Effect of aluminosilicate on flame-retardant and mechanical properties of lignocellulose composite

Functionalized lignocellulose (LC) wrapped with aluminosilicate was fabricated via a facial mechanical grinding assisted hot-pressing method, which used for flame retardant composite. The aluminosilicate particles with an average size of 3 μm were distributed on the lignocellulose surface by hydrogen bonds and viscous polyacrylamide (PAM). The as-prepared aluminosilicate-PAM/lignocellulose (A-PAM/LC) composite exhibited the excellent flame-retardancy and mechanical properties. The thermal decomposition of A-PAM/LC composite delayed by 31 °C as the aluminosilicate was loaded. The heat release rate (HRR) and total heat release (THR) of A-PAM/LC composite was reduced by 20.6 and 41.1%, respectively. Meanwhile, the A-PAM/LC composite showed the maximum bending strength of 34.23 ± 1.52 MPa and increased by 67.3% compared to the PAM/LC composite.
