Embodiment 1

[0058] Such as figure 1 The preparation process of energy-saving pavement ceramic particles for a diffuse reflection tunnel includes the following steps:

[0059] mixing green body raw materials to obtain a green body mixture, the green body raw materials including kaolin, quartz, bauxite, albite and potassium feldspar;

[0060] Pressing the green body mixture with a mold to obtain a green body with a texture layer formed on the surface, and calcining the green body;

[0061] The reflective material is prepared, the reflective material is sprayed on the texture layer of the green body, and the ceramic particles covered with the reflective layer on the texture layer are obtained after drying.

[0062] In the above steps, the quartz, bauxite, albite and potassium feldspar in the green body raw materials are respectively dried, crushed, and iron-removed, and then mixed uniformly. Specifically, the quartz, bauxite, albite and potassium feldspar in the green body raw materials ar...

Embodiment 2

[0066] On the basis of Example 1, after the green body mixture is pressed by pressing molding equipment, a second green body with a textured layer on the surface is obtained, such as Figure 3 to Figure 10 As shown, the press molding equipment includes a conveying device 5 on which several lower molds 4 are installed, and also includes a first upper mold 6 and a second upper mold arranged in sequence along the conveying direction of the conveying device 5 1. The first upper mold 6 and the second upper mold 1 are located above the lower mold 4; the first upper mold 6 is used to press the green body mixture with the lower mold 4 to obtain a first green body, The second upper mold 1 is used to press the first blank with the lower mold 4 to obtain the second blank.

[0067] In some embodiments, the first driving device and the second driving device are hydraulic cylinders or air cylinders. In one or more embodiments, both the first cavity of the first upper mold and the second ca...

Embodiment 3～ Embodiment 7

[0073] The ceramic particles P1-P5 were prepared by the preparation process in the foregoing examples.

[0074] The green body raw materials of ceramic particles P1 include 30 parts by weight of kaolin, 10 parts of quartz, 5 parts of bauxite, 20 parts of albite feldspar, and 10 parts of potassium feldspar. The reflective material is calculated by weight percentage and consists of the following components Composition: 33% barium sulfate powder, 11% titanium dioxide powder, 13% pearl powder, 16% glass microsphere powder, 3% antioxidant, 12% film-forming aid, and the balance is organic solvent.

[0075] The green body raw materials of the ceramic particles P2 include 25 parts by weight of kaolin, 8 parts of quartz, 10 parts of bauxite, 30 parts of albite feldspar, and 15 parts of potassium feldspar. The reflective material is composed of the following components by weight percentage: Ingredients: 35% barium sulfate powder, 11% titanium dioxide powder, 16% pearl powder, 13% glass ...

Abstract

The invention discloses a diffuse reflection tunnel energy-saving paving ceramic particle and a preparation process thereof, the preparation process comprises the following steps: mixing green body raw materials to obtain a green body mixture, the green body raw materials comprising kaolin, quartz, bauxite, albite and potassium feldspar; pressing the green body mixture by a mold to obtain a green body with a texture layer formed on the surface, and calcining the green body; and preparing a reflective material, spraying the reflective material on the texture layer of the green body, and drying to obtain the ceramic particles of which the texture layer is covered with the reflective layer. The green body mixture can be effectively compacted through a mold pressing process so that the density of the calcined ceramic particles is remarkably higher than that of white gravel adopted in the prior art, the ceramic particles are higher in bearing capacity and not prone to being crushed, oil stains on the road surface are not prone to permeating into the ceramic particles, and therefore after the ceramic particles are used for a period of time, oil stains can be removed by washing the road surface, the reflecting effect of the road surface is improved, maintenance is more convenient, and the service life is longer.

Description

technical field [0001] The invention relates to the field of energy-saving pavement materials for tunnel pavement, in particular to ceramic particles for diffuse reflection tunnel energy-saving pavement and a preparation process thereof. Background technique [0002] In highway tunnels, especially long tunnels, the light is dim, and driving vision is poor. During the daytime, when the driver drives the vehicle at high speed to approach and enter the road tunnel from a bright natural light environment, due to the low lighting brightness in the tunnel hole and the large difference in brightness between the inside and outside of the tunnel entrance, the driver's visual state will experience a period of discomfort. When entering the entrance of the tunnel, nothing can be seen clearly in the tunnel, which is called "black hole phenomenon". After a long period of time, the driver's vision can gradually return to normal. During the visual recovery period, the resulting vision loss...
