Preparation method of quick-hardening early-strength sulphoaluminate grouting material and grouting material thereof
The invention discloses a preparation method of a quick-hardening early-strength sulphoaluminate grouting material and the grouting material thereof.The preparation method comprises the following steps that S1, vinyl pyrrolidone, N, N-dimethylacrylamide and acrylate emulsion are mixed, and preliminary mixed liquid is obtained; s2, adding sulphoaluminate clinker into the preliminary mixed liquid to obtain an intermediate mixed product; s3, adding fatty alcohol-polyoxyethylene ether into the intermediate mixed product to obtain a product A; s4, mixing water, phosphogypsum and carbide slag to obtain an alkaline mixed product; s5, adding a regulator and a retarder into the alkaline mixed product to obtain a product B; and S6, mixing the product A and the product B to obtain the prepared quick-hardening early-strength sulphoaluminate grouting material. The grouting material is prepared from the following raw material components: sulphoaluminate clinker, vinyl pyrrolidone, N, N-dimethylacrylamide, acrylate emulsion, fatty alcohol-polyoxyethylene ether, water, phosphogypsum, carbide slag, a regulator and a retarder.
本发明公开了一种快硬早强硫铝酸盐型灌浆料的制备方法及其灌浆料，制备方法包括以下步骤：S1、将乙烯基吡咯烷酮、N，N—二甲基丙烯酰胺、丙烯酸酯乳液混合，得到初步混合液体；S2、在初步混合液体中加入硫铝酸盐熟料，得到中间混合产物；S3、在中间混合产物中加入脂肪醇聚氧乙烯醚，得到A产物；S4、将水、磷石膏、电石渣进行混合，得到碱性混合产物；S5、在碱性混合产物中加入调节剂、缓凝剂，得到B产物；S6、将A产物与B产物进行混合即得到所制备的快硬早强硫铝酸盐型灌浆料。灌浆料的原料成分包括硫铝酸盐熟料、乙烯基吡咯烷酮、N，N—二甲基丙烯酰胺、丙烯酸酯乳液、脂肪醇聚氧乙烯醚、水、磷石膏、电石渣、调节剂、缓凝剂。
