Preparation Method.
The natural fiber enhancing polymer matrix composite felt material of heretofore described formaldehydeless and acetaldehyde release, the felt material by
6~10 layers of composite fibre laying 3 links to form felt body by fiber, and the composite fibre laying 3 is by natural ramie fiber and gathers
Fibres mixing is closed to be interwoven；Absorbent particles 2 are filled in the gap of natural ramie fiber and polymer fiber；It is described natural
Flaxen fiber is Chinese fiber crops, jute, flax, sisal hemp or ramie harl；Polymer can be polypropylene PP, poly- second for polymer fiber
Alkene PE, polycarbonate, nylon 6PA6, nylon66 fiber PA66 or polylactide (or polylactic acid) PLA.The adsorbent is silane
Coupling agent modified nano clay.
A kind of preparation method specific steps of the natural fiber enhancing polymer matrix composite felt material of formaldehydeless and acetaldehyde release
It is as follows：
1) natural ramie fiber and polymer fiber carry out shredding processing, respectively the natural ramie fiber and polymer after shredding
Fiber sprays adsorbent suspension；
2) natural ramie fiber after shredding and polymer fiber are fully mutually mixed, mutually mixed fine to natural fiber crops again in the process
Peacekeeping polymer fiber sprays adsorbent suspension；
3) by air-laid or combing lapping, composite fibre laying is formed, again to natural fiber crops in laid process
Fiber and polymer fiber spray adsorbent suspension；
4) consolidation process is pierced into the hand-manipulating of needle to composite fibre laying after stacking 6~10 layers of composite fibre laying, forms composite felt
Material.
Adsorbent suspension collocation method is as follows：By the nanoclay of the 0.5-2wt% of the flaxen fiber gross mass,
The dispersant of 0.25-1wt%, the silane coupling agent of 1-2wt% are added to the water, formed concentration be 10-30wt% nanoclay-
Coupling agent suspension；The nanoclay-coupling agent suspension is stirred into 0.5-2h under 1000-1350rpm rotating speeds；By described in
Nanoclay-coupling agent suspension stirs 1.5-3h under 1700-2000rpm rotating speeds, forms the coupling agent mixing of nanoclay
Liquid.
Beneficial effects of the present invention：
Natural fiber enhancing composite felt material produced by the present invention has good environmental protection, formaldehydeless, acetaldehyde release, quality
Gently, it is widely used.The fields such as automobile, rail vehicle, aerospace, building, decoration, packaging are can be widely applied to, are had good
Application prospect, be it is a kind of low cost, the low hydroformylation preparation process of environment-friendly type flaxen fiber composite material felt material.
