Outer wall surface anti-crack waterproof material for constructional engineering and preparation method of outer wall surface anti-crack waterproof material
The invention is applicable to the technical field of waterproof materials, and provides an outer wall surface anti-crack waterproof material for constructional engineering. The outer wall surface anti-crack waterproof material comprises the following components in parts by weight: 100-120 parts of cement, 30-50 parts of fly ash, 25-45 parts of a modified emulsified polyphenyl coating, 12-20 parts of a shrinkage-reducing anti-crack reinforcing agent, 20-40 parts of crack-resistant fibers, 1-5 parts of a penetrant, 1-5 parts of a defoaming agent, 1-5 parts of a thickening agent and 30-50 parts of deionized water. The invention also provides a preparation method of the outer wall surface anti-crack waterproof material for constructional engineering, the modified emulsified asphalt obtained by modifying the emulsifier is used as a coating agent, a coating layer is formed on the surface of the polyphenyl particles, and the water resistance and crack resistance of the material are improved by performing surface coating modification on the polyphenyl particles; and the shrinkage-reducing anti-crack reinforcing agent is also added, and various functional groups are introduced into side chain active groups of a molecular chain with a comb-shaped structure through cross-linking condensation copolymerization, so that the crack resistance and long-term durability of the waterproof material are improved.
本发明适用于防水材料技术领域，提供了一种建筑工程的外墙面抗裂防水材料，包括以下按照重量份的组分：水泥100～120份、粉煤灰30～50份、改性乳化聚苯包覆物25～45份、减缩抗裂增强剂12～20份、抗裂纤维20～40份、渗透剂1～5份、消泡剂1～5份、增稠剂1～5份和去离子水30～50份。本发明还提供了一种如上所述的建筑工程的外墙面抗裂防水材料的制备方法，将乳化剂改性处理得到的改性乳化沥青作为包覆剂，在聚苯颗粒表面形成包覆层，通过对聚苯颗粒进行表面包覆改性，提高材料的耐水性和抗裂性能；还添加有减缩抗裂增强剂，通过交联缩合共聚成梳状结构的分子链侧链活性基团引入多种官能团，以提高防水材料抗裂性及长期耐久性。
