Abstract
The invention discloses an environment-friendly raw skin preservative and a preparation method thereof. The preservative comprises the following component raw materials in percentage by weight: 42-61% of sodium chloride, 16-27% of polyvinyl alcohol, 16-27% of polyethylene glycol, 0.5-5% of polypropylene glycol, 0.5-5% of polytetrahydrofuran ether glycol and 0.5-2% of polyacrylamide, and the sum of weight percentages is 100%, wherein the molecular weight of polyvinyl alcohol is 25000-35000, the molecular weight of polyethylene glycol is 1000-10000, the molecular weight of polypropylene glycol is 400-2000, and the molecular weight of polytetrahydrofuran ether glycol is 600-2000. The preservative provided by the invention has small usage amount, is safe and nontoxic and can be biologically degraded, the total dissolved solids (TDS) and chloride pollution in tanning waste water can be greatly lowered, and no negative effect is produced on following tanning process.
Description
Technical field
The invention belongs to the leather preservative technical field, be specifically related to a kind of novel asepsis environment-protecting, biodegradable, few salt raw hide sanitas with good preservative effect.
Background technology
In process hides, rawhide can just put into production behind storage and transport after a while usually.Contain 60%～70% moisture and 25%～30% protein in the raw hide, for bacterium provides good growth and breeding environment.As not taking anti-corrosion measure, raw hide will rot because of the effect of bacterium erosion and himself " autolytic enzyme " in the preservation process.In the soaking of hide or skin process, when temperature was higher, a large amount of bacteriums is breeding and erosion raw hide fast especially, and the lighter influences resultant leather quality, and the serious skin that will make rots, thereby causes enormous economic loss.Therefore, anticorrosion is requisite operation in the process hides.
The anticorrosion of raw material skin generally is to handle with reduction intracutaneous moisture content, temperature, pH value through physics or chemical process, thereby inside and outside rawhide, causes a kind of environment that is not suitable for the bacterial growth breeding, to reach the rot-resistant purpose.Anti-corrosion method commonly used has salted method, desiccating method, cryopreservation method and pickling method, and its medium salting method is easy and simple to handle owing to having, process stabilizing, with low cost and preservative effect outstanding feature are widely used in tanning industry.But the leather-making mud that contains neutral salt (like sodium-chlor) that is produced and the improvement of waste water are the huge difficult problems that tanning industry is faced always, and the waste water of rough purification are used for irrigating farm crop in the past and can have a strong impact on the homergy of crop normal growth, the animal of upsetting environment and mikrobe and cause the secondary salinization of soil.In the last few years; Raising along with people's environmental consciousness; The appearance of more and more stricter National Environment Policy Act rule, and contain the leather-making mud of neutral salt with the emission problem of waste water receives much concern, develop a kind of salt-free/salt and cheap sanitas are imperative less.
More existing in recent years relevant leather preservative patents are open, disclose a kind of multifunctional anticorrosive agent like CN101157957A, and it is made up of sodium-chlor, yellow soda ash, sulphite, Sodium Silicofluoride 98min, refined naphthalene and Trichlorphon.Also reported some sanitass in the document, mainly contained Sodium Pyrosulfite, silicate, boric acid, Benzalkonium Chloride 80(BKC80) etc., these Chemical Preservatives are the same with salt, have dehydration and antibacterial two kinds of functions simultaneously, and preservative effect is preferably arranged.But they all have toxicity in various degree basically, do not meet the demand of public's environmental protection and safety.
Z 150PH (PVA), polyoxyethylene glycol (PEG), W 166 (PPG), PTMG (PTMG) and SEPIGEL 305 (PAM) all are nontoxic, biodegradable high molecular polymers; Its end is a hydroxyl all, has good wetting ability.Polymkeric substance that these wetting abilities are good and protein are done the time spent and can be produced very high osmotic pressure, thereby make a large amount of rapidly dehydrations of protein; In addition, can also form resist, stop the surface adsorption invasion of bacterium and the degraded of enzyme, reach the bacteriostatic effect at protein surface.Zhang Guangzhao etc. are that main raw material has prepared a series of marine antifoulants efficiently with the polyoxyethylene glycol based on this mechanism, and this product can effectively prevent absorption alow such as marine microbe, bacterium, marine alga.And also do not see patent and bibliographical information in the research of protein corrosion-resistant field about polymkeric substance such as PVA.
The invention provides a kind of environment-friendly type raw hide sanitas and preparation method thereof.This sanitas is the biodegradable few salt raw hide sanitas of a kind of safety non-toxic, have good preservative effect, and the preparation method is simple, and profit margin is big.This sanitas mainly can be used for rawhide anticorrosion in the anticorrosion and immersion workshop section of process hides, and market capacity is big, has good application prospects.
Summary of the invention
The invention provides raw hide sanitas of a kind of environmental protection and preparation method thereof.It is raw material that this sanitas mainly adopts the biodegradable polymkeric substance of safety non-toxic, when reaching the preservative effect that needs, has not only avoided the toxicity of general Chemical Preservative, and can effectively reduce high TDS and muriate pollution in the salted method.The present invention realizes that through following technical scheme except that specifying, related umber is parts by weight, and per-cent is weight percentage.
To achieve these goals; The present invention adopts following technical scheme to realize: the preparation method of this sanitas is for take by weighing a certain amount of sodium-chlor, Z 150PH, polyoxyethylene glycol, W 166, PTMG, SEPIGEL 305 respectively in proportion; Mix and be ground into powder then, promptly get environment-friendly type raw hide sanitas.Wherein, The weight percentage of each component consists of sodium-chlor 42～61%, Z 150PH 16～27%, polyoxyethylene glycol 16～27%, W 166 0.5～5%, PTMG 0.5～5%, SEPIGEL 305 0.5～2%, and it is 100% that above-mentioned each percentage ratio is formed the weight sum.
The molecular weight of Z 150PH is 25000～35000 among the above-mentioned described preparation method, and the molecular weight of polyoxyethylene glycol is 1000～10000, and the molecular weight of W 166 is 400～2000, and the molecular weight of PTMG is 600～2000.
Sanitas according to the invention can be used for the anticorrosion of the anticorrosion and immersion workshop section rawhide of process hides, and the consumption of sanitas is that 8% of rawhide～12% o'clock can reach preservative effect preferably.
Compared with present technology, adopt the sanitas of the present invention's preparation to have the following advantages:
(1) adopt the biodegradable hydrophilic high molecular polymer of safety non-toxic, have to pollute and lack, cost is low, the characteristics of favorable anti-corrosion effect, and it is anticorrosion to use it for raw hide, has expanded the new visual field of leather-making technology;
(2) hydrophilic polymer/sodium-chlor is a kind of few salt sanitas, has not only avoided the toxicity of general Chemical Preservative, and can effectively reduce high TDS and muriate pollution in the salted method, can effectively realize cleaning of the anticorrosion workshop section of rawhide in the process hides;
(3) use of the few salt sanitas of hydrophilic polymer/sodium-chlor need not introduced new tanning equipment, under original leather-making technology and facility, can use, and can not influence the over-all properties of finished leather yet.
