Abstract
The utility model discloses bulletproof glass for cars. The bulletproof glass comprises a surface layer, an interlayer and an inner layer from outside to inside in sequence, wherein the surface layer and the inner layer are white glass layers; the interlayer is a PVB (polyvinyl butyral) film; the surface layer and the interlayer are adhered by a first polyurethane (PU) layer; the inner layer and the interlayer are adhered by a second PU layer; and the thickness of the surface layer is 2.5-2.8 times that of the interlayer. The bulletproof glass is convenient to process, can be produced in any area, is high in safety, can resist shooting with F79 charging power and knocking of 8-pound hammers, can be never punctured even if the surface of the glass has cracks or is ruptured, is light in weight and is suitable to be used together with cars.
Description
Technical field
The utility model relates to the glass manufacturing area with bulletproof function, especially relates to a bulletproof glass for automobile.
Background technology
Traditional bulletproof glass is because volume is large, the heavy gate that often only is adapted to financial sector of deal, the scope of application is little, present bulletproof glass structure is commonly compound glass and one deck carbonic ester plate utilizes polyvinyl butyral film and polyurethane pellicle to be composited, and be characterized in that bulletproof effect is good, but quality lays particular stress on, cost is high, can increase the weight of vehicle weight, increase automobile fuel consumption, not be suitable for automobile and use.
The utility model content
The utility model is in order to overcome the deficiencies in the prior art, provide a kind of easy to process, bulletproof effect good, lightweight bulletproof glass for automobile.
To achieve these goals, the utility model by the following technical solutions: a kind of bulletproof glass for automobile, comprise successively from outside to inside top layer, interlayer and internal layer, described top layer and internal layer are the white glass layer, described interlayer is the PVB film; Bonding by the first layer of polyurethane between top layer and the interlayer, bonding by the second layer of polyurethane between internal layer and the interlayer; The thickness on described top layer is 2.5-2.8 times of thickness of interlayer.
Further, the thickness of described the first layer of polyurethane be the second layer of polyurethane thickness 1.1-1.2 doubly.
Further, the thickness on the thickness of described internal layer and top layer is 5mm.
Further, the thickness of described the first layer of polyurethane is 1.35mm, and the thickness of the second layer of polyurethane is 1.15mm.
In sum, the utlity model has following advantage: the utility model is easy to process, and size all can be produced; Security performance is high, can support pre-F79 the charge shooting of power and beaing of 8 pounds of hammers, even glass surface causes slight crack or splits, but effect that will not be breakdown; Lightweight, be fit to use with automobile.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is carried out clear, complete description.
As shown in Figure 1, a kind of bulletproof glass for automobile comprises top layer 1, interlayer 2 and internal layer 3 from outside to inside successively, and described top layer 1 and internal layer 3 are the white glass layer, and described interlayer 2 is the PVB film; Bonding by the first layer of polyurethane 4 between top layer 1 and the interlayer 2, bonding by the second layer of polyurethane 5 between internal layer and the interlayer; The thickness on described top layer is 2.5-2.8 times of thickness of interlayer.
Further, the thickness of described the first layer of polyurethane be the second layer of polyurethane thickness 1.1-1.2 doubly
As preferably, the thickness of described internal layer and the thickness on top layer are 5mm.
The thickness of described the first layer of polyurethane is 1.35mm, and the thickness of the second layer of polyurethane is 1.15mm.
Obviously, described embodiment only is a part of embodiment of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all should belong to the scope of the utility model protection.
