Abstract

The invention relates to the field of coatings. A peelable temporary protective coating comprises, by weight, 3-25 parts of water-soluble natural polymer metal salt, 5-20 parts of a water-based polymer, 2-5 parts of an inorganic dispersant, 10-20 parts of inorganic salt, 15-70 parts of pigment and filler and 0.5-2.5 parts of a wetting agent. A film can be quickly formed, the adhesion of the cotingfilm is strong, and the coting is suitable for various substrates; the coating film has high tensile strength and elongation, can be peeled off integrally, and is convenient to use; VOC is not contained, the cured coating film can be dissolved in water for reuse, no peculiar smell nor decoration garbage is generated in the use process, and the coating is environmentally friendly and free of pollution. The peelable temporary protective coating is environmentally friendly, free of pollution, convenient to use and recyclable.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a strippable temporary protective coating. Background technique [0002] The construction of paint often involves the construction of different substrate surfaces. Different colors and effects are required on the same substrate. The completed surface needs to be protected from paint pollution, and part of the surface often needs to be protected. Generally, adhesive tape or temporary protective paint is used. Tape paper is time-consuming to paste, construction efficiency is low, and plastic waste is generated, which is not environmentally friendly; traditional temporary protective paint is mostly solvent-based products, which have high VOC content and unpleasant odor during construction, so they are not suitable for indoor use. Used in decoration. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a strippable temporary protectiv...
