preparation example Construction
[0044] The present invention also provides a preparation method of the carbon microspheres, which includes the following steps:
[0045] Step 1: Wash and dry the waste plastic;
[0046] Step 2: Heat and mix the waste plastic obtained in Step 1, absolute ethanol and an activator, and then add a catalyst for reaction;
[0047] Step 3: Add degradation agent to the system obtained in step 2 to continue the reaction, and then leave it to cool;
[0048] Step 4: Dry the product obtained in Step 3 and continue calcining to obtain the carbon microspheres.
[0049] Preferably, in the step 1, the waste plastics are cleaned by ultrasonic waves, and then the water is filtered by a mesh screen; preferably, the above-mentioned process is repeated three times.
[0050]The present invention also provides the carbon microspheres prepared by the above method.
[0051] The present invention also provides the application of the carbon microspheres in conductive inks, adsorption materials, catal...
Embodiment 1
[0067] 1. Cut 50g of recycled waste plastic into flakes, place them in a beaker, pour 50g of deionized water into the beaker and stir with a glass rod, put the beaker into an ultrasonic cleaner for cleaning for 1 hour, and then discard the waste in the beaker Pour out the plastic and filter through a 120-mesh sieve to remove water. Repeat the above process 3 times, and finally put the discarded plastic pieces in a 120-mesh sieve to dry, and after 24 hours of natural air-drying in the air, put them in a vacuum drying oven with a vacuum degree of 0.05MPa and a temperature of 50°C Dry for 8 hours;
[0068] 2. Put the measured waste plastic pieces and 10g of absolute ethanol into a three-necked flask connected with a stirring device, place it in an oil bath heating device, add 20g of simethicone to the three-necked flask, and raise the temperature to 180 ℃-200℃, stir and mix, after 90 minutes, drop 1g of n-butyl titanate into the mixed system, and react the system for 2 hours und...
Embodiment 2
[0072] 1. Cut 70g of recycled waste plastic into flakes, place them in a beaker, pour 70g of deionized water into the beaker and stir with a glass rod, put the beaker into an ultrasonic cleaner for 1 hour, and then discard the waste in the beaker Pour out the plastic and filter through a 120-mesh sieve to remove water. Repeat the above process 3 times, and finally put the discarded plastic pieces in a 120-mesh sieve to dry, and after 24 hours of natural air-drying in the air, put them in a vacuum drying oven with a vacuum degree of 0.05MPa and a temperature of 50°C Dry for 8 hours;
[0073] 2. Put the measured waste plastic pieces and 15g of absolute ethanol into a three-necked flask connected with a stirring device, place it in an oil bath heating device, add 40g of simethicone to the three-necked flask, and raise the temperature to 180 ℃-200℃, stirring and mixing, after 90 minutes, drop 4g of n-butyl titanate into the mixed system, and the system reacted for 2 hours under s...
