The corrosion inhibitor is to prevent the substrate from being corroded. By adopting the environment-friendly nontoxic water-based paint remover provided by the embodiment of the invention, in the paint removing process, the environment-friendly nontoxic water-based paint remover is decomposed to generate a small amount of gaseous nitrogen oxide, carbon dioxide or low molecular C, H compound and water, and does not generate substances polluting the environment.
Description
Technical Field
The invention belongs to the technical field of chemical solvents, and particularly relates to an environment-friendly and non-toxic water-based paint remover and a preparation method thereof.
Background
The paint remover is a liquid prepared by compounding aromatic compound and high-dissolving-power solvent, has strong paint film dissolving capacity, high paint removing speed, high efficiency and wide range of removable coatings, and is suitable for various paints such as alkyd, nitro, polyurea-formaldehyde rubber type ethylene, epoxy, polyester, polyurethane and the like, exterior wall coatings, powder spraying, coating removal and strong paint removing capacity.
In life, under the action of environment and physical machinery, the coating often has partial or large-area failure along with the prolonging of the service time, such as light loss, chalking, falling off, cracks, scratches, substrate corrosion and the like, or defects such as orange peel, cracks, chalking and the like appear in the preparation process of the coating, so that unqualified products appear, and the coating is required to be thoroughly removed and sprayed again. Mechanical removal of coatings has the disadvantages of time consuming, low efficiency, etc., and often cannot be achieved for parts with complex shapes. In addition, damage such as scratching of the substrate can be caused, and the removal of the coating on the surface of the substrate by using the paint remover is an effective method.
The existing paint remover can damage human skin and pollute the environment in the using process.
