Abstract

The invention discloses an epoxy resin sealant and a preparation method and application thereof. The epoxy resin sealant comprises a component A and a component B, the component A comprise, by weight,75-80 parts of bisphenol F-type epoxy resin, 7-10 parts of bisphenol A-type epoxy resin, 1-1.2 parts of silane coupling agents and 10-15 parts of diluent, and the component B comprises, by weight, 30-35 parts of curing agents, 25-30 parts of accelerant I, 20-25 parts of accelerant II and 12-17 parts of solvent. By optimizing the components and ratios of raw materials of the epoxy resin sealant, adhesive property and acid corrosion resistance of the epoxy resin sealant can be improved effectively, and accordingly the epoxy resin sealant is enabled to be applicable to sealing of polyphenyl ether groove covers of lead-acid storage batteries.

Description

technical field [0001] The invention relates to the technical field of epoxy resin sealant, in particular to an epoxy resin sealant and its preparation method and application. Background technique [0002] Polyphenylene oxide (PPO) is one of the five general-purpose engineering plastics in the world. It has the advantages of high rigidity, high heat resistance, flame retardancy, high strength, and excellent electrical properties. In addition, PPO also has the advantages of wear resistance, non-toxicity and pollution resistance. The dielectric constant and dielectric loss of PPO are one of the smallest varieties among engineering plastics, and they are hardly affected by temperature and humidity, and can be used in low, medium and high frequency fields. Therefore, the application of PPO in lead-acid batteries has attracted more and more attention. [0003] The molded and extruded products of polyphenylene ether and modified polyphenylene ether are usually bonded with solven...
