Environment-friendly color-difference-free facing mortar and preparation method thereof
The invention discloses environment-friendly color difference-free facing mortar and a preparation method thereof. The facing mortar is prepared from the following components: cement, aggregate, a water reducing agent, inert filler, an alkali efflorescence resisting agent, pigment and water. Wherein the saltpetering-resistant agent is a mixture of modified redispersible latex powder and modified graphene oxide, the prepared modified redispersible latex powder has good film forming and bonding capacity, meanwhile, the mechanical strength and compactness of cement hardened slurry can be improved, and when the modified redispersible latex powder and the modified graphene oxide are used in a mixed mode, the saltpetering-resistant effect is achieved. Through the template nucleation effect of the modified graphene oxide and the chelation on metal ions, the mortar has good saltpetering resistance and mechanical properties, and no volatile organic compounds are released in the use process of the mortar, so that the effects of environmental protection and no color difference are achieved.
本发明公开了一种环保无色差的饰面砂浆及其制备方法，该饰面砂浆包括以下组分：水泥、骨料、减水剂、惰性填料、抗泛碱剂、颜料、水。其中抗泛碱剂为改性可再分散乳胶粉和改性氧化石墨烯的混合物，本发明制备的改性可再分散乳胶粉具有良好的成膜、粘结能力，同时可以提高水泥硬化浆体的力学强度和致密性，且与改性氧化石墨烯混合使用，通过改性氧化石墨烯的模板成核效应以及对金属离子的螯合作用，使得砂浆具有良好的抗泛碱性能以及力学性能，且砂浆在使用过程中无挥发性有机物的释放，从而达到环保无色差的效果。
