Abstract

The invention discloses an aqueous metal antirust agent and a preparation method thereof. The aqueous metal antirust agent is prepared from following raw materials by weight: 10-20 parts of dodecylbenzenesulfonic acid, 20-30 parts of pentaerythritol tetraoleate, 40-45 parts of butyl oleate, 10-15 parts of o-toluidine, 7-15 parts of sodium sulfate, 10-20 parts of sodium hydroxide, 10-15 parts of sodium silicate and 40-50 parts of water. The aqueous metal antirust agent can be uniformly dispersed in water without impurities such as suspended solids, etc. and has good dispersity. The content of volatile organic compounds is 0.3-0.5 ppm. The content of harmful volatile compounds is low, thus having no harm to human health, and therefore the aqueous metal antirust agent is environment friendly and healthy.

Description

technical field [0001] The invention relates to a metal antirust agent, in particular to a water-based metal antirust agent and a preparation method thereof. Background technique [0002] Metal surface treatment agent refers to the general term for various chemical agents for metal surface treatment. Metal surface treatment includes degreasing, rust removal, phosphating, antirust and other substrate pretreatments, which are prepared for metal coating technology and metal protection technology. The quality of substrate pretreatment has a great influence on subsequent coating preparation and metal use. big impact. It mainly includes three categories: cleaning agent, antirust agent and phosphating solution. Metal surface treatment technology is divided into two categories: mechanical treatment (such as sandblasting, polishing, high-pressure water washing, etc.) and chemical treatment. As for coating, electroplating and other technologies, which have independently developed ...
