[0017] First, weigh 30g of methyl methacrylate, 25g of hydroxyethyl acrylate, 20g of butyl acrylate, 25g of acrylic acid and 3g of dibenzoyl peroxide, stir and mix evenly to obtain a mixed solution, add 150mL of n-butyl methacrylate to a 500mL three-necked flask Alcohol, put it into an oil bath and heat up to 115°C, slowly drop the mixed solution into the three-necked flask at this temperature, control the dripping in 40 minutes, keep stirring and react for 3 hours after the dripping, cool down to 60°C after the reaction, and reduce the temperature. Distill under pressure for 1 h, mix the distilled liquid with deionized water at a volume ratio of 1:4, adjust the pH to 10.5 with 20% sodium hydroxide by mass fraction, and stir for 10 min after adjustment to obtain a viscous liquid, which is set aside; 5g of nano-montmorillonite, 1g of glass, 3g of alumina, 1g of asbestos fiber, stirred and mixed, put into the jet mill, and crushed into a mixed powder with a particle size of 10μm;...

[0020]First, weigh 40g of methyl methacrylate, 30g of hydroxyethyl acrylate, 25g of butyl acrylate, 28g of acrylic acid and 4g of dibenzoyl peroxide, stir and mix evenly to obtain a mixed solution, and add 175mL of n-butyl to a 500mL three-necked flask Alcohol, put it into an oil bath and heat up to 118°C, slowly drop the mixed solution into the three-necked flask at this temperature, control the dripping in 50 minutes, keep stirring and react for 3 hours after the dripping, and cool down to 63°C after the reaction. Distill under pressure for 1 hour, mix the distilled liquid with deionized water at a volume ratio of 1:4, and adjust the pH to 10.8 with 20% sodium hydroxide by mass fraction, and stir for 13 minutes after adjustment to obtain a viscous liquid for subsequent use; 8g of nano-montmorillonite, 1g of glass, 4g of alumina, 2g of asbestos fiber, stirred and mixed, put into the jet mill, and crushed into a mixed powder with a particle size of 13μm; then weighed 150g of de...
