Abstract

The invention discloses an outdoor scratch-resistant powder coating. The coating is prepared from the following components in percentage by mass: 56%-60% of polyester resin, 4.2%-4.5% of a TGIC (triglycidyl isocyanurate) curing agent, 1%-1.5% of a smoothing deaerator, 1%-1.5% of a leveling agent, 0.5%-5% of silicone masterbatch and 27.5%-37.3% of pigment and filler. After the powder coating is cured, a coating film is flat and smooth without pinholes, has good leveling property, adhesive force and impact resistance, and surface hardness of the coating film is high; the prepared powder coatingcan be used in outdoor fields such as outdoor aluminum profile powder, outdoor furniture powder and the like, and has excellent scratch resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an outdoor scratch-resistant powder coating. Background technique [0002] The appearance of outdoor items such as sports equipment, outdoor building curtain walls, outdoor place guardrails, outdoor furniture, etc. are exposed to the outdoor environment for a long time, and are easily affected by the outside world and cause scratches, which in turn cause scratches on the surface of the coating film and affect the appearance of the appearance parts. At the same time, it causes the damage of the coating, which affects the protection of the coating to the substrate and reduces the service life of the substrate. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an outdoor scratch-resistant powder coating. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005...
