Embodiment 1
[0052] 1. Select natural rubber, put it into liquid nitrogen and keep it for 10 minutes, then take it out, and use a pulverizer to prepare nanoparticles with an average particle size of 400nm as the core component X of component C for later use;
[0053] 2. Select gum arabic as the coating agent Z1 of the inner core X, and prepare an aqueous solution with a mass fraction of 10% for later use;
[0054] 3. Based on 100 parts by weight of the core X content, take 100 parts of the core component X particles and 10 parts of the solution of the coating agent Z1, mix and coat evenly at a speed of 4000r / min by a high-speed mixer, and place it in a vacuum drying oven , drying at 50°C for 2 hours to obtain component C with a core-shell structure;
