聚合物水泥基涂层材料是一种应用于混凝土表面防护的有机-无机复合涂层。其兼具水泥的刚性和聚合物的柔韧性，但存在着聚合物乳液成膜快而水泥水化慢的矛盾会导致其抗裂性不足。针对该问题，本文通过引入玻璃纤维实现聚合物水泥基涂层抗裂性能的提升。系统研究了玻璃纤维对聚合物水泥基涂层材料流动度、动力粘度、拉伸性能、粘接强度及水化产物的分析。实验结果表明，添加0.2%的玻璃纤维后，相较不掺入纤维在28龄期时的拉伸强度提高了60%，断裂伸长率提高了16%，粘接强度提高了10.4%，且浆体的动力粘度增加，水化产物含量得到提高。

Polymer cement-based coating material is an organic-inorganic composite coating applied for protective purposes on concrete surfaces. It combines the rigidity of cement and the flexibility of polymers, but the contradiction between the fast film formation of polymer emulsion and the slow hydration of cement leads to insufficient crack resistance. To address this issue, this paper improves the crack resistance of polymer cementbased coatings by introducing glass fibers. A systematic study was conducted on the fluidity, dynamic viscosity, tensile properties, adhesive strength, and hydration products of polymer cement-based coating materials with glass fibers. The experimental results show that after adding 0.2 % glass fibers, compared with the case without fibers, the tensile strength at 28 days was increased by 60 %, the elongation at break was increased by 16 %, the adhesive strength was increased by 10.4%, the dynamic viscosity increases, and the content of hydration products was increased.
