Environment-friendly anti-cracking dry-mixed mortar and preparation method thereof
The invention discloses environment-friendly anti-cracking dry-mixed mortar and a preparation method thereof, and relates to the technical field of building materials. The preparation method comprisesthe following steps: firstly, coating bamboo fibers with aniline, then, putting the coated bamboo fibers into a polyurethane emulsion, preparing modified bamboo fibers through a reaction under the action of an initiator, carrying out a reaction process on coconut fibers, acrylic acid and acrylamide to prepare modified coconut fibers, adding the modified coconut fibers and the modified bamboo fibers into cement, adding water, stone powder and fly ash, and stirring and mixing to obtain the environment-friendly anti-cracking dry-mixed mortar. The prepared environment-friendly anti-cracking dry-mixed mortar has excellent anti-cracking performances, and the added modified bamboo fibers and modified coconut fibers cause little pollution to the environment.
本发明公开了一种环保型抗开裂干粉砂浆及其制备方法，涉及建筑材料技术领域。本发明先用苯胺对竹纤维进行包覆，然后将报复后的竹纤维置于聚氨酯乳液中，在引发剂的作用下反应，制得改性竹纤维，然后，将椰纤维与丙烯酸和丙烯酰胺共同反应，制得改性椰纤维，最后将改性椰纤维与改性竹纤维加入水泥中，并加入水，石粉和粉煤灰，搅拌混合，得环保型抗开裂干粉砂浆。本发明制备的环保型抗开裂干粉砂浆具有优异的抗开裂性能，且加入的改性竹纤维和改性椰纤维对环境污染较小。
