The invention has good stability, and high surface activity.

Description

technical field [0001] The invention relates to a silicon fluoropolymer, in particular to a new water-based silicon fluoropolymer, and also to a preparation method of the polymer, and further to an aqueous dispersion of the polymer. Background technique [0002] Organosilicon polymers refer to high molecular compounds formed by the polymerization of silicon-containing organic compounds under certain conditions. As well as superior physical and mechanical properties at high temperatures, self-extinguishing properties, etc., but it also has disadvantages such as adhesion, wear resistance, oil resistance, and poor solvent resistance. [0003] Organic fluoropolymers refer to high molecular compounds formed by polymerizing fluorine-containing organic compounds under certain conditions. It has excellent weather resistance, durability, chemical resistance and corrosion resistance, wear resistance, insulation, non-adhesion and pollution resistance, etc. Its shortcomings are mainly ...
