Abstract

The invention discloses water antistatic synthetic leather and a preparation method thereof. The synthetic leather is prepared from an antistatic sizing agent by adopting a rolling process, wherein the antistatic sizing agent is prepared by following components in parts by weight: 100 parts of water polyurethane resin, 5 to 10 parts of antistatic agent, 0.5 to 1 part of antifoaming agent, 0.5 to 1 part of flatting agent, 0.5 part of organic silicon dry sliding agent and 0.3 to 0.5 part of compatilizer, and the antistatic agent is a complex consisting of a quaternary ammonium cationic surfactant and a nonionic surfactant. The synthetic leather is not only relatively good in mechanical property and capable of improving tensile strength and impact strength of the product, realizing high filling and improving the processing rheological property, but also relatively excellent in antistatic characteristic.

Description

technical field [0001] The invention belongs to the field of synthetic leather manufacture, and in particular relates to a water-based antistatic synthetic leather and a preparation method of the water-based antistatic synthetic leather. Background technique [0002] Artificial leather and synthetic leather are the earliest substitutes invented for leather fabrics. It is made of PVC, plasticizer and other additives and calendered on cloth. At present, in the production process of domestic PVC decorative synthetic leather, plasticizers, PVC resin powder, heavy calcium, stabilizers, foaming agents, and other main raw materials are usually used. This kind of synthetic leather is prone to static electricity during the production process, especially the surface treatment process and organic solvents, causing fires. Its products are also prone to static electricity due to friction during use, which brings various safety hazards. The water-based anti-static synthetic leather prod...
