Abstract

The invention provides a high tensile strength water-based surface treatment agent for automobile leather and a preparation method thereof. The surface treatment agent comprises the following components by weight: 90-110 parts of waterborne polyurethane, 0.01-0.06 part of graphene, 2-8 parts of a water-borne crosslinking agent, 0.2-1 part of a water-borne leveling agent, 0.2-1 part of a water-borne defoamer, 0.3-3 parts of a water-borne hand feeling agent, and 0.5-5 parts of a thickener. The water-based surface treatment agent provided by the invention utilizes the high strength and good toughness advantages of graphene to greatly improve the tensile strength of automobile leather, adopts waterborne polyurethane to replace the traditional solvent-based polyurethane, eliminates the organicsolvent pollution from the source, eliminates potential safety hazards, improves the working environment of workers, and is eco-environment-friendly, thus enhancing the market competitiveness of automobile leather.

Description

technical field [0001] The invention belongs to the technical field of automobile leather surface treatment, and in particular relates to a high tensile strength water-based surface treatment agent for automobile leather and a preparation method thereof. Background technique [0002] Automotive Interior (Automotive Interior) mainly refers to the automotive products used in the interior modification of the car, involving all aspects of the car interior, such as car steering wheel covers, car seat cushions, car floor mats, car perfume, car pendants, interior decorations, storage boxes, etc. etc. are automotive interior products. [0003] What we call car interiors in China is actually the Interiors System in English. Because this part of auto parts has a certain degree of decoration, the usual translation in the industry is called "car interior". However, from the English "Interiors", we can know that these parts are not only for decoration, but they are very rich in functio...
