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...

Abstract

The invention discloses a high-toughness garbage can. According to the high-toughness garbage can, the plastic can formula comprises the following components of, in parts by mass, 50-60 parts of polypropylene, 15-20 parts of modified montmorillonite, 2-5 parts of an ultraviolet light absorber, 3-5 parts of filler, 1-3 parts of a lubricating agent and 0.5-3 parts of a flame retardant. When the garbage can is used outdoors, the ultraviolet light absorber can absorb ultraviolet light in sunlight and does not change, and irradiation of the ultraviolet light to polypropylene is reduced, so that ageing of the garbage can is slowed down, and the service life of the garbage can is prolonged; the filler is added into raw materials of the garbage can, the physical and mechanical properties of the garbage can are enhanced, and the production cost of the garbage can is reduced; and through adding the lubricant, the friction force between the raw materials and between the raw materials and processing equipment can be reduced, so that the flow resistance of the melt is reduced, the viscosity of the melt is reduced, the flowability of the melt is improved, the adhesion between the melt and the equipment is avoided, the surface smoothness of a product is improved, and the quality of the garbage can is improved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a high-toughness trash can and a preparation method thereof. Background technique [0002] In all public places in the city, such as shopping malls, hotels, restaurants, office buildings, and offices, trash cans will be placed to facilitate people to discard rubbish such as paper scraps. However, with the development of the economy and the improvement of life, people's requirements for trash cans are getting higher and higher, so there are many kinds of trash cans on the market, each of which has different design concepts, and strives to meet the requirements of different users. . [0003] When the trash can is used outdoors for a long time, because polypropylene is very sensitive to ultraviolet rays, it is easily affected by light, heat and oxygen outdoors, causing aging degradation of polypropylene materials and deterioration of mechanical properties, whic...
