Abstract
The invention relates to a paper sludge-polyolefin type composite sectional bar and a preparation method thereof, belonging to the technical field of materials. The paper sludge-polyolefin type composite sectional bar comprises the following materials in percentage by weight: 20-60% of polyolefin, 30-70% of paper sludge, 0.5-5% of lubricant, 0-5% of compatilizer, 0.5-3% of ultraviolet light absorber and 0.5-5% of pigment. By introducing the compatilizer, fibers in the paper sludge are uniformly distributed in the composite sectional bar, and the binding force between the fibers and a plastic matrix is improved, so that the fibers play a role in reinforcing phases in the composite sectional bar, thus the impact resistance and toughness of the composite sectional bar are improved, and meanwhile, the strength of the composite sectional bar is further improved.
Description
Technical field
The present invention relates to a kind of paper mill sludge-polyolefin-type composite material and preparation method thereof, belong to material technology field.
Background technology
Paper mill sludge be the paper waste that produces of paper mill after environmental protection equipment is processed, the mud producing in settling tank.In the composition of paper mill sludge, ash rate is larger, generally can reach 50%--70%, contains a large amount of fibers simultaneously.The utilization of paper mill sludge is except a part of as fertilizer sources is utilized at present, and most processing mode is landfill or burning.Such processing mode has been wasted land resources on the one hand, also can produce secondary pollution simultaneously.In laboratory, have paper mill sludge and polyethylene are prepared to matrix material, technique is to adopt highly basic that the fibre composition in paper mill sludge is decomposed, and uses the inorganic components in paper mill sludge.There is major defect in this method: adopt highly basic cleaning charge with high, the time is long, cannot realize industrialization; In the waste water of cleaning paper mill sludge, owing to there being residual highly basic, environment is caused to secondary pollution; The fiber reality washing has played enhancement for matrix material, has wasted resource.
Summary of the invention
The technical problem to be solved in the present invention is for the composition of paper mill sludge and feature, develops the modification of paper mill sludge and utilizes technology, adopts recovery polyolefine and paper mill sludge to carry out the outdoor section bar of compound preparation, has improved the utility value of product.
The present invention is technical solution problem by the following technical programs, and a kind of paper mill sludge-polyolefin-type composite material is comprised of the material of following weight percent:
In said components, described paper mill sludge is the mud that paper waste produces after treatment.
Described polyolefine comprises a kind of in PE, PP new or that reclaim and PVC.
Described lubricant is stearic acid or stearate lubricant.
Described compatilizer is Polyolefin Grafted Maleic Anhydride class compatilizer.
The preparation method who the present invention further provides paper mill sludge-polyolefin-type composite material, comprises the following steps:
Step 1, batch mixing, in described ratio, add polyolefine, paper mill sludge, lubricant, compatilizer, UV light absorber, pigment in mixer, to be tentatively mixed to get section bar compound;
Step 2, mixing extrusion, add described compound in twin screw extruder, to carry out mixingly, then extruded by mould;
Step 3, cutting, press desired length cutting by extrusion profile, gets product.Wherein, the extrusion temperature of described step 2 is 100-230 ℃.
In paper mill sludge, main component is ash content and the fiber with certain length-to-diameter ratio.A large amount of ash contents can improve rigidity and the intensity of composite material, but have reduced anti-impact agent performance and the toughness of composite material simultaneously.
The present invention is by the introducing of compatilizer, fiber in paper mill sludge is evenly distributed in composite material, and improved the bonding force of fiber and plastic substrate, thereby make fiber in composite material, play the effect of wild phase, not only improve anti-impact agent performance and the toughness of composite material, further improved the intensity of composite material simultaneously.
