Abstract

A preparation method for a carbon-aluminium composite material is characterized by comprising: taking phenolic resin, 99% alcohol, urotropine and oleic acid, adding into a stirred vessel, and stirring to prepare a phenolic-resin bonding agent mixed solution; adding aluminium powder, carbon black powder, pitch coke powder and needle-type coke powder, kneading, heating, adding the phenolic-resin bonding agent mixed solution, stirring and mixing to prepared a clinker; and cooling the clinker, grinding into a powder, performing compression molding, pressing molding and fixing processing, deburring, cleaning, airing or blowing with hot air to dry, so as to obtain a finished product. According to the method, a two-stage pressing progress is employed, so that porosity in a press is reduced, the press density is improved, the strength and the wear resistance of the product are improved, pores distribution is uniform, creep property of the product is reduced, deformation of the product during production is small, and the product precision is improved. By employing the advanced kneading technology, resin usage amount is reduced, product thermal conductivity is improved, so that hot-press carbon-aluminium product quality is improved, and the manufactured carbon-aluminium composite material has relatively wide purpose.

Description

technical field [0001] The invention relates to a method for manufacturing a carbon-aluminum composite material, specifically belonging to the technical field of non-metallic materials. Background technique [0002] Carbon-aluminum material products formed by hot pressing with resin as a binder are called hot-pressed carbon-aluminum products. They have been used in industrial production as carbon materials for machinery. They have a history of more than 50 years in our country. The application of carbon materials was earlier, and there is still a broad market. Hot-pressed carbon-aluminum materials are favored by manufacturers and users due to sufficient raw and auxiliary materials, reasonable prices, and simple manufacturing processes, which are suitable for mass production. As a binder, resin has relatively large performance limitations, and the performance of the product is basically the same as that of resin. Compared with sintered carbon-aluminum materials, it has the fo...
