At present, to improve the water imbibition and the shortcoming low with thermoplastic resin interface bond strength of bamboo fibre, adopt mostly
Bamboo fiber is modified with the chemical method including etherificate, esterification, grafting, copolyreaction, to pass through substituent
Introducing destruction cellulosic molecule between interaction in reduce the crystallinity of cellulose and the polarity of cellulosic molecule.So
And, cause the characteristics of cellulose high crystalline most chemical modifications to be difficult to obtain good effect, such as CN104313877A is used
Silane coupler modified bamboo fibre, CN102952337B uses titanate coupling agent modified bamboo fibre, because cellulose is highly crystalline
The characteristics of property and be unable to reach preferable modified effect.In addition, after the chemical modification, residual modifying agent is often difficult to remove,
So as to which the following process to fiber causes difficulty, such as《Injection-molded short hemp fiber/glass
fiber-reinforced polypropylene hybrid composites-Mechanical,water absorption
and thermal properties》(Journal ofapplied polymer science,2007,103(4),2432-
2441) acetylation process mentioned in, the acidity of residual monomer and the acidity of catalyst make it during machine-shaping
There is very strong corrosivity to equipment, even if by subsequent treatment, still having the absorption of partially acidic catalyst residual in the product；
Etherification modified aspect, such as exists《The study on the modification of bamboo fibre Benzylation》(Sun Jinyu, Wang Xixi, Xu Lei, biomass chemistry work
Journey, 2007,4 (41)：35~38) in use benzyl chloride for inorganic agent be modified bamboo fibre, but benzyl chloride it is poisonous and presence not exclusively
React and produce the risk of residual so that its economy is had a greatly reduced quality with practicality.
The content of the invention
