Abstract
The utility model discloses a polypropylene protection film, include polypropylene material layer and the pressure sensitive adhesive layer who locates polypropylene material layer below, polypropylene material layer includes the superficial layer and inboard internal surface layer in the outside. The utility model discloses having goodly in air discharge performance and viscidity suitability, having reduced the control degree of difficulty of production and use, the polypropylene material makes the holistic temperature resistance behavior of protection film stronger.
Description
Technical field
The utility model relates to electronics and optical field, relates to the polypropylene diaphragm of a kind of electronics and the use of optical field components and parts specifically.
Background technology
At present, the diaphragm of the diaphragm used in electronics and optical component processing and manufacturing process normally acrylic (pressure-sensitive acrylate) pressure sensitive adhesive coating, viscosity adaptability and poor from venting quality, the difficulty controlled in production and use procedure is large.Pressure-sensitive acrylate monomer extensively selective, cheap, production technology is simple, the adhesive of high comprehensive performance, but due to the polarity of short carbon chain monomer strong, surface wettability is bad, coating weight is large on the impact of viscosity, and it is large that process controls difficulty.And the reactivity of Long carbon chain monomer is low, copolymerizable is bad, and level of residual monomers is large and volatility is low, and residue in manufactured goods can be caused the pollution of protected.As for organic-silicon-modified acrylic pressure sensitive adhesive, although venting quality has greatly improved, the pollution on protected surface is one all the time and is difficult to overcome problem.
Above-mentioned defect, is worth solving.
Summary of the invention
In order to overcome the deficiency of existing technology, the utility model provides a kind of polypropylene diaphragm.
Technical solutions of the utility model are as described below:
A kind of polypropylene diaphragm, is characterized in that, comprises polypropylene-base sheet material layers and coats the pressure-sensitive adhesive layer below described polypropylene-base sheet material layers, and described polypropylene-base sheet material layers comprises the superficial layer in outside and the interior surface layers of inner side.
Further, described superficial layer is the heatproof superficial layer through coextrusion casting process, and described interior surface layers is the polyolefin elastomer interior surface layers crossed through sided corona treatment.
Further, described pressure-sensitive adhesive layer is polyurethane pressure sensitive glue-line.
Further, the thickness of described polypropylene-base sheet material layers is 30-100 micron.
Further, in described polypropylene-base sheet material layers, the thickness of described superficial layer is 21-95 micron, and the thickness of described interior surface layers is 5-20 micron.
Further, the thickness of described superficial layer is 35 microns.
Further, the thickness of described interior surface layers is 5 microns.
Further, the thickness of described pressure-sensitive adhesive layer is 5-20 micron.
Further, the thickness of described pressure-sensitive adhesive layer is 10 microns.
According to the utility model of said structure, its beneficial effect is, the utility model has more excellent in exhaust performance, and the thickness of pressure-sensitive adhesive layer is little on the impact of viscosity when making to change in the larger context, improve the viscosity applicability of diaphragm, reduce the control difficulty of production and use procedure; Polypropylene base makes the heat resistance of diaphragm entirety stronger; The utility model can also reduce residue to the pollution of protected.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In the drawings, 1, superficial layer; 2, interior surface layers; 3, pressure-sensitive adhesive layer.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is conducted further description:
As shown in Figure 1, a kind of polypropylene diaphragm, comprises polypropylene-base sheet material layers and coats the pressure-sensitive adhesive layer 3 below polypropylene-base sheet material layers, and polypropylene-base sheet material layers comprises the superficial layer 1 in outside and the interior surface layers 2 of inner side.
Superficial layer 1 adopts multi-layer co-extruded casting machine, and by casting technique, it is heatproof superficial layer, and interior surface layers 2 is polyolefin elastomer (POE) interior surface layers crossed through sided corona treatment.Pressure-sensitive adhesive layer 3 is polyurethane pressure sensitive glue-line.
The thickness of polypropylene-base sheet material layers is 30-100 micron, and wherein, the thickness of superficial layer 1 is 21-95 micron, and the thickness of interior surface layers 2 is 5-20 micron.Preferably, the thickness of superficial layer 1 is 35 microns, and the thickness of interior surface layers 2 is 5 microns.
The thickness of pressure-sensitive adhesive layer 3 is 5-20 micron.Preferably, the thickness of pressure-sensitive adhesive layer 3 is 10 microns.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to the utility model claims.
By reference to the accompanying drawings exemplary description is carried out to the utility model patent above; the realization of obvious the utility model patent is not subject to the restrictions described above; as long as have employed the various improvement that method is conceived and technical scheme is carried out of the utility model patent; or the design of the utility model patent and technical scheme directly applied to other occasion, all in protection domain of the present utility model without to improve.
