Low-cost ferrite bonding special rubber powder and dry-pressing magnetic tile preparation process thereof
The invention relates to the technical field of sintered ferrites, and discloses a low-cost ferrite bonding special rubber powder and a dry-pressing magnetic tile preparation process thereof. According to the technology, (1) a binder is selectedto replace solid camphor used all the time; (2) the optimized rubber powder formula meets the requirements of high performance and high strength of the product, and the high strength is improved by (Rockwell hardness) HRC 1.8 compared with the same product bonded by camphor; (3) the powder dispersibility and consistency of the aerosol method glue mixingprocess are good, and the product molding density is improved; (4) the feeding parameters, the pressure maintaining parameters, the pressure relieving parameters, the ejection cylinder slight retreating parameters, the ejection cylinder static parameters and the like of the forming press are adjusted, and the product consistency and the pressing density are improved; and (5) sintering process parameters are optimized, and a pipeline for exhausting air and discharging moisture in a preheating area is additionally arranged, so that the product is free of cracking. According to the low-cost ferrite bonding special rubber powder and the dry-pressed magnetic tile preparation process thereof, the product manufacturing cost is reduced by 7.87%, the clean production of sintered ferrite dry-pressed magnetic shoes is realized, the application is environment-friendly, and the economic and social benefits are remarkable.
本发明涉及烧结铁氧体技术领域，且公开了一种低成本铁氧体粘结特种胶粉及其干压磁瓦制备工艺，包括以下步骤：（1）优选粘结剂，取代一直以来使用的固体樟脑；（2）优化胶粉配方满足了产品高性能和高强度，所述高强度相比樟脑粘结的同产品提高(洛氏硬度)HRC1.8；（3）气雾法混胶工艺粉末分散性、一致性好,提高了产品成型密度；（4）调整成型压机的送料参数，保压、缷压参数和顶缸微退、顶缸静止参数等，提高了产品一致性和压制密度；（5）优化烧结工艺参数，增设对预热区抽气排湿管道，产品无开裂。该一种低成本铁氧体粘结特种胶粉及其干压磁瓦制备工艺，产品制造成本下降7.87%，实现了烧结铁氧体干压磁瓦清洁生产、应用环保，经济效益社会效益显著。
