Heat preservation, moisture preservation and durability improving material for concrete and improving method thereof
The invention discloses a heat preservation, moisture preservation and durability improving material for concrete and an improving method of the heat preservation, moisture preservation and durability improving material. The moisture preservation, heat preservation and durability improving material is pasted to the surface of the concrete coated with a protective agent pre-coating solution in advance through a PET double-faced adhesive tape; a preparation method of the material for moisturizing, heat preservation and durability improvement comprises the steps that a high-barrier-property film is adopted, heat preservation foam is made into a vacuum heat insulation plate through a vacuumizing packaging technology, the vacuum heat insulation plate and the moisturizing material are pasted through a nylon hook-and-loop fastener, and a protective agent is fully absorbed through water-absorbent resin in the moisturizing material. The method has the beneficial effects that heat preservation, moisture preservation and durability improvement are integrated, cracking caused by temperature difference inside and outside the concrete due to large day and night temperature difference is made up, the water loss rate of the concrete surface is reduced, the risk of early-stage shrinkage cracking is reduced, meanwhile, the stored modified protective agent reacts with the pre-coating liquid, the compactness of the concrete surface can be improved, and the durability of the concrete is improved. The concrete durability is improved.
本发明公开了一种混凝土用保温‑保湿‑耐久性提升材料及其提升方法，将具备的保湿‑保温‑耐久性提升材料通过PET双面胶粘贴于预先涂刷有防护剂预涂液的混凝土表面；其中保湿‑保温‑耐久性提升的材料制备方法为：采用高阻隔性薄膜通过抽真空封装技术将保温泡沫制成真空绝热板，通过尼龙魔术贴将真空绝热板与保湿材料粘贴，通过保湿材料中的吸水树脂吸饱防护剂。本发明的有益效果为：该方法集保温‑保湿‑耐久性提升于一体，弥补昼夜温差大导致混凝土内外温差引起的开裂，降低混凝土表面失水速率，减少早期干缩开裂风险，同时，储存的改性防护剂与预涂液反应能提升混凝土表层致密性，提高混凝土耐久性。
