Problems solved by technology

The physical recycling method is mainly to physically reprocess waste plastics to put them back into use. However, recycled plastics have many impurities, poor performance, and the number of repeated recycling is limited. Therefore, chemical recycling of PET recycling by chemical methods is currently the main recycling method. method

Embodiment Construction

[0015] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0016] First weigh 0.3g zinc nitrate (Zn(NO 3 ) 2 ·6H 2 O) Add it to 64 milliliters of N-methylpyrrolidone (NMP) solvent, stir well at room temperature to make it dissolve completely, then transfer the solution to a polytetrafluoroethylene liner with a volume of 100 mL for subsequent use. Take a discarded plastic bottle, cut it into pieces, weigh 0.3g and add it to the polytetrafluoroethylene liner, then pack the polytetrafluoroethylene liner tightly in the hydrothermal reaction kettle, and put the packaged hydrothermal reaction kettle Heat at 150°C for 24 hours in a blast drying oven. After the reaction is completed, the reactor is cooled to room temperature, centrifuged and washed three times with NMP and methanol to remove excess reactants, and finally the obtained sampl...

Abstract

The invention provides a method for preparing a metal organic framework material from PET (polyethylene terephthalate) waste materials. Along with the fast development of human society, the resource lack and environment problems cause more and more attention of people, wherein the high efficiency resource recovery and utilization is a bridge for simultaneously solving the resource lack and environment problems. Plastic bottles are common waste materials in the life, and have the main ingredients of polyethylene terephthalate which has the chemical formula of COC6H4COOCH2CH2O, the English nameof polyethylene terephthalate and the abbreviation of PET. Experiments prove that the PET can be used for synthesizing metal-organic framework materials MOF-5; the metal-organic framework material canbe used in various fields. The method provides a method for realizing the high-efficiency PET recovery.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a metal-organic framework material MOF-5, which is synthesized from waste plastic bottles PET. Background technique [0002] At present, many plastic bottles are made of PET. However, PET materials are chemically inert and difficult to be degraded naturally. When they are discarded, the chemicals they contain remain intact in the soil, occupying a lot of space, causing white Pollution has brought enormous pressure to environmental protection work. [0003] Plastic bottles are a common waste in life, and its main component is polyethylene terephthalate, whose chemical formula is COC 6 h 4 COOCH 2 CH 2 O, the English name Polyethylene terephthalate, referred to as PET. At present, physical recycling and chemical recycling are mainly used to process PET. The physical recycling method is mainly to physically reprocess waste plastics to put them back into use. However, recyc...
