Abstract

The invention belongs to the technical field of chemical coatings, and particularly relates to novel epoxy resin paint and application thereof. The novel epoxy resin paint is prepared from the following raw materials in parts by weight: 80-100 parts of modified waterborne epoxy resin, 30-40 parts of modified epoxidized soybean oil, 5-8 parts of a fixing agent, 60-80 parts of an epoxy resin curingagent, 3-6 parts of a heat dissipating agent and 110-160 parts of water. The preparation method comprises the following steps: mixing the modified waterborne epoxy resin, the modified epoxidized soybean oil and water, heating the components to 35-40 DEG C, carrying out heat preservation treatment for 25-30 minutes, cooling, sequentially adding the fixing agent, the heat dissipating agent and the epoxy resin curing agent, and stirring the components for 2-3 hours to obtain the epoxy resin paint. The novel epoxy resin paint provided by the invention is high in heat resistance and good in heat conductivity, has a very good fixing and adsorbing effect on volatile organic compounds generated by the novel epoxy resin paint in a high-temperature environment, is high in safety and good in environmental protection property, and can be used as outdoor and indoor terrace paint.

Description

technical field [0001] The invention belongs to the technical field of chemical coatings, in particular to a novel epoxy resin paint and its application. Background technique [0002] Oxygen resin is a kind of resin with excellent performance. It has excellent dielectric properties, mechanical properties, bonding properties and corrosion resistance, and its curing shrinkage rate and thermal expansion coefficient are small, which makes epoxy resins widely used. Epoxy resin paint is a coating with epoxy resin as the main film-forming substance. There are many types, each with its own characteristics. According to the curing method, there are white dry one-component, two-component and multi-component liquid epoxy coatings; baking one-component and two-component liquid epoxy coatings; powder epoxy coatings and radiation-cured epoxy coatings. According to the coating state, there are solvent-based epoxy coatings, solvent-free epoxy coatings and water-based epoxy coatings. When...
