Nanophase ceramic heat-insulation window membrane

Abstract

The invention discloses a nanophase ceramic heat-insulation window membrane which is of a composite structure. The nanophase ceramic heat-insulation window membrane comprises a wear-resistant layer (1), a base membrane layer (2), a nanophase ceramic heat-insulation adhesive layer (3), a function membrane layer (4), a pressure sensitive adhesive layer (5) and a protection membrane layer (6), and the layers are composited into a whole; the wear-resistant layer (1) is combined on one surface of the base membrane layer (2) through ultraviolet light polymerization; the nanophase ceramic heat-insulation adhesive layer (3) is combined on the other surface of the base membrane layer (2) through thermocuring; one surface of the function membrane layer (4) is composited on the outer surface of the nanophase ceramic heat-insulation adhesive layer (3); the pressure sensitive adhesive layer (5) is combined on the other surface of the function membrane layer (4) through thermocuring; the protection membrane layer (6) is composited on the outer surface of the function membrane layer (4). The layers produce a synergistic effect, infrared rays can be selectively blocked, the thermal radiation of sun is blocked in summer to reduce the energy consumption of refrigeration of an air conditioner, and the loss of internal heat is blocked in winter to lower the heating cost, so that the nanophase ceramic heat-insulation window membrane has a green energy-saving effect.

Description

technical field [0001] The invention specifically relates to a nano-ceramic thermal insulation window film, which is particularly suitable for pasting on the glass surface of buildings or automobiles. Background technique [0002] With the continuous improvement of society's requirements for energy saving and environmental protection, people put forward higher heat insulation requirements for places requiring good lighting such as buildings and cars. Since ordinary glass is not selective for the transmission of sunlight, a large amount of heat in the infrared region of the solar spectrum will also be transmitted while sufficient visible light is transmitted, resulting in an increase in indoor temperature and increased air conditioning, etc. load, resulting in a waste of energy. Aiming at the energy loss of door and window glass, etc., people have invented low-e glass and glass heat-insulating window film. These methods are all to isolate solar heat radiation and reduce temp...

AI Technical Summary

Problems solved by technology

Nano-ceramic heat-insulating film has attracted much attention because of its good light transmittance and infrared blocking rate. However, the nano-ceramic heat-insulating film currently on the market has a low heat-insulating rate, or it has a high heat-insulating rate. The transmittance is relatively low, which affects lighting, and the product has a large apparent haze, which is easy to fade or has poor weather resistance for heat insulation
