Ceramic core room temperature reinforcing agent and reinforcing process
The invention provides a ceramic core room temperature reinforcer and a reinforcement process, the reinforcer is mainly prepared by mixing epoxy resin, anhydride and propylene glycol methyl ether cellulose acetate, and in the reinforcement process, absolute ethyl alcohol is adopted to clean residual reinforcement liquid on the surface of a core. The purpose of room-temperature strengthening can be stably achieved for a long time, the strength of the ceramic core strengthened through the strengthening technology is improved by 3-4 times, mechanical damage in the transportation process can be avoided, and the impact resistance of the ceramic core to high-pressure and high-speed wax liquid is improved. The reinforcing agent is simple in formula, environmentally friendly and capable of being repeatedly used, the reinforcing process is convenient to operate, and the qualification rate and the production efficiency of the ceramic core are effectively improved.
本发明提供了一种陶瓷型芯室温强化剂及强化工艺，所述强化剂主要由环氧树脂、酸酐和丙二醇甲醚醋酸纤维酯混合配制而成，并在强化工艺中采用无水乙醇清洗型芯表面残留的强化液。本发明可长期、稳定实现室温强化的目的，采用本发明所述强化工艺强化后的陶瓷型芯，其强度提升3～4倍，能够避免运输过程中的机械损伤，以及提高陶瓷型芯对高压、高速蜡液的抗冲击性。本发明中强化剂配方简单、环保、可重复多次使用，强化工艺操作方便，有效提高了陶瓷型芯的合格率和生产效率。
