Description
Technical field
The present invention relates to a kind of preparation method of palm oil synthetic fat liquor, belongs to leather chemical industry technical field.
Background technology
Palm oil is a kind of tropical xylophyta oil, is that at present in the world output, consumption figure and the quantum of international trade are maximum
Vegetable oil kind, with soybean oil, rapeseed oil and be referred to as " the big vegetable oil in the world three ", have more than the edible history of 5,000 years.
Carry through refining point, the product of different melting points can be obtained, possess extensively in catering trade, food industry and oil and fat chemical industry respectively
Purposes.The strong oil feel of palm oil, resistance to oxidation, color inhibition, and cheap, the fatting agent raw material vegetable seed commonly used with leather industry
Oil phase ratio, its price only has 45-55% of rapeseed oil or so, should be that the one kind used as leather fat raw material is preferably selected
Select.But because palm oil contains 50% saturated fat, it is referred to as saturation grease, its freezing point is very high, even if best palm
Oil, fusing point all at 20 DEG C or so, in-convenience in use, and as during fatting agent raw material because iodine number is low, it is not easy to it is modified.Tradition
Method of modifying be take to rapeseed oil be similar to method of modifying, first access monoethanolamine, then with maleic acid anhydride reactant after, then
Plus sulphite carries out sulfonation, off-white color creamy product is obtained.This method of modifying has cut off aliphatic chain, reduces grease itself
Oil sense, finished leather is dry after stuffing, it is glossy sense it is poor, and due to palm oil saturation degree height, it is still creamy product to obtain product, is made
With inconvenience, although therefore palm oil has many merits, be widely used in other field, leather fat has been rarely used for
In.
Palm oil iodine number is low, and saturation degree is high, is difficult to realize the method for modifying of oxidate and sulfite, and neat's foot oil iodine number compared with
Height, the neat's foot oil Jing after ethoxyquin possesses self-emulsifying effect, and palm oil is when aoxidizing together, can to have graft reaction with it,
Improve molecular weight.This is used cooperatively Jing, and sulfiting requirement can be met after oxidation, and grease freezing point is more original after sulfiting
It is greatly reduced, can so uses also easily to less than 0 DEG C, and because molecular weight is big, the glossy sense of stuffing is strong, can give
The plentiful effect of leather.
The content of the invention
The purpose of the present invention is the deficiency for palm oil and its modified fat-liquoring agent product, there is provided a kind of palm oil synthesis adds
The preparation method of fat agent.The present invention carries out oxidate and sulfite and is modified using ethoxyquin neat's foot oil cooperation palm oil, finally can obtain
To the palm oil synthetic fat liquor product of rufous oily liquids.Advantages of the present invention has：Low price, can replace process hides to commonly use
Sulfonated oil；Oil sense modified compared to traditional palm oil fatting agent is poor, and solidification inconvenience is used, and method of modifying of the present invention does not affect
The characteristics of palm oil strong oil feel, and finished product be oily liquids, convenient use.The palm oil synthesis stuffing provided using the present invention
Agent carries out stuffing, and comprehensive fatliquoring function is good, and finished leather has good glossy sense and richness.
The present invention realizes that the technical scheme that foregoing invention purpose is adopted is：
A kind of preparation method of palm oil synthetic fat liquor.Specifically include following steps：
（1）In parts by weight, ethoxyquin neat's foot oil 25-40 parts, palm oil 60-75 parts, 0.1 part of catalyst is added to heat up

（2）Maleic anhydride 5-8 parts are added, 85-95 DEG C of reaction 3-4 hour is warming up to；
（3）40 DEG C are cooled to, add 2.4 parts of NaOH to be dissolved in the aqueous solution of 5.6 parts of water, system pH is neutralized to into 6-
7；
（4）Add 10 parts of sodium pyrosulfite to be dissolved in the aqueous solution of 15 parts of water, be warming up to 75-80 DEG C, react 4-5 hours, drop
Temperature adds water adjustment percetage by weight solid content 75% or so to 40 DEG C, stirs 1 hour, obtains final product the palm oil synthesis stuffing
Agent, outward appearance is rufous transparent oily liquid.
In above-mentioned preparation method, described ethoxyquin neat's foot oil is the ethoxy that ethyleneoxide addition molal quantity is 10-40mol
Change neat's foot oil.
