Description

TECHNICAL FIELD

[0001] The utility model relates to the field of release paper, concretely to a kind of anti-sticking release paper. BACKGROUND

[0002] Release paper, also known as silicone oil paper and anti-sticking paper, mainly serves to isolate objects with stickiness. The release paper in double-sided tape is coated with silicone oil on both sides. When the release paper is peeled off from the double-sided tape base material, the contact area between the traditional release paper and fingers is small due to its thin thickness, making it inconvenient to peel off from the double-sided tape base material. Moreover, since the double-sided tape is stored in a roll shape, the release paper may curl when peeled off from the double-sided tape base material, resulting in re-sticking to the base material.

[0003] Therefore, the utility model provides an anti-sticking release paper to alleviate the above technical problems. SUMMARY

[0004] The utility model aims to provide an anti-sticking release paper to overcome the above-mentioned defects in the prior art.

[0005] According to the anti-sticking release paper of the utility model, the first release paper and the second release paper form a double-layer structure after being bonded, and a plurality of support strips are fixed between the first release paper and the second release paper along the length direction of the first release paper.

[0006] Through the above technical solution, the double-layer structure formed by the first release paper and the second release paper increases the thickness of the release paper, which increases the contact area between the edge of the release paper and the fingers, making it easier for the fingers to peel the release paper off the base material. Meanwhile, the support strips increase the bending resistance of the release paper and reduce the occurrence of re-sticking after peeling off the base material.

[0007] Further, the upper surface of the first release paper and the lower surface of the second release paper are both coated with a layer of silicone oil layer, and the lower surface of the first release paper and the upper surface of the second release paper are bonded by an adhesive.

[0008] Through the above technical solution, the adhesive is used to bond the first release paper and the second release paper, making the double-layer structure formed by the two more stable during use.

[0009] Further, the second release paper is provided with a cavity structure that reduces its adhesion to the base material, and the lower surface of the first release paper is coated with a silicone oil layer at the position of the cavity structure in the second release paper.

[0010] Through the above technical solution, the adhesion between the second release paper and the base material is reduced, making it easier to peel the second release paper off the base material.

[0011] Further, the cavity structure is a strip-shaped through groove arranged along the length direction of the second release paper, and the strip-shaped through groove is arranged between two support strips.

[0012] Through the technical scheme, the strip-shaped through groove arranged along the length direction of the second release paper can reduce the contact area between the second release paper and the substrate, thereby reducing the adhesion between the second release paper and the substrate.

[0013] Further, the cavity structure is a plurality of block-shaped through grooves arranged equidistantly along the length direction of the second release paper, and the block-shaped through grooves are arranged between two support strips.

[0014] Through the technical scheme, the plurality of block-shaped through grooves arranged along the length direction of the second release paper can reduce the contact area between the second release paper and the substrate, thereby reducing the adhesion between the second release paper and the substrate, and if the second release paper is disconnected at the interval between adjacent block-shaped through grooves, the solid part of the second release paper can still reduce the dust entering the block-shaped through groove.

[0015] Further, the first release paper forms a protruding part protruding upward on the upper side of the support strip.

[0016] Through the technical scheme, the protruding part protruding upward further increases the contact area between the release paper and the fingers, so as to facilitate the fingers to peel the release paper from the substrate.

[0017] Further, the support strip is a strip-shaped thin film made of a high polymer.

[0018] Through the technical scheme, after the support strip is torn and disconnected, the fracture part is stretched and deformed to protrude out of the first release paper and the second release paper, so that the stretched part of the protruding part can be pinched when the release paper is peeled next time, further facilitating the separation of the release paper and the substrate.

[0019] The beneficial effects of the utility model are that: the double-layer structure formed by the first release paper and the second release paper increases the thickness of the release paper, so as to increase the contact area between the edge of the release paper and the fingers, thereby making the fingers more easily peel the release paper from the substrate, since the support strip has plasticity, the plasticity of the support strip is used to support, increase the bending resistance of the release paper, reduce the re-sticking of the release paper after being peeled from the substrate, and after the support strip is torn and disconnected, the fracture part is stretched and deformed, so that the stretched part of the protruding part can be pinched when the release paper is peeled next time, further facilitating the separation of the release paper and the substrate.

[0027] First embodiment:

[0028] Referring to Figures 1-2 ​The utility model provides a kind of anti-sticking release paper, including first release paper 11 and second release paper 14, second release paper 14 is adhered on substrate, first release paper 11 and second release paper 14 are adhered after forming double-layer structure, first release paper 11 lower surface and second release paper 14 upper surface are not coated with silicone oil layer, first release paper 11 and second release paper 14 between fixed with several support strips 13 being set along the length direction of first release paper 11, first release paper 11 upper surface and second release paper 14 lower surface are coated with a layer of silicone oil layer, first release paper 11 lower surface and second release paper 14 upper surface between by adhesive bonding, second release paper 14 is internally provided with cavity structure for reducing its adhesion with substrate, the position of first release paper 11 lower surface at the cavity structure in second release paper 14 is coated with silicone oil layer, cavity structure is the strip-shaped through slot 15 being set along the length direction of second release paper 14, after strip-shaped through slot 15 is set on second release paper 14, a layer of adhesive is coated on the surface without silicone oil layer, after support strip 13 is attached on second release paper 14 and is located in the both sides of strip-shaped through slot 15, the surface without silicone oil layer of first release paper 11 is attached with the surface coated with adhesive of second release paper 14, and by pressure, the both are extruded and bonded, after the both are bonded, the lower surface of second release paper 14, the upper surface of first release paper 11 and the part of first release paper 11 lower surface in strip-shaped through slot 15 are coated with silicone oil, strip-shaped through slot 15 is set between two support strips 13, first release paper 11 forms the bulge 12 that is upwards on the upside of support strip 13, and support strip 13 is the strip-shaped of high molecular polymer film.

[0029] In use, the user abuts the finger with one end of the release paper, due to the double-layer structure of the release paper and the convex structure of the bulge 12, the contact area with the finger is increased, the release paper is easily peeled off from the substrate by the finger, and the strip-shaped through slot 15 reduces the adhesion between the second release paper 14 and the substrate, so that the second release paper 14 is more easily peeled off from the substrate, and the support of the first release paper 11 reduces the curling of the release paper, and reduces the re-sticking of the release paper.

[0030] When the release paper is disconnected, the support strip 13 made of high molecular polymer has certain flexibility in the form of film, can be deformed when stretched, has certain hardness, can resist certain external force, so that the release paper can reduce the bending after being peeled off from the substrate, and reduces the re-sticking, the support strip 13 is stretched by tearing, so as to stretch out of the first release paper 11 and the second release paper 14, so that the finger can pinch the stretched and deformed part of the support strip when the release paper is used again.
