Abstract

The invention discloses a rubber compound used for rubber pipe outer layer rubber. The rubber compound is prepared from the following ingredients in percentage by mass: 100 parts of chlorinated polyethylene rubber, 2 to 4 parts of peroxide vulcanizing agents, 1.5 to 3 parts of vulcanizing agents, 8 to 12 parts of magnesium oxide, 30 to 50 parts of carbon black, 20 to 30 parts of dioctyl sebacate,2 to 4 parts of antimonous oxide, 3 to 5 parts of magnesium stearate, 1 to 2 parts of stearic acid, 3 to 5 parts of styrene resin, 0 to 2 parts of fatty primary amine, 4 to 8 parts of tri-tert-butoxide ethyl phosphate and 2 to 4 parts of Aktiplast M. The invention provides a preparation method of the rubber compound. The rubber compound and the preparation method have the beneficial effects that the rubber compound has good mechanical performance, good anti-aging and ozone-resistant performances; the Mooney viscosity is low; the processing extrusion performance is good; in addition, the cost is low. The preparation method of the rubber compound has simple operation; the mixing parameter can be easily controlled; the prepared rubber compound has stable performance.

Description

technical field [0001] The invention relates to the technical field of rubber production and processing, in particular to a rubber compound for rubber hose outer layer and a preparation method thereof. Background technique [0002] Rubber hoses, compared with hoses, focus on rubber hoses extruded from polymer chemical raw materials through vulcanization and other processes. The hose structure is usually divided into: inner rubber layer, outer rubber layer and skeleton layer (or middle layer). The inner rubber layer directly bears the abrasion and erosion of the conveying medium; the outer rubber layer protects the inner body of the rubber hose from damage and erosion of the external environment; the skeleton layer is the pressure-bearing layer of the rubber hose, giving the hose body strength and rigidity. The working pressure of the hose depends on the material and structure of the skeleton layer. [0003] Common materials used for the inner and outer rubber layers of hos...
