Embodiment 1

[0021] The raw materials of the antistatic slurry and their proportions by weight are: 100 parts of PVC resin powder, 15 parts of TPU resin, 8 parts of antistatic agent (composite of quaternary ammonium salt cationic surfactant and nonionic surfactant), 50 parts of epoxy soybean oil, 5 parts of color cake, 2 parts of potassium zinc stabilizer, 2 parts of azodicarbonamide, 30 parts of 2000 mesh superfine calcium carbonate.

[0022] According to the ingredients, the above-mentioned materials measured are input into the high-speed mixer through the pulse feeder, and the temperature is controlled at 100-150 ° C. After fully stirring, they enter the internal mixer, and the temperature is controlled at (150 ° C) for several minutes; After the base material (various fabrics) is opened, apply PU slurry (150°C), combine the fully mixed material with the base material with PU slurry, enter the second rolling mill (160°C) for kneading, and then After entering the four-roll calender (temp...

Abstract

The invention discloses antistatic synthetic leather and a preparation method thereof. The antistatic synthetic leather is prepared by a calendaring method with antistatic agent size. The antistatic agent size is made from the following components in parts by weight: 100 parts of PVC (Poly Vinyl Chloride) resin powder, 10-20 parts of TPU (thermoplastic polyurethane) resin, 5-10 parts of an antistatic agent, 40-60 parts of epoxidized soybean oil, 2-10 parts of a color cake, 3-7 parts of a stabilizing agent and a foaming agent, and 10-40 parts of superfine filler. The synthetic leather disclosed by the invention has the characteristics of good mechanical property and antistatic property.

Description

technical field [0001] The invention belongs to the field of synthetic leather manufacture, and in particular relates to an antistatic synthetic leather and a preparation method of the antistatic synthetic leather. Background technique [0002] Synthetic leather is the first invention to be used as a substitute 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. Contents of the invention [0003] The purpose of the present invention is to prov...
