Pigment Requirements For Artificial Turf

Pigment green 36 manufacturer said, artificial turf compared to natural grass has a lot of incomparable advantages, it is not only good weather resistance, no matter what kind of season can be used, and good durability, the use of a long time and the late management and maintenance costs are low, and its surface layer can also be recycled and reused, environmental performance, in line with the city’s environmental requirements.

At the same time the shock absorbing performance of artificial turf is also very good, many international top competitions and domestic competitions are carried out in the artificial turf, in the sports field, athletes if the fall damage occurs, artificial turf is safer than the natural lawn, it has a certain cushioning effect of the impact, which is also the artificial lawn is superior to the role of the natural lawn of one of the aspects of the artificial lawn, therefore, in recent years, artificial lawn market is developing rapidly.

Artificial sports lawn is made of plastic as the main raw material, cast into film, cut into monofilaments, and then woven into the lawn with professional equipment. While the plastic polymers are PP, PE, PA, PP grass filament material hardness, these polymers can provide the flexibility and elasticity of the lawn filament. So what are the requirements for the pigments used in the manufacture of artificial turf?

Weather Resistance
Since artificial turf is used outdoors, it should be able to withstand cold winter and hot summer, and can be used normally in rain and snow, and artificial turf is often used in school soccer stadiums or all kinds of training grounds, so the selected pigment should have very excellent weather resistance.

Heat Resistance
Artificial sports turf silk using melt spinning molding process, so the heat resistance of the pigment to withstand the high temperature of about 250 ℃, and at the same time require the use of the pigment must have good migration resistance, to prevent the use of artificial turf in the process of fading phenomenon.

Dispersion
Due to the artificial sports turf silk using melt spinning molding process, and there are a lot of shaped silk, so the pigment used should have good dispersion, otherwise it will cause hair, broken silk, but also affect the normal weaving production.

Aging Resistance
Artificial sports lawn is polymer, to maintain the weather resistance of polymer, it is necessary to control the free metal ions in the pigment to delay the aging of polymer. In the role of heat, light and other polymers will occur under the chain breakage, resulting in performance degradation, so the need to add anti-aging agents such as hindered phenolic antioxidants, to inhibit or reduce the thermal oxidation reaction of the plastic, to extend the service life of plastic products.

Polymer aging stabilization system should also add benzophenone class ultraviolet absorber to improve the weathering resistance of artificial turf. At the same time in the artificial turf plastic system to join the flame retardant system to ensure the safety of use, because of the addition of halogen flame retardant system is acidic, so avoid the use of light stabilizers with strong alkaline functional groups hindered amine class together.
