As shown in fig. 1 and fig. 2, the heating defrosting defogging bulletproof glass for a vehicle has a first surface (not shown) and a second surface (not shown) corresponding to the first surface, the first surface is a concave surface, the second surface is a convex surface, the heating defrosting defogging bulletproof glass for a vehicle has seven layers, and a first glass layer 2, a PVB functional membrane 4, a PVB membrane 5, a second glass layer 3, a first bulletproof membrane 6, a second bulletproof membrane 7 and a third glass layer 1 are sequentially arranged from the concave surface to the convex surface.

In order to enable the automobile tungsten filament heating defrosting demisting bulletproof glass to have a heating function, 2 groups of wave-shaped tungsten filaments 11 are arranged in the PVB functional membrane 4, copper foils wrap the peripheral edge of the PVB functional membrane 4, and the 2 groups of wave-shaped tungsten filaments 11 are connected in parallel with the copper foils to form 2 parallel closed loops.

The bulletproof film needs to have strong toughness and is used as a transition layer of bulletproof glass, so that flying bullets firstly hit a brittle layer (glass), most of kinetic energy is absorbed, and then the bullets are intercepted by the toughness layer; and the front and rear interlayers can still be bonded together without falling off after being crushed, so that the first bulletproof film 6 is added with polycarbonate fibers, and the second bulletproof film 7 is added with polyvinyl butyral.
The above-mentioned parts for heating, defrosting, demisting and bulletproof glass of the tungsten filament for the vehicle include, but are not limited to, the above-mentioned types.
The method for manufacturing the tungsten filament heating defrosting demisting bulletproof glass for the vehicle is described as follows:
pretreatment: 1. firstly, accurately cutting 3 layers of required flat plate samples of glass on 8mm and 6mm original sheets of glass on an automatic cutting machine according to the size and shape after the original sheets of glass are unfolded; 2. edging: and edging the cut flat plate sample on a belt edge grinding machine. The sharp edges are ground, so that microcracks on the edge part flowing down when the edges are cut and broken in the previous process can be eliminated, and the fracture of the edge part in the subsequent hot bending process is avoided. Meanwhile, the sharp edges and corners are prevented from cutting operators. 3. Screen printing: the black edges, the flower dots and the relevant printing characteristics of the periphery of the printing glass are used as decoration or used for shielding the bus bars and joints of the subsequent functional membrane.
(II) hot bending: the whole baking and bending process is divided into several links of heating, forming, cooling and annealing and cooling. This link is to solve the following two problems: 1. the problem of thermal bending molding of the glass with the ultra-conventional thickness is solved. 2. The problem of the bending molding of multilayer glass and the guarantee of profile uniformity is solved. The common laminated glass has 2 layers with the thickness of 2mm +2mm, while the utility model has 3 layers with the thickness of 8mm +6mm +6 mm; the glass thickness difference is too much, and the glass forming difficulty is greatly increased. And different processes, equipment and tools are needed for completion. Because the thickness of the glass is larger and the number of layers of the glass is relatively increased, a special die is needed to be formed in a single-chamber furnace which can be controlled by a heating furnace wire in real time. The method comprises the steps of preheating a mold, carrying out scratch-proof treatment on a mold forming frame, sequentially stacking 3 layers of pretreated flat plate samples according to the sequence of a third glass layer 1(8mm), a second glass layer 3(6mm) and a first glass layer 2(6mm) into the mold forming frame, adjusting the distance between the periphery of the glass and the forming frame, and adjusting the relative distance between the 3 layers of glass so as to ensure that the stacking difference is uniform. And then entering a single-chamber furnace for bending. When the glass is gradually heated to the softening point of the glass, the space curved surface is gradually formed along the forming frame under the action of gravity, and at the moment, the height and the power of the upper and lower movable furnace wires are adjusted according to the forming state of the glass, so that the local molded surface with higher appearance requirement is heated and formed, and the full and smooth space molded surface is ensured.
And (III) an organic laminated adhesive sheet of the multilayer glass and the multilayer functional membrane formed by hot bending. The process is a crucial process for the functionality of the tungsten bulletproof glass. 1. Firstly, the glass after bending is cleaned, washed and cleaned. 2. And laminating the multilayer glass and the multilayer functional membrane. (1) The process is complex to implement and control and has high requirements on the environment. The whole process needs to be carried out in a dust-free room with the temperature of 18-25 ℃ and the relative humidity of 18-35%. (2) Firstly, a first glass layer 2 with the thickness of 6mm is conveyed to a laminating station with the convex surface facing upwards through a conveying line; (3) then a PVB functional membrane 4 with a thickness of 0.76mm and containing the wavy tungsten wires 11 is laid. The diaphragm is provided with 2 groups of wave-shaped tungsten filaments 11 in a parallel connection mode, wide and thin copper foils are arranged along the peripheral edges, and the shape and the size of each copper foil correspond to silver paste buses printed by glass; the 2 groups of parallel tungsten filaments form 2 parallel closed loops through the copper foils on the periphery. The whole laying process is smooth and uniform, the membrane cannot be folded, and the heating function of the tungsten filament is prevented from being influenced by the damage of the tungsten filament; (4) then a layer of common PVB film 5 is laid by the same method; then 2 sets of copper sheet joints 10 are pressed in at the bus bar joint between the two layers of membranes, and the direction of 2 sets of parallel joints is noted. (5) Then laying a second glass layer with the thickness of 6mm, wherein the concave surface of the second glass layer is matched with the convex surface of the front glass layer, so that the stacking difference is uniform, and the laid membrane cannot be dislocated during the laying process; (6) then, a first bulletproof film 6 and a second bulletproof film 7 with the thickness of 0.76mm are paved according to the previous method, and the two films are mostly polycarbonate fibers added with certain components and have strong toughness and are used as transition layers of bulletproof glass. The flying bullet firstly hits the brittle layer (glass), most of kinetic energy is absorbed, and then the flying bullet is intercepted by the toughness layer; and the front interlayer and the rear interlayer can still be bonded together after being crushed without falling off. (7) And finally, laying a third glass layer 1 with the thickness of 8mm, thus finishing the whole adhesive sheet clamping process.
And (IV) vacuumizing and pre-pressing: and (3) vacuumizing and prepressing the combination of each layer of glass and each layer of functional membrane after the lamination of the adhesive sheets in a vacuum furnace with the temperature of about 110 ℃ and the vacuum degree of (-0.08) -0.1) MPa, so as to remove most of air between each layer of glass and the PVB functional membrane through negative pressure.
(V) high-pressure vacuum pumping: putting the glass combination pre-pressed in the previous procedure into an autoclave, heating and pressurizing the whole body at a certain temperature and under a certain pressure through the autoclave, and removing the rest gas; and simultaneously, the functional films and the glass are organically bonded together. Wherein, the high-pressure process is gradually heated and pressurized in three stages to reach the balanced maintenance pressure of 1.2 MPa; the curing temperature is 140 ℃; curing for 30 minutes; then reducing the pressure and the temperature by sections, and finally rapidly cooling.
And (VI) respectively carrying out various comprehensive function tests. Thus, all the manufacturing processes of the utility model are completed.
