Description

A kind of solubilized type Degreasing Agent of resistance to jelly and preparation method thereof
Technical field
It is a kind of solubilized type Degreasing Agent of resistance to jelly and its preparation side specifically the present invention relates to field of leather care Method.
Background technology
In leather industry, raw material is intracutaneous all can be with the presence of a certain amount of fat, if without ungrease treatment, it will hinder Leather-making technology material can react to form water insoluble to intracutaneous infiltration, and the aliphatic acid of grease hydrolysis generation with metal ion Metallic soap salt, be unfavorable for dyeing processing, therefore, skimming processes are typically through the wet practice stage of whole leather-making technology.Mesh The preceding industrial method generally used is emulsion degreasing method, and its active ingredient is based on surfactant, cation surface activating The emulsifying capacity of agent is relatively low, can also be combined and lost the effect of emulsified fat with collagen under higher pH condition, so uncomfortable Share in degreasing agent, domestic degreasing agent requires used often using anion and nonionic surfactant as main component Surfactant should have good emulsified fat ability and and permeance property, the intracutaneous portion of raw material can be penetrated into, it is profound Removing fat.
Conventional anion surfactant is neopelex and fatty alcohol ether sulphate, all with good Emulsifying ability and penetration, can be with anion table using AEO AEO7, AEO9 etc. more than nonionic surfactant Face activating agent shows synergistic function, strengthens the emulsion degreasing effect of degreasing agent, but the solidification of AEO Point is high, and at low temperature (less than 10 DEG C), the AEO in degreasing agent can separate out and make product into white casse shape, Need a certain amount of solubilizer to eliminate the effects of the act, be 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 its 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, flowable transparent shape is still kept at low temperature.
Patent No. ZL201010202616.9, Publication No. CN101851690A Chinese patent application discloses one kind Degreasing Agent, including mass fraction be 100 aminosal type surfactant, mass fraction be 3~10 dodecane The sodium carbonate that AEO 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 use to be made with fat acyl chloride reaction again after sodium hydroxide hydrolysis tanning leftover.The patent is adopted Aminosal type surfactant emulsifies are functional, but molecular weight is big, easily separated out and shadow from degreasing agent under low temperature Using effect is rung, and permeance property is general, though adding AEO 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, be not suitable for the special degreasing high to degreasing rate requirement Agent.
Application No. 201410586177.4, Publication No. CN105623922A Chinese patent application discloses a kind of skin Degreasing agent is removed from office, its constituent is according to the mass fraction：5~10 parts of surfactant, 4~6 parts of AEO, 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 is used generate amine and in nonionic, are in acid condition in the basic conditions Cationic, limits the application of the Degreasing Agent in acid condition, and the kerosene environmental pollution that the patent is used is larger, Reclaim also difficult, the Ca of introducing2+Infusible precipitate, influence process hides effect are also easily formed with alkali or aliphatic acid in subsequent technique Really.
