Abstract
The invention relates to a preparation method of an antibacterial and antifungal fat-liquoring agent suitable for aged leather. The preparation method comprises the following specific steps: adding lactic acid and hydrogen peroxide into soybean oil, heating and mixing to carry out modification, then carrying out titration on a modified mixture by virtue of a sodium hydroxide solution until the mixture is neutral, and drying the mixture to obtain lactated modified soybean oil; compounding the lactated modified soybean oil, span-80, 2-octyl-4-isothiazoline-3-ketone, sodium sulfite, ethanol, acetic acid and deionized water to prepare an antifungal fat-liquoring agent finally. The preparation method has the advantages of versatility, obvious effect, harmlessness and the like.
Description
Technical field
The present invention relates to a kind of preparation method of antibacterial and mouldproof fatting agent, especially a kind of preparation method who is applicable to the antibacterial and mouldproof fatting agent of aging leather.
Background technology
The main component of leather is that the reticulattion by protein fibre forms.In addition, the grease using in the course of processing of leather, carbohydrate, the compositions such as inorganic salt, these all become the good nutrition source of mould-growth.So, in use procedure after leather, be accompanied by 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 bacteria mildew-proof agent of leather, main in the production processes such as tanning stuffing of leather at present.But along with leatherware is used for a long time, antibacterial and mouldproof effect fades away.And the existing fungistat for leather finished product, for some aging leatherware, although can there be certain antibacterial effect, 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 leatherware, the antibacterial and mouldproof fatting agent that has antibacterial effect and again recover color and luster.
The present invention solves the technical scheme that its technical problem adopts: comprise the following steps:
1) first get soybean oil heating in water bath in the instrument of sealing, while stir process, the time is 3～5h, temperature is 50～70 ℃;
2) in heated and stirred soybean oil process, add lactic acid and hydrogen peroxide, in 60 minutes, divide and add for 3 times, each amount of adding is consistent;
3) after above-mentioned being disposed, add the NaOH solution of soybean oil quality 5% to be titrated to neutrality, then product drying is processed, obtain the soybean oil of lactic modified;
4) soybean oil of lactic modified and span-80,2-octyl group-4-isothiazoline-3-ketone, S-WAT, ethanol, Glacial acetic acid, deionized water are carried out composite, in 60 ℃ of water-baths, carry out stirring and emulsifying, obtain a kind of antibacterial and mouldproof fatting agent that is applicable to aging leather.
Described lactic acid is 20% of soybean oil quality, and hydrogen peroxide is 60% of soybean oil quality.
In weight part, the proportioning in step 4) is composed of the following components: 30～50 parts of lactic modified soybean oil, 3～5 parts of span-80,1～3 part of 2-octyl group-4-isothiazoline-3-ketone, 1～3 part of S-WAT, 10～30 parts of ethanol, 10～20 parts, Glacial acetic acid, 80～100 parts of deionized waters.
The effect that the present invention is useful is: one, multifunctionality, when making aging leather again recover the performances such as gloss, has increased the germ resistance of leatherware; Two, successful, is applied to aging leatherware, make it recover excellent handle, and germ resistance is strong; Three, low toxicity innocuousness, formula low toxicity used, environmental protection, almost have no side effect to leatherware, can not cause secondary to damage.
