Preparation method of grain composition silicon carbide slurry for photocuring additive manufacturing
The invention relates to a preparation method of grain-graded silicon carbide slurry for photocuring additive manufacturing. According to the preparation method of the grain composition silicon carbide slurry for photocuring additive manufacturing, coarse silicon carbide particles and fine silicon carbide particles are evenly mixed with resin, a dispersing agent and an initiator in a grain composition mode, and the silicon carbide slurry is obtained. Meanwhile, the silicon carbide slurry prepared by selecting proper types and adding proportions of the resin, the dispersing agent and the initiator according to the mass ratio has relatively good dispersity, relatively low viscosity and a relatively good curing effect, and the problems that printing is not easy due to relatively high viscosity and too fast sedimentation of the slurry and molding is not easy due to relatively low curing depth in the 3D printing process are solved. And the dispersing agent not only reasonably reduces the viscosity of the slurry, but also enables the silicon carbide slurry to be dispersed more uniformly, and the grading of particles can change the rheological behavior of the slurry, so that the slurry with high solid content can be prepared.
一种光固化增材制造的颗粒级配碳化硅浆料的制备方法。所述光固化增材制造的颗粒级配碳化硅浆料的制备方法将粗碳化硅颗粒和细碳化硅颗粒通过颗粒级配的方式与树脂、分散剂、引发剂混合均匀,得到碳化硅浆料。同时按质量比选择合适的树脂、分散剂以及引发剂的种类与添加比例制备出的碳化硅浆料,具有分散性较好、粘度较低且固化效果较好,在3D打印过程中不会出现因浆料的粘度较大,沉降过快而不易打印和固化深度较低而不易成型的问题。而且因为分散剂不仅合理的降低的浆料的粘度,也使碳化硅浆料分散的更加均匀,颗粒的级配可以改变浆料的流变行为,从而可以制备出高固相含量的浆料。
