Problems solved by technology

[0002] Leather is widely used in our daily life. It can be used to make leather shoes, leather clothes, leather bags and other leather products. Leather fabrics have unique and irreplaceable advantages. Contaminated with dust, oil and other reasons, the leather surface is easy to appear dull, which seriously affects its appearance, use effect and service life. Natural leather has excellent moisture absorption and breathability characteristics. In order to maintain this natural Characteristics, when finishing and finishing, the amount of coating is generally low or not coated. Because the hydrophilicity of leather is good, its water resistance and oil resistance are generally poor. It is very difficult for consumers to deal with various oils such as engine oil, salad oil, cooking oil, etc. They have to send them to leather care shops for cleaning, which is time-consuming and labor-intensive. Most of the leather care products currently used are leather maintenance oils, although they have certain water resistance. However, the water and oil resistance is not good, and most of the leather surface treatment agents are water-based or oil-in-water, and the water and oil resistance is not strong.

Abstract

The invention discloses a nanoscale water-resisting oil-stain-resisting leather surface treatment agent and a preparing method thereof. The surface treatment agent comprises 2.0-4.0 parts of surface active agents, 28.0-50.0 parts of hydrogenated kerosene, 1.0-5.0 parts of synthetic wax, 5.0-8.0 parts of fluorine alkyl acrylate resin, 1.0-6.0 parts of active silicon oil, 0.1-0.5 part of essence, 4.0-12.0 parts of auxiliaries, 0.1-0.3 part of corrosion remover and 16.4-56.6 parts of water, wherein the surface active agents are water-in-oil type emulsifier. The preparing method includes the following steps that the surface active agents, the hydrogenated kerosene, the active silicon oil, the synthetic wax and the fluorine alkyl acrylate resin serve as the oil phase and are added into an emulsifying pot to be heated according to the ratio; water and glycerinum are added into a water phase pot to be heated, water phase drops are added into the emulsifying pot while stirring is conducted, and the mixture is evenly stirred and cooled; the corrosion remover and the essence are added to the mixture and evenly stirred. Water-in-oil type emulsifier transparent microemulsion is made through a special formula and process, the water-resisting performance and oil-stain-resisting performance are better, leather drape and tiny cracks can be effectively filled, and the mirror surface result of leather is kept.
