Polymer cement concrete additive and preparation method thereof
The invention discloses a preparation method of a polymer cement concrete additive, which is characterized by comprising the following steps: S1, polymerizing 2,6-bis (oxirane-2-methyl)-1, 2, 3, 5, 6,7-hexahydropyrrolo[3,4-f]isoindole-1, 3, 5, 7-tetraketone, ethylenediamine-N,N'-diacetic acid to obtain an intermediate product; S2, preparing hydroxymethyl sulfonic hyperbranched polyglycidyl ether;and S3, preparing the concrete additive. The invention also provides the polymer cement concrete additive prepared by the preparation method of the polymer cement concrete additive. The polymer cement concrete additive provided by the invention has the advantages of multiple functions, obvious improvement of the comprehensive performance of concrete, small mixing amount, higher water reducing rate, capability of effectively improving the strength, durability, workability and cohesiveness of the concrete, remarkable plasticizing effect, good adaptability to the concrete, and safety and environmental protection in use.
本发明公开了一种高分子水泥混凝土添加剂的制备方法，其特征在于，包括如下步骤：步骤S1、2,6‑二(环氧乙烷‑2‑甲基)‑1,2,3,5,6,7‑六氢吡咯并[3,4‑f]异吲哚‑1,3,5,7‑四酮、乙二胺‑N,N'‑二乙酸聚合制得中间产物；步骤S2、羟甲基磺酸基超支化聚缩水甘油醚的制备；步骤S3、混凝土添加剂的制备。本发明还提供了一种根据所述一种高分子水泥混凝土添加剂的制备方法制备得到的高分子水泥混凝土添加剂。本发明提供的高分子水泥混凝土添加剂功能多样，提高混凝土综合性能明显，掺量少，具有较高的减水率，能有效改善混凝土的强度、耐久性、和易性和粘聚性，增塑效果显著，与混凝土适应性好，使用安全环保。
