Insulation double-sided tape and preparation process thereof

Abstract

The invention discloses an insulation double-sided tape and a preparation process thereof. The insulation double-sided tape comprises a first release film, a first double-sided adhesive film, an insulation film, a second double-sided adhesive film and a second release film which are sequentially attached to each other, one end of each of the first release film, the first double-sided adhesive film, the insulation film, the second double-sided adhesive film and the second release film is aligned, the first double-sided adhesive film, the insulation film, the second double-sided adhesive film are equal in length, the other end of the first release film is 5-10mm longer than the first double-sided adhesive film, and the second release film is 20-50mm longer than the second double-sided adhesive film. The insulation double-sided tape is compounded to be an integrated structure through mechanical equipment, after being completed, the insulation double-sided tape can be attached to the inner side of an LED (light emitting diode) lamp tube merely by one worker for usage, so that the manpower is saved, the compound cycle is shortened, the production efficiency is improved, the preparation process is completed through the mechanical equipment, the compound is fast, the accuracy is high, the product reject ratio is low, and the resource is saved.

Description

technical field [0001] The invention relates to a double-sided adhesive tape and a preparation process thereof, in particular to an insulating double-sided adhesive tape with both insulation and double-sided adhesive properties and a preparation process thereof. Background technique [0002] The development trend of electronic products such as notebook computers, tablet computers, LCD TVs, and liquid crystal displays is light and thin, resulting in smaller and smaller consumer electronics products. Traditional electronic components and auxiliary materials with single functions have been It cannot meet the light and thin development trend of electronic products, because the traditional single-function electronic components and their auxiliary materials need to be used after distribution and assembly. The assembly process consumes a lot of human resources and production time, and the production efficiency is low. Product qualification rate Low. [0003] For example, the adhes...

[0002] The development trend of electronic products such as notebook computers, tablet computers, LCD TVs, and liquid crystal displays is light and thin, resulting in smaller and smaller consumer electronics products. Traditional electronic components and auxiliary materials with single functions have been It cannot meet the light and thin development trend of electronic products, because the traditional single-function electronic components and their auxiliary materials need to be used after distribution and assembly. The assembly process consumes a lot of human resources and production time, and the production efficiency is low. Product qualification rate Low

[0003] For example, the adhesive tape used to fix and insulate the LED light tube in the liquid crystal module. At present, the tape is a split structure of insulating tape and double-sided tape. When assembling the liquid crystal module, first fix the insulating tape on the inside of the LED light tube, and then The insulation film of the insulating tape is laminated with 2 double-sided tapes at intervals along the width direction. The lamination process requires 3 stations, which greatly wastes human resources and production time, and the production efficiency is low. At the same time, when laminating the tapes manually, the lamination accuracy is not good. High, affecting the insulation and adhesive properties of the product
