A kind of rubber sealing material for chemical pump

Abstract

The invention discloses a chemical pump used rubber sealing material. The chemical pump used rubber sealing material is characterized by being prepared from the following ingredients: butadiene styrene rubber, fluororubber, polyethylene glycol, stearic acid, an anti-aging agent, sulfur, polypropylene and a modified filler. Compared with the prior art, the chemical pump used rubber sealing material prepared by the invention has the advantages of good flexibility, low density, compression resilience, wide temperature using range and the like, also has the advantages of higher tensile strength, tearing strength and abrasive resistance, large elasticity modulus, high temperature resistance, chemical corrosion resistance, good heat-conducting property, low thermal expansion coefficient and the like and has self-lubricating property; all the ingredients are uniformly dispersed in the sealing material, therefore, the stability is high, so as to further improve the property of the sealing material; the heat dispersion of the sealing material can be greatly improved through the synergistic effect of all the ingredients and the modified filler, so as not to generate the phenomenon of temperature accumulation.

Description

technical field [0001] The invention relates to the technical field of sealing rubber, in particular to a rubber sealing material for chemical pumps. Background technique [0002] Whether the chemical pump is good or bad, in addition to the material and structure of the chemical pump meeting the requirements of the working medium, the choice of sealing structure and form is also crucial. 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...
