Abstract

The invention discloses a preparation method of a nano-modified solvent-free epoxy ceramic coating material. The nano-modified solvent-free epoxy ceramic coating material comprises a component A and acomponent B, wherein the component A is a main material, and comprises 35-70% of a liquid-state epoxy resin, 11-27% of silicon carbide, 15-25% of precipitated barium sulfate, 2-7% of ceramic micropowder, 1.6-5% of a nano-modified epoxy resin and 0.4-1.0% of an antifoaming agent. According to the invention, breakthrough improvement is carried out on the prior art, the nano-modified epoxy resin isuniformly dispersed into the liquid epoxy resin to form the nano-modified solvent-free epoxy resin, and the nano-modified solvent-free epoxy resin is used for preparing the nano-modified solvent-freeepoxy ceramic coating material; and the product not only solves the problems of viscosity and sagging of the solvent-free epoxy ceramic coating material, but also improves the impact strength and flexibility of the solvent-free epoxy ceramic coating material and the properties of corrosion resistance, protection performance and the like of the product.

Description

technical field [0001] The invention relates to the technical field of solvent-free epoxy materials, in particular to a method for preparing a nano-modified solvent-free epoxy ceramic coating. Background technique [0002] Coatings and adhesives prepared from epoxy resins are widely used in national defense, petrochemical, machinery, electronics and other fields. In actual use, volatile solvents (VOCs) are used to dissolve and use, volatile solvents (VOCs) cause environmental pollution, and production and use are prone to safety hazards; due to the use of emulsifiers, water-based epoxy resins have poor comprehensive anti-corrosion and protection properties , to limit its field of use. As a result, solvent-free epoxy materials have received great attention and favor. [0003] Chinese patent ZL 02 1 55418.8 introduces a solvent-free epoxy ceramic coating, which is made of epoxy resin as the main material, adding quartz powder and additives, and the curing agent is composed o...
