Abstract

The invention discloses a thermal-inductive fluorocarbon function coating containing an azobenzene/carbon-hybrid material and a preparation method of the thermal-inductive fluorocarbon function coating. The coating is prepared from the following components: 40 to 60 parts of fluorocarbon resin, 10 to 20 parts of crosslinking resin, 15 to 20 parts of mixed solvent, 10 parts of pigment, 5 to 15 parts of the azobenzene/carbon-hybrid material, 0.5 part of delustering agent, 0.1 part of flatting agent, 0.15 part of defoaming agent, 0.25 part of dispersant and 0.00035 part of curing agent. The coating disclosed by the invention has the advantages that light energy, such as solar energy, stored in an illumination process is released in the form of heat under the condition without illumination through photo-thermal storage conversion, so that the problem that a fluorocarbon material has no heat self-storage/release function under special environments is solved, and the power consumption is greatly reduced; the coating can be widely applied to the fields of architecture, electrical and electronic industries, aerospace industry and the like; as a new and green energy, the coating has immeasurable application prospects and economic benefits for dealing with the global energy crisis.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a thermally sensitive fluorocarbon functional coating containing an azobenzene / carbon hybrid material and a preparation method thereof; a thermally sensitive coating and a preparation method applied to the outer layer of high-end precision machinery such as aerospace. Background technique [0002] Fluorocarbon resin has a strong C-F bond as the skeleton. Compared with other resins, it has better heat resistance, chemical resistance, cold resistance, low temperature flexibility, weather resistance and electrical properties, and because of its good crystallinity , so it is non-adhesive and non-wetting. Widely used in kitchen and cooking utensils, molding molds, mechanical sliding parts, advanced coil coatings for food, textile, papermaking and other industrial machinery, various tanks, pipelines, pumps, reactors, heat exchangers and precision instruments And other coating and lin...
