preparation example Construction

[0026] Based on the inventive concept of the long afterglow weather-resistant luminous nylon plastic composed of the above weight parts, the present invention also discloses a preparation method of a long-lasting weather-resistant luminous nylon plastic. The method includes the following steps:

[0027] 1) The coupling agent and the rare earth aluminate are weighed in proportion and uniformly mixed to prepare the first mixture;

[0028] 2) After weighing the transparent nylon, some fillers, photoaging aids, antioxidants and lubricants in proportion, they are evenly mixed with the first mixture to prepare the second mixture;

[0029] 3) Add the second mixture to the main feeding port of the twin-screw extruder, then add the remaining proportion of fillers from the side feeding port of the twin-screw extruder, and melt and blend it at an extrusion temperature of 210-260°C Extruding and granulating to prepare long afterglow and weather-resistant luminous nylon plastic.

Embodiment 1

[0032] The long-lasting weather-resistant luminous nylon plastic is prepared by the above-mentioned disclosed preparation method, and no filler is added during the implementation process. The weight part of product 1 is composed of: transparent nylon, 92.5 parts by weight; 6 parts by weight of rare earth aluminate; Isopropyl titanate TTS, 0.5 parts by weight; Ultraviolet light absorber UV-234, 0.2 parts by weight; Stabilizer UV-944, 0.3 parts by weight; Antioxidant 1098, 0.1 parts by weight; Antioxidant 168, 0.1 parts by weight ; Lubricant TAF, 0.3 parts by weight.

Embodiment 2

[0034] The above-mentioned disclosed preparation method is used to prepare long-lasting weather-resistant luminous nylon plastic, and the filler is selected from alkali-free chopped glass fiber. The parts by weight of product 2 are: transparent nylon, 72.2 parts by weight; alkali-free chopped glass fiber, 15 parts by weight; Rare earth aluminate, 10 parts by weight; Isopropyl triisostearyl titanate TTS, 1 part by weight; Ultraviolet light absorber UV-234, 0.4 parts by weight; Stabilizer UV-944, 0.6 parts by weight; Antioxidant 1098, 0.15 parts by weight; antioxidant 168, 0.15 parts by weight lubricant TAF, 0.5 parts by weight.

Abstract

The invention provides a long-afterglow weather-proof noctilucent nylon plastic and a preparation method thereof, and relates to the technical field of high polymer materials. The long-afterglow weather-proof noctilucent nylon plastic is prepared from, by weight, 70 to 93 parts of transparent nylon, 0 to 15 parts of a filler, 5 to 10 parts of rare earth aluminate, 0.5 to 1 part of a coupling agent, 0.5 to 1 part of a light aging aid, 0.2 to 0.3 part of an antioxidant and 0.3 to 0.5 part of a lubricant. According to the noctilucent nylon plastic prepared by the invention, the transparent nylon is used as a base material, alkali-free chopped glass fibers and / or glass beads are selected as reinforcing substances for filler, rare earth aluminate is used as noctilucent powder, and based on the characteristics of high transparency, good mechanical property, good chemical resistance and good processability of the transparent nylon, the reinforcing substances and a light aging aid are properly filled, so that the noctilucent plastic has the characteristics of high luminance and long afterglow duration, and also has certain mechanical strength, machinability and weather resistance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a long afterglow weather-resistant luminous nylon plastic and a preparation method thereof. Background technique [0002] Luminous plastic is a material that combines luminous powder with other plastics. The material can be stimulated to accumulate energy by being irradiated by an external light source, and the material can release energy to emit light in a dark environment. With the improvement of people's living standards, the requirements for daily products are not only functional, but people have more pursuits in aesthetics. Products with various luminous effects are gradually increasing, such as luminous fabrics, luminous interior and exterior decorations, luminous signage, etc. At present, the luminous plastics with long afterglow are mainly based on thermosetting epoxy resin or general-purpose thermoplastics, and rare earth aluminate is luminous powder.
