Problems solved by technology

However, the printing temperature needs to be 230~270°C, which requires a higher configuration of the 3D printer
[0005] 3D printing technology cannot be promoted and applied on a large scale at present, mainly limited to 3D printing materials
This requires maintaining a high printing temperature, usually greater than 200 ° C, which puts forward higher configuration requirements for the 3D printer, and the service life of the 3D printer is therefore limited

Abstract

The invention discloses an ABS (acrylonitrile-butadiene-styrene) composite material applicable to 3D printing and a preparation method thereof. The preparation method comprises the following steps: adding 3-aminopropyltrimethoxy silane into acetone, standing at room temperature, sequentially adding hydroquinone, tritolyl phosphate and methyl 2-cyanoacrylate, stirring at room temperature, adding ABS particles, and continuing stirring at room temperature to obtain the ABS composite material applicable to 3D printing. The content of the ABS is 40-60%, the content of the methyl 2-cyanoacrylate is 5-30%, the content of the tritolyl phosphate is 1-5%, the content of the acetone is 20-30%, the content of the 3-aminopropyltrimethoxy silane is 0.2-0.5%, and the content of the hydroquinone is 0.1-0.5%. The composite material disclosed by the invention can be used for 3D printing within the temperature range of 30-50 DEG C, and overcomes the defect that the conventional 3D printing needs to melt the high-molecular polymers under high-temperature conditions; and the preparation method has the advantages of simple technique and low production cost.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and relates to an ABS composite material that can be used for 3D printing and a preparation method thereof. Background technique [0002] 3D (three-dimensional) molding technology is a product manufacturing method that uses plastic materials for layer-by-layer or point-by-point integral accumulation. A hundred years ago, the rudiment of its idea appeared, including the example of using layered methods to make three-dimensional map models. The basic principle is to collect the three-dimensional structure information of related objects according to the "layered accumulation" method, model the data, and perform layered decomposition to form respective data files by layer, that is, a series of two-dimensional layer data; and then The processing path is reversely established according to different forming processes; finally, a three-dimensional product entity is manufactured layer by lay...
