Macromolecular environment-friendly cleaning agent and preparation method thereof

Abstract

The invention discloses a macromolecular environment-friendly cleaning agent and a preparation method thereof. The macromolecular environment-friendly cleaning agent comprises the following raw materials in percentage by weight: 30-45% of isododecane, 30-40% of isohexadecane, 5-10% of polyoxypropylene ether, 3-5% of isopropyl alcohol and 5-10% of macromolecular composition, wherein the macromolecular composition is a mixture composed of a macromolecular surfactant, a macromolecular corrosion inhibitor and a macromolecular preservative. The method for preparing the macromolecular environment-friendly cleaning agent comprises the following steps: stirring the mixture composed of the macromolecular surfactant, the macromolecular corrosion inhibitor and the macromolecular preservative in a closed kettle with the normal temperature at a high speed for 30 minutes to obtain the macromolecular composition, then adding the 30-45% of isododecane, the 30-40% of isohexadecane, the 5-10% of polyoxypropylene ether and the 3-5% of isopropyl alcohol, and stirring fully and evenly to obtain the finished product. The macromolecular environment-friendly cleaning agent does not consume a self-oxidation layer, meets the green environmental protection requirements, has no corrosion to metals such as copper and aluminium and no harm to human bodies, is easily biodegradable and safe for environments and has strong dissolving capacity, excellent oil removal and degreasing capacity and stable performances.

Description

technical field [0001] The invention relates to a cleaning product, in particular to a polymer cleaning agent for cleaning metal materials. Background technique [0002] In recent years, my country's metal processing and manufacturing industry has developed rapidly and has become a "world factory", and the demand for industrial cleaning is also increasing; there are many types of cleaning agents in my country, such as fluorine, CFC, and HCFC, which all contain halogen elements. And it affects the environment. Now Shenzhen, Shanghai, Jiangsu and other big cities in China have banned it. Hydrocarbon-based, ethanol-based, and silicone-based products have low flash points, are flammable, and have great potential safety hazards. At present, in the cleaning process of military enterprises, No. 180 washing gasoline and kerosene are mostly used as degreasing and decontaminating cleaning agents. However, because 180 washing gasoline is flammable and explosive, gasoline and air can for...

[0002] In recent years, my country's metal processing and manufacturing industry has developed rapidly and has become a "world factory", and the demand for industrial cleaning is also increasing; there are many types of cleaning agents in my country, such as fluorine, CFC, and HCFC, which all contain halogen elements. And it affects the environment. It has been banned in major cities such as Shenzhen, Shanghai, and Jiangsu. Hydrocarbons, ethanols, and silicones have low flash points, are flammable, and have great potential safety hazards.

At present, in the cleaning process of military enterprises, No. 180 washing gasoline and kerosene are mostly used as degreasing and decontaminating cleaning agents. However, because 180 washing gasoline is flammable and explosive, gasoline and air can form explosive mixtures, which can cause explosions when exposed to open flames and high heat. , can also cause combustion and explosion due to static spark discharge, and there is a great potential safety hazard

No. 180 washing gasoline is easy to rust in the humid air. Cast iron and cast steel products are easy to rust, and aluminum-magnesium alloy products are easy to corrode, which will cause certain losses to the enterprise.

Moreover, existing cleaning agents contain chloride ions, iodide ions, fluoride ions, and bromide ions, because chloride ions can cause cracks and deformations in titanium alloy materials, and aluminum-magnesium alloy materials are prone to corrosion in humid seasons. The cleaning agent volatiles affect the atmosphere, which is not conducive to environmental protection
