Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the field of adhesives, in particular to a preparation method of an adhesive tape for process protection.
[ background of the invention ]
With the rapid development of electronic products, an all-metal integrated body is one of the most popular elements at present. The all-metal integrated machine body is subjected to a series of surface treatments in the processing process, such as a series of complex processes of polishing, electroplating, spraying, etching, laser and the like. These processes require a material to protect them from scratching and damage at other non-processing locations.
At present, the non-processing part is generally protected by using protective films such as a PET protective film, a PE protective film, a PVC protective film, and an OPP protective film. However, the PET protective film cannot be well adhered to corners and radian parts due to the hardness of the base material PET, and cannot achieve effective process protection; although the base materials of the PE protective film, the PVC protective film and the OPP protective film are soft, due to the fact that the adhesive layer has pressure sensitivity, corners and radian parts cannot be perfectly attached in the attaching process, air bubbles are remained, and the air bubbles are marked and remained after the protective films are peeled off through a series of processes, so that the appearance and the yield of products are affected. Taking the shell of the apple phone as an example, the general protective film cannot be completely wrapped due to excessive corners and radians in the processing process of the inner side of the shell, so that the product yield is low.
In order to solve the above problems, the market is in urgent need to develop a new production process to obtain a process protection adhesive tape capable of wrapping corners and radian parts of a shell well.
[ summary of the invention ]
The invention aims to provide a preparation method of an adhesive tape, so as to obtain the adhesive tape for process protection, which can wrap corners and radians of a shell, and improve the process protection effect. The technical scheme of the invention is as follows:
the preparation method of the adhesive tape is characterized by comprising the following steps: coating the thermosensitive adhesive on a first release film, and drying to form a release film layer and a thermosensitive adhesive layer; coating the pressure-sensitive adhesive on a second release film to form a pressure-sensitive adhesive layer adhered to the second release film, drying, and adhering the substrate and the pressure-sensitive adhesive layer; and (3) stripping the second release film from the pressure-sensitive adhesive layer, and simultaneously laminating the second release film with the heat-sensitive adhesive layer to form the adhesive tape with the release film layer, the heat-sensitive adhesive layer, the pressure-sensitive adhesive layer and the substrate layer laminated in sequence. The method can obtain the adhesive tape which can reduce bubbles or marks generated when the shell is wrapped, and can improve the yield by 10-30% compared with the prior process of the integrated shell; the thermal sensitive adhesive layer has no viscosity at the initial stage of bonding, and the peeling strength of the thermal sensitive adhesive layer is improved after heating, thereby achieving the fixing and protecting functions.
Furthermore, the preparation method of the adhesive tape further comprises a rolling step, and in order to better fit different layers of materials, the adhesive tape is rolled in a roll shape, so that the storage positions of products can be reduced, and the adhesive tape is convenient to suspend.
Further, the preparation method of the adhesive tape also comprises a curing step, so that the adhesive layer is subjected to later-stage reaction, and the later-stage stability of the adhesive is ensured.
Furthermore, the thickness of the pressure-sensitive adhesive and/or the heat-sensitive adhesive is 5-20 μm, the adhesive force is low after the temperature is less than 5 μm, the pressure-sensitive adhesive is easy to release, and the adhesive force is too high after the temperature is more than 20 μm, so that the residual adhesive is polluted after being stripped, and even the pressure-sensitive adhesive is difficult to strip.
Furthermore, the coating speed of the pressure-sensitive adhesive and/or the heat-sensitive adhesive is 10-40m/min, the speed efficiency lower than 10m/min is lower, the production cost is increased, and the drying speed higher than 40m/min is incomplete, so that the performance of the product is poor.
Further, the pressure-sensitive adhesive and/or the heat-sensitive adhesive are dried at 40-120 deg.C for 1-8 min. Because the drying oven is generally about 30m, the drying time can be adjusted according to the change of the speed, and the drying state of the adhesive can be met in the interval, and meanwhile, the production efficiency and the cost can be controlled.
Furthermore, the pressure-sensitive adhesive is composed of one or more of polyurethane pressure-sensitive adhesive, acrylic acid pressure-sensitive adhesive and rubber pressure-sensitive adhesive, the pressure-sensitive adhesive has stable temperature and humidity resistance and good adhesion to materials, and can be easily bonded with the materials under proper pressure.
Further, the thermosensitive adhesive is prepared from the following components in parts by weight: 40-50 parts of styrene-butadiene-styrene rubber elastomer, 50-60 parts of terpene and/or rosin tackifying resin, 0-5 parts of softener and 0-10 parts of antioxidant. The thermosensitive adhesive prepared by the formula is sensitive to temperature, can achieve the fixing and protecting effect under certain heat, can be easily peeled off after being cooled, and is convenient to use and operate.
Further, the heat-sensitive adhesive is prepared by the following method: the rubber elastomer and the tackifying resin are dissolved to form rubber slurry and resin slurry, the rubber solution and the resin solution are added into a stirring device, and a softener, a plasticizer and an antioxidant are added into the stirring device to be dissolved and stirred into uniform and stable viscous liquid, and various materials can be better dissolved by the adding mode.
Furthermore, the solid content of the rubber solution and/or the resin solution is 40-60%, the viscosity and the solid content in the interval are more suitable for coating, the leveling property is better, and the adjustable range of the thickness interval is wide.
The invention has the following beneficial technical effects:
the invention can obtain the adhesive tape which takes soft PE, PVC, PBT, polyester urethane, PP, TPU and other materials as base materials and is provided with a heat-sensitive layer and a pressure-sensitive layer at the same time, the adhesive tape is not sticky in the initial stage of bonding, the materials are pasted on the inner side of the shell through vacuum adsorption, then the heating is carried out, when the temperature is raised to the softening temperature of the base materials, the base materials begin to be soft, the colloid is still not sticky, at the moment, the soft base materials and the adhesive layer are in good contact with corners and radian parts through the vacuum adsorption, the colloid begins to be sticky through continuous heating, the adhesive tape can be well pasted on the inner side of the shell after the temperature is reduced, thereby avoiding scratching or damaging other parts in the subsequent process, compared with the prior process: the wrapping and protecting area is improved by 10-25%, the incidence rate of attaching bubbles is reduced by 15-40%, the process difficulty is reduced, and the yield can be improved by 10-30%; (ii) a The invention is prepared by adopting a two-layer laminating mode, thereby avoiding the problem of residual glue after the thermosensitive adhesive layer is heated, laminated, cooled and stripped; the adhesive force between the thermosensitive adhesive and the base material is improved through the pressure-sensitive adhesive layer, the problem that the initial thermosensitive adhesive cannot be attached to the base material is solved, and the adhesive is free of degumming and separation phenomena in the using process; the invention adopts a double-layer laminating process, and the structure of laminating the pressure-sensitive adhesive layer and the heat-sensitive adhesive layer has the advantages of simple production process, high yield and lower cost.
