Ceramic 3D printing paste with high curing capacity and preparation method thereof
The invention discloses a ceramic 3D printing paste material with high curing capacity, wherein the ceramic 3D printing paste material is composed of the following ingredients in parts by weight: 25 to 45 parts of photosensitive resin, 30 to 60 parts of SiC powder, 0.5 to 2.8 parts of dispersing agents, 0.1 to 0.5 part of photoinitiators, 0.2 to 1 part of anti-settling agents and 25 to 35 parts of absolute ethyl alcohol. The photosensitive resin is a mixed solution of a monofunctional resin monomer and a bifunctional resin monomer, and the mass ratio of the monofunctional resin monomer to the bifunctional resin monomer is (0.5-1):(2-4). The invention further provides a preparation method of the ceramic 3D printing paste. According to the ceramic 3D printing paste with the high curing capacity, the mode that powder wraps resin to be pre-activated in advance is adopted, the curing performance of SiC slurry can be improved, the resin can be burnt out in the heat treatment stage, and the performance of a final finished product cannot be additionally influenced.
本发明公开了一种高固化能力的陶瓷3D打印膏料，按重量份数，包括以下组分：光敏树脂25‑45份，SiC粉体30‑60份，分散剂0.5‑2.8份，光引发剂0.1‑0.5份，抗沉降剂0.2‑1份，无水乙醇25‑35份；所述光敏树脂为单官能团树脂单体和双官能团树脂单体的混合液，所述单官能团树脂单体和双官能团树脂单体的质量比为0.5‑1：2‑4。本发明还提供了上述陶瓷3D打印膏料的制备方法。这种高固化能力的陶瓷3D打印膏料，采用粉体包裹树脂提前预活化的方式，既能提升SiC浆料的固化性能，而且树脂也会在热处理阶段被烧掉，不会对最终的成品件性能有额外的影响。
