Description
Technical Field
The invention relates to the field of flame-retardant adhesive tapes, in particular to a PI flame-retardant grid single-sided adhesive tape.
Background
Most mobile phones in the market at present adopt the rear cover of the glass body battery, but the relative cost is higher and the manufacturing process is more complicated, so more and more mobile phone manufacturers consider the rear cover of the polymer composite material plastic battery with lower use cost and simpler manufacturing process, the rear cover of the polymer composite material plastic battery can also achieve the beautiful effect of the glass material, and the whole body of the mobile phone body can be lighter and thinner. However, the plastic battery back cover using the polymer composite material needs to be faced with the problem that the plastic back cover is easily burned, and therefore, a flame retardant tape needs to be attached to the battery back cover.
The flame-retardant adhesive tape in the market mostly adopts PET as a base film, and a flame-retardant coating is coated on the base film, so that the flame-retardant effect is achieved. But is limited by the material quality of PET, the temperature for resisting flame is not high (120 ℃), and the material cannot resist high temperature for a long time.
Disclosure of Invention
Based on this, it is necessary to provide a PI flame-retardant grid single-sided tape, which includes a release film and a tape body adhered to the release film, wherein the tape body includes a 5 um-15 um pressure-sensitive adhesive layer, a 18 um-22 um PI base film layer and a 5-8 um light shielding layer, which are sequentially disposed, and the tape body is adhered to the release film through the pressure-sensitive adhesive layer; wherein, the light shield layer including use the coating process to coat in proper order on the PI base film 2 um-3 um's first polyurethane ink layer, 2 um-3 um's second polyurethane ink layer and 1 um-2 um's water-based matte oil layer.
In the invention, the release film is used for covering the sticky surface of the adhesive tape when the adhesive tape is not used, so that the situation that dust and other foreign matters are adhered to the sticky surface of the adhesive tape to influence the normal use of the adhesive tape is prevented; wherein, the thickness of sticky tape body keeps between 28um-45um for the sticky tape body has good flexibility, can laminate better on the surface of attached thing, thereby can make the sticky tape body have good subsides and cover the nature, and attached intensity.
In the invention, PI (polyimide) is used as the base layer of the adhesive tape body, and the PI has excellent high temperature resistance which can resist the high temperature of more than 400 ℃, so that the adhesive tape has excellent flame retardant property by using the PI as the base layer of the adhesive tape. The PI can be used in an environment of 300 ℃ for a long time without obvious melting point, so that the melting point can be avoided in an environment with higher temperature after the adhesive tape is adhered to the rear cover of the plastic battery, the adhesive tape can be ensured to cover the rear cover of the plastic battery all the time, and the adhesive tape can keep the preset flame-retardant effect for a long time; meanwhile, the water-based matte oil layer coated on the second polyurethane ink layer has good flame retardance and wear resistance, and can prevent the shading layer and the PI base film layer from being worn to influence the shading and flame-retardant effects of the adhesive tape.
In addition, the shading layer is used for enabling the adhesive tape to have the characteristic of full shading, the shading layer is formed by multiple times of coating, compared with one-time coating forming, the thickness of each time of coating is small, the uniformity of the coating layer can be well controlled, the overall uniformity of the coated shading layer can be ensured, the surface of the shading layer is prevented from generating concave-convex bad points, and the full shading performance of the shading layer can be prevented from being influenced by local depression.
Further, from the type membrane orientation one side surface of pressure sensitive adhesive layer is formed with a plurality of caves, it arranges to cave in to be the rectangular array form, form the sand grip between sunken, the mutual end to end connection of sand grip is latticed and arranges, and it is protruding to form the net that has the protruding structure of a plurality of vertically and horizontally staggered strips, just the net is protruding to extend outward from the surface of type membrane, the net is protruding to be embedded into pressure sensitive adhesive layer the latticed exhaust groove of surface formation of pressure sensitive adhesive layer, it is corresponding, the exhaust groove extends outward the surface of pressure sensitive adhesive layer.
Wherein, form latticed exhaust recess on the pressure-sensitive adhesive layer of adhesive tape from the net arch on the type membrane, when the adhesive tape used, the control between adhesive tape and the attached thing can be arranged away to the exhaust recess that forms on the adhesive tape to can avoid appearing the bubble between adhesive tape and attached thing, influence the paste firmness of adhesive tape.
Further, the width of the exhaust groove is 1.0 mm-1.5 mm.
The width of the exhaust groove is kept between 1.0mm and 1.5mm, so that when the adhesive tape is attached, the air between the adhesive tape and an attached object can smoothly flow out of the exhaust groove, the adhesive tape cannot be extruded due to insufficient air exhaust speed, and the bumps formed on the adhesive tape are deformed.
Further, the pressure-sensitive adhesive layer is an acrylic adhesive layer, and the acrylic adhesive layer comprises 99% -99.7% of acrylic adhesive and 0.3% -1% of curing agent.
Furthermore, the gaps between the exhaust grooves form bumps, and the transverse sectional area of each bump is 0.2-0.25 mm2。
WhereinSo that the transverse cross-sectional area of the bump is 0.2mm2—0.25mm2It is possible to ensure sufficient adhesion of the adhesive tape while forming the vent grooves in a lattice shape on the pressure-sensitive adhesive layer.
Furthermore, the bumps are square, the side length of each bump is 4.5 mm-5 mm, and the distance between every two adjacent bumps is 1.0 mm-1.5 mm.
The bumps are square, so that the adhesive strength of the adhesive tape is more uniformly distributed, and the situation that the adhesive tape is partially loosened can be avoided.
Furthermore, the exhaust grooves in the pressure-sensitive adhesive layer are formed by attaching the adhesive tape body to a release film with grid protrusions and then performing hot press forming.
The exhaust groove on the pressure-sensitive adhesive layer of the adhesive tape body can be formed when the adhesive tape is adhered to the release film, the pressure-sensitive adhesive layer does not need to be processed outwards, and the production efficiency of the adhesive tape can be effectively improved.
The principle and effect of the present invention will be further explained by combining the above technical scheme and the accompanying drawings:
in the invention, PI (polyimide) is adopted as the base layer of the adhesive tape body, the PI has excellent high temperature resistance and can resist the high temperature of more than 400 ℃, so that the adhesive tape has excellent flame retardant property by using the PI as the base layer of the adhesive tape, and the adhesive tape is used as the flame retardant adhesive tape of the rear cover of the plastic battery and is attached to the surface of the rear cover of the plastic battery, thereby effectively avoiding the combustion condition of the rear cover of the plastic battery caused by abnormal temperature rise of the battery. The PI can be used in an environment of 300 ℃ for a long time without obvious melting point, so that the melting point can be avoided in an environment with higher temperature after the adhesive tape is adhered to the rear cover of the plastic battery, the adhesive tape can be ensured to cover the rear cover of the plastic battery all the time, and the adhesive tape can keep the preset flame-retardant effect for a long time; meanwhile, the water-based matte oil layer coated on the second polyurethane ink layer has good flame retardance and wear resistance, and can prevent the shading layer and the PI base film layer from being worn to influence the shading and flame-retardant effects of the adhesive tape.
