Problems solved by technology

But this will inevitably complicate the processing and increase the cost
[0008] And because the energy storage luminescent material is an inorganic material, the particle size is generally large, and it is difficult to disperse well in the polypropylene matrix, resulting in poor luminous effect
At the same time, poorly dispersed inorganic materials make the mechanical properties of the composition poor, such as causing a large drop in the impact properties of the composition, thus limiting the application of luminescent plastics

Embodiment 1～4

[0058] PP (polypropylene, 2401, produced by Beijing Yanshan Petrochemical Co., Ltd.), fully vulcanized styrene-butadiene powder rubber (VP-101, produced by Beijing Research Institute of Chemical Industry, particle size 80-110nm, gel content 80%wt), antioxidant Agent 1010 (Swiss Ciba Addyl Company), antioxidant 168 (Swiss Ciba Addyl Company), calcium stearate (Beijing Changyang Farm Chemical Factory), light-storing alkaline earth aluminate (Dalian Luming Technology Group Co., Ltd. Production, brand PLO-6D, particle size range is 12 ~ 18μ) put into the low-speed mixer and stir evenly. The mixed materials were then melt blended through a twin-screw extruder. The twin-screw extruder that uses is the ZSK-40 twin-screw extruder that German WP company produces. The extrusion temperature is 160-240° C., and the screw speed is 80-450 rpm. The materials are melted and blended uniformly by a twin-screw extruder, and then extruded and granulated. The extruded pellets were dried in a co...

Embodiment 5

[0060] First put light-storing alkaline earth aluminate (same as Example 1), silicone oil (produced by Beijing No. Divide thoroughly and mix evenly. Then above-mentioned mixture is with polypropylene (with embodiment 1), fully vulcanized powder styrene-butadiene rubber (with embodiment 1), antioxidant (with embodiment 1), calcium stearate (with embodiment 1) and (with embodiment 1) and (with embodiment 1) Embodiment 1) make each component fully mix homogeneously again in the low-speed mixer. Then the above mixed material was melt-blended by twin-screw (ZSK-40, WP Company, Germany). The extrusion temperature is 160-240° C., and the screw speed is 80-450 rpm. The materials are melted and blended uniformly by a twin-screw extruder, and then extruded and granulated. The extruded pellets were dried in a constant temperature oven at 80°C for 6 hours, and then injected into a standard sample under the condition of 180-230°C to test the mechanical properties and optical properties....

Abstract

The invention provides a long persistence luminous polypropylene composition and its preparation method. Polypropylene, luminescence material of storage light and powder rubber are fused to get the luminous polypropylene composition. The luminescent material comprises metasilicate system, aluminate system, sulfide series luminescence material of storage light. The composition is used with powder rubber whose grain diameter is 50-200nm and gelatin content is 60wt%, improving the dispersion of luminescent material in the polypropylene, reducing the friction force, increasing the mechanics property and luminous power of said composition and getting the high brilliancy, high tenacity nondiscolouring luminous polypropylene composition. If the polypropylene is divided 100 portions, the luminescent material includes 1-40 portions and the powder rubber includes 1-10 portions. The invention is used to manufacture floodlighting product.

Description

technical field [0001] The present invention relates to a luminescent plastic composition, and furthermore, relates to a long afterglow luminescent polypropylene composition and a preparation method thereof. Background technique [0002] Polypropylene (PP) is a large variety of plastics with a large quantity and a wide range. It has good mechanical properties and processing properties, and has been widely used in daily necessities, transportation, machinery, electronics and electrical industries. But PP does not have the function of glowing at night. In order to make PP plastic products have night-time luminous performance, people mainly adopt two ways: one is to apply luminous paint on plastic products, paste and inlay luminous bodies, and the other is to add luminous fillers to plastics. [0003] Coating luminescent paint, pasting and inlaying luminous bodies on plastic products is actually using PP as the main body of the structure, plus a surface with luminous function....
