Abstract

The invention relates to a cleaning and rust inhibiting agent and a preparation method thereof, pertaining to chemical cleaning agent field, and the cleaning and rust inhibiting agent consists of the components: 1 to 2 percent of ethylenediamine tetraacetic acid solution, 3 to 4 percent of triethanolamine solution, 0.5 to 1 percent of eynanolamine solution, 5 to 10 percent of compound borate ester solution, 5 to 10 percent of polyacrylic acid solution, 1 to 3 percent of triazine disinfectant solution, and the other is water to be added into 100 percent. The cleaning and rust inhibiting agent is prepared through a scientific processing technology by using organic acid, surfactant and disinfectant as main materials, without needing to be rinsed after cleaning, and the surfaces of cleaned parts have no white spot and are as shiny as new ones, thus reaching the rust inhibiting requirements of a workshop. The product is weak alkaline, and has advantages of wide sources, easy acquiring, small using quantity and strong cleaning ability to such processing oil as rust inhibiting oil, emulsified oil, cutting fluid, oleostearine, transformer oil, etc., which is particularly applied to the cleaning and rust inhibiting for steel and aluminum materials.

Description

technical field [0001] The invention relates to the field of chemical cleaning agents, in particular to a cleaning and antirust agent combining cleaning and antirust and a preparation method thereof. Background technique [0002] Some aluminum or steel metal parts are inevitably polluted by oil during processing or use, and the polluted metal parts must be cleaned with cleaning agents. There are following problems in cleaning with existing cleaning agents: 1. After cleaning, some white spots caused by the cleaning agent remain on the surface of the metal parts; 2. After cleaning, rust will reappear in a short period of time. The reason for the above problems is because the existing metal cleaning agent is a water-based cleaning agent with surfactant as the main component. When there is more foam and high pressure equipment cannot be used, the cleaning efficiency is low. In addition, the existing cleaning method has complicated process steps, and generally needs three proce...
