Problems solved by technology

[0004] 1. The production efficiency is low. Different products must be selected for different processes. The cleaning and anti-rust processes require manual operation, which wastes a lot of labor costs.
[0005] 2. The management is inconvenient. The management of two or more products requires more manpower. If the management is not proper, the products will be mixed.
[0006] 3. Although hydrocarbon cleaning agents are environmentally friendly and safe, most products on the rust inhibitor market contain toxic and harmful ingredients such as nitrite
[0007] 4. Anti-rust oil products have flammable and explosive characteristics during use, and there are problems such as potential safety hazards
[0008] 5. Anti-rust oil products are prone to safety accidents during storage due to their low flash point
[0009] After analysis, the reason for the above problems is that there are many types of products, different products must be selected in different processes, and the quality of products in the anti-rust process is uneven, toxic, harmful, flammable and explosive

Abstract

The invention relates to the technical field of cleaning agents, particularly to an efficient anti-rust environmentally-friendly hydrocarbon cleaning agent and a preparation method thereof, wherein the efficient anti-rust environmentally-friendly hydrocarbon cleaning agent comprises, by mass, 40-50% of n-tetradecane, 30-40% of n-hexadecane, 9-29% of n-pentadecane, 0.4-0.8% of dioctylamine, and 0.2-0.6% of a RP333H hard film rust inhibitor. According to the present invention, with the efficient anti-rust environmentally-friendly hydrocarbon cleaning agent and the preparation method thereof, theanti-rust performance is increased under the premise of the ensuring of the original performances of the hydrocarbon cleaning agent so as to substantially improve the working efficiency of the production enterprise, the problems of cleaning and rust prevention can be simultaneously solved with the same product, and the difficult problem that different processes must adopt different products is solved.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to an efficient anti-rust environmental protection hydrocarbon cleaning agent and a preparation method thereof. Background technique [0002] With the rapid development of the machinery manufacturing industry, the country and some environmental protection departments are paying more and more attention to environmental protection. All walks of life have put forward more environmental protection requirements for the cleaning industry, which is a challenge for the cleaning industry and cleaning manufacturing enterprises. A huge challenge, especially in the machinery manufacturing industry. At present, most machinery manufacturing industries use solvent-based hydrocarbon cleaning agents for cleaning operations, because solvent-based hydrocarbon cleaning agents have great advantages compared with traditional water-based cleaning agents. The advantage is that it is very safe for t...
