Example Embodiment

[0022] Example 1

[0023] In this embodiment, a transparent polystyrene linear material for 3D printing is prepared as follows:

[0024] Use a balance to accurately weigh Total polystyrene GPPS-124010Kg, Maomingzhong and K glue (transparent styrene-butadiene random copolymer, in which the molar percentage of butadiene is about 30%) SL- 803G2.5Kg, dried at 80℃ and then pre-dispersed and compounded, and then melted and compounded in a twin-screw compound extrusion equipment at 230℃ for 6 minutes, and then extruded in a circular die with a diameter of 1.75mm. The wire rod is cooled and shaped by a cooling water tank, pulled by a two-wheel tractor, wound at a high speed on a duplex winding machine at a speed of 30m / min, and finally dried and ready to be obtained.

Example Embodiment

[0025] Example 2

[0026] In this embodiment, a transparent polystyrene linear material for 3D printing is prepared as follows:

[0027] Accurately weighing Yangzi Petrochemical-BASF's PS with balance scale 165H10Kg, Maomingzhong and K glue SL-805F3.0Kg, dried at 100℃ and then pre-dispersed and compounded, and then melt compounded in twin-screw compound extrusion equipment at 220℃ for 8 minutes, and then in the diameter of 3.0mm Extruded in a circular die, the extruded wire is cooled and shaped by a cooling water tank, pulled by a two-wheel tractor, rewinded at a high speed on a duplex winder at a speed of 40m / min, and finally dried and ready to be obtained.

Example Embodiment

[0028] Example 3

[0029] In this embodiment, a transparent polystyrene linear material for 3D printing is prepared as follows:

[0030] Accurately weighing Yangzi Petrochemical-BASF's PS with balance scale 143E5Kg, GPPS-535N5Kg, Maomingzhong and K glue SL-801G 2.5Kg, dried at 80℃ and then pre-dispersed compounding, and then melt compounding at 210℃ for 10 minutes in the twin-screw compound extrusion equipment. It is extruded in a 1.75mm circular die. The extruded wire is cooled and shaped by a cooling water tank, pulled by a two-wheel tractor, and wound at a high speed on a duplex winder at a speed of 30m / min. Finally, it is dried and ready.

Abstract

The invention relates to a transparent polystyrene linear material for 3D printing and a preparation method thereof. The transparent polystyrene linear material is prepared by adopting the following raw materials: a compound of transparent polystyrene and transparent styrene-butadiene irregular copolymer in a mass ratio of (0 to 90): (100 to 10); transparent pigments accounting for 0 to 5 percent of weight of the compound; and an antioxidant accounting for 0 to 5 percent of weight of the compound. The polystyrene linear material for the 3D printing is simple in preparation process, low in cost, good in mobility, high in strength, high in flexibility, capable of being randomly bent and high in transparency and overcomes the weaknesses that the high-flexibility polystyrene linear material for the 3D printing on the market at present such as ABS, HIPS and the like is relatively low in mobility, has high possibility of blocking a printer nozzle and is not transparent.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a polystyrene linear material for 3D printing and a preparation method thereof. Background technique [0002] 3D printing technology originated in the United States at the end of the 19th century, even before the Internet. 3D printing began to develop as early as the 1980s, but it was not until recent years due to the continuous advancement of information technology, the continuous updating of mechanical automation and the promotion of the Internet that the "software core" of 3D printing - "digital model" and "hardware" "Basic" has been developed at a high speed, the cost of 3D printers has continued to drop, and the golden age of 3D printing technology applications has officially arrived. 3D printing technology is called the "third industrial revolution" and belongs to the field of additive intelligent manufacturing. The manufacturing process is to first design and process t...
