Multifunctional leather corrosion inhibitor

Abstract

The invention pertains to leather preservative technical field, in particular to a multipurpose leather preservative. The preparation method of the preservative is that the weight percentage of raw materials is 80 to 92 percent of sodium chloride, 1.5 to 5.0 percent of sodium carbonate, 1.0 to 5.0 percent of sodium sulfite, 1.0 to 4.0 percent of sodium fluosilicate, 1.0 to 4.0 percent of refined naphthalene and 0.7 to 2.0 percent of dipterex; during the preparation process, the first three materials are grinded and screened to equal or lesser than 3mm particles, and then the product can be obtained after six proportioned materials are blended. The preservative can effectively overcome the defect of prior art, effectively restrains the leather autolytic effect, effectively avoids the infringement to leather caused by the cod micrococcus and other insects and microorganism, reduces the raw material loss of leather storing, and can be stored for two years.

Description

1. Technical field [0001] The invention belongs to the technical field of leather antiseptic, in particular to a leather antiseptic with multiple functions. 2. Technical background [0002] Leather anti-corrosion has always been a headache in the leather manufacturing industry, and it is also something that has to be faced. The existing leather anti-corrosion methods include drying method, salting method, salt drying method, freezing method, radiation method, and organic solvent dehydration method. Wait. Drying, salting and salt-drying methods all exist, which cannot effectively prevent the autolysis of the skin tissue's own enzymes from digesting the skin protein, and it will also generate small cod balls on the skin, causing erythema to form on the skin, and the raw skin Gelling, which seriously affects the quality of raw leather. The antiseptic effect of freezing method, radiation method and organic solvent dehydration method is better, but because most of the sources o...

Problems solved by technology

Drying method, salting method and salt drying method all exist, which cannot effectively prevent the autolysis of the skin tissue's own enzymes to digest the skin protein, and it will also produce cod microbes on the skin, causing erythema to form on the skin. Gelling, which seriously affects the quality of raw leather

The antiseptic effect of freezing method, radiation method and organic solvent dehydration method is better, but because most of the sources of raw hides are scattered slaughtering and individual processing, it has limitations, and it also has complex processes and high production costs.
