Preparation of three-dimensional printing and rapid prototyping boron nitride powder material
The invention discloses a preparation method of a three-dimensional printing and rapid prototyping boron nitride powder material. The method is characterized by comprising the following steps: firstly, carrying out pre-treatment on boron nitride powder employing fatty acid methyl ester polyoxyethylene ether to obtain pretreated boron nitride powder; adding 5%-15% by mass of N,N-dimethylformamide and 2%-8% by mass of nylon resin to a reactor, stirring, dissolving and adding 80%-90% of pretreated boron nitride powder, wherein the sum of the components by mass percent is 100%; stirring evenly, transferring into a grinding miller, starting the grinding miller at the rotating speed of 200r/min, and grinding at a room temperature for 3-4 hours, so as to obtain the three-dimensional printing and rapid prototyping boron nitride powder material. According to the material disclosed by the invention, a binder does not need to be sprayed; the forming accuracy is high; the material has the advantages of simple preparation technology and low production cost; the conditions are easy to control; and industrialized production is easy to realize.
