Abstract

The invention discloses epoxy resin coating and a preparation method thereof. Compared with a market product, the epoxy resin coating prepared by the preparation method has higher toughness, higher elasticity, better anti-corrosion effect, higher weather resistance, higher temperature resistance, better fluidity and higher flame resistance, and is non-toxic, low-carbon and environment-friendly.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to an epoxy resin paint and a preparation method thereof. Background technique [0002] Epoxy resin paint is a paint with epoxy resin paint as the main film-forming substance. Strong adhesion, excellent chemical resistance, corrosion resistance, water resistance, thermal stability and electrical insulation, widely used in construction, chemical industry, automobiles, ships, electrical insulation, etc. [0003] Epoxy resin itself has a thermoplastic linear structure. After being heated, the solid resin can soften and melt, and become viscous or liquid; the viscosity of liquid epoxy resin decreases after heating; only after adding a curing agent to cure, the epoxy resin can be used. . A complete conceptual epoxy resin composition system should be composed of four components: 1. Resin components (epoxy resin and curing agent), 2. Modified components (plasticizers, toughener...
