Abstract

Abstract:

Polyurethane (PU) foam reinforced by free-rising hemp stem powder (HSP) is prepared with polyols and polyaryl polymethylene isocyanate (PAPI). Water is used as a blowing agent. Effects of the HSP on the physical properties and bacteria inhibitive rate are studied. The results shows that rebound resilience, tensile strength and elongation at break increase with the increasing HSP content within a certain range. The 75% compression set and bacteria inhibitive increase with the HSP content. The composite foams with 15 phr HSP shows the optimum overall properties with density and the 75% compression set are less than 50 kg/m³ and 5%, respectively. Hardness and tensile strength reach 256.1 N and 124 kPa, and rebound resilience around 50%.

Key words: polyurethane (PU), hemp stem powder (HSP), chain slippery effect, bacteria inhibition
