Plastering mortar not easy to crack and fall off and preparation method thereof
The invention relates to the technical field of plastering mortar, and discloses plastering mortar difficult to crack and fall off and a preparation method thereof, the plastering mortar comprises cement, slaked lime, ardealite, sand, a novel anti-cracking agent, a thickening agent and an auxiliary agent; the weight of the thickening agent accounts for 0.3%-1.4% of the total weight of the raw materials; the weight of the sand accounts for 60-82% of the total weight of the raw materials; the cohesive force of the plastering mortar and the bonding force to a machine body are improved, the strength of the plastering mortar is improved, the adopted lignocellulose can play a role in guiding water, when water on the surface of the plastering mortar evaporates too much, the internal water can be guided out, the surface of the plastering mortar is not prone to cracking, and the plastering mortar has a good waterproof effect. The thixotropic agent improves the workability and cohesiveness of the plastering mortar, and meanwhile, the novel anti-cracking agent poly (p-phenylene benzobisoxazole) fiber is adopted, so that the water loss rate of the plastering mortar is further reduced, the crack resistance of the plastering mortar is improved, and the plastering mortar has good heat preservation performance.
本发明涉及抹灰砂浆技术领域，公开了一种不易开裂脱落的抹灰砂浆及其制备方法，包括水泥、熟石灰、磷石膏、砂、新式抗裂剂、增稠剂和助剂；所述增稠剂的重量占原料总重量的0.3％～1.4％；所述砂的重量占原料总重量的60％～82％；本发明提高了抹灰砂浆的内聚力和对机体的粘接力，增加了抹灰砂浆的强度，而采用的木质纤维素能够起到导水作用，当抹灰砂浆表面水分蒸发较多时，能够将内部的水导出，使抹灰砂浆的表面不易开裂，并且触变剂在提高抹灰砂浆工作性和粘聚性的同时，通过采用新式抗裂剂聚对苯撑苯并双噁唑纤维，进一步降低了抹灰砂浆的失水速率，提高了抹灰砂浆的抗裂性，抹灰砂浆的抗裂性，并有较好的保温性。
