Abstract

The invention relates to a piece of PET anti-grass cloth. The PET anti-grass cloth comprises a PET raw material, auxiliary agents and nano-silver. The auxiliary agents include an anti-oxidant, a filler, an adhesion agent, a flexibilizer and a color masterbatch or include an anti-oxidant, a filler, a flexibilizer and a color masterbatch, wherein the weight ratio of PET raw material to anti-oxidant to filler to adhesion agent to flexibilizer to color masterbatch to nano-ilver is 88-89: 2: 3: 1: 3: 3: 0.1. The tensile strength of the PET anti-grass cloth is improved by 30 to 50%; the PET anti-grass cloth is free of damage after outdoor usage for 2 to 3 years; the PET anti-grass cloth is capable of increasing earth temperature by 1 to 3 DEG C and increasing output by 20 to 40%; and the PET anti-grass cloth has an oxygen index of more than 26 and glossiness of no less than 110%.

Description

technical field [0001] The invention relates to a PET weed-proof cloth and a production method thereof, in particular to a method for producing a weed-proof cloth by using waste PET plastic bottle flakes or PET slices, and belongs to the technical field of horticultural applications. Background technique [0002] Grass-proof cloth is a kind of film-like ground covering material that is resistant to friction and aging and is made of high-density woven polyethylene and polypropylene flat wires that are resistant to ultraviolet rays. It is mainly used for ground weed control, drainage, and keeping the ground clean. ground marking and guidance purposes. At present, weed-proof cloth covering measures have been applied to grapes, pears, citrus and other fruit trees. Covering can inhibit the growth of weeds in orchards, maintain soil moisture, and reduce management labor costs. [0003] During the use of polyethylene and polypropylene grass-proof cloth, it was found that it had th...
