Thermoplastic cellular board and production method thereof, and double-steel-strip continuous press

Abstract

The invention discloses a thermoplastic cellular board and a production method thereof, and a double-steel-strip continuous press. The double-steel-strip continuous press comprises preheating mechanisms, steel strip mechanisms, roller blanket mechanisms and cooling and forming mechanisms, wherein the two roller blanket mechanisms are respectively arranged in respective annular spaces formed by the upper and lower steel strips; and the two roller blanket mechanisms in the annular space of each steel strip is arranged front and back. By adopting the upper and lower roller blanket mechanisms and the cooling and forming mechanisms inside, the cooling and forming process of the cellular board is divided into a first cooling section and a second cooling section, so that the sectional cooling and forming of the cellular board can be implemented according to the technical design demands, thereby effectively controlling the technical temperatures of the two cooling sections and enhancing the product quality and production efficiency. The thermoplastic cellular board produced by the production method and press has the advantages of stable cellular structure, favorable surface quality, high strength and large area.

Description

technical field [0001] The invention belongs to the field of manufacturing thermoplastic honeycomb panels, in particular to a double-steel-belt continuous press for producing thermoplastic honeycomb panels, a production method using the press, and thermoplastic honeycomb panels produced by the production method. Background technique [0002] The patent document with the publication number CN102689458A discloses a thermoplastic honeycomb panel and its preparation method. The honeycomb body is formed by thermal bonding of double-layer composite pipes, and the honeycomb base material is formed by cutting the honeycomb body. The honeycomb base material is hot-pressed to make it The surface layer is melted to form a glue bump, which is large in size and has a high connection strength, which is much higher than the bonding strength between the outer layers of the pipe or the connection strength of the small surface glue bump formed by hot wire cutting. For honeycomb panels with sm...

Problems solved by technology

However, the connection strength of thermoplastic honeycomb panels mainly depends on the rapid melting of the upper and lower ends of the surface layer to form glue bumps and timely cooling and shaping. However, the hot pressing process of the above-mentioned double-steel belt continuous press takes a long time. After hot-pressing and compounding the upper material layer between the moving rollers, it needs to be heated by the heating section, which will cause the heat to be transmitted to the inner core of the honeycomb base material and cannot be cooled in time, which will lead to the destruction of the honeycomb structure of the honeycomb plate and the surface of the honeycomb plate.
