Abstract

The invention relates to the technical field of thermal insulation materials, in particular to an infrared adjustment intelligent thermal insulation EVA film and a preparation method thereof. Modified powder with vanadium dioxide vanadium dioxide being a base body is doped with a proper quantity of other metal elements, a proper number of other additives are used in cooperation, the phase transition temperature of vanadium dioxide in the prepared EVA film is lowered to 36 DEG C or lower, reversible mutation happens to optical transmission performance in an infrared light area, and therefore the near infrared ray transmittance of the EVA film can be intelligently adjusted. When the temperature is higher than 36 DEG C, the infrared blocking rate is controlled to be 90% or higher; when the temperature is lower than 36 DEG C, the infrared blocking rate is controlled to be 50% or lower; meanwhile, it is guaranteed that the visible light transmittance is high, the light reflectance is low, and the phenomenon that traditional LOW-E glass is prone to light pollution does not exist. The EVA film prepared through the preparation method is used for manufacturing EVA interlayer glass and is applied to glass curtain walls or windows, the purpose that the environment is warm in winter and cool in summer can be achieved better, and the infrared adjustment intelligent thermal insulation EVA film is particularly suitable for the northern area in China.

Description

technical field [0001] The invention relates to the technical field of heat-insulating materials, in particular to an infrared-adjustable intelligent heat-insulating EVA adhesive film and a preparation method thereof. Background technique [0002] In the 21st century, with the depletion of energy and the deterioration of the environment, the governments of various countries have higher and higher requirements for energy conservation and emission reduction, and people urgently need more energy-saving and environmentally friendly green products. At present, Low-e laminated glass (such as EVA laminated glass) is the most used to make curtain walls or doors and windows. Although it has the effect of warming in winter and cooling in summer, it still has the defects of light pollution and low service life. [0003] In addition, it is known that under low temperature conditions, vanadium dioxide films have high transmittance in visible light, infrared light, radio frequency bands a...
