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
The invention belongs to the preparation method of a kind of preparation method of artificial grass filaments of chinampa, particularly a kind of elastic artificial grass filaments.
Background technology
Existing P E or PP artificial grass filaments elasticity are bad, and fillers such as chinampa perfusion sand and rubber grain increase resilience, impel filler closely knit but trample for a long time, and resilience reduces, also not environmental protection of filler.
Summary of the invention
At the problems referred to above of existing artificial grass filaments, the invention provides a kind of preparation method of new artificial grass filaments, the artificial grass filaments that utilizes this method to produce is changed existing artificial grass filaments elasticity defect of bad.
The preparation method of the artificial grass silk of the present invention is:
Being carved with airless spraying first floor solvent-free polyether type polyurethane elastomer liquid on the silicone band of lines, enter first drying tunnel and be heating and curing, first floor solvent-free polyether type polyurethane elastomer liquid is cured into film; After film is sent out from first drying tunnel by silicone band, on the film that has solidified, vertically put some polyester capillariess or nylon yarn, and then on polyester capillaries or nylon yarn airless spraying second layer solvent-free polyether type polyurethane elastomer liquid, the second layer solvent-free polyether type polyurethane elastomer liquid of spraying is coated on polyester capillaries or nylon yarn wherein, and is bonded on the film of first floor solvent-free polyether type polyurethane elastomer liquid formation.They are together sent into the heating of second drying tunnel, second layer solvent-free polyether type polyurethane elastomer liquid also is cured gradually again, and the film that forms with first floor solvent-free polyether type polyurethane elastomer liquid is combined into one, and is solidified into the integral type film.Then the integral type film is sent to silica gel roller roll-in embossing.At last, cut into 3 millimeters～5 mm wide endless bandlets through cutting device again.Through the successive rolling of wrap-up artificial grass filaments.
The artificial grass silk of the present invention has permanent elasticity, and chinampa does not need filler, and also elasticity is better, simple installation.Because of the polyurethane life-span longer than PE or PP plastics, it is longer application life that the old friend makes the lawn.Moistening, capable of releasing negative ion because of the suction of polyurethane elastomer micropore, the artificial grass filaments surface roll is pressed with the vein lines, than PE or PP artificial grass filaments softness, near natural grass, so more environmental protection.
Description of drawings
Fig. 1 is the process flow diagram that the present invention makes artificial grass filaments.
Among the figure: 1 silicone band, 2 first floor solvent-free polyether type polyurethane elastomer liquid, 3 second layer solvent-free polyether type polyurethane elastomer liquid, 4 first drying tunnels, 5 second drying tunnels, 6 polyester capillariess or nylon yarn, 7 silica gel rollers, 8 cutting devices, 9 wrap-ups.
The specific embodiment
Airless spraying first floor solvent-free polyether type polyurethane elastomer liquid 2 on the silicone band 1 that is carved with lines, entering first drying tunnel 4 is heating and curing, 90～120 ℃ of heating-up temperatures, 20～40 minutes heat time heating times, first floor solvent-free polyether type polyurethane elastomer liquid 2 is cured into film, and film thickness is 100 microns～150 microns; After film is sent out from first drying tunnel 4 by silicone band 1, on the film that has solidified, vertically put some polyester capillariess or nylon yarn 6, the diameter of polyester capillaries or nylon yarn 6 is 30 microns～50 microns, and this silk thread plays the effect of strengthening the artificial grass filaments longitudinal tensile strength; And then on polyester capillaries or nylon yarn 6 airless spraying second layer solvent-free polyether type polyurethane elastomer liquid 3, the second layer solvent-free polyether type polyurethane elastomer liquid 3 of spraying is coated on polyester capillaries or nylon yarn 6 wherein, and is bonded on the film of first floor solvent-free polyether type polyurethane elastomer liquid 2 formation.They are together sent into 5 heating of second drying tunnel, 90～120 ℃ of heating-up temperatures, 20～40 minutes heat time heating times, second layer solvent-free polyether type polyurethane elastomer liquid 3 also is cured gradually, the film that forms with first floor solvent-free polyether type polyurethane elastomer liquid 2 is combined into one, be solidified into the integral type film, the integral thickness of the integral type film that is cured is 200 microns～300 microns.Then the integral type film is sent to silica gel roller 7 roll-ins, because the temperature of film is at this moment also higher, the cured layer that is formed by second layer solvent-free polyether type polyurethane elastomer liquid 3 on integral type film top also solidifies fully, embossing in the above after being carved with 7 roll-ins of lines silica gel roller.At last, cut into 3 millimeters～5 mm wide endless bandlets through cutting device 8 again.Through wrap-up 9 successive rollings artificial grass filaments.
Further, but the negative ion powder of its weight 1～3% of admixture mixes in solvent-free polyether type polyurethane elastomer liquid 2,3, and negative ion powder can be a tourmaline powder, its role is to increase the elastic body micropore, make its suction moistening, and discharge anion lastingly, purify air.
