Abstract
The invention discloses a dimple-shaped honeycomb hollow plate and a manufacturing method thereof, belonging to a manufacturing method of a multiplayer co-extruded molding hollow plate. The dimple-shaped honeycomb hollow plate is characterized in that an internal structure of the dimple-shaped honeycomb hollow plate comprises the following components in percentage by weight: 60-80 percent of polypropylene, 5-15 percent of talcum powder, 1-10 percent of polyethylene, 0.5-2.5 percent of aliphatic ester, 0.5-2.5 percent of calcium carbonate, 1-10 percent of titanium dioxide, 1-10 percent of aluminum oxide and 10-20 percent of glass fiber. The dimple-shaped honeycomb hollow plate is of a sandwich structure and structurally comprises an extrusion molding surface panel at the upper layer, a dimple-shaped honeycomb structure layer as a middle core layer and an extrusion molding surface panel at the lower layer. The manufacturing method of the dimple-shaped honeycomb hollow plate comprises the following steps: proportioning and mixing raw materials; plastifying and pelleting; extruding the extrusion molding surface panels at the upper layer and the lower layer by an extruder, and extruding a dimple-shaped honeycomb structure layer (formed by means of a vacuum plastic suction roller) by the extruder, performing corona treatment, performing hot-press and hot-melting splicing, annealing by a stress removing box, shaping and sizing by five rollers, cooling by an air cooling frame, forming and cutting to manufacture the dimple-shaped honeycomb hollow plate.
Description
technical field [0001] The invention relates to a dimple-shaped honeycomb hollow board and its manufacturing method, which belongs to the manufacturing method of multi-layer co-extruded hollow boards, in particular to a dimple formed by extruding through a three-layer co-extrusion machine and forming once by high-temperature hot-pressing and hot-melting Shape honeycomb hollow board. Background technique [0002] At present, it is used in many fields such as turnover logistics equipment and plastic construction. Plastic hollow boards are more and more widely used. Plastic hollow boards are mainly extruded by plastic extruders and produced by vacuum shaping in hollow grid board molds. , but there are many restrictions on the application of these plastic hollow boards, basically they are mainly used in places where the weight of the goods is light or as a backing plate or a partition. It is composed of ribs, the strength is not high, not strong, the force is not strong, it is ...
