Embodiment 1

[0050] like Figure 1-3 As shown, a kind of mechanoluminescence guardrail net, comprises metal net 6, long afterglow electroluminescence material, and described long afterglow electroluminescence material is covered on the surface of metal net 6; Described metal net 6 is grid shape; The long afterglow electroluminescent material uses strontium aluminate as the host material, Eu 2+ 、Dy 3+ electron doping.

[0051] The metal mesh 6 is barbed wire; electron-doped Eu 2+ 、Dy 3+ The final strontium aluminate is used as a long-lasting electroluminescent material, which is in powder form; the long-lasting electroluminescent material is waterproofed with pyrophosphoric acid; The material is added to pyrophosphoric acid, and the mass ratio of the luminescent material to pyrophosphoric acid is (0.8-1.2):(1.10-1.40); the luminescent material modified by superpyrophosphoric acid is in powder form.

[0052] The specific surface area S of the powdery luminescent material is 400-780m 2 ...

Embodiment 2

[0058] The present invention also provides a preparation process of the mechanoluminescence fence net, the preparation process comprises steps:

[0059] S1. Preparation of Eu by high temperature reduction 2+ 、Dy 3+ doped strontium aluminate;

[0060] S2. Modifying strontium aluminate long-lasting electroluminescent material with pyrophosphoric acid, so that it not only has luminous performance, but also has water resistance;

[0061] S3. Perform dipping treatment on the surface of the metal mesh 6, and then uniformly disperse the water-resistant modified long-lasting mechanoluminescent material on the surface of the metal mesh 6 to obtain a mechanoluminescent fence net.

[0062] In the step S1, materials for preparing strontium aluminate include: aluminum nitrate, strontium nitrate, europium oxide, and dysprosium oxide.

[0063] In the step S1, the reducing gas used for preparing strontium aluminate is hydrogen, and the protective gas is nitrogen.

[0064] In the step S2, ...

Embodiment 3

[0077] In the step S2, the strontium aluminate long-lasting electroluminescence material, pyrophosphoric acid, and dimethylformamide are dispersed in dimethylformamide at a mass ratio of 0.8:1.10:450, and after ultrasonic dispersion for 15 minutes, the Stir vigorously in the pot at 60 degrees Celsius for 10 hours to obtain a pyrophosphate-modified strontium aluminate long-lasting electroluminescent material, which improves its anti-hydrolysis performance and prolongs its service life.

[0078] In the step S3, a powder dipping method is used in the dipping treatment.

[0079] The pyrophosphoric acid-modified strontium aluminate long afterglow electroluminescent material was repeatedly washed twice with dimethylformamide and tetrahydrofuran, and then dried at 100 degrees Celsius to obtain the pyrophosphate-modified water-resistant strontium aluminate long afterglow Mechanoluminescent materials.

[0080] In the step S3, the water-resistant strontium aluminate long-lasting electr...

Abstract

The invention discloses a mechanoluminescence guardrail net and a preparation process thereof. The preparation process comprises the following steps of preparing an Eu < 2 + > and Dy < 3 + > doped strontium aluminate long-afterglow mechanoluminescence material through high-temperature reduction; using pyrophosphoric acid for modifying the strontium aluminate long-afterglow mechanoluminescent material to enable the strontium aluminate long-afterglow mechanoluminescent material to have water resistance; carrying out plastic dipping treatment on the surface of the guardrail net by using a powderplastic dipping method, and uniformly dispersing the water-resistant strontium aluminate long-afterglow luminescent material carried by the guardrail net onto the surface of the guardrail net; carrying out practical application test. The mechanoluminescent material is doped in the plastic dipping process of the guardrail net, the lightness of the material on the surface of the guardrail net is improved, meanwhile, the guardrail net has the characteristic of long afterglow mechanoluminescence and has the luminescent function at night, and light becomes stronger during the process of climbing over, colliding and even artificially damaging the guardrail at night. A monitoring system is additionally arranged, so that the real-time on-line monitoring is conducted on the railway environment, andthe automatic recognition and alarming are conducted on the guardrail damage and abnormal conditions.

Description

technical field [0001] The invention relates to the technical field of guardrail nets, in particular to a mechanoluminescent guardrail net and a preparation process thereof. Background technique [0002] The fence net is installed on both sides of the railway and highway to protect the normal running of the train line. If there is no protective fence net, animals may cross the railway, and people around the railway may stray into the railway track area, which will bring major safety hazards. With the development of my country's high-speed rail technology, the railway running speed can reach 350km / h. At such a high speed, if there is no railway fence to isolate people or animals from colliding with the train, it will cause life-threatening, and even The train derailed, causing even greater personnel safety accidents. So far, there are a large number of railway fences on both sides of China's 124,000-kilometer railway line as protective measures to ensure that trains can run ...
