Abstract

The invention relates to a heat insulation super-weather-proof powder coating which comprises an epoxy resin particle system and a fluorocarbon resin particle system, wherein the epoxy resin particle system contains epoxy resin and a curing agent A, the fluorocarbon resin particle system contains fluorocarbon resin, a curing agent B and a heat insulation material. The ratio of parts by weight for the epoxy resin particle system and the fluorocarbon resin particle system is 6-4:4-6. The heat insulation super-weather-proof powder coating not only has good heat insulation, weather-proof and corrosion-resistant performance, but also can achieve self-layering after one-time coating, and is simple to construct.

Description

technical field [0001] The invention belongs to the field of functional powder coatings, in particular to a heat-insulating super-weather-resistant powder coating and its preparation method and application. Background technique [0002] The doors and windows made of aluminum alloy profiles are favored by people because of their good lighting, light weight, beautiful appearance, and high material reuse rate. At present, the amount of aluminum alloy doors and windows in the market accounts for 55% of the total amount of doors and windows, and has become the mainstream product in the door and window industry. However, the thermal conductivity of aluminum alloy profiles is as high as 203w / m·k, and the heat insulation effect of the aluminum alloy doors and windows produced is poor, resulting in high energy consumption of indoor air conditioners. [0003] Heat insulation coating is a functional coating with heat insulation effect, which can be used as a coating for aluminum alloy...
