Problems solved by technology
[0003] However, the above-mentioned transparent heat-shielding coating still has the following disadvantages: since it does not have an adjustment effect in the visible light band, this adjustment cannot be used to produce sufficient visual changes, which does not help to demonstrate a strong adjustment effect to customers. Propaganda and promotion cause decisive adverse effects
[0004] So far, there is no mature technology to fundamentally solve the above problems

Abstract
The invention relates to a temperature-controlled composite energy-saving material, which comprises: a visible light transparent infrared blocking inorganic material and an organic ligand conversion material that changes color in the visible light range. According to the present invention, the visible light transparent infrared blocking inorganic material is compounded with the organic ligand conversion material that changes color in the visible light range, so it has obvious visual changes compared with traditional heat insulation materials, and the large adjustment effect in the visible light band is transformed into visually The obvious change of the product has decisive significance for the effect display and promotion of the product.
Description
technical field [0001] The invention relates to the technical field of high-performance inorganic-organic composite materials, in particular to thermochromic heat-insulating materials and their energy-saving and environment-friendly applications. Background technique [0002] Modern buildings use a large number of thin and transparent external materials such as glass and plastic. While these materials improve indoor lighting, they inevitably cause sunlight to enter the room and cause indoor temperature to rise. In summer, in order to balance the rise in indoor temperature caused by sunlight, people generally use air conditioners to cool down. This is also the main reason for power cuts in some areas of our country in summer. Cars are becoming more and more popular, and the resulting summer reduces the temperature inside the car and reduces the energy consumption of air conditioners, making heat insulation film a standard configuration for cars. Others, such as the transpare...
