Strippable coating water dispersion material

Abstract

The strippable coating water dispersion material is characterized by that (a). containing (wt%) 5%-40% of acrylic copolymer emulsion whose glass-transition point (Tg) is greater than 40 deg.C and 60%-95% of acrylic copolymer emulsion mixture whose glass-transition point (Tg) is 5 deg.C--- -20 deg.C; (b). containing 0.5-1.0% of ethene monomer containing acid radical in the above-mentioned mixture; (c). in the above-mentioned mixed acrylic copolymer emulsion, adopting at least more than one kind of acrylic copolymer formed by using reactive surfactant to make polymerization; and (d). the grain size of acrylic copolymer emulsion is less than 100 nanometers.

Description

technical field [0001] The present invention relates to an aqueous dispersion of peelable paint for the purpose of temporary protection of articles during distribution, such as temporary storage outdoors during distribution, and effective temporary protection of articles when used for outdoor exposure. Background technique [0002] For example, automobiles, vehicles, mechanical parts, household items made of metal, other iron or non-ferrous metal products, wood products, glass products, rubber products and lacquerware (hereinafter referred to as "articles") before reaching the user's hands, There are more and more situations where it is transported from the production site and temporarily stored outdoors. [0003] In these cases, during the period (usually 2-12 months) before these items reach the user, due to, for example, dust, iron powder, salt, acrylic, acids, coal ash, dead insects Attachments such as body fluids, feces of birds, insects, etc., and sun rays, wind and r...

Problems solved by technology

[0012] However, in the aqueous dispersion of acrylic resin necessary for the above-mentioned acrylonitrile, harmful nitrogen oxides are generated when the unused coating after peeling is burned, and there is a problem of causing environmental pollution.
