Vehicle-carrying air-conditioning refrigerating system plugging agent

Abstract

The invention discloses a vehicle air conditioning refrigeration system leak-stopping agent which has low cost and no toxicity, is environment-friendly, can prevent refrigerant from leaking from connecting parts and pipeline sand holes, avoid the waste of the refrigerant, reduce the maintenance times of the on-board air conditioning, and decrease the maintenance cost of the vehicle. Alkyl silicone oil with 0.1 to 70 percent of the total weight, alkoxyl silicone oil with 0.5 to 70 percent of the total weight, hydroxyl-terminated silicone oil with 0.1 to 50 percent of the total weight, organicamine curing agent with 0.1 to 10 percent of the total weight, and organic tin with 0.1 to 10 percent of the total weight are taken as raw materials, and the leak-stopping agent can be produced by adding the raw materials into a dry stirring tank and evenly stirring the raw materials.

Description

Technical field: [0001] The invention relates to a plugging agent added to air-conditioning refrigerants to prevent refrigerant leakage, especially a low-cost, non-toxic and environmentally friendly agent that can prevent refrigerant from leaking from connecting parts and pipeline trachoma and avoid waste of refrigerant , Reduce vehicle air conditioner maintenance times, reduce vehicle maintenance costs of vehicle air conditioning refrigeration system plugging agent. Background technique: [0002] The on-board air-conditioning system often causes refrigerant leakage due to loose connections or sand holes in the pipeline, which affects the normal operation of the refrigeration system. To this end, the following three methods are commonly used to solve the problem, but there are different degrees of problems. [0003] 1. Add refrigerant [0004] Adding refrigerant is only an expedient measure, because the leakage problem is not fundamentally solved, the newly added refrigera...

AI Technical Summary

Problems solved by technology

[0004] Adding refrigerant is only an expedient measure, because the leakage problem is not fundamentally solved, the newly added refrigerant will still seep out, continuously adding refrigerant will not only bring operational troubles to the car owner, but also cause waste of refrigerant Phenomenon, bring certain economic loss to the owner;

[0005] 2. Replacement parts

[0006] To replace parts, the location of the leakage needs to be found first, and then the leaking parts can be replaced. There are problems of long working hours and high cost, which affects the normal operation of the vehicle and brings great economic losses to the owner.

[0007] ① Long working hours: Many leak points are difficult to detect with the naked eye, making it difficult to determine the leak location, and it takes a long time to check for leaks; it is troublesome to replace parts, especially when replacing metal parts such as evaporators. one working day;

[0008] ②High cost: The cost of air-conditioning components for mid-to-high-end cars is high, and the cost of working hours is also high.

However, the plugging agent used not only contains toxic and harmful substances such as dichloromethane, but also is only effective for rubber sealing gaskets, and is ineffective for leakage caused by trachoma on the pipeline.
