Problems solved by technology

[0002] With the rapid development of the economy, the penetration rate of cars is getting higher and higher. In order to improve the privacy of the car, car film is usually attached to the inside of the window glass. With the sunlight and the passage of time, the car film is prone to aging. , and because the vast majority of automotive interior parts are made of plastic or leather, when exposed to the sun for a long time, the automotive interior will age seriously and even affect normal use. Therefore, it is necessary to design an automotive dimming glass and its preparation method. Use the power on and off to realize the random switching between the transparent and atomized state of the glass, reduce the transmittance of sunlight, and at the same time, use the preparation method of the present invention to ensure that the produced automobile glass has better privacy and superiority. Excellent impact resistance, while effectively blocking the damage of ultraviolet rays to the human body

Embodiment Construction

[0024] In order to facilitate the understanding of the present invention, the following will be described in conjunction with the accompanying drawings and embodiments.

[0025] refer to figure 1 It can be seen that the present invention discloses a method for preparing automotive dimming glass, comprising the following steps:

[0026] Step 101: preparing a conductive layer to provide a transparent organic film, the transparent organic film is less than 10 3 Under the ultra-low pressure environment of Pa and the carbon source fed in at a temperature greater than 600 ° C, a graphene layer with a thickness of 20nm-400nm is formed by chemical vapor deposition, and an electrode is arranged at the end of the graphene layer;

[0027] Step 102: Prepare the dimming film 3, prepare graphite nanoparticles through an ultrafine pulverizer, mix graphite nanoparticles, smectic liquid crystal materials, polymerizable monomers and initiators and stir to form a mixture, the mixture includes m...

Abstract

The invention provides automobile smart glass and a manufacture method thereof. The manufacture method comprises steps of preparing a conductive layer, wherein a transparent organic film and an introduced carbon source are prepared into a graphene layer through chemical vapor deposition at over 600DEG C in a less than 103Pa environment; preparing a smart film, wherein graphite nano particles, a smectic liquid crystal material, a polymerizable monomer and an initiator are mixed and blended uniformly, then a mixture is sprayed or etched at the side of the graphene layer in the conductive layer,and then is radiated by 400nm ultraviolet light for 10-30 minutes at 20-70DEG C so as to be cured to form the smart film; providing a first conductive layer and a second conductive layer, on which thesmart film is cured, bonding or laminating the first conductive layer onto the second conductive layer; and providing two glass layers, bonding or laminating the two glass layers on opposite sides ofthe first conductive layer and the second conductive layer respectively, and sealing the edge. Automobile smart glass prepared by the manufacture method can well protect privacy of users, and has high shock resistance and soundproof effect.
