Abstract

The invention relates to a metal surface degreasing agent. The metal surface degreasing agent is composed of an agent A and an agent B. The agent A is prepared from, by mass percent, 20%-30% of phosphate, 1%-10% of carbonate, 5%-15% of silicate, 1%-5% of a chelating agent, 1%-10% of a solubilizer and 30%-72% of deionized water. The agent B is a surface active agent. An aluminum material and an aluminum alloy subjected to degreasing and acid pickling can react with a passivation solution or a phosphating solution especially easily, a uniform and thin passivation film is formed, subsequent sealing treatment is facilitated better, and the salt mist resisting time of the passivation film is prolonged. The metal surface degreasing agent has the beneficial effects that operation is easy, no corrosion is generated, the treatment temperature is low, cost is low, and little foam is generated; and spraying and soaking can be both achieved in any place.

Description

technical field [0001] The invention belongs to the technical field of metal degreasing and degreasing, and in particular relates to a metal surface degreasing agent, its preparation method and application. technical background [0002] The first process before aluminum and aluminum alloys enter the production line for surface treatment is degreasing. After the aluminum surface is exposed to grease or pollutants, it will hinder its surface from fully contacting with the treatment solution, and it is impossible to obtain a uniformly wet and clean surface. ; If grease or pollutants are brought into the subsequent treatment solution, it will destroy the composition of the solution and form secondary pollution to the aluminum material. Lubricants, emulsions, rolling oils or cutting fluids used in the production process of aluminum materials, polishing pastes used in mechanical polishing, anti-rust oils used in the storage of semi-finished products (substrates) and other necessar...
