Abstract
A method of producing and the product of heat-proof laminate boards are disclosed. Each laminate board cut from a continuous laminate has a corrugated upper layer, a middle foam layer produced by spraying foam agent onto one side of the upper layer which will expand into shape automatically, a bottom layer having opposite edges folded in conformance to the corresponding edges of the upper layer so as to sealedly confine the foam in between the upper layer and bottom layer. The upper layer can be made of one of the materials including steel plate, PVC, PC, PP, aluminum plate, iron sheet. The bottom layer is made of materials including PVC film, PP film, papery film, fabric film, nylon film or wooden fiber sheet.
