Problems solved by technology

For a long time, they have been made of traditional reinforced concrete protective airtight doors or multi-layer steel plates. Although they can play the role of fire prevention and anti-theft, and have high strength and strong bending and compression resistance, they have low production efficiency, heavy weight, The shortcomings of high transportation costs and inconvenient installation, due to the large structure of the protective door, it takes a lot of manpower and material resources, and the transportation process is cumbersome. Significant improvement to achieve light weight and protective airtight doors with ideal levels of waterproof performance, flame retardant performance, frost resistance performance, tensile strength, impact resistance, etc.

Abstract

The invention discloses a processing method for a lightweight protective door. The lightweight protective door is made of base materials and fillers through mixing, extrusion and high-temperature stamping. Dissolve and dilute, then send it into the mixing barrel for stirring and mixing evenly, lay a support film on the conveyor belt, and flow the diluted mixed base material into the distribution tank device from the bottom of the mixing barrel, so that the diluted mixed base material can be divided into The flow in the trough device is evenly divided and spread on the supporting film; the small section of filler formed by cutting the fiber cutting device above the conveyor belt is embedded in the diluted mixed base material, and the filled filler is extruded under the upper extrusion roller , so that the filler is fully embedded in the mixed base material on the surface of the supporting film, thereby forming a composite base material and sealing it, and then performing high-temperature stamping to form the required protective door model. The protective door of the invention has good comprehensive performance, high production efficiency, low processing cost and low transportation cost.

Description

technical field [0001] The invention belongs to the technical field of protective doors for civil air defense projects, and in particular relates to a processing method and production line for lightweight protective doors. Background technique [0002] With the rapid development of the national economy and changes in the international situation, national defense construction is constantly being strengthened. Civil air defense is an important part of national defense. In order to strengthen and improve the construction of civil air defense projects, the transformation of the civil defense industry and the application of new technologies and materials are very important. . Civil air defense closed doors and airtight doors are one of the very important protective equipment at the entrance and exit of civil air defense projects. For a long time, they have been made of traditional reinforced concrete protective airtight doors or multi-layer steel plates. Although they can play t...
