Problems solved by technology

However, because the aluminum alloy material is relatively soft compared to traditional glass and other materials, and because the aluminum alloy contains other metal components, it is difficult to obtain a high-quality polished surface with traditional polishing
However, the method of plating nickel-phosphorus metal layer on the surface will bring "bimetal effect", which restricts the application of aluminum alloy reflectors in space systems

Abstract

The invention provides a polishing solution which is prepared from the following components in parts by weight: 75-80 parts of water-based carrier liquid; 3-5 parts of polishing powder; 5-10 parts of a surfactant; 0.5-5 parts of an oxidizing agent; 0.2-0.4 part of a pH regulator; and 0.1-0.3 part of a defoaming agent. The polishing powder is alumina particles; the surfactant is polyhydric alcohol and alcohol ammonium salt; the oxidant is hydrogen peroxide; the pH regulator is sodium carbonate and organic acid; the defoaming agent is a polyether defoaming agent. The polishing performance of the polishing solution is not affected by the polishing time, deterministic removal can be carried out on the metal surface according to the machining path and the planning time, and rapid improvement of the surface shape precision is achieved. Besides, the polishing solution is simple in preparation method, safe, pollution-free, low in cost and easy to clean, and raw materials are easy to obtain.

Description

technical field [0001] The invention belongs to the field of metal surface processing, and in particular relates to a polishing liquid for polishing metal materials, a polishing disc and a polishing method. Background technique [0002] The content of aluminum in the earth's crust is second only to oxygen and silicon, and is the most abundant metal element in the earth's crust. Aluminum alloys have very high reflectivity over a broad spectral range of infrared, visible, and all the way into ultraviolet light, making them a good choice for multispectral imaging applications. Aluminum products and aluminum alloy products have the characteristics of high specific stiffness, high specific modulus, light weight, good ductility, good thermal conductivity, and strong corrosion resistance. It is widely used in hardware. [0003] At present, aluminum alloy reflectors are mostly processed by single-point diamond turning, but the surface precision after turning can only reach the mic...
