Embodiment 2

[0027] Embodiment 2: the preparation method of composite leather anti-mold and fungicide

[0028] Step 1. Preparation of cyclodextrin inclusion compound: prepare β-cyclodextrin saturated solution and citric acid solution with molar ratio of 1:0.5 β-cyclodextrin and citric acid respectively, and then saturate β-cyclodextrin After the temperature of the solution rises to 40-70°C, then add the citric acid solution into the β-cyclodextrin saturated solution while stirring, and keep stirring for 1-3 hours. After the reaction is complete, cool the mixture to 3-5°C , and insulated and refrigerated for 12-24 hours, filtered and separated to obtain a precipitate, which was washed with deionized water, and vacuum-dried to obtain a β-cyclodextrin inclusion compound.

[0032] Embodiment 3: the preparation method of composite leather anti-mold and fungicide

[0033] Step 1. Preparation of cyclodextrin inclusion compound: prepare β-cyclodextrin saturated solution and ascorbic acid solution with molar ratio of 1:2 β-cyclodextrin and ascorbic acid respectively, and then make β-cyclodextrin saturated solution After the temperature rises to 40-70°C, add the ascorbic acid solution into the β-cyclodextrin saturated solution while stirring, and keep stirring for 1-3 hours. After the reaction is complete, cool the mixture to 3-5°C and keep it warm Refrigerate for 12-24 hours, filter and separate to obtain a precipitate, wash the precipitate with deionized water, and dry in vacuum to obtain a β-cyclodextrin inclusion compound.

Abstract

The invention discloses a mildew-proof and degerming agent for composite leather. The mildew-proof and degerming agent is prepared from chlorite, a cyclodextrin inclusion compound, modified silver-loaded zirconium phosphate, a stabilizer, a regulator and a drying agent. Compared with the prior art, the mildew-proof and degerming agent for the composite leather and a preparation method thereof have the advantages that produced chlorine dioxide gas can enter microorganisms to act on an enzyme and is used for inhibiting the synthesis of protein and inhibiting specific adsorption of bacteria; meanwhile, the chlorine dioxide gas reacts with amino acids in one part of microorganism protein and reaction products are decomposed and destroyed to cause the death of bacteria; the cyclodextrin inclusion compound is introduced so that the releasing time of the chlorine dioxide can be adjusted and a long-acting slow-release mechanism is formed; the mildew-proof and degerming agent has the characteristics of mildew-proof and sterilization properties, lasting property and stability, can be biologically degraded and is green and environmentally friendly; the modified silver-loaded zirconium phosphate is introduced and hole neutral surfaces of silver ions and zirconium phosphate are in bond joint effectively through a modifier and a bonding force between a carrier and the silver ions is effectively enhanced, so that the mildew-proof and degerming agent has the advantages of ultraviolet illumination resistance, high temperature resistance, lasting antibacterial capability and the like.

Description

technical field [0001] The invention relates to the field of anti-mold and antibacterial, in particular to a composite leather anti-mold and antibacterial agent and a preparation method thereof. Background technique [0002] Leather shoes are very easy to mold in wet seasons. In addition to making leather shoes go bad, moldy, and damaged, molds bring great economic losses to footwear production and sales companies, and their spores spread into the air and pollute the environment. Wearing moldy shoes can also easily lead to the occurrence of athlete's foot, endangering human health. The impact of mold on the quality of leather shoes is mainly manifested in the following aspects: (1) the pigmentation of the mold on the leather shoes, that is, the formation of stains; (2) the growth of the mold makes the dyeing and finishing of the leather shoes uneven; (3) The mold forms oily frost on the leather shoes; (4) the mold can degrade the leather fiber; (5) the mold can also destroy...
