Abstract

The invention provides a synthetic leather surface conditioning agent. The synthetic leather surface conditioning agent comprises, by weight, 60-80 parts of aqueous polyurethane resin, 20-40 parts of water, 0.5-1.0 part of an aqueous wetting leveling agent, 0.5-1.0 part of an aqueous antifoaming agent, 1-2 parts of an aqueous thickening agent, 5-10 parts of aqueous matting powder, 1-5 parts of an aqueous slip agent and 5-10 parts of an aqueous wax emulsion. The aqueous polyurethane surface conditioning agent has effects of dye fixation and wear resistance on the synthetic leather surface, makes synthetic leather surface fine and smooth, does not contain VOC, does not cause resource waste and environmental pollution, satisfies safety, environmental friendliness and energy saving requirements and is conducive to human health.

Description

technical field [0001] The invention relates to the field of compositions, and specifically discloses a surface treatment agent for synthetic leather. Background technique [0002] Synthetic leather, also known as polyurethane (PU) synthetic leather, is usually produced and processed from polyurethane resin and non-woven fabrics, woven fabrics or woven fabrics. The use of PU synthetic leather to decorate sofas, bags, clothing, shoes, cars and furniture has been increasingly recognized by the market. At present, in the field of synthetic leather production, surface treatment agents mainly include printing, spraying, rolling coating and other processes, which can change the color of synthetic leather, increase matting treatment, improve the surface touch and form many different styles, because it can greatly improve the product quality. The grade and added value are more and more valued by the market. Chinese patent 201310113085.X proposes a skin-feeling polyurethane leather...
