The preparation method provided by the invention has the advantages of multiple functions, remarkable effect, harmlessness and the like.
Description
Technical field
The present invention relates to a kind of preparation method of the antibacterial agent that eases back, especially a kind of antibacterial agent preparation method that eases back for aging stiff leather.
Background technology
Leather is as a kind of converted products of collagen matter, and the compositions such as the grease using in the course of processing, carbohydrate, are the good nutrition sources of mould-growth.So, leather use and preservation process in, along with the loss of grease, on the one hand, there is aging stiff phenomenon in leather, on the other hand, leatherware very easily produces mildew, serious outward appearance and the use properties that must affect leatherware, in addition, for the leatherware of some contact human body skins, mildew also has damaging effect to human body.
About the fungistat of leather, be mainly used in the production processes such as tanning stuffing of leather at present.But in the permanent use procedure of leatherware, fungistatic effect reduces gradually, for good and all mildew-resistant.And the existing fungistat for leather finished product, just only for germ resistance, for some aging stiff leatherware, only antibacterially can not make it recover original feel, color and luster and other performances.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, and object is to prepare a kind of for aging stiff leatherware, has fungistatic effect and the antibacterial agent that eases back of the effect that eases back.
The present invention solves the technical scheme that its technical problem adopts: comprise the following steps:
1) lanolin is carried out in encloses container to heating in water bath limit, limit stir process, the time is 1.5～3.5h, and temperature is 50～70 ℃;
2) in lanolin heated and stirred process, add gradually Vanadium Pentoxide in FLAKES powder, addition manner is minute 3 batches of interpolations in the front 30min of lanolin heated and stirred, and each Vanadium Pentoxide in FLAKES addition is identical, and the interpolation timed interval is 10min;
3), after above-mentioned heated and stirred end of processing, the sodium hydroxide solution titration mixing liquid that is 30% with massfraction, to neutral, carries out vacuum-drying to mixing liquid afterwards, obtains phosphorylation modified wool fat;
4) by carrying out compositely with tween-80,2-octyl group-4-isothiazoline-3-ketone, tea saponin, ethanol, deionized water on above-mentioned phosphorylation modified wool fat, in 50 ℃ of water-baths, carry out stirring and emulsifying, obtain the antibacterial agent that eases back.
Described Vanadium Pentoxide in FLAKES, its consumption is 3～5% of lanolin quality.
In described step 4), its each composition quality content is: phosphorylation modified wool fat 30～50%, and tween-80 3～5%, 2-octyl group-4-isothiazoline-3-ketone 0.01-0.03%, tea saponin 0.5%, ethanol 10～20%, remains as deionized water.
The effect that the present invention is useful is: one, multifunctionality, when aging stiff leather is eased back, has increased the germ resistance of leatherware; Two, successful, is applied to aging stiff leatherware, make it recover excellent handle, and germ resistance is strong; Three, innocuousness, formula low toxicity used, environmental protection, almost have no side effect to leatherware, can not cause secondary to damage.
