Description
The present invention relates to a polyolefin tape and a method of manufacturing the same. More particularly, the present invention relates to a polyolefin tape and a method of manufacturing the polyolefin tape, and more particularly to a polyolefin tape Tape and a manufacturing method thereof.
As the adhesive tape, a pressure-sensitive adhesive sheet has been developed and used as a base layer of a soft vinyl chloride-based sheet to which a plasticizer is added to a vinyl chloride resin, and a pressure-sensitive adhesive is applied thereon. Examples of the application of such a PVC (polyvinyl chloride) -type adhesive sheet include a surface protecting adhesive sheet, a pressure-sensitive masking sheet for masking, and a marking sheet.
As described above, the pressure-sensitive adhesive tape comprising the substrate for pressure-sensitive adhesive tapes produced from PVC is excellent in mechanical properties, in particular, flexibility and stretchability, flame resistance, resistance to thermal deformation and electrical insulating properties. According to such an economical aspect, the adhesive tape can be used for electric equipment used in fields such as automobiles, trains, buses, etc., aircrafts, ships, houses, factories, and the like, especially electric wiring devices for automobiles (Wiring Harness, And is widely used as an insulating tape for a semiconductor device.
That is, the adhesive tape wrapping around the wire device used for electric wire for automobiles, coils for electric appliances, electric wire and the like must have high flame resistance (oxygen index of 25% or more) and high resistance to thermal deformation. In order to satisfy these requirements, an adhesive tape using PVC as a base material is widely used.
However, since the thermal stability of PVC is lower than that of other plastic resins, oxidation occurs rapidly when pyrolysis is performed, and plasticizers added to soften PVC are deteriorated and used in high heat resistant parts. In other words, conventional PVC has a flame retardant property due to chlorine (Cl), which is advantageous for securing the flame resistance of the product itself, but polyolefin, which is an alternative resin, has no substance that imparts flame resistance to itself, It is difficult to secure flame retardancy.
Also, due to recent environmental problems, there is a move to reduce the use of PVC and replace it with a substance that causes less environmental burden. This is because PVC is presumed to generate toxic gases such as dioxins and chlorine gas upon combustion. In order to replace PVC, it has been considered to use a polyolefin resin as a substrate, since it does not generate toxic gases such as dioxin or chlorine gas upon combustion.
Examples of such techniques are described in documents 1 and 2 below.
