Example Embodiment

[0051] In a second aspect of the present invention, there is provided a preparation method of the above-mentioned highly hydrophobic fluorocarbon composition. The preparation method includes: adding a dispersant to butyl acetate and stirring uniformly, adding a filler and an inorganic flame retardant to it and dispersing , Prepare filler dispersion;

[0052] Blending and grinding the filler dispersion with the fluorocarbon resin, and the mixture is sieved to obtain coating component A;

[0053] Mix and stir the coating component A with the curing agent.

[0054] Wherein, the mass ratio of the dispersant to butyl acetate is 1:200 to 800, and the stirring treatment time of the dispersant and butyl acetate is 5 to 20 minutes;

[0055] In order to enhance the uniformity of dispersion, after adding reinforcing filler and inorganic flame retardant, the dispersion is carried out by shearing ultrasonic dispersion, and the processing time is 20-60min;

[0056] Blending the filler dispersion wit...

Abstract

The invention provides a high-hydrophobicity fluorocarbon composition as well as a preparation method and application thereof, and belongs to the technical field of polymer insulating materials. The high-hydrophobicity fluorocarbon composition is prepared from the following raw materials in parts by weight: 60 parts of fluorocarbon resin; 10 to 25 parts of a reinforcing filler; 50 to 100 parts ofan inorganic flame retardant; 0.2-1 part of a dispersing agent; 12-20 parts of curing agent. The composition can resist electric corrosion and high-temperature damage caused by the electric corrosion,has high hydrophobicity, excellent tracking resistance and flame retardance compared with common silicone rubber coating, and can expand the application field of fluorocarbon coating in the aspect ofelectrical equipment insulation, so that the high-hydrophobicity fluorocarbon composition has a good practical application value.

Description

technical field [0001] The invention belongs to the technical field of polymer insulating materials, and in particular relates to a highly hydrophobic fluorocarbon composition and its preparation method and application. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Compared with traditional inorganic insulating materials such as glass and ceramics, polymer insulating materials have gradually become an insulating material that has attracted much attention due to their light weight, low cost, good mechanical properties, and hydrophobic and antifouling properties. Polymer insulating materials inevitably bear the comprehensive effects of various factors such as temperature ...
