Preparation method of room-temperature reinforcer for ceramic core, room-temperature reinforcer and reinforcing method
The invention discloses a preparation method of a room-temperature enhancer for a ceramic core, the room-temperature enhancer and an enhancing method. The preparation method comprises the following steps: mixing liquid phenolic resin and absolute ethyl alcohol according to a volume ratio of (90-98): (10-2) to obtain a phenolic resin solution; mixing the phenolic resin solution and industrial alcohol according to the volume ratio of 1: (1-2), and stirring until the mixture is uniform and free of layering, so as to obtain the room-temperature reinforcer of the ceramic core; the ceramic core is immersed in the room-temperature strengthening agent and kept for 40-60 min; taking out the ceramic core, removing the redundant room-temperature reinforcer on the surface of the ceramic core, and naturally drying the ceramic core in a room-temperature environment for not less than 12 hours; the ceramic core is placed at the first temperature higher than the room temperature environment to be dried for the first time; and drying the ceramic core at a second temperature higher than the first temperature for a second time. According to the invention, cheap raw materials and a simple formula are selected, the room-temperature bending strength of the ceramic core is greatly improved, the operation is simple and convenient, and the production efficiency is high.
本发明公开了一种陶瓷型芯的室温强化剂的制备方法及室温强化剂及强化方法，包括：液态酚醛树脂和无水乙醇按体积比90～98:10～2混合配置得到酚醛树脂溶液；酚醛树脂溶液和工业酒精按体积比1:1～2混合配置，搅拌至均匀无分层，即得陶瓷型芯的室温强化剂；将陶瓷型芯浸没于室温强化剂内保持40～60min；取出陶瓷型芯，去除陶瓷型芯的表面的多余的室温强化剂，将陶瓷型芯置于室温环境中自然干燥不少于12h；将陶瓷型芯置于高于室温环境的第一温度下烘干第一时间；将陶瓷型芯置于高于第一温度的第二温度下烘干第二时间。本发明选用价格低廉的原料和简易的配方，大幅度的提高陶瓷型芯室温抗弯强度，操作简便，生产效率高。
