Abstract
The invention belongs to the technical field of adhesive sticker manufacturing, and relates to a manufacturing method of an anti-bubble non-base-material adhesive sticker, which comprises the following steps: coating a substrate-free adhesive on the surface of a spread plastic film, pressing the substrate-free adhesive to a certain thickness by using a pressing roller, and attaching a protective film on the surface of the substrate-free adhesive; tearing off the plastic film from the non-base material adhesive, and then attaching the non-base material adhesive to the surface of the abrasive paper; and thirdly, cutting off the redundant part without the base material adhesive from one side of the protective film without cutting off the abrasive paper, and then removing the unnecessary area without the base material adhesive by using continuous protective film waste materials. According to the method, the abrasive paper is used as the adhesive material without the base material glue, so that the problem that air bubbles are easy to generate in use is avoided, and the actual needs of customers are met.
Description
Technical Field
The invention relates to the technical field of adhesive sticker manufacturing, in particular to a manufacturing method of an anti-bubble non-base-material adhesive sticker.
Background
In electronic products, thin film products are used for covering so as to achieve the purposes of dust prevention, insulation and the like, and glue is needed to be used for fixing the thin films. The film product delivered from factory is generally composed of a back film, an adhesive film and a protective film.
When the adhesive film belongs to the non-base material adhesive, the adhesive needs to be coated on the plastic film on site, then the protective film is pasted, then the range without the base material adhesive is cut, the pasted adhesive film area is reserved, when the adhesive film is used, the plastic film is peeled from the non-base material adhesive, and then the non-base material adhesive is pasted on the pasted surface of the notebook computer and other products.
Although the product produced in this way has no visible defects, in the actual use process, it is found that no bubbles are left for any reason after pressing without the base material glue, which results in incomplete gluing of the glue paste, an unsightly appearance and an unsatisfactory protective effect.
There is therefore a need for an improved method to avoid the above problems.
Disclosure of Invention
The invention aims to provide a manufacturing method of an anti-bubble base-material-free adhesive sticker, which can prevent the base-material-free adhesive sticker from generating bubbles in use.
The invention realizes the purpose through the following technical scheme: a manufacturing method of an anti-bubble base material-free adhesive sticker comprises the following steps:
coating a substrate-free adhesive on the surface of a spread plastic film, pressing the substrate-free adhesive to a certain thickness by using a pressing roller, and attaching a protective film on the surface of the substrate-free adhesive;
tearing off the plastic film from the non-base material adhesive, and then attaching the non-base material adhesive to the surface of the abrasive paper;
and thirdly, cutting off the redundant part without the base material adhesive from one side of the protective film without cutting off the abrasive paper, and then removing the unnecessary area without the base material adhesive by using continuous protective film waste materials.
Specifically, the adhesive force strength of the protective film to the non-base material adhesive is higher than that of the plastic film and the abrasive paper to the non-base material adhesive.
Specifically, the process of adhering the non-base material adhesive to the surface of the abrasive paper is realized by rolling a pair of closely adhered rubber rollers.
Specifically, after the third step, a knife is pulled down from one side of the sandpaper to remove the excess sandpaper, and a pulling part which is not covered by the base material glue is left on the protective film.
By adopting the technical scheme, the technical scheme of the invention has the beneficial effects that:
according to the method, the abrasive paper is used as the adhesive material without the base material glue, so that the problem that air bubbles are easy to generate in use is avoided, and the actual needs of customers are met.
Detailed Description
The present invention will be described in further detail with reference to specific examples.
Example (b):
the invention relates to a manufacturing method of an anti-bubble base material-free adhesive sticker, which comprises the following steps:
coating a substrate-free adhesive on the surface of a spread plastic film, pressing the substrate-free adhesive to a certain thickness by using a pressing roller, and attaching a protective film on the surface of the substrate-free adhesive;
tearing off the plastic film from the non-base material adhesive, and then attaching the non-base material adhesive to the surface of the abrasive paper;
and thirdly, cutting off the redundant part without the base material adhesive from one side of the protective film without cutting off the abrasive paper, and then removing the unnecessary area without the base material adhesive by using continuous protective film waste materials.
According to the method, the abrasive paper is used as the adhesive material without the base material glue, so that the problem that air bubbles are easy to generate in use is avoided, and the actual needs of customers are met.
The adhesive force strength of the protective film to the non-base material glue is higher than that of the plastic film and the abrasive paper to the non-base material glue. In order to prevent no substrate adhesive from remaining on one side of the plastic film during the manufacturing process, the protective film needs to have stronger adhesive force to the adhesive film. The abrasive paper needs to have low adhesive force strength to lead the redundant adhesive film part to be taken away along with the protective film waste.
The process of attaching the non-base material adhesive to the surface of the abrasive paper is realized by rolling a pair of closely attached rubber rollers. The rubber roller is used for linearly adhering abrasive paper to the surface of the rubber film, so that gas between contact surfaces can be favorably removed, and bubbles are prevented from being left in a product.
And step three, cutting off the side of the abrasive paper to remove the redundant abrasive paper, and leaving the lifting part without the base material glue on the protective film. The lifting part is used for further removing the protective film after the adhesive film is attached to the surface of the notebook computer, so that other parts can be conveniently and continuously attached to the upper surface of the adhesive film.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the invention.
