Description
Technical field
The invention belongs to process hides sterilization and anticorrosion technical fields, and in particular to a kind of safety and environmental protection, it is biodegradable, have it is good
The raw hide compound preservative of good sterilization and anticorrosion effect.
Background technology
The raw material sources of leather industry are rich in 30% ~ 35% protein and 60% ~ 75% in natural animal skin, raw hide
Moisture, be vulnerable to the erosion of microorganism and the hydrolysis of itself enzyme in storage and transport process and rot.Leather industry
It earns foreign exchange 10,000,000,000 dollars or more for China's export every year, process hides raw material skin anti-corrosion preserves and beam house immersion operation is used as source
Technique has been largely fixed aesthetic quality and the physical property of resultant Leather.Therefore, sterilization and anticorrosion is most important.Commonly
Anti-corrosion method is broadly divided into physics, chemistry and bioanalysis three categories.By reducing intradermal moisture, changes temperature, pH value, make
At the environment for being unsuitable for bacterial growth breeding, or microorganism structure is destroyed, inhibits enzyme or protein active, directly kill bacterium, reach
To anti-corrosion purpose.
Typical Representative of the salted method of sodium chloride as chemical preservation method, will produce the salt pollution problem of high concentration.With it
His most pollutants are different, and sodium chloride dissolubility is good, and chemical property is stablized, it is difficult to effectively remove.Highly-saline waste water meeting
Seriously affect the growth of plant and aquatile.In addition, there is also Environmental Health safety wind for leather industry anti-corrosion fungicide
Danger.Currently, new environmental regulation has formulated sternly the use of chloride content in waste leather-making liquid and high toxic side effect chemicals
The policy and standard of lattice, develop new environmental type anti-corrosion material and application technology is imperative.
Polyethylene glycol（PEG）Characteristic nontoxic with its, hydrophilic is preserved for organ, sample is fixed and raw hide is smeared and prevented
It is rotten, it was demonstrated that it has anticorrosion mechanism similar with sodium chloride, has both dehydration and fungistatic effect.And quaternary ammonium salt cationic activity is killed
Microbial inoculum belongs to less toxic chemicals, to human health safety, is not included at present by EU REACH Legislation《SVHC inventories》, by broken
The cell wall and membrane structure of bad microorganism inhibit protein active, influence cell metabolism, and with its low toxicity, efficient, wide spectrum
Etc. advantages, medicine, daily chemicals field be widely used in sterilization, disinfection, anti-corrosion.It has been reported that quaternary ammonium salt is used for process hides raw hide anti-corrosion
Effectively bacterium can be inhibited to increase with immersion process, at the same it had both as a kind of cationic surfactant accelerate immersion, decontamination,
Degreasing, washing and other effects.The use of one-component fungicide can make bacterium generate resistance, therefore several kill is often used in practical application
The compound product of microbial inoculum not only considers the bactericidal property of fungicide, can also take into account the safety of chemicals, while also having economy
Reasonability.
The present invention provides a kind of salt-free or few salt-PEG/ quaternary ammonium salt composite bactericidal preservatives and preparation method thereof.This is anti-
Rotten agent is a kind of safety and environmental protection, biodegradable, the good raw hide sterilization antiseptic of bactericidal effect, and preparation method is simple, behaviour
It is strong to make feasibility, cost is reasonable, for substituting salt anti-corrosion, can effectively reduce salt dosage, can be used for process hides raw hide anti-corrosion preserve and
The sterilization and anticorrosion of wet practice process has good application prospect.
