preparation example Construction

[0030] The preparation method of high-performance calcium carbonate for the stone slab comprises the following steps:

[0031] S1: Select marble, limestone, etc. transported from the material field to clean and remove impurities, dry the stone to remove surface moisture, and then use a crusher to crush the stone to obtain calcium carbonate fragments;

[0032] S2: transporting the broken calcium carbonate obtained in step S1 into a vertical mill and synchronously adding grinding aids and grinding to obtain calcium carbonate fine stone powder;

[0033] S3: classifying the calcium carbonate fine stone powder prepared in step S2 with a classifier to obtain calcium carbonate powder of 400-600 mesh;

[0034] S4: Add the calcium carbonate powder obtained in step S3 into a high-speed mixer, then add sodium dioctyl succinic acid sulfonate, stannous chloride, and magnesium oxide, raise the temperature to 92-103°C, and heat at 1100-1300r / Stir at a high speed of 24-28min at a speed of 2...

Abstract

The invention discloses high-performance calcium carbonate used for stone slabs and a preparation method of the high-performance calcium carbonate. The high-performance calcium carbonate used for stone slabs comprises the following raw materials: a calcium carbonate crushed matter, a grinding aid, dioctyl succinic acid sodium sulfonate, stannous chloride, magnesium oxide, pentasodium DTPA, a modifier, 3-aminopropyltriethoxysilane, bis(2-ethylhexyl) phthalate, modified polyacrylate, ethylene bis(stearamide), 2-(2'-3-hydroxy-3',5'-di-tert-phenyl)-5-benzotriazole chloride, polyacrylamide and a stabilizer. The high-performance calcium carbonate is prepared according to the steps of stone slab cleaning, impurity removal, water removal, crushing, grinding, surface modification, performance adjustment, smashing, drying and the like. The high-performance calcium carbonate used for stone slabs is added into the stone slabs, little agglomeration occurs, the dispersibility is good, and the mechanical properties are obviously improved.

Description

【Technical field】 [0001] The invention belongs to the technical field of preparation of modified calcium carbonate, and in particular relates to a high-performance calcium carbonate for stone plates and a preparation method thereof. 【Background technique】 [0002] As the latest artificial building material, artificial quartz stone has incomparable advantages of natural stone such as high strength, high hardness, high temperature resistance, corrosion resistance, anti-aging, easy cleaning, wear resistance, pure material, and no radiation. Today, as natural stone is being exhausted as a non-renewable resource, artificial quartz stone is the best substitute. At the same time, artificial quartz stone can use waste glass as raw material, thus realizing resource reuse while protecting the environment. These advantages make Artificial quartz stone has become an upstart in the architectural decoration industry, and is widely used in cabinets, bathrooms, floors and wall decorations i...
