Problems solved by technology

Due to the differences in components in the assembly, especially the assembly of ferrous and non-ferrous metals such as iron-aluminum, carbon steel-copper, etc., the assembly is prone to corrosion or residual spots after cleaning, which seriously affects its subsequent processing and quality
[0003] At present, the cleaning agents on the market generally have a narrow range of cleaning objects, are prone to corrosion and discoloration after cleaning, have poor cleaning ability, and have a short service life.
Spray cleaning has the disadvantages of multiple bubbles and easy clogging.
For example, patent CN 102154655A discloses an aluminum alloy room temperature spray cleaning agent and its preparation method, which can effectively avoid the phenomenon of easy rust and discoloration of aluminum alloy parts, but this patented product is not suitable for degreasing ferrous metals and other non-ferrous metals Anti-rust cleaning, etc.; patent CN101413129A discloses an anti-rust metal cleaning agent, which is suitable for mechanical automatic medium-high pressure spray cleaning and ultrasonic cleaning, and is mainly aimed at degreasing and anti-rust cleaning of ferrous metal products. Degreasing and antirust cleaning of non-ferrous metals such as copper and aluminum

Abstract

The invention discloses a spray cleaning agent for a metal assembly. The cleaning agent is prepared from polyether carboxylate, carboxylate, block polyether, an alcohol ether surfactant, sodium gluconate, diethylenetriam inepentaacetate, ethylene diamine tetraacetic acid disodium salt, sodium metasilicate, sodium benzoate, triazole, triethanolamine, alcohols, glycol ether and deionized water. The cleaning agent is applicable to the oil-removing and rust-preventing cleaning of black metals, non-ferrous metals and assemblies formed by the black metals and the non-ferrous metals, has extremely high cleaning performance and a relatively long corrosion inhibition period, cannot cause the change of the color, is environment-friendly and low-foam, does not contain substances such as phosphorus and sodium nitrite, cannot pollute the environment, is particularly applicable to the spray cleaning at normal temperature, and is low in energy consumption in the cleaning process, the residue is avoided, corrosion spots are not generated, and waste liquor of the cleaning agent is can be easily disposed. The corrosion inhibition period of a copper-aluminum assembly exceeds 10 days; the corrosion inhibition period of a brass-cast iron assembly exceeds 7 days; the corrosion inhibition period of an aluminum-cast iron assembly exceeds 7 days; and the corrosion inhibition period of a copper tin-aluminum-low-carbon steel assembly exceeds 10 days.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a metal assembly spray cleaning agent. Background technique [0002] An assembly mainly refers to a component composed of multiple parts, and the materials, components, and chemical properties of the parts may be the same or completely different. With the development of industry, the application range of assemblies in the manufacturing industry is getting wider and wider, and the cleanliness of their surfaces is getting higher and higher. Due to the differences in components in the assembly, especially the assembly of ferrous and non-ferrous metals such as iron-aluminum, carbon steel-copper, etc., the assembly is prone to corrosion or residual spots after cleaning, which seriously affects its subsequent processing and quality. [0003] Cleaning agents currently on the market generally have a narrow range of cleaning objects, are prone to corrosion and discoloration after cleaning, have poor ...
