Abstract

The invention discloses a detergent for a tank truck. The detergent is prepared from the following components in percentage by weight: 17-20 percent of sodium alkyl benzene sulfonate, 2-3 percent of lipophilic emulsifier, 0.5-1.5 percent of a detergent assistant, 6-8 percent of a corrosion inhibitor and the balance of water. The invention also discloses a preparation method of the detergent for the tank truck. The detergent for the tank truck is strong in greasy dirt removing capability and is good in cleaning and corrosion inhibition efficiencies.

Description

Technical field [0001] The invention relates to an oil tank car detergent, and the invention also relates to a preparation method of the oil tank car detergent. Background technique [0002] A large number of train tank cars and automobile tank cars are used to store and transport various oil products in the refinery every day, and they often need to be cleaned. Existing oil (product) tank car detergents are often expensive, do not contain lipophilic emulsifiers, detergency and corrosion inhibition rate are not high enough, cleaning efficiency is low, and the surface of the train tank car and automobile tank car after cleaning is easy to form Rust film. Summary of the invention [0003] One of the objectives of the present invention is to provide a cleaning agent for tank trucks with low cost, strong degreasing ability and good corrosion inhibition effect. [0004] The second object of the present invention is to provide a preparation method of the above-mentioned oil tank truck d...
