Problems solved by technology

[0011] 1. The particle size is not fine enough and the distribution is wide
For example, the particle size distribution range of tourmaline produced by CN1287888A disclosed "tourmaline and its manufacturing method" is 0.1-15 μm, and no specific d 50 、d 90 、d 97 Data with equal particle size and particle size distribution is difficult to meet user requirements
[0012] 2. Without surface treatment
Since tourmaline is an inorganic mineral material, without surface treatment or surface modification, when it is directly used in organic base materials such as chemical fibers, the compatibility and dispersion are poor, which affects the mechanical properties of the product; in addition, ultrafine tourmaline powder Large specific surface area and high surface energy, without proper surface treatment, it is easy to form agglomeration and affect its final use performance

The invention realizes super fine grain size, better dispersity and surface activity.

Description

Technical field: [0001] The invention relates to a preparation method of ultrafine tourmaline powder material. Background technique: [0002] Tourmaline is a silicate mineral with a ring structure of aluminum, sodium, iron and lithium characterized by boron, and its chemical formula can be abbreviated as NaR 3 Al 6 Si 6 B 3 o 27 (OH) 4 , where Na can be locally replaced by K and Ca, (OH) can be replaced by F, but there is no phenomenon of Al replacing Si. The R position is homogeneous and heterogeneous, and there are mainly four terminal members: [0003] R=Mg Magnesite, NaMg 3 Al 6 [Si 6 o 18 ][BO 3 ] 3 (OH) 4 ; [0004] R=Fe black tourmaline, NaFe 3 Al 6 [Si 6 o 18 ][BO 3 ] 3 (OH) 4 ; [0005] R=Li+Al lithium tourmaline, Na(Li, Al) 3 Al 6 [Si 6 o 18 ][BO 3 ] 3 (OH,F) 4 ; [0006] R=Mn sodium manganese tourmaline, NaMn 3 Al 6 [Si 6 o 18 ][BO 3 ] 3 (OH) 4 ; [0007] The shape of tourmaline is compound trigonal single cone crystal, the cr...
