Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to double -sided adhesive tape technical field more specifically, the utility model relates to a kind of flame-retardant double -sided adhesive tape. BACKGROUND
[0002] Double -sided adhesive tape is made of paper, cloth, plastic film, elastomer type pressure sensitive adhesive or resin type pressure sensitive adhesive into roll-shaped adhesive tape, widely used in leather, plaque, stationery, electronics, car trim fixed, shoemaking, papermaking, handicraft pasting positioning etc.
[0003] Although double -sided adhesive tape in prior art can be used normally, there are still many shortcomings in actual use, such as the flame-retardant effect of double -sided adhesive tape in prior art is not good enough, when encountering open fire, it cannot be used as combustion-supporting material, and even it can become combustion-supporting material, which cannot stop the spread of fire, so that the actual use effect of double -sided adhesive tape in prior art is not good enough. SUMMARY
[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of the utility model provide a kind of flame-retardant double -sided adhesive tape, by being equipped with side edge adhesive layer, coarse asbestos core and fine asbestos core and other structures, the flame-retardant effect of the utility model is good, when encountering open fire, it can effectively flame-retardant, avoid the spread of fire, so that the actual use effect of the utility model is good, to solve the problems raised in the above background art.
[0005] To achieve the above object, the utility model provides the following technical scheme: a kind of flame-retardant double -sided adhesive tape, including substrate layer, the top and bottom of substrate layer are all adhesively connected with middle adhesive layer, the two sides of middle adhesive layer are all provided with side edge adhesive layer, side edge adhesive layer is adhesively connected on substrate layer, the same isolation paper layer is adhesively connected on middle adhesive layer and side edge adhesive layer, three groups of coarse asbestos cores are penetrated and arranged in substrate layer, three groups of fine asbestos cores are penetrated and arranged in side edge adhesive layer.
[0006] In a preferred embodiment, the number of coarse asbestos cores in each group is set to multiple.
[0007] In a preferred embodiment, the number of fine asbestos cores in each group is set to multiple.
[0008] In a preferred embodiment, the two groups of coarse asbestos cores adjacent to each other are staggered.
[0009] In a preferred embodiment, the two groups of fine asbestos cores of the necklace are staggered.
[0010] Technical effects and advantages of the utility model:
[0011] The utility model discloses a side edge viscose layer, coarse asbestos core and fine asbestos core etc. structure is set up, make the utility model discloses the flame -retardant effect is better, when meeting the open fire, can effectively flame -retardant, avoid the fire spread, make the actual use effect of the utility model discloses good.

[0016] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative work belong to the range of protection of the utility model.
[0017] As shown in the attached Figures 1-3 The utility model discloses a kind of flame-retardant double-faced tapes, including base material layer 1, the top and bottom of the base material layer 1 are all adhesively provided with intermediate viscose layer 2, the two sides of the intermediate viscose layer 2 are all provided with side edge viscose layer 3, the side edge viscose layer 3 is adhesively arranged on base material layer 1, the same isolation paper layer 4 is adhesively arranged on the intermediate viscose layer 2 and side edge viscose layer 3, three groups of coarse asbestos core 5 are penetrated and arranged in the inside of the base material layer 1, three groups of fine asbestos core 6 are penetrated and arranged in the inside of the side edge viscose layer 3.
[0018] The number of each group of the coarse asbestos core 5 is set to multiple.
