AI Technical Summary
Technical Problem
The composite material of rapeseed straw and polyvinyl chloride is easily damaged during friction and wear, and the interface debonding phenomenon is serious, which leads to surface wear and structural damage, limiting its application range.
Method used
The rapeseed straw was coated with an elastomer layer and a self-lubricating layer of nano-graphite particles using a coating method. Combined with microwave treatment, high-pressure homogenization and ultrasonic treatment, an elastomer buffer layer and a self-lubricating layer were formed, which were then cured by vacuum hot pressing.
Benefits of technology
It improves the wear resistance and service life of materials, expands their application range, reduces wear and maintenance costs, and achieves a self-lubricating effect.
