Abstract

The invention relates to an industrial water treatment agent for oil stain cleaning and a preparation method thereof, which is prepared by preparing the following components according to the weight ratio: pull-off powder: 10%-25%, sodium dodecylbenzenesulfonate: 6%-12% , Ethanol: 3% to 6%, isopropanol: 10% to 20%, benzotriazole: 0.7% to 1.2%, rotropine: 1% to 2%, and the balance is deionized water. The preparation method comprises the following steps: 1) putting ethanol and isopropanol into a reaction kettle, stirring evenly and raising the temperature to 30°C-60°C; 2) adding pull-off powder into the kettle and stirring until dissolved; 3) adding Add sodium dodecylbenzenesulfonate and stir until dissolved; 4) Add deionized water into the kettle and stir well; 5) Add benzotriazole into the kettle and stir evenly; 6) Add urethane into the kettle Tropin, stir evenly; 7) discharge, measure and pack after cooling to normal temperature. The invention has the advantages of thorough scale dissolution, strong penetration, fast scale removal speed, no need to stop the car during cleaning, and can complete cleaning and corrosion inhibition at one time.

Description

technical field [0001] The invention relates to an industrial water treatment agent for oily dirt cleaning and a preparation method thereof, which belongs to the compounding technology of industrial water treatment agent for oily dirt cleaning. Background technique [0002] At present, most of the oil stain cleaning industrial water treatment agents produced in my country are acid cleaning agents. During cleaning, the PH value of the system is low, the equipment is easy to corrode, and the oil dirt on the equipment cannot be removed deeply, and it needs to be stopped for cleaning. The cleaning time is long and the cost is high, which affects production. Therefore press for a new type of cleaning agent that dissolves scale completely, has strong penetrating power, is fast in descaling speed, does not need to stop when cleaning, and can clean and inhibit corrosion once. Contents of the invention [0003] The present invention aims to solve the above-mentioned technical prob...
