Example Embodiment
[0024] Example 1
[0025] Place the paraffin wax in a crucible and heat it to melt completely at a temperature of 60°C to obtain molten paraffin. Put sodium peroxide and molten paraffin in a No. 1 beaker at a mass ratio of 1:10, and stir and mix with a glass rod for 20 minutes , Get the mixed slurry, and then put the mixed slurry in a freezer pulverizer to freeze and smash to obtain the coated sodium peroxide; add the gelatin powder and water according to the mass ratio of 1:100 into the No. 2 beaker, stir and mix with a glass rod for 30 minutes After that, let it stand and swell for 4 hours, and then move the No. 2 beaker into a digital speed-measuring constant-temperature magnetic stirrer. Under the conditions of a temperature of 65°C and a speed of 500r / min, heat and stir to dissolve for 50 minutes to obtain a gelatin liquid; The liquid was placed in a three-necked flask at a volume ratio of 1:30, stirred and mixed for 30 minutes at a speed of 500r / min, and then added 8 times ...

[0026] Example 2
[0027] Add the gelatin powder and water to the No. 2 beaker at a mass ratio of 1:100, stir and mix with a glass rod for 30 minutes, and then let it stand for 4 hours to swell, and then move the No. 2 beaker into the digital display speed constant temperature magnetic stirrer at 65℃ , At a speed of 500r / min, heat and stir to dissolve for 50min to obtain a gelatin liquid; put the linseed oil and the gelatin liquid in a three-necked flask at a volume ratio of 1:30, and stir and mix for 30min at a speed of 500r / min. Then add 8 times the volume of the gelatin solution to the sodium sulfate solution in the three-necked flask, stir and mix for 30 minutes at a speed of 300r / min, then place the three-necked flask in an ice-water bath, and reduce the temperature in the three-necked flask to 15℃ , Then add formaldehyde solution of 2 times the volume of linseed oil to the three-necked flask, and then add 30% ammonia water to adjust the pH to 9.5 in the three-necked flask, ...
