Innovative Method for the Production of Natural Long-fibre Filled Polypropylene Sheets for Different Applications (06 ES SERT 0GEE)
Popis:
A Spanish research centre from the plastics sector has developed an innovative processing method for production of natural long-fibre filled polypropylene sheets. The obtained sheets, which are very interesting due to their biodegradable nature & mechanical properties, can be used for different applications. The low temperature and the homogeneous feeding of fibres in the extrusion machine are its main features. They are interested in establishing a license or a technical cooperation agreement.
Nowadays natural fibres are used in the plastics sector for the reinforcement of thermoplastics, improving in this way their biodegradable nature and providing interesting mechanical properties.
However, it is known that natural fibres present some important problems during the processing, the most important one being the melting temperature. Natural fibres suffer strong degradation processing at 200ºC (this temperature being typical for polymeric material as polypropylene). This degradation implies loss of mechanical properties and smell production.
In order to solve these inconveniences a Spanish research centre has developed a new processing method.
By controlling compounding parameters, studying the screw design, and selecting the best formulation, the research centre has been able to reduce the melting temperatures needed for the polypropylene while degradation effects of the natural fibres have been avoided.
As a result they have obtained sheets with improved mechanical and thermal properties.
Another problem the research centre has faced when developing this new method is related with fibres feeding. The structure of natural fibres creates balls that are impossible to be fed automatically in an extruder machine, constant and homogeneous feeding being very difficult to achieve. The centre has solved this problem by adapting some existing technology.
The centre has worked with two different commercial natural fibres: kenaf and hemp, not previously treated (only washed and cut), and the process has been applied in a co-rotative twin-screw extruder machine (see picture).
Innovative Aspects:
The obtained NF/PP sheets are extruded, instead of injected, and don't receive any chemical treatment.
The sheets have better properties with comparison to those already existing, as the fibre is not crushed, it is a long fibre.
Innovative aspects are:
- The production of an extruded sheet based on natural fibres and polypropylene by extrusion instead of the traditional injection procedures in which the fibres are crushed.
- Compounding and extrusion are performed in only one step.
- The feeding of natural fibres in an extruder machine.
- Suitable formulation to obtain a material with improved properties, better than other similar materials present in the industry.
