Dispensing viscosity adjustable neutral potent water-soluble paint stripper

Abstract

The invention discloses a dispensing viscosity adjustable neutral potent water-soluble paint stripper, which is characterized by comprising the following raw materials based on the mass of 1 kilogram: 100 to 600 milliliters of methylene dichloride, 100 to 600 milliliters of phenol, 50 to 400 milliliters of weakly alkaline deionized water solution, 1 to 10 grams of industrial paraffin, 1 to 15 milliliters of surfactant and 1 to 50 grams of thickening agent, wherein the raw materials can be used by uniform mixing. The dispensing viscosity adjustable neutral potent water-soluble paint stripper has the technical effects that the neutral potent water-soluble paint stripper for stripping an airplane coat is particularly suitable for stripping a high-crossed solvent type epoxy or polyurethane or fluorinated polyurethane coat, and can be directly coated on the surface of a common composite materials of metal material, anodized aluminium, metal plating layer and glass fiber reinforced plastics, carbon fiber and the like for airplanes; and the paint stripping surface after using the paint stripper can be directly recoated after cleaning with a proper solvent and drying, the paint film bonding force is not affected, the repair process is simplified, and the repair cost is saved.

Description

technical field [0001] The invention relates to a strong water-soluble paint remover, in particular to a neutral strong water-soluble paint remover with adjustable formula viscosity. Background technique [0002] Aircraft are subject to long-term tests in different climates and environments around the world, and coatings are suitable protective materials for aircraft. After flying for a long time, the paint film on the surface of the aircraft is damaged, which requires regular maintenance and renovation. The paint removal of the whole machine is a big project, and after the paint removal, it is expected that the oxide film or coating of the base material will not be damaged, and it can be repainted directly after proper cleaning and drying. The bonding force of the paint film will not be affected, and the renovation efficiency will be improved. The paint stripping of aircraft is usually completed under the action of paint strippers. The paint strippers currently used are ma...

Problems solved by technology

Numerous studies have found that replacing dichloromethane with alcohol, ether, ketone, ester and other solvents can reduce environmental pollution, but the paint removal efficiency is very different, especially for epoxy or polyurethane paint films. Under certain circumstances, the stripping time of the paint can be extended from a few minutes to several hours or even days, which undoubtedly proclaims the extension of the aircraft grounding time
