Magnesium phosphate-based repair material
The invention discloses a magnesium phosphate-based repairing material, and relates to the field of building materials. The repairing material is prepared from the following raw materials in percentage by mass: 30-50% of magnesium phosphate cement, 5-20% of fly ash microspheres, 1-6% of modified polymer rubber powder, 3-6% of a retarder, 0.1-1% of a water-retaining agent, 30-50% of graded sand andthe balance of water. The preparation method comprises the following steps: weighing the raw material components according to the ratio, carrying out dry stirring for 60 s, adding water, carrying outlow-speed stirring for 30 s to preliminarily react the raw materials with water, and carrying out high-speed stirring for 90 s to make the raw materials uniform. According to the invention, by optimizing the ratio of dead burnt magnesite powder to potassium dihydrogen phosphate and adding fly ash and polymer rubber powder, the bonding strength of the material is improved, firm bonding with an original interface is ensured, the durability is improved, meanwhile, the setting time and the construction performance are adjusted through the retarding component and the water retention component, anda good construction effect is achieved.
本发明公开了一种磷酸镁基修补材料，涉及建筑材料领域。该修补材料由以下质量百分比的原料组成：磷酸镁水泥30％‑50％、粉煤灰微珠5％‑20％、改性聚合物胶粉1％‑6％、缓凝剂3％‑6％、保水剂0.1％‑1％、级配砂30％‑50％，余量为水。按照配比称量原料组分干搅60s，加水先低速搅拌30s使所述原料与水初步反应，再高速搅拌90s使其均匀。本发明通过优化重烧镁粉和磷酸二氢钾的配比，并添加粉煤灰和聚合物胶粉提升材料的粘结强度，保证与原界面粘结牢固，提升耐久性,同时通过缓凝组分和保水组分调节凝结时间和施工性能，具有良好的施工效果。
