Abstract

The invention provides a fish oil fatliquoring agent and a preparation method thereof. The fish oil fatliquoring agent consists of higher alcohol, maleic anhydride, fish oil, an antioxidant, mineral oil, a sulfonating agent, a composite emulsifier and a preservative. By using the fish oil fatliquoring agent, the optical activity resistance and fullness of leather can be improved so as to achieve obtain a satisfied fatliquoring effect, and the fishlike smell of the fish oil fatliquoring agent is light, thus greatly extending the use range of the fish oil fatliquoring agent. The method for preparing the fish oil fatliquoring agent is relatively simple and has no high requirement on equipment and short production period.

Description

A kind of fish-oil stuffing agent and preparation method thereof
Technical field
The present invention relates to a kind of fatting agent and preparation method thereof, more particularly, the present invention relates to a kind of fish-oil stuffing agent and preparation method thereof.
Background technology
Fatting agent is the chemical materials of consumption maximum in the tanning production, also is one of important chemical materials in the leather processing procedure.It can lubricate leather fiber, prevents that leather from stiff, cracking taking place, and can make leather have corresponding toughness and flexibility again, and keep its intensity, play certain filling effect simultaneously, make leather plentiful flexible, we can say that fatting agent is one of important factor that influences the leather quality performance.In fatting agent research, fatty alcohol phosphate, lipid acid high alcohol ester, neat's foot oil, lanolin, natural phospholipid, fish oil, synthetic macromolecule poly phosphate etc. all have good fillibility.The marine animal oil fatting agent that with fish oil is representative is the bulk product in the leather fat, the characteristics of fish oil are that degree of unsaturation is big, the iodine number height, the distribution range broad of molecular weight, so fish oil simultaneously has tangible advantage as other vegetable and animals oils of raw material ratio of leather fat.At first, reactions such as oxidation, sulfation and iodate take place in iodine number higher unsaturated acid easily, and reactive behavior is higher, easily make the higher leather greasing material of active quantities, and fish-oil stuffing agent perviousness is strong, and pliability is good, the oiliness foot, and the leather unit elongation after the stuffing is big; Secondly also have performances such as filling preferably.Handle leather with the fish-oil stuffing agent and can make leather keep the softness and the performance of moistening of many decades, this is that other fatting agent can not be compared.But, since more and more higher to the sunproof requirement of leather at present, and natural fish oil contains more unsaturated link(age), easy oxidation discoloration, and have a fish like smell, therefore limited the range of application of fish-oil stuffing agent.
Summary of the invention
The purpose of this invention is to provide a kind of fish-oil stuffing agent, to solve the above-mentioned problems in the prior art, the comprehensive stuffing performance of this fish-oil stuffing agent of the present invention is good, not only can improve the light fastness and the fullness ratio of leather with fish-oil stuffing agent of the present invention, obtain satisfied stuffing effect, and this fish-oil stuffing agent fishy smell road is light, has widened the use range of this fatting agent.
Another object of the present invention provides a kind of preparation method of above-mentioned fish-oil stuffing agent, and this preparation method is simple relatively, and not high to equipment requirements, the production cycle is shorter.
Fish-oil stuffing agent of the present invention is composed of the following components by weight percentage:
The carbon number of above-mentioned higher alcohols is 16~22
Prepare the method for fish-oil stuffing agent of the present invention, form by following steps:
(1) higher alcohols are joined in the 1# reactor, be warmed up to 50~55 ℃, stir adding MALEIC ANHYDRIDE down, be warming up to 85~95 ℃, reacted 2~3 hours, standby;
(2) fish oil is joined in the 2# reactor, add oxidation inhibitor then successively, mineral oil, 30% the sulphonating agent aqueous solution, its weight percent is: oxidation inhibitor 0.3%~0.5%, mineral oil 15%~20%, sulphonating agent 3%~5%; When temperature was raised to 45~55 ℃, adding 1# material in reactor continued to be warmed up to 85~95 ℃, stirred to mix in 1~1.5 hour;
(3) be cooled to 60~65 ℃, in said mixture, add compound emulsifying agent, sanitas;
(4) keep 60~65 ℃ of temperature, in said mixture, add neutralizing agent, regulate pH value 7~9; Slowly add a certain amount of distilled water and make oil-contg 68~72%, fully stirred 1.5~2.5 hours, promptly obtain the fish-oil stuffing agent.
