Forming technology of outdoor epoxy resin composite material product

Abstract

The invention discloses a forming technology of an outdoor epoxy resin composite material product. The forming technology comprises the steps that S1, an inner mold is installed, specifically, an iron core and a winding which need to be subjected to insulation packaging are installed in the inner mold to serve as a semi-finished inner container product; S2, curing and forming are conducted on the semi-finished inner container product,inner mold vacuum pouring and automatic pressure gel injection are conducted by adopting an epoxy resin composite material, and curing and forming are conducted in a drying oven to prepare an inner container; S3, the surface of the semi-finished product is cleaned, and a surface release agent is cleaned away; S4, the surface of the semi-finished product is coated with a coupling agent; S5, an outer mold is installed, and the outdoor epoxy resin composite material semi-finished product coated with the coupling agent is installed in the outer mold; and S6, silicone rubber filling and curing forming are conducted. According to the forming technology, the cost is greatly reduced in the industry, the reliability is high, the weather resistance is excellent, the technology efficiency is high, no connection position exists, the electrical property, the waterproofness, the mechanical strength and the like are more reliable, a plurality of molds of a plurality of silicone rubber sheets with different shapes do not need to be manufactured, and only one outer mold is needed.

Description

technical field [0001] The invention relates to the technical field of electrical product processing, in particular to a molding process for outdoor outdoor epoxy resin composite material products. Background technique [0002] The current outdoor transformers (including current transformers and voltage transformers) generally adopt the following processes: outdoor epoxy resin composite materials are cured and formed, indoor epoxy resin composite materials are cured and sprayed with outdoor paint, indoor epoxy resin composite materials are cured and formed After the resin composite material is cured and formed, it is divided into multiple pieces of adhesive silicone rubber sheets according to the shape of the product. The above three processes have their own advantages and disadvantages. The curing molding process of outdoor epoxy resin composite materials is simple in one-time molding process, the price of materials is high, and the weather resistance is poor. After a few y...

Problems solved by technology

The above three processes have their own advantages and disadvantages. The curing molding process of outdoor epoxy resin composite materials is simple in one-time molding process, the price of materials is high, and the weather resistance is poor. After a few years, the surface of the product will be powdered; The process of spraying outdoor coatings after curing is low in price and easy to operate, but the weather resistance of the coatings is relatively poor, and because the life of the coatings is generally only 5 to 7 years, the products of this process need to be renewed regularly. The adhesion of the coating in the epoxy resin is high; after the indoor epoxy resin composite material is cured and formed, it is divided into multiple pieces according to the shape of the product. The process of sticking silicone rubber sheets is better than the above two processes due to the excellent weather resistance of silicone rubber. Good, and the material price is much lower than outdoor epoxy resin composite materials, but there are also disadvantages such as complex process, special-shaped products need to be bonded multiple times, product appearance has splicing positions, and the two materials may not fit well enough.
