The invention relates to inorganic rubber powder composite powder and a preparation method thereof, and the inorganic rubber powder composite powder comprises the following components in parts by weight: 200-360 parts of sodium silicate, 4-8 parts of calcium formate, 300-360 parts of silica fume, 120-200 parts of water, 5-20 parts of an additive, 50-80 parts of mineral powder, 10-20 parts of polyoxyethylene, 30-50 parts of zinc oxide and 3-5 parts of xanthan gum. The additive is alkali metal salt or alkali metal hydroxide. According to the inorganic rubber powder composite powder provided by the invention, the selected materials are all non-toxic and harmless inorganic metal minerals, the sources of the materials are wide, the inorganic rubber powder composite powder can replace high-consumption, high-pollution and non-renewable materials which are massively used in the existing refining and synthesizing process of redispersible latex powder, and the produced inorganic composite rubber powder hardly has an interface transition region with aggregate, the interface bonding is good, and the interface bonding strength in the mortar can be improved.
本发明涉及一种无机胶粉复合粉及其制备方法，其中无机胶粉复合粉以重量份数计，包括硅酸钠200‑360份、甲酸钙4‑8份、硅灰300‑360份、水120‑200份、添加剂5‑20份，矿粉50‑80份、聚氧化乙烯10‑20份、氧化锌30‑50份和黄原胶3‑5份；所述的添加剂为碱金属盐或碱金属氢氧化物。本发明申请提供的无机胶粉复合粉选用的材料均为无毒无害的无机金属矿物，材料来源广泛，能代替现有的可再分散乳胶粉提炼合成过程中大量使用的高耗高污染不可再生的材料，生产出的无机复合胶粉与骨料几乎没有界面过渡区，界面胶结很好，可提高砂浆中界面粘接强度。
