Recycled fiber reinforced fiber sulphoaluminate cement wallboard formula for wind power blade

CAO ZHENTAO / YUAN WEI / LIU CHAO

The invention discloses a wind power blade reuse fiber reinforced fiber sulphoaluminate cement wallboard formula, and relates to the technical field of fiber sulphoaluminate cement, the wind power blade reuse fiber reinforced fiber sulphoaluminate cement wallboard formula comprises mixed slurry, fiber and water, the mixed slurry comprises 1 part of 42.5 sulphoaluminate cement, 1 part of common river sand, 0.016 part of a polycarboxylate superplasticizer, 0.128 part of a pure acrylic polymer emulsion and 0.00128 part of a liquid defoaming agent, the size of the recycled fiber is one of A (1mm), B (2mm), C (3mm) and O (0.5 mm), the proportion of the fiber is 0-14%, and the proportion of water is 17-31%; according to the invention, the recycled fibers are added into the sulfur-aluminum cement-based material to prepare the mixed slurry, and cracking of the cement-based material can be delayed and microcrack propagation can be prevented by virtue of the crack resistance of the recycled fibers, so that the wallboard finished product is not easy to break during bending; the method has the advantages that the bending resistance of a final wallboard finished product is improved, meanwhile, the obsolete wind power blades can be recycled, and waste utilization is achieved.

本发明公开了风电叶片回用纤维增强纤维硫铝酸盐水泥墙板配方，涉及纤维硫铝酸盐水泥技术领域，所述风电叶片回用纤维增强纤维硫铝酸盐水泥墙板配方包括混合泥浆、纤维和水，所述混合泥浆包括1份42.5硫铝水泥、1份普通河砂、0.016份聚羧酸减水剂、0.128份纯丙聚合物乳液、0.00128份液体消泡剂，所述回收纤维的尺寸为A(1mm)、B(2mm)、C(3mm)和O(0.5mm)中的一种，纤维的比例为0‑14％，水的比例为17‑31％；本发明通过在硫铝水泥基材料中添加回收纤维制成混合泥浆，依靠回收纤维具有的阻裂性，能够延缓水泥基材料的开裂，并阻止微裂纹扩展，使墙板成品在弯曲时不容易断裂；具有提高最终墙板成品的抗弯性能，同时可以回收利用淘汰的风电叶片，实现废物利用的优点。
