Abstract

The invention discloses casting welding line polishing paste and relates to the technical field of polishing agents. The casting welding line polishing paste is prepared from the following raw materials in parts by weight: 25 to 30 parts of aluminum oxide powder, 10 to 15 parts of nano ceramic powder, 8 to 12 parts of activated clay, 6 to 10 parts of a wax auxiliary agent, 6 to 10 parts of hydrogenated castor oil, 5 to 8 parts of chlorinated paraffin, 5 to 8 parts of sepiolite powder, 4 to 6 parts of butadiene rubber, 3 to 5 parts of polyvinyl chloride resin, 3 to 5 parts of polyacrylamide, 2 to 3 parts of petroleum sodium sulfonate, 1 to 2 parts of barium stearate and 50 to 70 parts of paraffin oil. The polishing paste has proper viscosity, is transparent and clear, and is convenient to use; in a polishing process, the polishing paste has a certain lubricating effect, so that the polishing precision and the surface quality of castings are effectively improved; the polishing paste has an excellent rust-proof effect and can prevent wound surfaces, caused by polishing, from a rusting phenomenon under the action of oxygen, moisture and other corrosives.

Description

Technical field: [0001] The invention relates to the technical field of polishing agents, in particular to a casting welding seam polishing paste. Background technique: [0002] Castings are metal forming objects obtained by various casting methods, that is, the smelted liquid metal is injected into the pre-prepared casting mold by pouring, injection, suction or other casting methods, and after cooling, after grinding and other subsequent processing methods. , the resulting object of certain shape, size and properties. Due to the excellent performance of castings, they occupy a large proportion of automobile manufacturing materials, especially some basic parts with high machining accuracy and high prices, such as cylinder heads, cylinder blocks, transmission housings, etc. In the process of manufacturing and use of castings, cracks, pores, damage, etc. often occur, and welding treatment is required. Due to the high carbon content and many impurities in the casting, and the...
