Problems solved by technology

[0005] However, the current research on epoxy coatings is still focused on the improvement of a single performance. While overcoming the shortcomings of epoxy resin itself such as brittleness and flammability, it is necessary to further improve its insulation and develop a comprehensive performance. Oxygen resin is an inevitable trend to improve its application prospects

Abstract

The invention relates to a high-insulation high-flame-retardant double-component epoxy coating. The coating is characterized by being formed by mixing and curing a component A and a component B according to a weight ratio of 1: 1 to 1: 1.5 during use, wherein the component A is mainly prepared from the following components in percentage by weight: 10.0%-50.0% of organic silicon modified epoxy resin, 15.0%-40.0% of nano-SiO2 toughened epoxy resin, 10.0%-20.0% of a first plasticizer and 15.0%-40.0% of aluminum hydroxide; and the component B is mainly prepared from the following components in percentage by weight: 5.0%-25.0% of an amine curing agent, 10.0%-20.0% of a second plasticizer, 20.0%-50.0% of polyphosphate and 20.0%-50.0% of polytetrafluoroethylene. The coating has good insulating and flame-retardant properties.

Description

technical field [0001] The invention relates to an epoxy resin coating, in particular to a high-insulation and high-flame-retardant two-component epoxy coating and a preparation method thereof.
