Abstract

The invention discloses anti-fingerprint powder coating and a preparation method and application thereof. The anti-fingerprint powder coating is prepared from, by weight, 20-40 parts of composite polyester resin A, 30-50 parts of polyester resin B and 0-30 parts of other auxiliary agents. The preparation method includes: well mixing hydroxyl polyester resin and a composite material, subjecting tomelt extrusion through a double-screw extruder, cooling sheets to the normal temperature, and crushing to obtain the composite polyester resin A; adding the composite polyester resin A, the polyesterresin B and other auxiliary agents into a premixing tank, well mixing, subjecting to melt extrusion through a double-screw extruder, cooling sheets to the normal temperature, and finally crushing andgrading through a high-speed crusher to obtain powder in particle size of 33-38micron. By synergistic effects of the composite polyester resin A and the polyester resin B, a formed coating is easy toclean and remarkable in anti-fingerprint performance, automatic fingerprint clearing is realized, and the powder coating is silky and smooth to touch and especially suitable for terminal products including furniture, door and window accessories, decorative lamps, electronic communication equipment and the like and manifests high end and elegance of products.

Description

technical field

[0001] The invention belongs to the technical field of powder coatings, in particular to an anti-fingerprint powder coating and its preparation method and application. Background technique

[0002] Since the beginning of the 21st century, with the improvement of people's material living standards, the requirements for terminal consumer products have become higher and higher, and the demand for anti-fingerprint products has gradually increased. Currently, the coatings used in anti-fingerprint products are mainly liquid paints, and paints It is extremely harmful to human health and the environment. In recent years, the country has determined to control environmental pollution enterprises, and the high pressure on environmental protection has intensified. The production of paint companies has been greatly restricted, making it difficult to promote related paint products.

[0003] Powder coatings and coatings are characterized by resource and energy saving, pollu...
