Abstract
The invention relates to a leather fatliquor, which is prepared from the following raw materials by weight: 25-36 parts of vinyl stearate, 6-8 parts of azobisisobutyronitrile, 4-7 parts of acrylic ester, 3-6 parts of carnauba wax, 4-8 parts of triethanolamine, 14-20 parts of animal oil, 8-16 parts of polyethylene glycol, 3-5 parts of formic acid, 20-35 parts of sodium alkyl sulfonate, 2-3 parts of emulsified silicone oil, 12-24 parts of 52# chlorinated paraffin, 8-12 parts of coconut diethanolamide, and 1.2-2 parts of sodium nitrite. The leather fatliquor of the present invention has effects of effective improvement of tensile strength and elongation of the formed leather, high softening effect on the leather, and reduction of the leather surface oil spots.
Description
Technical field
The present invention relates to a kind of leather fat.
Background technology
Leather greasing is an important step during leather is produced.Pass through stuffing, leather absorbs appropriate grease, each fiber is had the grease of lubrication to be surrounded, not only add fiber and the mutual mobility of fiber, leather is made to become soft folding, its tensile strength, unit elongation, water tolerance are all significantly improved, and leather fat also plays slight supplementary tanning effect, give leather with toughness.Fatting agent plays irreplaceable effect to leather, but fatting agent in the market also exists many deficiencies, such as unstable properties, and perviousness is strong, very easily makes that finished leather is hardening, embrittlement forms viscosity oil mark on leather surface, causes financial loss.
Summary of the invention
For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of leather fat, effectively improves tensile strength and the unit elongation of finished leather, large to the soft effect of leather, reduces leather surface oil mark.
For solving prior art problem, technical scheme provided by the invention is, a kind of leather fat, and it is made up of the raw material of following parts by weight:
Stearic acid vinyl ester 25-36 part, Diisopropyl azodicarboxylate 6-8 part, acrylate 4-7 part, palm wax 3-6 part, trolamine 4-8 part, animal oil 14-20 part, polyoxyethylene glycol 8-16 part, formic acid 3-5 part, alkyl sodium sulfonate 20-35 part, silicone emulsion 2-3 part, 52# clorafin 12-24 part, lauric acid amide of ethanol 8-12 part, Sodium Nitrite 1.2-2 part.
The invention has the beneficial effects as follows: leather fat of the present invention, effectively improve tensile strength and the unit elongation of finished leather, large to the soft effect of leather, reduce leather surface oil mark.
