Abstract
The invention provides a natural phospholipid compound greasing agent and a preparation method thereof. The natural phospholipid compound greasing agent consists of natural phospholipid, sulfitation neat's foot oil and fatty alcohol phosphate. The natural phospholipid compound greasing agent for greasing can improve the waterproof performance and fullness of leather and achieve satisfying greasing effect; and the natural phospholipid compound greasing agent is suitable for greasing light color leather due to light color. The method for preparing the natural phospholipid compound greasing agent comprises the following steps of: (1) heating natural phospholipid to between 50 and 70 DEG C, adding a compound decolorizing agent into the natural phospholipid, fully reacting the mixture for 3 to 4 hours, and then adding the following components in percentage by weight into the mixture: 7 to 10 percent of compound emulsifying agent, 7.5 to 10 percent of sulfitation neat's foot oil and 7.5 to 10 percent of fatty alcohol phosphate; keeping the temperature between 50 and 70 DEG C, stirring the components for 1 hour and mixing the components uniformly; (2) adding 30 percent sodium hydroxide solution into the grease mixture to perform neutralization, and adjusting the pH value to between 6.0 and 8.0; and (3) slowly adding a certain amount of distilled water (preheated to 80 DEG C) into the mixture to keep the oil content between 48 and 52 percent, and fully stirring the mixture for 2 to 5 hours to obtain the modified phospholipid compound greasing agent. The method is relatively simple, has low demand to the apparatus and has short production phase.
Description
Technical field
The present invention relates to a kind of fat liquoring complex agent and preparation method thereof, more particularly, the present invention relates to a kind of natural phospholipid compound greasing agent composition and method of making the same.
Background technology
Fatting agent is the chemical materials of consumption maximum in tanning production, is also one of important chemical materials in leather processing procedure.It can lubricate leather fiber, prevents that leather from stiff, cracking occurring, and can make again leather have corresponding toughness and flexibility, and keep its intensity, play certain filling effect simultaneously, make leather plentiful flexible, can say that fatting agent is one of important factor affecting leather quality performance.In fatting agent research, fatty alcohol phosphate, lipid acid high alcohol ester, neat's foot oil, lanolin, natural phospholipid, synthetic macromolecule poly phosphate etc. all have good fillibility.Wherein phosphatide fatting agent obtains people's attention and favor with its good stuffing filling effect and cheap price, and its kind and quantity, also at increasing year by year, are the fatting agents of a class top grade.In this class fatting agent molecular structure, contain phosphate radical isoreactivity group, there is the ability of stronger acidproof, alkaline-resisting, salt tolerant, can enter in leather and remove from office the amino effect in fiber, with Protein formation complex body, thereby there is stuffing and filling effect, simultaneously can also with leather in chromium have very strong complexing, leather is produced to permanent stuffing effect, make to remove from office permanent maintenance soft, plentiful, flexible, the position that dwindles hide is poor, improve the water resistance of leather, and possess certain mercerising sense, wax sense and moist feel.Therefore, phosphatide fatting agent is a kind of comparatively desirable stuffing material, has positive meaning to improving resultant leather quality.But natural phospholipid color and luster is darker, be unfit to do shallow leather and remove from office in vain fatting agent, and HLB value is low, wetting ability is poor, and directly use cannot reach stuffing requirement, is easily attached to leather surface, pollutes.
Summary of the invention
The object of this invention is to provide a kind of natural phospholipid compound greasing agent, to solve the above-mentioned problems in the prior art, the comprehensive stuffing performance of this natural phospholipid compound greasing agent of the present invention is good, not only can improve water resistance and the fullness ratio of leather with this natural phospholipid compound greasing agent of the present invention, obtain satisfied stuffing effect, and this natural phospholipid compound greasing agent lighter color, be suitable for the stuffing of light color leather.
Another object of the present invention is to provide a kind of preparation method of above-mentioned natural phospholipid compound greasing agent, and this preparation method is relatively simple, and not high to equipment requirements, the production cycle is shorter.
Natural phospholipid compound greasing agent of the present invention is composed of the following components by weight percentage:
Natural phospholipid 30%～35%
Composite decoloring agent 0.2%～0.4%
Compound emulsifying agent 7%～10%
Sulphiting neat's foot oil 7.5%～10%
Fatty alcohol phosphate 7.5%～10%
Distilled water 48%～52%
The carbon number of above-mentioned fatty alcohol phosphate is 12～22, and the carbon number of preferred fat alcohol phosphoric acid ester is 16～20.
The method of preparing natural phospholipid compound greasing agent of the present invention, is made up of following steps:
(1) natural phospholipid is warming up to 50～70 DEG C, add composite decoloring agent, fully reaction 3-4 hour, then add successively compound emulsifying agent, sulphiting neat's foot oil, fatty alcohol phosphate, its weight percent is: compound emulsifying agent 7%～10%, sulphiting neat's foot oil 7.5%～10%, fatty alcohol phosphate 7.5%～10%; Keep 50～70 DEG C of temperature, stir and mix for 1 hour;
(2) in above-mentioned rich mixture, add 30% sodium hydroxide solution neutralization, regulate pH value to 6.0～8.0;
(3) in said mixture, slowly add a certain amount of distilled water (being preheated to 80 DEG C), make oil-contg 48～52%; Fully stir 2～5 hours, obtain modified phospholipid composite fat liquor.
In above-mentioned natural phospholipid, add preferably 60～65 DEG C of maintenance temperature after compound emulsifying agent, sulphiting neat's foot oil, fatty alcohol phosphate.
Churning time preferably 3～3.5 hours after above-mentioned adding distil water.
