[0107] 1. Performance Testing

[0108] Wear resistance determination: According to the "Test Method for Wear Resistance of Inorganic Floor Materials" (GB / T12988-2009), the cement tiles prepared in Examples 1-3 and Comparative Examples 1-5 were tested for wear resistance. In addition, the cement colored tiles purchased on the market, which were purchased from Lehong, were tested together as a control group. The wear rates of the cement colored tiles and cement colored tiles after 30 minutes were calculated. The specific formula is:

[0109] Wear rate = (ab) / a×100%, where a is the mass of the tile before the test and b is the mass after the test;

[0110] Flexural strength test: The flexural strength test was performed on the cement tiles obtained in Examples 1-3 and Comparative Examples 6-7 and the control group according to the flexural strength of Jc410-91 cement tiles.

[0111] The above test results are shown in Table 1.

[0112] Table 1 Test results

[0113]

[0114]

[0115] It can be concluded from Table 1 that the wear rate of Examples 1-3 is lower than that of Comparative Examples 1-5 and the control group, while the flexural strength is higher than that of Comparative Examples 6-7 and the control group. No wear-resistant filler was added in Comparative Example 1-2, and its wear resistance decreased; Comparative Example 3 used modified graphene, and its bonding with cement decreased, thereby affecting wear resistance; the emulsifiers in Comparative Examples 4-5 were relatively single, and their dispersion effect was not ideal, which made the wear resistance effect worse; Comparative Examples 6-7 lacked quartz sand in the middle layer material or albite in the bottom layer material, and no sodium silicate calcium salt was generated, so the bonding between the layers decreased, and the flexural strength was greatly reduced.
