Abstract

The invention relates to practical multifunctional high-efficiency environment-friendly water-based paint remover. The water-based paint remover is prepared from the following components in parts by weight: 35-45 parts of a main solvent, 2-8 parts of cosolvent, 2-11 parts of accelerant, 0.5-5 parts of a complexing agent, 2-12 parts of compound metal corrosion inhibitor, 0.5-6 parts of compound surfactant, 0-3 parts of solubilizer, 1-6 parts of a thickening agent and deionized water which is filled until the total amount is 100 parts. The water-based paint remover does not contain harmful substances including heavy metal, strong base, nitrite, chromate, phosphorus, amine, amide, does not contain organic solvents such as hydrochloric ether, phenol, acetone and the like with high toxicity andstrong volatility, has no flash point, low VOC, low odor, bio-degradability, no environmental pollution, mild property, safety for human body, high paint removing speed and complete removal, has excellent rust inhibition for various base materials, and does not damage coating surfaces.

Description

technical field [0001] The invention belongs to the technical field of paint spraying, in particular to a practical multi-functional, high-efficiency and environment-friendly water-based paint remover and its preparation method and application. Background technique [0002] During long-term use, the surface coatings of passenger and freight cars, aircraft, ships, automobiles, buildings, equipment, machinery and furniture in the railway industry are eroded by various corrosive media and damaged by mechanical damage, aging, cracking, peeling and The paint film loses its protective and decorative effect, which not only affects the appearance, but also easily induces corrosion, causing safety hazards. For the needs of safety and beauty, it is often necessary to use chemical paint removers to partially or completely remove the surface coating Remove, spray new coat of paint. [0003] The most important thing about chemical paint remover is to ensure the safety and reliability of...
