High-transmittance high-heat insulation energy-saving explosion-proof membrane and preparation process thereof

Abstract

The invention discloses a high-transmittance high-heat insulation energy-saving explosion-proof membrane and a preparation process thereof. The membrane comprises a substrate layer, wherein a first metal indium layer is magnetron-sputtered on one surface of the substrate layer; a metal silver layer or a metal aluminum layer as a heat insulation layer is magnetron-sputtered the other surface of the first metal indium layer; a second metal indium layer is magnetron-sputtered on the other surface of the metal silver layer or the metal aluminum layer; and the preparation process comprises the following steps: preparing a plastic-based membrane; magnetron-sputtering and depositing the first metal indium layer for oxidation protection on the plastic-based membrane in the step one; magnetron-sputtering and depositing the heat insulation layer on the other surface of the first metal indium layer; and magnetron-sputtering and depositing the second metal indium layer on the other surface of the heat insulation layer in the step three. According to the invention, the high-transmittance high-heat insulation energy-saving explosion-proof membrane is beneficial to reflecting and blocking infrared rays in solar rays and significant in heat insulation effect, and can preferably protect the magnetron-sputtered metal layers, prevent the metals from oxidation, and improve and ensure the performance and service life of products, thereby being applicable to places with higher requirements; and meanwhile, the invention provides the preparation process of the above high-transmittance high-heat insulation energy-saving explosion-proof membrane.

Description

technical field [0001] The invention relates to a high-permeability, high-heat-insulation, energy-saving and explosion-proof membrane and a preparation process thereof, belonging to the technical field of adhesive materials. Background technique [0002] It has been more than 30 years since magnetron sputtering coated glass entered the domestic architectural glass market in the 1980s. More than 40 coated glass production lines have been introduced in China, and several small continuous production lines have been independently designed and manufactured. There are many scientific research institutes, manufacturers of coated glass equipment, and technicians on the front line of coated glass production, who are constantly conducting research on the process, technology, control, etc. of coated glass production from different levels, different angles, and different needs. and explore. [0003] The process principle of magnetron sputtering is in a vacuum chamber filled with a sma...

Problems solved by technology

[0005] At present, the glass used in buildings and general places and the glass used in automobile bodies are generally pure glass. Although pure glass has good light transmittance, it is convenient for observing the external situation and for the driver to observe the road traffic conditions and the occupants in the car. Observe the situation outside the car, on the one hand, but the sunlight and other light outside the glass often affect the eyes and vision of the people inside the glass and the driver of the car; on the other hand, the sunlight outside the glass will heat the inside of the glass and Inside the car, the temperature of the inner surface of the glass and the interior of the car is increased. What is more serious is that when the glass is broken due to an accident, the broken glass will fly and hurt the surrounding people. Therefore, curtains are often installed behind the glass and inside the car to block the sun. and heat insulation, the method of sticking plastic film is currently used, but those skilled in the art have not paid enough attention to the heat insulation performance
