Concrete zero-intermittent polyurethane maintenance protection reinforcing material and preparation method thereof
The invention relates to a concrete zero-intermittent polyurethane maintenance protection reinforcing material and a preparation method thereof. The reinforcing material sequentially comprises an adhesive layer with controllable attenuation strength, a maintenance protection layer and a concrete bonding layer, the concrete layer and the steel formwork for concrete forming form a whole through the adhesive layer, and the joints of the adhesive layer, the maintenance protection layer and the concrete layer are fused into a non-layered whole. Wherein the maintenance protective layer is prepared from the following components in parts by weight: 80 to 100 parts of polyurethane light-cured resin, 0.2 to 0.8 part of a photoinitiator, 20 to 25 parts of a diluent and 3 to 5 parts of surface modified nano silicon dioxide; the concrete bonding layer is composed of superfine magnesium oxychloride cement; the initial bonding strength of the adhesive is 1.2 MPa, and the adhesive can be used for bonding a maintenance protective layer and a steel template for concrete forming; the bonding strength is 0.05 MPa along with the extension of time, and the steel formwork can be separated from the steel formwork for concrete forming.
本发明涉及一种混凝土零间歇聚氨酯养护防护增强材料及其制备方法，增强材料依次包括：强度可控衰减的胶黏剂层、养护防护层和混凝土粘结层；其通过所述胶黏剂层与混凝土成型用钢模板形成一个整体，所述胶黏剂层、养护防护层和混凝土层之间连接处相互融合成不分层的整体；其中，所述养护防护层按重量计包含以下组分：聚氨酯光固化树脂80‑100份、光引发剂0.2‑0.8份、稀释剂20‑25份、表面改性的纳米二氧化硅3‑5份；所述混凝土粘结层由超细氯氧镁水泥组成；所述胶黏剂初始粘结强度为1.2MPa能够粘结养护防护层和混凝土成型用钢模板；随着时间的延长其粘接强度为0.05MPa，能够与所述混凝土成型用钢模板分离。
