preparation example Construction

[0055] The present invention also provides a kind of preparation method of button, comprises the following steps:

[0056] a) Spraying a primer on the surface of the semi-finished button to obtain a primer button;

[0057] b) coating the primer button to obtain a coated button;

[0058] c) Spraying a topcoat on the coated button to obtain a button;

[0059] The topcoat is the topcoat for buttons described in the above technical solution or the colored topcoat for buttons described in the above technical solution.

[0060] In the present invention, in the step a), the semi-finished button is a button blank. The present invention has no special limitation on the type of the button blank, which can be a well-known button blank in the art, such as a resin button, a natural real shell button, a plastic nylon button or an ABS button. Among them, resin buttons are artificially synthesized buttons, adding accelerators and various functional accessories (such as pearl effect, patter...

Abstract

The invention provides finishing paint for a button, colored finishing paint for the button and a preparation method of the button. The finishing paint for the button, provided by the invention, comprises 50-65% of polyester acrylic resin, 3-4.6% of a photosensitizer, 0.3-0.7% of a leveling agent, 0.1-0.3% of a defoaming agent and30-45% of a solvent. Through collocation of the various components according to a specific ratio, the fastness of a film layer of the button can be remarkably improved, the water washing resistance, the dry washing resistance and the ironing resistance of the button can be improved, and the defect that the film layer of a metal colored button easily drops off is overcome.

Description

technical field [0001] The invention relates to the technical field of buttons, in particular to a top coat for buttons, a colored top coat for buttons and a preparation method for buttons.
