Abstract

The invention discloses a highly hydrophobicuv (ultraviolet) leather surface treating agent which comprises raw materials in percentage by weight as follows: 5%-85% of prepolymer, 10%-60% of an activated monomer, 0.01%-30% of aphotoinitiator, 1%-6% of a binder and 0.1%-10% of a thickener. The leather surface treating agent improves the hydrophobicity, oil rub resistance and scratch resistance of leather. The invention discloses a preparation method of the highly hydrophobicuvleather surface treating agent. The method is simple, reasonable in technological design, energy-saving, environment-friendly and suitable for large-scale production and application, and equipment use is simple.

Description

technical field [0001] The invention belongs to the field of post-finishing of coatings, natural leather, artificial leather, synthetic leather and textile fabrics, and particularly relates to a UV highly hydrophobic leather surface treatment agent, and also relates to a preparation method of the UV highly hydrophobic leather surface treatment agent. Background technique [0002] Traditional leather surface treatment mainly includes the following: 1. Oil-soluble treatment agent; 2. Water-based treatment agent, usually a physical mixture of water-based PA and PU resin. The physical mixture of water-based PA and PU resins are traditional treatment agents, some of which have hydrophobic effect, and the effect is single. Contents of the invention [0003] An object of the present invention is to propose a UV highly hydrophobic leather surface treatment agent, which solves the problems of single treatment effect and poor stability of the leather surface treatment agent in the p...
