Problem certainly.
Invention content
In order to solve the problems, such as that VOC releases are unable to reach national legislation requirement, this reality in existing flaxen fiber composite material
With the novel flaxen fiber for proposing the release of a kind of formaldehydeless and acetaldehyde, the size that wherein flaxen fiber 1 is formed is 5~10mm flaxen fibers
Absorbent particles 2 are filled in gap in group between flaxen fiber, and the fibre bundle of flaxen fiber 1 and absorbent particles 2 are mutually viscous
Even.
The preparation method of the flaxen fiber of described formaldehydeless and acetaldehyde release, is as follows：
1) flaxen fiber packet is opened into packet using bale opener, flaxen fiber is made to form the flaxen fiber group that size is 5~10mm；
2) above-mentioned flaxen fiber is rolled into a ball and is sprayed through adsorbent solution, flaxen fiber group is enable fully to infiltrate adsorbent solution to full
And state；
3) the flaxen fiber group of infiltration saturation is aerated gas exhaust treatment；
4) Negative pressure will be carried out in the flaxen fiber group transfer closed container of infiltration saturation, vacuum degree is 1~10kPa；
To the flaxen fiber of formaldehydeless and acetaldehyde release.
Wherein, the adsorbent is silane coupler modified nano clay.Flaxen fiber can select jute, flax, sword
Fiber crops, hemp or ramie harl.
Adsorbent suspension configuration method：By nanoclay, the 0.25- of the 0.5-2wt% of the flaxen fiber gross mass
The dispersant of 1wt%, the silane coupling agent of 1-2wt% are added to the water, and form nanoclay-coupling of a concentration of 10-30wt%
Agent suspension；The nanoclay-coupling agent suspension is stirred into 0.5-2h under 1000-1350rpm rotating speeds；By the nanometer
Clay-coupling agent suspension stirs 1.5-3h under 1700-2000rpm rotating speeds, forms the coupling agent mixed liquor of nanoclay.
The beneficial effects of the utility model：
By the flaxen fiber that the utility model method is handled there is good environmental protection, formaldehydeless acetaldehyde to discharge, is widely used.
The fields such as natural fiber enhancing polymer matrix composite, building reinforcing material are can be widely applied to, before there is good application
Scape is a kind of inexpensive, environment-friendly type natural fiber treatment process.
