Abstract

The invention provides ionic liquid and a method for a homogeneous phase-modified reed-reinforced PE (polyethylene) composite material thereof, which belong to the field of synthesis and modification of materials. The ionic liquid is 1-vinyl-3-hydroxyethyl imidazole chlorine which is synthesized by N-vinyl imidazole and 2-chlorohydrin as raw materials according to the molar ratio of (1 to 1.5):1; the method adopts the ionic liquid, namely (1-vinyl-3-hydroxyethyl imidazole chlorine) to perform homogeneous phase modification on reeds, and the homogeneous phase-modified reed and PE are compounded, so that the homogeneous phase-modified reed-reinforced PE composite material is prepared. The ionic liquid designed by the invention can be used for effectively decreasing the surface polarity of the reeds, and increasing the dissolving capability of reed fibers. Compared with conventional methods, the method for performing homogeneous phase modification on the reeds by adopting the ionic liquid has the advantages of environment-friendly reaction solvents and recyclability; moreover, the homogeneous phase modification method improves the compatibility between the reeds and the PE, and the prepared homogeneous phase-modified reed-reinforced PE composite material has good mechanical property and excellent processability.

Description

technical field

[0001] The invention belongs to the field of material synthesis and modification, and specifically relates to synthesizing a recyclable ionic liquid, and using the ionic liquid as a solvent to homogeneously modify reeds, and to apply homogeneously modified reeds to PE to prepare homogeneously modified Reed / PE composite material. Background technique

[0002] Plant fiber is the most abundant natural polymer in nature, and the preparation of plant fiber / thermoplastic resin composites by blending technology is a new way to effectively develop and utilize this kind of renewable resources. Reed is a kind of natural plant fiber, which has the advantages of high yield, low requirement for growth environment and short growth cycle. Cellulose is the main component of reed. Due to the presence of a large number of hydroxyl groups in its structure, the reed fiber has strong polarity, which makes the interface wettability and interface adhesion between it and non-polar ...
