a kind of high-effect anti-mould inhibitor comprises following composition by weight percentage:
(a) 42～60% morpholine kind compound;
(b) 20～36% fatty aldehyde;
(c) 12～30% alkanolamide;
(d) 8～20% solvent.
In the technique scheme, it is characterized in that by weight percentage, contain 42～60% morpholine kind compound in the mildew-resistant inhibitor, can rapid osmotic enter in the cell of bacterium and fungi, mitochondrial respiratory in the cell there is preferably inhibitory action, and anaerobic fermentation is also had good inhibition; Contain 20～36% fatty aldehyde in the mildew-resistant inhibitor, in entering the metal working fluid environment, can kill fast various bacillus and streptococcus, and in post processing, can oxidizedly degrade, environmentally friendly; Contain 12～30% alkanolamide in the mildew-resistant inhibitor, can be in the metal surface film forming, anti-bacteria has certain killing action in the further corrosion of metal surface to anaerobic bacteria; Contain 8～20% solvent in the mildew-resistant inhibitor, improve the compatibility of mildew-resistant inhibitor and water-based and oiliness processing formula.
The used raw material of a kind of high-effect anti-mould inhibitor component that the present invention relates to is as follows:
Morpholine kind compound is main active ingredient, can penetrate in the cell of bacterium and fungi, and the mitochondrial respiratory in the cell is had good inhibitory action, mainly is morpholine class derivative compound; Fatty aldehyde is kill bacteria and fungi fast, mainly is the fatty aldehydes of middle long-chain; Alkanolamide is that the mixture of different structure comprises the tall oil acid acid amides; Solvent is the important carrier that connects prescription Raw and mildew-resistant inhibitor, mainly is ether and alcohols surface-active product.
The alkanolamide of at first synthetic different structure, then with the composite product of morpholine class derivative compound, after will mixing by proportioning weighing solvent, fatty aldehyde at last, the control temperature is observed stability at 50～70 ℃.Detect physical and chemical index.
The mildew-resistant inhibitor that makes as stated above carries out mildew-resistant in constructed experiment suppresses to estimate, and process is summarized as follows:
1, in two 1L wide-mouth bottles, adds respectively metal working fluid (wherein a kind of mildew-resistant inhibitor that do not add).
2, will survey the bacterium sheet clean, dry after and place two wide-mouth bottles.
3, wide-mouth bottle is placed air dry oven, 30 ℃ of constant temperature are measured mouldy the counting on the bacterium sheet every day, and follow-on test is till 7 days.
4, after the follow-on test 7 days, observe in the metal working fluid in two wide-mouth bottles physicochemical property such as colourity, pH value, smell and whether layering.
The present invention adopts harsh Static Assessment Method, has showed good mildew-resistant inhibition in various metal working fluid prescriptions, has obtained preferably technique effect.
The invention will be further elaborated below by embodiment.
