Production process of rigid polymer fiber for concrete crack resistance
The invention relates to the technical field of rigid polymer fibers, in particular to a production process of rigid polymer fibers for concrete crack resistance. The rigid polymer fiber comprises the following raw materials: polypropylene, a blended resin, a filling agent, a fiber material and anti-cracking powder. In the production process of the rigid polymer fiber for concrete crack resistance, the added blended resin is selected from high-density polyethylene, and is blended with polypropylene so as to improve the rigidity of polypropylene; the added filling agent can improve the rigidity of polypropylene to a certain extent through filling modification while the toughness is enhanced; the crack resistance of the finished product fiber can be improved by coating the anti-cracking powder on the surface of the prepared polymer fiber; and when the anti-cracking powder is added into concrete to be stirred, the anti-cracking powder can be separated from the surface of the polymer fiber to be blended with the concrete, so that the crack resistance of the concrete is improved.
本发明涉及刚性聚合纤维技术领域，具体地说，涉及一种用于混凝土抗裂的刚性聚合纤维生产工艺。其包括以下原料组成：聚丙烯、共混树脂、填充剂、纤维材料和抗裂粉剂，该用于混凝土抗裂的刚性聚合纤维生产工艺中，加入的共混树脂选自高密度聚乙烯，通过与聚丙烯共混可提升聚丙烯的刚性，加入的填充剂，通过填充改性可在一定程度上改善聚丙烯的刚性，同时增强了韧性，通过在制备后的聚合纤维表面涂抹抗裂粉剂，可提高成品纤维的抗裂性，当加入至混凝土中进行搅拌时，可脱离聚合纤维表面与混凝土共混，从而增加了混凝土的抗裂性。
