Embodiment 1
[0026] Weigh 100g of acrylic acid monomer and 2g of AIBN into a 250mL ground-mouth Erlenmeyer flask, plug the bottle with a vacuum glass stopper, place the Erlenmeyer flask in a water bath at about 20°C with constant magnetic stirring, and wait until the AIBN is completely dissolved. Weigh 60g of sodium-based montmorillonite into the conical flask, stir at constant temperature and speed for about 2 hours, then pour the mixture in the conical flask into a petri dish and put the petri dish into an oven at 100°C. Initiation temperature of substance implosion, implosion reaction (a large amount of white smoke is produced, the muddy mixture in the petri dish boils and splashes, and dries quickly in an instant), and then the sediment in the petri dish is taken out after being thoroughly dried, ground and passed 300 mesh sieve to obtain the target product.
Embodiment 2
[0028]Weigh 10g of acrylic acid, 10g of methyl acrylate, 20g of ethyl acrylate, 20g of butyl acrylate, 20g of isooctyl acrylate, 20g of hydroxyethyl acrylate monomer and 0.1g of AIBN in a 250mL ground-mouth Erlenmeyer flask, and stopper with a vacuum glass stopper Bottle mouth, place the Erlenmeyer flask in a water bath at about 20°C with constant speed magnetic stirring. After the AIBN is completely dissolved, weigh 40g of Na-based montmorillonite into the Erlenmeyer flask, stir at constant temperature and speed for about 3 hours, and then put the conical Pour the mixture in the bottle into a petri dish and spread it out, put the petri dish into an oven at 100°C, when the temperature rises to the temperature at which the polymer implosion is initiated, the implosion reaction occurs, and then the sediment in the petri dish is completely dried, then taken out and ground And pass through a 500-mesh sieve to obtain the target product.
Embodiment 3
[0030] Weigh 10g hydroxypropyl acrylate, 10g hydroxybutyl acrylate, 10g methacrylic acid, 20g methyl methacrylate, 20g ethyl methacrylate, 20g butyl methacrylate, 10g hydroxyethyl methacrylate monomer and Put 5g of azobisisoheptanonitrile (ABVN) in a 250mL ground-mouth Erlenmeyer flask, plug the bottle mouth tightly with a vacuum glass stopper, place the Erlenmeyer flask in a water bath at about 20°C with constant magnetic stirring, and wait until the ABVN is completely dissolved. Weigh 100g of sodium-based montmorillonite into the conical flask, stir at constant temperature and speed for about 1 hour, then pour the mixture in the conical flask into a petri dish and put the petri dish into a 90°C oven. The precipitate in the petri dish was thoroughly dried and taken out, ground and passed through a 1000-mesh sieve to obtain the target product.
