Into rubber material, such as nitrile rubber, neoprene, butyl rubber, EP rubbers.
Neoprene has good caking property, is a kind of important rubber material for Transmission belt base rubber, in addition, chlorine
Buna has good mechanical property and the performances such as excellent oil resistant, heat-resisting, resistant to chemical etching, however, neoprene
High load performance especially deflects poor-performing, as Transmission belt base rubber in use, being difficult under high stress and strain
Maintain its mechanical property constant under the use environment of high load, so, the prior art mainly adopts add auxiliary agent thereto, fill out
The additives such as material or reinforcing fiber are to enhance its performance under high load use environment, for example, leading in CN107057145A
It crosses and Fypro and viscose fiber is added into the mixed rubber based on neoprene to enhance the high load of rubber material
Performance, fiber therein bear main stress load so that and the high load performance of rubber material increases,
Phenolic resin and the carbon fiber line of rubber constituent are attached with by adding in surface into rubber in CN104956000A, is utilized
The high intensity of carbon fiber line, obtained up to ten thousand stretching experiments for carrying load of rubber material experience, mechanical property conservation rate
More than 80% can be reached, however, using above-mentioned material as Transmission belt base rubber, the resistance to ag(e)ing in the use environment of high load
Can and it deflect that number is still relatively low, and hydraulic performance decline is still more serious after long-time use.
Those skilled in the art is needed on the basis of existing technology by improving the formula of rubber and additive, into one
Step improves the high load performance of rubber material, especially chloroprene rubber material, makes that it is suitable for as high load conveyer belt
Primer uses, moreover, additive therefor, into should be relatively low, processing technology should be as easy as possible.
