Problems solved by technology

[0002] The stator of a million-level generator is often analyzed and fixed by filling glue at the end. The glue filling structure at the end has technical advantages such as firmness, reliability, and clean end, but there are some important shortcomings as follows: (1) Once the coil fails, Maintenance and replacement are required; due to the end glue filling structure, when disassembling and replacing the coil, it is inevitable not to damage other coils and cause unnecessary losses; (2) During the glue filling process, there is inevitably air around the coil Small gaps; these small air gaps can cause discharges in the air gap between the coils, which can affect the life of the main insulation
[0004] At present, film adhesive tapes made of polytetrafluoroethylene film and polyimide film have appeared; products made of these two materials meet the application requirements, but the raw material prices are high, and it is difficult to form cost competition Advantage

Embodiment Construction

[0016] The polyethylene film is UHMW-PE ultra-high molecular weight polyethylene film from Yangzhong Shuguang Fluoroplastic Co., Ltd.; the adhesive is DS160 adhesive from Shenzhen Shili Adhesive Co., Ltd.

[0017] Preheat the oven of the glue applicator, heat and maintain the temperature at 100°C; put the adhesive into the glue tank of the glue applicator, and complete the preparation work.

[0018] Guide the polyethylene film to the guide roller of the gluing machine, and then start gluing, use a rubber roller to roll on the surface of the film on one side for gluing, and then scrape the surface of the film coated with glue with the squeegee; The part is transported to the oven by the guide roller; after the pressure roller is released, it is directly wound and cut to obtain the product. During the process, the film speed was 3m / min.

[0019] Prepared polyethylene film adhesive tape, test result is as follows:

Abstract

The invention provides a polyethylene film adhesion tape and a preparation method thereof. A polyethylene film and adhesive are compounded to form the polyethylene film adhesive tape. The polyethylene film adhesion tape and the preparation method have the advantages that processing technology is simple and convenient, performances of a product are excellent, and the product is remarkably superior to a teflon film and a polyimide film in terms of price.

Description

technical field [0001] The invention relates to a polyethylene film adhesive tape and a preparation method thereof. Background technique [0002] The stator of a million-level generator is often analyzed and fixed by filling glue at the end. The glue filling structure at the end has technical advantages such as firmness, reliability, and clean end, but there are some important shortcomings as follows: (1) Once the coil fails, Maintenance and replacement are required; due to the end glue filling structure, when disassembling and replacing the coil, it is inevitable not to damage other coils and cause unnecessary losses; (2) During the glue filling process, there is inevitably air around the coil Small gaps; these small air gaps will cause the phenomenon of discharge in the air gap between the coils, which will affect the life of the main insulation. [0003] The above problems can be better solved by adopting the method of winding the film adhesive tape on the coil. The sur...
