Abrasion-resistant functional master batch for artificial yarns, method for preparing abrasion-resistant functional master batch and application thereof

Abstract

The invention belongs to the technical field of novel materials, and particularly relates to abrasion-resistant functional master batch for artificial yarns and a method for preparing the abrasion-resistant functional master batch. The abrasion-resistant functional master batch comprises grafting materials and catalyst materials. The grafting materials comprise, by weight, 70-99 parts of polyethylene resin, 0.01-10 parts of initiators, 1-10 parts of silane coupling agents and 0.01-10 parts of antioxidants, and the catalyst materials comprise, by weight, 80-99 parts of polyethylene resin, 0.1-10 parts of catalysts and 0.1-10 parts of antioxidants. The method includes preparing the grating materials and the catalyst materials by the aid of two-step processes; proportionally granulating the grafting materials and the catalyst materials by the aid of screw extruders; soaking granules in water bath at the certain temperatures for a certain time; drying the granules to obtain the abrasion-resistant functional master batch. The abrasion-resistant functional master batch and the method have the advantages that the abrasion-resistant functional master batch prepared by the aid of the method can be added into yarn matrixes, and accordingly the abrasion resistance, the strength, the tear resistance, the fatigue resistance and the like of yarn fibers can be obviously improved.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a functional masterbatch of artificial turf, and to a preparation method and application of the masterbatch. Background technique [0002] Artificial turf fiber is the core material of artificial sports turf, and its performance determines the mechanical properties, sports safety performance and sports comfort performance of sports turf. At present, the main material of artificial grass fiber is polymer, which has excellent physical and chemical properties, but also has low surface hardness and low load-bearing capacity. Under the condition of high-intensity and high-frequency use, it is easy to wear, and the grass will split and tear. Such phenomena are likely to cause danger and are not conducive to the development of major competitions. Therefore, wear resistance has become one of the most important indicators for evaluating the quality of artificial turf, and it is the...

Problems solved by technology

[0003] Based on the research on the wear resistance of artificial grass, it mainly focuses on the modification of grass raw materials and the change of grass shape. For example, patent application CN101476174A and patent application CN102493011A increase the strength of grass by adding inorganic rigid particles, but the inorganic particles are agglomerated The phenomenon is serious, resulting in uneven dispersion in the matrix resin, which leads to an increase in the wear rate of the grass filaments, greatly reducing the wear performance and stability of the sports lawn

The patent application CN105019333A prepares the grass silk into an S shape, and the contact area increases, which plays a role in buffering and dispersing the pressure to a certain extent. However, due to the large contact area and the smooth surface of the grass silk, the friction coefficient is small. It is easy to slip and fall, so it is not conducive to the development of sports and reduces the safety performance of the lawn
