[0124] Table 1: Test data record table

[0125]

[0126] It can be seen from Table 1 that compared with the comparative example, the flexible light-transmitting sheets prepared in Examples 1-3 have excellent performance in light transmittance, bending strength and wear resistance, and the flexible light-transmitting sheets with better over-temperature time can maintain fire resistance for a certain period of time under extreme conditions such as fire, and have better side fire resistance. High light transmittance means that the flexible light-transmitting sheet can transmit light more effectively, making the light passing through the light-transmitting sheet softer and more uniform, thereby improving the visual effect and brightness. High bending strength means that the flexible light-transmitting sheet has good flexibility and toughness, which expands its application range. Good wear resistance means that the light-transmitting sheet can resist external friction and wear, extend its service life and maintain a good appearance.

[0127] The present invention prepares a flexible light-transmitting sheet by mixing natural rock modified soil with a light-transmitting fiber material, and has excellent light transmittance and wear resistance. The light-transmitting sheet with excellent wear resistance can maintain a clear and bright surface during long-term use, reducing maintenance and replacement costs. The high light transmittance makes the light passing through the light-transmitting sheet softer and more uniform, thereby improving the visual effect and brightness. The flexible light-transmitting sheet has excellent bending strength and is not easily damaged or cracked under conditions of bending or curving. This enables the light-transmitting sheet to adapt to various complex curved surfaces or shapes, making it easier to install and use, and maintaining stable use in high temperature environments.
