Green low-shrinkage self-leveling tile adhesive and preparation method thereof

The invention relates to a green low-shrinkage self-leveling tile adhesive, which is prepared from the following raw materials in parts by weight: 357.8 to 384.8 parts of Portland cement, 53 to 57 parts of MKPC, 95.4 to 102.6 parts of fly ash, 23.8 to 25.6 parts of nano tin foil ash, fine aggregate which is a mixture of 397.5 to 427.5 parts of zirconium silicide microbeads and 397.5 to 427.5 parts of quartz sand; the concrete is prepared from the following raw materials in parts by weight: 4.2-4.2 parts of water, 3.2-3.4 parts of methyl cellulose, 10.6-11.4 parts of redispersible latex powder, 4.7-6.4 parts of a water reducing agent and 228-265 parts of water. The invention also provides a preparation method of the green low-shrinkage self-leveling tile adhesive. The ceramic tile adhesive has higher bonding strength and low shrinkage, the setting time can be shortened, meanwhile, the fluidity of the ceramic tile adhesive is improved, the ceramic tile adhesive reaches a self-leveling state, and the constructio
