Description

technical field [0001] The invention relates to the technical field of new materials, and in particular to a method for preparing a hydrophobic dispersion material. Background technique [0002] Hydrophobic solid powders are more and more widely used in the fields of thermal insulation materials, coatings and surface treatment that require lotus leaf hydrophobic effect on the surface. Due to its strong hydrophobic effect, hydrophobic solid powder is completely incompatible with water and cannot be dispersed in water. It needs to use a solvent to get a good dispersion. Only a well-dispersed hydrophobic solid powder has practical application value. However, the introduction of solvents has caused the volatile organic compounds (VOC) of the material to exceed the standard, and the volatile organic compounds are lost in the air, causing pollution to the environment and endangering the health of people, animals and plants. Today, with increasingly stringent environmental protect...
