Description
Technical Field
The invention belongs to the technical field of plastic processing, and particularly relates to a scratch-resistant heat-resistant film and a preparation method thereof.
Background
The scratch-resistant heat-resistant film is a functional film which is directly pasted and is processed by a precise coating process after ink is prepared by using PET subjected to surface hardening treatment as a base material and nano multi-element doped oxide with excellent heat-insulating property as a medium and by using a unique dispersion technology.
The nano ceramic particles can absorb near infrared rays and far infrared rays strongly, but have high transmittance for visible light, infrared rays are converted into heat energy, and the heat transfer coefficient of the glass (1) is far greater than that of outdoor air of PET (2), so that the glass is convective, and heat dissipation is facilitated. Therefore, most of the heat absorbing the infrared is diffused to the outdoor, and only a small amount of heat (less than 10 percent) is radiated to the indoor by the far infrared rays, thereby reducing the indoor temperature by 5 to 8 ℃.
As a window film protection product, the scratch-resistant heat-resistant film also has the advantages of buffering impact, preventing glass from bursting, or preventing glass from being broken and scattered due to careless impact, reducing hidden damage of glass, ensuring user safety, and simultaneously keeping the unique luster of the glass on the screen surface and the softness and texture close to natural blue in the sky and improving the surface hardness.
