Nanometer silicon dioxide modified epoxy resin coating

Abstract

The invention discloses a nanometer silicon dioxide modified epoxy resin coating. The nanometer silicon dioxide modified epoxy resin coating comprises the following raw materials by weight: 55 to 70 parts of epoxy resin, 8 to 15 parts of chlorinated rubber, 5 to 18 parts of silicone resin, 9 to 15 parts of alkyd resin, 1 to 3 parts of graphene oxide, 3 to 8 parts of nanometer silicon dioxide, 2 to8 parts of charcoal powder, 1 to 3 parts of silicon carbide, 0.3 to 1.8 parts of nanometer titanium black, 2 to 6 parts of precipitated barium sulfate, 0.7 to 3 parts of bamboo fiber, 3 to 9 parts ofbasalt flakes, 2 to 8 parts of nanometer aluminium oxide, 9 to 25 parts of a curing agent, 0.1 to 1 part of 1-pyrenebutyric acid, 20 to 30 parts of a solvent and 0.2 to 1.5 parts of an auxiliary agent, wherein the curing agent is a mixture of n-butyl trimellitate anhydride, 2-ethyl-4-methyl imidazole, zinc acrylate and a boron-amine curing agent 594. The nanometer silicon dioxide modified epoxy resin coating provided by the invention has high strength, good heat resistance and wear resistance and excellent corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a nano silicon dioxide modified epoxy resin coating. Background technique [0002] Epoxy resin is one of the most commonly used thermosetting resins. It has excellent adhesion, corrosion resistance, and high strength. Epoxy resin coatings made of it have been widely used in automobiles, shipbuilding, aviation, machinery, etc. , chemical industry, large-scale water conservancy projects and civil construction industries; however, epoxy resin has poor heat resistance and poor wear resistance, and the coating made with it has the defect of unsatisfactory heat resistance and wear resistance of the coating film. limit its application. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a nano-silica modified epoxy resin coating, which has high strength, good heat resistance and wear resistance, and excellen...
