Embodiment 1
[0029] The invention provides a modified polychlorotrifluoroethylene, which is made of polychlorotrifluoroethylene and a modifier, the modifier is graphite and carbon fiber, and the weight percentages of the components of the modified polychlorotrifluoroethylene are respectively Polytrifluorochloroethylene accounts for 88%; graphite accounts for 2%; carbon fiber accounts for 10%.
[0030] Choose short filamentary carbon fiber, its appearance is black powder, and its specific gravity is 1.7 grams per square centimeter. Carbon fiber (CF for short) is a new type of fiber material with high strength and high modulus fibers with a carbon content of more than 95%. It is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite microcrystals along the axial direction of the fiber, and undergoing carbonization and graphitization. Carbon fiber is "soft on the outside and rigid on the inside", lighter than metal aluminum, but stronger than steel, a...
Embodiment 2
[0044] The manufacturing process and method are the same as in Example 1, the graphite is changed to p-polyphenyl, the carbon fiber is changed to glass fiber, and the weight percentages of each component are respectively 70% for polychlorotrifluoroethylene; 20% for p-polyphenyl; and 20% for carbon fiber. 10%, polytrifluorochloroethylene, p-polyphenylene and carbon fiber were dried separately, and the drying temperature was 100°C; the density of the finished product was 1.9g / cm 3 .
Embodiment 3
[0046] The manufacturing process and method are the same as in Example 1, the graphite is changed into ceramic powder, the carbon fiber is changed into aluminum powder, and the weight percentages of each component are respectively polychlorotrifluoroethylene accounting for 80%; ceramic powder accounting for 10%; aluminum powder accounting for 10%; Dry polychlorotrifluoroethylene, ceramic powder and aluminum powder separately at a drying temperature of 100°C; the density of the finished product is 2.5g / cm 3 .
