Abstract

The invention relates to the field of chemical powder coating, in particular to a bend-resistance powder coating. The invention aims to provide bend-resistance powder coating which can ensure powder coating films that are more than 60 micrometers thick on workpieces do not crack when the powder coating is sprayed on box bodies, the workpieces or various antitheft doors and the box bodies, the workpieces or the various antitheft doors are punched at 90 to 180 DEG, in order to overcome the low bend resistance drawback of the conventional powder coating. The technical scheme adopted by the invention is implemented as follows: the components of the bend-resistance powder coating include carboxyl resin, triglycidyl isocyanurate (TGIC), BaSO4(filler), delustering agent 803A, curing agent 32-18A and pigment, wherein the acid value of the carboxyl resin is 20 to 40 micrograms of KOH per gram, and the pigment is one or more of titanium white, ferrite yellow, iron oxide red and dry-ground black limestone powder.

Description

A bending-resistant powder coating technical field The invention relates to the field of chemical powder coatings, in particular to a bending-resistant powder coating used for various boxes, workpieces and various anti-theft doors made of metal plates that need to be sprayed and then stamped or bent 90°-180°. . Background technique Powder coatings are widely used in the coating of various cabinets, workpieces and surfaces of various security doors, especially for the coating of various cabinets, workpieces and surfaces of various security doors made of metal sheets. Existing powder coatings that are used for spraying are not bending-resistant powder coatings, and it is only used for the coating of casings, workpieces and various security door surfaces that are no longer stamped or bent after spraying. In use, the existing powder coatings have a problem that when the boxes, workpieces and various security doors made of metal sheets need to be sprayed and then stamped at 90...
