Abstract

The invention discloses a polypropylene transparent material for fused deposition molding and a preparation method thereof. The polypropylene transparent material is prepared from 70-99 parts of polypropylene, 0.1-1 part of a transparent agent, 1-2 parts of a compatibilizing agent, 0.9-3 parts of a lubricating agent, 0.1-5 parts of plasticizer and 0.01-0.5 part of stabilizer. After the transparent agent is added, the phenomenon of large-area crystallization in cooling molding of polypropylene is restrained, and the light transmission of the polypropylene material is greatly improved; a polypropylene product obtained through fused deposition molding has better toughness and higher practicality, the mechanical property of the polypropylene product is improved, the material cost is greatly lowered, and application of the polypropylene material in the fused deposition molding field is easily widened. The preparation method of the polypropylene transparent material is easy to implement, requirements for process conditions and production equipment are low, large-scale production and popularization can be achieved, and the preparation method has broad market prospects and brings great market benefits.

Description

technical field [0001] The invention belongs to the fields of 3D printing technology and plastic processing, and in particular relates to a polypropylene transparent material for fused deposition molding and a preparation method thereof. Background technique [0002] 3D printing technology, also known as additive manufacturing technology, is a technology that uses bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing based on digital model files. 3D printing technology has been applied in many fields such as information technology, material science, and precision machinery, and it is becoming more and more competitive in today's manufacturing industry, so it is called "manufacturing technology with industrial revolution significance". 3D printing technology breaks through the traditional material deformation molding and removal molding process, and can quickly manufacture three-dimensional solid parts of any complex shape withou...
