Method for preparing plastic wood

Abstract

The invention relates to a kind of method to produce plastic timber with paddy husk or rice bran. It makes recycling PET, Polyethylene, Polypropylene or PVC as main, and adds other auxiliary agents, after producing grains with double screw rod extruding machine, cast or press them to produce various profiled material. By using the technology, we can produce construction material like timber, which is called plastic timber here. It can be processed into various needed timber shapes, and has good process ability. Its performance is better than natural timber. Its most outstanding advantage is its biodegradation ability and reproducibility that are incomparable by other strengthening materials.

Description

technical field

[0001] The invention relates to a method for preparing composite materials from plant fibers and thermoplastics, in particular to rice husk or rice bran, and recycled polyethylene terephthalate (PET) or polyethylene, polypropylene, polyvinyl chloride and other methods of producing a wood-like building material - "plastic lumber".

[0002] This new technology can recycle all kinds of plastic products, such as milk bottles, mineral water bottles and other waste items, after sorting and sorting, they are cleaned and broken into crumbs, and then prepared into "plastic wood". It can be processed into various desired wood shapes, has good machinability like natural wood, does not absorb water, does not expand, resists corrosion, does not crack, impacts, and wears, and its performance is better than natural wood. Wood, suitable for places in direct contact with soil or water, non-rotten, insect-proof, no chemical substances penetrate into the surrounding soil, no pol...
