Problems solved by technology

However, the cashew amine curing agent requires Mannich reaction for synthesis, and the toxic chemical substance formaldehyde solution is used in the synthesis process. Although the toxicity is a little lower, it still has a harmful effect on human health, and after the curing agent is synthesized, it can be used The cost is high, and the application of epoxy resin does not meet the market demand

Abstract

The invention provides an epoxy resin composition used for shielding a deep well submersible pump and a casting method thereof, belonging to the technical field of polymer material application and solving the problems that the existing epoxy resin curing agent has toxicity and high cost. The epoxy resin composition used for shielding the deep well submersible pump comprises the following components by weight portions: 100 portions of bisphenol A epoxy resin, 50 to 120 portions of cashew nut shell oil curing agent, 100 to 300 portions of packing, and 0.1 to 5 portions of curing promoter. The casting method comprises the following steps: A. stirring; B. vacuum casting; and C. curing. The epoxy resin composition used for shielding the deep well submersible pump has wide material source, low price and no toxicity; the casting method adopts the epoxy resin composition as an encapsulating material for shielding a motor stator of the deep well submersible pump and can have effects of insulation, fixing, damping, heat resistance and sealing.

Description

technical field [0001] The invention relates to an epoxy resin composition, in particular to an epoxy resin composition for shielding a deep well submersible pump and a pouring method thereof; it belongs to the technical field of polymer material application. Background technique [0002] Epoxy resins generally refer to organic polymer compounds containing two or more epoxy groups in their molecules, and their relative molecular weights are not high except for a few. The molecular structure of epoxy resin is characterized by active epoxy groups in the molecular chain, and the epoxy groups can be located at the end, middle or ring structure of the molecular chain. Due to the active epoxy groups in the molecular structure, they can undergo cross-linking reactions with various types of curing agents to form insoluble, infusible high polymers with a three-dimensional network structure. Epoxy resins are generally used together with additives to obtain application value. Additiv...
