Abstract

The invention discloses a novel insulated sealing material for a chemical pump and a manufacturing method of the novel insulated sealing material. The novel insulated sealing material is prepared fromthe following raw material components in parts by weight: 89-113 parts of an organic fluorine thermoplastic elastomer, 8.5-13.5 parts of Al2O3, 45.5-61.6 parts of methicone, 27-49.5 parts of polypropylene, 17-27.5 parts of barium sulfate, 0.05-0.2 part of tetraethylenepentamine, 0.1-0.2 part of hexafluorobisphenol A, and 0.05-0.2 part of sulfonated-1,3-dibenzyl-2-methylimidazole. The novel insulated sealing material does not need to be vulcanized or only needs to be locally vulcanized, and can be machined in a circulating mode to form a thermoplastic vulcanized rubber system. The novel insulated sealing material has the active effects that by adjusting a formula and a manufacturing process, the breakdown voltage of a blend rubber material is increased, and meanwhile, it is ensured that indexes such as the hardness, mechanical performance, corrosion resistance and insulation resistance of the material meet the using requirements of the chemical pump.

Description

technical field [0001] The invention relates to the technical field of chemical pumps, in particular to a novel insulating and sealing material for chemical pumps. Background technique [0002] The pipeline cathodic protection system can effectively prevent pipeline corrosion. As a main component of the pipeline cathodic protection system, the chemical pump is mainly used to electrically insulate the pipelines at both ends of the chemical pump to prevent the loss of cathodic protection channel current and improve the pipeline cathodic protection effect. At the same time, reliable sealing is required to prevent medium leakage in the pipeline. When rubber products are in contact with chemical media, chemical corrosion occurs due to the decomposition of rubber and compounding agents due to chemical action, and sometimes it can also cause unbalanced swelling of rubber. The chemical substances entering the rubber break and dissolve the rubber molecules and cause the compounding ...
