Description

Technical Field

[0001] This utility model relates to the field of flame retardant masterbatch, and more specifically, to a high-impact ABS flame retardant masterbatch. Background Technology

[0002] ABS resin is widely used in electronics, automobiles, building materials and other fields due to its excellent comprehensive properties;

[0003] A search revealed an existing patent (publication number: CN220034369U) that discloses a bromine-antimony composite flame retardant masterbatch, comprising a main body, a coating layer on the surface of the main body, an outer flame retardant layer installed inside the main body, an anti-ultraviolet layer installed on one side of the outer flame retardant layer, an inner flame retardant layer installed at the end of the anti-ultraviolet layer away from the outer flame retardant layer, and a cold-resistant layer installed at the end of the inner flame retardant layer away from the anti-ultraviolet layer. The flame retardant masterbatch in this device ensures excellent flame retardant performance through the outer flame retardant layer, the inner flame retardant layer, and the coating layer. The anti-ultraviolet layer and the cold-resistant layer give the masterbatch not only super UV protection but also strong cold resistance, resulting in good flame retardant effect and wide applicability.

[0004] When existing high-impact ABS flame retardant masterbatches lack a middle layer support, the antibacterial coating is easily damaged under impact or friction. Furthermore, without an outer layer protection, ultraviolet rays directly destroy the molecular structure of the antibacterial agent, and water vapor penetration leads to hydrolysis of the matrix resin, resulting in certain limitations in its use. At the same time, the aforementioned cited patent documents do not propose any solutions to address the above problems.

[0005] Therefore, a high-impact ABS flame-retardant masterbatch is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a high-impact ABS flame-retardant masterbatch to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-impact ABS flame-retardant masterbatch, comprising a masterbatch body, an outer protective layer fixedly bonded to the inner side of the masterbatch body, the outer protective layer being a nano zinc oxide-acrylate coating, and an antibacterial coating provided on one side of the outer protective layer, the antibacterial coating being made of a quaternary ammonium salt compound material, and a middle reinforcing layer provided on the inner side of the antibacterial coating, the middle reinforcing layer being made of a nano cellulose-epoxy resin coating material.

[0008] Preferably, a flame-retardant reinforcing layer is provided on one side of the intermediate reinforcing layer, the flame-retardant reinforcing layer including a first reinforcing layer, the first reinforcing layer being made of a nano-montmorillonite-boron composite coating.

[0009] Preferably, a second reinforcing layer is provided on one side of the first reinforcing layer, and the second reinforcing layer is made of an aramid fiber-phosphate composite coating.

[0010] Preferably, a third reinforcing layer is provided inside the second reinforcing layer, and the third reinforcing layer is made of a carbon nanotube-aluminum hydroxide composite coating.

[0011] Preferably, an inner flame-retardant layer is provided on one side of the third reinforcing layer, and the inner flame-retardant layer is made of a nitrogen-phosphorus synergistic flame-retardant coating.

[0012] Preferably, a filler layer is provided on the inner side of the inner flame-retardant layer, and the filler layer is made of polyolefin material.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] Compared with existing technologies, this high-impact ABS flame-retardant masterbatch has an outer protective layer, an antibacterial coating, and a middle reinforcing layer. The middle reinforcing layer provides rigid support for the antibacterial coating, preventing the antibacterial coating from peeling off due to substrate deformation, thus maintaining the antibacterial rate at over 99% for a long time. At the same time, the outer protective coating isolates ultraviolet rays and moisture, preventing the antibacterial agent from oxidizing and decomposing, thereby extending the antibacterial effectiveness period and improving the practicality of the device to a certain extent.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] As attached Figures 1 to 3The high-impact ABS flame-retardant masterbatch shown includes a masterbatch body 1, an outer protective layer 2 fixedly bonded to the inner side of the masterbatch body 1, the outer protective layer 2 being a nano zinc oxide-acrylate coating, and an antibacterial coating 3 being provided on one side of the outer protective layer 2, the antibacterial coating 3 being made of quaternary ammonium salt compound material, and a middle reinforcing layer 4 being provided on the inner side of the antibacterial coating 3, the middle reinforcing layer 4 being made of nano cellulose-epoxy resin coating material.

[0021] Specifically: an outer protective layer 2 is provided, which has good ultraviolet blocking ability with an ultraviolet blocking rate of >95%, effectively blocking ultraviolet rays in sunlight and reducing the damage of ultraviolet rays to the internal structure of the material. An antibacterial coating 3 is provided, which contains antibacterial components such as quaternary ammonium salts, which can effectively inhibit the growth and reproduction of bacteria on the material surface by destroying the cell membrane of bacteria. At the same time, a middle reinforcing layer 4 is provided, which effectively enhances the interfacial bonding force between the layers, ensuring that the layers will not easily separate or delaminate when the material is subjected to external forces, thus ensuring the integrity and stability of the material structure. Example

[0022] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 3 As shown below, see details:

[0023] In a preferred embodiment, a flame-retardant reinforcing layer 5 is provided on one side of the middle reinforcing layer 4. The flame-retardant reinforcing layer 5 includes a first reinforcing layer 51, which is made of a nano-montmorillonite-boron composite coating. Furthermore, by providing the first reinforcing layer 51 and making it of a nano-montmorillonite-boron composite coating, the heat transfer to the interior of the material is effectively delayed, providing good thermal insulation protection for the material, enabling the material to maintain good performance in high-temperature environments, and reducing the risk of material damage and combustion caused by heat transfer.

[0024] In a preferred embodiment, a second reinforcing layer 52 is provided on one side of the first reinforcing layer 51. The second reinforcing layer 52 is made of aramid fiber-phosphate composite coating. Furthermore, by providing the second reinforcing layer 52 and making it of aramid fiber-phosphate composite coating, it can enhance the char layer during combustion, prevent the char layer from collapsing under high temperature and flame, and maintain the integrity and stability of the char layer.

[0025] A third reinforcing layer 53 is disposed inside the second reinforcing layer 52. The third reinforcing layer 53 is made of a carbon nanotube-aluminum hydroxide composite coating. Furthermore, by providing the third reinforcing layer 53 and making it of a carbon nanotube-aluminum hydroxide composite coating, it decomposes and absorbs a large amount of heat when heated, which can effectively reduce the surface temperature of the material and slow down the combustion process of the material. At the same time, the water vapor generated by decomposition can dilute the concentration of combustible gases, thereby inhibiting combustion.

[0026] An inner flame-retardant layer 6 is provided on one side of the third reinforcing layer 53. The inner flame-retardant layer 6 is made of a nitrogen-phosphorus synergistic flame-retardant coating. Furthermore, by providing an inner flame-retardant layer 6 and making it of a nitrogen-phosphorus synergistic flame-retardant coating, the flame retardant in the inner flame-retardant layer 6 can catalyze the formation of an initial char layer in the ABS resin. This char layer can form a barrier on the material surface, blocking heat and oxygen from contacting the material matrix and slowing down the thermal decomposition and combustion rate of the material.

[0027] The inner flame-retardant layer 6 has a filling layer 7 inside, which is made of polyolefin material. Furthermore, by providing the filling layer 7 and making it of polyolefin material, the melt viscosity of the material can be reduced, making the material easier to flow during processing and facilitating subsequent material molding and processing, thereby enhancing the practicality of the device.

[0028] The working process of this utility model is as follows:

[0029] By providing an outer protective layer 2 on one side of the masterbatch body 1, ultraviolet rays in sunlight can be effectively blocked, reducing the damage of ultraviolet rays to the internal structure of the material and preventing aging, discoloration, and embrittlement caused by long-term exposure to sunlight, thus extending the service life of the material. Simultaneously, by providing an antibacterial coating 3 on one side of the outer protective layer 2, the growth and reproduction of bacteria on the material surface can be effectively inhibited, reducing odors, stains, and potential threats to human health caused by bacterial growth. Furthermore, a middle reinforcing layer 4 is provided on one side of the antibacterial coating 3, effectively enhancing the interfacial bonding force between the layers and ensuring the material withstands external forces. The layers do not easily separate or delaminate, ensuring the integrity and stability of the material structure. The first reinforcing layer 51 effectively slows heat transfer to the material's interior, maintaining good performance under high temperatures and reducing the risk of damage and combustion due to heat transfer. The second reinforcing layer 52 forms a high-temperature resistant protective barrier on the material surface, effectively resisting the erosion of high-temperature flames and protecting the internal structure from high-temperature damage. Furthermore, the third reinforcing layer 53 decomposes and absorbs a large amount of heat when heated, effectively reducing the surface temperature and slowing the combustion process. Simultaneously, the water vapor produced by decomposition dilutes the concentration of combustible gases, inhibiting combustion and preventing the transfer of oxygen and heat. Combined with the decomposition of aluminum hydroxide, this significantly improves the flame-retardant properties of the material. The inner flame-retardant layer 6 rapidly inhibits the spread of flames, providing timely fire protection and effectively reducing the combustion rate and severity of a fire. Finally, the internal filling layer 7 reduces the melt viscosity of the material, making it easier to flow during processing, improving extrusion fluidity, and facilitating molding. The overall design further enhances the practicality of the device.

[0030] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
