Embodiment 1

[0011] Embodiment 1, (ingredients are by weight)

[0012] The manufacturing formula is 60 parts of polyester resin CC450 (Shanghai Cytek Company), 5 parts of TGIC (PT710 of Ciba Company), 0.4 part of benzoin, 1 part of PV88 leveling agent (Dexinli Company), 35 parts of precipitated barium sulfate, and short glass fiber (3mm) 20 parts, 2 parts of 311 carbon black. The short glass fibers are crushed at high speed, and then mixed with polyester resin, TGIC, benzoin, PV88, precipitated barium sulfate, and carbon black for 5 minutes. Then extrusion, tableting, crushing, milling.

[0013] The above-mentioned powder coating is made into a coating film with a thickness of 60-80 μm. The mechanical properties tested are: impact strength ≥ 120kg.cm, bending φ2mm, pencil hardness ≥ 3H, adhesion (cross-cut) grade 0.

Embodiment 2

[0014] Embodiment 2, (ingredients are by weight)

[0015] The manufacturing formula is 30 parts of polyester resin (Shenjian 4#), 30 parts of E-12 epoxy resin (Ningbo Nanhai), 0.4 parts of benzoin, 1 part of GLP588 leveling agent (Ningbo Nanhai), 35 parts of precipitated barium sulfate, glass 15 parts of short fiber (3mm), 6 parts of R-902 titanium dioxide, 1 part of phthalocyanine green G. The short glass fibers are crushed at high speed, and then mixed with polyester resin, epoxy resin, benzoin, leveling agent, precipitated barium sulfate, and various pigments for 5 minutes. Then extrusion, tableting, crushing, milling.

[0016] The above-mentioned powder coating is made into a coating film with a thickness of 60-80 μm. The mechanical properties tested are: impact strength ≥ 120kg.cm, bending φ2mm, pencil hardness ≥ 3H, adhesion (cross-cut) grade 0.

Embodiment 3

[0017] Embodiment 3, (ingredients are by weight)

[0018] The manufacturing formula is 60 parts of E-12 epoxy resin, 5 parts of dicyandiamide, 0.4 part of benzoin, 1 part of PV88 leveling agent, 36 parts of precipitated barium sulfate, 18 parts of short glass fiber (3mm), 2 parts of phthalocyanine blue pigment . The short glass fibers are crushed at high speed, and then mixed with epoxy resin, dicyandiamide, benzoin, leveling agent, precipitated barium sulfate, and pigment for 5 minutes. Then extrusion, tableting, crushing, milling.

[0019] The above-mentioned powder coating is made into a coating film with a thickness of 60-80 μm. The mechanical properties tested are: impact strength ≥ 120kg.cm, bending φ2mm, pencil hardness ≥ 3H, adhesion (cross-cut) grade 0.

Abstract

The invention relates to a novel powder coating and a preparation method of the novel powder coating, belonging to the architectural coating field. Fiber glass is added into the formula of common powder coating to improve physical and mechanical property o the coating. The preparation method is that the glass fiber is crushed in high speed, and then is mixed, extruded, crushed and milled with the other raw materials for making the powder coating, then the powder coating is prepared.

Description

technical field [0001] The invention relates to a novel powder coating and a preparation method thereof, belonging to the technical field of powder coatings. Background technique [0002] Powder coating has the advantages of economy, environmental protection, high efficiency and energy saving, and it has developed rapidly in the world in the past two decades. With the continuous development of powder coating technology, its application fields are also expanding. Many special environments require coatings to have super strong physical and mechanical properties, such as impact strength, coating film hardness, bending properties, etc. The existing technology usually uses methods such as adding functional additives or a single filler to improve a certain performance, but the result is often that the effect is not significant, or one performance is improved while the other performance is reduced. Performance cannot be compromised. [0003] Glass fiber is made by melting glass ...
