Embodiment 1

[0027] Table 1 Mixing gradation of brick powder.

[0028]

[0029] Such as figure 1 As shown, the luminous layer is composed of PET and luminous powder. During the production process, the mass ratio of phosphor to PET is 1:2. PET material is melted first, and after it becomes liquid, phosphor is applied and stirred evenly with PET for later use. In the production process of the functional layer, mix and grade PET, fly ash and brick powder as shown in Table 1 according to the mass ratio of coal ash, PET and brick powder as 1:9:20, and heat and melt at 300°C after mixing evenly. The heating time is 2h. During the heating process, ventilation should be maintained and the test mold should be heated at the same time as the above-mentioned mixture. After the PET is completely melted, stir evenly, quickly pour it into the heating test mold, vibrate, compact, and level off. The mixture of liquid PET and luminous powder is filled and filled, placed in an oven, adjusted to 200°C, c...

Embodiment 2

[0031] Make molds according to the size of the luminous square bricks such as figure 2 , the mold is a cuboid with five sides closed and one side with an opening for filling the mixture. In the manufacturing process, a movable steel plate 3 is left on the upper part, which can be drawn out and has a thickness of 2 mm. First, the functional layer 2 is as shown in Table 1. The brick powder mixing gradation shown is based on the mixture of fly ash, PET and brick powder with a mass ratio of 1:9:20. After mixing evenly, heat and melt at 300°C for 2 hours. The mixture of light-emitting layer 1 is heated and melted according to the mass ratio of phosphor powder and PET of 1:2. Put the functional layer mixture into the mold for extrusion molding, and then image 3 Pull out the movable steel plate 3, pour the light-emitting layer mixture, and extrude again. During the two extrusions and filling the mixture, the temperature of the mold should be above 200°C. After the second extrusion...

Abstract

The invention discloses a luminous PET-brick powder building block, comprising a luminous layer and a functional layer, wherein the luminous layer is composed of noctilucent powder and PET in a mass ratio of 1: 2, the functional layer is composed of fly ash, PET and brick powder in a mass ratio of 1: 9: 20, and the thickness of the luminous layer is 2 mm. The luminous PET-brick powder building block is applicable as a road marking laying material, an urban square laying material, an urban road manhole cover, a building peripheral load bearing wall, etc. The luminous layer hardly wears and falls off and has good endurance; PET has good light transmission performance and an excellent fluorescent effect, and while regenerated resources are cyclically used, consumption of electric energy and environmental pollution are reduced. The functional layer of the building block has good mechanical properties, compressive strength of 40 MPa, rupture strength of 12 MPa, impervious performance, corrosion resistance and a water absorption rate of less than 1%.

Description

technical field [0001] The invention belongs to the field of decorative building materials, in particular to a luminescent PET-brick powder building block. Background technique [0002] With the development of the economy, more and more cities attach importance to the application of luminous buildings. While beautifying the city, luminous buildings also consume a lot of power resources. According to statistics, the total power of lighting in Tiananmen Square alone reaches 100kW. As a public facility, the square is lit for more than 9 hours a day on average. The lighting alone consumes a lot of electricity every year. A large part of the lighting of luminous buildings is decorative lighting, which does not require high brightness. The use of lighting fixtures undoubtedly produces huge energy waste. [0003] PET bottles have the advantages of impact resistance, transparency, non-toxicity, high barrier properties and low price, and have gradually become the preferred material ...
