Embodiment 1
[0058] Radiation resistance material raw materials (parts by weight): 15 parts of modified tourmaline, 10 parts of nano-silver, 10 parts of aluminum oxide, 5 parts of zinc ferrite, 2 parts of dispersant, 5 parts of epoxy resin, 0.2 part of diethylenetriamine, 50 parts of ethanol.
[0059] The dispersant is isopropyl myristate.
[0060] The preparation method of the radiation protection necklace comprises the following steps:
[0061] (1) Degreasing: Soak the stainless steel necklace substrate in 85°C degreasing agent for 15 minutes, take it out and wash it with deionized water for later use. The degreasing agent includes the following components: sodium hydroxide 80g / L, sodium carbonate 40g / L, the balance is deionized water;
[0062] (2) Pickling: Soak the stainless steel necklace substrate treated in step (1) in a mixed acid solution at 40°C for 30 seconds, take it out and wash it with deionized water for later use. The mixed acid solution includes the following components:...
Embodiment 2
[0070] It is basically the same as Example 1, the only difference is:
[0071] The preparation method of described modified tourmaline comprises the following steps:
[0072] (1) Mix tourmaline and acid solution according to the solid-to-liquid ratio of 1g: 10mL, stir at 40°C at 200 rpm for 3 hours, perform suction filtration at a vacuum of 0.05MPa, and wash the obtained solid with deionized water until the eluate It is neutral, and the solid is dried at 85°C for 8 hours to obtain acidified tourmaline; the acid solution is a mixed solution of hydrochloric acid aqueous solution and ascorbic acid aqueous solution at a volume ratio of 9:1, wherein the mass fraction of hydrochloric acid aqueous solution is 20%, and the mass fraction of ascorbic acid aqueous solution is The quality score is 20%;
[0073] (2) Sodium stearate and ethanol are mixed uniformly according to the solid-to-liquid ratio of 1g: 100mL to obtain a sodium stearate ethanol solution, then acidified tourmaline is ...
Embodiment 3
[0075] It is basically the same as Example 1, the only difference is:
[0076] The preparation method of described modified tourmaline comprises the following steps:
[0077] (1) Mix tourmaline and acid solution according to the solid-to-liquid ratio of 1g: 10mL, stir at 40°C at 200 rpm for 3 hours, perform suction filtration at a vacuum of 0.05MPa, and wash the obtained solid with deionized water until the eluate It is neutral, and then dried at 85°C for 8 hours to obtain acidified tourmaline;
[0078] (2) Mix acidified tourmaline and water according to the solid-to-liquid ratio of 1g: 10mL, stir at 94°C at 200 rpm for 15 minutes, add stannous chloride with a mass fraction of 1.5% of acidified tourmaline, and then add 30% tin Sulfuric acid aqueous solution, the solid-to-liquid ratio of acidified tourmaline and sulfuric acid aqueous solution is 1g: 0.2mL, continue to stir at 94 ℃ with 200 rpm for 45 minutes, add a mass fraction of 40% titanium tetrachloride aqueous solution, ...
