Abstract
The invention discloses a mildew-proof agent for a straw weaving product. The mildew-proof agent comprises three raw materials, including sodium diacetate, benzimidazole and sodium benzoate. When in use, the three raw materials can be mixed, and then water is added to the raw materials to prepare a mixed solution, or a solution of the three raw materials is prepared into a mixed solution accordingto a proportion; a straw weaving product which needs mildew proofing is soaked by the mixed solution; and then the product is naturally aired. The compound mildew-proof agent has the characteristicsof low price and convenience, is widely used and can have an effective protective action on products which are easy to have mildews, such as the straw weaving products and the like. Particularly, thesodium diacetate is used as the main component, thus the mildew-proof agent has no toxic and side effects.
Description
Technical field
The present invention relates to a kind of mould inhibitor, particularly a kind of mould inhibitor that is applicable to hay, straw weaving product.
Background technology
In China, the particularly southern much straw plaited technology of provinces and cities, with a long history, great variety of goods, fancy is various, especially the knitting that is primary raw material with the yellow grass of triangle is the exquisitest, smooth pliable, strong but pliable in texture, have manufacturability and practicality concurrently, for the green non-pollution environmentally friendly machine, has vast potential for future development.But region on the south the middle and lower reach of Yangtze River, annual summer, particularly after the set-in of plum rains, temperature raise gradually, overcast and rainy, heavy rain is continuous constantly, it is warm that there was dampness in the air, and this natural environment is fit to growth and the breeding of various moulds, already caused very big loss for straw plaited, limited the production capacity of straw weaving product, the production in enterprise is in the process that stores and sell, the straw weaving product that hygroscopicity is stronger goes mouldy easily, causes damage.Annual because going mouldy of straw weavings caused serious loss to the straw plaited industry, use lot of manpower and material resources to remove mildew on the straw weavings, also some is seriously scrapped owing to going mouldy.
Mold-proof method is as from adopting quicklime charcoal, ash etc., and developing into present employing calcium chloride, silica gel etc. carries out the moisture absorption, from simple and crude fan blower, ventilating fan cooling, develops into till now sealed storage and modern means such as air conditioner, dehumidifier dehumidifying.Use the requirement of chemical anti mildew agent comparatively strict, possess both mould fungus inhibition growths simultaneously, nontoxic to animal again.Therefore, necessarily require mould inhibitor must have stronger broad-spectrum antibacterial effect; Easy to operate, safe in utilization, economical, no carcinogenic, teratogenesis, mutagenesis.
At present, Chang Yong mould inhibitor mainly contains three major types: the first kind is an organic acid, as propionic acid, sorbic acid, benzoic acid, acetate, dehydroacetic acid and fumaric acid etc.; Second class is organic acid salt and ester thereof, as propionate, sodium sorbate (potassium), Sodium Benzoate and dimethyl fumarate etc.; The 3rd class is a composite mildew inhibitor.The organic acid anti-mold effect is better but corrosivity is bigger; The organic acid salt anti-mold effect is poor than organic acid, and must just can carry out under the condition that certain moisture and pH value are arranged, but corrosivity is little; The effect of composite mildew inhibitor anti-mold effect is strong, corrosivity is little, is the development trend of mould inhibitor.The mechanism of action of mould inhibitor mainly is with the form destroy microorganisms cell of unionized molecule and cell membrane or intracellular enzyme; zymoprotein in the mould is lost activity and catalysis can not be participated in; with the propagation of inhibition microorganism and the generation of toxin, thus the quality of protection feed.Suppress the active of microbial cell internal respiration enzyme and hinder the condensation reaction of acetylcoenzyme as benzoic acid, and tricarbonic acid cycle is obstructed, metabolism is influenced, but and the saturating property of block cell film; Sorbic acid can combine with sulfydryl in the biology enzyme system, thereby the destructive enzyme system reaches bacteriostasis.In addition, organic acid also forms uniform organic acid diaphragm on the feed surface, prevents that mould from multiplying.But these mould inhibitors can not adapt to fully to the climatic characteristic of the sultry humidity in summer, mildew-resistant effect limited, the generation that can not be in full force and effect prevent gone mouldy.
Summary of the invention
The invention provides a kind of special composite mildew inhibitor at straw weaving product, mould inhibitor can be penetrated in the cell of herbaceous stem, thereby eliminates various moulds completely.
A kind of mould inhibitor that is used for straw weaving product is made up of sodium Diacetate, benzimidazole and three kinds of raw materials of Sodium Benzoate.
Each components contents in the mould inhibitor, in parts by weight:
Sodium Diacetate 0.3-3 part
Benzimidazole 0.1-0.5 part
Sodium Benzoate 0.5-1 part
A kind of preferred mould inhibitor is 1: 1 by weight ratio:: 1 sodium Diacetate, benzimidazole and Sodium Benzoate are formed, and anti-mold effect is obvious.
Another kind of preferred mould inhibitor, in parts by weight, form by 1-2.5 part sodium Diacetate, 0.1-0.2 part benzimidazole and 0.5-1 part Sodium Benzoate, also can reach tangible anti-mold effect, and (such as, the benzimidazole that Chemical Reagent Co., Ltd., Sinopharm Group produces) price is more expensive because benzimidazole, reduce its consumption, can reduce cost.
The mechanism of action of mould inhibitor mainly is with the form destroy microorganisms cell of unionized molecule and cell membrane or intracellular enzyme, zymoprotein in the mould is lost activity and catalysis can not be participated in, and with the propagation that suppresses microorganism and the generation of toxin, thus mildew-proof function.The advantage of Sodium Benzoate is that price is low, the source is abundant, good, the no cumulative effect of effect, toxicity little (greater than sorbic acid and salt thereof); Shortcoming is very narrow to the requirement of pH value, can only play a role under acid condition, and the pH value begins to descend greater than 4 o'clock mildew-proof functions, and disagreeable tastes such as bitterness are arranged.The precursor structure of benzimidazole bactericide is the active part that contains the benzimidazole ring, fungicidal spectrum is wide, except that oomycetes, better to effects such as botrytis, sickle-like bacteria, sclerotinite, verticillium sp, rhizoctonias, but multiple pathogen wheat scab, bakanae disease of rice, fruit vegetable gray mold and beet, leaf spot of peanut are developed immunity to drugs to it.And sodium Diacetate mainly is that the interaction of interferases has suppressed the generation of mould by the cell wall that infiltrates through mould effectively, thereby reaches efficient mildew-resistant, function such as anticorrosion, to the inhibition effect excellence of black bent poison, bread mold, aspergillus flavus, Trichoderma viride.
The action principle of sodium Diacetate, benzimidazole and Sodium Benzoate has nothing in common with each other, and can kill and inhibitory action from different aspects to the mould generation, thereby reach wide spectrum, long-acting mildew-resistant anti-mildew effect.
Mould inhibitor of the present invention adds water after three kinds of raw materials can being mixed and is made into mixed solution, or the solution of three kinds of raw materials is prepared by measuring than being mixed with mixed solution in use, will need the straw weaving product of mildew-resistant to soak with mixed solution, and natural air drying gets final product then.
The present invention forms composite mildew inhibitor by sodium Diacetate, benzimidazole and three kinds of raw materials of Sodium Benzoate; have cheapness characteristics easily, widely applicable, can play effective protective effect to easy mouldy products such as straws plaited; particularly utilize sodium Diacetate to be main component, do not have toxic and side effect.
