Abstract

The invention discloses a dual-ingredient degreasing agent for a battery aluminum shell. The dual-ingredient degreasing agent consists of an agent A (a main agent) and an agent B (an assistant), wherein the agent A is prepared from the following ingredients in percentage by weight: 15-20% of anionic surfactant, 30-45% of nonionic surfactant, 10-15% of solvent and the balance of water, and the agent B is prepared from the following ingredients in percentage by weight: 50-70% of inorganic base and 30-50% of chelating agent; the anionic surfactant is one or a mixture of more of the following substances: secondary alkyl sulphonate sodium and sodium dodecylbenzensulfonate; the nonionic surfactant is one or a mixture of more of the following substances: isomeric fatty alcohol-polyoxyethylene ether and fatty alcohol-polyoxyethylene ether, wherein the number of carbon atoms of the isomeric fatty alcohol-polyoxyethylene ether is 13, and the number of EO is 7; the solvent is 2-methyl-2,4-pentanediol; the inorganic base is sodium metasilicate; and the chelating agent is a mixture of tetrasodium ethylenediamine tetraacetate, sodium citrate and sodium gluconate. The dual-ingredient degreasing agent disclosed by the invention has the advantages of high degreasing speed, little corrosiveness, large unit degreasing area and good washing power.

Description

technical field [0001] The invention relates to a two-component battery aluminum case degreasing agent and a manufacturing method and a use method thereof, which are widely used for degreasing and cleaning the battery aluminum case, and belong to the technical field of cleaning for the electronic industry. Background technique [0002] With the rapid development of the mobile phone industry at home and abroad, the demand for mobile phone batteries has also increased, which has also led to the rapid development of the aluminum case industry for mobile phone batteries. [0003] The aluminum case of the mobile phone battery (hereinafter referred to as the battery aluminum case) has a large amount of oil on the surface after stamping and forming, which brings certain difficulties to degreasing and cleaning. The battery aluminum casing industry generally has a large production capacity (100,000 to 1 million per day) and low profits. Therefore, in order to increase production cap...
