Embodiment 1

[0064] Example 1: 50 parts of polyvinyl alcohol (polymerization degree 2000, alcoholysis degree 72.0 (mol)%), 6 parts of triethanol diisooctanoate, 5 parts of soft water, 0.1 part of saturated aliphatic dicarboxylate G32 in Mix uniformly under stirring, heat while stirring at 90°C, and stop heating after 10 minutes. Then put the material into the silo with stirring, use the screw to automatically transport the material to the screw extruder, keep the screw temperature at 120°C, melt and extrude under normal pressure, then cool the material to 20°C, and cut The pelletizer is used to cut pellets to prepare a water-soluble thermoplastic polyvinyl alcohol resin at room temperature. The prepared polyvinyl alcohol resin is dried at 40°C for 10 hours, and at a temperature of 120-160°C, single-screw extrusion is used to produce water-soluble 3D printing consumables at room temperature.

[0065] The obtained 3D printing consumable has a decomposition temperature of 260°C, a melting temper...

Embodiment 2

[0066] Example 2: Mix 85 parts of polyvinyl alcohol (degree of polymerization 2400, degree of alcoholysis 88.0 (mol)%), 20 parts of glycerol, 20 parts of soft water, and 10 parts of silica, and mix them evenly under stirring. Stir while heating at 40°C, and stop heating after 10 hours. Then put the material into the silo with stirring, use the screw to automatically convey the material to the single screw extruder, keep the screw temperature at 130℃, melt and extrude under the pressure of 0.01MPa (gauge pressure), and then cool the material At 30°C, the room temperature water-soluble thermoplastic polyvinyl alcohol resin is prepared by pelletizing with a pelletizer. The prepared polyvinyl alcohol resin is dried at 80°C for 1h, and at a temperature of 140~150°C, it is made by single screw extrusion. Water-soluble 3D printing consumables at room temperature.

Embodiment 3

[0068] Example 3: Mix 50 parts of conventional polyvinyl alcohol (polymerization degree 1000, alcoholysis degree 90.0 (mol)%), 32 parts polyethylene glycol, 17 parts soft water, 1 part silicon dioxide, and mix well under stirring , Heat while stirring at 50℃, stop heating after 7h. Then put the material into the silo with stirring, use a single screw to automatically transport the material to the single screw extruder, keep the screw temperature at 130°C, melt and extrude under normal pressure, and then cool the material to 35°C. The room temperature water-soluble thermoplastic polyvinyl alcohol resin is prepared by pelletizing by a pelletizer. The prepared polyvinyl alcohol resin is sealed and stored, and dried at 80℃ for 5h before use. At 150℃, it is extruded by a single screw to make it at room temperature. Water-soluble 3D printing consumables.

Abstract

The invention relates to a room-temperature water-soluble 3D printing consumptive material. The room-temperature water-soluble 3D printing consumptive material is prepared by drying water-soluble polyvinyl alcohol resin under the condition of 40-120 DEG C, wherein the water-soluble polyvinyl alcohol resin is prepared from polyvinyl alcohol, a plastifier, soft water and a processing aid in effective quantity; the polymerization degree of the polyvinyl alcohol is 1000-2400, and the alcoholysis degree of the polyvinyl alcohol is 72mol%-92.0mol%; the plastifier is one or the combination of several kinds of glycerin, polyethylene glycol and triethylene glycol di-2-ethylhexoate(triglycol dioctate); the processing aid is one or the combination of several kinds of talcum powder, silicon dioxide and saturated aliphatic dicarboxylic ester; and the drying time is 1-24h. After the manufactured 3D printing consumptive material is used for 3D printing, the 3D printing consumptive material can dissolve in water of 20-40 DEG C, so that three-dimensional products with hollowed-out patterns can be manufactured.

Description

Technical field [0001] The invention relates to a 3D printing consumable, in particular to a normal temperature water-soluble 3D printing consumable and a preparation method thereof. Background technique [0002] 3D printing technology, also known as three-dimensional printing technology, refers to the production of 3D entities by adding materials layer by layer through a 3D printer that can "print" real objects. The most prominent advantage of 3D printing technology is that it can directly generate objects of any shape from computer graphics data without machining or molds, thereby greatly shortening the product development cycle, improving productivity and reducing production costs. [0003] The core that restricts the development of 3D printing technology is not printing, but materials. Only when new material technology develops, 3D printing technology can further realize more functions. The current consumables in general mainly include: powder consumables, used for laser sinte...
