The invention discloses a preparation method of an early-strength water reducing agent special for highways, and relates to the technical field of chemical dyes. The early-strength water reducing agent is prepared from the following components in parts by mass: deionized water, a polycarboxylic acid water reducing agent, modified sodium alginate, triethanolamine and styrene-acrylic emulsion. The preparation method of the early strength water reducing agent comprises the following steps: S1, mixing deionized water, a polycarboxylic acid water reducing agent and triethanolamine, and uniformly conducting stirring at 40 DEG C for 15 minutes to obtain a mixture A; S2, adding modified sodium alginate into the mixture A in the step S1 while stirring to obtain a mixture B; and S3, adding styrene-acrylic emulsion into the mixture B in the step S2, and conducting stirring for 20 minutes to obtain the early-strength water reducing agent. The early-strength water reducing agent special for the highway is simple in preparation method and capable of effectively improving the overall strength of concrete for the highway.
本发明公开了一种公路专用早强减水剂的制备方法，涉及化工染料技术领域。所述早强减水剂由以下质量份数的组分制成：去离子水、聚羧酸系减水剂、改性海藻酸钠、三乙醇胺、苯丙乳液。其中早强减水剂的制备方法如下：S1、将去离子水、聚羧酸系减水剂以及三乙醇胺混合，在40℃的条件下均匀搅拌15min，得到混合物A；S2、在搅拌的同时向步骤S1中所述的混合物A添加改性海藻酸钠，制得混合物B；S3、往步骤S2中所述的混合物B添加苯丙乳液，搅拌时间20min，制得早强减水剂。本申请涉及公路专用早强减水剂，制备方法简单，可以有效改善公路用混凝土的整体强度。
