Low-bubble release paper and preparation process thereof

Abstract

The invention discloses low-bubble release paper and a preparation process thereof, and belongs to the technical field of release paper preparation processes, the low-bubble release paper can influence the repulsive force between an electromagnet and a magnetic sheet by adjusting the current of the electromagnet so as to change the length of a push-and-pull cylinder, so that the push-and-pull cylinder can play a push-and-pull role on a pre-detection tube, and the pre-detection tube is prevented from being damaged. In this way, the standard thickness of the backing paper can be determined, the device is also suitable for pre-checking backing paper of different specifications and thicknesses, the color prompting lamps of the corresponding colors are turned on through contact between the trigger piece and the different contacts, a user can visually see the uniformity of the thickness of the backing paper, and therefore the backing paper of different qualities can be classified; compared with the prior art, the release paper has the advantages that the lower bottom paper is further improved, so that the probability that bubbles are generated due to high temperature after the lower bottom paper is processed is reduced, meanwhile, a batch of high-quality release paper can be produced, the bottom paper is more attached to the laminated film, the use performance is improved, and the selling price is also increased.

Description

technical field [0001] The invention relates to the technical field of release paper preparation technology, more specifically, relates to a low-bubble release paper and its preparation process. Background technique [0002] The release paper is a kind of anti-adhesive paper that prevents the prepreg from sticking and protects the prepreg from contamination. The release paper is made of paper coated with anti-adhesive substances, and its type should be distinguished according to the difference in material, thickness, elongation, and single-sided and double-sided. [0003] Release paper is also called silicone oil paper. It consists of three layers, the first layer: bottom paper; the second layer: laminating film; the third layer: silicone oil. Can be used in electronic products, automotive foam, printing, food, medical and so on. In most cases it is used with sticky materials, especially adhesive tapes. [0004] However, in the process of processing the existing release ...

Problems solved by technology

[0004] However, in the process of processing the existing release paper, due to the uneven thickness of the backing paper, the sagging between the backing paper and the coating film is poor, thereby creating a gap between the backing paper and the coating film, and making the processed When the release paper encounters high temperature, a large number of air bubbles will be generated, which not only reduces the peeling force of the release paper, but also affects its performance
