Embodiment Construction

[0011] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0012] The invention provides a technical solution: a water-based auxiliary agent used in synthetic leather, which is composed of the following raw materials: ethylene glycol, propylene glycol, nano-ceramic rubber powder, oxidized polyethylene wax-hydrolyzed polymaleic anhydride graft copolymer, Beeswax, Zinc Oxide, Water, Croscarmellose Sodium.

[0013] Add inorganic acid to the propylene glycol fermentation broth, replace the organic acid salt in the fermentation broth with organic acid, and generate the corresponding inorganic acid salt at the same time, concentrate the fermentation broth, so that the inorganic acid salt crystallizes, thereby separating from the fermentation broth and concentrating The fermented liquid becomes a mixture of prop...

Abstract

The invention provides a water-based additive for synthesis leather. The water-based additive for synthesis leather is composed of ethylene glycol, propylene glycol, nanometer ceramic adhesive powder, an oxidized polyethlene wax-hydrolytic polymaleic anhydride grafted copolymer, beewax, zinc oxide, water and croscarmellose sodium. Compared with the prior art, the water-based additive has the advantages that the adhesion phenomenon in the roll drying or pattern kneading process of the synthesis leather can be prevented, the waterproofness and breathability of the synthesis leather are improved, the performance of the synthesis leather on other aspects is not affected, and other performance of the synthesis leather is kept not affected.

Description

technical field [0001] The invention relates to a water-based additive used in synthetic leather, and belongs to the technical field of functional additives for synthetic leather. Background technique [0002] Synthetic leather is 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 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. It is widely used in making shoes, boots, bags and ball games. [0003] During the processing of synthetic leather, functional auxiliary agents need to be added to enhance the hand feeling, appearance quality and use quality of synthetic leather products, but the auxiliary agents in the prior art have single functions.
