Abstract

The invention discloses a waterborne anti-sticking agent applicable to synthetic leather and relates to the technical field of synthetic leather functional auxiliaries. The waterborne anti-sticking agent is prepared by, by weight, 15-20 parts of oxidized polyethylene wax-hydrolytic polymaleic anhydride grafted copolymer, 5-10 parts of water-soluble modified crospovidone, 3-5 parts of volcanic ash, 3-5 parts of croscarmellose, 2-3 parts of ultrafine ceramic powder, 2-3 parts of carnauba wax, 1-2 parts of asbestos powder, 0.5-1 part of polyaluminum chloride, 0.5-1 part of nano titanium dioxide, 0.2-0.3 part of molecular sieve raw powder, 0.05-0.1 part of yttrium oxide and 150-200 parts of water. The waterborne anti-sticking agent has the advantages that the waterborne anti-sticking agent is added into a soaking box for post-processing the synthetic leather, sticking of the synthetic leather during rolling drying and subsequent grain kneading after soaking is prevented, the surface quality of the synthetic leather after the grain kneading is increased, and surface damage of the synthetic leather is avoided.

Description

[0001] Technical field: [0002] The invention relates to the technical field of synthetic leather functional assistants, in particular to an aqueous anti-sticking agent suitable for synthetic leather. [0003] Background technique: [0004] Synthetic leather, a plastic product that simulates the composition and structure of natural leather and can be used as its substitute material. Usually, the impregnated non-woven fabric is used as the mesh layer and the microporous polyurethane layer is used as the granular surface layer. The front and back sides are very similar to leather, and have a certain degree of air permeability, which is closer to natural leather than ordinary artificial leather, and are widely used in the production of shoes, boots, bags and balls. [0005] In the process of synthetic leather processing, functional additives need to be added to enhance the feel, appearance and use quality of synthetic leather products. When the synthetic leather is post-processed and k...
