A kind of neutral environment-friendly hardware cleaning agent and preparation method thereof

Abstract

The invention discloses a neutral environment-friendly hardware cleaning agent and a preparation method thereof. The cleaning agent includes 17-29 parts of complexing agents combined with sodium polyphosphate, sodium phytate, potassium oxalate and triethanolamine, 8-10 parts of saponin liquid, 1-2 parts of aloe vera gel, and 2-methylborane 4 parts, 5-7 parts of glucose, 1-5 parts of hydrazine hydrate, and the rest are deionized water. The aloe vera gel needs to be peeled to prepare an extract, and the basic sequence of adding a strong reducing agent and a solution with a foaming effect after solidification is adopted, and each component is mixed to prepare, and the pH of the cleaning agent is adjusted by dropwise addition of acid and alkali to 6.5 ‑7.5. This cleaning agent is neutral and can replace the sandblasting, strong acid pickling and other methods to remove rust on hardware, without hydrogen permeation and excessive reduction to the substrate, and maintaining the mechanical stability of the substrate; the surface active agent in the cleaning agent The synergistic effect of the cleaning agent, the reducing agent and the complexing agent has excellent rust removal effect and has the function of rust inhibition; the cleaning agent is simple to use, has a short soaking time, is safe to operate, and can be effectively recycled.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a neutral environment-friendly hardware cleaning agent and a preparation method thereof. Background technique [0002] Metal hardware should be degreased, derusted and oxidized before electroplating and spray protection to improve the bonding between the coating and the substrate. The main methods to remove oxidation rust are mechanical, pickling and other methods. Mechanical derusting has disadvantages such as loud noise, high dust, and dead angles due to uneven shaped parts; pickling mainly includes hydrochloric acid, sulfuric acid, phosphoric acid, etc., and corrosion inhibitors, surfactants, etc. are added, and the disadvantages are large smoke, poor safety, and corrosiveness. Strong, the resulting sewage treatment is difficult; in addition, the pickling method will inevitably cause serious hydrogen permeation of the base material, damage the mechanical properties of...
