Surface treatment method for bathroom hardware

Abstract

The invention discloses a surface treatment method for bathroom hardware. The surface treatment method for the bathroom hardware includes the following steps of (1) grinding; (2) cleaning and drying; (3) electrostatic spraying processing, specifically, the cleaned and dried bathroom hardware workpiece is put into a spraying chamber built by a high-voltage electrostatic generator, powdery paint is sprayed on the bathroom hardware workpiece through a spraying gun, and through electrostatic reaction, the powdery paint can be uniformly adsorbed to the bathroom hardware workpiece; (4) heating, drying and curing, specifically, the sprayed workpiece is put into a drier to be heated, the sprayed paint is solidified and hardened, and single-color surface spraying processing is realized; (5) pattern attaching, specifically, patterned paper printed with patterns is torn off a carrier, uniformly attached to the bathroom hardware workpiece heated, dried and cured in the step (4), and naturally dried for 1.5-3 h, and then a protective film on the patterned paper is torn off; and (6) baking and reinforcing, specifically, the bathroom hardware workpiece with the patterns attached is put into baking equipment, baked for 30-50 min at the high temperature of 120-180 DEG C, and cooled at normal temperature.

Description

technical field [0001] The invention belongs to the technical field of producing decorative effects, and in particular relates to a method for surface treatment of bathroom hardware. Background technique [0002] Existing bathroom hardware generally adopts traditional baking varnish technology for surface treatment, but traditional baking varnish technology is easy to cause damage to construction personnel, and has a certain impact on the environment, and there are problems such as easy peeling of paint on the surface, uneven paint surface, weak adhesion, paint Insufficient surface hardness is easy to scratch and other defects. At the same time, the existing bathroom hardware water transfer printing technology has defects such as insufficient pattern definition, unclear texture and easy to fall off. Contents of the invention [0003] In view of this, in order to overcome the deficiencies of the prior art, the present invention aims to propose a method for surface treatmen...
