Embodiment 1

[0144] (1) Weigh 50 g of silicate glass powder and disperse it in 50 g of distilled water, add 0.025 g of sodium silicate suspending agent and 0.5 g of cobalt chloride colorant, mix the above powders and carry out mechanical ball milling for 12 h, and After the mixed slurry passes through a 400-mesh sieve, a glaze with stable suspension and uniform dispersion is obtained.

[0145] (2) The obtained glaze is sprayed to form a uniform glaze layer on the surface of the GRC substrate, and dried at 60°C for 30 minutes, and the dried GRC building material is preheated to 400°C, and heated with a flame The hydrogen-oxygen flame at a temperature of 1500 °C was evenly sprayed onto the surface of the GRC substrate, and the residence time was 10 s, so that the glaze layer was rapidly melted and combined with the GRC substrate, and an intermediate layer about 10 μm thick was obtained.

[0146] (3) Apply the glaze slurry obtained in step 1 evenly on the surface of the intermediate layer obt...

Embodiment 2

[0148] (1) Weigh 50 g of borosilicate glass powder and disperse it in 100 g of distilled water, add 0.05 g of polyvinyl alcohol and 1.0 g of ferric chloride, mix the above powders and perform mechanical ball milling for 24 h, and pass the mixed slurry After a 600-mesh sieve, a glaze with stable suspension and uniform dispersion is obtained.

[0149] (2) Form a uniform glaze layer on the surface of the GRC substrate by brushing the obtained glaze, and dry it at 80 °C for 30 min, preheat the dried GRC building material to 500 °C, and The acetylene oxygen flame with a flame temperature of 2000 °C was evenly sprayed onto the surface of the GRC substrate, and the residence time was 5 s, so that the glaze was rapidly melted and combined with the GRC substrate, and an intermediate layer about 20 μm thick was obtained.

[0150] (3) Apply the glaze slurry obtained in step 1 evenly on the surface of the intermediate layer obtained in step 2 by brushing to form a glaze layer, and dry at ...

Embodiment 3

[0152] (1) Weigh 50 g of lead silicate glass powder and disperse it in 25 g of distilled water, add 0.1 g of gum arabic suspending agent and 2.5 g of copper oxide colorant, mix the above powders and carry out mechanical ball milling for 48 h, and put After the mixed slurry is passed through a 200-mesh sieve, a glaze with stable suspension and uniform dispersion is obtained.

[0153] (2) Form a uniform layer of glaze on the surface of the GRC substrate by glazing the obtained glaze, and dry it at 70 °C for 40 min, preheat the dried GRC building material to 300 °C, heat The silicon carbide rod at a temperature of 1000oC heats the glaze on the surface of the GRC substrate for a residence time of 7 s, so that the glaze melts quickly and combines with the GRC substrate to obtain an intermediate layer with a thickness of about 30 μm.

[0154] (3) Apply the glaze slurry obtained in step 1 evenly on the surface of the intermediate layer obtained in step 2 to form a glaze layer by glaz...

Abstract

The invention discloses a colorized GRC product prepared from multi-grading waste glass and a preparation method thereof. The colorized GRC product comprises waste glass composite colorized decorative surface layer and a waste glass composite structural layer. The preparation method comprises the following steps: recycled waste glass is classified according to color, levigated and added to a GRC surface layer so as to prepare the decorative surface layers with specified colors; at the same time, the waste glass with various colors are prepared into fine aggregate and coarse aggregate according to grading so as to prepare the structural layer. According to the invention, the waste glass is adopted to replace aggregate, so that the waste is efficiently utilized, the colorized glass is used as different color tone to replace pigments and to be added to the GRC product, the defects that the pigments are not uniformly distributed and the pollution is serious in the later period are overcome, the artistry of GRC decoration is improved, and various properties of fiber reinforced cement can be improved. The technology is simple, higher economical and environmental benefits are obtained, and high value-added resource utilization is realized.

Description

technical field [0001] The invention belongs to the field of building decoration materials, in particular to a method for preparing colored GRC products from multi-gradation waste glass. Background technique [0002] Glass is a huge consumption item in daily life. If it is not recycled and utilized effectively, it will become the main pollutant of urban garbage, which not only wastes resources but also damages the environment. my country's current waste glass recycling rate is only 13%, and a large amount of waste glass has not been effectively recycled. If waste glass is used as raw material for firing glass again, the requirements for color and type are relatively high, and the benefits are not obvious. At present, in China, a small part of the waste glass produced in daily life is recycled in waste collection stations through various means, and most of the rest are landfilled by the sanitation department. Landfill treatment not only wastes a lot of renewable resources, ...
