Problems solved by technology

[0004] Traditional fatliquors are mostly composed of animal and vegetable oils and their modified products. There are many unsaturated oils, which are easily decomposed by light and heat to cause rancidity and form some volatile components. There are also many volatile components in the raw materials, so the atomization value and higher VOC

Abstract

The invention provides a low-atomization leather synthetic fatliquoring agent as well as its preparation method and application, and relates to the technical field of leather chemical industry. The synthetic fatliquoring agent for low atomization leather provided by the present invention, the preparation raw material comprises the following components by weight: 20-40 parts of N-oleoyl sarcosine; 50-100 parts of palm oil; 10-20 parts of maleic anhydride 10-50 parts of high boiling point mineral oil; 10-50 parts of synthetic oil; 5-50 parts of neutralizer; 10-30 parts of emulsifier; 100-200 parts of water. In the raw material components used in the present invention, there are less unsaturated oils and volatile components, and the higher saturation of palm oil is used to further reduce the formation of volatiles through chemical modification, and then matched with high-boiling point mineral oil, thereby reducing fog value and VOC; the low fogging leather synthetic fatliquoring agent provided by the invention is used for automobile upholstery leather, and good low fogging performance can be obtained.

Description

technical field [0001] The invention relates to the technical field of leather chemical industry, in particular to a low-atomization leather synthetic fatliquor and a preparation method and application thereof. Background technique [0002] Fatliquoring is the most critical process in tanning production. By reasonably and properly fatliquoring the raw leather, it can absorb an appropriate amount of fatliquoring material, restore its original softness and elasticity, and prevent the leather from stiffening and cracking. Gives leather a certain performance. Through fatliquoring, the tensile strength, toughness, elongation, and leather yield of the leather are improved, and the water resistance is significantly improved, and the leather is also given a good feel. [0003] With the improvement of people's living standards, cars have entered millions of households, and people's demand for high-end cars is also increasing. The interiors of high-end cars, especially car seat cushi...
