Problems solved by technology

However, the method for preparing the ordered microstructure composite material in this method is to put the composite material into a mold, and then place the mold in a magnetic field to solidify at room temperature, which is a batch method, so the composite material preparation efficiency is low; and, the The composite material prepared by the method is limited by the size and cost of the mold, and the size range of the composite material is very narrow
At the same time, due to the limitation of the preparation process of this method, the resin matrix of the prepared ordered microstructure composite material is almost all thermosetting, and does not involve the preparation of thermoplastic resin matrix composite materials.

Embodiment 1

[0035] Weigh ferrite:epoxy resin:tetraethylenepentamine (curing agent) in a mass ratio of 1:10:2, mix, then ultrasonically disperse, and vacuum degas to obtain a ferrite / epoxy resin composite material liquid. The liquid is introduced into the thermosetting composite raw material casting extrusion groove in the coating system, and the composite material is extruded and coated on the base film. Start the DC servo motor with a speed of 2r / min, the motor drives the bottom film to move, adjust the height of the thickness control plate, and control the thickness of the composite film. When the composite material enters the magnetic field processing system, it is heated with a heating tube, and the temperature of the heating tube is controlled at about 40°C, so that the epoxy resin is gradually pre-cured during the process of ordering the ferrite. When the composite came out of the magnetic field, the epoxy crosslinked enough to hold the ordered ferrites in place. Then the composite...

Embodiment 2

[0037] Dissolve 5g of polyvinyl alcohol (PVA) with a polymerization degree of 1750 in 50ml of water at 85°C, add 1g of ferrite, stir, and then transfer the composite material solution to a thermoplastic raw material casting extrusion tank at a temperature of 85°C, At this point, heat the heating plate to 85°C, then extrude the composite material and coat it on the bottom film, start the DC servo motor at a speed of 2r / min, the motor drives the bottom film to move, adjust the height of the thickness control board, and control the thickness of the composite film . When the composite material enters the magnetic field treatment system, it is heated and dried with a heating tube, and the temperature is controlled at about 60°C, so that the composite material still has a certain fluidity, so that the ferrite can be well ordered in the magnetic field system. After the composite material comes out of the magnetic field, it is cooled and dried at room temperature, so that the ordered ...

Abstract

The apparatus for preparing ordered micro structure resin base composite material film consists of a tension control system, a composite material film coating system, a magnetic field processing system, a heating treatment system, a DC servo speed regulating motor, a pedestal and other parts. All the systems are fixed successively on the pedestal. In the apparatus, ordered micro structure resin base composite material film is formed through driving the base film with the DC servo speed regulating motor, coating the resin base composite material onto the base film in the composite material film coating system, ordering the micro structure in the composite material and pre-curing in the magnetic field processing system, and final curing through heating in the heating treatment system. Compared with available technology, the present invention has the features of capacity of producing ordered micro structure composite material film in different direction, etc.

Description

technical field [0001] The invention relates to a continuous preparation device for a resin-based composite material film with an ordered magnetic response microstructure. Among them, the ordering includes the ordering of the array perpendicular to the film plane and the ordering of the alignment parallel to the film plane (the longitudinal direction of the film and the transverse direction of the film); the microstructure includes functional groups or segments in the resin macromolecules, Crystal structure, adding fine particles, etc. Background technique [0002] Magnetic composite material refers to a permanent magnetic composite obtained by mixing, molding and curing with a permanent magnet powder as a functional body. Because it can prepare large, medium and small products with precise dimensions, low shrinkage, thin walls and complex shapes at one time, it can also be easily processed by secondary cutting, and at the same time has good impact resistance and tensile st...
