Waterproof sealant at joints of prefabricated external wall panels of prefabricated buildings and production process thereof
The invention discloses a waterproof sealant at joints of prefabricated external wall panels of prefabricated buildings and a production process of the waterproof sealant. The waterproof sealant comprises an MS polymer, polyether polyol, nano calcium carbonate, polyamide wax, a coupling agent, a catalyst, fumed silica, dibutyltin dilaurate, nano diatomite, an antibacterial agent, a cross-linking agent, a flame retardant, an ultraviolet absorbent, a curing agent, a curing accelerator and absolute ethyl alcohol. The waterproof sealant at the joints of the prefabricated external wall panels of the prefabricated buildings has the advantages of high waterproof performance, good weather resistance, high cohesiveness, short surface drying time, high tensile strength, high elongation at break, high hardness, high corrosion resistance, high falling resistance, long service life, no toxicity, low cost and the like, and is suitable for large-scale popularization and application. The sealant is ahigh-performance waterproof sealant; the sealant has the advantages that the stress is mild, the sealant has stress and elasticity at the same time, and even if the sealant is in a stretched state fora long time, the influence caused by shrinkage of building base materials can be eliminated to the maximum extent under the action of stress relaxation.
本发明公开了装配式建筑预制外墙板接缝处的防水密封胶及其生产工艺，包括MS聚合物、聚醚多元醇、纳米碳酸钙、聚酰胺蜡、偶联剂、催化剂、气象二氧化硅、二丁基二月硅酸锡、纳米硅藻土、抗菌剂、交联剂、阻燃剂、紫外吸收剂、固化剂、固化促进剂和无水乙醇。该装配式建筑预制外墙板接缝处的防水密封胶具有以下优点：该密封胶具有高强的防水性能，耐候性好，粘结性强，表干时间快，拉伸强度大，断裂伸长率大，硬度强等优点，具有高强的防腐蚀、防脱落性能，使用寿命长，而且无毒，是高性能的防水密封胶；应力缓和，该密封胶同时兼具应力和弹性，即使长期处于拉伸状态，在应力缓和的作用下，可最大限度地消除建筑基材收缩带来的影响。
