Problems solved by technology

However, there are differences between the three products in the cleaning process
The first product has a relatively high content of surfactant, and the foam is very thick during use. During the spraying process, it can only be sprayed on the outer surface of the air conditioner cooling fins, and it needs to be wiped manually to clean it, while the inner cooling fins not being cleaned well
The second product does not have the foam to hinder the cleaning of the inner heat sink, making the cleaning process simple and easy. However, pure solvents are known to be very flammable, so this type of air conditioner cleaning aerosol is dangerous during storage and use. people pose a safety hazard
However, according to the air conditioner cleaning agent composition described in this patent, we found that the air conditioner cleaning agent used more surfactants, which caused the product to generate a lot of foam during use, which increased the heat dissipation of the cleaning agent in the air conditioner. The residue on the fins is not good for the air conditioner
In addition, the air conditioner cleaning agent composition described in this patent lacks a reliable corrosion inhibition system, resulting in the risk of rusting and bursting of the finished aerosol product during storage
[0007] Water-based aerosols have always had the problem of corrosion in aerosol cans, which has brought safety hazards to factories and consumers
In order to solve this problem, people try to improve the purity of water and control the means of raw material impurities, but they have not obtained better results.

Abstract

The invention discloses a cleaning aerosol composition for a household air conditioner and a preparation method thereof. The cleaning aerosol composition for the household air conditioner contains the main ingredients in percentage by weight: 30-70% of softened water, 0.01-0.5% of surfactant, 0.01-15% of acrylic (acrylate) copolymer, 0.05-0.5% of composite corrosion inhibitor, 0.01-0.5% of bactericide, 5-50% of solvent and the balance of LPG (Liquefied Petroleum Gas). The cleaning aerosol composition for the air conditioner, disclosed by the invention, contains the acrylic (acrylate) copolymer and the composite corrosion inhibitor, so that the cleaning performance, stability and corrosion resistance of products are remarkably improved, and the cleaning aerosol composition has good application prospects.

Description

technical field [0001] The invention relates to a cleaning agent suitable for household air conditioners, belonging to the field of daily chemical applications, in particular to a household air conditioner cleaning aerosol composition containing an acrylic acid (ester) copolymer and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, household air conditioners have become very popular. However, if used improperly, it will also cause pollution to the indoor environment. On the one hand, the human body, the room and the air conditioner form a closed circulation system indoors, which can easily cause bacteria, molds, viruses and other microorganisms to multiply and spread in this confined space. On the other hand, the frequent use of air-conditioning will also cause the spread of microorganisms in the air, making the heat sink and air outlet of the air-conditioning system the main source of pollution for respiratory in...
