Embodiment 1

[0088] According to the mass percentage, 30% SBS elastomer (Li Changrong chemical industry, 3546), 40% thermoplastic polyurethane elastomer (1565IC), 27% calcium carbonate (10um), 1.5% grass green color masterbatch WHC-GM1011 and 1.5% % UV-resistant additives (UV-327) are mixed well. Put the mixed composition in Melt and blend in a co-rotating twin-screw extruder, the blending temperature is 180-200 ° C, the extruded splines are cooled by water, air-dried, and pelletized to obtain cylindrical pellets with four quadrilateral grooves, with a particle diameter of 2 mm and a length of 2 mm. 3mm, bulk density 0.45g / cm 3 . After the pellets were dried at 90° C. for 2 h, test samples were prepared and their relevant properties were tested as shown in Table 1.

Embodiment 2

[0090] According to mass percentage, 40% SEBS elastomer (U.S. Kraton, G1651), 25% naphthenic oil (4010), 20% thermoplastic polyurethane elastomer (8170RV), 12.5% ​​calcium carbonate (10um), 2 % of grass green color masterbatch WHC-GM1011 and 0.5% of UV-resistant additives (UV-327) are mixed evenly. Put the mixed composition in Melt and blend in a co-rotating twin-screw extruder, the blending temperature is 180-200 ° C, the extruded splines are cooled by water, air-dried, and pelletized to obtain four cylindrical pellets with round holes and grooves, with a particle diameter of 3 mm and a length of 3 mm. 5mm, bulk density 0.3g / cm 3 . After the pellets were dried at 90° C. for 2 h, test samples were prepared and their relevant properties were tested as shown in Table 1.

Embodiment 3

[0092] According to the mass percentage, 40% SBS elastomer (Li Changrong chemical industry, 3546), 8% thermoplastic resin PE, 30% thermoplastic polyurethane elastomer (1560IC), 20% nano calcium carbonate (50nm), 1% grass Green color masterbatch WHC-GM1011 and 1% UV-resistant additive (UV-327) are mixed evenly. Put the mixed composition in Melt and blend in a co-rotating twin-screw extruder, the blending temperature is 180-200 ° C, the extruded splines are cooled by water, air-dried, and pelletized to obtain solid cylindrical pellets with a particle diameter of 2 mm, a length of 3 mm, and a bulk density of 0.60 g / cm 3 . After the pellets were dried at 90° C. for 2 h, test samples were prepared and their relevant properties were tested as shown in Table 1.

Abstract

The invention relates to an environment-friendly artificial turf filling thermoplastic elastomer particle and a preparation method thereof. The raw material for preparing it comprises the following components in mass content, (A) 30%-70% thermoplastic material, (B) 0-25% mineral oil, (C) 10%-40% thermoplastic polyurethane elastomer, (D) 10%-50% of inorganic fillers, (E) 0.1%-3% of UV-resistant additives, (F) 0.5%-6% of color master particles or toners, based on the total mass of each component. The composition pellets are obtained by melting and blending each component in a certain proportion. The thermoplastic elastomer pellets can be recycled, environmentally friendly, pollution-free, significantly improved in resilience and wear resistance, and colorful in color; the pellets are easy to produce and the shape can be adjusted. , the packing density is low.

Description

technical field [0001] The invention relates to an environment-friendly artificial turf filling thermoplastic elastomer particle and a preparation method thereof, in particular to a thermoplastic polyurethane elastomer-containing thermoplastic elastomer particle with high resilience and a preparation method thereof, belonging to the research field of polymer materials. Background technique [0002] Artificial turf is widely used in sports and landscaping fields. Due to its excellent mechanical properties, low maintenance costs, and little influence from the environment, weather and region, natural turf has incomparable advantages. In recent years, its market has grown by more than 20% annually. rate increases. [0003] Artificial turf generally consists of four layers: grass fiber, filling layer, backing and foundation. The filling layer is currently mainly filled with rubber particles, and its main functions are: on the one hand, it can keep the grass silk upright; on the ...
