A kind of high-efficiency paint remover and its preparation process

Abstract

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. The present invention takes dichloromethane, benzyl alcohol, ethyl acetate, ethylene glycol monobutyl ether, paraffin, ethanol, lactic acid, formic acid, urotropine, JFC, OP‑10 in parts by weight, and JFC, OP‑10 benzene Methanol, ethyl acetate, ethylene glycol monobutyl ether, paraffin, ethanol, lactic acid, formic acid, and urotropine were stirred in a 45-50°C reactor for 1.5-2 hours until the paraffin was completely dissolved, then added dichloromethane and stirred for 20- 30 minutes; stir evenly in the reaction kettle. The invention provides a paint that can effectively remove the worn-out paint film on the surface of various mechanical equipment and the paint on the surface of mechanical equipment such as aircraft metal surface paint and train wheel surface, which is convenient for flaw detection and repainting of metal materials, and does not damage metal and For wood surfaces, a paint remover with excellent paint removal properties.

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...
