Abstract

The invention discloses a composite material for melting and chemically modifying the backing plate of a chain rail of a light tank. The composite material is made of the following components in parts by weight and according to specific process steps: NR: 75-85 parts; SBR: 18-22 parts; HS-860: 18-22 parts; PL-90: 0.5-0.7 parts; carbon black: 50-56 parts; white carbon black: 4-6 parts; graphene: 0.8-1.2 parts; DOA: 5‑7 parts; ZnO: 2.5‑3.5 parts; SA: 1.5‑2.5 parts; 4020: 1.5‑2.5 parts; 4010NA: 1.5‑2.5 parts; rubber protective wax: 3‑4 parts; terpene phenolic resin: 2.5-3.5 parts; PEG-4000: 1.5-2.5 parts; CZ: 0.9-1.0 parts; S: 1-1.5 parts; DCPD: 1-2 parts; HVA-2: 0.8-1.2 parts; Combining the method with the mechanical melting modification process, the preparation has good ozone resistance, excellent wear resistance, good cold resistance, particularly outstanding anti-reversion performance, excellent tear resistance, and good resilience. Solvent resistant composite material.

Description

technical field [0001] The invention relates to a rubber-plastic composite modified material for military use, specifically a kind of modified natural rubber (NR) / styrene-butadiene rubber (SBR) and high styrene resin (HS-860 resin) by mechanical and temperature melting modification. (graphene / silica) for complex modified composites. It is used as a modification for the stringent requirements of the rubber lining material for the chain rail pads of light tanks and chain rail personnel carriers. Background technique [0002] The chain-rail vehicle is a vehicle that uses a chain-rail driving system instead of a wheel driving system. This kind of vehicle has less pressure on the ground unit, less sinking, and strong adhesion. For common chain-rail vehicles such as civilian crawler excavators and military tanks, one of the necessary components of the chain-rail mechanism is the rubber lining of the chain-rail backing plate. Chain track vehicles, especially military tanks, are g...
