Background technology
Present widely used polylactic acid substrate-shaped molding compound process units is all suppressed by polylactic acid film.Arranging layer by layer with PLA and textile type fiber of resulting polylactic acid substrate-shaped molding compound, polylactic acid substrate-shaped molding compound has huge potential use in auto industry and household electrical appliances industry.At present polylactic acid substrate-shaped molding compound having many uses in automotive upholstery is general.Present research concentrates in the polylactic acid film compacting mostly, because interpolation discontinuity in the powder-type PLA process and skewness seldom have manufacturer to adopt the powder-type PLA to produce polylactic acid substrate-shaped molding compound.But the powder-type PLA but has than better permeability of polylactic acid film and bigger specific area.So how can realize that the continuous production of powder-type polylactic acid substrate-shaped molding compound is vital.
In the research of polylactic acid substrate-shaped molding compound, a lot of documents have been mentioned the layered distribution and the pressing process of polylactic acid substrate-shaped molding compound, as:
Document Huda, M.S., Drzal, L.T., Mohanty, A.K., Misra, M..Composites Science andTechnology.2008,68,424-432 has adopted the method for compacting layer by layer of polylactic acid film and bluish dogbane fabric to make polylactic acid substrate-shaped molding compound, and he has adopted the method for the flaxen fiber surface being carried out etching processing and silane coupler processing, and has adopted general hot pressing formation process.
Document Ochi, S.Mechanics of Materials.2008,40,446-452 adopts the flaxen fiber material without the component and the place of production, also is that the hot pressing formation process by polylactic acid film and bluish dogbane fabric makes polylactic acid substrate-shaped molding compound.
But, the polylactic acid substrate-shaped molding compound shaped device of above-mentioned document, all be to adopt polylactic acid film to lay, adopt hot pressing formation process to make polylactic acid substrate-shaped molding compound, can only obtain the bigger polylactic acid substrate-shaped molding compound of interfloor distance, perhaps can not serialization production, need further optimize.
Summary of the invention
The object of the present invention is to provide a kind of powder continuous laying type polylactic acid substrate-shaped molding compound process units, to overcome the above-mentioned defective that prior art exists.
