Preparation method of silicon nitride antenna housing and silicon nitride antenna housing
The invention relates to the technical field of radomes, in particular to a preparation method of a silicon nitride radome and the silicon nitride radome. When the raw materials are mixed, the following steps are adopted: mixing a part of photosensitive resin with a photoinitiator to form a photosensitive resin mixed solution A; mixing the residual photosensitive resin with an oxygen inhibitor to form a photosensitive resin mixed solution B; and homogenizing and mixing the photosensitive resin mixed solution A, the photosensitive resin mixed solution B, silicon nitride powder and a sintering aid to form the silicon nitride ceramic slurry. The oxygen inhibitor is introduced in the preparation of the silicon nitride antenna housing to improve the curing depth of the silicon nitride ceramic slurry, so that the printing time is greatly shortened, the printing efficiency is improved, and the production time cost is reduced; the problem of low yield caused by high curing depth in the prior art is solved while the curing depth is improved; the silicon nitride antenna housing prepared by the preparation method is integrally formed, subsequent processing is not needed, and operation steps are reduced.
本发明涉及天线罩技术领域，尤其涉及氮化硅天线罩的制备方法及氮化硅天线罩，原材料还含有阻氧剂；将原材料混合时采用如下步骤：取部分光敏树脂与光引发剂进行混合，形成光敏树脂混合A液；取剩余光敏树脂与阻氧剂进行混合，形成光敏树脂混合B液；将光敏树脂混合A液、光敏树脂混合B液、氮化硅粉体和烧结助剂均质混合，形成氮化硅陶瓷浆料。本发明在氮化硅天线罩的制备中引入阻氧剂以提高氮化硅陶瓷浆料的固化深度，极大的缩短了打印时间，提高打印效率，降低生产时间成本；在提高固化深度的同时，克服了现有高固化深度导致的的良品率低的问题；由本制备方法制备的氮化硅天线罩一体化成型，无需后续加工，减少操作步骤。
