Formation of the structure and properties of highly filled polymer composite materials with a deformable disperse filler

Abstract

The paper discusses the main patterns of structure formation and the production of highly filled polymer composite materials based on a deformable particulate filler from rice straw (agricultural waste) and a dispersion of polyvinyl acetate (PVA) in water. t has been established that when using a deformable filler of rice straw powder, it is possible to obtain under high pressure (up to ~230 MPa) pressing DFPCM with the highly-filled type of structure and the content of dispersed filler up to ~90% by volume. Such PCM has a sufficiently high level of physical and mechanical characteristics - compressive strength ~104 MPa and elastic modulus ~ 3.0 GPa, which opens up opportunities for its wide application and production of products for various purposes from "green chemistry" materials.
