Problems solved by technology

And artificial turf is used for a long time, it will also leave a variety of bacteria, as time goes by, it is not conducive to human health
Therefore, it will be an important development trend to make artificial turf have antibacterial effect; to obtain turf with antibacterial effect, antibacterial materials can be added to artificial grass raw materials; however, the addition of antibacterial materials will also lead to artificial grass. The decline in other processing properties such as performance will lead to a decline in the quality of the artificial grass product itself

Abstract

The invention discloses an antibacterial master batch, a preparation method of the master batch, antibacterial artificial grass and a preparation method of the artificial grass. The antibacterial master batch is prepared by the step of performing double screw co-extrusion on the following components in percentage by weight: 20-30 percent of low-density polyethylene, 30-40 percent of an antibacterial material, 10-20 percent of a plasticizer, 10-20 percent of acetone and 10-20 percent of polyphthalamide (PPA). The method for preparing the antibacterial artificial grass comprises the following steps: adding the antibacterial master batch disclosed by the invention into a matrix resin, mixing, extruding, stretching, setting, dropping and twisting. The antibacterial material, the low-density polyethylene and PPA are co-extruded to process the antibacterial master batch, so that the tensile strength, deflection and other performances of the artificial grass can be improved; and moreover, the antibacterial artificial grass disclosed by the invention is subjected to hot extrusion in a spinning screw, so that the antibacterial master batch and the matrix resin are fused and therefore the antibacterial artificial grass has resistance and good processability.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an antibacterial masterbatch and a preparation method thereof, and an antibacterial artificial grass and a preparation method thereof. Background technique [0002] Artificial turf is a non-living plastic chemical fiber as raw material, artificially manufactured imitation ecological turf, it does not need to consume the necessary fertilizer, water and other resources for growth like natural turf, maintenance is simple, and can meet the needs of all-weather high-intensity sports . Restricted by environmental conditions or other factors, it is inconvenient to lay natural lawns in many places. Artificial grass overcomes several major difficulties of natural grass: first, it cannot grow under extreme climatic conditions; second, some countries and regions cannot pay high maintenance costs due to economic reasons; third, it can be used in some covered sports venues Cannot ...
