AI Technical Summary

Technical Problem

Existing metal cleaning agents pose health risks, cause environmental pollution, and have poor cleaning effects, especially in high-voltage/ultra-high-voltage insulating components where they fail to meet the required cleanliness.

Method used

A water-based metal cleaning agent is used, which contains a combination of nonionic surfactant A, nonionic surfactant B, isooctanol polyoxyethylene ether phosphate and chelating agent. By optimizing the component ratio and preparation method, a cleaning agent with excellent cleaning effect, low foaming and easy rinsing is formed.

Benefits of technology

It achieves efficient cleaning of metal surfaces, reduces foam formation, and improves the stability and safety of the cleaning agent. It is suitable for cleaning high-voltage/ultra-high-voltage electrical insulation components and meets environmental protection requirements.

Abstract

The invention discloses a water-based metal cleaning agent as well as a preparation method and application thereof. The water-based metal cleaning agent comprises water, a preservative and the following preparation raw materials in percentage by mass: 0.1%-0.3% of a nonionic surfactant A, 4%-6% of a nonionic surfactant B, 0.2%-0.5% of isooctyl alcohol polyoxyethylene ether phosphate and 1%-3% of a chelating agent, the nonionic surfactant A is selected from at least one of nonylphenol polyoxyethylene ether and octylphenol polyoxyethylene ether, and the number of oxyethylene units in the molecular structure is 6-8; the nonionic surfactant B is selected from at least one of cocoanut fatty acid diethanolamide and cocoanut fatty acid monoethanolamide. The cleaning agent has excellent metal surface cleaning capability, good low-foaming property and easy rinsing property. The invention further provides a preparation method and application of the water-based metal cleaning agent.
