Example Embodiment
[0021] Example 1
[0022] It is prepared by the following parts by mass: 20 parts of inorganic gelling material, 3 parts of redispersible latex powder, 1.5 parts of cellulose ether, 1.5 parts of PP fiber, 48 parts of quartz sand, 20 parts of heavy calcium powder , 10 parts of light filler, 1.5 parts of anti-shrinking agent, 0 parts of pigment.
[0023] The inorganic cementing material uses Portland cement. The strength grade of Portland cement is 52.5. Redispersible latex powder uses ethylene-vinyl acetate copolymer. The cellulose ether uses HPMC material with a viscosity of 40,000. The specification of quartz sand is 60~80 mesh. Lightweight filler uses 60-120 mesh vitrified beads.
[0024] It is prepared by the above preparation process and is engraved after mechanical spraying.
Example Embodiment
[0025] Example 2
[0026] It is formulated with the following parts by mass: 30 parts of inorganic gelling materials, 3 parts of redispersible latex powder, 1.5 parts of cellulose ether, 1.5 parts of PP fiber, 37 parts of quartz sand, 15 parts of heavy calcium powder , 10 parts of light filler, 1.5 parts of anti-shrinking agent, 0 parts of pigment.
[0027] The inorganic cementing material is a mixture of Portland cement and slaked lime, and the mass ratio of Portland cement and slaked lime is 1:1. The strength grade of Portland cement is 52.5. The calcium hydroxide content in slaked lime is greater than 98%. Redispersible latex powder uses ethylene-vinyl acetate copolymer. The cellulose ether uses HPMC material with a viscosity of 100,000. The specification of quartz sand is 30-60 mesh. The lightweight filler is mixed with vitrified microbeads and 40-80 mesh vermiculite, and the mass ratio of vitrified microbeads and 40-80 mesh vermiculite is 1:1.
