Description

A kind of composite synthetic fat liquor and preparation method thereof

Technical field

The present invention relates to a kind of fatting agent and preparation method thereof, it is more particularly related to a kind of composite synthetic fat liquor and preparation method thereof.

Background technology

Fatting agent is the skin material of consumption maximum in tanning production, is also one of important chemical materials in leather processing procedure.It can lubricate Leather fiber, prevent leather it is stiff, cracking, can make leather that there is corresponding toughness and flexibility again, and keep its intensity, it may be said that fatting agent It is one of key factor of influence leather quality performance.In curriery, synthetic fat liquor obtains attention and the green grass or young crops of people with its excellent stuffing effect Look at, its type and quantity is also increasing year by year, and the fatting agent of top grade is belonged to always.In higher alcohols sulfosuccinic acid ester molecular structure containing carboxyl, Sulfonic group isoreactivity group, with stronger acidproof, alkaline-resisting, salt tolerant ability, moreover it is possible to assign leather good hydrophobicity and fillibility, so as to have There are stuffing and filling effect, stuffing effect is permanent, leather is kept soft, plentiful, flexible for a long time, and possess certain mercerising sense, wax sense and moisten Feel, the position for reducing hide is poor, improves the water resistance of leather.Therefore, higher alcohols sulfosuccinate is a kind of ideal stuffing material, There is positive meaning to improving resultant leather quality.But at present, seldom, performance is single for synthetic fat liquor species, majority be all with natural oil and its Low middle-grade fatting agent based on modifier.

The content of the invention

It is an object of the invention to provide a kind of composite synthetic fat liquor, to solve the above-mentioned problems in the prior art, compound conjunction of the invention It is good into fatting agent fatliquoring function, can be with reduces cost, the performance of raising leather with composite synthetic fat liquor of the invention.

Another object of the present invention is to provide a kind of preparation method of composite synthetic fat liquor, and the method is simple, not high to equipment requirement, raw The product cycle is shorter.

Above-mentioned silicone oil is the dimethicone or amido silicon oil of 100~1000cp of viscosity.

The above-mentioned carbon number for stating higher alcohols sulfosuccinate is 12~22, and preferably the carbon number of higher alcohols sulfosuccinate is 16~20.

The method for preparing composite synthetic fat liquor of the invention is comprised the steps of：

(1) to 15%~25% sulfonation agent solution is added dropwise in higher alcohols succinate, sulfonating agent is selected from sodium sulfite, sodium pyrosulfite or amino sulphur Acid, higher alcohols succinate is 100 with sulfonating agent mass ratio：10~100：30, preferably 100：15~100：20, temperature be 70~ 100 DEG C, preferably 80~90 DEG C, react 4~10 hours, preferably 5~7 hours；

(2) above-mentioned solution is cooled to 50 DEG C, adds mineral oil, silicone oil, sulfited lanolin and the emulsifying agent, its percentage by weight to be：It is high Carbon alcohol sulfosuccinate 25%~30%, mineral oil 30%~35%, silicone oil 5%~10%, sulfited lanolin 15%~20%, Emulsifying agent 10%~13%, stirs 1~2 hour, adds alkali to be neutralized, and alkali is selected from sodium hydroxide solution, ammoniacal liquor, monoethanolamine or three Monoethanolamine, regulation pH value to 7.5~8.5；

(3) to a certain amount of water is added in above-mentioned solution, make water containing amount≤50%, add stabilizer, stabilizer be selected from isopropanol, isobutanol, Isoamyl alcohol, n-octyl alcohol, isooctanol or sec-octyl alcohol, stir 1~2 hour, that is, obtain composite synthetic fat liquor.

APEO (NPE and OPEO) of the composite synthetic fat liquor without European Union's limitation is prepared in the present invention And chlorinated paraffin, basic three-waste free discharge, belongs to environmentally friendly machine during production and use.
