Description

Technical Field

[0001] The present invention belongs to the technical field of polymer 3D printing consumables, and in particular relates to an ABS composite material for 3D printing consumables and a preparation method thereof. Background Art

[0002] ABS (Acrylonitrile-Butadiene-Styrene) is a thermoplastic polymer widely used in the field of 3D printing. It is widely used in desktop 3D printers and industrial-grade 3D printers due to its good moldability, excellent mechanical properties and high toughness. ABS material has good impact resistance and chemical resistance, and can achieve high-quality printing effects through a variety of molding processes. In addition, due to its easy processing and good surface treatment properties, ABS is widely used in many fields such as automotive parts, household items and electronic housings. However, despite the excellent performance of ABS in 3D printing, there are still some limitations, especially in applications in extreme environments.

[0003] Although ABS material is favored in many applications, its performance shows obvious limitations under high temperature and high stress conditions. Specifically, the heat deformation temperature of ABS is usually between 80-100°C. When the operating temperature exceeds this range, ABS tends to soften, resulting in shape distortion or deformation of the printed object. In addition, under high stress environments, ABS materials may experience brittle fracture, reducing their toughness and impact resistance. These limitations make it difficult for ABS to meet the needs in some industrial applications with high performance requirements, and there is an urgent need to find modification methods to enhance the performance of the material.

[0004] Based on this, it is urgent to improve the existing ABS materials and preparation methods used for 3D printing consumables. Summary of the invention

[0005] One of the purposes of the present invention is to address the deficiencies of the prior art and to provide an ABS composite material for 3D printing consumables that has certain toughness, impact resistance and high temperature resistance after being modified by a coupling agent.

[0006] In order to achieve the above-mentioned invention objectives, this application implements the following technical solutions:

[0007] An ABS composite material for 3D printing consumables, comprising, by weight:

[0008] ABS material: 60-70 parts;

[0009] Toughening agent material: 5-20 parts;

[0010] Modified filler: 15-30 parts;

[0011] Coupling agent material: 1-20 parts;

[0012] Among them, the coupling agent material is one or more of silane coupling agent, polymer coupling agent, and titanate coupling agent; the modified filler is one or more of talcum powder, calcium carbonate, titanium dioxide powder, glass beads, quartz powder, mineral oil, and glass powder; and the toughening agent material is SBS material or SEBS material.

[0013] The above technical solution produces the following technical effects:

[0014] In order to overcome the performance limitations of existing ABS materials under high temperature and high stress environments, this application proposes to modify ABS using a polymer coupling agent. These coupling agents can significantly enhance the interaction between the components in the composite material, thereby strengthening the bonding strength of the interface. Specifically, the coupling agent can form a chemical or physical interaction between the ABS matrix and the filler, enhance the bonding effect of the interface, and improve the dispersion of the filler. In addition, by improving the compatibility of the material, the coupling agent helps to disperse stress, enhance the impact resistance of the material, and reduce the probability of brittle fracture. Furthermore, the addition of the coupling agent can also increase the heat deformation temperature and heat resistance of the composite material, ensuring that it still maintains good physical and mechanical stability under high temperature conditions.

[0015] As a further improvement to the ABS composite material for 3D printing consumables of the present application, the silane coupling agent is KH-560 material.

[0016] As a further improvement to the ABS composite material for 3D printing consumables of the present application, the following components are included in parts by weight:

[0018] Toughening agent material: 5-10 parts;

[0019] Modified filler: 15-30 parts;

[0020] KH-560 Materials: 1-4 parts.

[0021] As a further improvement to the ABS composite material for 3D printing consumables of the present application, the polymer coupling agent is a polyvinyl alcohol material or a polyacrylate material.

[0022] As a further improvement to the ABS composite material for 3D printing consumables of the present application, the following components are included in parts by weight:

[0024] Toughening agent material: 10-15 parts;

[0025] Modified filler: 15-30 parts;

[0026] Polyacrylate material: 1-5 parts.

[0027] As a further improvement to the ABS composite material for 3D printing consumables of the present application, the titanate coupling agent is tetrabutyl titanate material.

[0028] As a further improvement to the ABS composite material for 3D printing consumables of the present application, the following components are included in parts by weight:

[0029] ABS material: 60-70 parts;

[0030] Toughening agent material: 5-10 parts;

[0031] Modified filler: 15-20 parts;

[0033] The second object of the present invention is to provide a method for preparing an ABS composite material for 3D printing consumables with certain toughness, impact resistance and high temperature resistance in view of the shortcomings of the prior art.

[0034] In order to achieve the above technical objectives, this application implements the following technical solutions:

[0035] A method for preparing an ABS composite material for 3D printing consumables as described above comprises the following steps:

[0036] S101, adding the coupling agent material into a stirrer containing 20-30° C. deionized water, and stirring the coupling agent material evenly by the stirrer;

[0039] S401, the mixture prepared in step S301 is uniformly fed into an extruder, and the mixture is cut into particles at an extrusion port of the extruder.

[0040] The above technical solution produces the following technical effects:

[0041] In the preparation method of the present application, the coupling agent is dispersed in deionized water to ensure uniform combination with the modified filler, thereby improving the uniformity and stability of the composite material. The coupling agent is evenly coated on the surface of the modified filler to improve the interfacial compatibility with the ABS matrix and enhance the performance of the composite material. The high-speed mixer ensures that ABS, toughening agent and modified filler are evenly mixed to form a uniform composite material precursor. The extruder processes the mixture into granules, which is convenient for 3D printing consumables processing and ensures the dimensional accuracy and consistency of the material. As a result, the quality of the ABS composite material used for 3D printing consumables is further improved.

DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the present application. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0045] Although the present application is disclosed as above with preferred embodiments, it is not intended to limit the claims. Any technical personnel in this field may make several possible changes and modifications without departing from the concept of the present application. Therefore, the scope of protection of the present application shall be based on the scope defined by the claims of the present application.

[0046] The present invention is further described in detail below in conjunction with specific implementation methods, but the embodiments of the present invention are not limited thereto.

[0047] It is known that under high stress environment, ABS material may experience brittle fracture, which reduces its toughness and impact resistance. These limitations make it difficult for ABS to meet the needs in certain industrial applications with high performance requirements. In particular, the existing ABS materials used for 3D printing consumables have limitations under high temperature and high stress conditions, and have technical defects such as insufficient thermal stability. The motivation for solving the above technical problems is to maintain the motivation of this application, and propose a technical solution of using polymer coupling agents to modify ABS materials so that these coupling agents can effectively improve the interaction between different components in the composite material and enhance the interface bonding force.

[0048] Specifically, the ABS composite material used for 3D printing consumables in this application includes, by weight:

[0049] ABS material: 60-70 parts; in the specific implementation process, it can be preferably: 60 parts, 61 parts, 62 parts, 63 parts, 64 parts, 65 parts, 66 parts, 67 parts, 68 parts, 69 parts or 70 parts. By adjusting the amount of ABS material, the mechanical properties of the final product can be fine-tuned to meet the application requirements of different 3D printing consumables.

[0050] Toughener material: 5-20 parts; in the specific implementation process, it can be preferably: 5 parts, 6 parts, 7 parts, 8 parts, 9 parts, 10 parts, 11 parts, 12 parts, 13 parts, 14 parts, 15 parts, 16 parts, 17 parts, 18 parts, 19 parts or 20 parts. The type and amount of toughener have a significant effect on the toughness of ABS composite materials. Preferred tougheners include but are not limited to SBS materials or SEBS materials. Among them, SBC is styrene-butadiene-styrene block copolymer, and SEBS is styrene-ethylene-butylene-styrene block copolymer. By selecting a suitable toughener, the impact resistance and toughness of the composite material can be effectively improved.

[0051] Modified filler: 15-30 parts; in the specific implementation process, it can be preferably: 15 parts, 16 parts, 17 parts, 18 parts, 19 parts, 20 parts, 21 parts, 22 parts, 23 parts, 24 parts, 25 parts, 26 parts, 27 parts, 28 parts, 29 parts or 30 parts. The addition of modified fillers can improve the thermal stability and dimensional stability of ABS composite materials, and at the same time improve the strength and rigidity of the material. The modified filler of the present application is one or more of talcum powder, calcium carbonate, titanium dioxide powder, glass beads, quartz powder, mineral oil, and glass powder. By controlling the type and amount of modified fillers, the comprehensive performance of the composite material can be further optimized to meet the requirements for material performance in the 3D printing process.

[0052] Coupling agent material: 1-20 parts; in the specific implementation process, it can be preferably: 1 part, 2 parts, 3 parts, 4 parts, 5 parts, 6 parts, 7 parts, 8 parts, 9 parts, 10 parts, 11 parts, 12 parts, 13 parts, 14 parts, 15 parts, 16 parts, 17 parts, 18 parts, 19 parts or 20 parts. The coupling agent plays a key role in the ABS composite material. It can improve the interface compatibility between the filler and the ABS matrix, thereby improving the overall performance of the composite material. Among them, the coupling agent material is one or more of a silane coupling agent, a polymer coupling agent, and a titanate coupling agent.

[0053] Further, the silane coupling agent is preferably the KH-560 material produced by Shandong Hengyu New Materials Co., Ltd. The main component of the KH-560 material is triethoxysilane. It plays a key role in composite materials, especially in improving the compatibility and interfacial mechanical properties between polymers and inorganic fillers. In the present application, the amino part in the KH-560 material can react with the carboxyl or hydroxyl of ABS or other polymers to form a cross-linked network, which cross-links and enhances the tensile strength and toughness of the material. At the same time, the siloxy group of the KH-560 material can form a good combination with the surface of the inorganic filler (such as talcum powder, calcium carbonate, etc.), increases the contact area between the filler and the polymer, and improves the interfacial adhesion.

[0054] Furthermore, the ABS composite material containing the KH-560 material includes, in parts by mass:

[0055] ABS material: 60-70 parts;

[0056] Toughening agent material: 5-10 parts;

[0057] Modified filler: 15-30 parts;

[0058] KH-560 Materials: 1-4 parts.

[0059] Furthermore, the polymer coupling agent is a polyvinyl alcohol material (PVA) or a polyacrylate material (PAA). Among them, common suppliers of polyvinyl alcohol materials (PVA) include Toyo-Filter, BASF, etc. PVA has strong hydrophilicity and can interact with polar groups (such as hydroxyl groups) in the polymer matrix to improve compatibility. Common suppliers of polyacrylate materials (PAA) include: BASF, Dow Chemical, etc. Polyacrylate material (PAA) is a polymer with hydrophilicity and adhesion, which can effectively improve the compatibility between ABS and other materials (such as inorganic fillers) and improve the mechanical properties of the material.

[0060] Preferably, the ABS composite material for 3D printing consumables containing polyvinyl alcohol material comprises, in parts by mass:

[0061] ABS material: 60-70 parts;

[0062] Toughening agent material: 10-15 parts;

[0063] Modified filler: 15-30 parts;

[0064] Polyvinyl alcohol material: 1-5 parts.

[0066] ABS material: 60-70 parts;

[0067] Toughening agent material: 10-15 parts;

[0068] Modified filler: 15-30 parts;

[0069] Polyacrylate material: 1-5 parts.

[0070] Furthermore, using a titanate coupling agent as a modifier for ABS materials is an effective modification scheme. Titanate coupling agents are commonly used to improve the compatibility between polymers and fillers, and enhance impact resistance, heat resistance and mechanical properties. The preferred titanate coupling agent of the present application, such as tetrabutyl titanate (TBT), has good chemical stability and excellent interfacial bonding ability. TBT can significantly improve the mechanical properties and toughness of the material by forming chemical bonds with polar groups such as hydroxyl and carboxyl groups in ABS materials.

[0071] Preferably, the ABS composite material for 3D printing consumables containing tetrabutyl titanate comprises, in parts by mass:

[0072] ABS material: 60-70 parts;

[0073] Toughening agent material: 5-10 parts;

[0074] Modified filler: 15-20 parts;

[0075] Tetrabutyl titanate material: 1-3 parts.

[0076] In order to further improve the ABS composite material used for 3D printing consumables in this application, this application makes improvements to the existing preparation method. Specifically, this application prepares the ABS composite material used for 3D printing consumables through the following technical solutions:

[0077] S101, adding the coupling agent material into a stirrer containing 20-30° C. deionized water, and stirring the coupling agent material evenly by the stirrer;

[0078] S201, adding the modified filler into a stirrer, and stirring the stirrer so that the coupling agent material is coated on the modified filler;

[0079] S301, adding the modified filler coated with the coupling agent material, the ABS material and the toughening agent material into a high-speed mixer and mixing for 10-20 minutes;

[0080] S401, the mixture prepared in step S301 is uniformly fed into an extruder, and the mixture is cut into particles at an extrusion port of the extruder.

[0081] Wherein, in step S101, the stirring rate of the stirrer is 500rpm-1500rpm; in step S201, the stirring rate of the stirrer is 800rpm-1000rpm; the extruder in step S401 is a twin-screw extruder or a single-screw extruder, and the extrusion temperature of the extruder is 180-220°C.
