Problems solved by technology

[0003] Because aluminum itself is relatively active, the existing cleaning agents usually use highly acidic or alkaline cleaning solutions in order to have a good cleaning effect. In this way, the cleaning process is more corrosive to aluminum, which to a certain extent causes aluminum Loss
[0004] In addition, in the prior art, phosphate is often used as a builder in cleaning agents due to its good cleaning effect and the effect of buffering pH value, but because phosphate will directly promote the proliferation of microorganisms in water, excessive consumption of oxygen in water, phosphate The discharge and accumulation of pollutants will pollute the water quality of rivers, lakes and seas, affect the survival of aquatic organisms and animals, and destroy the ecological balance. Therefore, the discharge of phosphorus-containing wastes has been restricted by environmental protection regulations.

Abstract

The invention discloses an aluminum cleaning agent. The aluminum cleaning agent consists of the following raw materials in percentage by weight: 2-6% of potassium hydroxide, 2-10% of propanediol butyl ether, 1-5% of sodium metasilicate, 1-5% of boric acid, 1-7% of sodium polyacrylate, 1-5% of d-sorbitol solution, 0.4-1.2% of sodium chloride, 0.1-0.5% of dimethyl siloxane, 1-8% of anion surface active agent, 1-8% of nonion surface active agent, and the balance of water. The aluminum cleaning agent contains no such substances as phosphate and heavy metals harmful to human bodies and environments, is free of environmental pollution, is safe and reliable in use, is higher in cleaning efficiency, reaches the cleaning efficiency of 99%, meanwhile, is better in rust and corrosion resistance, is bright and smooth in cleaned aluminum workpieces, and is free of damaging the workpieces.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to an aluminum cleaning agent and a preparation method thereof. Background technique [0002] Aluminum is widely used in aviation, construction, transportation, electrical, chemical and other industrial fields, and its demand is second only to steel, ranking second in metal materials. During the manufacture and use of aluminum workpieces, due to mechanical processing, rust prevention, loading, storage and transportation, etc., the surface is often exposed to various oil stains based on mineral oil or animal and vegetable oil and added with various organic additives or inorganic substances. . Therefore, before the surface treatment of the aluminum material, the oil stain attached to the surface must be pretreated, that is, the surface is cleaned to remove the oil stain attached to the surface. [0003] Because aluminum itself is relatively active, the existing cleaning agen...
