Interface agent for plastering mortar and wall surface treatment process before and after plastering mortar construction
The invention discloses an interface agent for plastering mortar and a wall surface treatment process before and after plastering mortar construction. The interface agent for plastering mortar is prepared from the following raw materials in percentage by weight: 30 to 50 weight percent of cement, 2 to 4 weight percent of silica fume, 23 to 28 weight percent of limestone powder, 25 to 35 weight percent of fine sand, 0.08 to 0.12 weight percent of water-retaining thickening agent, 1.4 to 1.8 weight percent of polymer latex powder, 0.003 to 0.005 weight percent of internal curing agent and 0.03 to 0.06 weight percent of hollow fiber. By means of the internal curing agent and the hollow fibers in the interface agent, the problems that the water demand is increased, plastic cracking occurs, the strength is reduced and powder falls off due to the fact that only the internal curing agent is added into plastering mortar are solved; according to the process, the defect of wall plastering cracking can be thoroughly overcome, the bonding force between the base face and plastering mortar is further increased through the hollow fibers, and the defect of plastering mortar hollowing is overcome.
本发明公开了一种抹灰砂浆用界面剂及抹灰砂浆施工前后墙面处理工艺。该抹灰砂浆用界面剂，按重量百分比计，其原料包括：水泥30‑50wt％、硅灰2‑4wt％、石灰石粉23‑28wt％、细砂25‑35wt％、保水增稠剂0.08‑0.12wt％、聚合物乳胶粉1.4‑1.8wt％、内养护剂0.003‑0.005wt％、中空纤维0.03‑0.06wt％。本发明通过界面剂中的内养护剂以及中空纤维，避免了仅在抹灰砂浆中加入内养护剂导致需水量变大，出现塑性开裂、强度降低、掉粉的问题；本发明的工艺能够彻底解决墙面抹灰开裂的弊端，中空纤维还增加了基面与抹灰砂浆的粘接力，解决了抹灰砂浆空鼓的弊端。
