Abstract

The invention discloses a polypropylene transparent material for melting, depositing and forming and a preparation method thereof. The material is prepared from the following materials: 70-99 parts of polypropylene, 0.1-1 part of clarifier, 1-2 parts of compatilizer, 0.1-5 parts of plasticizer, and 0.01-0.5 parts of stabilizer. After the clarifier is added, the phenomenon of large-area crystallizing during the cold molding of polypropylene is inhibited, the light transmission of the polypropylene material is greatly improved, a polypropylene product obtained by melting, depositing and molding has better tenacity, enhanced mechanical properties, higher practicability and greatly reduced material cost, and the application of the polypropylene material in the melting, depositing and molding field is favorably widened. The preparation method of the polypropylene transparent material is easy to operate, has lower requirement on process conditions and production equipment, can realize large-scale promotion and production, and has broad market prospect and excellent 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...
