preparation example Construction

[0040] The preparation method of the polyester resin extruded luminescent plate of the present invention is to separately mix the high refractive index ultrafine hollow glass microspheres, the silane coupling agent, the luminescent agent and the lubricant, mix them into the base material thermoplastic polyester resin, dry, heat the plastic melted, melt extruded, rolled and formed by cooling rolls. Specifically, the present invention comprises the following steps:

[0041] (1) Activate the glass microspheres and the silane coupling agent, stir and mix them, and then dry them. Wherein: the stirring and mixing of the glass microspheres and the silane coupling agent is as follows: first stirring at a low speed for 1 to 3 minutes, then stirring and mixing at a high speed for 4 to 8 minutes, and then drying at 120 to 160° C. for 2 to 3 hours.

[0042] (2) Stir and mix the luminescent agent and lubricant. Among them: the luminescent agent is 200-300 mesh aluminate luminescent agent...

Embodiment 1

[0047] The glass microspheres and the silane coupling agent must be activated. Stir at a low speed for 2 minutes, then stir at a high speed for 5 minutes, then add 0.5-1% of the diffusing oil agent to some raw materials, and then add 8-10% of the luminescent agent. Add them to the PET silo, stir evenly, and dry them so that the moisture content of the PET is lower than 50PPM. Put them into the extruder to heat, melt and extrude them. After cooling and shaping through the connectors, die heads, and cooling rollers, they are finally sliced ​​and inspected for storage.

[0048] Its weight ratio of raw material formula is as follows:

[0049] PET: 65-85%

[0050] Glass beads: 15-20%

[0051] Luminescent agent: 5~10%

[0052]Coupling agent: 0.5~2%

[0053] Lubricant: 0.5~2%

[0054] The ratio of glass microspheres, luminescent agent and carrier PET can be adjusted according to needs.

[0055] The process parameters of each step are as follows:

[0056] The drying temperature ...

Abstract

The invention provides a polyester resin extruding light-emitting plate and a preparation method thereof. The polyester resin extruding light-emitting plate comprises the following components in percentage by weight: 60%-90% of thermoplastic polyester resin, 3%-15% of light-emitting agents, 5%-35% of high-refractive index superfine hollow glass microspheres, 1%-5% of silane coupling agents and 0.5%-4% of octadecanamide lubricating agents, wherein the thermoplastic polyester resin is polyethylene terephthalate; and the light-emitting agents are aluminate and / or silicate light-emitting agents activated by using rare-earth. The polyester resin extruding light-emitting plate provided by the invention overcomes the defects of the prior art, is optimized in formula component and reduced in cost, is a high-brightness and long-afterglow novel environment-friendly energy-saving product, has the characteristics of excellent light absorption, light storage and self illumination, has the advantages of good physical and chemical property, flame retardancy, weather resistance, corrosion resistance, nontoxicity, harmlessness and no radiation, greatly enhances the light-emitting brightness, greatly prolongs the afterglow time, has good cost advantage, can be produced on a large scale, is energy-saving and environment-friendly and wide in application range and has excellent social and economic value.

Description

technical field [0001] The present invention relates to plastic materials and processing technology thereof, in particular to a long afterglow luminous plate extruded and formed by thermoplastic polyester activated by rare earth ions, used as a luminescent agent, and ultrafine hollow glass microspheres with high refractive index as filling materials and its preparation craft. Background technique [0002] Thermoplastic polyester has good physical and chemical properties, polyethylene terephthalate (Polyethyleneterphthalate hereinafter referred to as PET), it has excellent toughness, transparency, good weather resistance, dimensional stability, good electrical properties , easy to recycle, suitable for injection, extrusion, plastic molding. [0003] Rare earth ion-activated aluminate luminescent agent 4Sr0.7Al203: Eu (Eu is a rare earth element), which has the characteristics of light absorption, light storage, self-luminescence, environmental protection, high brightness and...
