Coating for reflective lampshade and preparation method

Abstract

The invention discloses a coating for a reflective lampshade and a preparation method. The coating is prepared from the following components: graphene modified polyacrylic resin, epoxy resin, nanosilicon dioxide, aluminum hydroxide, magnesium oxide, titanium dioxide, a defoaming agent, a filler, a modifier, and appropriate amount of water. The preparation method comprises the steps of mixing and modifying the graphene modified polyacrylic resin and the epoxy resin; adding the nanosilicon dioxide, titanium dioxide, the modifier, the defoaming agent and the appropriate amount of water for mixing and reacting; grinding to the particle size being under not larger than 20um; adding the aluminum hydroxide, the magnesium oxide and the filler, mixing and shearing to obtain the coating for the reflective lampshade. The coating for the reflective lampshade provided by the invention not only has better high temperature resistance and corrosion resistance, but also has better light reflection and concentration functions, can effectively utilizes a light source so as to reduce the waste of the light source, and has a better energy-saving effect and a better application value.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a coating for reflective lampshades and a preparation method. Background technique [0002] Fluorescent tubes are regarded as the most popular lighting fixtures in the world, especially in office buildings, factory production lines, shopping malls, schools, hospitals, parking lots, etc. The utilization rate is as high as 90%. 360-degree angle projection, and part of the light irradiated on the ceiling is invalid light (the light source that is not projected on the area that needs to be illuminated is invalid light), so generally designers will use shiny metal (such as thin aluminum) on the surface, or paint Reflective chemical substances (such as aluminum oxide, barium sulfate, etc.) on the surface are used for light reflection. However, any metal or reflector coated with chemical substances will be oxidized and deteriorated once it is in contact with the air for a long time. C...

[0002] Fluorescent tubes are regarded as the most popular lighting fixtures in the world, especially in office buildings, factory production lines, shopping malls, schools, hospitals, parking lots, etc. The utilization rate is as high as 90%. 360-degree angle projection, and part of the light irradiated on the ceiling is invalid light (the light source that is not projected on the area that needs to be illuminated is invalid light), so generally designers will use shiny metal (such as thin aluminum) on the surface, or paint Reflective chemical substances (such as aluminum oxide, barium sulfate, etc.) are used for light source reflection. However, any metal or reflector coated with chemical substances will be oxidized and deteriorated once it is in contact with the air for a long time. Corroded by acid, alkali and other chemical substances in the air, if it is a paint, it will peel off due to temperature and oxidation, and lose its reflective ability
