Strong insulating material and preparation method thereof

Abstract

The invention discloses a strong insulating material and a preparation method thereof. The strong insulating material comprises a wearing layer, a barrier layer, an epoxy resin layer, a mica paper layer, an alkali-free glass fiber cloth layer and an antistatic layer from top to bottom, the wearing layer and the barrier layer are bonded by an adhesive, the mica paper layer and the alkali-free glassfiber cloth layer are bonded by the adhesive, and the alkali-free glass fiber cloth layer and the antistatic layer are bonded by the adhesive; the wearing layer is a polytetrafluoroethylene film; thebarrier layer is a polyvinylidene chloride film; the epoxy resin layer is formed by coating and curing of an epoxy resin coating; and the adhesive is prepared by uniformly mixing silicone resin, dibutyltin dilaurate and hexagonal boron nitride. The multilayer structure of the wearing layer-the barrier layer-the epoxy resin layer-the mica paper layer-the alkali-free glass fiber cloth layer-the antistatic layer improves the insulating performance, the thermal conduction performance and the heatproof and flame-retardant performances of the strong insulating material.

Description

technical field [0001] The invention belongs to the technical field of material chemical industry, and in particular relates to a strong insulating material and a preparation method thereof. Background technique [0002] With the progress and development of society, electricity has become an indispensable part of people's life, but the development of electricity also brings many risks and demands, which also directly promotes the development of insulating materials, which are mainly used in the power industry as Insulation and protection materials to prevent electricity from harming people and ensure safe operation. In addition to the conventional protective function of the electronics industry, insulation materials also need to protect and isolate different components to ensure that the electronic components can work normally without interfering with each other. .

Problems solved by technology

[0003] In some high-voltage power settings, in order to ensure safety, there are higher requirements for the insulation performance of insulating materials. Traditional materials have low dielectric strength and cannot effectively perform insulation effects in high-voltage environments. In order to greatly improve the insulation performance of insulating materials Insulation performance, it is necessary to increase the thickness and area of ​​the material, which will greatly increase the quality and volume of the insulator, thus affecting the preparation of insulating devices and the production of corresponding power settings, which is not in line with the current development trend of miniaturization and light weight of electrical equipment At the same time, the power industry will inevitably bring a lot of heat. In order to ensure the stability and safety of the insulating material, it is also necessary to endow the insulating material with good heat resistance and flame retardancy. In order to solve this problem, a strong insulation Material and preparation method thereof, the present invention provides the following technical solutions
