Abstract

The invention discloses an anti-corrosion super-hydrophobic heat reflecting paint and a preparation method thereof. The anti-corrosion super-hydrophobic heat reflecting paint is prepared from the following raw materials: modified nano TiO2, modified nano SiO2, micron TiO2 and / or SiO2, fluorocarbon resin, a solvent, a curing agent, a defoaming agent, a wetting dispersant and a flatting agent. After experiments, the heat reflecting rate of the obtained product reaches 90 percent or more, the water contact angle reaches 145 degrees or more, and the product can meet the requirements on a coating under outdoor severe environments.

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...
