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

Abstract

The invention relates to the field of aqueous coatings, and concretely relates to an aqueous strippable coating. The aqueous strippable coating comprises 40-80wt% of an aqueous polyurethane emulsion, 10-40wt% of an aqueous acrylate emulsion, 5-10wt% of a release agent, 0.5-2wt% of antirust agent, and the balance of water. The coating is sprayed on an object surface to be protected, and is naturally dried or undergoes low temperature heating drying to form a polymer material film on the protected surface, so the surface is effectively protected from scratches, brush burns and bruises in the processing or transportation process, and color change, pulverization, ageing and other defects due to sunlight irritation and other natural environment conditions, and the film can be manually stripped off when the surface protection is not needed, thereby the coating is convenient to use and has good effects; and the aqueous strippable coating can meet the protection of plastics, glass, metals and other different substrates, and has wide applicability.

Description

technical field [0001] The invention relates to the field of water-based paint, in particular to a water-based peelable paint. Background technique [0002] In the manufacturing industry, parts and some finished products often lose their surface due to dust, water droplets or oil stains during processing and transportation, and sometimes scratches or ultraviolet rays also lose their surface. Therefore, temporary protection during processing and transportation becomes very important. One of the common protection methods at present is to stick a layer of low-adhesive peelable tape on the surface, and remove the tape when no protection is needed. 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 behind a lot of residue or "ghosting" where the air bubbles are, detracting from the aesthetics of the surface. A feasible way to solve this problem ...
