[0028] Embodiment
[0029] As Figure 1 and Figure 2 shown, a flame-retardant electrostatic cotton proposed by the present utility model includes: a base layer 1, and the base layer 1 is made of polyester fiber material, having good mechanical properties and heat resistance. An antistatic layer 2 is adhesively provided on the upper side of the base layer 1, and a protective layer 3 is provided outside the antistatic layer 2, and the protective layer 3 is polyurethane or epoxy resin, which can provide good wear resistance and scratch resistance, and improve the service life of the electrostatic cotton; a flame-retardant layer 4 adhesively provided inside the base layer 1 for flame retardancy, and an adhesive layer 5 is provided inside the flame-retardant layer 4, and the adhesive layer 5 is polyimide glue, a high-performance adhesive with high temperature resistance and chemical resistance, which has excellent thermal stability and chemical stability; a heat dissipation layer 7 provided between the flame-retardant layer 4 and the adhesive layer 5 for improving heat dissipation, facilitating the rapid dissipation of heat from the side and reducing the ignition point of the electrostatic cotton.
[0030] As Figure 2 andFigure 3 As shown, the flame retardant layer 4 includes a first fireproof layer 41 and a second fireproof layer 42 arranged in parallel, and the first fireproof layer 41 and the second fireproof layer 42 are bonded by a modified silane adhesive. The modified silane adhesive has excellent high-temperature resistance and flame retardant properties, and at the same time has high bonding strength and good chemical resistance. A plurality of card slots 43 are formed on the bottom surface of the first fireproof layer 41, and the plurality of card slots 43 are arranged horizontally at equal intervals. A card strip 44 corresponding to the card slots 43 is fixedly arranged on the upper surface of the second fireproof layer 42, and the card strip 44 is clamped with the card slots 43, which can enable the first fireproof layer 41 and the second fireproof layer 42 to be stably clamped with each other, prevent separation when encountering a fire source, reduce air and the combustion surface, and the tight combination can form a more effective flame retardant barrier, making it more difficult to burn when encountering a fire source and improving the safety performance of the product.
[0031] As Figure 2 and Figure 4 shown, the heat dissipation layer 7 includes a diffusion layer 71. A plurality of first heat dissipation holes 72 are formed on one side of the diffusion layer 71, and the plurality of second fireproof layers 42 are arranged horizontally at equal intervals. A plurality of second heat dissipation holes 73 corresponding to the first heat dissipation holes 72 are formed on the bottom surface of the diffusion layer 71, and the second heat dissipation holes 73 are communicated with the first heat dissipation holes 72, which can quickly absorb and disperse the surface temperature, slow down the ignition time of the electrostatic cotton, and thus extend the combustion start time of the material.
[0032] Furthermore, the antistatic layer 2 is made of a blend of cotton fibers and wire fibers, and the wire fibers are carbon fibers or graphene fibers, both of which have excellent electrical conductivity and can effectively reduce the accumulation of static electricity, thereby improving the antistatic effect.
[0033] Secondly, the first fireproof layer 41 and the second fireproof layer 42 are made of polyether ether ketone material, which has high thermal stability and can be used for a long time in a high-temperature environment without deformation. Therefore, it can still maintain good flame retardant performance under high-temperature conditions.
[0034] Furthermore, the diffusion layer 71 is made of polytetrafluoroethylene material, which can withstand a very high temperature, which enables it to maintain stable working performance in a high-temperature environment, ensuring that the first heat dissipation holes 72 and the second heat dissipation holes 73 do not deform when encountering high temperature, thereby improving the stability of heat dissipation.
[0035] In addition, the first fireproof layer 41 and the second fireproof layer 42 have the same thickness and are between 0.2 mm and 0.5 mm. The relatively thick first fireproof layer 41 and second fireproof layer 42 can improve the thermal stability of the material and are not easily melted or deformed in a high-temperature environment.
[0036] Finally, a release layer 6 is arranged inside the adhesive layer 5, which helps to extend the service life of the adhesive layer 5 by isolating harmful substances and environmental impacts from the outside.
[0037] The working principle of this embodiment is as follows: During use, multiple card slots 43 and card strips 44 are engaged with each other, and the first fireproof layer 41 and the second fireproof layer 42 are connected to each other with the cooperation of modified silane glue. After encountering a fire source, the card slots 43 and the card strips 44 are tightly engaged with each other, preventing the separation of the first fireproof layer 41 and the second fireproof layer 42, reducing air circulation and the combustion surface. The tight combination can form a more effective fireproof barrier, making it more difficult to burn when encountering a fire source and improving the safety performance of the product.
[0038] Furthermore, through the wire fibers inside the antistatic layer 2, static electricity can be conducted out, effectively reducing the accumulation of static electricity, thereby improving the antistatic effect. And through the diffusion layer 71, after the static cotton encounters a fire source, the first heat dissipation holes 72 and the second heat dissipation holes 73 can quickly absorb and disperse the surface temperature, slowing down the ignition time of the static cotton, thereby prolonging the ignition start time of the material.
[0039] The above specific embodiments are merely several alternative embodiments of the present utility model. Based on the technical solution of the present utility model and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
