Waterborne epoxy resin antirust paint and preparation method thereof

Abstract

The invention relates to the technical field of high molecular materials and in particular relates to waterborne epoxy resin antirust paint and a preparation method thereof. The waterborne epoxy resinantirust paint is prepared from the following components in parts by weight: 40 to 60 parts of epoxy resin emulsion, 30 to 40 parts of de-ionized water, 0.1 to 0.8 part of a corrosion inhibitor, 0.2to 1 part of a dispersant, 35 to 40 parts of pigment and filler, 0.1 to 0.5 part of a de-foaming agent, 1 to 2 parts of a film-forming agent, 0.5 to 1 part of a thickening agent and 3 to 5 parts of asilane coupling agent. The high-performance waterborne coating adopts auxiliary agents including the epoxy resin emulsion, the silane coupling agent, the thickening agent, the corrosion inhibitor, thefilm-forming agent and the like so that the waterborne epoxy resin antirust paint has excellent performance.

Description

Technical field: [0001] The invention relates to the technical field of polymer materials, in particular to a water-based epoxy resin antirust paint and a preparation method thereof. Background technique: [0002] All kinds of mechanical equipment need to be coated with a layer of metal paint, on the one hand to increase the appearance, and on the other hand to prevent dust, rust and corrosion; the anti-rust paint in the prior art contains a large amount of volatile organic solvents, which produces a large amount of toxic and harmful Volatile gases pollute the air and damage human health. Stability is ubiquitous, easy to fall off, not suitable for complex and harsh environments. [0003] As people pay more and more attention to environmental protection, safety production, etc., as well as awareness of sustainable and healthy development, countries all over the world have higher and higher environmental protection requirements for coatings, and the level of harmful substance...
