Abstract

The invention discloses a leather surface treatment agent and a preparation method thereof and relates to the technical field of leathers. The leather surface treatment agent is made mainly from waterborne polyurethane, polyethylene wax emulsion, acrylic resin, sodium benzoate, polyester diol, ethyl acetate, potassium hydroxide, isophorone diisocyanate, silica powder, waterborne polyether modified silicone oil, rice hull ash, bovine hoof oil, refined castor oil, dimethylbenzene, and a preservative aid. The leather surface treating agent imparts improved breathability to leather so that the leather is better in delicacy and smoothness, improving wear resistance of the leather and prolonging service life of the leather, and the use of the preservative aid helps improve anticorrosion performance of the leather; in addition, the addition of materials such as carbolic acid in the preservative, good sterilizing action is provided, and leather quality can be ensured.

Description

Technical field [0001] The invention relates to the technical field of leather, and more specifically to a leather surface treatment agent and a preparation method thereof. Background technique [0002] Surface treatment agent refers to the reagent used to treat the surface of a material to achieve a specific purpose. The surface treatment of leather mainly includes printing, spraying, rolling, embossing and other process methods, which can modify the color of synthetic leather, increase matting, improve the touch and form many different styles. In order to obtain high-quality leather and meet the ever-changing fashion pursuits of consumers, surface treatment agents are critical and indispensable. However, the leather surface treatment agent currently on the market is in an undesirable state, and it is necessary to further improve the technology to meet the market demand. Summary of the invention [0003] The purpose of the present invention is to make up for the deficiencies of...
