Production equipment and production method of ultra-high molecular weight polyethylene composite film

Abstract

The invention relates to production equipment and a production method of an ultra-high molecular weight polyethylene composite film. The production equipment comprises a rubber elastic layer supply device, an ultra-high molecular weight polyethylene layer supply device, a four-roller calender, a vulcanization drying tunnel, an embossing roller group, a cooling device and a wind-up roller. The production method comprises the following steps: supplying a rubber elastic layer raw material to an upper roller and a side roller of a four-roller calender by adopting a rubber elastic layer supply device, and inducing vulcanization through heating and rolling; an ultra-high molecular weight polyethylene layer supply device is adopted to supply an ultra-high molecular weight polyethylene layer to the middle roller and the lower roller, and the ultra-high molecular weight polyethylene layer and the rubber elastic layer are subjected to rolling compounding; the composite film which is not completely vulcanized enters a vulcanization drying tunnel to be fully vulcanized; the embossing roller group is used for embossing the surface of the rubber elastic layer; and then cooling, shaping and rolling. According to the production equipment and the production method, the interlayer cohesiveness of the ultra-high molecular weight polyethylene layer and the rubber elastic layer and the external cohesiveness of the composite film can be improved, and automatic and large-scale continuous production can be achieved.

Description

technical field [0001] The invention belongs to the field of ultra-high molecular weight polymer molding and processing, and particularly relates to a production equipment and a production method of an ultra-high molecular weight polyethylene composite film. Background technique [0002] Ultra-high molecular weight polymer refers to a polymer material with extremely high molecular weight, which has excellent comprehensive properties, especially excellent properties that ordinary polymer materials do not have. For example, ultra-high molecular weight polyethylene (UHMWPE) is a new thermoplastic engineering material with excellent properties such as impact resistance, wear resistance, self-lubrication, non-toxicity, chemical inertness, low temperature resistance, etc. It is widely used in textile and paper making , food, chemical, packaging, construction, medical, military and other fields. [0003] Wind turbine blades are one of the core components of wind turbines, and thei...

Problems solved by technology

[0010] However, none of the above-mentioned documents describe the production equipment and production methods of ultra-high molecular weight polyethylene composite films in detail.

Secondly, the additives added to improve the processing performance of ultra-high molecular weight polyethylene may easily lead to a decrease in the molecular weight of ultra-high molecular weight polyethylene or a decrease in other comprehensive properties, which cannot meet the needs of wind turbine blades.
