Problems solved by technology

[0002] With the rapid development of the industrial field, traditional rubber materials can no longer meet the demand. The filling of inorganic rigid particles is one of the rubber modification technology methods. The cost of rubber modified by filling inorganic rigid particles is greatly reduced. Due to the rich bentonite resources , cheap, widely used in rubber products as an inorganic filler, bentonite, also known as bentonite, bentonite, superfine talcum powder, is a non-metallic mineral with wide application and large consumption in national economic construction Resources, since the 1970s, the application of bentonite in rubber has entered a new level of development. In fact, the mechanical properties of rubber after bentonite filling are average. With the increase of bentonite filling, this defect becomes more and more obvious, and the service life of rubber Shorter, how to prepare a kind of rubber material with good mechanical properties and long service life has become a technical problem to be solved at present
