Polyvinyl alcohol wire for fused deposition molding and processing method of polyvinyl alcohol wire

Abstract

The invention relates to a preparation method of high polymer materials, and particularly relates to a polyvinyl alcohol wire for fused deposition molding and a processing method of the polyvinyl alcohol wire. The polyvinyl alcohol wire comprises the following raw materials in parts by weight: 100 parts of polyvinyl alcohol resin, 20-40 parts of a plasticizer, 0.5-2 parts of an antioxidant, 5-10 parts of a heat stabilizer, 0.2-1 part of a lubricating agent and 0.1-0.5 part of an anti-blocking agent, wherein the anti-blocking agent is one of oleamide and erucyl amide. The polyvinyl alcohol wire disclosed by the invention has the advantages of high heat stability, good melt processing property, excellent mechanical property, stable wire diameter, good water solubility, simple production process, high efficiency and low cost.

Description

technical field [0001] The invention relates to a manufacturing method of a polymer material, in particular to a polyvinyl alcohol filament material used for fusion deposition molding and a processing method thereof. Background technique [0002] 3D printing technology was born in the late 1980s. It is a high-tech manufacturing technology that integrates modern scientific and technological achievements such as CAD technology, numerical control technology, laser technology and material technology. Fused Deposition Modeling (Fused Deposition Modeling, FDM) technology is a kind of 3D printing technology. Its principle is to layer the molded parts first, and then superimpose them layer by layer from bottom to top. During the layer-by-layer stacking molding process, the cantilever and hollow parts need to be supported, otherwise they will collapse and cannot be formed. The materials used in the FDM process are basically thermoplastics, which are supplied by wire, and the parts c...
