Problems solved by technology

However, the existing high-strength pottery sand does not have a high porosity, so that the phase change material cannot be fully absorbed by the pottery sand, resulting in the combination of the phase change material and the cement. When the road surface is stressed, at each phase change point Stress concentration will occur, which will cause serious damage to the road surface.
Furthermore, when the existing method prepares high-porosity pottery sand, the compressive strength will be greatly reduced, and when used on road surfaces, it is easy to be crushed by driving

[0049] Add 10kg of alumina powder, 0.75kg of calcium carbonate powder, and 0.1kg of dye (iron oxide red) to 20kg of water, ball mill for 4 hours to obtain the first slurry, and then add the first slurry to 200kg of alginic acid with a concentration of 1.5wt%. In the sodium solution, stir evenly to form the second slurry with a solid phase content of 4.7%, wherein the solid phase content in the second slurry=solid phase powder mass / gross slurry weight, solid phase powder mass=alumina powder mass + mass of calcium carbonate powder + mass of dyestuff, total weight of slurry = mass of solid phase powder + mass of sodium alginate solution.

[0050] Add 2.5 kg of gluconolactone powder into the second slurry, then stir evenly, and let stand at 40° C. for 48 hours to obtain the first gel. Among them, due to the slow outflow of H from the outlet of gluconolactone powder + Therefore, there is no obvious gel phenomenon during the stirring process, and the gel is gradually formed only du...

[0054] Add 10kg of zirconia powder, 0.5kg of calcium carbonate powder, 0.5kg of dye (chrome oxide green) to 20kg of water, ball mill for 4 hours to obtain the first slurry, and then add the first slurry to 100kg of alginic acid with a concentration of 2.5wt%. In the sodium solution, stir evenly to form the second slurry with a solid phase content of 8.4%, wherein the solid phase content in the second slurry=solid phase powder mass / gross slurry weight, solid phase powder mass=zirconia powder mass + mass of calcium carbonate powder + mass of dyestuff, total weight of slurry = mass of solid phase powder + mass of sodium alginate solution.

[0055] Add 2.0 kg of gluconolactone powder into the second slurry, stir evenly, and let stand at 50° C. for 36 hours to obtain the first gel. Among them, due to the slow outflow of H from the outlet of gluconolactone powder + Therefore, there is no obvious gel phenomenon during the stirring process, and the gel is gradually formed only during...

Abstract

The invention discloses a colored pavement material and a preparation method of the colored pavement material. The pavement material is prepared from a cementing material, colored cavity gap ceramic grains and a phase change material, wherein a preparation method of the colored cavity gap ceramic grains comprises the following steps: (1) adding water into ceramic powder, calcium carbonate powder and a dyestuff and pulping to prepare first pulp; (2) adding a sodium alginate solution into the first pulp and uniformly mixing to obtain second pulp with the solid phase content of 2 weight percent to 30 weight percent; (3) adding gluconolactone powder into the second pulp and uniformly stirring; standing to generate first gel; (4) dehydrating the first gel under an acidic environment to obtain second gel; (5) carrying out solvent displacement on the second gel to obtain third gel; (6) drying, cutting, sintering and crushing the third gel to obtain the colored cavity gap ceramic grains. According to the colored pavement material disclosed by the invention, the temperature sensitivity of the colored pavement material is effectively reduced and the anti-rutting capability of the pavement material is improved.

Description

technical field [0001] The invention relates to a pavement material and a preparation method thereof, in particular to a colored pavement material and a preparation method thereof. Background technique [0002] Colored pavement has the functions of beautifying the environment and warning traffic. Colored pavement is widely used in Europe to remind road users which part of the road can be used at which time. Colored pavement is widely used in Europe to provide a separate lane for special road users, such as bus lanes dedicated to public transport, bicycle lanes, small motor lanes, electronic toll booths dedicated to emergency services and VIP card holders Lane. Colored roads are distinguished by color on some speed bumps. This distinction is very useful. It can effectively reduce traffic violations and increase traffic safety. In addition, the popularization of colored pavement can greatly change the image of the city and reflect the characteristics of the city. Not onl...
