Abstract

The invention relates to rubber cement for aramid heat-resistant conveyer belt joints and a preparation method thereof and belongs to the technical field of rubber conveyer belt products. The rubber cement comprises ethylene-propylene-diene monomer rubber, reinforcing filler, vulcanizing agent, vulcanization accelerator, vulcanization activator, cross-linking agent, coupling agent, plasticizer and anti-ageing agent. After the ethylene-propylene-diene monomer rubber is plastified on an open mill, other components are added and mixed; after rubber cement preparation, the finished rubber cement for aramid heat-resistant conveyer belt joints is prepared. By considering from adhesion property, a designed formula system of the rubber cement provides ideal adhesion, meets the requirements on high-temperature application of conveying materials, enables conveyer belt joint quality to be greatly improved and its life to be greatly prolonged and enables reduction in aftersales maintenance cost.
