A kind of water-based peelable coating and preparation method thereof

Abstract

The invention provides a waterborne peelable coating. The waterborne peelable coating is prepared from the raw materials of 30 to 60 of film forming material, 0 to 6 pigment, 0 to 6 of filler, 0.2 to2 of thickener, 1 to 10 of peeling agent, 0.5 to 5 of wetting agent, 0.2 to 2 of dispersant, 0.2 to 2 of leveling agent, 0.2 to 2 of defoaming agent and 10 to 20 of water. The waterborne peelable coating disclosed by the invention not only has the advantages of environmental friendliness, no toxin, no harm, higher peelable performance, stronger cohesion and excellent anti-corrosion and antifoulingproperty of a waterborne coating; furthermore, the waterborne peelable coating can effectively solve the defect that a curing speed of the waterborne coating is slow; meanwhile, the waterborne peelable coating disclosed by the invention has the advantage of easiness in repeat recycling and usage.

Description

technical field [0001] The invention relates to a paint, in particular to a recyclable, water-based peelable paint and a preparation method thereof. Background technique [0002] The research on peelable protective film began in the Second World War, and it has been produced and used on a large scale in Japan, Europe and the United States in the 1970s. This temporary protective film is coated on the surface of the protected object to form a tightly structured film layer, which can isolate the protected material from the corrosive medium of the outside world, reduce the corrosion rate, and thus play an anti-corrosion role; it itself is in the process of film formation Due to surface adsorption, viscous force and other forces, it can absorb the dirt on the surface of the protected object, thus playing the role of decontamination. [0003] In the manufacturing industry, parts and some finished products often lose their surface due to dust, water droplets or oil stains during p...

Problems solved by technology

However, for items with complex surfaces, such as curved or uneven surfaces, the tape cannot cover every place, thus leaving many air bubbles

When the tape is removed, it often leaves a lot of residue or "ghosting" where the air bubbles are located, detracting from the aesthetics of the surface
