Abstract
The invention discloses a water-soluble mildew preventive and a preparation method thereof. The 3-iodine-2-propynyl butylcarbamate is taken as a raw material, propylene glycol, polyethylene glycol 200 or polyethylene glycol 400 is taken as a solvent, coconut oil alkanolamide and fatty alcohol-polyoxyethylene (10) ether are taken as surfactants, and the solubility of the mildew preventive in an aqueous system is enhanced. The mildew preventive has strong sterilization function on aspergillus niger, aspergillus flavus and most of molds, has long-term inhibiting effect, can be applied to the fields of hygienic products, leather, daily products and the like, and is a water-soluble novel mildew preventive with the advantages of wide application range, safety and environmental protection.
Description
Technical field
The present invention relates to a kind of mould inhibitor and preparation method thereof, specifically a kind of is water-soluble high-effective antimold of main component and preparation method thereof with 3-iodo-2-propynyl butyl carbamate.
Background technology
Detrimental microorganisms can be brought a lot of diseases to the mankind, serious harm people's life security.Mould has brought great puzzlement to us as a kind of common microorganism in people's life, therefore seek a kind of mould inhibitor efficiently and be very important.Mould inhibitor in the past is often more weak to the inhibition effect of mould, can certain injury be arranged to human body again during heavy dose of the use, therefore in the world always at the mould inhibitor of development of new.3-iodo-2-propynyl butyl carbamate is exactly a kind of novel mould inhibitor, and it has the effect that extraordinary mould fungus inhibition is produced, and it is to the minimum inhibitory concentration of common mould 1～5mg/l only, well below the consumption of mould inhibitor commonly used.
Though 3-iodo-2-propynyl butyl carbamate has extraordinary antibacterial effect, but also there is the shortcoming of poorly water-soluble in it simultaneously, we practical test result show, the solvability in the time of 25 ℃ in its water less than 100,000/, so it can not directly use in water-soluble protective system.
Summary of the invention
The present invention seeks to the shortcoming that in water-soluble protective system, can not directly use at 3-iodo-2-propynyl butyl carbamate, developing a kind of 3-iodo-2-propynyl butyl carbamate is water-soluble high-effective antimold of main component and preparation method thereof, have totally nontoxic, non-stimulated, the characteristic of not having corrosion and safety and environmental protection simultaneously, can be widely used in the mildew-resistant of various products aspects such as amenities, leather, textile.
The concrete technical scheme that realizes the object of the invention is:
A kind of water-soluble mildew preventive, comprise following main component: the 3-iodo-2-propynyl butyl carbamate that accounts for gross weight 8%～10%, account for propane diols, Macrogol 200 or the PEG400 of gross weight 20%～50%, account for the cocoa butter alkanolamide of gross weight 10～40%, account for aliphatic alcohol polyethenoxy (10) ether of gross weight 10～40%.
3-iodo-2-propynyl butyl carbamate is the component of mould fungus inhibition growth, its sterilization can be elecrtonegativity cells of microorganisms film strong effect usually, destroy microorganisms storage power and nutrient are carried necessary ion gradient, even cause the endochylema seepage, thereby kill mould.
Propane diols, Macrogol 200 or PEG400 are to be used for dissolving the reasonable solvent of 3-iodo-2-propynyl butyl carbamate, and the solvability of 3-iodo-2-propynyl butyl carbamate in propane diols, Macrogol 200 or 400 is greatly about about 20%.Polyethylene glycol that it should be noted that the bigger degree of polymerization can become solid under the low slightly situation of temperature, inconvenience is used.
Surfactant is to be used for effectively increasing the solvability of 3-iodo-2-propynyl butyl carbamate in water, cocoa butter alkanolamide and aliphatic alcohol polyethenoxy (10) ether can have more good effect when using simultaneously, can satisfy the working concentration in water solution system fully.
A kind of preparation method of mould inhibitor, comprise following concrete steps: the 3-iodo-2-propynyl butyl carbamate of certain deal is mixed with propane diols, Macrogol 200 or the PEG400 of corresponding deal, being stirred to 3-iodo-2-propynyl butyl carbamate dissolves fully, add cocoa butter alkanolamide and aliphatic alcohol polyethenoxy (10) ether again and also stir at normal temperatures, to colourless or yellowish clear solution, stop.
Compared with prior art, the water-soluble high-effective antimold of the present invention uses novel in the world mildew-resistant composition 3-iodo-2-propynyl butyl carbamate to be primary raw material, cooperate appropriate solvent and surfactant, strengthened its solvability in water-based system, most moulds such as black-koji mould, Aspergillus flavus there is powerful killing action, and has long inhibitory action.According to the result of our test, it is consumption just growth of energy mould fungus inhibition when 10～50mg/l in water-based system.It also has totally nontoxic, non-stimulated, the characteristic of not having corrosion and safety and environmental protection, can be applied in fields such as amenities, leather, daily use chemicals, is a kind of water-soluble novel mildew resistant agent of widely applicable, safety and environmental protection.
Embodiment
Among the embodiment of the following stated, except that specializing, inventory all is meant weight.
Embodiment one
With 8 parts of 3-iodo-2-propynyl butyl carbamates and 40 parts of mixed with propylene glycol, be stirred to dissolving fully, add 30 parts of cocoa butter alkanolamides and 22 parts of aliphatic alcohol polyethenoxies (10) ether, be stirred to colourless or light yellow transparent solution, get water-soluble high-effective antimold.
Embodiment two
10 parts of 3-iodo-2-propynyl butyl carbamates are mixed with 50 parts of Macrogol 200s, be stirred to dissolving fully, add 25 parts of cocoa butter alkanolamides and 15 parts of aliphatic alcohol polyethenoxies (10) ether, be stirred to colourless or light yellow transparent solution, get water-soluble high-effective antimold.
