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

Embodiment 1

[0029] 100 parts of EVA (ethylene-vinyl acetate copolymer resin) (parts by weight, the same below), 30 parts of talcum powder, 10 parts of rosin, 10 parts of paraffin wax, 10 parts of epoxidized soybean oil, 10101 parts of antioxidant.

Embodiment 2

[0031] 100 parts of EVA (ethylene-vinyl acetate copolymer resin), 100 parts of heavy calcium carbonate, 50 parts of rosin, 50 parts of paraffin, 20 parts of epoxy soybean oil, and 10102 parts of antioxidant.

[0032] Before the back glue is used, the components of the back glue formula other than EVA are firstly stirred in a container (such as a high mixer) and granulated, and then set aside.

[0033] The manufacturing process of the artificial turf of the present invention includes preparing the above-mentioned back adhesive formula components into a film and bonding it to the assembled grass fiber and grass bottom (hereinafter referred to as "turf"). The embodiment of the specific manufacturing process is described as follows.

[0034] Manufacturing process implementation plan one

Embodiment approach 2

[0036]The components of the pretreated back adhesive formula except EVA are uniformly mixed with EVA to prepare a hot-melt film. The prepared hot-melt film is transported by the conveying roller and tightly attached to the back of the turf through the pressing shaft. Move the hot-melt film and turf towards the hot air box at the same speed, and at the same time, provide a suction box under the turf to suck air downward, and when the hot-melt film and turf pass through the hot air box, there is hot air in the hot air box (110 ℃~150℃) from top to bottom to blow the hot-melt film, so that the hot-melt film and the turf are bonded together.

[0037] Manufacturing process implementation plan three

[0038] Mix the components of the pretreated adhesive formula except EVA with EVA, and cast a hot melt film through an extruder and a casting die. The hot-melt film is directly attached to the back of the turf, and the two pass through the hot air box together. In the hot-air box, hot ...

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 rubberinto 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] Fig. 1 shows the structure of existing artificial turf, 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 polymer m...
