Abstract

The invention provides a high-temperature-resistant leather finishing agent prepared from the following raw materials in parts by weight: 15-24 parts of polyether polyol, 2-8 parts of a hydrophilic chain extender, 3-7 parts of castor oil, 12-18 parts of water-soluble epoxy resin, 8-14 parts of 3-allyloxy-2-hydroxyl acrylate sodium iodate, 3-4 parts of acetic ether, 1.2-2 parts of titanium dioxide, 6-8 parts of turpentine, 3-7 parts of an inorganic pigment, 2-5 parts of perchloro-ethylene resin, 4-8 parts of dibutyl phthalate, 5-7 parts of oxidized paraffin and 0.8-1.4 parts of alkyl sodium sulfonate. The high-temperature-resistant leather finishing agent provided by the invention has the beneficial effects of being very good in high temperature resistance and chemical stability and extremely good in film forming property, ensuring that a coated film is folding-resistant and flexible and leather is exquisite in hand feeling, and not influencing the environment.

Description

technical field [0001] The invention relates to a high temperature resistant leather finishing agent. Background technique [0002] Finishing is an important process in the leather manufacturing process. After the leather is finished with a finishing agent, various appearance styles and performances can be obtained, which not only achieves economic use value, but also meets people's aesthetic needs. Leather finishing agent is a general term for a class of leather auxiliary agents used to protect and beautify leather by finishing the surface of leather. Come up to achieve higher effects and improve overall performance. However, the coating agents currently on the market not only have a serious impact on the environment, but also do not have high temperature resistance. When encountering high temperatures, they will thicken or agglomerate, resulting in customized use and abandonment, resulting in certain economic losses. Contents of the invention [0003] Aiming at the def...
