Study on the Acrylic Resin Coating Agent Modified by Nanocrystalline Cellulose

Abstract:

In this paper, nanocrystalline cellulose (NCC) was prepared from bleached aspen kraft pulp by the method of sulfuric acid hydrolysis. The morphology and the size of NCC were characterized by atomic force microscopy(AFM) and X-ray diffraction(XRD). The acrylic resin /NCC composite was prepared by physical blends of acrylic resin and NCC. The physical-mechanical properties of the film from acrylic resin /NCC composite were measured . The results show that the resulting NCC has a rigid rod-shape structure with crystallinity of more than 80%, 26.51 nm in diameter and 200―400 nm in length. The dosage of NCC has important influnce on the physical-mechnical properties of the film from acrylic resin /NCC composite. The tensile strength, the moisture permeability and water absorption of the film increase with the dosage of NCC notably, the elongation at break of the resulting film decreases compared to the control sample..
