Color antistatic PVC (Polyvinyl Chloride) conveyor belt for electronic industry and manufacture method

Abstract

The invention relates to a color antistatic PVC (Polyvinyl Chloride) conveyor belt for the electronic industry and a manufacture method. The color antistatic PVC conveyor belt for electronic industry comprises a PVC surface layer and base materials, and is sequentially formed by an antistatic layer, a surface layer, a composite layer and a bottom layer from top to bottom, wherein the surface layer comprises base materials containing a PVC coating layer; and the bottom layer comprises base materials containing a PVC coating layer, and the base materials of the bottom layer are fabric mixed with at least 5 to 10% of conductive fibers. The manufacture method comprises the steps of: coating PVC paste on the upper bottom of the base materials; and coating the antistatic coat layer on at least one PVC surface layer. The base materials are the fabric mixed with 5 to 10% of conductive fibers, the surface resistance is 107 omega, the antistatic coat layer comprises 100 parts by weight of PVC paste resin, 50 to 70 parts by weight of plasticizing agents, 2 to 3 parts by weight of stabilizing agents, 10 to 15 parts by weight of antistatic agents and a proper amount of color paste, and the antistatic agents are semitransparent nonionic type antistatic agents containing glycerol single fatty aliphatic esters. Compared with foreign products, the color antistatic PVC conveyor belt has the advantages of low cost, adjustable finished product color and excellent antistatic performance.

Description

technical field [0001] The invention relates to the field of manufacturing methods of antistatic conveyor belts used in the electronics industry, in particular to a colored antistatic PVC conveyor belt used in the electronics industry and a manufacturing method thereof. Background technique [0002] Polyvinyl chloride (PVC) conveyor belt, as a light conveyor belt, has been widely used in the electrical and electronic industries due to its advantages of light weight, long life, good flame retardancy, and less friction. However, due to the high insulation of PVC, it also brings the problem of electrostatic hazards. When the PVC conveyor belt generates static electricity due to friction, due to its high surface resistance and low water absorption, the static electricity formed is not easy to eliminate. The accumulation of electrostatic voltage and capacity increases, which directly affects the performance of products in the electronics industry. [0003] The surface resistanc...

However, the decline of PVC resistivity is not in a linear relationship with the amount of carbon black added. When a certain amount of carbon black is added, even if carbon black is added, the change in conductivity is no longer significant.

At the same time, with the increasing amount of carbon black added, the tensile strength, impact strength, and elongation of PVC are greatly reduced, and the hardness is increased; at the same time, most PVC conveyor be...
