Abstract

The invention discloses an ABS / PC 3D consumable material special material and a preparation method thereof. The material comprises the components by the mass percentage: 45% to 65% of ABS, 35% to 45% of PC, 4% to 10% of a toughening agent, 1% to 5% of a compatibilizer, 0.1% to 0.3% of an antioxidant, and 0.1% to 1% of a lubricant. While improving the impact resistance of consumable materials, the prepared ABS / PC 3D consumable material special material reduces the molding shrinkage rate of products, overcomes the shortcomings that ABS consumable materials generate bottom surface warping and large products are easy to fault during a printing process, improves the surface finish degree and the success rate of the printed products, and is new material applied to the technical field of 3D printing.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a special material for ABS / PC 3D consumables and a preparation method thereof. Background technique [0002] In recent years, my country's 3D printing technology has developed rapidly, and the 3D printing market has become increasingly mature, especially in the field of FDM3D printing technology, which has simple equipment, fast molding speed, and low printing cost, and has achieved good development in China. With the increasing maturity of FDM technology, the market of 3D printing consumables is developing slowly, which limits the popularization and application of 3D printing technology. ABS material is currently the mainstream FDM3D printing consumable in China. ABS is a kind of resin with good comprehensive properties. It has high impact strength and surface hardness in a relatively wide temperature range. The heat distortion temperature is higher than tha...
