Abstract

The invention discloses a method for manufacturing a paint for temporary protection on the metal surface, which comprises the following steps: dissolving 30%-40% chloroacetic resin powder with alcohol solvent; dissolving 20% cellulose acetate butyrate with butyl acetate and dimethylbenzene mixed solvent; mixing dissolved chloroacetic resin and cellulose acetate butyrate according to 2:1-3:1; adding 0.5% dimethyl silicon oil; mixing homogeneously; adding deflocculating agent (butyl alcohol:butyl acetate=1:1). The invention is provided with adhesive force and striping property, which avoids the chemical corrosion of the metal.

Description

technical field [0001] The invention relates to a method for manufacturing a paint for temporary protection of metal surfaces. Background technique [0002] When decorating metal surfaces, temporarily protect parts, and restore the original appearance after the rest of the decoration is completed. In the past, hot-melt peelable coatings were used, which was inconvenient to use. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned deficiency, a kind of metal surface temporary protective paint manufacturing method is provided. [0004] The technical solution of the present invention is: a method for manufacturing a paint for temporary protection of metal surfaces, characterized in that: the main components include 80%-85% vinyl acetate resin, 15%-20% cellulose acetate butyrate and a small amount of di Methyl silicone oil is sprayed on the metal surface. After the solvent volatilizes, a layer of peelable protective film can b...
