Example Embodiment

[0021] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0022] A dimple-shaped honeycomb hollow panel, characterized in that: the internal structure of the dimple-shaped honeycomb hollow panel comprises an upper skin layer, a dimple-shaped honeycomb structure layer and a lower skin layer, and the dimple-shaped honeycomb structure layers are up and down. Staggered inlaid sandwich structure.

[0023] The composition and percentage weight ratio of the internal structure of the upper skin layer are: 78% polypropylene, 12% talc, 2% polyethylene, 1% maleic acid, 1% calcium carbonate, 1% titanium dioxide , 1% aluminum oxide, 0.5% antioxidant 1010, 0.1 ultraviolet absorber UV-327, 0.4% coupling agent KH-550, 3% masterbatch uniformly mixed composition, dried in a dryer at 120 ℃ for 2 hours The upper skin layer mixture is obtained.

[0024] The composition and percentage weight ratio of the internal structure of the dimple-sha...

Abstract

The invention relates to a dimple-shaped honeycomb hollow plate and a manufacturing method thereof, which belong to a manufacturing method of a multilayer co-extrusion molding hollow plate. The dimple-shaped honeycomb hollow plate is characterized in that an internal structure comprises an upper skin layer, a dimple-shaped honeycomb structure layer and a lower skin layer, wherein the dimple-shaped honeycomb structure layer is of an inlaid type sandwich structure in an up-and-down staggered mode. The dimple-shaped honeycomb hollow plate is provided, so as to overcome the defects of poor impact resistant performance, compressive deformation and infirmness of an existing plastic hollow plate, and the dimple-shaped honeycomb hollow plate has good performances of high strength, pressure resistance, wear resistance, heat insulation, impact resistance and breaking resistance, can simultaneously bear transverse section stress, longitudinal section stress and plate positive stress and has the advantages of uniform stress of each side surface, wide application range and good use effect.

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 a multi-layer co-extrusion hollow board, in particular to a kind of extrusion through a three-layer co-extrusion machine, high-temperature hot air, hot pressing and hot melting. Dimple shape honeycomb hollow panel. 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 easy to b...
