Drawings
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention and not to limit the invention. In the drawings:
FIG. 1 is a block diagram of the present invention.
Detailed Description
Referring to fig. 1, the heat-insulating tempered glass for the automobile and the manufacturing method thereof comprise a 3-5 mm piece of body-colored tempered glass and a heat-insulating coating coated on the tempered glass, and are manufactured through wet coating and thermosetting processes. The mass-colored toughened glass can absorb 55-75% of solar infrared radiation and has selectable visible light transmittance; the heat insulation coating arranged on the toughened glass inner layer can absorb the residual solar infrared heat energy penetrating through the body-colored toughened glass, so that more than 96% of the solar infrared heat energy is blocked. The heat-insulating toughened glass coating contains nano heat-insulating particles capable of absorbing near infrared rays, such as nano compounds of cesium tungsten bronze and nano vanadium dioxide doped particles, so that the heat-insulating toughened glass coating has double functions of reflecting and absorbing infrared rays, and the nano vanadium dioxide doped particles can generate phase change at 40-50 ℃ and reflect solar infrared radiation; the nanometer heat-insulating particles absorb solar near-infrared radiation, simultaneously improve the temperature of the heat-insulating coating, promote phase change to occur, further improve the reflection efficiency of the nanometer vanadium dioxide doped particles on near infrared rays, and further improve the heat-insulating property of the glass as a result of combined action.
Organic or inorganic nano pigment for adjusting visible light transmittance is added into the heat insulation coating, and solar radiation heat energy is further reduced by reducing visible light transmittance. Visible light and infrared rays in sunlight respectively account for 50% of total solar radiation energy (the heat energy contained in ultraviolet rays is less than 5% and can be ignored), and the national standard of automobile safety glass only makes the requirement of more than 70% of light transmittance on the parts of an automobile front windshield and an automobile rearview mirror, and has no requirement on other parts of the automobile glass. Therefore, on the premise of maximum blocking of infrared transmission and meeting national standard requirements, the light transmittance of the visible light is properly transmitted, which contributes to further energy conservation. The ultraviolet absorbent contained in the heat insulation coating can reduce the ultraviolet transmittance to below 1 percent, protect organic or inorganic pigment from being degraded by ultraviolet rays and losing efficacy, and simultaneously avoid the injury of the ultraviolet rays to human skin and the damage to automobile seats, interiors and the like. The nanometer blue light absorbent contained in the heat insulation coating can reduce the transmittance of harmful blue light with the spectrum of 400-450 nm to below 10%, and can effectively protect eyes of people from being damaged. The nano organic or inorganic transparent pigment contained in the heat insulation coating has the colors of various commercially available materials and the visible light transmittance is selectable, such as green, gray, blue, tea, black and other colors, and can meet the personalized privacy requirements of customers. In addition, the thermochromic particles do not work at low temperature, solar radiation can be increased in winter, and energy conservation of new energy automobiles is facilitated.
