Abstract
The utility model aims to provide a bulletproof glass for automobiles, which has good bulletproof capability and light specific weight. The bulletproof glass for the automobiles of the utility model is characterized by comprising a surface layer of glass, an interlayer of polymethylmethacrylate plate and a back layer of polycarbonate plate, wherein the surface layer of glass is bonded with the polymethylmethacrylate plate through a polyvinyl butyral film, and the polymethylmethacrylate plate is bonded with the polycarbonate plate through a polyurethane film. The bulletproof glass for the automobiles of the utility model utilizes the polymethylmethacrylate plate to substitute the interlayer of glass in the traditional bulletproof glass, and thereby ensuring the bullet resistance and simultaneously relieving the integral weight, the utility model is beneficial to reliving the whole weight of automobiles when being applied on the automobiles, and thereby reducing the oil consumption.
Description
Technical field
The utility model belongs to the Manufacturing Technology for Automotive Parts field, specially refers to the bulletproof glass of automobile.
Background technology
The structure of bulletproof glass mainly contains two kinds at present: first kind is that compound glass and polyvinyl butyral film are composited, and be characterized in that cost is low, but bulletproof effect is poor; Second kind is utilized polyvinyl butyral film and polyurethane film to be composited the compound glass and one deck carbonic ester plate, is characterized in that bullet-proof is good, but quality lays particular stress on, and can increase the weight of vehicle weight, increases automobile fuel consumption.All there is certain drawback in above-mentioned two kinds of bulletproof glasses, are unsuitable for using on the automobile.
The utility model content
The purpose of this utility model is that a kind of ballistic performance of proposition is good, the automobile bulletproof glass of light specific gravity.
Automobile of the present utility model is to comprise skin glass, intermediate layer polymethyl methacrylate plate and backing layer polycarbonate plate with the key of bulletproof glass, be bonding between skin glass and the polymethyl methacrylate plate wherein by polyvinyl butyral film, bonding between polymethyl methacrylate plate and the polycarbonate plate by the polyurethane film.
The polymethyl methacrylate plate has excellent light transmission, higher draw tensile strength and bending strength, the utility model replaces intermediate layer glass in traditional bulletproof glass with the polymethyl methacrylate plate, both can weight reduction can also effectively resist impact, guarantee ballistic performance, and the polymethyl methacrylate plate is difficult for brokenly than glass, is placed on the fragment that the middle level produces when can barrier surface layer glass broken, prevents that it from hurting the occupant.
Polycarbonate plate has the characteristics of high strength, high resiliency and high tenacity, by plastic deformation, the bullet kinetic energy full consumption of slowing down can be fallen, and guarantee not penetrate or break passenger's safety in the car that adequately protects.
Above-mentioned skin glass is preferably safety glass, and its strength ratio simple glass improves several times, and bending strength is 3～5 times of simple glass, and impact strength is 5～10 times of simple glasses, the security that can improve bulletproof glass greatly.
The thickness of described skin glass is 3.5 ± 0.35mm, the thickness of polyvinyl butyral film is 0.76 ± 0.076mm, the thickness of intermediate layer polymethyl methacrylate plate is 5 ± 0.5mm, and the thickness of polyurethane film is 1.25 ± 0.125mm, and the thickness of backing layer polycarbonate plate is 3 ± 0.3mm.
Automobile of the present utility model utilizes the polymethyl methacrylate plate to replace intermediate layer glass in traditional bulletproof glass with bulletproof glass, when guaranteeing ballistic performance, alleviate overall weight, helped alleviating the automobile overall weight when being applied on the automobile, thereby reduced oil consumption.
Description of drawings
Fig. 1 is the structural representation of automobile of the present utility model with bulletproof glass.
The specific embodiment
Describe the utility model in detail below in conjunction with specific embodiments and the drawings.
Embodiment 1:
As shown in Figure 1, the automobile of present embodiment comprises top layer safety glass 1, intermediate layer polymethyl methacrylate plate 3 and backing layer polycarbonate plate 5 with bulletproof glass, wherein bonding between safety glass 1 and the polymethyl methacrylate plate 3 by polyvinyl butyral film 2 HTHPs, bonding between polymethyl methacrylate plate 3 and the polycarbonate plate 5 by polyurethane film 4 HTHPs.
The thickness of described skin glass is 3.5mm, and the thickness of polyvinyl butyral film is 0.76mm, and the thickness of intermediate layer polymethyl methacrylate plate is 5mm, and the thickness of polyurethane film is 1.25mm, and the thickness of backing layer polycarbonate plate is 3mm.
