Embodiment 1
[0041] A high-toughness trash can, in terms of parts by mass, the formula of the plastic bucket includes: 50-60 parts of polypropylene, 15 parts of modified montmorillonite, 2 parts of ultraviolet absorber, 3 parts of filler, 1 part of lubricant and 0.5 part of flame retardant; the preparation method of the modified montmorillonite is: 1) adding cyanuric chloride to acetone, under ice-water bath conditions, stirring until cyanuric chloride is completely dissolved; 2) p-aminobenzene Sodium sulfonate is dissolved in deionized water to form a solution, and added dropwise to the solution of step 1), the pH of the solution is controlled at 5 during the dropwise addition, and after the dropwise addition, continue to stir for 2h; 3) raise the temperature of the system to Add tetramethylpiperidinamine to the above reaction system at 45°C, adjust the pH of the reaction system to 6.5, continue to stir for 5 hours, then cool to room temperature, centrifuge the obtained product and wash it...
Embodiment 2
[0056] A garbage can, in parts by mass, said plastic bucket formula comprising: 60 parts of polypropylene, 20 parts of modified montmorillonite, 5 parts of ultraviolet absorber, 5 parts of filler, 3 parts of lubricant and 3 parts of flame retardant Part; the preparation method of described modified montmorillonite is: 1) cyanuric chloride is joined in acetone, under the condition of ice-water bath, stir until cyanuric chloride dissolves completely; 2) sodium p-aminobenzenesulfonate is dissolved Make a solution in deionized water, and add it dropwise to the solution in step 1), and control the pH of the solution at 6 during the dropping process, and continue stirring for 2 to 4 hours after the dropping; 3) Raise the temperature of the system to 60°C , then add tetramethylpiperidinamine into the above reaction system, adjust the pH of the reaction system at 67.5, continue to stir for 5-6 hours, then cool to room temperature, centrifuge the obtained product and wash it with ethano...
Embodiment 3
[0058]A trash can, in parts by mass, the formula of the plastic bucket includes: 55 parts of polypropylene, 18 parts of modified montmorillonite, 4 parts of ultraviolet absorber, 4 parts of filler, 2 parts of lubricant and flame retardant 02 Part; the preparation method of described modified montmorillonite is: 1) cyanuric chloride is joined in acetone, under the condition of ice-water bath, stir until cyanuric chloride dissolves completely; 2) sodium p-aminobenzenesulfonate is dissolved Make a solution in deionized water, and add dropwise to the solution in step 1), the pH of the solution is controlled at 5 during the dropwise addition, and after the dropwise addition, continue to stir for 3 hours; 3) Raise the temperature of the system to 50°C, and then Add tetramethylpiperidinamine to the above reaction system, adjust the pH of the reaction system at 7, continue to stir for 5.5 h, then cool to room temperature, centrifuge the obtained product and wash it with ethanol, and dr...
