As shown in fig. 1 and 2, the present embodiment provides a laminated heat insulating glass for a cab, which includes an outer layer glass 1, an inner layer glass 2, and a heat insulating film 3. Wherein, outer glass 1 is located the outside of driver's cabin, and outer glass 1 is prepared by the green glass of F. The inner layer glass 2 is positioned on the inner side of the cab, and the inner layer glass 2 is made of colorless transparent glass. The heat insulation film 3 is clamped between the outer layer glass 1 and the inner layer glass 2, the heat insulation film 3 is respectively bonded with the outer layer glass 1 and the inner layer glass 2, and the heat insulation film 3 is prepared from a heat insulation PVB film.
In order to cover the black glue used for bonding and maintain the aesthetic appearance, a glass black tape 11 is optionally arranged on the inner layer glass 2. In order to facilitate installation and positioning, a transparent positioning mark 12 is optionally arranged on the glass black belt 11.
In order to improve the heat insulation performance of the heat insulation PVB film, optionally, indium tin oxide nanoparticles are added to the heat insulation PVB film. In order to further improve the heat insulation performance of the heat insulation PVB film, antimony tin oxide nanoparticles are optionally added to the heat insulation PVB film.
To ensure the transparency of the outer glass 1, the outer glass 1 is optionally 3mm thick. To ensure the transparency of the inner glass 2, the inner glass 2 is optionally 3mm thick. To ensure the heat insulating performance of the heat insulating film 3, the thickness of the heat insulating film 3 is optionally 0.76 mm. In order to buffer the wind pressure in front of the vehicle, optionally, the outer glass 1 and the inner glass 2 are both curved.
The laminated heat-insulating glass for the cab provided by the embodiment is roughly processed as follows:
cutting a large sheet, and cutting the original sheet glass into a blank, wherein the blank glass is 30-50mm larger than the actual specification so as to facilitate the edge breaking at the periphery. When the blank is cut, the glass showering direction needs to be noticed, and the two pieces of glass are in the vertical showering direction, so that the visual distortion of a driver is low, and the driver is not easy to fatigue.
And step two, cutting, namely cutting the outer glass sheet and the inner glass sheet according to the curvature and the spherical surface size of the glass.
And step three, edging, namely edging the edge of the glass according to requirements, removing the quick opening without cutting hands, and finely edging the exposed edge of the glass.
And step four, washing and drying to eliminate dust, oil stains and impurities on the surface of the glass and ensure the best adhesive force.
And fifthly, spraying powder, wherein in order to prevent the two glass laminated layers from being stuck in the baking and bending process, a thin layer of powder is usually sprayed on the surface of the glass, and silicon dioxide with the diameter of 0.8 micron is usually used.
And sixthly, bending by baking, namely, performing hot bending by using a bending die into various shapes and annealing to form a laminated glass semi-finished product, wherein the hot bending is generally performed in a bending furnace, the bending furnace is generally divided into an upper layer and a lower layer, the upper layer is used for preheating and bending forming, the lower layer is used for annealing and cooling, and a die is removed.
And step seven, cleaning powder, namely cleaning the powder sprayed on two sides of the glass when the glass and the heat-insulating PVB film are laminated, wherein the powder comprises the edge part of the glass, and the glass is ensured not to generate bubbles and pockmarked glass.
And step eight, drawing the heat-insulating PVB film, uniformly heating the heat-insulating PVB film, stretching the heat-insulating PVB film into a fan shape, and uniformly cooling to freeze the bent shape of the heat-insulating PVB film into a permanent bent shape.
And step nine, humidifying, wherein the water content of the heat-insulating PVB film has great influence on the performance of the laminated glass, the higher the water content is, the smaller the adhesive force between the heat-insulating PVB film and the glass is, and conversely, the lower the water content is, the stronger the adhesive force is, and the smaller the penetration resistance is.
And step ten, laminating, namely putting the glass needing to be clamped with the heat-insulating PVB film on a laminating machine, sucking up the upper sheet by using a vacuum chuck, putting the heat-insulating PVB film, putting down the upper sheet of glass, and cutting off redundant leftover materials of the heat-insulating PVB film.
And step eleven, performing primary pressing, namely exhausting air from a position between the glass in the sandwich shape and the heat insulation PVB film as much as possible by adopting a compression roller mode or a pressure reduction mode, and sealing the periphery so as to prevent hot kerosene or air bubbles from being immersed into the glass in a high-pressure process.
And step twelve, high pressure, wherein because the glass lamination is basically glued after initial pressing, a part of gas still cannot be removed at the initial pressing temperature, the gluing firmness is not strong, and in order to completely discharge and firmly glue bubbles in the lamination, larger uniform pressure and higher temperature required for softening the film are applied, so that the film is heated and pressurized in an autoclave, and the gas is completely discharged, and the glass and the heat-insulating PVB film are completely glued and are transparent.
In the production process, a single-layer heat-insulating PVB film is adopted, the processing process is the same as that of common laminated glass, the production process difficulty is not increased, and the yield is high. Because the thickness of the glass is not increased by the single-layer heat-insulating PVB film, the transportation and storage management of the glass cannot be influenced. And simple structure possesses good thermal-insulated function simultaneously, and the practicality is high, can obtain extensive application.
The laminated heat-insulating glass for the cab can effectively block infrared rays in sunlight, compared with common laminated glass, the direct sunlight transmittance can be reduced by about 23%, the total solar transmittance can be reduced by about 28%, the heat-insulating performance is greatly improved, the temperature in the cab can be reduced, and the working pressure of an air conditioner is reduced to the maximum extent, so that the fuel efficiency is improved.
As shown in fig. 3, the present embodiment further provides a cab assembly for a commercial vehicle, which includes the above-mentioned laminated insulating glass for a cab, and further includes a cab front windshield frame 4, wherein the laminated insulating glass for a cab is mounted on the cab front windshield frame 4. The commercial vehicle cab assembly provided by the embodiment can effectively block infrared rays in sunlight, compared with common laminated glass, the direct sunlight transmittance can be reduced by about 23%, the total solar transmittance can be reduced by about 28%, the heat insulation performance is greatly improved, the temperature in the cab can be reduced, the working pressure of an air conditioner is reduced to the maximum extent, the fuel efficiency is improved, compared with coated glass, the cost is reduced, the visible light transmittance can still reach more than 80% while heat is effectively blocked, the requirement on the transmittance of automobile glass is met, and the driving safety is improved.
