| titleOfInvention | Method for producing spherical or square powder filler, spherical or square powder filler obtained therefrom and application thereof |
| abstract | The present invention relates to a method for producing a spherical or rectangular powder filler. It includes the steps of providing a spherical or rectangular siloxane comprising T units; The spherical or rectangular siloxane is heat-treated to obtain a condensed siloxane by condensation reaction of silanol in the spherical or rectangular siloxane-the heat treatment temperature is 250 degrees or more to less than the organic group oxidation decomposition temperature; And treating the condensed siloxane by adding a treating agent to promote condensation of silanol in the condensed siloxane to obtain a spherical or prismatic powder filler-the treating agent includes a silane coupling agent and/or disilazane, and at least some silane The molecular weight of the coupling agent and/or disilazane is 210 or less divided by the specific gravity at 25 degrees. The present invention further provides a spherical or rectangular powder filler obtained through this. The present invention further provides the application of the spherical or rectangular powder filler. The filler provided by the present invention has low dielectric constant and dielectric loss, has no conductive foreign substances and coarse particles, and exhibits low radioactivity. |
