Graphene-based electromagnetic-radiation-resistant dual-component epoxy resin paint

Abstract

The invention relates to graphene-based electromagnetic-radiation-resistant dual-component epoxy resin paint. By means of dual radiation-resistant measures, the epoxy resin paint with excellent radiation resistance and yellowing resistance is obtained. The paint is composed of a component A and a component B according to the weight ratio of (2-6):1. The component A is prepared from, by weight, 20 parts of bisphenol-A epoxy resin, 80 parts of cycloaliphatic epoxy resin, 10-15 parts of graphene, 3-10 parts of antioxidant, 1-3 parts of ultraviolet absorbent, 10-22 parts of conductive filler, 2-5 parts of dispersing agent, 1-3 parts of pigment and 20 parts of solvent. The component B is prepared from, by weight, 20-30 parts of polyamide curing agent, 10-30 parts of hydrogenated cashew phenol modified phenolic amine and 20 parts of solvent. The paint curing product has excellent electromagnetic radiation resistance, yellowing resistance and adhesive force, proper hardness and excellent comprehensive performance and is better than similar products in the prior art.

Description

technical field [0001] The invention relates to an epoxy resin coating, in particular to a graphene-based anti-electromagnetic radiation two-component epoxy resin coating. Background technique [0002] With the improvement of living standards, various electrical appliances are increasing in the living environment, and TVs, computers, refrigerators, microwave ovens, etc. are all commonly used household appliances. However, the use of electronic products is accompanied by ubiquitous electromagnetic radiation. The accumulation of electromagnetic radiation from household appliances will have a chronic impact on the human body to a certain extent. How to reduce electromagnetic radiation has become a research hotspot. At the same time, the aging of the surface of electrical appliances is also an important factor affecting the service life of electrical appliances. Long-term air and photooxidation will cause distortion and chromatic aberration of the coating, which will affect the ...
