Background
The 3D printing technology is a special manufacturing technology that arose in the late 20 th century and the 80 s, and mainly includes Fused Deposition Modeling (FDM), photocuring modeling (SLA), selective laser sintering modeling (SLS), Layered Object Manufacturing (LOM), and other types of technologies. The FDM technology is the most widely applied 3D printing technology at present due to the advantages of no need of a mold, more optional materials, flexible manufacturing method, low cost and the like. In the aspect of FDM3D printing materials, thermoplastic materials such as polylactic acid (PLA), Acrylonitrile Butadiene Styrene (ABS), Polycarbonate (PC) and the like are more commonly used, wherein the ABS material is the most widely used FDM3D printing thermoplastic material due to its good moldability and mechanical properties and low price.
However, the ABS processing temperature is generally above 200 ℃, so that the ABS printing ink is not suitable for occasions requiring low-temperature printing, such as a 3D printing pen for children, and if the printing temperature is too high, the pen point is easy to scald the children. In addition, ABS is used as a consumable of a 3D printing pen for children, and good toughness and glossiness are generally required to ensure high safety in the using process and bright color of products.
Therefore, there is a need to develop an ABS material that can be printed at low temperature and has high toughness and high gloss.

Preferably, the weight content of MMA (methyl methacrylate) in the SMMA resin is 50-75%. When the weight content of MMA in the SMMA resin is less than 50%, the resulting alloy material has low gloss, and therefore the weight content of MMA in the SMMA resin is preferably 50 to 75% to obtain high gloss. The weight content of MMA in SMMA resin can be determined by hydrogen nuclear magnetic resonance method.

Examples and comparative examples
Each of the examples and comparative examples provides an ABS alloy material having a composition shown in tables 1-2 (in the tables, "-" indicates a content of 0), and the preparation method thereof comprises the steps of: drying ABS resin, EVA resin and SMMA resin, uniformly mixing with antioxidant and lubricant in a mixing device, performing melt blending extrusion in a mechanical device, performing water cooling, granulating, and drying to obtain the corresponding ABS alloy material, wherein the melting temperature is 185 ℃, and the screw rotation speed is 200-. The ABS materials of the examples and the comparative examples have the same preparation process steps and other process parameters except for different formulas.
The ABS alloy materials of the examples and the comparative examples are subjected to performance tests, and the specific method is as follows:
notched izod impact strength: GB/T1843-2008, type A notch;
the melt flow rate is GB/T3682-;
gloss: sheets of 1 x 100mm were extruded with a haake and then tested for 60 ° gloss with a gloss meter.
TABLE 1 compositions and Properties of ABS alloy materials of examples 1-10
TABLE 2 ABS alloy compositions and Properties of examples 11-16 and comparative examples 1-3
As can be seen from tables 1 and 2, the ABS alloy material of the invention has high melt flow rate, toughness and glossiness, the melt flow rate is more than 2g/10min (170 ℃/10kg), and the cantilever beam notch impact strength (A-type notch) is 5kJ/m2Above, the glossiness is above 70. Pure ABS resin, as in comparative example 1, did not melt at low temperatures of 170 ℃. If the amount of the SMMA resin is too small, as in comparative example 2, the glossiness of the ABS alloy material is obviously lower; the use of an excessive amount of SMMA resin, as in comparative example 3, results in a lower impact strength of the ABS alloy material.
Comparing example 4 with examples 2 and 5 to 6, it is found that the lower melt flow rate of the ABS resin results in lower melt flow rate of the ABS alloy material, and in order to ensure smoother 3D printing process for children, the melt flow rate of the ABS resin is preferably 30 to 70g/10min (220 ℃/10 kg). Comparing examples 2, 8, 9 and 11-13, it can be seen that the melt flow rate of the EVA resin is low, which results in low melt flow rate and low gloss of the ABS alloy material; the EVA resin has a high melt flow rate, which results in low notched izod impact strength of the ABS alloy material. Comparing examples 2, 7-10 and 12, it can be seen that the lower weight content of VA in the EVA resin can result in lower notched izod impact strength of the ABS alloy material; the EVA resin has a higher VA content by weight, which results in a lower glossiness of the ABS alloy material. Comparing examples 2 and 14-16, it is found that the lower MMA content in the SMMA resin results in lower gloss of the ABS alloy material.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the protection scope of the present invention, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
