Anti-crack gypsum mortar capable of effectively filling cracks or holes and preparation method of anti-crack gypsum mortar
The invention discloses anti-crack gypsum mortar capable of effectively filling cracks or cavities. The anti-crack gypsum mortar is prepared from the following raw materials in parts by weight: 150-200 parts of gypsum powder, 55-85 parts of desulfurized gypsum, 35-55 parts of ardealite-based gypsum powder, 0.1-0.5 part of a retarder, 0.1-0.5 part of a waterproof agent, 0.1-0.5 part of a water reducing agent, 1-5 parts of anti-crack fibers and 0.5-1.0 part of rubber powder. The anti-cracking gypsum mortar disclosed by the invention can effectively inhibit plastic cracking of the gypsum mortar, does not fall off or crack during construction or under the action of long-term self weight and environment, can effectively protect walls and grounds from being eroded by wind, rain and harmful impurities, improves moisture resistance, corrosion resistance and weather resistance, and increases durability.
本发明公开了一种有效填充裂缝或空洞的抗裂石膏砂浆，由以下重量份的原料制成：石膏粉150～200份、脱硫石膏55～85份、磷石膏基石膏粉35～55份、缓凝剂0.1～0.5份、防水剂0.1～0.5份、减水剂0.1～0.5份、抗裂纤维1～5份、胶粉0.5～1.0份。本申请抗裂石膏砂浆能够有效抑制石膏砂浆塑性开裂，在施工中或长期自重和环境作用下不脱落、不开裂，可有效保护墙体、地面不受风雨及有害杂质的侵蚀，提高防潮、防腐蚀、抗风化性能，增加耐久性。
