Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of polypropylene composite material, particularly a kind of polypropylene/bacteria cellulose composite material and preparation method thereof.
Background technology
Polypropylene (iPP) is owing to having the premium propertiess such as fusing point is high, tensile strength is high, relative density is low, corrosion-resistant, become in existing five large resins for universal use and consume the fastest resin of rate of growth, be widely used in aerospace, electrically, the field such as automobile.Although polypropylene has the premium properties such as compound with regular structure, degree of crystallinity height, traditional polypropylene has impact property difference, and embrittlement temperature is high, waits very important shortcoming.So greatly limit its range of application to a certain extent.
Natural fiber Reinforced Polypropylene is the emphasis that Recent study work is paid close attention to.Although natural fiber has the advantages such as light weight, inexpensive, raw material is easy to get, and the intensity of in most of the cases compound system can meet general application requiring.But the ununiformity of natural fiber and greatly limit its application in polypropylene with the uncompatibility of matrix resin.
Bacteria cellulose (BC), although have identical molecular structure unit with natural plant fiber, compares with natural cellulose and has much distinctive character.As homogeneous in appearance structure, smooth surface; Degree of crystallinity, the polymerization degree are higher; Tensile strength, Young's modulus are high; Can artificial regulatory etc. when biosynthesizing.Based on above characteristic, bacteria cellulose and polypropylene composite materials, not only can possess the advantage of polypropylene/natural-fiber composite material, can make up again the deficiency of natural fiber, thus give polypropylene better mechanical property.
