A kind of manufacturing method of composite aluminum honeycomb panel

Abstract

The invention belongs to the field of aluminum honeycomb floor production used in high-speed trains, intercity trains, urban rail trains, and low- and medium-speed railway passenger cars, and specifically relates to a method for manufacturing a composite aluminum honeycomb panel; it includes the following steps: step 1, a panel and a back panel , Aluminum profile frame pretreatment steps; Step 2, aluminum honeycomb core pretreatment steps; Step 3, adhesive film pretreatment steps; Step 4, same temperature treatment; Step 5, assembly steps; Step 6, hot pressing curing steps; Step 7 , cold pressing solidification step; the present invention can not only prevent glue breaking and bubbling of the composite aluminum honeycomb panel used for the floor of high-speed bullet trains, intercity trains, urban rail trains, and medium and low-speed railway passenger cars, but also has the characteristics of simple operation and easy implementation and promotion.

Description

technical field [0001] The invention belongs to the field of production of aluminum honeycomb floors used in high-speed trains, intercity trains, urban rail trains, and medium- and low-speed railway passenger cars, and in particular relates to a manufacturing method of a composite aluminum honeycomb panel. Background technique [0002] The composite aluminum honeycomb panel is a neat flat cuboid as a whole, including aluminum alloy / steel plate panel, aluminum honeycomb core, aluminum alloy / steel plate back plate from top to bottom, and a circle of aluminum profile frame around the aluminum honeycomb core . Among them, the aluminum alloy / steel plate panel and the aluminum honeycomb core, the aluminum honeycomb core and the aluminum alloy / steel back plate are respectively connected by the first adhesive layer and the second adhesive layer, and the aluminum profile frame is connected by the third adhesive layer Enclosed around the aluminum honeycomb core. The manufacturing pr...

Problems solved by technology

[0004] When the above-mentioned composite aluminum honeycomb panel is applied to the floors of high-speed trains, intercity trains, urban rail trains, and medium- and low-speed railway passenger cars, there are the following defects: Among them, there are passengers in the riding area or sleeper area, passengers and salespersons walk back and forth on the floor in the aisle area, and large luggage is dragged on the floor when passengers get on and off the train. At the same time, high-speed bullet trains, intercity trains, Urban rail trains, medium and low-speed railway passenger cars are always shaking and bumping during operation, so the floor is used frequently, bears high pressure and friction, and bears shear force at the same time, and the use environment is harsh. Therefore, aluminum After a certain period of use, the honeycomb composite panel will have glue opening and bubbling, which will affect the appearance and service life of the aluminum honeycomb composite panel floor. In serious cases, it will even threaten the safety of passengers.

[0007] The above method of setting air holes in the aluminum honeycomb core structure to prevent glue opening is not suitable for the field of aluminum honeycomb composite board floors, because the floors of high-speed bullet trains, intercity trains, urban rail trains, and medium and low-speed railway passenger cars are made of small units of aluminum honeycomb composite panels. The panels are closely spliced, and its four sides are fixedly connected with the walls of high-speed bullet trains, intercity trains, urban rail trains, and medium and low-speed railway passenger cars. Ventilation holes or ventilation grooves are set in the core, which can not achieve the purpose of maintaining air circulation, and cannot solve the problem of floor glue opening
