Abstract
A kind of wood chip, red mud modified plastics mixture, each components by weight is the used heat thermoplastic plastic in the mixture: wood chip: red mud=20-50: 15-65: 15-65.The method characteristics of manufacturing modified plastics provided by the invention are that production cost is low, and the plastic hybrid after the modification is easy to molded and shaped, its product strength height, and water resistance is good, and surface detail is attractive in appearance.
Description
The invention relates to reclaiming and utilizing waste plastics.
Along with being extensive use of of plastics, various plastic waste materials are increasing, and wherein a large amount of is various thermoplastic articles.Recycle these waste or used plastics, make it replacing wood and be applied, can relax the situation of wood supply anxiety, can solve the pollution of plastic refuse again environment in fields such as furniture manufacturing, building, communications and transportation.
At present, a large amount of sawdust fiberboard undercapacities that use, water resistance is poor, in case surface protecting layer is destroyed, the sawdust of nexine can be scattered by nature.
The method that the object of the present invention is to provide a kind of technics of reclaim of plastic waste to utilize according to the sheet material that method provided by the invention is made, has overcome the intensity of sawdust fiberboard and the shortcoming of water resistance difference.
The present invention realizes by following steps: bag, jar, container, the apparatus the like waste of selecting thermoplasticss such as polyvinyl chloride, polyethylene, polypropylene, polystyrene, polyethylene terephthalate to make, use crusher or scissors are with its fragmentation or cut into～1mm
2Fragment, the fusion particle diameter is less than 2mm
3Dried wood chips and dry powdery red mud, be the used heat thermoplastic plastic by the weight ratio of each component: wood chip: red mud=20～50: 15～65: 15～65.The mixture that fusion is good adds in the hopper of screw extrusion press, regulates barrel temperature and extruded velocity, makes just fusion of plastics, and wood chip, red mud are bonded together, and promptly makes wood chip of the present invention, red mud modified plastics.
Embodiment one
Bag, jar, container, the apparatus the like waste of selecting thermoplasticss such as polyvinyl chloride, polyethylene, polypropylene, polystyrene, polyethylene terephthalate to make, use crusher or scissors are with its fragmentation or cut into～1mm
2Fragment, get plastic flakes 20Kg, add particle diameter less than 2mm
3Dried wood chips 15Kg, dry powdery red mud 65Kg mixes, and after screw extrusion press processing, promptly makes wood chip of the present invention, red mud modified plastics.
Embodiment two
Get above-mentioned used heat thermoplastic plastic, wood chip and red mud and be respectively 50Kg, 30Kg and 20Kg, make wood chip of the present invention, red mud modified plastics according to the method for embodiment one.
Embodiment three
Get above-mentioned used heat thermoplastic plastic, wood chip and red mud and be respectively 20Kg, 65Kg and 15Kg, make wood chip of the present invention, red mud modified plastics according to the method for embodiment one.
Embodiment four
Get above-mentioned used heat thermoplastic plastic, wood chip and red mud and be respectively 20Kg, 30Kg and 50Kg, make wood chip of the present invention, red mud modified plastics according to the method for embodiment one.After the moulding, survey its performance and be: hardness (micro-) 100～110; Bending elastic modulus 54.8GPa; Flexural strength 236MPa; Shock strength 8.9KJ/m
2
The method characteristic of manufacturing modified plastics provided by the invention is that production cost is low, and the plastic hybrid after the modification is easy to molded and shaped, its product strength height, and water resistance is good, and surface detail is attractive in appearance. The various sheet materials that are pressed into by this modified plastics can replace timber to be widely used in making stool, chair, tea table, combination sideboard etc.
