Nano mortar coating with heat preservation function
The invention discloses a nano mortar coating with a heat preservation function. The mortar of the coating comprises the following raw materials in parts by weight: 400-450 parts of cement, 80-100 parts of a nano material, 30-50 parts of resin rubber powder, 1000-1500 parts of sand, 20-40 parts of fly ash, 20-40 parts of clay, 5-8 parts of carbon fibers and 7-10 parts of an additive. Nano materials (nano beads, nano TiO2 and nano ZnO2) are added, the nano materials are small in particle and easy to smear uniformly, the heat conductivity coefficient of the nano materials can reach 0.07 W/m.K orbelow, and the nano materials have good heat preservation and insulation performance; after resin rubber powder is added and mixed with cement and other thermal insulation mortar components, active components of the rubber powder are enriched on an interface layer of a thermal insulation board and mortar under the action of polarity, and the active components of the rubber powder begin to reach the action concentration along with outward continuous diffusion of moisture and are diffused on the interface layer to form an interpenetrating net-shaped structure, so that the the purpose of heat preservation is achieved; by adding the additive, the water-retaining property, sagging resistance and thixotropic deformation of the mortar are further improved, and the purpose of improving the performance of the coating is achieved.
一种具有保温功能纳米砂浆涂层，该涂层的砂浆原料组成按照重量配比包括：水泥400‑450份、纳米材料80‑100份、树脂胶粉30‑50份、砂1000‑1500份、粉煤灰20‑40份、粘土20‑40份、碳纤维5‑8份、添加剂7‑10份。本发明添加了纳米材料（纳米微珠、纳米TiO2和纳米ZnO2），纳米材料颗粒小，容易涂抹均匀，其导热系数可以达到0.07W/m.K以下，具有很好的保温隔热性能；添加了树脂胶粉，树脂胶粉与水泥等保温砂浆组成成分混合后，胶粉的活性成分在极性作用下富集在保温板、砂浆的界面层，随着水分的向外不断扩散，胶粉有效成分开始达到作用浓度，并在界面层扩散形成了相互穿透的网状结构，达到了保温的目的；通过添加添加剂，进一步改善砂浆的保水性、抗流挂性和触变形，达到提高涂层性能的目的。
