Novel synthetic turf and method for producing the same

Abstract

The invention provides a novel artificial turf, a method for manufacturing the same and a recycled material prepared from the artificial turf through recycling. The artificial turf comprises grass fiber, grass bottom part and back rubber, wherein the grass fiber and the grass bottom part are mainly made from polyethylene and polypropylene respectively; and the back rubber is made from ethylene vinyl acetate copolymer resin (EVA) as a main material together with a filler, tackifying resin, a conditioning agent, a plasticizer, an antioxidant and the like which are added into the main material. The artificial turf is made by adhering the back rubber to the grass bottom part provided with the grass fiber; and the adhesion can be achieved in two modes: the first mode is to make the back rubber into a thin film firstly and then adhere the back rubber to the grass bottom provided with the grass fiber; and the second mode is to make the back rubber into a thin film through casting and adhere the thin film to the grass bottom provided with the grass fiber simultaneously. The artificial turf can be recycled integrally to obtain a useful recycled composite material, so as to eliminate environmental pollution and reduce the recycling cost.

Description

technical field [0001] The present invention relates to a novel artificial turf and its manufacturing method, and more particularly to an ethylene-vinyl acetate copolymer (EVA)-containing artificial turf and its manufacturing method. Background technique [0002] Because artificial turf has the advantages of anti-aging, sun protection, waterproof, non-slip, wear-resistant, comfortable feet, bright color, long service life, low maintenance costs, and all-weather use, it has recently been used in stadiums, schools, hotels and buildings. It has been widely used in many occasions such as roofs. [0003] figure 1 The structure of the existing artificial turf is shown, which is mainly composed of grass fiber, grass bottom and back glue. Usually, grass fibers and grass bottoms are made of thermoplastic polymer materials, such as grass fibers are mainly made of polyethylene, grass bottoms are mainly made of polypropylene, and back glue is usually made of thermosetting cross-linked...

AI Technical Summary

Problems solved by technology

[0006] The present invention aims at the problems that existing artificial turf materials are incompatible with each other and cannot be uniformly recycled, and proposes a new type of artificial turf, in which hot-melt ethylene-vinyl acetate copolymer (EVA) resin is used as the main adhesive Material

Therefore, the artificial turf manufactured according to the present invention solves the problem that the existing artificial turf cannot be uniformly recycled
