Organic-inorganic hybrid grouting material for low-temperature reinforcement as well as preparation method and application of organic-inorganic hybrid grouting material
The invention discloses an organic-inorganic hybrid grouting material for low-temperature reinforcement as well as a preparation method and application of the organic-inorganic hybrid grouting material, and belongs to the technical field of grouting reinforcement. The grouting material comprises a component A and a component B, the component A is prepared from the following inorganic raw materials in parts by weight: 65 to 80 parts of silicate solution, 10 to 25 parts of coupling agent and 3 to 6 parts of catalyst; the component B is prepared from the following organic raw materials in parts by weight: 65-85 parts of isocyanate substances, 20-30 parts of a flow modifier, 5-15 parts of a flexibilizer and 25-40 parts of an anti-freezing agent. During use, the component A and the component B are mixed according to the volume ratio of 1: 1 for grouting. The grouting material consolidation body is high in compressive strength and good in toughness, can meet most engineering requirements, can obviously enhance connection of a to-be-reinforced part, and improves the strength of a to-be-reinforced body; the grouting material is good in cold resistance, still has excellent flowability at the temperature below 0 DEG C, can effectively fill rock fractures, and is suitable for being used in extremely severe environments.
本发明公开了一种低温加固用有机无机杂化注浆材料及其制备方法与应用，属于注浆加固技术领域。所述注浆材料包括A、B两组分；A组分由如下重量份的无机原料组成：硅酸盐溶液65～80份、偶联剂10～25份、催化剂3～6份；B组分由如下重量份的有机原料组成：异氰酸酯类物质65～85份、流动改性剂20～30份、增韧剂5～15份、耐寒剂25～40份。使用时将A、B组分按体积比1：1混合注浆。所述注浆材料固结体抗压强度较高，韧性好，可以满足绝大部分工程需求，能明显增强待加固部分的连接，提高待加固体强度；所述注浆材料耐寒性好，在0℃以下仍具有优秀的流动性，可有效充满岩石裂隙，适合在极端恶劣环境中使用。
