Polyether-based maleimide copolymer and application thereof in concrete additive
The invention discloses a polyether-based maleimide copolymer. The polyether-based maleimide copolymer is characterized in that the polyether-based maleimide copolymer is prepared from polyethylene glycol monoallyl ether, furo [3, 4-d]-1, 3-dioxolane-2, 4, 6-trione, 4, 4 '-diaminostilbene-2, 2'-disulfonic acid and maleimide-tri (ethylene glycol)-propionic acid through free radical polymerization.The concrete additive prepared from the polyether-based maleimide copolymer can improve the strength, durability and thawing and freezing resistance of concrete, is small in mixing amount and remarkable in plasticizing effect, can obviously increase the slump of the concrete, and is good in adaptability to the concrete.
本发明公开了一种聚醚基马来酰亚胺类共聚物，其特征在于，所述聚醚基马来酰亚胺类共聚物是由聚乙二醇单烯丙基醚、呋喃并[3,4‑d]‑1,3‑二氧杂环戊烯‑2,4,6‑三酮、4,4'‑二氨基二苯乙烯‑2,2'‑二磺酸、马来酰亚胺‑三(乙烯乙二醇)‑丙酸通过自由基聚合制备得到。由本发明的聚醚基马来酰亚胺类共聚物制成的混凝土添加剂能够提高混凝土的强度、耐久性和抗融冻性，掺量少、增塑效果显著、可明显增大混凝土的坍落度，且与混凝土适应性好。
