Embodiment 1
[0014] The bentonite dry powder is formulated into a 50% aqueous solution, and placed at room temperature for 24 hours to allow it to fully absorb water to form a semi-solid homogeneous system. Take 50 grams of bentonite aqueous solution with a concentration of 50% and mix it with 50 grams of acrylamide with a concentration of 30%. At the same time, add 4 milliliters of 30% NaOH and 1 milliliter of N-N methylenebisacrylamide with a concentration of 1PPM, and stir fully to form a semi-solid homogeneous phase system, and then placed in constant temperature water at 40°C 60 Polymerization under CO-γ-ray irradiation. After polymerization, the offset plate was pulverized, dried in an oven at 120° C., and pulverized into particles.
Embodiment 2
[0016] The dry bentonite powder is formulated into a 30% aqueous solution, and left at room temperature for 20 hours to allow it to fully absorb water to form a semi-solid homogeneous system. Take 20 grams of bentonite aqueous solution with a concentration of 30% and mix it with 80 grams of acrylamide with a concentration of 30%. At the same time, add 10 milliliters of NaOH with a concentration of 0.5% and 0.5 milliliters of N-N methylene bisacrylamide with a concentration of 2PPM. Solid homogeneous system, then placed in 40 ℃ constant temperature water 60 Polymerization under CO-γ-ray irradiation. After polymerization, the offset plate was pulverized, dried in an oven at 120° C., and pulverized into particles.
Embodiment 3
[0018] The talc dry powder is formulated into a 30% aqueous solution, and left at room temperature for 20 hours to allow it to fully absorb water to form a semi-solid homogeneous system. Take 40 grams of 30% talcum powder aqueous solution and 60 grams of 30% acrylamide, and add 5 milliliters of 10 percent NaOH solution and 1 milliliter of N-N methylene bisacrylamide at 1PPM. Stir to form a semi-solid homogeneous system, and then place it in 40°C constant temperature water 60 Polymerization under CO-γ-ray irradiation. After polymerization, the offset plate was pulverized, dried in an oven at 120° C., and pulverized into particles.
