Problems solved by technology

[0003] The general-purpose weather-resistant plastic masterbatches circulating in the domestic market mainly reduce the photoaging degree of plastic products by adding organic light stabilizers, but organic light stabilizers are environmentally unfriendly materials, and they themselves will also age and degrade, and most of the degradation products have Toxicity, serious damage to the environment, so it is gradually restricted in the application of plastic products that have higher requirements for environmental protection; at the same time, plastic products will also lose their weather resistance function with the degradation of organic light stabilizers

Embodiment 1

[0045] Prepare the luminescent material first, according to the weight of the luminescent material components: 100 parts of aluminum oxide, 85 parts of calcium carbonate, 10 parts of boric acid, 1.8 parts of europium trioxide, and 2.1 parts of diterbium trioxide. Prepare the raw materials and fully grind the raw materials After mixing through a 500-mesh sieve, put it into an alumina crucible, cover the raw material with a layer of activated carbon with a thickness of 8-12 mm, then install a sealing cover on the crucible and compact the raw material in it, and turn the crucible upside down on the Heating and roasting in a resistance furnace. From 20°C to 200°C, the temperature rise rate is 5-8°C / min. After 200°C, the temperature rise rate is 5-10°C / min. When the temperature reaches 1400°C, keep it for 6-8 hours, and then power off the roasting furnace. After natural cooling for 20 minutes, the crucible was taken out from the roasting furnace, cooled to room temperature naturall...

Embodiment 2

[0050]Prepare the luminescent material first, according to the weight of the luminescent material components: 90 parts of aluminum oxide, 88 parts of calcium carbonate, 10 parts of boric acid, 2.2 parts of europium trioxide, and 2.1 parts of diterbium trioxide. The raw materials are prepared, and the preparation process and The same as in Example 1, the crucible was taken out from the roaster after the roaster was powered off and naturally cooled for 28 minutes, and allowed to cool naturally to room temperature.

[0051] Mix 34 parts of luminescent materials with polyethylene (80 parts of low-density polyethylene and 20 parts of linear low-density polyethylene), tris(1,2,2,6,6-pentamethylpiperidine) phosphite (GW540) 5.5 parts, compound antioxidant (4.4 parts of stearyl thiodipropionate and 5.2 parts of antioxidant DLTP), UV-328 (2-(2'-hydroxyl-3', 5'-dipentylphenyl ) 5.8 parts of benzotriazole), 2.2 parts of polyethylene wax, composite inorganic flame retardant (36 parts of a...

Embodiment 3

[0055] Prepare the luminescent material first, according to the weight of the luminescent material components: 95 parts of aluminum oxide, 85 parts of calcium carbonate, 14 parts of boric acid, 2.8 parts of europium trioxide, and 2.5 parts of diterbium trioxide. The same as in Example 1, the crucible was taken out from the roaster after the roaster was powered off and naturally cooled for 18 minutes, and allowed to cool naturally to room temperature.

[0056] Mix 38 parts of luminescent material with polyethylene (80 parts of low-density polyethylene and 20 parts of linear low-density polyethylene), tris(1,2,2,6,6-pentamethylpiperidine) phosphite (GW540) 7.8 parts, compound antioxidant (5.8 parts of antioxidant CA and 6.6 parts of antioxidant DLTP), UV-329 (2-(2'-hydroxy-5'-tert-octylphenyl)benzotriazole ) 4.8 parts, 2.4 parts of polyethylene wax, composite inorganic flame retardant (50 parts of aluminum hydroxide and 25 parts of zinc borate) were premixed for 5 minutes in an ...

Abstract

The invention belongs to the technical field of modifying and processing technology for macromolecule, and relates to a luminescent material and a preparation method and application thereof. The luminescent material includes the following components based on weight proportion: 90-100 portions of aluminium oxide, 80-95 portions of calcium carbonate, 8-20 portions of boric acid, 1.5-5 portions of europium oxide, 2-4 portions of terbium oxide. Compared with the prior art, master batches of weather-resistant energy-storage luminescent polyethylene plastic prepared from the luminescent material of the invention have excellent weather-resistant performance and durability, environment-friendly degradation products, longer luminescence time and zero radioactivity. The master batches of the luminescent material are widely used in architectural ornament, transportation, fire protection, electrocommunication, subway tunnels, advertising boards and other plastic products.

Description

technical field [0001] The invention belongs to the technical field of polymer modification and processing, and relates to a luminescent material and its preparation method and application. Background technique [0002] The existing photoluminescent plastic materials often use zinc sulfide as the main raw material. Chinese patent 92108547.8 discloses a luminescent substance composition containing phosphor. The composition is composed of zinc sulfide, copper sulfide and a certain amount of activator. This material has a strong luminous intensity, and the continuous luminous time in the dark can reach more than 12 hours. It can be widely used in safety implementation, construction, electrical appliances, public transportation, textile printing, advertising, manufacturing and other industries. However, the substance is somewhat radioactive and has low energy storage. If the material is used to make plastic products, it will have adverse effects on the environment and the hum...
