Waterborne matte polishing treatment agent for synthetic leather and preparation method thereof

Abstract

The invention relates to a waterborne matte polishing treatment agent for synthetic leather. The waterborne matte polishing treatment agent is composed of the following components: waterborne polyurethane resin varnish, modified polyurethane emulsion, water, silica extinction powder, methoxy silicone oil, penetrant, an organosilicone levelling agent, an organosilicone defoamer and a waterborne polyurethane thickener. The invention further relates to a preparation method of the waterborne matte polishing treatment agent for the synthetic leather. The waterborne matte polishing treatment agent for the synthetic leather has a good hand feel and a good comprehensive treatment effect and is environment-friendly; and the preparation method of the waterborne matte polishing treatment agent is simple in process and dispenses with the change of production equipment and the increase of cost.

Description

technical field [0001] The invention relates to a surface treatment agent for synthetic leather, in particular to a water-based matte surface polishing treatment agent for synthetic leather applied to the front-end process of synthetic leather, and also relates to the preparation of the water-based matte surface polishing treatment agent for synthetic leather method. Background technique [0002] The emergence of synthetic leather makes up for the lack of genuine leather resources, and compared with genuine leather, synthetic leather can meet people's requirements for various styles of surfaces. In the field of synthetic leather, there are a variety of surface treatment technologies to form different surface styles, such as matte effect. It is a common method to make synthetic leather have a handle similar to genuine leather. However, the existing matte polishing treatment agents for synthetic leather are mostly Solvent-based, which has the following disadvantages: the orga...

In the field of synthetic leather, there are a variety of surface treatment technologies to form different surface styles, such as matte effect. It is a common method to make synthetic leather have a handle similar to genuine leather. However, the existing matte polishing treatment agents for synthetic leather are mostly Solvent-based, which has the following disadvantages: the organic solvent in the solvent-based surface treatment agent will cause the bottom layer of synthetic leather or artificial leather to dissolve, and the treated synthetic leather has a bad feel; The pollution is serious, and there are safety hazards such as flammability and explosion; the overall effect of treating synthetic leather is not good
