Organic-inorganic composite modified concrete external curing agent and preparation method thereof
The invention discloses an organic-inorganic composite modified concrete external curing agent and a preparation method thereof. The organic-inorganic composite modified concrete external curing agent is prepared by mixing 100-150 parts by weight of polyvinyl ether terpyridyl modified styrene-acrylic emulsion, 8-16 parts by weight of sodium silicate nonahydrate, 15-30 parts by weight of polyethylene glycol, 1-1.5 parts by weight of a defoaming agent, 1-1.5 parts by weight of a flatting agent and 20-50 parts by weight of deionized water. The concrete surface treating agent is sprayed or coated on the concrete surface, can quickly form a thin compact film on the surface, has good environmental adaptability, can effectively work under various weather conditions, ensures that water in the concrete is retained, and promotes sufficient hydration of cement, so that the overall performance of the concrete is improved, and the service life of the concrete is prolonged. And meanwhile, the cost benefit and the environmental friendliness are good, and the sustainable development goal of concrete construction and maintenance can be achieved.
本发明公开了一种有机无机复合改性混凝土外养护剂及其制备方法，由聚乙烯基醚三联吡啶改性苯丙乳液100‑150重量份、九水硅酸钠8‑16重量份、聚乙二醇15‑30重量份、消泡剂1‑1.5重量份、流平剂1‑1.5重量份和去离子水20‑50重量份混合制备而成。本发明喷涂或涂覆在混凝土表面，能够快速在表面形成一薄层致密的薄膜，具备良好的环境适应性，能够在各种气候条件下有效工作，确保混凝土内部水分得以保留，促进水泥充分水化，从而提高混凝土的整体性能和延长其使用寿命。同时本发明的成本效益和环境友好性均表现良好，有助于实现混凝土施工和养护的可持续发展目标。
