AI Technical Summary

Problems solved by technology

The material of the engine circulation cooling pipeline is complex, including carbon steel, copper alloy, aluminum alloy, rubber, nylon, etc. The existing cleaning agent is only designed for a few materials, which will cause corrosion to other materials
At the same time, the existing cleaning agents cannot effectively remove the rust and scale covered by the oil stains in the presence of oil stains.
Moreover, since the cleaning agent in the prior art cleans the parts of the engine, it is very inconvenient to disassemble and assemble the parts before and after cleaning.

Embodiment Construction

[0021] The present invention will be further described in detail below in combination with specific embodiments.

[0022] The inventors of the present application found that the combination of EDDHA-Na, sodium citrate and PBTC can effectively remove rust; the combination of EDDHA-Na, alkanolamide, BS-12 and triethanolamine can effectively remove oil stains and organic pollution The combination of alkanolamide, LAN-826, and BTA can effectively protect various metal materials and organic materials including carbon steel, stainless steel, copper alloy, aluminum alloy, etc. from corrosion. The inventor combined the above components together, and by reasonably setting the ratio of each component, made the cleaning agent of the present invention, which can effectively remove the pollution components such as rust, scale, oil stain and biofilm, and has certain influence on the surface material of the equipment. The protective effect does not affect the normal use of the material.

Abstract

The invention provides a cleaning agent for an engine circulating cooling system, and a preparation method and a cleaning method thereof. The cleaning agent for the engine circulating cooling system contains 50-70% of EDDHA-Na, 5-15% of sodium citrate, 3-8% of alkanolamide, 0.5-3% of LAN-826, 0.5-3% of BS-12, 5-10% of triethanolamine, 1-3% of BTA, 5-15% of PBTC and 0-20% of water by weight. The cleaning agent is low-cost, effective, easy to manage, safe to use, simple and convenient to operate, and wide in application range; the cleaning agent has remarkable effects in the aspects, such as maintaining safety of the cooling system, recovering original performance of equipment, prolonging service life of the engine and saving energy. The cleaning agent can be used for cleaning engine circulating cooling water path, and has good corrosion inhibition and corrosion prevention function.

Description

technical field [0001] The invention relates to the technical field of engine cleaning, in particular to a cleaning agent for an engine circulation cooling system, a preparation method and a cleaning method thereof. Background technique [0002] Automobile engines need anti-rust treatment for their cooling circulation system before leaving the factory, and cleaning is the basic work of anti-rust. Cleaning can remove the hidden dangers of metal corrosion (such as various greases, dust, electrolytes, hand sweat, etc. will cause metal corrosion) and remove the rust generated by some metal pipes during production or testing. If the cleaning is not thorough, it will lead to the failure of anti-rust and cause safety hazards. [0003] Existing automobile engine cleaning agent is mainly aimed at the engine parts in processing or the parts cleaning design of the engine after leaving the factory in the maintenance process, and mainly carries out derusting and dirt to carbon steel, st...
