Rubber material with long service life and good mechanical properties

Abstract

The present invention discloses a rubber material with a long service life and good mechanical properties. Raw materials of the rubber material comprise in parts by weight: 60 to 75 parts of chloroprene rubber, 25 to 32 parts of ethylene-propylene-diene rubber, 1.5 to 2.3 parts of a titanate coupling agent, 1 to 2 parts of sulfur, 0.8 to 1.5 parts of accelerant 4010NA, 1.5 to 2.5 of dibenzothiazole disulfide, 1 to 1.8 parts of zinc oxide, 24 to 28 parts of ultrafine talc powder, 32 to 40 parts of modified bentonite, 18 to 23 parts of silicon carbide whisker, 15 to 30 parts of nano zinc oxide, 32 to 38 parts of furnace carbon black, 1 to 2 parts of calcium stearate, 1 to 2 parts of microcrystalline wax, 1.5 to 2 parts of antioxidant A, 1 to 2 parts of antioxidant D, and 1.5 to 2.3 parts of stearate. The rubber material provided by the present invention is excellent in mechanical properties and long in service life.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a rubber material with high service life and high mechanical performance. Background technique [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 b...

[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
