Efficient paint remover and preparation process thereof

Abstract

The invention discloses a novel powerful paint remover capable of removing paint on surfaces of oilfield oil pipelines and paint on surfaces of other equipment efficiently. The preparation process comprises the steps of: taking dichloromethane, benzyl alcohol, ethyl acetate, ethylene glycol monobutyl ether, paraffin, ethanol, lactic acid, formic acid, urotropine, JFC and OP-10 according to weight parts; stirring the JFC, the OP-10, the benzyl alcohol, the ethyl acetate, the ethylene glycol monobutyl ether, the paraffin, the ethanol, the lactic acid, the formic acid and the urotropine in a reaction kettle at a temperature of 45-50 DEG C for 1.5-2 hours until the paraffin is completely dissolved; adding the dichloromethane and stirring for 20-30 min; and stirring uniformly in the reaction kettle to obtain the paint remover. The invention provides a paint remover which can efficiently remove old and shabby paint films on surfaces of various mechanical equipment and paint on surfaces of mechanical equipment, such as paint on metal surfaces of airplanes, paint on surfaces of train wheels and the like, brings convenience for fault detection and recoating on metal materials, has no damage to metal and wood surfaces, and has excellent paint removal performance.

Description

technical field [0001] The invention is a novel powerful paint remover which can effectively remove the paint on the surface of oil pipelines in oil fields and other various equipment. Background technique [0002] To maintain a long service life in various harsh environments in the wild, the most effective anti-corrosion method is to paint the surface with anti-corrosion paint. In Jiangsu Oilfield Trial Production Plant No. 3, each oil production team has a large number of oil delivery and water injection pipelines in the field, which must maintain a long service life in various harsh environments in the field, and the most effective anti-corrosion method is to paint on the surface Anti-corrosion paint. In the past ten years, anti-corrosion paint has to be painted every two years, causing the paint film to be too thick, which affects the safety and appearance of the pipeline. The manual mechanical method of paint removal is used in each team, and the old paint is removed m...
