Magnetic control heat-insulation anti-fog base film

Abstract

The invention discloses a magnetic control heat-insulation anti-fog base film. A metal and / or non-metal material can be sputtered on the outer surface of the magnetic control heat-insulation anti-fog base film through a vacuum magnetic control sputtering process. The magnetic control heat-insulation anti-fog base film sequentially comprises an anti-fog coating, a first hardened coating and a base material layer from inside to outside. The metal and / or non-metal material is sputtered on the outer side of the base material layer. The anti-fog coating comprises the following components: acrylic resin, a dimethyl silylated silica surfactant, an ethanolamine surface etchant, a polyquaternium surface active bactericide, water-insoluble carbonate, a melamine curing agent and a propylene glycol solvent. The anti-fog coating disclosed by the invention has a good anti-fog effect in a vehicle or in a room near zero DEG C in winter, water vapor generates an obvious infiltration effect on the surface of the coating and cannot be gathered into drops, and the anti-fog coating has good light transmission. No obvious performance degradation occurs in a long-acting test, and the waterproof and heat-insulating effects are good.

Description

technical field [0001] The invention relates to automobile glass film and architectural glass film, in particular to a magnetically controlled heat-insulating film, in particular to a magnetically controlled heat-insulating and anti-fog base film with an anti-fog function. Background technique [0002] Magnetron heat insulation film, also known as magnetron sputtering metal film, is made by multi-layer magnetron sputtering process, and is famous for its excellent performance of long-lasting reflective heat insulation. Because of its high definition, high heat insulation, high stability, low internal reflection, pure color, never fading, long service life and many other characteristics, it is widely used in automotive glass film and architectural glass film. [0003] The glass film produced by the vacuum magnetron sputtering process has a huge leap in terms of durable heat insulation performance, clarity, low reflection, and more natural metal primary colors. The magnetron s...

AI Technical Summary

Problems solved by technology

[0006] The existing magnetron heat insulation film has obvious advantages in heat insulation and color. However, when the temperature is low in winter, it is easy to fog due to the temperature difference between the inside and outside of the glass.

At present, the magnetic control heat insulation film on the market cannot avoid the fogging problem in the humid and cold environment, and there is a big safety hazard
