Abstract

The invention discloses a phosphorus-free water-based metal cleaning agent and a preparation method thereof. The cleaning agent is composed by, by weight, 4-6 parts of fluorocarbon surfactant, 15-20 parts of sodium dodecyl benzene sulfonate, 3-8 parts of polyethylene glycol, 3-5 parts of triethanolamine, 1-2 parts of a metal chelating agent, 3-5 parts of a builder, 2-4 parts of a corrosion inhibitor, 2-4 parts of a defoaming agent and 100-120 parts of water. The phosphorus-free water-based metal cleaning agent is scientific and reasonable in composition, wide in raw material source and excellent in degreasing capacity, low-foaming performance and dispersive capacity; the degreasing rate reaches 96% or above; harmful substances such as phosphorus and nitrite are not included; and the phosphorus-free water-based metal cleaning agent is safe, environmentally friendly and wide in application scope.

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 water-based metal cleaning agent. Background technique [0002] In industrial production, whether it is the processing and assembly of parts, or heat treatment, electroplating, and product packaging and unsealing, the metal surface must be cleaned; large machinery such as vehicles and ships are prone to oil and dust, in order to improve coating adhesion and durability Corrosion, the metal surface must be degreased and degreased before painting. Cleaning oil and rust is the primary process of metal surface pretreatment, and the quality of metal surface treatment is closely related to the cleaning effect of oil and rust. At present, industrial cleaning agents can be roughly divided into water-based cleaning agents, semi-aqueous-based cleaning agents, and solvent-based cleaning agents according to their components. Among th...
