Problems solved by technology

However, the surface hardness of polypropylene and polyethylene is low, the bearing capacity is poor, it is easy to wear, and it is not resistant to aging; while the artificial turf is frequently used and wears heavily, which makes the artificial turf prone to split ends after long-term frequent use. Hair loss, and breakage phenomenon

Embodiment 1

[0025] A preparation method for recycling PET bottle flakes to produce wear-resistant regenerated artificial turf, the method comprises the following steps:

[0026] (1) Crushing and cleaning: Cut and crush waste polyester bottles into flakes with a diameter of 8-20mm, and then hot wash and dehydrate with clean water at a temperature of 60-80°C;

[0027] (2) Weighing raw materials: including the following components in parts by weight: 117 parts of recycled PET, 2 parts of masterbatch, 2 parts of flame retardant, 1.5 parts of heat stabilizer, 1 part of toughening agent, terpene 8 parts of resin, 1.5 parts of PEG, 2 parts of SEBS-g-MAH, 2 parts of antioxidant, 21 parts of filler;

[0028] (3) Rapid drying: the raw materials are fed into the vacuum drum dryer through the feeder and continuously rolled and stirred, heated by the heating mantle to 140°C~180°C for crystallization for 1 hour, and then dried at this temperature for 4~6 Hours, during which the vacuum pump is used to ...

Abstract

The invention discloses a preparation method for producing a wear-resistant generated artificial straw filament from recycled PET bottle flakes. The method comprises the following steps: drying amorphous polyester bottle flakes in a low-temperature drying way; and re-proportioning the dried bottle flakes, uniformly mixing the dried bottle flakes, then, pouring the mixture into a spinning storage bin, then, feeding into a screw extruder for extrusion melting to obtain a melt, and carrying out metering, spinning, cooling and oiling, traction feeding, rolling and low-temperature stretching. The generated artificial straw filament prepared by using the preparation method disclosed by the invention has the characteristics of high strength, long service time and good wear resistance and toughness; and the preparation method is simple and easy to operate, low in cost, high in performance cost ratio, environment-friendly, energy-saving and capable of producing the wear-resistant generated artificial straw filament from the recycled PET bottle flakes and further widening the recycle space of waste PET.

Description

technical field [0001] The invention belongs to the technical field of recycling waste PET bottle flakes, and in particular relates to a preparation method of recycling PET bottle flakes to produce wear-resistant regenerated artificial turf. Background technique [0002] Polyethylene terephthalate (PET) is widely used in various fields because of its good physical and chemical properties, mainly used to make fibers, films and beverage bottles. With the rapid increase in the production and sales of PET polyester, a large amount of waste polyester is discharged into nature. Due to its large size, it is difficult to degrade under natural conditions, which has brought heavy pressure to the natural environment. Therefore, waste polyester is often recycled and used many times to turn waste into treasure. At present, artificial turf has been widely used in various sports venues and leisure venues. [0003] Artificial turf fiber is the core material of artificial sports turf, and ...
