Two-stage reinforced ceramic binder for 3DP printing and preparation method of two-stage reinforced ceramic binder
The invention relates to a two-stage reinforced ceramic binder for 3DP printing and a preparation method of the two-stage reinforced ceramic binder. The binder is an organic binder. According to the two-stage reinforcement principle of thermocuring and photocuring, the bonding strength of the adhesive to ceramic powder is remarkably improved, the solid content in a green body is further reduced, the green body is not prone to diffusion on a powder bed, and after being formed and cured, the green body can keep high strength and is convenient to clean and transport; and during degreasing and sintering, the constant shrinkage ratio is easily kept, collapse and deformation are not likely to happen, and finally a degreased and sintered sample piece has high density.
本发明涉及一种用于3DP打印的二段式增强陶瓷粘结剂及其制备方法，所述粘结剂为有机粘结剂。本发明通过热固化与光固化二段式增强原理，使粘结剂对陶瓷粉末的粘结强度显著提升，进一步降低生坯中固含量，且在粉床上不易扩散，成型固化后，生坯可保持高强度，便于清理、运输；在进行脱脂、烧结时，易保持恒定的收缩比，且不易坍塌、变形，最终使脱脂烧结样件具有较高的致密度。
