TABLE 1 wear Rate of ceramic colored sand
As can be seen from Table 1, the abrasion rate of the ceramic sand grains in examples 1-6 is lower than 1.35%, and the abrasion rate of the ceramic colored sand in example 1 is lower than that of example 12 in comparison with examples 1, namely, basalt is used as main aggregate, and is compounded with aluminum dihydrogen phosphate and inorganic pigment, and high-temperature sintering is carried out to obtain the ceramic colored sand which has excellent abrasion resistance, is not easy to fade and has better color retention. The abrasion rate of the ceramic sand grains in examples 13-14 is lower than 0.95%, and the abrasion rate of the ceramic colored sand grains in examples 13-14 is lower than that in examples 1, compared with examples 13-14, which shows that sodium hydrogen tartrate (water) is added in the process of preparing the ceramic colored sand, so that aluminum dihydrogen phosphate and inorganic pigment can be uniformly attached to main aggregate basalt, and the abrasion resistance of the ceramic colored sand is improved, so that the ceramic colored sand has better color retention performance.
(3) Boiling water resistance test

After the ceramic sand grains in examples 7-11 are soaked in boiling water for 30min, the water is free from obvious discoloration and turbidity, and the colored sand is free from caking phenomenon, which indicates that the addition of the acesulfame potassium in the process of preparing the ceramic colored sand has no negative influence on the boiling water resistance of the colored sand. After the ceramic sand grains in examples 13-14 are soaked in boiling water for 30min, the water is free from obvious discoloration and turbidity, and the color sand is free from caking phenomenon, which indicates that sodium hydrogen tartrate (water) is added in the process of preparing the ceramic color sand, and the water-resistant performance of the color sand is free from negative influence.

TABLE 3 results of acid and alkali resistance test of ceramic colored sand
As can be seen from Table 3, after the ceramic sand grains in examples 1-6 are respectively soaked in sulfuric acid solution and sodium hydroxide solution for 24 hours, water does not change color or become turbid obviously, which indicates that the ceramic colored sand prepared by the method has good color retention performance, but the colored sand has a small amount of agglomeration phenomenon, and the colored sand part is possibly eroded by acid-base solution, so that the agglomeration phenomenon occurs; comparing examples 1-6 with example 12, the acid and alkali resistance of the ceramic colored sand in examples 1-6 is better than that of example 12, which shows that the invention uses basalt as main aggregate, and the basalt is compounded with aluminum dihydrogen phosphate and inorganic pigment, and the ceramic colored sand is obtained by high-temperature sintering, which has excellent wear resistance, is not easy to fade, and has better color retention. After the ceramic sand grains in examples 7-11 are respectively soaked in sulfuric acid solution and sodium hydroxide solution for 24 hours, water does not change color or become turbid obviously, and the colored sand does not have a caking phenomenon, which proves that the acid-base resistance of the ceramic colored sand is improved by adding acesulfame potassium in the process of preparing the ceramic colored sand.

As can be seen from Table 1, the crushing value of the ceramic sand grains in examples 1-6 is lower than 12%, and the crushing value of the ceramic colored sand in example 1 is lower than that in example 12, which indicates that basalt is used as main aggregate, compounded with aluminum dihydrogen phosphate and inorganic pigment, and sintered at high temperature to obtain the ceramic colored sand which has excellent mechanical properties, compact internal structure and regular shape. The crushing value of the ceramic sand grains in examples 7-11 is lower than 10%, and the crushing value of the ceramic colored sand in examples 7-11 is lower than that of example 1 in comparative examples 1 and examples 7-11, which shows that the addition of potassium acesulfame during the preparation of the ceramic colored sand can lead the aluminum dihydrogen phosphate and the inorganic pigment to be uniformly attached to the main aggregate basalt, thereby improving the mechanical property of the ceramic colored sand; the crushing value of the ceramic colored sand in the comparative examples 7-11 and examples 7-9 is lower than 7% and lower than examples 10-11, and the fact that the adding amount of the acesulfame potassium is 1.5-3.5 wt% of the main aggregate can further improve the mechanical property of the ceramic colored sand, and meanwhile, the ceramic colored sand has a compact internal structure and a regular round shape, and can meet the use standard.

In addition, the reflectivity of the ceramic sand grains in examples 7-11 is higher than 94.5%, the reflectivity of the sand grains applied to the SBS coiled material is higher than 88%, the reflectivity of the ceramic colored sand in comparative examples 1 and examples 7-11 and the reflectivity of the ceramic colored sand in examples 7-11 are both higher than those in example 1, and it is explained that the addition of acesulfame potassium in the process of preparing the ceramic colored sand can enable the aluminum dihydrogen phosphate and the inorganic pigment to be uniformly attached to the main aggregate basalt, so that the ceramic colored sand with higher reflectivity is obtained; the comparative examples 7-11, examples 7-9, both the reflectivity of the ceramic colored sand and the reflectivity on the SBS coiled material were higher than those of examples 10-11, demonstrate that the ceramic colored sand with better reflectivity can be obtained and can be better applied to the SBS coiled material when the addition amount of the acesulfame potassium is 1.5-3.5 wt% of the main aggregate.
