Fluorocarbon nanometer solar heat-insulation reflective paint, preparation method and using method thereof

Abstract

The invention relates to a fluorocarbon nanometer solar heat-insulation reflective paint, a preparation method thereof and a using method thereof. The paint can be used for roofs and glass curtain walls of the building industry, offshore drilling platforms, oil tanks and petroleum pipelines of the petroleum industry, the surfaces of cars and trains of the transportation industry, hulls and decks of the ship-building industry, and the tanks and warships of the weapon and aerospace industry. The fluorocarbon nanometer solar heat-insulation reflective paint comprises a component A and a component B, wherein the component A comprises the following materials in percentage by weight: 40%-70% of fluorocarbon resin, 1%-10% of nanometer TiO2 concentrated slurry, 10%-30% of infrared-ray reflective pigment, 3%-10% of hollow micro beads, 1%-5% of auxiliaries and 10%-20% of organic solvent; and the component B is cross-linking agent. The preparation method for the fluorocarbon nanometer solar heat-insulation reflective paint comprises the following steps: 1) preparing, dispersing and grinding the materials of the component A in proportion until the fineness is lower than 30 microns; and 2) mixing and curing the component A and the component B to prepare the fluorocarbon nanometer solar heat-insulation reflective paint. The fluorocarbon nanometer solar heat-insulation reflective paint provided by the invention is suitable for normal-temperature drying or low-temperature baking and drying; moreover, a coating film formed by the paint has the characteristics such as high reflectivity, a good heat-insulation effect, high corrosion prevention, high weather resistance, high self-cleanness, low friction and the like.

Description

technical field

[0001] The invention relates to the field of heat-insulating reflective coatings, in particular to a fluorocarbon nano-solar heat-insulating reflective coating and a preparation method and application method thereof. Background technique

[0002] According to the length of the wavelength, sunlight can be divided into ultraviolet light, visible light and infrared light. The wavelength of ultraviolet light is less than 400nm, accounting for about 5% of the total energy of the sun. The wavelength of visible light is 400nm-760nm, which accounts for about 45% of the total energy of the sun. The wavelength of infrared rays is greater than 760nm, accounting for about 50% of the total energy of the sun. It can be seen that solar energy is mainly concentrated in the visible light region and infrared region, and the heat-insulating reflective coating mainly reflects visible light and infrared rays.
