wherein, the filler mainly comprises 15 to 30 parts of barium sulfate sand with 40 to 70 meshes and 10 to 40 parts of other graded sand except the barium sulfate sand.

The raw materials for preparing the radiation-proof ceramic tile bonding mortar contain natural shielding agents (barium sulfate sand with a preferred mesh number), and when the ceramic tile bonding mortar prepared by using the natural shielding agents reaches a certain thickness, the strength of ray penetrating substances can be greatly weakened, so that the radiation-proof purpose is achieved; the modified carbon powder is a resistance type wave-absorbing material, and can form a conductive network after being mixed into a mortar system, so that the wave-absorbing effect is improved. The radiation-proof ceramic tile bonding mortar system takes cement and redispersible latex powder as bonding materials, takes barium sulfate sand with an optimal mesh number and other graded sand except the barium sulfate sand as fillers, and is added with a functional material (modified carbon powder) with a radiation-proof function; the combination of barium sulfate sand with the optimal mesh number and the modified carbon powder and the matching of other optimal components and the dosage proportion thereof greatly enhance the radiation protection performance of the radiation protection tile bonding mortar, and the radiation protection tile bonding mortar has the advantages of excellent cohesiveness, crack resistance, hollowing resistance, aging resistance and low price of the traditional tile bonding mortar and also has excellent radiation protection performance. The method can improve the quality of the electromagnetic environment in the domestic living environment of people and is a development direction for leading the future decoration world.

The graded sand is 50-100 meshes of quartz sand.

The preferable mesh number of the quartz sand can improve the construction performance and the strength of the coating.

The modified carbon powder is conductive carbon black.

The preferred modified carbon powder type has better radiation protection performance.
