The origin, development and process history of heat insulation auto window tint film:


Heat insulation auto window tint film is becoming more and more life-oriented. For car owners, heat insulation auto window tint film not only enhances privacy, but also blocks direct sunlight, which has the effect of heat insulation and is full of practicability. But do you know the history of insulation auto window tint film? Do you know that the origin of insulation auto window tint film is still related to Edison!


The origin of insulation auto window tint film



After Edison invented the phonograph in 1888, he turned his attention to developing movies. In his research, he found that the darker the film, the better it can block and absorb the heat emitted by the lamp. Therefore, this accidental discovery was gradually adopted by later generations, and became the basis and origin of the birth of heat insulation auto window tint film.


The development of insulation auto window tint film :


With the continuous progress of history, insulation auto window tint film has gone through 5 periods (or "five generations"):


The first generation: Sun paper (tea paper)


Time: 1930;


Positioning: Heat insulation auto window tint film enters the market;


Process: The coating composite process is used;


Features: It is used to block strong sunlight and does not have heat insulation function;


Introduction: The early solar paper, commonly known as tea paper, is mainly used to block strong sunlight. This type of film has basically no heat insulation effect, and is only used for shading. Like sunglasses, it only changes the visual light perception, and the surface of the sunglasses is also very hot. Therefore, such products have poor heat insulation, are easy to fade, and have extremely poor clarity. With the improvement of people's requirements for heat insulation, tea paper has gradually faded out of the market.


The second generation: heat absorbing film (dyed auto window tint film)


Time: 1960;


Positioning: Heat insulation auto window tint film came into being;


Process: the dyeing process is used;


Features: Absorbing infrared rays to achieve heat insulation effect, sacrificing clarity (poor clarity), easy to fade (color fades, heat insulation function attenuation);


Introduction: The heat-absorbing film is also called dyed window tint film. Most of the products in the market are deep-layer dyeing process. The heat-absorbing agent is added by the deep-layer dyeing method to absorb the infrared rays in the sun to achieve the effect of heat insulation. Because it also absorbs visible light at the same time, the visible light transmittance is not enough, coupled with the limitation of the dyeing process itself, the clarity is poor. In addition to poor clarity, another major weakness of this type of auto window tint film is that the thermal insulation function decays quickly and is easy to fade. After a period of time (maybe half a year or a year), the auto window tint film will fade, no longer insulate, and will foam, seriously affecting the visual perception. This type of auto window tint film is particularly suitable for instantaneous thermal insulation tests. The color can be observed directly with the naked eye.


On December 6, 1966, 3M Corporation of the United States obtained the world's first patent on solar insulation auto window tint film.


The third generation: metal auto window tint film


Time: early 1990s;


Positioning: thermal insulation auto window tint film is booming;


Process: vacuum thermal evaporation process;


Features: Add a metal layer on the auto window tint film, use reflection to achieve heat insulation effect, the definition is not high, easy to reflect light.
