Preparation method of compound leather bactericidal and mildew-proof agent

Abstract

The invention aims to provide a compound leather bactericidal and mildew-proof agent, and in particular provides a preparation method taking the composition of a guanidine compound, 2-bromo-2-nitro-1,3-propanediol, 3-iodo-2-propynyl butylcarbamate, ethylenediaminetetraacetic acid (EDTA) B, a corrosion inhibitor, ethanol and water as the compound leather bactericidal and mildew-proof agent. The compound leather bactericidal and mildew-proof agent comprises the following components by mass percent: 1-15% of guanidine compound, 0.05-3% of EDTA B, 0.1-2% of 2-bromo-2-nitro-1,3-propanediol, 1-50% of ethanol, 0.05-5% of 3-iodo-2-propynyl butylcarbamate, 0.1-20% of corrosion inhibitor and the balance of water. The preparation method is characterized by comprising the following steps of: mixing the guanidine compound, the 2-bromo-2-nitro-1,3-propanediol and the EDTA B with 50% of water by mass percent, and stirring the mixture for 3 hours to prepare a mixture A; mixing the 3-iodo-2-propynyl butylcarbamate, the corrosion inhibitor and the ethanol with the residual 50% of water by mass percent, and stirring the mixture for 3 hours to prepare a mixture B; and stirring the mixture A and the mixture B to react for 2 hours, then standing for 2 hours, determining the content of the mixture of the mixture A and the mixture B, and packaging the qualified mixture, thus obtaining a qualified product. The invention also aims to dilute the compound leather bactericidal and mildew-proof agent, and the dilution ratio is 50-500 times.

Description

technical field [0001] The invention belongs to the field of disinfection and sterilization products, and relates to a compound sterilization and anti-mildew preparation of leather, especially a preparation of guanidine compounds, 2-bromo-2-nitro-1,3-propanediol, iodopropynyl carbamic acid The composition of butyl ester, Torlon B, corrosion inhibitor, ethanol and water is used as a compound fungicide and antifungal agent for leather. Background technique [0002] Leather raw materials are rich in nutrients such as protein and fat, which are easily invaded by microorganisms during storage, and are prone to mildew during processing. hotbed. [0003] The porosity and polar structure of the leather structure make it easy to absorb moisture and make the leather acidic. These factors constitute the basic conditions for mildew. Mildewed leather shows white, blue and black colonies and stains. The mold on the surface will develop into the interior of the leather over time, affecti...
