Problems solved by technology

[0002] At present, the traditional flat vulcanization method produces rubber-surfaced whole-core flame-retardant conveyor belts. Due to low wear resistance, poor flame-retardant and anti-static properties of its components, it is a waste of resources during application. In addition, due to the complicated production methods or processes, The production efficiency is low, so it is very necessary to develop a new special material for flame-retardant conveyor belt cover rubber

Abstract

The invention discloses a special material for mine-used flame retardant conveyor belt covering glue and a making method thereof. The components in portion by content of the special material are: 30 to 50 portions of polyvinyl chloride resin, 10 to 30 portions of powdered butyronitrile rubber, 0.3 to 0.5 portions of carbon black, 10 to 30 portions of flame retardant system, 30 to 50 portions of plasticization system, 1 to 3 portions of lubrication system, 2 to 5 portions of stabilization system, 2 to 4 portions of antistatic system and 5 to 8 portions of crosslinking agents. The making process comprises the following steps that: (1) raw materials are weighed and then put into a high-speed mixing machine, the machine is turned on for high-speed mixing, the mixing temperature is controlled to be about 90 DEG C, the mixing time is not more than 15 minutes, and after uniform plasticization, a material discharge valve is opened to discharge material; (2) the raw materials well mixed are put into a material bucket of an extruder, then the preheated extruder is turned on, and the rotational speed is controlled to be between 60 and 80 rpm; and (3) after extrusion, the raw materials are air-cooled, granulated and air-conveyed, and then finished products are packaged. The special material for mine-used flame retardant conveyor belt covering glue is mainly applicable to adopt the extruder extrusion method to produce rubber-covering whole-core flame retardant conveyor belts, and is also applicable to a plate vulcanization method for producing the rubber-covering whole-core flame retardant conveyor belts. When the extrusion method is adopted to produce the rubber-covering whole-core flame retardant conveyor belts, the production process parameters are basically similar to that of whole-core flame retardant conveyor belts produced through an extrusion process (the temperature of the extruder and molds are slightly higher).
