Abstract

The invention relates to a phosphorus-free rust-proof metal cleaning agent and a preparation method thereof. The phosphorus-free rust-proof metal cleaning agent is composed of the following raw materials by weight: 10-15 parts of a non-ionic surfactant fatty alcohol polyoxyethylene ether, 10-15 parts of coconut fatty acid diethanolamide, 5-10 parts of an anionic surfactant sodium dodecylbenzene sulfonate, 10-15 parts of a washing assistant, 8-12 parts of a chelating agent, 2-5 parts of a rust and corrosion inhibitor, 1-4 parts of a defoaming agent and 80-100 parts of water. The phosphorus-freerust-proof metal cleaning agent provided by the design has the advantages of low price and wide sources of components, simple operation, good solubility, excellent detergency, low foaming performance, and no damage or corrosion to metal parts and the like; and more importantly, the metal cleaning agent does not contain phosphorus, nitrite, heavy metals and other harmful substances and the surfactants can be biodegraded, so subsequent sewage treatment is facilitated, and safety and environmental protection are obtained.

Description

technical field [0001] The invention belongs to the field of industrial cleaning, and relates to a metal cleaning agent, in particular to a phosphorus-free antirust cleaning agent and a preparation method thereof. Background technique [0002] Metal cleaning is one of the indispensable processes in mechanical processing and production. According to patent documents and market research, most of them are aimed at the cleaning of oil and rust on the surface of machinery and equipment. The cleaning effect is not high; the metal surface is rusted during the cleaning process; some The cleaning agent also contains harmful substances such as nitrite, which is harmful to the environment and people's health. With the advancement of fine organic synthesis technology, biotechnology, detection technology and other related technologies, chemical cleaning technology has also been developed and is developing in the direction of "green" environmental protection. Phosphorus-free and fluorine...
