Embodiment Construction
[0009] Airless spray the first layer of solvent-free polyether polyurethane elastomer liquid 2 on the engraved silicone tape 1, enter the first drying tunnel 4 to heat and cure, the heating temperature is 90-120°C, and the heating time is 20-40 minutes. A layer of solvent-free polyether polyurethane elastomer liquid 2 is cured into a film with a thickness of 100 microns to 150 microns; after the film is conveyed out of the first drying tunnel 4 by the silicone belt 1, it is placed longitudinally on the cured film Put several polyester filaments or nylon filaments 6, the diameter of the polyester filaments or nylon filaments 6 is 30 microns to 50 microns, and the filaments play the role of strengthening the longitudinal tensile strength of the artificial turf; The second layer of solvent-free polyether polyurethane elastomer liquid 3 is airlessly sprayed on the silk 6, and the second layer of solvent-free polyether polyurethane elastomer liquid 3 is coated with polyester filamen...

Abstract
The invention discloses a manufacture method of artificial grass filaments with elastomers. The method comprises the following steps of: airlessly spraying a first layer of solvent-free polyether type polyurethane elastomer liquid on a silica gel belt with lines and entering a first drying path to heat and solidify into a film; longitudinally placing a plurality of polyester filaments or nylon yarns on the film and then airlessly spraying a second layer of solvent-free polyether type polyurethane elastomer liquid; sending into a second drying path to heat and solidify into an all-in-one film;embossing through roller press and then cutting into an infinitely long flat belt through a cutting device; and finally continuously rolling through a rolling device to manufacture the artificial grass filaments. The artificial grass filaments have permanent elasticity, simple and convenient mounting and longer service life, is softer than PE (polyethylene) or PP (polypropylene) artificial grass filaments and approach natural grass, thus the artificial grass filaments are more environmentally friendly.
Description
technical field [0001] The invention belongs to a method for manufacturing artificial turf silk for artificial turf, in particular to a method for manufacturing artificial turf silk with elasticity. Background technique [0002] The existing PE or PP artificial turf has poor elasticity, artificial turf is poured with fillers such as sand and rubber particles to increase the resilience, but long-term trampling makes the filler dense, the resilience decreases, and the filler is not environmentally friendly. Contents of the invention [0003] Aiming at the above-mentioned problems of the existing artificial turf, the present invention provides a new method for making artificial turf, and the artificial turf produced by this method overcomes the defect of poor elasticity of the existing artificial turf. [0004] The preparation method of artificial turf silk of the present invention is: [0005] Airless spray the first layer of solvent-free polyether polyurethane elastomer li...
