Abstract
The present application provides an insulating composite plate comprising: an upper plate layer, a lower plate layer, and a middle plate layer, wherein the upper plate layer and the lower plate layer are made of a thermoplastic material; the middle plate layer is located between the upper plate layer and the lower plate layer, the middle plate layer being a metal mesh; the upper surface of the middle plate layer and the lower surface of the upper plate layer are bonded together, and the lower surface of the middle plate layer and the upper surface of the lower plate layer are bonded together. An insulating composite plate provided by this application has good insulation properties and can shield electromagnetic interference.
Claims18
An insulating composite plate, comprising:
- an upper plate layer and a lower plate layer, the upper plate layer and the lower plate layer being made of a thermoplastic material;
- and
- a middle plate layer located between the upper plate layer and the lower plate layer, the middle plate layer being a metal mesh;
- the upper surface of the middle plate layer and the lower surface of the upper plate layer are bonded together, and the lower surface of the middle plate layer and the upper surface of the lower plate layer are bonded together.
A method for producing an insulating composite plate, the method comprising:
- (a) extruding particles of a first thermoplastic material on an extruder to melt it to form a first thermoplastic material in a molten state;
- (b) the first thermoplastic material in a molten state flows out of the extruder and enters a head die through a connecting pipe and is formed into a first plate thermoplastic material in the head die;
- (c) providing a metal mesh;
- (d) simultaneously conveying the metal mesh and the first plate thermoplastic material to a cooling molding roll so that the first plate thermoplastic material is press-fitted on one surface of the metal mesh to form a press-fitted sheet composed of the first plate thermoplastic material and the metal mesh;
- (f) extruding particles of a second thermoplastic material on the extruder to melt it to form a second thermoplastic material in a molten state;
- (g) the second thermoplastic material in a molten state flows out of the extruder and enters the head die through the connecting pipe and is formed into a second plate thermoplastic material in the head die;
- and
- (h) simultaneously conveying the press-fitted sheet and the second plate thermoplastic material to the cooling molding roll so that the second plate thermoplastic material is press-fitted on the other surface of the metal mesh, forming the insulating composite plate comprising a middle plate layer composed of the metal mesh and an upper plate layer and a lower plate layer respectively composed of the first plate thermoplastic material and the second plate thermoplastic material.
