Problems solved by technology

On the other hand, from a technical point of view, simply using the above-mentioned mixed wax as an additive to improve the anti-scratch effect is also quite limited, so it is expected to provide high surface hardness and decorative performance, good surface scratch resistance, economy or its coating. Powder coatings where surface modifiers are commercially available are extremely desirable

example 1

[0099] 100 parts by weight of epoxy resin (E-12), 100 parts by weight of polyester resin SYP4500 (Huangshan Yongjia Sanli product, AV about 75mgKOH / g), 3 parts by weight of leveling agent Resiflow P67 (Estron), 78.1 parts by weight of BaSO 4 Filler, 1.5 parts by weight of benzoin, 15 parts by weight of FR921-1 (high molecular weight PVDF, particle size about 50 μm, Shanghai Sanaifu Company) and 2.4 parts by weight of carbon black were placed in a plastic bag and mixed manually for 3-5 minutes. Then add it into a twin-screw test extruder to melt and homogenize, tablet, cool and grind into fine powder, and sieve through 180 mesh. Electrostatic spraying on degreased cold-rolled steel plate, curing at 180°C / 15 minutes. Then test according to the above test method, the specific results are listed in Table 1.

example 2-10 and comparative example 11

[0101] Repeat Example 1, but use different fluorocarbon resins or their combinations and the combination of characteristic wear-resistant inorganic fillers to replace the same components in Example 1; as Comparative Example 11, completely use 93.1 parts by weight of BaSO 4 The various additive groups in Substitution Example 1 were compared with each other, and the specific results are also listed in Table 1.

example 12

[0103] 186 parts by weight of polyester resin CC2440-2 (Cytec, AV about 34mgKOH / g), 14 parts by weight of TGIC, 3 parts by weight of leveling agent Resiflow P67 (Estron), 78.1 parts by weight of BaSO 4Filler, 1.5 parts by weight of benzoin, 15 parts by weight of FR921-1 (high molecular weight PVDF, particle size about 50 μm, Shanghai Sanaifu Company) and 2.4 parts by weight of carbon black were placed in a plastic bag and mixed manually for 3-5 minutes. Then add a twin-screw test extruder to melt and homogenize, tablet, cool and grind into fine powder, and sieve through 180 mesh. Electrostatic spraying on degreased cold-rolled steel plate, curing at 200°C / 10 minutes. Then test according to the above test method, and the specific results are listed in Table 2.

Abstract

The invention discloses powder paint with high surface harness and decoration. The powder paint contains one or more 100% fluorocarbon resin by weight, one or more glass microspheres and ceramic microballons as well as a characteristic inorganic filler taking nephelinite as a main component. Compared with the prior art, the fluorocarbon resin of the invention has good compatibility with a film-forming resin, and the coating embodies excellent decorative effect.

Description

technical field [0001] This invention relates to powder coating compositions. More precisely, the present invention relates to a powder coating composition having high surface hardness and decorative properties, using a special 100% content of fluorocarbon resin, a characteristic wear-resistant inorganic filler or a combination thereof as a coating surface hardening material; Furthermore, the present invention is also related to the application of this special fluorocarbon resin and the powder coating composition formed therefrom. Background technique [0002] Thermosetting powder coating is an environmentally friendly coating with no or very little solvent and volatile emissions, especially in today's increasingly stringent VOC (Volatile Organic Compounds, volatile organic compounds) emission standards, it is of great significance and market share is increasing year by year. [0003] Thermosetting powder coatings are mainly composed of functional film-forming resin materi...
