Abstract

The invention discloses a corrosion-resistant super-hydrophobic heat-reflecting coating and a preparation method thereof, which is composed of the following raw materials: modified nano-TiO2, modified nano-SiO2, micro-TiO2 and / or SiO2, fluorocarbon resin, solvent, curing agent, defoamer, wetting and dispersing agent and leveling agent. After the present invention is tested, the thermal reflectance of the obtained product reaches more than 90%, and its water contact angle reaches more than 145°, which can meet the requirements for the coating in the harsh outdoor environment.

Description

technical field [0001] The invention relates to a corrosion-resistant super-hydrophobic heat-reflecting coating and a preparation method thereof, in particular to a modification method and ratio research of one or more pigments and fillers. Background technique [0002] With the acceleration of the pace of social industrialization and the great application of high-tech, the past energy-consuming and polluting production methods have been gradually eliminated, replaced by various low-energy, high-efficiency and in line with the scientific concept of development. ways to produce. In modern society, places like oil pipelines, oil storage equipment and cold storage do not have a high demand for solar heat. On the contrary, refrigeration equipment needs to be maintained from time to time, which wastes a lot of manpower and material resources. The application of heat reflective coatings should be applied And born. At the same time, due to the special use environment, the coating...
