Abstract

The invention relates to an eco-solvent cloudy surface waxy-feeling treatment agent for synthetic leather and its preparation method. The treatment agent consists of modified PU resin, acetone, xylene, silicon dioxide matting agent and modified siloxane. The treatment agent is colorless transparent liquid, has good color development property and leveling property, takes eco-solvent system, and has low corrosivity on leather surface, and leather treated by the treatment agent has good cloudy surface, natural gloss, smooth feeling, fine waxy-feeling, unique and comfortable touch feeling and perfect comprehensive effect.

Description

technical field [0001] The invention relates to a treatment agent for synthetic leather, in particular to a treatment agent for weak solvent matte wax for synthetic leather which is applied to the post-process of synthetic leather. The preparation method of wax treatment agent. Background technique [0002] Synthetic leather is a product that simulates the composition and structure of natural leather and can be used as a substitute material. Usually, the impregnated non-woven fabric is used as the mesh layer, and the microporous polyurethane layer is used as the grain layer. Its front and back are very similar to leather, and has a certain degree of air permeability, which is closer to natural leather than ordinary artificial leather. Widely used in making shoes, boots, bags and ball games. In practice, synthetic leather is usually surface-treated to obtain the effect of genuine leather with a natural luster and soft touch. [0003] The treatment agent for synthetic leat...
