Abstract

The invention relates to an aluminum product cleaning agent and a preparation method thereof. The preparation method includes: (1) sequentially putting partial of water, sorbitol, dimethyl dodecyl amine oxide, sodium dodecyl benzene sulfonate and lauryl sodium sulfate into a reaction kettle, and fully stirring the solution until the mixture is totally dissolved to obtain mixture A for spare; (2) sequentially putting the remaining water, NaOH, NaCl and sodium silicate into the reaction kettle, stirring the solution until the mixture is totally dissolved to obtain mixture B; and (3) cooling the mixture B to the room temperature, adding the mixture A in the mixture B, and fully stirring until the solution is even to obtain the finished product of the aluminum product cleaning agent. The aluminum product cleaning agent has strong cleaning capability and can thoroughly clean oil dirt, the oil dirt is small in corrosion, an oxidation film on the surface of an aluminum product cannot be damaged, the glossiness of an aluminum part is maintained, and the aluminum part is free of watermarks, spots and residual dirt and is non-discoloring.

Description

technical field [0001] The invention belongs to the field of metal cleaning agents, in particular to an aluminum product cleaning agent and a preparation method thereof. Background technique [0002] Aluminum is the most abundant metal element in the earth's crust, and it is the second largest group of metals after steel. Aluminum and its alloy products have been widely used in aviation, construction, automobile, refrigeration and other industries due to their good ductility, plasticity, electrical conductivity, thermal conductivity and corrosion resistance. Since the surface of aluminum products is easily polluted by various oils and dusts during manufacture and use, regular cleaning is required. However, the existing cleaning agents for aluminum products still have many deficiencies, such as: poor cleaning ability, oil stains and watermarks after cleaning; high alkalinity of the product, excessive corrosion to aluminum products; phosphorus and heavy metals, which are not ...
