Rubber sealing material for magnetic pump

Abstract

The invention discloses a rubber sealing material for a magnetic pump. The rubber sealing material is characterized by being prepared from the following ingredients: nitrile rubber, fluorine rubber, silicon rubber, dibutyl phthalate, anti-aging agents, sulphur, polypropylene and modified fillers. Compared with the prior art, the prepared rubber sealing material for the magnetic pump has the advantages that the process property of the rubber sealing material is improved; the environment-friendly effect is achieved in the production process; the finished product qualification rate reaches up to 98 percent; the advantages of flexibility, low density, compression resilience, wide use temperature range and the like are realized; the cost is low; the economic income is high; the advantages of higher tensile strength, higher tearing strength, higher abrasion resistant performance, great elasticity modulus, high temperature resistance, chemical corrosion resistance, good heat-conducting performance, low thermal expansion coefficient and the like are also realized.

Description

technical field [0001] The invention relates to the technical field of sealing rubber, in particular to a rubber sealing material for a magnetic pump. Background technique [0002] The quality of the magnetic pump, in addition to the material and structure of the magnetic pump to meet the requirements of the working medium, the choice of sealing structure and form is also very important. Reasonable selection of sealing structure and form is the key to ensure normal and orderly production, reduce maintenance and repair costs, reduce engineering labor intensity, reduce material waste, and avoid environmental pollution. The sealing material refers to the material that can withstand the joint displacement to achieve the purpose of airtightness and watertightness and is embedded in the building joints. The early sealing materials are mainly fabrics, mineral fibers or felts. With the development of industrial technology and increasingly complex and diverse requirements, sealing m...
