Description
Technical field
The present invention relates to a kind of preparation method of mould inhibitor, especially a kind of preparation of chitosan Leather mildew-proof new material
Method.
Background technology
As the improvement of people's living standards, the dosage of leather is increasing.But the raw material skin used in tanning production is rich
Containing nutriments such as protein, fat, during preservation, the intrusion of microorganism is highly susceptible to.By processing into
Leather, although increased to the resistance of microorganism, still can go mouldy, especially induce one largely to use in leather production process
The fatting agent of natural oil production, they are also the hotbed of microbial growth procreation.In addition, porous and the pole of leather structure
Property structure make its easy moisture absorption, leather is in acidity.All above reasons constitute mouldy primary condition.The leather and fur products to mildew
The bacterium colony or color spot of white, blueness, yellow and black occurs, the mould on surface is developed into leather simultaneously, makes the resistance to of leather
Mill, intensity and elasticity are also affected.So mould will cause seriously to damage to the outward appearance and inherent quality of leather and leather products
Evil, it is mould proof be in leather industry it is very important because leather be natural polymer (collagen) processing production
Product, it is adapted to the growth of microorganism, particularly leather shoes, the leather goods maximum as consumption figure are more sharp due to reasons such as sweat and dusts
In the growth of fungi, therefore, leather goods are also required to assign antibacterial in use as textile and public utility etc.
Property, to suppress the growth of bacterium, fungi and virus etc..
CN102318624B discloses a kind of water-fast leather and fur products antimildew and antibacterial agent and its manufacture method.The water-fast skin
Leather goods antimildew and antibacterial agent, its composition are by weight ratio：Mould inhibitor 1-6.5%, antiseptic 2-5%, bleeding agent 1-4%, point
Scattered emulsifying agent 1-4%, thickener 1-3%, antifreezing agent 2-5%, defoamer 0.05-0.1%, solvent complement to 100%.
CN102396515B discloses poly- guanidine durability leather antibacterial agent of a kind of branching type organosilicon and preparation method thereof,
It is made up of the intermediate with branched structure, polyamine, guanidine hydrochloride and low molecule organosiloxane.Wherein, in branched structure
The molal quantity of mesosome is 0.1~1.2, polyamine molal quantity is 0.3~8.0, guanidine hydrochloride molal quantity is 0.5~5.0, low molecule has
The molal quantity of organic siloxane is 0.1~3.0.
Existing leather fungicide product mostly using have the organic matter of antibacterial effect or heavy metal silver as effective antibacterial into
Point, and leather and fur products has many long-term fitting human bodies, it is unfavorable to health.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of preparation method of chitosan Leather mildew-proof new material, its
Preparation method is realized by following steps：
By weight, carboxymethyl chitosan, the capronate of ethene two (ethoxy ethylene) two, 1,3- adamantane are added in a kettle
Omega-diol diacrylate, disilicic acid yttrium salt, N- sulfonic acid butyl-pyridinium tosilate ionic liquids, calcium lignosulfonate, ethanol,
Benzoyl peroxide, gelatin, 80-90 DEG C is warming up to, 2-4h is stirred with 200-300rpm rotating speed, that is, obtains chitosan leather and prevents
Mould new material.
The described capronate of ethene two (ethoxy ethylene) two, its quality dosage are the 1-3% of carboxymethyl chitosan.
Described 1,3- adamantane omega-diol diacrylates, its quality dosage are the 1-3% of carboxymethyl chitosan.
Described disilicic acid yttrium salt, its quality dosage are the 0.1-0.5% of carboxymethyl chitosan.
Described N- sulfonic acid butyl-pyridinium tosilate ionic liquids, its quality dosage are the 0.1- of carboxymethyl chitosan
0.3%。
Described calcium lignosulfonate, its quality dosage are the 0.1-0.3% of carboxymethyl chitosan.
Described ethanol, its quality dosage are the 150-250% of carboxymethyl chitosan.
Described benzoyl peroxide, its quality dosage are the 0.1-0.5% of carboxymethyl chitosan.
Described gelatin, its quality dosage are the 1-5% of carboxymethyl chitosan.
Described carboxymethyl chitosan, the capronate of ethene two (ethoxy ethylene) two, 1,3- adamantane glycol diacrylate
Ester, disilicic acid yttrium salt, N- sulfonic acid butyl-pyridinium tosilate ionic liquids, calcium lignosulfonate, ethanol, benzoyl peroxide
It is commercially available prod.
The invention has the advantages that：
The Antibacterial Products that the present invention is produced, main component is carboxymethyl chitosan, its good biocompatibility, bactericidal effect
By force, harm to the human body is small；Antiseptic each component is uniformly dispersed, the sustainable time length of bactericidal effect.
