【摘要】：通過(guò)在水基AM-MBAM-YSZ漿料中加入水溶性高分子PEG,并將可反應(yīng)單體與引發(fā)劑分離,制備了固相含量為52vol%,室溫下可穩(wěn)定儲(chǔ)存數(shù)天、混合后固化可控的雙組份打印漿料。漿料粘度為11.2 Pa·s(剪切速率100s-1),屈服應(yīng)力為510.7 Pa,漿料打印的線條尺寸均勻、邊緣平整,坯體表面無(wú)剝離,燒結(jié)后顯微結(jié)構(gòu)均勻致密。打印線條燒結(jié)后的相對(duì)密度為99.3%,圓柱試樣燒結(jié)后的相對(duì)密度為95.6%。
[Abstract]:The water-soluble high-molecular PEG was added to the water-based AM-MBAM-YSZ slurry, and the reactive monomer was separated from the initiator to prepare the two-component printing slurry with the solid phase content of 52 vol% and stable storage for several days at room temperature. The viscosity of the slurry is 11.2 Pa.s (shear rate 100s-1), the yield stress is 510.7Pa, the size of the line printed by the slurry is uniform, the edge is flat, the surface of the blank is not stripped, and the microstructure is even and compact after sintering. The relative density of the printed line after sintering is 99.3%, and the relative density after the sintering of the cylindrical sample is 95.6%.
