Problems solved by technology

[0003] However, domestic strippable coatings started relatively late, and are mainly oily coatings. Except for some silicone strippable coatings, other types of oily strippable coatings contain a certain amount of solvents. The volatilization during use not only wastes resources, but also It will pollute the atmosphere and bring health hazards to the personnel working in the construction environment

Abstract

The invention relates to water-based peelable paint. A manufacturing process of the water-based peelable paint comprises the following steps of A, a reaction kettle process, B, an emulsification cylinder process, C, a reaction part and D, a post processing part. Through the steps of a method, the finally made water-based peelable paint can be finally made into 100 to 120 parts by weight of crylic acid emulsion with the solid content being 40 to 45 percent. The water-based peelable paint has the innovation point that any auxiliary agents do not need to be added; a self created special polymerization process and raw materials are used for realizing the characteristics of high self inner cohesion force and low attaching force of resin, in addition, the water-resistant acid-resistant and alkali-resistant performance is excellent, certain toughness and elasticity are realized, and the self peelable performance is realized.

Description

technical field [0001] The invention belongs to the technical field of water-based paint, in particular to a water-based peelable paint. Background technique [0002] As a temporary protective coating, strippable coatings emerged in Japan, the United States and Europe in the 1970s, and are mainly used on large-scale equipment such as weapons and equipment, large machinery, and cars. Because steel, castings, glass and other materials or parts are easily polluted by water vapor, dirt and microorganisms during transportation and storage, or are subject to artificial scratches and friction, the surface of the object is damaged to varying degrees. . Affect the surface effect of the object, and even shorten the service life of the object. If a layer of temporary protective film is applied on the surface of these objects to form a dense film layer, it can effectively isolate the erosive medium, reduce the erosion rate and form anti-corrosion effect; at the same time, it can isola...
