Problems solved by technology

The article "Research on Radiation Thermal Insulation Coatings" published in Journal of Changshu Institute of Technology (Natural Science Edition) 2007, 21 (4): 75-79 introduced in detail the process and method of their prepared radiation thermal insulation coatings. The reflectivity reaches 73.2%, but because the prepared thermal insulation coating is a water-based coating, it cannot be used on aluminum alloy profiles

Abstract

The invention discloses radiation type heat insulation powder paint for aluminum alloy sectional materials and a preparation method thereof. The paint comprises the following ingredients by mass parts: 100 parts of film forming agents, 4.0 to 10 parts of curing agents, 0.6 to 1.5 parts of flatting agents, 0.2 to 0.6 part of degasifying agents, 5 to 10 parts of infrared radiant materials and 40 to 60 parts of filling materials. The radiation type heat insulation powder paint for aluminum alloy sectional materials prepared by the invention can convert ultraviolet light, visible light and near infrared light in absorbed solar energy into heat energy, uses an infrared radiation mode for passing through an atmosphere infrared window in a wave band between 8 and 13.5 mum and for being efficiently emitted to the outer atmosphere layer, so the goal of reducing the temperature is reached. The radiation type heat insulation powder paint has the infrared heat reflecting rate of 65 percent, and in addition, the invention has the advantages of simple and convenient manufacture, low cost and wide application prospects.

Description

technical field [0001] The invention relates to a radiation-type heat-insulating powder coating for aluminum alloy profiles and a preparation method thereof. Background technique [0002] Building thermal insulation is an important aspect of saving energy and improving the living and use functions of buildings. Building thermal insulation coatings are more and more popular because of their economy, convenience in use and good thermal insulation effects. According to the different heat insulation mechanisms and methods of heat insulation coatings, they can be divided into three types: barrier heat insulation coatings, reflective heat insulation coatings and radiation heat insulation coatings. The first two types of heat insulation coatings can only slow down but not block The transfer of heat, while the radiative heat-insulating coating converts the absorbed ultraviolet light, visible light and near-infrared light energy into heat energy, and passes through the atmospheric in...
