The processing modes and the difficulty degrees of different types of glue are different, and the materials selected during processing aiming at the glue with different viscosities are also different. Generally, the higher the grammage of the release film, the higher the degree of adhesion of the adhesive to the release film, so that the adhesive with high viscosity can properly reduce the grammage of the release film when selecting a load-bearing release film, while the adhesive with high viscosity needs to increase the grammage of the release film.
As shown in fig. 1, in the existing process for manufacturing adhesive materials, a carrier release film 2 is usually adhered to the lower surface of an adhesive material 1, and for the adhesive with the release film or release paper, the adhesive with the release film or release paper needs to be replaced. In order to ensure the adhesion degree, the low-viscosity glue is mostly selected from a load-bearing release film with higher gram weight during production and manufacturing, but the market share of the release film is lower, the purchase is not easy to find, the price is higher, the manufacturing cost is increased, and the manufacturing process is delayed.
SUMMERY OF THE UTILITY MODEL
The purpose of the utility model is to provide a viscidity bears from type membrane in order to overcome the defect that above-mentioned prior art exists for solve because the lower problem that leads to bearing from type membrane cost increase, delay the processing procedure of gluing type material viscidity.
The purpose of the utility model can be realized through the following technical scheme:
a kind of viscidity bears the release film, is used in the die cutting process of the low-viscosity glue material, the said viscidity bears the release film and includes the viscidity basement membrane, membrane located on the viscidity basement membrane, and offer the glue area hole on the membrane;
when the die cutting is carried out, the glue material is arranged in the glue area hole and is bonded with the viscous bottom film, the viscous bottom film is bonded with the glue material through the exposed viscous part in the glue area hole, and the adhesion degree between the viscous bottom film and the glue material is improved.
Furthermore, the sticky basement membrane comprises a basement membrane and a sticky layer arranged on the basement membrane, and the diaphragm is arranged on the sticky layer of the sticky basement membrane.
Further, the basement membrane includes the pellosil.
Furthermore, the adhesive layer is an adhesive silica gel coating arranged on the basement membrane.
Further, the diaphragm be from the type membrane, from type membrane both sides divide into from the profile and not from the profile, will not leave the profile and laminate mutually with the viscous layer during the use.
Further, the thickness of the diaphragm is not more than 0.3mm, so that the phenomenon that the thickness of the final glue product is too large due to too large thickness is avoided.
Furthermore, a gap is arranged between the glue area hole and the glue material, and the gap is used for avoiding the adverse effect caused by glue leakage of the viscous bearing release film.
Further, the size of the gap is 0.15-0.25 mm.
The working principle is as follows: the technical scheme includes that an original non-adhesive bearing release film is replaced by a low-viscosity bearing release film to improve the adhesion degree between the bearing release film and a rubber material, the diaphragm is attached to a common release film when the adhesive release film is used, the adhesive base film can be a viscous silica gel film, a non-release surface of the release film is attached to an adhesive surface of the silica gel film in the attaching process, then the contour of the rubber material is punched on the surface of the release film, the release film in the contour is removed, the adhesive surface of the viscous silica gel film is exposed, a rubber area hole is formed, and the rubber material to be processed is attached to the bearing release film through the rubber area hole; meanwhile, the glue materials and the glue on the viscous base film are low-viscosity glue, so that the subsequent tearing step cannot be influenced by the bonding of the glue materials and the viscous base film, and the die cutting processing process can be smoothly carried out.
Compared with the prior art, the utility model has the characteristics of it is following:
1) the low-viscosity bearing release film replaces the original non-viscosity bearing release film, so that the adhesion degree between the bearing release film and the glue material is improved, and the problem that the glue material and the bearing release film are easy to fall off due to infirm adhesion during the production of the low-viscosity glue material can be effectively solved;
2) because the glue material and the glue on the viscous base membrane are low-viscosity glue, the problem of degumming can not occur in the tearing process;
3) the membrane covers the viscous basement membrane so as to avoid the problem of glue leakage of the viscous layer in the punching process.
