Description
Technical field
The present invention relates to field of leather care, specifically, being the solubilized type Degreasing Agent of the resistance to jelly of one kind and its preparation side
Method.
Background technique
In leather industry, raw material is intradermal all can be with the presence of a certain amount of fat, if without ungrease treatment, it will hinder
Leather-making technology material to intracutaneous infiltration, and the fatty acid that generates of grease hydrolysis can be reacted with metal ion to be formed it is not soluble in water
Metallic soap salt, be unfavorable for dyeing processing, therefore, skimming processes are generally through the wet practice stage of entire leather-making technology.Mesh
The preceding method industrially generallyd use is emulsion degreasing method, and effective component is based on surfactant, cation surface activating
The emulsifying capacity of agent is lower, the effect of emulsified fat can be also lost in conjunction with collagen under higher pH condition, so uncomfortable
Share in degreasing agent, domestic degreasing agent often using anion and nonionic surfactant as main component, and require used in
Surfactant should have good emulsified fat ability and and permeance property, the intradermal portion of raw material can be penetrated into, it is profound
Removing fat.
Common anionic surfactant is neopelex and fatty alcohol ether sulphate, is all had good
Emulsifying ability and penetration, nonionic surfactant mostly use fatty alcohol polyoxyethylene ether AEO7, AEO9 etc., can be with anion table
Face activating agent shows synergistic function, enhances the emulsion degreasing effect of degreasing agent, but the solidification of fatty alcohol polyoxyethylene ether
Point is high, and at low temperature (10 DEG C or less), the fatty alcohol polyoxyethylene ether in degreasing agent can be precipitated and make product at white casse shape,
It needs a certain amount of solubilizer to eliminate the effects of the act, is unfavorable for the dispersion effect of degreasing agent in a liquid carrier.Fatty acid methyl ester ethoxy
Glycolylate derives from natural oil, is a kind of green nonionic surfactant emerging in recent years, and structure includes ester group, according to
According to the similar principle that mixes, fatty acid methyl ester ethoxylate has good emulsifying effectiveness, and water-soluble and permeance property to grease
It is excellent, such raw material is added in degreasing agent, still keeps flowable transparent shape at low temperature.
The Chinese patent application of Patent No. ZL201010202616.9, Publication No. CN101851690A disclose one kind
Degreasing Agent, including mass fraction be 100 aminosal type surfactant, mass fraction be 3~10 dodecane
The sodium carbonate that fatty alcohol polyoxyethylene ether that base benzene sulfonic acid sodium salt, mass fraction are 3~10, mass fraction are 3~10, wherein water
Solution protein type surfactant is to react to be made with fat acyl chloride again after using sodium hydroxide hydrolysis tanning leftover.The patent is adopted
Aminosal type surfactant emulsifies are functional, but molecular weight is big, are easily precipitated and shadow from degreasing agent under low temperature
Using effect is rung, and permeance property is general, though fatty alcohol polyoxyethylene ether, which is added, improves its permeability, its degreasing rate is only suitable
In general degreasing agent, there is also the storage under low temperature and problem is used, is not suitable for dedicated degreasing demanding to degreasing rate
Agent.
Application No. is 201410586177.4, the Chinese patent application of Publication No. CN105623922A discloses a kind of skin
Degreasing agent is removed from office, constituent is according to the mass fraction are as follows: 5~10 parts of surfactant, 4~6 parts of fatty alcohol polyoxyethylene ether, ten
Eight 1~6 part of alkyl dimethylamine oxides ammoniums, 1~3 part of potassium hydroxide, 5~10 parts of lime stone, 1~2 part of kerosene, 15~25 parts of water.
The octadecyldimethyl amine-oxides that the patent uses generate amine in nonionic under alkaline condition, are in acid condition
Cationic limits the application of the Degreasing Agent in acid condition, and the kerosene environmental pollution which uses is larger,
Recycling is also difficult, the Ca of introducing2+It is also easy to form infusible precipitate with alkali or fatty acid in the subsequent process, influences process hides effect
Fruit.
