Preparation method of self-cleaning wear-resistant functional material
The invention discloses a preparation method of a self-cleaning wear-resistant functional material. The preparation method comprises the following four steps: diatomite activation, primary crushing, secondary crushing of mixed materials, and mixing and stirring. A sodium carbonate solution is used for diatomite activation, so that acidic organic matters and ionic impurities in the diatomite can beremoved, the whiteness and bulk density of the diatomite are improved; and high-temperature activation greatly reduces the content of oxide impurities and increases the specific surface area and thepore volume. The self-cleaning wear-resistant functional material is smeared on the outer wall of a building and is naturally aired; the diatomite has high specific surface area, pore volume and bulkdensity, so a large amount of water is can efficiently absorbed and released, the wall surface humidity is adjusted, and harmful gases such as free formaldehyde, benzene, toluene and the like in the air are adsorbed; and the Portland fly ash cement and a sepiolite fabric improve the strength and the wear resistance of the material, further improve the adsorption performance and the self-cleaning purification performance of the material due to the good crushing uniformity, and prolong the service life of the outer wall.
本发明公开一种自清洁耐磨功能材料的制备方法，包括硅藻土活化、一次粉碎、混料二次粉碎、混合搅拌四个步骤；其中，硅藻土活化使用碳酸钠溶液能够去除硅藻土中的酸性有机物和离子杂质，提高硅藻土的白度和堆密度，高温活化大大降低了氧化物杂质含量，增加了比表面积和孔容积。将本自清洁耐磨功能材料涂抹在建筑外墙自然晾干后，由于硅藻土的高比表面积、孔容积、堆积密度，能够高效大量地吸收水分和释放水分，调节墙面湿度，吸附空气中的游离甲醛、苯、甲苯等有害气体，粉煤灰硅酸盐水泥、海泡石绒提高材料强度、耐磨性的同时，由于粉碎均匀性好，进一步提高了材料的吸附性能、自清洁净化性能和外墙使用寿命。
