Abstract

The invention provides a device and process for producing large-thickness and ultra-thin polyvinyl chloride (PVC) films and relates to the technical field of preparation of PVC films. The device comprises a compounding mixer, a rubber extruder, a drum-type cooling extrusion compounding machine, a cooling machine, a hauling machine and a reeling machine. The process comprises the following steps: uniformly mixing raw materials and accessories in the compounding mixer, and conveying the mixture into the rubber extruder; then extruding sheet bands out from an extrusion mold head of the rubber extruder, then feeding the sheet bands into the drum-type cooling extrusion compounding machine, and compounding the sheet bands with combined fabrics and prepared PVC films; and cooling the compounded films in the cooling machine, and then reeling the films. The processing is as follows: compounding and mixing, melting, extrusion cooling compounding, cooling and reeling. The process has the advantages that the process is innovative; a screw extrusion-assisted external heating method is adopted so as to melt PVC raw materials at a high temperature, and the drum-type cooling extruder is adopted for cooling, so that the process has environmental friendliness, energy conservation and high production efficiency.

Description

technical field [0001] The invention relates to the technical field of PVC film manufacture, in particular to a production equipment and process for producing large-thickness and extra-thin PVC films. Background technique [0002] At present, in the process of PVC film processing and manufacturing, it is relatively easy to process ultra-thin films, but it is still difficult to realize the processing of large-thickness films. In practical applications, large-thickness PVC films have many uses. It is very necessary to have production equipment and techniques for producing ultra-thin PVC film with large thickness. Contents of the invention [0003] The object of the present invention is to provide a kind of production equipment and technology of producing large thickness and ultra-thin PVC film, to solve the problem proposed in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: ...
