Abstract

The invention belongs to the technical field of insulation films and particularly relates to a single silver insulation film based on a dielectric layer. The single silver insulation film based on the dielectric layer is characterized in that a PET substrate is sequentially plated with a dielectric layer, a silver layer, a protective layer and a dielectric layer, the PET substrate is a poly ethylene terephthalate substrate with the thickness of 23-36 mu m, the dielectric layer is made of titanium dioxide with the thickness of 20-40 nm, the silver layer is made of silver with the thickness of 10-15 nm, the protective layer is made of titanium with the thickness of 1-4 nm, and the dielectric layer is made of the titanium dioxide with the thickness of 20-40 nm. The insulation film has the advantages of strong infrared ray reflective power, i.e. insulating capacity, high visible light transmittance, low reflectivity, neutral coloring of colors, natural and soft appearance effect and the like, and is particularly suitable for a vehicle foreside windscreen and the like having high transmittance requirement.

Description

technical field

[0001] The invention relates to the technical field of heat-insulating films, in particular to a single-silver heat-insulating film based on a dielectric layer. Background technique

[0002] Glass heat insulation usually adopts methods such as glass coating or filming, and heat insulation film has excellent comprehensive performance and is widely used. The existing heat insulation film generally has the contradiction of high heat insulation and high reflection of visible light. attached figure 1 It is the transmittance curve of a certain brand of heat insulation film measured by a spectrophotometer. It can be seen that the infrared transmittance is higher than the visible light transmittance, that is, there is a contradiction between high visible light transmittance and high heat insulation. Contents of the invention

[0003] The purpose of the present invention is to provide a single silver heat insulation film based on a dielectric layer with good heat ...
