Abstract
The invention discloses a processing and forming method of a plastic hollow plate with honeycomb holes, which comprises the following steps: S1, processing and manufacturing a plastic sheet by an extrusion and calendering method to serve as a surface layer sheet of the honeycomb plastic hollow plate; S2, carrying out an extrusion calendering method to obtain a plastic sheet to serve as a bottom layer sheet of the honeycomb plastic hollow plate; S3, carrying out extrusion calendering method to obtain a plastic sheet, and processing the plastic sheet into a meshed plastic sheet with honeycomb-shaped holes through a rotary die so as to be used as a core layer sheet of the honeycomb plastic hollow plate; and S4, sandwiching the core layer sheet between the surface layer sheet and the bottom layer sheet through a thermal bonding machine for thermal bonding. The honeycomb layer is clamped between the two surface layers, honeycomb distribution is uniform, the pressure resistance and shock resistance of the honeycomb-shaped hollow plate are remarkably superior to those of an existing through type hollow plate, and the transverse tearing strength and the longitudinal tearing strength of theplate are consistent and are also greatly superior to those of the existing hollow plate.
Description
technical field [0001] The invention relates to the technical field of plastic processing and molding, in particular to a processing and molding method of a plastic hollow plate with honeycomb holes. Background technique [0002] The plastic hollow board is a plastic board with a cross-section in the shape of a hollow grid obtained by extruding polyethylene, polypropylene, etc., air blowing, vacuum suction cooling and shaping. Plastic hollow boards are also called hollow partition boards, Wantong boards, corrugated boards, double-wall boards, etc., and can be made into boards of various colors and properties (such as flame retardant, antistatic, UV protection, etc.) by adjusting the formula. This kind of board is light in specific gravity, waterproof, moisture-proof, corrosion-resistant, and can be reused many times. It can be widely used in the manufacture of various plastic backing boards, back boards, packing boxes, turnover boxes, folding boxes, knife cards, pallets, etc...
