Embodiment 1

[0032] A kind of large-scale thick-walled polymer wood board production equipment of the present invention, its structure is as follows figure 1 As shown, the equipment includes a kneader 5, a track 2, a mold 13, a hydraulic press 11, and a demoulding mechanism 14 arranged in sequence along the conveying direction of the mould; the kneader 5 is controlled by a kneader electric control cabinet 7, and the kneader cylinder 9 is a Machine 5 provides a heat source. After the materials are mixed in kneader 5, they are sent to mold 13 on track 2 from outlet 3 below kneader 5. The track rollers drive mold 13 into hydraulic press 11, and hydraulic press 11 passes through the lower template 4 plunger oil cylinders 18 control its movement, and after the raw material is molded in the hydraulic press 11, the product is ejected by 6 ejection cylinders 16 of the demoulding mechanism 14 to realize demoulding.

[0033] The specification of the mold 13 of this embodiment is 4600mm×1300mm (lengt...

Embodiment 2

[0043] Molding equipment is the same as implementation example 1. The specification of the mold 13 in this embodiment is 4600mm×1300mm (length×width), and the thickness of the prepared polymer wood board is 150mm.

[0044] The material used in this implementation example is recycled waste polypropylene and polyethylene and polyvinyl chloride, crushed wood chips, ternary block copolymer polyethylene glycol-aliphatic polyester-polyamino acid, crosslinking agent N, N'- Methylene bisacrylamide, plasticizer polydibutyl adipate, reinforcing filler silicon whiskers.

[0045] First open the control cabinet 8 of the kneader oil cylinder and power on the kneader oil cylinder 9 to preheat the circulating oil to 220°C. In winter when the temperature is low, increase the preheating time appropriately so that the circulating oil can reach 220°C as much as possible. When the oil temperature is appropriate, turn on the kneading The machine top cover 6 puts the prepared waste plastics and str...

Abstract

The invention relates to laminated wood plate forming equipment and a laminated wood plate forming method, in particular to laminated wood material forming equipment and a laminated wood material forming method, which form a new composite material with high strength, high hardness and low cost by plasticizing mixed recovered waste plastics, kneading the plasticized mixed recovered waste plastics, a crushed wood fiber material and a processing assistant and die-pressing to form a common continuous phase structure. The production equipment comprises a kneading machine (5), a rail (3), a hydraulic press (11), a demolding mechanism (14) and a corresponding control panel.

Description

technical field [0001] The invention relates to a processing and molding method for polymer wood materials, in particular to a molding device and a molding method for large-size thick-walled polymer wood building boards. Background technique [0002] Polymer wood is a full cycle, high environmental protection and economical new material that can replace plastic, wood, steel, aluminum, cement, etc. Polymer wood is to use unclassified mixed waste plastics to add inorganic materials, wood fiber materials, multi-block copolymers, cross-linking agent plasticizers and other raw materials, and use reaction initiators to initiate chemical reactions to promote plasticization and re-polymerization of plastic materials. After compounding, a new type of material whose strength is much higher than that of wood and whose texture is closest to wood is manufactured by plastic processing methods. It is the only material that fully utilizes all the components of plastic materials, does not e...
