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 comprises 17-29 parts of a complexing agent composed of sodium polyphosphate, sodium phytate, potassium oxalate and triethanolamine, 8-10 parts of saponin extract, 1-2 parts of aloe gel, 2-4 parts of methyl borane, 5-7 parts of glucose, 1-5 parts of hydrazine hydrateand the rest deionized water. The extract is prepared after aloe is peeled, the solid, liquid, a strong reducing agent and a solution with the blistering effect are sequentially added in the basic sequence, all the components are mixed for preparation, and acid and alkaline are dropwise added so that the PH value of the cleaning agent can be adjusted to 6.5-7.5. The cleaning agent is neutral and can completely replace the sand blasting mode, the strong acid pickling mode and other modes to remove rust on hardware, a matrix is free of the hydrogen permeation phenomenon and overreduction, and the mechanical stability of the matrix is kept; a surfactant, the reducing agent and the complexing agent in the cleaning agent cooperate, the rust removal effect is good, and the rust resistance function is achieved; and a using method of the cleaning agent is simple, the soaking time is short, operation is safe, and the cleaning agent 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...
