Problems solved by technology

[0003] At present, people's research on the wear resistance of grass silk is mainly focused on changing the shape of grass silk, such as patent 200920101996.X, but there are few studies on improving the wear resistance of grass silk by modifying grass silk raw materials. CN101476174A discloses a kind of enhanced artificial turf, by adding inorganic nanoparticles to improve the strength of artificial turf, if it is produced according to the production process announced by it, inorganic nanoparticles form a reinforced masterbatch through high mixing, then the agglomeration of inorganic nanoparticles is relatively Seriously, it leads to uneven dispersion of inorganic nanoparticles on the surface of artificial turf fibers, which increases the wear rate of artificial turf fibers and greatly reduces the function of inorganic nanomaterials to strengthen grass fibers, especially for improving the wear resistance of artificial turf fibers. Unsatisfactory effect

Abstract

The invention relates to a wear-resistant artificial turf fiber made of the following raw materials by weight: 60 to 95 parts of matrix resin, 1 to 10 parts of wear-resistant masterbatch, 1 to 10 parts of color masterbatch, and 2 to 5 parts of age resister; and the wear-resistant masterbatch contains silicone powder. The wear-resistant artificial turf fiber has a greatly improved wear resisting property, thereby being suitable for places such as schools and the like where the wear-resistant artificial turf fiber is required to be used frequently for a long time. The wear-resistant artificial turf fiber has the advantages that the preparation method is simple; and the cost is low.

Description

technical field [0001] The invention relates to an artificial turf fiber, in particular to an artificial turf fiber with good abrasion resistance. Background technique [0002] At present, artificial turf has been widely used in various sports venues and leisure venues. Artificial turf fiber is the core material of artificial sports turf, and its performance determines the sports mechanics, sports safety and sports comfort of the lawn. At present, the main material used in artificial turf is polymer, which is due to the excellent physical, chemical and mechanical properties of polymer composite materials, such as light weight, high specific strength, large specific modulus, good corrosion resistance, convenient molding, etc. features. However, the surface hardness of polymer materials is low, the bearing capacity is poor, and it is easy to wear; while the artificial turf is frequently used and wears heavily, which makes the artificial turf prone to split ends, hair loss, a...
