Abstract

The invention discloses a non-phosphorus degreasing agent. The non-phosphorus degreasing agent is mixed solution prepared from the following components, wherein each liter of the mixed solution comprises the following components in part by weight: 2.0 to 4.0 grams of fatty alcohol-polyoxyethylene ether sodium sulfate, 4.0 to 6.0 grams of nonylphenol polyoxyethylene ether, 4.0 to 5.0 grams of fatty alcohol-polyoxy alkyl ether, 3.0 to 4.0 grams of fatty alcohol-polyoxyethylene ether, 2.0 to 4.0 grams of lauryl sodium sulfate, 2.0 to 3.5 grams of isopropanol, 0.1 to 0.12 gram of ethylene diaminetetraacetic acid, 1 to 2 grams of alkaline lipase and the balance of water. When the non-phosphorus degreasing agent is used for degreasing the metal, the non-phosphorus degreasing agent reduces the adsorbability of an active agent to the metal body, facilitates subsequent processing of the metal, has high degreasing speed, shortens degreasing time, improves working efficiency and is non-phosphorus and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of metal surface degreasing, in particular to a phosphorus-free degreasing agent and a preparation method thereof. Background technique [0002] Most of the traditional degreasing agents are a combination of high foaming surfactants. Although it has better degreasing effect. However, due to the active agent itself, it is often adsorbed on the surface of the metal body, which has a greater adverse effect on the subsequent process. And the general degreasing time is longer, this formula uses a variety of active agents to compound. Minimize the adsorption of the active agent and the metal body, reducing the adverse effects on the subsequent process. At the same time, this formula introduces biological enzyme active substances, which minimizes the degreasing time. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a phosphorus-free degreasing a...
