Embodiment 1

[0033] An anti-aging trash can specifically includes the following components: 50kg of polypropylene, 20kg of modified montmorillonite, 5kg of ultraviolet absorber, 3kg of filler, 1kg of lubricant and 3kg of flame retardant, wherein the preparation method of modified montmorillonite As follows: 1) Add cyanuric chloride to acetone, under ice-water bath conditions, stir until cyanuric chloride is completely dissolved; 2) Dissolve sodium p-aminobenzenesulfonate in deionized water to make a solution, and drop by drop Add it to the solution in step 1), and control the pH of the solution to 5 during the dropwise addition. After the dropwise addition, continue to stir for 2 hours, and the molar ratio of sodium p-aminobenzenesulfonate to cyanuric chloride is 1:1; When the temperature reaches 45°C, add tetramethylpiperidinamine to the above reaction system, the molar ratio of tetramethylpiperidinamine to cyanuric chloride is 1:1, adjust the pH of the reaction system to 6.5, and continue...

Embodiment 2

[0040] An anti-aging trash can specifically includes the following components: 55kg of polypropylene, 15kg of modified montmorillonite, 2kg of ultraviolet absorber, 4kg of filler, 2kg of lubricant and 0.5kg of flame retardant, wherein the preparation of modified montmorillonite The method is as follows: 1) Add cyanuric chloride to acetone, under the condition of ice-water bath, stir until the cyanuric chloride is completely dissolved; 2) Dissolve sodium p-aminobenzenesulfonate in deionized water to make a solution, and dropwise Add dropwise to the solution in step 1), the dropwise addition process controls the pH of the solution to be 6, after the dropwise addition, continue to stir for 4h, the molar ratio of sodium p-aminobenzenesulfonate to cyanuric chloride is 1:1; 3) rise When the temperature of the system reaches 60°C, add tetramethylpiperidinamine to the above reaction system, the molar ratio of tetramethylpiperidinamine to cyanuric chloride is 1:1, adjust the pH of the r...

Embodiment 3

[0047] An anti-aging trash can specifically includes the following components: 60kg of polypropylene, 18kg of modified montmorillonite, 5kg of ultraviolet absorber, 4kg of filler, 3kg of lubricant and 2kg of flame retardant, wherein the preparation method of modified montmorillonite As follows: 1) Add cyanuric chloride to acetone, under ice-water bath conditions, stir until cyanuric chloride is completely dissolved; 2) Dissolve sodium p-aminobenzenesulfonate in deionized water to make a solution, and drop by drop Add it to the solution in step 1), and control the pH of the solution to 5.5 during the dropwise addition. After the dropwise addition, continue to stir for 3 hours, and the molar ratio of sodium p-aminobenzenesulfonate to cyanuric chloride is 1:1; When the temperature reaches 55°C, add tetramethylpiperidinamine to the above reaction system, the molar ratio of tetramethylpiperidinamine to cyanuric chloride is 1:1, adjust the pH of the reaction system to 7, and continue...

Abstract

Relating to the technical field of garbage cans, the invention relates to an anti-aging garbage can and a preparation process thereof. The anti-aging garbage can comprises the following components bymass: 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 lubricant and 0.5-3 parts of a flame retardant. According to the invention, cyanuric chloride, sodium sulfanilate and tetramethylpiperidine amine are employed to synthesize a hindered amine light stabilizer, and through ion exchange, the hindered amine light stabilizer is intercalated to the interlayer of montmorillonite, the prepared modified montmorillonite has anti-aging effect, and the modified montmorillonite is uniformly dispersed inpolypropylene, thus guaranteeing a consistent anti-aging effects at all parts. The anti-aging garbage prepared according to the invention has the effects of excellent anti-aging performance and prolonged service life.

Description

technical field [0001] The invention relates to the technical field of trash cans, in particular to an anti-aging trash can and a preparation process thereof. Background technique [0002] Garbage disposer, has another name called litter box or dustbin, is a container specially for holding rubbish, waste. Trash cans are rich in materials, mainly including plastic, ceramics, stainless steel, wood, cement, pulp, metal, glass steel, steel and wood, etc. Plastic trash cans have the advantages of simple processing, easy cleaning, wide application range, and low price. be more and more widely used. At present, plastic trash cans on the market are mainly made of high-density polyethylene or polypropylene. Polypropylene is more widely used because of its excellent physical and chemical properties. Polypropylene is a non-toxic, odorless, highly crystalline polymer that is extremely stable to water. In terms of thermal stability, polypropylene will not degrade at 100°C and has good ...
