Problems solved by technology

[0003] However, in the shoe-making process, the oily wax in the oily leather material is not conducive to the bonding of the oily leather and seriously affects the quality of the shoes. Therefore, the research on the effective treatment of the oily leather material has become particularly important.

Embodiment

[0021] The materials or reagents for preparing the environment-friendly high-performance oily skin treatment agent in the following examples of the present invention are all commercially available products.

[0022] The environment-friendly oily high-performance leather treatment agent is prepared through the following steps, which specifically includes the following steps in sequence:

[0023] 1) Add MEK, polyester polyol and IPDI to the reaction kettle, heat up to 80°C and stir to dissolve.

[0024] 2) Add MBT, and time the reaction for 2-2.5 hours.

[0025] 3) Add PVB, MEK, and MMA into the reaction kettle in sequence, and dissolve for 0.5-1 hour.

[0026] 4) After AIBN and CYC are dissolved, add it to the reaction kettle and react for 4-5 hours by time.

[0027] 5) Add PPG200 and EGDA in sequence, dissolve and cool down to room temperature, and then an environment-friendly oily skin treatment agent with a solid content of 30±2% is prepared. Among them, the specific addi...

Abstract

The invention discloses an environment-friendly high-performance oily leather treating agent and a preparation method thereof. The treating agent is prepared from the following components in parts by weight: 100 parts of polyester polyol, 8 to 10 parts of isophorone diisocyanate, 12 to 24 parts of polyvinyl butyral, 10 to 30 parts of methyl methacrylate, 230 to 260 parts of butanone, 0.03 to 0.05 part of organic tin, 0.4 to 1 part of azodiisobutyronitrile, 10 to 20 parts of cyclohexanone, 40 to 80 parts of polypropylene glycol and 10 to 15 parts of ethylene glycol diacetate. The oily leather treating agent is obtained by modifying polyurethane glue through a polymerization reaction, can realize adsorption of oil wax in an oily leather material, and has an excellent treatment effect on oily leather with high oil content. A bonding effect can be achieved without pre-treating oily leather. In addition, the treating agent uses a triphenyl-free environment-friendly solvent and does not contain harmful substances such as benzene, methylbenzene and xylene.

Description

technical field [0001] The invention relates to the technical field of leather treatment agents, in particular to an environment-friendly high-performance oily leather treatment agent. Background technique [0002] As we all know, oil leather belongs to the most natural high-grade leather. It is a special cowhide formed by polishing, oiling and waxing the top layer of cowhide. The leather surface is covered with a thin layer of wax, and the whole oil leather is permeated with oil. The excellent leather feeling effect makes oily leather the first choice for major world brands. [0003] However, in the shoe-making process, the oil wax in the oil leather material is not conducive to the adhesion of the oil leather and seriously affects the quality of the shoes. Therefore, the research on the effective treatment of the oil leather material has become particularly important. [0004] The existing oily skin treatment agent is effective for treating oily skin with low oil content,...
