Abstract

The invention provides fire-proof antistatic a V-belt tape frictioning, which adopts neoprene adhesive variety which has excellent fire-proof property, adds traditional natural gum, butylbenzene rubber and neoprene adhesive in order to modify process property, then adds various fire retarding agent which has excellent antistatic and fire-proof property, wherein fire-proof property can respectively reach that flame combustion average time is no more than 5 seconds, and flameless combustion average time is no larger than 7 seconds, and simultaneously meets the base process technique property of V-belt and various physical mechanical properties which are required by the criterion.

Description

technical field [0001] The invention relates to a flame-retardant and antistatic v-belt wrapping cloth wiping glue and a preparation process thereof. Background technique [0002] Flame retardant and antistatic V-belts for coal mines are generally composed of primer, buffer rubber, polyester cord and wrapping cloth according to different product models and sizes. [0003] However, the existing ordinary V-belts have poor flame-retardant and static-conductive properties, and are easy to burn. When used in coal mines, static electricity is easily generated due to friction, and they are ignited and burned, resulting in safety accidents. Contents of the invention [0004] The object of the present invention is to provide a flame retardant and antistatic v-belt wrapped cloth wiping glue, which has excellent flame retardant performance and good electrical conductivity, less heat generation, fast heat conduction, and reliable safety performance. [0005] Another object of the pre...
