[0034] A preparation method of solid buoyancy material for abyss development equipment, comprising the following steps:
[0035] 1), weigh each component according to the required number of copies;
[0036] 2), add the carbon nanofibers weighed in step 1) into the mixed solution of concentrated sulfuric acid and concentrated nitric acid, stir mechanically for 2h at a low speed (rotation speed≤20rpm / min) in a 65°C water bath heating environment, and then ultrasonically disperse for 30min, then filter, remove Washing and drying with ionized water to obtain surface-treated carbon nanofibers, which are for later use;
[0037] 3), the matrix resin and the carbon nanofibers after the surface treatment in step 2) are evenly mixed and ultrasonically dispersed to obtain a resin glue, which is for subsequent use;
[0038] 4) Mix the curing agent, accelerator, polyol, hollow glass beads and the resin glue prepared in step 3) in a mixer at a low speed (rotation speed: 5-15 rpm / min), and ...
Embodiment 1
[0042] A solid buoyancy material for abyss development equipment is made of 100 parts of matrix resin, 90 parts of curing agent, 1 part of accelerator, 3 parts of polyol, 0.5 parts of nano carbon fiber and 85 parts of hollow glass microspheres according to the parts by mass. Wherein, the matrix resin selects 3,4-epoxy-6-methylcyclohexanecarboxylic acid-3',4'-epoxy-6'-methylcyclohexylmethyl, and the curing agent selects methyltetrahydro-o-phenylene Diformic anhydride MeTHPA, stannous octoate as the accelerator, glycerol as the polyol, 150-200 nm in diameter and 10-50 μm in length of the carbon nanofibers, and S32 from 3M company for hollow glass beads.
[0043] The preparation method of the solid buoyancy material is:
[0044] 1), weigh each component according to the required number of copies;
[0045] 2), adding the carbon nanofibers weighed in step 1) into the mixed solution of concentrated sulfuric acid and concentrated nitric acid, mechanically stirring at 20rpm / min for 2...
Embodiment 2
[0053] A solid buoyancy material for abyss development equipment is made of 100 parts of matrix resin, 180 parts of curing agent, 2 parts of accelerator, 2 parts of polyol, 1 part of nano carbon fiber and 160 parts of hollow glass microspheres according to the parts by mass. Wherein, the matrix resin selects vinylcyclohexene, the curing agent selects methylhexahydrophthalic anhydride MeHHPA, the accelerator selects benzyldimethylamine, the polyol selects ethylene glycol, and the nanocarbon fiber diameter is 100-150nm , the length is 10-50μm, and the hollow glass microbeads are HK38 from Zhengzhou Sunlight Hollow Glass Microbeads New Material Co., Ltd.
[0054] The difference between the preparation method of Example 2 and Example 1 is: in step 5), first radiate continuously for 10 min with a microwave power of 150w, and then radiate continuously for 10min with a microwave power of 300w; the blank obtained in step 6) is heated to 160°C and kept for 2h.
