Problems solved by technology

For the production of thermoplastic resin multilayer composite sheets, including bonding, heat sealing and other methods, it is also possible to use the method of extruding each layer of sheet and compounding it when it is not completely cured, but because the materials of each layer are different, The curing shrinkage rate is different, resulting in a loose bond between the layers, which is easy to cause the loss of function

Abstract

The invention belongs to the field of sheet preparation and relates to a thermoplastic resin composite sheet production device and process. The thermoplastic resin composite sheet production device comprises a substrate forming mechanism and at least one composite layer forming mechanism. Each composite layer forming mechanism is integrally positioned above a conveying belt (202) and comprises a magnetic fiber laying device, a magnetic field generating unit (402) and a cooling roller (303) from one side close to a die head I (101), wherein the magnetic fiber laying device is used for laying fibers on substrate slurry (501), the magnetic field generating unit (402) is capable of generating a magnetic field perpendicular to the ground, and the cooling roller (303) is used for receiving composite layer slurry (502) from a die head II (102) to enable cooling of the composite layer slurry (502) on the cooling roller (303). The thermoplastic resin composite sheet production device is simplein structure and easy in operation.

Description

technical field [0001] The invention relates to a thermoplastic resin composite sheet production device and process, belonging to the field of sheet preparation. Background technique [0002] For thermoplastic resin composite sheets, especially layered thermoplastic resin composite sheets, due to different requirements for their functions, each layer needs to have different properties, or the main properties are mainly exerted by the surface layer material. For the production of thermoplastic resin multilayer composite sheets, including bonding, heat sealing and other methods, it is also possible to use the method of extruding each layer of sheet and compounding it when it is not completely cured, but because the materials of each layer are different, The curing shrinkage rate is different, resulting in a loose bond between layers, which can easily lead to loss of function. Contents of the invention [0003] In view of the above technical problems, the object of the prese...
