Abstract

The invention discloses a preparation method of a terrazzo polishing powder. The preparation method is characterized in that the Al2O3 (aluminum oxide)-SiO2 (silicon dioxide)-Fe2O3 (ferric oxide) compound is used as a grinding material, oxalic acid is used as an acid polishing agent, and a dispersant, a surfactant and the like are used as additives, so as to prepare the polishing powder. The preparation method specifically comprises the following steps of adding the following components into a reactor, such as 50 to 58% of water, and 4 to 8% of ferric trichloride; after stirring and dissolving, adding 22 to 28% of aluminum oxide, and 10 to 15% of silicon dioxide, and adding 3 to 6% of ammonia water, wherein the sum of the components is 100%; stirring to react for 30min at room temperature, separating solid and liquid, drying at the temperature of 105+ / -2 DEG C, roasting for 2h at the temperature of 500+ / -10 DEG C, cooling, and crushing by air flow, so as to obtain the Al2O3-SiO2-Fe2O3 compound. The polishing powder has the advantages that the polishing effect is good, the glossiness is high, the number of scratches is fewer, the flatness is high, and the usage amount is small.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to a preparation method of terrazzo polishing powder. Background technique [0002] Terrazzo (also known as terrazzo) is a product made by mixing gravel, glass, quartz stone and other aggregates into cement binder to make a concrete product, and then grinding and polishing the surface. The terrazzo made of cement binder is called inorganic terrazzo, and the terrazzo made of epoxy binder is also called epoxy terrazzo or organic terrazzo. According to the construction process, terrazzo is divided into on-site pouring terrazzo and prefabricated plate terrazzo floor . Traditional terrazzo has a huge market in China due to its unique advantages such as low cost, optional color mosaic, and convenient construction. There are as many as one billion square meters of terrazzo floors used in various buildings in urban and rural areas across the country. Abrasion-resistant terrazzo, the surface ...
