Abstract

The invention discloses a leather greasing agent, which is prepared from the following raw materials in parts by weight: 7 to 11 parts of methacrylic acid, 6 to 8 parts of acrylic ester, 3 to 6 parts of maleic anhydride, 0.2 to 1 part of fragrance, 5 to 9 parts of triethanolamine, 4 to 8 parts of sodium metasilicate, 2 to 7 parts of polyethylene wax, 1 to 5 parts of carnauba wax, 2 to 6 parts of triglyceride, 1 to 3 parts of an emulsifier, 1 to 4 parts of ethanol, 6 to 8 parts of acrylic acid, 4 to 7 parts of polyethylene wax and 2 to 4 parts of silicon powder. The leather greasing agent has the benefits that the mechanical performance and corrosion resistance of leather can be remarkably improved, the leather greasing agent can act for a long time, the leather can be protected for a long time, and the care cost is reduced.

Description

A kind of leather fat

Technical field

The present invention relates to a kind of leather fat.

Background technology

Leather greasing is one of important procedure in leather production process, is with fatting agent process leather, makes leather absorb a certain amount of grease and give the certain physics of leather, mechanical property and use properties.Stuffing can make each fiber of leather inside be wrapped up or affine " oiliness " molecule in a large number of fiber surface by the grease with lubrication by chemistry and physical action, balance leather fiber surface energy, original high energy surface is made to change low-energy surface into, increase interfibrous mutual mobility, thus prevent leather from hardening, jackknifing, make again leather have the good physical and mechanical property such as corresponding elasticity, toughness, extensibility and flexibility.But existing fatting agent action time is short, while is acidproof and corrosive nature is poor, can not meet service requirements.

Summary of the invention

For the deficiencies in the prior art, the technical problem to be solved in the present invention is, provides a kind of leather fat, obviously can improve mechanical property and the corrosion resistance nature of leather, simultaneously long action time, can long-effective protection leather, decreases maintenance cost.

For solving the deficiencies in the prior art, the technical scheme that the present invention takes is: a kind of leather fat, is made up of the raw material of following parts by weight:

Methacrylic acid 7-11 part, acrylate 6-8 part, maleic anhydride 3-6 part, essence 0.2-1 part, trolamine 5-9 part, Starso 4-8 part, polyethylene wax 2-7 part, palm wax 1-5 part, triglyceride level 2-6 part, emulsifying agent 1-3 part, ethanol 1-4 part, vinylformic acid 6-8 part, polyethylene wax 4-7 part, silica flour 2-4 part.

The invention has the beneficial effects as follows, leather fat of the present invention, obviously can improve mechanical property and the corrosion resistance nature of leather, simultaneously long action time, can long-effective protection leather, decrease maintenance cost.
