Abstract

The invention discloses a white acrylic resin plastic cement primer and its preparation method. The white acrylic resin plastic cement primer provided by the invention contains main components of polystyrene modified methyl methacrylate, polymethyl methacrylate, a cellulose nitrate liquid of 80-200 second and titanium dioxide, and simultaneously contains a solvent and an auxiliary agent. The white primer prepared by the formula accords with the requirement on halogen-free paints in the mobile-phone industry. A diluent and an ultraviolet curing top finish are sprayed on polycarbonate plastic housing and buttons of a handset. The dried and cured coating has excellent boiling resistance. After boiled in water of 100 DEG C for 30 minutes, the coating will not foam, crack and change color.

Description

technical field [0001] The invention relates to the field of paint making, in particular to a white acrylic resin plastic primer used for surface coating of polycarbonate plastic shells and keys of mobile phones and a preparation method thereof. Background technique [0002] At present, the plastic casings and buttons of mobile phones are painted with halogen-containing white primers and UV radiation-curable topcoats, and also with halogen-free white primers with UV radiation-curable topcoats. The limitation of environmental management substances has clearly stipulated the halogen content in the mobile phone coating formula. It is required that the bromine content in the mobile phone coating formula is less than 900ppm, the chlorine content is less than 900 ppm, and the total content of bromine and chlorine is less than 1500 ppm. The primer is not suitable for some mobile phone manufacturers; at present, some mobile phone paint users require the white primer cover to be spra...
