Colored polyurethane paint having elastic handfeel and used for spraying and preparation method as well as application thereof

Abstract

The invention discloses a colored polyurethane paint having elastic handfeel and used for spraying and a preparation method as well as application thereof. The paint comprises the following components in parts by weight: 20-30 parts of saturated polyester resin, 10-20 parts of hydroxy acrylic resin, 10-20 parts of thermoplastic acrylic resin, 20-30 parts of butyl acetate, 0.2-1 part of levelling agent, 0.2-1 part of defoaming agent and 5-11 parts of solvent, wherein 1-27 parts of color paste can be added to the mixture; the levelling agent is acrylic ester; the defoaming agent is organosilicon; the solvent is a PMA (propylene glycol monomethyl acetate) solvent; and the color paste is the mixture of an inorganic or organic pigment, a dispersing agent, acrylic resin and the solvent. The paint can be sprayed on plastic shells of electronic and electrical products, and has the characteristics of simple spraying process, low energy consumption, low cost, relatively little pollution, better environment friendliness, better surface fineness, excellent elastic handfeel and the like.

Description

technical field [0001] The invention relates to an organic paint, in particular to a colored polyurethane elastic hand-feeling paint for one-time spraying which is used for spraying plastic casings of electronic and electrical appliances and only needs to be sprayed once. Background technique [0002] At present, various electronic or electrical products, such as digital cameras, notebook computers, mobile phones, etc., have been widely used in people's lives. The shells of such products are mostly made of plastic and plastic materials. After the shells are processed and shaped, they need to be sprayed with protective and decorative coatings on the surface. With the improvement of people's cultural living standards and appreciation levels, delicate Feel and tactile sense of increasingly high-grade products.
