Embodiment 1

[0020] refer to figure 1 as shown,

[0021] A static casting process for epoxy resin pot insulators, comprising the following steps: raw material configuration, mold heating, pouring, curing and product demoulding, the raw material configuration includes epoxy resin, filler, curing agent and plasticizer for mixing Heating, wherein the plasticizer is a polyamide resin;

[0022] Heat the mold to be poured to prevent sink marks of the epoxy resin mixture during pouring due to excessive temperature difference between the mold and the epoxy resin mixture;

[0023] Fix the mold to be poured and pour the mixed raw materials into the interior of the mold;

[0024] The raw material mixed inside the mold is transferred from a liquid state to a hot solid state, usually using a two-step curing process, that is, pre-curing at a lower temperature and post-curing at a higher temperature. The solidification process at this time is the conversion process from the liquid state of the mixture...

Abstract

The invention discloses a static pouring process of an epoxy resin basin-type insulator. The static pouring process is characterized by comprising the following steps of raw material preparation, mold heating, pouring, curing and product demolding; according to raw material preparation, epoxy resin, filler, a curing agent and a plasticizer are mixed and heated, wherein the plasticizer is epoxidation vegetable oil of increase functional groups and and one or more of multifunctional thermoplastic polyamide resin, polysulfide rubber and polyester; a mold to be poured is heated; the mold to be poured is fixed, and the mixed raw materials are poured into the mold; and the plasticizer is added into the epoxy resin before pouring so as to improve the brittleness of the cured epoxy resin and prevent a cured body from being broken, meanwhile, the plasticizer adding process and the epoxy resin feeding process are carried out together, the problems that the heating time is short and sufficient mixing cannot be achieved are avoided, cracks happening to an epoxy resin layer are reduced, and the problems that the electrical performance of the insulator is affected and potential safety hazards are possibly caused are avoided.

Description

technical field [0001] The invention belongs to the technical field of epoxy resin pot insulators, and in particular relates to a static pouring process for epoxy resin pot insulators. Background technique [0002] According to China's recent plan, the power market will continue to develop, and the scale of power demand and power grid construction will also expand day by day. With the demand for electricity and the construction of the power grid, the use of high-voltage switches is increasing, and the scale of epoxy resin cast pot insulators is increasing day by day. The product quality and yield are becoming more and more important tasks for epoxy cast parts. The pot insulators produced by this method often have poor toughness, and cracks may appear in the epoxy resin layer under long-term use, affecting the electrical performance of the insulator, and may cause safety hazards. Contents of the invention [0003] The purpose of the present invention is to provide a static...
