Problems solved by technology

At present, it can be applied to catering utensils, daily necessities, agricultural materials, biomedical polymer materials, food and drug packaging materials, etc., but PBS materials directly used for 3D printing have not been reported yet.
[0006] The direct application of pure PBS to 3D printing has the problem of heat shrinkage, and the main chain of PBS is composed of aliphatic carbon-oxygen chains, so the toughness and tensile strength need to be further improved

Abstract

The invention discloses a PBS (Poly Butylene Succinate) / carbon material composite wire for 3D (Three-dimensional) printing and a preparation method thereof. The technical scheme is as follows: 1, a formula comprises 70 to 80 percent by weight of PBS, 2 to 50 percent by weight of a carbon material, 0.1 to 0.5 percent by weight of a chain expander, 0.1 to 0.5 percent by weight of a cross-linking agent, 0.1 to 2 percent by weight of a nucleating agent, 0.1 to 0.5 percent by weight of a heat stabilizer, 0.2 to 1 percent by weight of an antioxidant and 0.2 to 1 percent by weight of a lubricant; 2, the preparation method comprises the steps of (1) drying, (2) weighing, (3) high-speed kneading, (4) melt extrusion, (5) cooling drawing, and (6) rolling bundling. A high molecular material applicable to the 3D printing is prepared from completely-degraded biological materials namely the PBS and the carbon material. Compared with a conventional PLA (Poly Lactic Acid) wire, the high molecular material has lower printing temperature, higher tensile strength and flexibility, is applicable to multiple 3D forming technologies, and has a broad application prospect in the field of the 3D printing.

Description

technical field [0001] The invention belongs to a PBS / carbon material composite wire used for 3D printing and a preparation method thereof. Background technique [0002] 3D printing technology, that is, additive manufacturing technology, together with robotics and artificial intelligence technology, is known as the key technology to promote the third industrial revolution. 3D printing technology is a rapid additive manufacturing technology that generates three-dimensional entities by adding materials layer by layer. Compared with traditional subtractive manufacturing technology, it has the characteristics of low loss, intelligent, precise and efficient product manufacturing. Especially in the field of high-end manufacturing involving complex shapes, 3D printing technology has shown great advantages. [0003] According to the principle of printing technology and the different materials used, 3D printing technology can be divided into laser cladding forming technology (LCF), ...
