Method for processing foamed aging-resistant plastics for artificial turf filling

Abstract

The invention discloses a method for processing foamed aging-resistant plastics for artificial turf filling. The method comprises the following steps: 1, performing melt mixing on polymers on an opentype plastic mixing mill, and respectively adding the following components in parts by mass for melt mixing: 110 parts of polymers, 3-11 parts of a foaming agent, 2-5 parts of a blowing promoter, 0.15-0.45 part of a chemical modifier and 30 parts of a filling material; and 2, adding the mixture into a press vulcanizer after cooling, performing mold foaming at a temperature of 160-250 DEG C, discharging, and crushing, thereby obtaining foamed modified plastic particles. The invention provides a processing method capable of producing foamed aging-resistant plastics with advantages of low density, excellent thermal insulation property, low construction cost and a certain water through performance for artificial turf filling.

Description

technical field [0001] The invention belongs to the field of polymer materials, in particular to a method for processing foamed plastics for aging-resistant artificial turf filling. Background technique [0002] In recent years, a variety of environmentally friendly artificial turf for sports made of thermoplastic rubber filling particles has appeared on the market, but there are artificial turf filling particle systems that are expensive to build, high in bulk density, lack of elasticity for long-term use, and poor aging resistance. Moreover, it is easy to float on the surface of the lawn after being soaked in rainwater, so that the filling particles are easy to swim, and the distribution in the lawn is uneven. [0003] The filling particles of the lawn should maintain good treading performance, not easy to float after being soaked in water, and at the same time, the density should be as low as possible, which helps to reduce the cost of materials.
