Abstract

The invention belongs to the technical field of building decoration and transportation, and discloses a light-weight and high-strength plastic steel sandwich board and its making method. The plastic steel sandwich board comprises two panels and a sandwich layer fixed between the two panels. The making method of the plastic steel sandwich board comprises the following steps: placing the sandwich layer between the two panels, and respectively bonding the two panels with the right and wrong surfaces of the sandwich layer through an adhesive to prepare the plastic steel sandwich board, wherein each of the panel is obtained through compounding one side of a continuous fiber reinforced thermoplastic plastic board with a non-woven fabric through hot-press molding. The plastic steel sandwich board has the advantages of light weight, high strength, heat insulation, fire resistance, moisture resistance, corrosion resistance and the like.

Description

technical field [0001] The invention belongs to the technical fields of building decoration and transportation, and relates to a light-weight and high-strength plastic-steel sandwich panel and a preparation method thereof. Background technique [0002] With the rapid development of science and technology, there are endless types of sandwich panels used in the fields of building decoration and transportation. Not only is the structure and panel style ingenious, but also the function has undergone earth-shaking changes. People require not only beautiful appearance and reliable quality, but also light weight, high strength, flame retardant, heat preservation, heat insulation, anti-corrosion and other functions. Sandwich panels currently on the market include metal panels and other types of non-metallic panels, such as wood panels, gypsum panels, and glass steel panels. [0003] Commonly used metal sandwich panels are composed of color steel plates and foamed plastics such as ...
