The invention discloses a new low-cost mirror aluminium production process, which comprises the following steps: (1) first trimming the grinding surface in the grinding disc of the grinder with a cutter; (2) taking aluminium plate and coating the surface of the aluminium plate with a grinding fluid, the mass fraction of nano-cerium oxide in the grinding fluid is 5 to 15%. Then, the aluminium plate is placed on the grinding surface of the step (1) and carried out under the pressure of 2 Kg. The mirror aluminium of the invention is prepared by grinding. The grinding fluid also contains 5 20% weak acid, 15 35% inorganic salt and residual water by mass fraction. The production process of mirror aluminium prepared by the invention is simple, does not need silver plating, greatly reduces the production cost and simplifies the production process, overcomes the problems of light decay and dead lamp of silver plated mirror aluminium; under the same light source condition, the reflectivity of mirror aluminium prepared by the invention is 92 to 93%. In the application of LED, for example, as a reflector plate, the mirror aluminium prepared by the invention can completely replace the silver plated mirror. Surface aluminium.

一种新的低成本镜面铝的生产工艺
本专利技术属于铝的加工领域,特别涉及一种新的低成本镜面铝的生产工艺。
技术介绍
镜面铝板是指通过轧延、打磨等多种方法处理,使铝板材表面呈现镜面效果。镜面铝板被广泛应用于照明灯具反射板及灯具装饰、太阳能集热反光材料、室内建筑装饰、外墙装饰、家用电器面板、电子产品外壳、家具厨房、汽车内外装饰、标牌、标识、箱包、首饰盒等领域。目前市场上出售的镜面铝仅由德国,意大利以及国内共三家工厂生产,其生产工艺是:铝板经过抛光、电镀介质层和电镀银来实现。这种生产工艺因其复杂性和生产环境要求苛刻,致使其生产成本很高。且由于工序多,过程长,在生产过程中无法避免生产的环境因素给生产过程带来坏的影响,例如灰尘,划伤,碰伤等影响因素。因为镜面铝用来做线路板基材主要是使用其反光面起到反光作用,目前的镜面铝反光是通过所镀银层实现,银层很易出现受伤,在使用环境中很易受到环境中的硫侵蚀,造成银层进一步破坏,出现银层发黑,产生光衰,最终死灯,无法达到反光的效果,至使产品失效。因此,为了避免银层破坏而出现光衰和死灯现象,也为了降低镜面铝的生产成本,提供一种新的低成本镜面铝的 ...
