Abstract

The invention relates to the technical field of water-based coatings, in particular to a peelable temporary protection water-based coating, which comprises the following components in parts by weight: 5-8 parts of water, 50-60 parts of a water-based polyurethane emulsion, 30-40 parts of a water-based acrylic emulsion, 0.5-1 part of a defoaming agent, 0.3-0.5 part of a flatting agent, 2-4 parts of a tackifier, 4-5 parts of slow drying water and 0.1-0.5 part of a pH regulator. The problem that a temporary protective coating in the prior art cannot completely adapt to temporary protection of surfaces in various shapes is solved. The peelable temporary protection water-based paint is low in adhesion force of a formed film on the surface of a material, easy to peel and free of residues, and has the characteristics of high tensile strength, water resistance, alcohol resistance, acid and alkali resistance and the like, so that the peelable temporary protection water-based paint can be suitable for temporary protection of the surfaces of materials such as plastic, metal and glass.

Description

technical field [0001] The invention relates to the technical field of water-based paint and its preparation method, in particular to a strippable temporary protective water-based paint and its preparation method. Background technique [0002] In the prior art, temporary protective coatings are generally used in the textile printing industry, electroplating industry, automobile industry, home cleaning, mobile phone cover industry, and membrane switch industry. [0003] Textile printing industry: Under the traditional printing process, it is necessary to first attach the platen paper to the surface of the printing platen and then brush the water-based platen glue (positioning effect) to dry and then start printing. It is easy to have glue during the removal process of the subsequent platen paper The glue residue on the paper needs to be removed by scrubbing with an organic solvent. [0004] Electroplating industry: In the process requirements of partial electroplating, stick...
