Problems solved by technology

[0003] At present, several types of infrared absorbing films have been studied: the first is metal films, such as silver and copper films, which can shield part of visible and infrared light. This type of film is mainly obtained by vacuum thermal evaporation or magnetron sputtering. However, this method is expensive and not conducive to large-scale preparation; the second is nanomaterial thin films, which are mainly prepared by solution methods, such as noble metal nanomaterials (silver / gold nanoparticles), rare earth element nano Materials and metal oxide semiconductor nanomaterials (ITO, AZO), but these materials can only absorb at a specific wavelength, or can only absorb infrared light greater than 1500 nanometers
The third is the tungsten-based nanomaterials that have been studied more and have better effects, but these materials are more expensive and these films containing heavy metals will pollute the environment, which is not conducive to popularization and application.

Embodiment 1

[0030] Weigh 1.2347gFeCl 3 ·6H 2 O and 1.5 g of polypropylene alcohol (PVA) were then added to 50 mL of deionized water, and stirred at room temperature for 1 hour to form a light yellow solution. Then, at 5°C, 140 μL of pyrrole monomer was added and reacted under stirring for 4 hours. After the reaction, centrifuged to obtain polypyrrole nanoparticles, the morphology is as follows figure 1 as shown, figure 1 a is a scanning electron microscope picture of polypyrrole, from which it can be seen that it is uniform spherical nanoparticles with uniform size (about 50nm); the transmission electron microscope picture in 1b further confirms that the prepared polypyrrole of the present invention is a uniform size ( 50nm or so) distributed spherical particles.

[0031] exist figure 2 In a, mix the polypyrrole powder prepared by the present invention with potassium bromide to make tablets, and test the infrared diagram. It can be seen from several characteristic absorption peak...

Abstract

The invention relates to an application of a macromolecule-based infrared absorption material to preparation of a full-macromolecule heat-insulating film. The macromolecule-based infrared absorption material and a macromolecule film-forming material are mixed and coat a carrier, and a film is formed after drying. The macromolecule nano material shows very high infrared light absorption capacity and has good visible light permeability after being mixed with the macromolecule film-forming material to form the film and has infrared and ultraviolet light shielding performance, the film cost is much lower than those when traditional magnetron sputtering and vacuum hot drying film-forming methods are used, meanwhile, the cost is lower than those of metal-based film materials, the secondary pollution problem caused by some metals is solved, and the material has enormous application value in preparation of full-macromolecule heat-insulating film materials.

Description

technical field [0001] The invention belongs to the application field of polymer-based materials, and in particular relates to the application of a polymer-based infrared absorbing material in the preparation of a full-polymer heat-insulating film. Background technique [0002] With the world's increasing energy consumption, the reduction of reserves, and the emergence of environmental pollution in the process of energy use, people are paying more and more attention to how to reduce energy consumption in life. As we all know, infrared light energy accounts for about 50% of the total energy of sunlight, and is the main source of heat generation. To a certain extent, it will bring a lot of discomfort to people's lives. Adjust the temperature. At present, the vigorous development of the automobile industry has increased the use of automobile air conditioners, which will greatly increase energy consumption and remove polluting gases. For this phenomenon, some optical materials...
