Description
Technical Field
The invention belongs to the technical field of release films, and particularly relates to a release film with ultra-light release force.
Background
The release film refers to a film with a differentiated surface energy, and the release film has no viscosity or slight viscosity after being contacted with a specific material under limited conditions. In general, in order to increase the release force of the plastic film, the plastic film is subjected to plasma treatment, or fluorine coating, or silicon (silicone) release agent is coated on the surface layer of the film material, such as PET, PE, OPP, etc.; so that the rubber can show extremely light and stable release force for various organic pressure-sensitive adhesives (such as hot-melt adhesives, acrylic adhesives and rubber pressure-sensitive adhesives). According to different required release film release forces and different viscosities of isolation product glue, the release force is correspondingly adjusted, so that the extremely light and stable release force is achieved during stripping. The more the electronic parts are refined, the different parts are produced by different manufacturers, and the electronic products are assembled after the assembling manufacturers purchase the parts. The electronic parts generally need all use release film to protect after production is accomplished, avoids receiving pollution destruction such as dust in storage, transportation process. With the popularization of the automation process, downstream manufacturers basically use robots and other automation equipment for production. Release films on parts of electronic products need to be peeled off before assembly. The peeling of release films is also increasingly tending towards automatic machine suction peeling. This makes the release force of the release film more stringent.

Example 1
As shown in figure 1, a ultralight is from type membrane of type power, including substrate 1 and the silicon oil layer of coating on substrate 1, the one side that is used for coating the silicon oil layer on substrate 1 is equipped with the cutting that a plurality of even intervals set up, the silicon oil layer is including interior silicon oil layer 2 and outer silicon oil layer 3, and interior silicon oil layer 2 is full of the cutting and covers substrate 1 surface, and outer silicon oil layer 3 covers the surface at inner strata high viscosity silicon oil layer 2 through the mode of secondary coating after the solidification of interior silicon oil layer 2. The surface area of the substrate 1 is increased by using the groove, so that the contact area of the inner silicon oil layer 2 and the substrate 1 is greatly increased, and meanwhile, the cured inner silicon oil layer 2 can form larger binding force with the substrate 1 in the groove. Interior silicon oil reservoir 2 solidifies the back and coats outer silicon oil reservoir 3 again, can improve curing effect so that interior silicon oil reservoir 2 part solidifies earlier in the cutting, and thick silicon oil reservoir curing effect is poor when avoiding once coating the silicon oil reservoir, leads to ultralight silicon oil reservoir from the type force not enough with substrate 1's bonding strength, and the design of cutting loses the condition appearance of effect. The secondarily coated outer silicone oil layer 3 can be sufficiently combined with the inner silicone oil layer 2 in a subsequent re-curing process, and the characteristic of ultra-light release force is retained.
Further, the engraved groove is formed by laser engraving. The grooves are arranged in matrix on the surface of the substrate 1. The depth of the groove is controlled by controlling the carving power during laser carving.
Furthermore, each notch comprises a shallow groove 4 and a deep groove 5, the depth of the deep groove 5 is greater than that of the shallow groove 4, all the deep grooves 5 are located on the same side of the corresponding shallow grooves 4, and the shallow grooves 4 are communicated with the deep grooves 5. The shallow grooves 4 and the deep grooves 5 are communicated to form the engraved grooves, so that the surface area of the base material 1 can be further increased. Meanwhile, the curing effect of the inner silicon oil layer 2 can be improved, and the influence on the inner silicon oil layer 2 during secondary curing is reduced.
Further, the outer silicon oil layer 3 and the inner silicon oil layer 2 have the same components. The inner silicon oil layer 2 and the outer silicon oil layer 3 are both silicon oil with ultra-light release force.
Example 2
As shown in figure 1, a super light is from type membrane of type power, including substrate 1 and the silicon oil layer of coating on substrate 1, the one side that is used for coating the silicon oil layer on substrate 1 is equipped with the grooving that a plurality of even intervals set up, the silicon oil layer is including interior silicon oil layer 2 and outer silicon oil layer 3, and interior silicon oil layer 2 is full of the grooving and covers substrate 1 surface, and outer silicon oil layer 3 covers the surface at inner strata high viscosity silicon oil layer 2 through the mode of secondary coating after interior silicon oil layer 2 solidifies. The surface area of the substrate 1 is increased by utilizing the groove, so that the contact area of the inner silicon oil layer 2 and the substrate 1 is greatly increased, and meanwhile, the cured inner silicon oil layer 2 can form larger binding force with the substrate 1 in the groove. The outer silicon oil layer 3 is coated after the inner silicon oil layer 2 is cured, so that the inner silicon oil layer 2 is cured in the notch groove, the curing effect is improved, the thick silicon oil layer curing effect is poor when the silicon oil layer is coated once, the silicon oil layer with the ultra-light release force is insufficient in the bonding strength with the substrate 1, and the condition that the notch groove is not designed to be acted appears. The secondarily coated outer silicone oil layer 3 can be sufficiently combined with the inner silicone oil layer 2 in a subsequent re-curing process, and the characteristic of ultra-light release force is maintained.
Further, the engraved groove is formed by laser engraving. The grooves are arranged in a matrix on the surface of the substrate 1. The depth of the groove is controlled by controlling the engraving power during laser engraving.
Furthermore, each notch comprises a shallow groove 4 and a deep groove 5, the depth of the deep groove 5 is greater than that of the shallow groove 4, all the deep grooves 5 are located on the same side of the corresponding shallow grooves 4, and the shallow grooves 4 are communicated with the deep grooves 5. The shallow grooves 4 and the deep grooves 5 are communicated to form the engraved grooves, so that the surface area of the base material 1 can be further increased. Meanwhile, the curing effect of the inner silicon oil layer 2 can be improved, and the influence on the inner silicon oil layer 2 during secondary curing is reduced.
Further, the release force of the outer silicon oil layer 3 is smaller than that of the inner silicon oil layer 2. Therefore, the inner silicon oil layer 2 can be prepared by adopting common silicone oil with common release force, and the bonding strength of the inner silicon oil layer 2 and the substrate 1 is improved.
Further, the outer silicone oil layer comprises 330 silicone oil, and the inner silicone oil layer comprises 240 silicone oil. The rest is the common composition of the release layer with ultra-light release force, such as the light release force additive of 7200 type.
