Abstract
The utility model discloses a bulletproof and theftproof door, the intermediate layer of which is cold rolled steel sheet keel layer. Both sides of the keel layer are polyurethane filling material layers, both sides of the filling material layers are aramid fiber board layers, and both sides of the aramid fiber board layers are solid wood boards, and the connections between the layers are fixed. The edge sealing of the door is made by cold rolled steel sheet, between the layers epoxy resin or vinyl-based resin is used for sticking. Said utility model may fully exerts the following advantages of the aramid fiber: high tensile strength, high elastic modulus, low density, good performance of absorption and shock damping, high resistance to wear, impact and fatigue, stable size, high resistance to chemical corrosion, high dielectric properties, high resistance to heat, and low expansion and heat conductivity, together with the resistance to melting and high resistance to cutting. By using this aramid fiber on the bullet-and-theft-proof door, the performance of traditional ones would be greatly improved.
Description
Technical field
The utility model relates to a kind of security door, especially a kind of shellproof security door.
Background technology
Current society, people are more and more stricter to safety, secret requirement.Relate to the place of state secret in bank, army, public security etc., perhaps hotel, villa, office building, and important transport facility such as aircraft, armoured van all will be installed high strength, be had the door of shellproof anti-theft feature.
But at present, domestic most shellproof security door still uses conventional methods, and in promptly being clipped in the steel plate of thickening, or adopts steel plate to manufacture fully.The door that adopts the method to manufacture, the increase of steel plate thickness must cause the increase of the quality of door, give construction, install and bring very big difficulty.And steel plate still has deficiency at anti-high-strength impact, aspect such as anticorrosive.
In order to change this situation, developed the shellproof security door of glass fiber, carbon fibre composite both at home and abroad, they have the feature of high strength, resistance to chemical attack, light weight, but the tensile strength of glass fiber compound material is enough not high, the fracture elongation of carbon fiber is low, and brittle fracture easily takes place.
Therefore people need a kind of new material make shellproof security door, this material require has the advantage that other traditional materials do not possess, as intensity, modulus of elasticity height, and good fire prevention, resistance to chemical attack, characteristic such as heat-resisting.
Summary of the invention
The technical problems to be solved in the utility model is to overcome traditional security door quality weight, shock resistance, corrosion resistance is poor, tensile strength is low, shortcomings such as brittle fracture easily take place.
In order to solve the problems of the technologies described above, the utility model provides a kind of shellproof security door that adopts the aramid fiber plate to manufacture, it is characterized in that: the intermediate layer is the cold-rolled steel sheet keel layer, the keel layer both sides are the polyurethane encapsulant layer, the encapsulant layer both sides are the aramid fiber flaggy, aramid fiber flaggy both sides are the solid wood plate, the layer with layer between fixedly connected.
As a kind of improvement of the present utility model, the edge sealing of door adopts cold-rolled steel sheet to carry out edge sealing.
As another kind of improvement the of the present utility model, adopt epoxy resin or vinylite to bond between every layer.
Adopt shellproof security door described in the utility model, can give full play to the following advantage of aramid fiber:
1, high tensile, high elastic modulus.
2, low-density, good energy absorption capacity and damping property.
3, wear-resisting, shock-resistant, antifatigue, dimensionally stable.
4, good chemical resistance.
5, superior dielectric properties, high heat-resisting, low bulk, low heat conduction, not molten.
6, high cutting opposing.
Be matrix, be the aramid fiber plate of reinforcement material with the aramid fiber with epoxy resin or vinylite, its tensile strength can reach 1300MPa, modulus of elasticity can reach 70GPa, fracture elongation is 2%, density is 1.4g/cm3, have excellent characteristics such as high strength, shock resistance, antifatigue, anti-cutting, corrosion-resistant, heat-resisting, light weight, use indeformablely for a long time, every performance does not reduce.This aramid fiber plate is applied on the shellproof security door, will improves the performance of traditional shellproof security door greatly.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Accompanying drawing is the sectional view of the shellproof security door of the utility model.
Among the figure, 1 is the solid wood plate, and 2 is the aramid fiber plate, and 3 is the polyurethane packing material, and 4 is the cold-rolled steel sheet keel, and 5 is compound door-plate, and 6 is the cold-rolled steel sheet edge sealing.
The specific embodiment
As shown in drawings, shellproof security door described in the utility model which floor sheet material of symmetry is made of.Wherein, innermost layer is a cold-rolled steel sheet keel layer 4, and it is trapezoidal waveform that this layer is pressed into waveform, can bear immense pressure.Cold-rolled steel sheet keel layer 4 both sides are polyurethane encapsulant layer 3, and this layer adapts with the shape of the contact surface of cold-rolled steel sheet keel layer 4 and the shape of cold-rolled steel sheet keel 4, also undulate; Another side is the plane.
More than adopt between each layer epoxy resin or vinylite to bond, after each layer bonding process finishes, began the bonding of one deck down after should condensing 1～2 day again.
After the board making of door is finished, should adopt cold-rolled steel sheet to carry out edge sealing, the usable resins bonding is carried out with the method that screw fixedly combines.
Claims (3)
1. shellproof security door that adopts the aramid fiber plate to manufacture, it is characterized in that: middle is the cold-rolled steel sheet keel layer, and the keel layer both sides are the polyurethane encapsulant layer, and the encapsulant layer both sides are the aramid fiber flaggy, aramid fiber flaggy both sides are the solid wood plate, the layer with layer between fixedly connected.
