Embodiment 1
[0026] A kind of preparation technology of nanodiamondene, its step is:
[0027] (1) Preliminary crushing: the diamond raw material is sent into the ball mill shaping barrel, after the ball mill crushing and shaping process of steel balls of different sizes under high-speed rotation, it is carried out through a screen with a certain mesh number at the receiving port of the ball mill. Collection, the mesh number of the sieve is not less than 70 mesh, and the ball milling time is generally controlled within 1 to 5 hours. The 70 mesh coarse material is automatically returned to the ball mill for ball milling and reshaping; the collected particles above 70 mesh are passed through a multi-layer vibrating screen machine. The particle size is first classified, and the mesh number of the sieve is arranged from high to low from 100 mesh to 800 mesh. The time of vibrating the sieve is generally 30 minutes to 2 hours. Finally, the fine material filtered by the 800 mesh sieve is collected,...
Embodiment 2
[0035]A diamondene reinforced and toughened PA6 modified plastic is made of the following raw materials in parts by weight: 85 parts of nylon chips, 10 parts of nanodiamondene, and 1.5 parts of calcium stearate. The preparation method of nanodiamondene is the same as in Example 1.
[0036] Nanodiamondene is subjected to the following surface functionalization treatment: adding nanodiamondene to ethanol, ultrasonically dispersing for 1 hour, adding hydrolyzed titanate coupling agent, stirring and reacting at 50°C for 22 hours, and drying by centrifugation; the nanodiamondene The dosage ratio of alkene to ethanol is 0.8g:50ml, and the addition amount of titanate coupling agent is 3.0% of that of nanodiamondene.
[0037] The preparation method of the above-mentioned diamondene reinforced and toughened PA6 modified plastics comprises the following steps: 1) Weigh and mix the raw materials in proportion to obtain a mixture; 2) Melt extrusion: send the mixture into a twin-screw extr...
Embodiment 3
[0039] A diamondene reinforced and toughened PA6 modified plastic is made of the following raw materials in parts by weight: 95 parts of nylon chips, 5 parts of nanodiamondene, and 0.5 part of stearic acid. The preparation method of nanodiamondene is the same as in Example 1.
[0040] The nano-diamantene is subjected to the following surface functionalization treatment: adding the nano-diamantene to ethanol, ultrasonically dispersing for 0.5 h, adding the hydrolyzed titanate coupling agent, stirring and reacting at 40°C for 20 h, and drying by centrifugation; The dosage ratio of nanodiamantene and ethanol is 0.5g:50ml, and the addition amount of titanate coupling agent is 1.0% of nanodiamantene.
[0041] The preparation method of the diamondene-reinforced and toughened PA6 modified plastic comprises the following steps: 1) Weigh and mix the raw materials in proportion to obtain a mixture; 2) Melt extrusion: send the mixture into a twin-screw extruder Carry out melt extrusion,...
