[0020] like figure 1 As shown, the preparation method of the curable stripped high-viscosity radioactive aerosol press preparation of the embodiment of the present invention comprises the following steps:
[0021] S101: Preparation of matrix polyvinyl alcohol, 2 to 9 parts of polyvinyl alcohol, dissolved in 40 to 50 parts of deionized water, heated and stirred until dissolved, uniform and transparent without particles, kept at 90°C, and set aside;
[0022] S102: Preparation of monomer initiator mixed solution, monomer acrylamide (AM) 1-5 parts, initiator ammonium persulfate (APS) 0.01-0.05 parts, wherein the amount of initiator ammonium persulfate (APS) is the monomer 1 to 1.5 wt% (mass fraction) of the amount of acrylamide (AM), dissolved in 30 to 40 parts of solvent deionized water to obtain a monomer initiator mixed solution, stirred until fully dissolved, placed in a cool and dry place, and used;
[0023] S103: Synthesis of polymer polymerization solution, cool down the p...
Embodiment 1
[0029] 1. Preparation of Polymer Solution
[0030] Put 600g of polyvinyl alcohol (PVA1799) and 2000ml of deionized water in a reaction kettle, heat up to 90°C, stir for 90min until the polyvinyl alcohol is completely dissolved, cool down to 80°C, and keep warm for later use.
[0031] 60 g of acrylamide (AM) monomer and 0.6 g of ammonium persulfate (APS) initiator were dissolved in 1200 ml of deionized water to form a monomer initiator mixed solution, ready for use.
[0032] Add the monomer initiator mixed solution dropwise at a rate of 2 drops / second. After 80 minutes, the dropwise addition is completed. After the monomer initiator mixed solution has been dripped, keep it warm for 200 minutes, cool down and discharge to obtain a polymer polymerization solution.
[0033] 2. Preparation of radioactive aerosol compression preparation
[0034] Measure 1L of the polymer solution, heat to 40°C, add 10g of gelatin, stir for 30 minutes (rotating speed 250-400rpm), cool down to room t...
Embodiment 2
[0042] 1. Preparation of matrix polyvinyl alcohol
[0043] Dissolve 2-9 parts of polyvinyl alcohol (PVA1799) in 40-50 parts of deionized water, heat and stir until dissolved, and when it is uniform and transparent without particles, keep warm at 90°C and set aside.
[0044] 2. Preparation of monomer initiator mixed solution
[0045] 1-5 parts of monomer acrylamide (AM), 0.01-0.05 parts of initiator ammonium persulfate (APS), wherein the amount of initiator ammonium persulfate (APS) is 1-1.5wt of the amount of monomer acrylamide (AM) % (mass fraction), dissolved in 30 to 40 parts of solvent deionized water to obtain a monomer initiator mixed solution, stirred until fully dissolved, placed in a cool and dry place, and set aside.
[0046] 3. Synthesis of Polymer Solution
[0047] Cool down the polyvinyl alcohol solution prepared in step 1, the temperature range is 60-80°C, the stirring speed is 200-450rpm, and the monomer initiator mixed solution in step B is added dropwise wit...
