Description

Energy-saving release film for components

Technical Field

The utility model relates to the technical field of release films, in particular to an energy-saving release film for components.

Background

The release film generally comprises a single-layer base film and a layer of release agent coated on the base film, is generally used for protecting adhesive tapes or paper products, and can also be applied to the product manufacturing process in the IT field, such as the isolation protection of sheet-shaped components in the manufacturing process.

The production of the chip component is large, and a large number of release films are required. Since the adhesion between the release agent and the base film in a general release film is generally poor, the release film is mostly a disposable product. A large amount of release films are consumed in the process of manufacturing the sheet-shaped component, so that the production cost and the energy consumption are increased, a large amount of release film waste products are generated, the waste product treatment cost is increased, and improvement is needed.

Disclosure of Invention

The utility model aims to provide an energy-saving release film for components, which increases the adhesive force between a release agent and a base film, prolongs the use times and the service life, and improves the effects of reducing the cost and saving energy.

To achieve the purpose, the utility model adopts the following technical scheme:

an energy-saving release film for a component, comprising: the novel release agent comprises a first base film, a second base film, a bonding layer and a release agent layer, wherein the bonding layer is arranged on the upper surface of the first base film, the second base film is arranged on the upper surface of the bonding layer, the release agent layer is arranged on the upper surface of the second base film, storage holes are formed in the second base film in an array mode, the bottom of the release agent layer downwards extends into the storage holes, and the storage holes are filled.

Wherein, the bonding layer adopts a hot melt adhesive film or an adhesive.

Wherein, the first base film and the second base film adopt PET base film respectively.

The second base film adopts a square structure, and the storage holes are distributed on the second base film in a rectangular array.

Wherein, be provided with the first spread groove of connecting between adjacent 2 storage holes in width direction on the second base film.

And a second communication groove connected between 2 adjacent storage holes in the length direction is formed in the second base film.

The utility model has the beneficial effects that: the energy-saving release film for the component is particularly designed with a second base film, and a storage hole is designed on the second base film, and is filled with release agent in the coating process of the release agent layer, so that the adhesive force and stability of the release agent layer are increased, the problem of local falling off is reduced, the service life or the frequency of the release film is prolonged, the consumption and the cost of the release film are reduced, the problem of waste of the release film is reduced, and the energy-saving effect is improved.
