Description

Technical Field

[0001] The present application relates to the technical field of polymer materials, and in particular to a polyamide / acrylonitrile-butadiene-styrene copolymer alloy material and a preparation method and application thereof. Background Art

[0002] As one of the five major engineering plastics, polyamide (also known as nylon, PA) has unique properties such as low specific gravity, high strength, good rigidity, impact resistance, wear resistance, oil and chemical resistance, and good self-lubrication. In addition, its raw materials are easily available, processing is simple, and cost is low. It has been widely used in the automotive industry, electronics, home appliances, transportation and other fields. At present, PA still has problems such as low dry and low temperature notched impact strength, high water absorption, and poor dimensional stability. It needs to be improved through modification to expand its application field.

[0003] Acrylonitrile-butadiene-styrene copolymer (ABS) has excellent properties of rigidity, hardness and toughness, and is easy to process. It is a widely used thermoplastic polymer material. In order to improve the notched impact performance and water absorption of PA, there is a method to provide a high-toughness PA / ABS alloy material. This material combines the advantages of PA and ABS materials. While maintaining the strength of PA, it significantly improves the toughness of the material, making it perform well in fields with high strength and high toughness requirements.

[0004] However, the heat resistance of PA / ABS alloy materials needs to be further improved. Summary of the invention

[0005] The present application provides a polyamide / acrylonitrile-butadiene-styrene copolymer (PA / ABS) alloy material and a preparation method and application thereof. The PA / ABS alloy material has good toughness and strength as well as high heat resistance.

[0006] In a first aspect of the present application, a polyamide / acrylonitrile-butadiene-styrene copolymer alloy material is provided, comprising the following raw material components in parts by weight:

[0007] 5 to 90 parts of polyamide, 5 to 90 parts of a first acrylonitrile-butadiene-styrene copolymer, 5 to 90 parts of a second acrylonitrile-butadiene-styrene copolymer, and 1 to 20 parts of a compatibilizer;

[0008] The mass percentage of butadiene in the first acrylonitrile-butadiene-styrene copolymer is 50% to 70%;

[0009] The mass percentage of styrene in the second acrylonitrile-butadiene-styrene copolymer is 50% to 70%;

[0010] The compatibilizer includes a copolymer of a core-shell elastomer grafted with maleic anhydride.

[0011] The above polyamide / acrylonitrile-butadiene-styrene copolymer alloy material modifies polyamide (PA) by using two acrylonitrile-butadiene-styrene copolymers (ABS). The first ABS can improve the toughness of the material, and cooperate with the second ABS to comprehensively optimize the strength and heat resistance of the material. At the same time, using a copolymer of a core-shell elastomer grafted with maleic anhydride as a compatibilizer can improve the interfacial compatibility between ABS and PA. Moreover, its particle size, composition, morphology, etc. are less affected by processing conditions, with a wide adaptation range. It also has good dispersibility in the PA / ABS system, and is easy to cause the cavitation effect of the material, significantly improving the toughening effect. On this basis, reasonably adjusting the weight parts of each raw material component can make the prepared PA / ABS alloy material have good toughness and strength, while also having high heat resistance.

[0012] In addition, in the traditional method, the improvement of the toughness of the alloy material is often accompanied by a decrease in fluidity. The present application also finds through research that this PA / ABS alloy material also has good fluidity.

[0013] In one embodiment, the polyamide is one or both of PA6 and PA66. Using a suitable type of polyamide can further improve the strength performance of the material.

[0014] In one embodiment, the relative viscosity of the polyamide is 2.4 to 2.9. Using a suitable polyamide viscosity can further improve the fluidity of the material. Further, the relative viscosity of the polyamide is 2.6 to 2.8.

[0015] In one embodiment, based on weight parts, the polyamide / acrylonitrile-butadiene-styrene copolymer alloy material includes the following raw material components:

[0016] 35 to 60 parts of polyamide, 10 to 40 parts of the first acrylonitrile-butadiene-styrene copolymer, 10 to 40 parts of the second acrylonitrile-butadiene-styrene copolymer, and 5 to 10 parts of the compatibilizer.

[0017] In one embodiment, the core-shell elastomer has an acrylonitrile-butadiene-styrene copolymer as the shell and an ethylene-propylene copolymer as the core. The compatibilizer uses an ethylene-propylene copolymer as the soft core. Compared with the traditional acrylonitrile-butadiene-styrene grafted maleic anhydride copolymer compatibilizer, the ethylene-propylene copolymer has a lower glass transition temperature than butadiene, which can, to a certain extent, better improve the problem of low dry-state impact strength of polyamide, and at the same time can also improve the fluidity of the alloy material. Further, in the core-shell elastomer, the mass percentage of the core is 10% to 30%.

[0018] In one embodiment, the raw material components further include 0.2 parts to 2 parts of a functional additive, and the functional additive includes one or both of an antioxidant and a lubricant. By introducing a certain amount of the functional additive, the durability and processability of the alloy material can be improved, etc.

[0019] In one embodiment, the antioxidant includes one or more of hindered phenol antioxidants, phosphite antioxidants, and thioether antioxidants. By using a suitable type of antioxidant, it has good compatibility with the other raw material components and can enhance the durability of the alloy material.

[0020] In one embodiment, the lubricant includes one or more of hydrocarbon lubricants, stearic acid soap lubricants, stearic acid ester lubricants, and stearic acid amide lubricants. By using a suitable type of lubricant, it has good compatibility with the other raw material components and can enhance the processability of the alloy material.

[0021] In a second aspect of the present application, there is provided a method for preparing the polyamide / acrylonitrile-butadiene-styrene copolymer alloy material described in the first aspect, including the following steps:

[0022] Mix the raw material components, and melt, extrude, and pelletize the obtained mixture.

[0023] The above preparation method has simple steps and is convenient for industrial implementation.

[0024] In one embodiment, melting and extrusion are carried out by means of twin-screw extrusion;

[0025] Optionally, the extrusion temperature is 210°C to 240°C;

[0026] Optionally, the screw speed is 200 to 400 r / min.

[0027] By reasonably adjusting the processing parameters, the raw material components can be fully and evenly mixed, which is beneficial to the exertion of the material's advantages.

[0028] In a third aspect of the present application, there is provided the application of the polyamide / acrylonitrile-butadiene-styrene copolymer alloy material described in the first aspect in electronic and electrical appliances or household appliances. Specific Embodiments

[0039] In this application, the room temperature generally refers to 4°C to 30°C, preferably 20 ± 5°C.

[0040] Currently, there is a method of introducing maleimide-styrene-maleic anhydride copolymer as a heat-resistant agent into the PA / ABS alloy system in order to improve its heat resistance. Although this kind of method can improve the heat resistance of the alloy material to a certain extent, it will cause different degrees of decline in toughness and strength, that is, it is difficult to have high heat resistance while having good toughness and strength.

[0041] Based on this, through research, it is found in this application that by using appropriate first ABS and second ABS for compounding to modify PA, without the need to additionally introduce a heat-resistant agent, the heat resistance of the alloy material can be effectively improved, and at the same time, relatively high toughness and strength can be taken into account.

[0042] Some examples of this application provide a polyamide / acrylonitrile-butadiene-styrene copolymer alloy material, which includes the following raw material components by weight:

[0043] 5 to 90 parts of polyamide, 5 to 90 parts of first acrylonitrile-butadiene-styrene copolymer, 5 to 90 parts of second acrylonitrile-butadiene-styrene copolymer, and 1 to 20 parts of compatibilizer;

[0044] The mass percentage of butadiene in the first acrylonitrile-butadiene-styrene copolymer is 50% to 70%;

[0045] The mass percentage of styrene in the second acrylonitrile-butadiene-styrene copolymer is 50% to 70%;

[0046] The compatibilizer includes a copolymer of core-shell elastomer grafted with maleic anhydride.

[0047] For the above polyamide / acrylonitrile-butadiene-styrene copolymer alloy material, by using two acrylonitrile-butadiene-styrene copolymers (ABS) to modify polyamide (PA), the first ABS can improve the toughness of the material, and cooperate with the second ABS to comprehensively optimize the strength and heat resistance of the material. At the same time, using a copolymer of core-shell elastomer grafted with maleic anhydride as a compatibilizer can improve the interfacial compatibility between ABS and PA, and its particle size, composition, morphology, etc. are less affected by processing conditions, with a wide adaptation range, and it also has good dispersibility in the PA / ABS system. At the same time, it is easy to cause the cavitation effect of the material, significantly improving the toughening effect. On this basis, reasonably adjusting the weight parts of each raw material component can enable the prepared PA / ABS alloy material to have good toughness and strength while also having relatively high heat resistance.

[0048] In addition, in traditional methods, the improvement of the toughness of alloy materials is often accompanied by a decrease in fluidity.
