Embodiment 1

[0019] A method for preparing an insulating, antistatic, and highly reflective water-based paint, comprising the following steps: 1. Weighing graphene oxide and sodium acetate trihydrate according to the ratio, and uniformly dispersing them in an aqueous solution of ethylene glycol with a mass fraction of 25%, magnetically After stirring for 10~15min, add thioacetamide, stir for another 10~15min, add zinc sulfide and potassium carbonate, put the mixed liquid into a ball mill tank for ball milling for 10h, dry the slurry at 90°C for 3~5h, vacuum freeze dry for 1h, put In the crucible, heat up to 200°C at a heating rate of 15°C / min in a microwave high-temperature muffle furnace, keep it warm for 10 minutes and then cool it down. Evenly dispersed solution, after cooling, washed repeatedly with ethanol, and then dried in a blast drying oven at 60°C for 10~12h to obtain graphene whisker composite material; 2. Under nitrogen protection, epoxy resin , 4-dimethylaminopyridine, etc., m...

Abstract

The invention discloses a method for preparing an insulating antistatic high-reflectivity waterborne coating which is composed of the following components: an epoxy resin, 4-dimethyl aminopyridine, graphene oxide, terpene phenolic resin, acrylic acid, ethylene glycol, butyl acrylate, hydroxy calcium phosphate, magnesium hydroxide whisker, pure water, triethanolamine, polyacetylene, vinyl ester resin, sodium acetate trihydrate, an ethylene glycol aqueous solution, thioacetamide, zinc sulfide, potash, a curing agent, a dispersing agent, a defoamer and a leveling agent. The waterborne solvent coating disclosed by the invention is free of volatile organic compound, compared with other coatings, the coating is small in pollution to the environment and high in reflectivity, and not only can assist a lamp to emit strong and bright light, but also has stable and excellent high reflectivity, and the high-reflectivity waterborne coating additionally has excellent impact resistance and flexibility, is very good in corrosion resistance and ultraviolet resistance and is also simple and convenient to use.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a preparation method of an insulating, antistatic, and highly reflective water-based coating. Background technique [0002] 99.99% of the energy in sunlight is concentrated in the visible light region, ultraviolet region and infrared region. If generally divided, the visible light region accounts for 50% of the energy, the ultraviolet region accounts for 7%, and the infrared part accounts for about 43%. Visible light itself has little heat, and the main source of heat is caused by infrared radiation in sunlight. Traditional heat dissipation modes mainly include heat conduction, convection and heat radiation. However, for many fields such as photovoltaic modules and building exterior walls, due to the limitation of space, material environment and cost, it is often not suitable to use convection and heat conduction to dissipate heat. The method of infrared reflection does not ha...
