Anti-cracking micro cement decorative material
The invention discloses an anti-cracking micro-cement decorative material, which is composed of the following components: Portland cement, quartz powder, silica fume, precipitated silica, redispersible latex powder, a polycarboxylic acid superplasticizer, a special coagulant, special fibers and water. The special coagulant and three specific fibers are added into the formula, so that the setting time of the micro cement can be shortened, the early water loss can be effectively reduced, the risk of generating plastic cracks can be reduced, and the action of capillary tension of the micro cement can be reduced, thereby effectively reducing the drying shrinkage of the micro cement and reducing the corresponding cracking risk; three specific fibers with limited quantity are adopted, so that the tension crack resistance of the micro-cement is improved, cracking types are effectively resisted, and the defect that all types of cracks cannot be resisted at the same time by adopting a traditional fiber using method is overcome.
本发明公开了一种抗开裂微水泥装饰材料，它由以下组份组成：硅酸盐水泥、石英粉、硅灰、沉淀二氧化硅、可再分散乳胶粉、聚羧酸高效减水剂、特种促凝剂、特种纤维和水。本发明通过在配方中加入特种促凝剂及三种特定纤维，不但可以缩短微水泥的凝固时间，有效减少早期水分损失，降低产生塑性裂纹的风险，还能降低微水泥毛细管张力的作用，从而有效减少微水泥的干燥收缩及降低相应的开裂风险；采用限定量的三种特定纤维，增加微水泥的抗拉裂能力，有效抵抗开裂类型，克服了传统纤维使用方法无法同时抵抗所有类型的开裂的缺点。
