Abstract

The invention discloses a device for preparation of an ultra-high molecular-weight polyethylene sheet. The device is characterized in that the device orderly comprises an extrusion mechanism, a rolling mechanism, a traction mechanism and a cutting mechanism; the extrusion mechanism comprises a planetary screw extruder; the planetary screw extruder comprises a multi-section combined cylinder mechanism; the multi-section combined cylinder mechanism comprises multiple cylinder sections connected with each other and multiple planetary screws embedded respectively in all the cylinder sections; a polyethylene material is extruded by the extrusion mechanism and then is rolled into a sheet by the rolling mechanism; and the sheet is drawn into the cutting mechanism by the traction mechanism and then is cut according to required sizes. The invention also discloses a method for preparation of the ultra-high molecular-weight polyethylene sheet. The device and the method for preparation of the ultra-high molecular-weight polyethylene sheet have a high automation degree and improve production efficiency.

Description

technical field [0001] The invention relates to the technical field of polymer material preparation, in particular to an ultra-high molecular weight polyethylene sheet preparation device and method. Background technique [0002] The market potential of UHMWPE sheet is huge. In the case of the same thickness, the weight of ultra-high molecular weight polyethylene high-strength sheet is only 1 / 8 of that of steel plate, its wear resistance is about 5 times higher, but its strength is equivalent, its corrosion resistance is better, and its impact strength is higher. As ultra-high molecular weight polyethylene is well known, its application fields are also expanding. For example, many parts such as car shells, mailboxes, bumpers, fenders, bottom guards, and compartment baffles can be processed and produced with composite panels of ultra-high molecular weight polyethylene sheets to reduce their weight; flexible containers for chemical plants , lightweight transparent roof panels...
