example 1

[0080] Aluminate surface-modified microcrystalline muscovite active filler (600 mesh) and a preparation method thereof. The microcrystalline muscovite powder sample used in this example is produced from a very large microcrystalline muscovite deposit in a certain place in Sichuan. As mentioned above, the deposit was first discovered in 1997 by the applicant of the patent, Chengdu University of Technology. Over the past few years, Sichuan Xinju Mining Resources Development Co., Ltd. and Chengdu University of Technology have done some work on the type, chemical composition, mineral composition, structure and beneficiation experiments of Sichuan microcrystalline muscovite ore, and successfully developed it accordingly. Xinju brand microcrystalline muscovite powder series products with different particle sizes such as 200 mesh, 325 mesh, 400 mesh, 600 mesh, 800 mesh, 1250 mesh and 2500 mesh have been launched. The microcrystalline muscovite samples of all examples in this patent ...

Abstract

The invention discloses a microcrystalline muscovite active powder filler modified on the surface of an aluminate coupling agent and a preparation method thereof. The microcrystalline muscovite powder is used as a raw material. The muscovite powder material is dried at about 110 °C to remove all adsorbed moisture; melt the aluminate (for wax-like solids), and melt the aluminate at a temperature slightly higher than the melting point of 70 to 73 °C; Dry the material and put it into a high-speed mixer; preheat the material, make the material stir at a high speed in the high-speed mixer for about 30 minutes, and control the temperature to be ≤73°C; weigh the aluminate, and the weight is based on material: aluminate = 100:0.5 ~3.9; high-speed mixing of materials, slowly and evenly pour the aluminate into the high-speed mixer, high-speed mixing for about 20 minutes, and control the temperature to be ≤90 °C; modification effect testing, using viscosity testing and other methods to test and evaluate the modification effect. Evaluation. It has abundant resources, convenient modification process, low cost, good effect, wide application and obvious economic and social benefits.
