Abstract

Official abstract text for this publication.

A manufacturing method of thermal paste is provided. The manufacturing method includes: providing a base material; heating a metal material to a liquid state, to generate a liquid metal material; sieving the liquid metal material to generate a metal powder material; adding a dispersant to the metal powder material and mixing to generate a mixed powder material; and mixing the mixed powder material and the base material.

First claim

Opening claim text (preview).

What is claimed is: 1 . A manufacturing method of thermal paste, comprising: providing a base material; heating a metal material to a liquid state, to generate a liquid metal material; sieving the liquid metal material and cooling the sieved liquid metal material to generate a metal powder material; adding a dispersant to the metal powder material and mixing to generate a mixed powder material; and mixing the mixed powder material and the base material; wherein the dispersant comprises a layered silicate clay material and a fluororesin material; wherein the base material is composed of a silicone material, a thermally conductive particle material and a solvent; wherein the thermally conductive particle material is selected from a group composed of aluminum nitride, boron nitride, aluminum oxide, and copper oxide; wherein the metal material is selected from a group composed of a gallium indium tin alloy material, an indium tin alloy material, a gallium aluminum alloy material, a gallium bismuth alloy material, a gallium tin alloy material and a gallium indium alloy material. 2 . The manufacturing method of thermal paste according to claim 1 , wherein the step of sieving the liquid metal material is using a screen to sieve the liquid metal material, a mesh of the screen ranges from 300 to 1000. 3 . The manufacturing method of thermal paste according to claim 1 , wherein before the step of adding the dispersant to the metal powder material and mixing, the manufacturing method further comprises performing a surface plasma treatment on the metal powder material. 4 . The manufacturing method of thermal paste according to claim 1 , wherein the step of adding the dispersant to the metal powder material and mixing comprises grinding and mixing the metal powder material and the layered silicate clay material. 5 . The manufacturing method of thermal paste according to claim 1 , wherein the step of mixing the mixed powder material and the base material comprises grinding and mixing the mixed powder material and the base material.
