Abstract

Disclosed is a method of forming a composite micropowder, including mixing 100 parts by weight of fluorine-containing polymer, 10 to 140 parts by weight of silane, catalyst, and water, such that the silane is in-situ polymerized in the fluorine-containing polymer to form a polysiloxane, and the fluorine-containing polymer and the polysiloxane form a composite. The composite is dried, and then physically crushed to form composite micropowder. The total weight of the fluorine-containing polymer and the silane and the weight of the catalyst have a ratio of 100:0.1 to 100:0.0001. The silane and the water have a molar ratio of 1:0.5 to 1:3. The composite micropowder has a diameter of 0.1 [mu]m to 15 [mu]m. The fluorine-containing polymer and the polysiloxane in the composite micropowder have a weight ratio of 95:5 to 60:40. The composite micropowder has excellent non-sticky property, manufactured in a simple way, safe, environmentally-friendly and low in cost.

Description

technical field

[0001] The invention provides a composite material micropowder of a fluorine-containing polymer, and particularly relates to its preparation method and application. Background technique

[0002] Fluoropolymers, especially polytetrafluoroethylene, have the highest chemical inertness among all polymers, and have unique properties such as weather resistance, electrical insulation, low friction coefficient, and chemical resistance, and have been widely used in aviation, automobiles, etc. , petroleum and chemical industries. Fluoropolymer micropowder, especially polytetrafluoroethylene (PTFE) micropowder, has a fine and soft particle size, good dispersion ability, and can be evenly dispersed in other substrates, thereby changing the properties of other substrates (such as improving lubrication) properties, improve wear resistance, enhance scratch resistance, increase release properties, impart stain resistance, improve flame retardancy, and increase water repelle...
