Abstract

The invention discloses a modified floating bead / graphene oxide flame-retardant runway particle material and a preparation method thereof. The material comprises the following raw materials in parts by weight: 100 parts of a rubber-plastic elastomer, 10-50 parts of a compound flame retardant, 5-12 parts of naphthenic oil, 5-10 parts of superfine white carbon black, 3-5 parts of slaked lime, 1-2 parts of zinc stearate, 100-130 parts of calcium carbonate and 0.5 part of plastic toner; and the mass ratio of modified floating beads to graphene oxide in the compound flame retardant is (1-5): 1. Theprepared modified floating bead / graphene oxide flame-retardant runway particle material has the characteristics of good flame-retardant effect, aging resistance, high tensile strength and the like, and is wide in application prospect and huge in market demand.

Description

technical field [0001] The invention belongs to the technical field of plastic runways, and in particular relates to a modified floating bead / graphene oxide flame-retardant runway granular material and a preparation method thereof. Background technique [0002] The plastic runway is an indispensable and important facility in modern track and field venues, and has been designated by the International Olympic Committee as one of the necessary conditions for international competition venues. Compared with the traditional soil runway, it has good elasticity, skid resistance, wear resistance, shock absorption, easy site maintenance, bright colors, beautiful and tidy. In view of the above advantages, the plastic track was quickly adopted by various track and field venues soon after it came out. However, runway granules are flammable materials, which are easy to cause fire during use and pose a great threat to people's property and personal safety. Therefore, it is imperative to f...
