The invention relates to a method for preparing a
cellulose filled
composite material and belongs to the technical field of
composite material preparation. The method comprises the following steps: weighing 1,000-1,100 weight parts of
raw material, namely
cellulose;
drying for 3 hours until the
mass percentage of water is less than 1 percent; weighing 60 to 80 weight parts of
polyolefin, 5 to 15 weight parts of
coupling agent, 5 to 15 weight parts of lubricating agent, 5 to 15 weight parts of
impact resistant modifier and 5 to 15 weight parts of dispersing agent; fully mixing raw materials, and
processing by using an extruder; and cooling by using a cooling tank,
cutting the material to have the required shape, and
drying. The prepared
composite material has high mechanical properties and
thermoplastic property. The composite material can be used for manufacturing various structural products; and the products have different shapes, such as office supplies, living goods (such as plastic basins,
doors and windows and rail fences), crossbeams, bearing building materials, electronic product insulating shells, parts in the automobile industry, and interior decoration parts in the
aviation industry.
