Abstract
The invention relates to a waterborne matte velour-wetting treatment agent for synthetic leather. The waterborne matte velour-wetting treatment agent is composed of the following components: waterborne polyurethane resin varnish, water, penetrant, silica extinction powder, an organosilicone levelling agent, an organosilicone defoamer and a waterborne polyurethane thickener. The invention further relates to a preparation method of the waterborne matte velour-wetting treatment agent for the synthetic leather. The waterborne matte velour-wetting 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 velour-wetting treatment agent is simple in process and dispenses with the change of production equipment and the increase of cost.
