Strength growth type polyurethane cement mortar facade repairing material and preparation
The invention discloses a strength growth type polyurethane cement mortar facade repairing material and a preparation method thereof. The repairing material is prepared from the following raw materials in parts by weight: 15-42 parts of double-component thermosetting polyurethane, 50-70 parts of fine sand, 30-50 parts of cement and 1.15-4.26 parts of a thixotropic agent. The bi-component thermosetting polyurethane is prepared from a polyhydric alcohol component and an isocyanate component, and the bi-component thermosetting polyurethane is prepared from the following components in parts by weight: 10 to 28 parts of the polyhydric alcohol component and 5 to 14 parts of the isocyanate component; the total weight of the fine sand and the cement is 100 parts. According to the strength growth type polyurethane cement mortar facade repairing material and the preparation method thereof, the prepared repairing material has the advantages of high strength, high corrosion resistance, high cohesiveness, high impermeability, high freezing resistance, good wear resistance, high impact resistance, convenience in construction and the like, and is good in sagging resistance; the cement can be subjected to hydration reaction with infiltrated moisture, so that the strength of the repairing material is continuously enhanced.
本发明公开了一种强度成长型聚氨酯水泥砂浆立面修复材料及制备方法，修复材料由以下重量份的原料配比制成：15～42份双组分热固性聚氨酯，50～70份细砂，30～50份水泥，1.15～4.26份触变剂；所述双组分热固性聚氨酯由多元醇组分和异氰酸酯组分组成，其按重量份配比组成为10～28份多元醇组分、5～14份异氰酸酯组分；所述细砂和水泥总重量为100份。本发明采用上述的一种强度成长型聚氨酯水泥砂浆立面修复材料及制备方法，制备的修复材料具有强度高、耐腐蚀性强、黏结性强、抗渗性高、抗冻性强、耐磨性好、抗冲击性高和施工方便等优点，抗流挂性能好，水泥可与渗入的水分发生水化反应，持续增强修复材料的强度。
