Macromolecular powdery adhesive capable of improving adhesive strength of cement and soil
The invention discloses a macromolecular powdery adhesive capable of improving the adhesive strength of cement and soil, which is prepared from the following components in parts by weight: 3-10 parts of allophanate, 2-4 parts of polyvinyl alcohol, 2-3 parts of water reducing agent, 2-5 parts of polyurethane, 5-10 parts of sodium silicate, 1-3 parts of lignosulfonate, 1-3 parts of calcium stearate, 1-2 parts of super absorbent resin, 5-7 parts of a corrosion inhibitor and 10-50 parts of epoxy resin. The cement soil has the beneficial effects that by adding the corrosion inhibitor, allophanate, polyvinyl alcohol and the water reducer, the application function of the cement soil is effectively improved, corrosion to iron buildings is reduced, the cement soil has very high durability, the dosage of cement is reduced, the firmness of a cement pattern is improved, and the water reducer has a dispersion effect on cement particles, the workability can be improved, the unit water consumption is reduced, the fluidity of a mixture is improved, the unit cement consumption is reduced, and the cement is saved.
本发明公开了一种可提高水泥与泥土粘合强度的高分子粉状粘合剂，以重量份计，所述粘合剂包括脲基甲酸酸酯：3份‑10份，聚乙烯醇：2份‑4份，减水剂：2份‑3份，聚氨酯：2份‑5份，硅酸钠：5份‑10份，木质磺酸盐：1份‑3份，硬脂酸钙：1份‑3份，高吸水性树脂：1份‑2份，阻锈剂：5份‑7份，环氧树脂：10份‑50份。本发明的有益效果是：本发明通过添加阻锈剂、脲基甲酸酸酯、聚乙烯醇和减水剂，有效提高了水泥土的应用功能，减少对铁建筑的腐蚀，具有很高的耐久度，减少了水泥的用量，提高了水泥图的坚固性，减水剂对水泥颗粒有分散作用，能改善其工作性，减少单位用水量，改善拌合物的流动性，减少单位水泥用量，节约水泥。
