AI Technical Summary

Technical Problem

Existing technologies in HVAC and refrigeration systems suffer from problems such as high frictional loss, reduced heat exchange efficiency, refrigerant corrosion, and oil carbon deposition. Traditional refrigeration oil additives have poor durability, are complex to apply, and are costly. Nano-coating technology is also complex to apply and lacks widespread applicability.

Method used

The cold coating uses a mixture of A and B agents. Agent A consists of chlorinated paraffin and aryl base oil, while agent B consists of aryl base oil and epoxidized soybean oil. By mixing them on the metal surface, a nanoscale protective film is formed, providing synergistic protection and boundary lubrication, reducing friction and improving heat exchange efficiency.

Benefits of technology

It achieves a comprehensive effect of long-term friction reduction, corrosion prevention, and efficiency improvement, reducing the friction coefficient by more than 35%, increasing heat exchange efficiency by 15-25%, saving energy by 15-20%, extending equipment service life, and is easy to construct and compatible with commonly used refrigerants.

Abstract

This invention relates to the field of cold coating technology, and in particular discloses a dual-agent mixed cold coating and its preparation method and application, consisting of agent A and agent B. Agent A consists of the following components: chlorinated paraffin 89-91 wt% and aryl base oil 9-11 wt%; agent B consists of the following components: aryl base oil 65.5-69.5 wt% and epoxidized soybean oil 30.5-34.5 wt%; the mass mixing ratio of agent A to agent B is 8:2. The beneficial effects are as follows: The cold coating of this invention, composed of a dual-agent mixture of A and B, provides synergistic protection with agent A and boundary lubrication with agent B. The combined effect of the two, after use, through a polar molecular adsorption mechanism, forms a nanoscale protective film based on short-chain paraffin on the metal surface inside the refrigeration and heating system. This significantly reduces the coefficient of friction, improves heat exchange efficiency, and blocks refrigerant corrosion, achieving high energy efficiency and energy saving of 15-20%. It is chemically stable and remains effective for a long time unless subjected to strong acid or alkali corrosion, far exceeding the 3-6 month lifespan of traditional additives, extending equipment lifespan and reducing maintenance costs.
