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

preparation example Construction

[0049] The present invention also provides the preparation method of the low atomized leather synthetic fatliquoring agent described in the above technical scheme, comprising the following steps:

[0050] Mix N-oleoyl sarcosine, palm oil and a neutralizing agent to carry out a neutralization reaction to obtain a neutralized product;

[0051] Mixing the neutralized product and maleic anhydride to perform an esterification reaction to obtain an esterified product;

[0052] Physically mixing the esterified product with high-boiling mineral oil, synthetic oil, and emulsifier to obtain a mixture;

[0053] The mixture is mixed with water and emulsified to obtain a synthetic fatliquor for low-fogged leather.

[0054] The invention mixes N-oleoyl sarcosine, palm oil and a neutralizer to carry out a neutralization reaction to obtain a neutralized product. In the present invention, the method for mixing N-oleoyl sarcosine, palm oil and neutralizer comprises: first mixing N-oleoyl sarcos...

Embodiment 1

[0066] In parts by weight, 20 parts of N-oleoyl sarcosine and 50 parts of 24-degree palm oil were added to the reaction kettle, 15 parts of monoethanolamine were added dropwise, and the neutralization reaction was carried out for 1 hour to obtain a neutralized product;

[0067] The neutralized product was heated to 100°C, 10 parts of maleic anhydride was added, and the esterification reaction was carried out for 5 hours to obtain the esterified product;

Abstract

The invention provides a low-atomization leather synthetic fatting agent as well as a preparation method and application thereof, and relates to the technical field of leather chemical engineering. The invention provides a low-atomization synthetic leather fatting agent. The low-atomization synthetic leather fatting agent is prepared from the following raw materials in parts 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 mineral oil with a high boiling point; 10-50 parts of synthetic grease; 5-50 parts of a neutralizer; 10-30 parts of an emulsifier; 100-200 parts of water. Unsaturated grease and volatile components in the adopted raw material components are few, the high saturation degree of palm oil is utilized, volatile matter formation is further reduced through chemical modification, and high-boiling-point mineral oil is matched, so that the atomization value and VOC are reduced; when the low-atomization synthetic leather fatting agent provided by the invention is used for automobile base cushion leather, good low-atomization 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 fatliquoring agent and its preparation method and application. Background technique [0002] Fatliquoring is the most critical process in tanning production. Reasonable and appropriate fatliquoring is carried out on the crust leather to allow it to absorb an appropriate amount of fatliquoring materials, restore its original softness and elasticity, and prevent the leather from becoming stiff and cracking. Give the leather a certain performance. Through fatliquoring, the tensile strength, toughness, elongation, leather yield, etc. of the leather are improved, and at the same time, the water resistance is significantly improved, and the leather is also endowed with a good feel. [0003] With the improvement of people's living standards, cars have entered tens of millions of families, and people's demand for high-end cars is als...
