Embodiment 1

[0026] 1) Prepolymer preparation

[0027] First connect the oil bath, three-necked flask, condenser tube, and vacuum pump from left to right, and then check whether the air tightness is good. After installing the instrument, 30g conductive carbon black, 40g antimony trioxide, 30g decabromodiphenyl ether are dried and crushed, then mixed with 1000g polytetrahydrofuran ether glycol (PTMG) at 40-50℃ temperature Then use a thermal shearing machine at 3000-4000r / min speed for 10-15min into a homogeneous phase, then stir and dehydrate for 3h under 110℃, -0.096MPa vacuum conditions, cool to 60℃, and quickly mix with 180g diisocyanate The temperature is naturally raised to 85°C for heat preservation, and the reaction is carried out for 2 hours under the protection of nitrogen. After 10 minutes of vacuum degassing, the polyurethane prepolymer is obtained and sealed and stored for later use.

Embodiment 2

[0033] 1) Same as Example 1

[0034] 2) Preparation of aramid fiber skeleton material

[0035] Use silane coupling agent to activate the surface of high-strength, high-modulus aramid fiber to avoid delamination of aramid fiber and matrix material to improve the bonding strength with matrix resin. Then the treated aramid fiber is wound around the mold for 10 times in a whole rope-like way of winding an endless belt.

Embodiment 3

[0038] 1) Same as Example 1

[0039] 2) Preparation of aramid fiber skeleton material

[0040] Use silane coupling agent to activate the surface of high-strength, high-modulus aramid fiber to avoid delamination of aramid fiber and matrix material to improve the bonding strength with matrix resin. Then, the treated aramid fiber is wound on the mold in a whole rope-like way of winding an endless belt for 8 times.

Abstract

The invention relates to a robot track and a preparation method thereof, in particular to a casting polyurethane robot track with a framework made of aramid fiber and a preparation method thereof. High-strength aramid fiber or polyamide fiber is introduced as the framework in a track strong layer. A polyurethane elastomer is used as an overall casting layer in the robot track. When the casting polyurethane robot track with the framework made of the aramid fiber is prepared, a whole rope-shaped annular belt winding mode is adopted. The track polyurethane elastomer is made of polymer polyalcohol, polyisocyanate, a catalyst, a chain extender and a reinforcing agent. The aramid fiber is adopted as the material of the framework of the robot track, and the casting polyurethane elastomer is adopted as the carcass material of the robot track, so that the defects in all aspects of an existing metal track and a rubber track are overcome, the quality stability of the robot track is improved, and the service life of the robot track is prolonged. The preparation technology is simple, and production is easy.

Description

Technical field [0001] The invention relates to a robot crawler and a preparation method thereof, in particular to a pouring polyurethane robot crawler with aramid fiber as a skeleton and a preparation method thereof. Background technique [0002] Now mobile robots have been widely used in various fields, including anti-terrorism and anti-riot, emergency rescue, polar detection, power facility inspection and maintenance, and nuclear radiation detection. Mobile robots must often work in various complex extreme environments (high and low temperature, , Ultra-high pressure, nuclear radiation, etc.) and various terrains (soft and hard ground, tidal flats, grasslands, trenches, etc.). The walking mechanism of the robot, which is required to have good adaptability and flexibility to overcome the instability of the environment, is a necessary guarantee. At present, the robot walking mechanism is mainly divided into wheel type, leg type, crawler type, composite type (such as wheel leg t...
