Embodiment 1

[0012] Example 1: First use knitting to tuft the artificial turf on the base fabric; select a thermoplastic resin that has an excellent bonding effect with the artificial turf but has a poor bonding effect with the base fabric or the two cannot be bonded, and heat it to melt State, make it evenly distributed on the back of the base cloth through the heat sealing process, and form a back adhesive layer after cooling and curing; separate the base cloth from the back adhesive layer, and the artificial grass silk is bonded and fixed on the back adhesive layer, that is, a kind of Artificial turf that can be recycled as a whole.

Embodiment 2

[0013] Embodiment 2: first use knitting to tuft the artificial turf on the base cloth; select an adhesive material that has an excellent bonding effect with the artificial turf but a poor bonding effect with the base cloth or the two cannot be bonded, and heat it to In the molten state, it is evenly distributed on the back of the base cloth through the coating process, and the adhesive layer is formed after cooling and solidification; the base cloth is separated from the adhesive layer, and the artificial grass silk is bonded and fixed on the adhesive layer, which is formed An artificial lawn that can be recycled as a whole.

Abstract

The invention discloses a process for manufacturing artificial turf. The method comprises the steps that firstly, artificial turf fibers are arranged on a base fabric in a knitting and tufting mode; then, a thermoplastic material is heated to be of a molten state, is uniformly distributed on the back surface of the base fabric through the coating process or the heat sealing process, and forms a back adhesive layer after being cooled and solidified; the base fabric is separated from the back adhesive layer, the artificial turf fibers are fixed to the back adhesive layer in a bonding mode, and then the artificial turf capable of being wholly recycled is formed. The effect of bonding between the thermoplastic material serving as the back adhesive layer and the artificial turf fibers is excellent, but the effect of bonding between the thermoplastic material and the base fabric is poor or can not be achieved at all. The thermoplastic material serves as the back adhesive layer of the artificial turf, a base fabric structure of the finished product is omitted, the turf fibers and the back adhesive layer meet the requirement for wholly recycling the materials, and therefore the sustainable development of environment is maintained. The artificial turf is simple in structure, easy to manufacture and suitable for industrialization, saves the raw materials, lowers the cost and enables the resources to be recyclable.

Description

technical field [0001] The invention relates to a novel artificial turf manufacturing process, in particular to an artificial turf manufacturing process capable of realizing overall recovery and recycling. Background technique [0002] Existing artificial turf consists of three components: grass silk, base cloth and back glue. Wherein, the grass silk is made of thermoplastic material polyethylene, polypropylene and / or polyamide material, the base cloth is made of polypropylene material, and the back glue is made of thermosetting material carboxylated styrene-butadiene rubber or polyurethane. Thermoplastic materials can be recycled, while thermosetting materials cannot be recycled and can only be decomposed by incineration. Therefore, the existing artificial turf is limited by the production materials, and cannot be recycled as a whole, resulting in a certain waste of materials, and at the same time, its treatment method also causes certain pollution to the environment.
