Water-based polishing treatment agent for synthetic leather and preparation method of agent

Abstract

The invention relates to a water-based polishing treatment agent for synthetic leather. The water-based polishing treatment agent is applied to the back-end process of the synthetic leather and comprises components as follows: water-based resin, a water-based dispersing agent, a defoaming agent, silica matting powder, a water-based brightener, a wetting agent, a Deuchem thickening agent and water. The invention further relates to a preparation method of the water-based polishing treatment agent for the synthetic leather. All components of the water-based polishing treatment agent coordinate with one another and have the combined action, the synthetic leather is unique in hand feeling after treatment and has the advantages of avoidance of cracking during baking at the high temperature and the like, meanwhile, a prepared spraying diluted solution has the good storage stability, a pigment does not deposit easily, and the leather treated with the treatment agent has the natural gloss, the clear color, the good color developing property and the good comprehensive effect. The water-based polishing treatment agent for the synthetic leather is a novel material for back-end treatment and can be applied to an existing synthetic leather production line, the process is simple, production equipment is not required to be changed, and the production cost cannot be increased.

Description

technical field [0001] The invention relates to the field of surface treatment agents for synthetic leather, in particular, to an aqueous polishing treatment agent for synthetic leather used in the back-end process of synthetic leather, and also relates to a preparation method of the aqueous polishing treatment agent for synthetic leather. Background technique [0002] Synthetic leather surface treatment agent can be used for surface finishing according to the product category, which can improve the brightness, color and feel of synthetic leather. However, as consumers have higher and higher requirements for the color and feel of the leather surface, it is not only necessary to increase the touch of the synthetic leather, but also to ensure the brightness and color of the synthetic leather surface. However, the existing surface treatment agents have been unable to meet consumers' increasing requirements for the brightness and feel of synthetic leather. Therefore, there is an...

However, the existing surface treatment agents can no longer meet the increasing requirements of consumers for the brightness and handle of synthetic leather. Therefore, there is an urgent need for a synthetic leather that can not only improve the touch of synthetic leather, but also improve the comprehensive effects of synthetic leather such as handle, brightness, and gloss. treatment agent
