The invention relates to anti-cracking mortar powder for thin plastering and leveling of inner walls and a preparation method of the anti-cracking mortar powder. The anti-cracking mortar powder for thin plastering and leveling of inner walls is prepared from the following raw materials: in parts by weight, 17-25 parts of a cementing material, 0-10 parts of active filler, 0-5 parts of inert filler,70-75 parts of aggregate, 0.1-0.2 part of a water-retaining thickener, 0-0.8 part of an adhesive, 0-0.5 part of a binder, 0.2-0.3 part of a water-conducting thickener, 0.05-0.15 part of crack-resistant fiber, 0-0.5 part of a slipping agent and 0-0.1 part of a thixotropic agent. The mortar powder has good water resistance, high strength, no easy cracking, no indoor environmental pollution and goodworkability. 本发明涉及内墙薄抹灰找平抗裂砂浆粉料及其制备方法。内墙薄抹灰找平抗裂砂浆粉料，由以下原料按重量份配比制成：胶凝材料17～25份、活性填料0～10份、惰性填料0～5份、骨料70～75份、保水增稠剂0.1～0.2份、胶粘剂0～0.8份、粘接剂0～0.5份、导水增稠剂0.2～0.3份、抗裂纤维0.05～0.15份、爽滑剂0～0.5份、触变剂0～0.1份。本发明提供的砂浆粉料耐水性好、强度高、不易开裂、无室内环境污染和施工性好。
