Abstract

The invention discloses a PBC (Poly Butylene glycol Carbonate) material for 3D (Three-dimensional) printing and a preparation method thereof. The technical scheme is as follows: 1, a formula comprises 75 to 95 percent by weight of PBS (Poly Butylene Succinate), 0.1 to 20 percent by weight of inorganic filler, 0.1 to 0.5 percent by weight of a chain extender, 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 an inorganic filler-modified completely-degraded biological material PBC, and has higher tensile strength and flexibility, and the class of 3D printing materials is expanded.

Description

technical field [0001] The invention relates to a polybutylene carbonate (PBC) material, in particular to a PBC material 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 clad...
