Embodiment 1

[0037]

[0038] Wherein, the weight ratio of silicone resin and polyketone resin in the reflective aid is 3:7;

[0039] The raw materials are weighed according to the above weight parts, pre-mixed for 10 minutes, melted and extruded at a temperature of 115°C, cooled and crushed into a powder with an average particle size of about 36um. Spray the powder evenly on the LED lampshade with an electrostatic spray gun, send the sprayed lampshade into the oven, bake at a temperature of about 200°C for 10 minutes, and take out the lampshade to cool naturally.

Embodiment 2

[0043]

[0044] Wherein, the weight ratio of silicone resin and polyketone resin in the reflective aid is 4:6;

[0045] The raw materials are weighed according to the above weight parts, pre-mixed for 6 minutes, melted and extruded at a temperature of 120°C, cooled and crushed into a powder with an average particle size of about 35um. Spray the powder evenly on the LED lampshade with an electrostatic spray gun, send the sprayed lampshade into the oven, bake at a temperature of about 200°C for 10 minutes, and take out the lampshade to cool naturally.

Embodiment 3

[0049]

[0050] Wherein, the weight ratio of silicone resin and polyketone resin in the reflective aid is 5:5;

[0051] The raw materials are weighed according to the above weight parts, pre-mixed for 10 minutes, melted and extruded at a temperature of 125°C, cooled and crushed into a powder with an average particle size of about 32um. Spray the powder evenly on the LED lampshade with an electrostatic spray gun, send the sprayed lampshade into the oven, bake at a temperature of about 200°C for 10 minutes, and take out the lampshade to cool naturally.

Abstract

The invention discloses a high-reflection powder coating suitable for LED lampshades and a preparation method thereof, wherein the high-reflection powder coating includes polyester resin, a curing agent, a leveling aid, pigments and fillers, and a reflection aid; wherein the reflection aid The agent is composed of silicone polymer and organic ketone polymer. In the present invention, the composition of the organic silicon polymer and the organic ketone polymer is used as a reflective aid, added to the polyester resin, and under the joint action of the curing agent, the leveling aid and the pigment and filler, the high reflective powder coating obtained When sprayed on an iron or aluminum LED lampshade, the cured coating can increase the brightness of the LED lamp by about 40% compared with the coating formed by ordinary powder coating, which is helpful for energy saving and consumption reduction.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-reflection powder coating suitable for LED lampshades and a preparation method thereof. Background technique [0002] Powder coating is an environmentally friendly coating with zero VOC emissions, which has been widely used in various metal surface coatings including LED lampshades. When the current powder coating is sprayed on the surface of the LED lampshade made of iron or aluminum, the luminous flux of the LED lamp is low, and a relatively high-power LED lamp is required to achieve the required brightness. Under the background that the country vigorously advocates energy conservation, consumption reduction and efficiency enhancement, powder coating products that can achieve energy saving (for example, LED lampshades coated with ordinary powder coatings, lamps that need to be installed with 60W, and high-reflective powder coatings after coating, You only need to insta...
