介绍了Al-Mg合金压铸涂料的特点、原材料选择、涂料配方设计及制备工艺。采用通用耐火骨料、载液、悬浮稳定剂、粘结剂、分散剂及其他配料,按一定配比,加入容器中,用高速剪切机分散1h,制备得到耐高温涂料。将分散均匀的涂料与水按照1∶50的比例稀释后,加入到高压涂料喷枪,震荡后制成可现场使用的压铸涂料。该涂料具有良好的悬浮性、涂覆性、润滑性和附着强度,可以延长模具使用寿命,缩短生产周期。
The characteristics of Al-Mg alloy die-casting coating, the selection of raw materials, the formulation design and preparation process of the coating are introduced. Using universal fire-resistant aggregate, carrier fluid, suspension stabilizer, binder, dispersant and other ingredients, according to a certain ratio, added to the container, high-speed shearing machine dispersion 1h, prepared by high temperature coating. The evenly dispersed paint and water diluted according to the ratio of 1:50, was added to the high-pressure coating gun, shock made of castable coatings can be used on site. The coating has good suspension, coating, lubrication and adhesion strength, can extend the service life of mold, shorten the production cycle.
