Problems solved by technology

The viaduct itself plays a huge role in relieving the pressure of urban traffic, but in recent years, the mileage of the viaduct constructed at high speed has led to more power consumption for lighting, and at present, the whole country is saving energy and reducing emissions. Reducing energy consumption is a big topic at this stage

Embodiment 1

[0031] Preparation method of luminescent powder:

[0032] 1. Standard solution preparation

[0033] Potassium permanganate (KMnO4) with a purity of 99.5%; potassium fluoride (KF,) with a purity of 99%; hydrofluoric acid (HF) with a concentration of 40%, and hydrogen peroxide solution (H2O2) with a concentration of 30%. 99% silicon dioxide (SiO2); 99% purity methanol (CH3OH), 99.7% purity ethanol (CH3CH2OH), 99% purity nitric acid (HNO3), 99% purity ammonia (NH4OH), orthosilicon Acetate ethyl ester (C8H20O4Si), laboratory water is self-made deionized water.

[0034] 2. Preparation steps

[0035] 1) Prepare hydrofluoric acid solution: weigh 10 g of hydrofluoric acid with a balance, put it in a 100ml beaker, then measure 40ml of deionized water, and prepare a hydrofluoric acid solution at normal temperature;

[0036] 2) Add 30ml of hydrofluoric acid solution to the beaker, then add SiO 2 powder, react to generate silicofluoric acid solution;

[0037] 3) Add 3ml of fluorosilici...

Embodiment 2

[0062] The difference from Example 1 is that the particle size of the luminescent powder is 580 mesh.

[0063] Preparation of self-luminous sound insulation screen:

[0064] 1) Special PC board for sound barrier: polycarbonate resin is used as the main component, and drying treatment is carried out before processing. The specific drying temperature is controlled at 115 ° C, and the drying time is 8 hours to reduce the moisture content to below 0.02%. Add 900 parts of polycarbonate resin , 80 parts of luminescent powder, 40 parts of reflective powder, and 20 parts of kaolin were dry mixed for 40 seconds, poured into tap water mixed with 6 parts of naphthalene-based superplasticizer and stirred for 130 seconds, and the obtained mixture was formed into a transparent part by injection molding;

[0065] 2) Super-hydrophobic layer: Dip-coat a layer of super-hydrophobic coating on the PC board of the sound insulation screen formed in step 1).

Abstract

The invention relates to a super-hydrophobic self-luminous sound insulation screen and a preparation method thereof. The super-hydrophobic self-luminous sound insulation screen comprises a sound insulation screen and a super-hydrophobic layer, the surface of the sound insulation screen is coated with the super-hydrophobic layer, the sound insulation screen comprises polycarbonate resin, luminescent powder, reflective powder, kaolin, a water reducing agent and water, and the luminescent powder is K2SiF6: Mn < 4 + >. The sound insulation screen comprises 900 parts of polycarbonate resin, 75-80 parts of the luminescent powder, 30-40 parts of the reflective powder, 15-20 parts of the kaolin, 10 parts of the naphthalene water reducer and 50 parts of the water. Not only can noise pollution to surrounding residents be effectively reduced, but also self-illumination can be achieved for a period of time after sunlight and illumination of an automobile lamp are absorbed, the visual effect is obvious, lamplight illumination is reduced, and energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention belongs to the technical field of sound insulation materials, and in particular relates to a superhydrophobic self-luminous sound insulation screen and a construction method. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Viaduct plays an important role in the whole transportation system, and its value in the process of social operation is irreplaceable. After urban development, the traffic is crowded, the buildings are dense, and the streets are difficult to widen. The use of viaducts can evacuate the traffic density and improve the transportation efficiency. In addition, in highways or railways between cities, in order to avoid cro...
