Binder for jet printing of silicon carbide ceramic part as well as preparation method and application of binder
The invention belongs to the related technical field of additive manufacturing, and discloses a binder for jet printing of a silicon carbide ceramic part and a preparation method and application thereof, the binder comprises the following components in parts: 10-20 parts of carbon black dispersion slurry, 50-60 parts of thermosetting resin, 0.5-2 parts of a wetting agent, 0.1-0.3 part of a bactericide, 5-10 parts of a humectant and 7.7-34.4 parts of an organic solvent. The binder contains carbon black, so that when the binder is radiated by infrared rays after spraying is finished, the carbon black has good radiation absorption capacity, the temperature of a forming area is rapidly increased through the photo-thermal conversion effect, thermoset in the binder can be promoted to be vertically heated and cured in a short time, and the bonding strength of powder in the forming area is improved; and powder in a forming area is prevented from deviating due to overlarge pressure during powder spreading of the roller. And meanwhile, carbon black in the binder can generate secondary silicon carbide in the siliconizing reaction sintering link, and the density of a formed part is increased.
本发明属于增材制造相关技术领域，其公开了一种用于喷射打印碳化硅陶瓷件的粘结剂及其制备方法与应用，所述粘结剂包括以下份数的组分：10～20份炭黑分散浆料、50～60份热固性树脂、0.5～2份润湿剂、0.1～0.3份杀菌剂、5～10份保湿剂及7.7～34.4份有机溶剂。所述粘结剂含有炭黑，如此使得粘结剂在喷射结束后被红外辐射时，炭黑具有较好的辐射吸收能力，其通过光热转化作用使得成形区域温度迅速升高，短时间内可以促使粘结剂中的热固性竖直升温固化，增加了成形区粉末的粘结强度，防止辊轮铺粉时压力过大使成形区粉末发生偏移。同时，粘结剂中的炭黑在渗硅反应烧结环节可以生成二次碳化硅，增加了成形件的致密度。
