Abstract
The invention relates to a light-weight and high-strength thermoplastic composite material sandwich board and a production method thereof. The light-weight and high-strength thermoplastic composite material sandwich board comprises two panels and a sandwich layer, wherein the sandwich layer is fixedly arranged between the two panels. The preparation method comprises the following steps: putting the sandwich layer between the two panels; and sticking the two panels on the front and rear faces of the sandwich layer by a thermoplastic glue film through a hot pressing process and a cold pressing process to produce the thermoplastic composite material sandwich board. The panels are continuous fiber enhanced thermoplastic composite material boards and the sandwich layer is made of a honeycomb aluminum material. Compared with the prior art, the thermoplastic composite material sandwich board has the advantages of light weight, high strength, heat preservation, fireproof prevention, moisture prevention, corrosion prevention and the like.
Description
Technical field
The invention belongs to building decoration and technical field of traffic transportation, especially relate to thermoplastic composite battenboard of a kind of high-strength light and preparation method thereof.
Background technology
Along with scientific and technical fast development, for the sandwich sheet type of building decoration, traffic and transport field, emerge in an endless stream.Not only creative on the pattern of structure and sheet material, in function, also there is earth-shaking variation.People require not only attractive in appearance, reliable in quality to it, also require that quality is light, intensity is high, it is fire-retardant to have, the function such as insulation, heat insulation, anticorrosion.The battenboard of selling in the market has metallic plate and other class non-metal board, as wood based panel, plasterboard, glass epoxy etc.
Common metal battenboard is to combine with foamed plastics such as color steel and polystyrene, and Chinese patent CN201517251U discloses a kind ofly take color steel as panel, the insulation sandwich board that polyurethane foam is laminboard layer.
