Indoor temporary protection water-based strippable coating and preparation method thereof

The invention relates to an indoor temporary protection water-based strippable coating and a preparation method thereof, the coating is composed of a base resin, a color paste and an auxiliary agent A. The base resin is a mixture of a water-based polyurethane emulsion and a water-based acrylic emulsion according to a ratio of 1: 0.7-1; the color paste is prepared from a hydroxyethyl cellulose solution, a filler, a pigment, an auxiliary agent and a solvent. The indoor temporary protection water-based strippable coating provided by the invention adopts a brush coating or dip coating construction mode, and has the advantages of low VOC (volatile organic compound) emission, environment friendliness, convenience in construction, easiness in stripping, high drying speed, good compactness, balanced adhesive force and strippability and the like. After being coated on the surface of the precise instrument equipment, the coating can be quickly dried to form a film at room temperature to temporarily protect the precise
