Silica gel and PET bonding process

Abstract

The invention belongs to the technical field of bonding, in particular to a silica gel and PET bonding process. A first reel and a second reel are commonly connected between the front and back side walls of a bonding box, and the surfaces of the first reel and the second reel are respectively connected to a silica gel film and a PET film in a wound manner; a first transmission shaft, a second transmission shaft and a first bonding shaft are commonly connected between the front and back side walls of the bonding box; a third transmission shaft, a fourth transmission shaft and a second bonding shaft are commonly connected between the front and back side walls of the bonding box; two glue spraying pipes are commonly connected with the front and back side walls of the bonding box to the rightside positions of the second transmission shaft and the fourth transmission shaft; and a high-temperature box is disposed at the right side position of the bonding box. The silica gel and PET bondingprocess effectively implements automatic bonding of the silica gel film and the PET film, achieves higher efficiency and more stable quality, reduces the labor cost, and can effectively perform high-temperature pressure maintenance processing, so that a finished combined film is more excellent in quality and higher in bonding firmness, and the rejection rate of the product is reduced.

Description

technical field [0001] The invention belongs to the technical field of bonding, in particular to a bonding process of silica gel and PET. Background technique [0002] Silica gel, also known as silicic acid gel, is a granular porous silica hydrate. It is an amorphous substance with a transparent or milky white appearance. It is made by adding acid to sodium silicate and then washing and drying. It has stable chemical properties and does not burn. ;PET is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. It has excellent physical and mechanical properties in a wide temperature range. The long-term use temperature can reach 120 ° C. Under high frequency, its electrical performance is still good, but its corona resistance is poor, and its creep resistance, fatigue resistance, friction resistance and dimensional stability are all good. [0003] In the prior art, the silica gel film and the PET film need to be bonded manually, which not o...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology and solve the problem that the silicone film and the PET film need to be bonded manually, not only the efficiency is low, but the labor cost is high, and the quality is unstable, and human factors interfere with the quality. Many, the defective rate is high, so the material cost will also increase, especially through manual glue application, the uniformity of the adhesive glue is difficult to guarantee, so there will be no adhesive glue and sticky glue at the bonding position of the silicone film and the PET film. Therefore, the quality of the obtained laminated film is poor, and it is difficult to meet the high-quality requirements of customers. The present invention proposes a bonding process for silica gel and PET
