New description: [New technical field] This creation is about the back film structure of environmentally-friendly adhesive tape, especially the back film structure of environmentally-friendly electrical insulating tape without polyvinyl chloride. [Prior Art] Polyvinyl chloride (PVC) has been widely used as a backing material for various electrical insulating tapes because of its flame and heat resistance properties and its easy processing properties. However, with the awareness of environmental protection, the world's advanced countries have banned the use of high-grade pollutant materials, and actively develop environmentally friendly materials that are environmentally friendly. - Electrically insulating tape containing PVC backing, which contains halogenated knives, produces toxic substances after incineration, and is difficult to recycle. In many countries, electrical insulating tapes containing PVC components have been banned. In order to meet the requirements of environmental protection, relevant manufacturers have invested in the research of environmentally-friendly electrical insulating tape, and developed a variety of tape backing materials without PVC components. In order to make these environmentally-friendly electrical insulating tape backing films have the characteristics of elasticity, toughness, touch, and flame and heat resistance of PVC tape backing film, f often use flame retardant, filler, processing aid, plasticizing. Additives such as agents, dyes, pigments, antioxidants, and antistatic agents. For example, the US Patent No. 5,284,889 discloses an electrical insulating rubber consisting of ethylene vinyl acetate copolymerization = VA) and ethylene propylene diene rubber egg pDM. The tape back film includes (4) Adding components such as a coupling agent and a flame retardant. Further, U.S. Patent No. 6,376,068 discloses an insulating protective tape composed of a polyolefin and an EPDM, which also contains an additive component such as a pigment, an antioxidant, and an antistatic agent. 19566 5 M304534 The Republic of China Publication No. I 241321 discloses a backing film and an electrically insulating tape. For example, the i-milk insulating tape includes a backing film 100 and is coated on the back: one: the surface of the electrical insulating rubber is connected to the surface of the moon, and the back film is made of polyethylene and ethylene propylene diene rubber. Adding component 106 to the film also includes a filler and a processing aid. The additive component 106 in the backing film of the tape is not stably present in the back film of the tape = internal, and sometimes diffused and transferred to the surface of the back film structure. For example, the additive component in the second film, the backing film of the second film, 〇 6 diffusion to the back film and: 2: % '1〇6a' in the figure will cause the viscosity of the adhesive layer 200. On both sides, when the tape is stored in a rewinding manner, the inner tape back film ι: square plus ingredients 106 diffuses to the upper surface of the backing film, such as the surface characteristics of the backing film, and b, it will change the adhesive tape adjacent to the outer side of the adhesive tape colloidal residue 20〇a, resulting in the deterioration of the adhesive property of the tape. 200 rabbit students therefore 'requires an environmentally-friendly electrical insulating tape that does not increase the environmental burden of gel. ^, Permitted %疋 [new content] The main purpose of this creation is to provide a tape back film structure. The purpose is to provide a tape back film structure which can be added to the surface by adding ingredients. "...Tian Electric is also aiming to provide a structure which can avoid the deterioration of the glue, and the d-face 2 creation provides a back film knot of the environmental protection tape. Surface and opposite lower surface And forming 19566 ^ 6 M304534 on the upper and lower surfaces of the substrate, respectively, the upper layer of the substrate is formed with an isolated sound due to the underlying surface of the adhesive film of the present invention, and the additive component can be separated by the θ The blood inside the soil will be in the cylinder structure, and will not move to the surface of the back film structure, and the ::: will expand the creation also provides a use of the cover;嫌 ^ 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住 住The insulating layer is formed, and the layer and the backing film structure are 妒f妒力苴2, and the internal addition component of the rubber gong is effective for m, and the soil is not internally diffused and transferred to the back of the tape back sheet. The surface characteristics of the membrane structure lead to the deterioration of the gelatinity. The surface of the moon membrane is changed. [Embodiment] The following is a specific implementation of the characteristics and effects of the creation. Created an environmentally friendly tape backing structure. The two film structure (10) includes a substrate 1〇2, which has an upper surface 1〇24 opposite to the surface Na; and is formed on the upper and lower surfaces of the substrate ==〇4a, which is difficult. Since the substrate of the eco-friendly tape back film structure is The tape back film has an excellent similarity to the general polyvinyl chloride back film; = the characteristics required for the electrical insulating tape, the US material heart material 02 further has an internal added knife 106. The added component may be a filler such as a dioxide stone Xi, titanium dioxide, carbon gorge, carbon _, sulfur axis, barium sulfate, and (four) Shao. Processing aids, such as mold release agents, coupling agents, and lubricants; pigments; dyes; stabilizers; plasticizers; Additives; Antioxidant; and additives such as bismuth. 7 19566 ' M304534 ' The tape of the creation of the film is made of 甘 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , Add ingredients to the interior of the coffin. The thickness of the substrate is preferably between 1: 5 and: 曰, and the system is in the range of 1:8 to 2; and the second and the second is between 0.02 and 〇3 mm f η ~, ▼ months between the thickness of the structure. Between .3_ is preferably between 〇 and 〇.15mm. The two-layer structure is designed to change the surface of the back film structure (4) by the surface of the backing film. Ξ = effectively reduces the situation of gelatinous deterioration. The pure tape (4) of the other side also has the test results of the elongation class. As shown in Fig. 4, the tensile strength of the film and the replacement of the traditional pvr^b β 囷 are not, so the tape back film of the creation can be PVC. The film is used to make environmentally friendly electrical insulating tape. The sound map %t diagram is a first specific example of the electrical insulating tape of the present invention.
