Graft reaction；The mass ratio of glyoxal and chitosan is 1：4-1：5；
C. the aramid fiber for completing graft reaction is washed, dried.
Further, the aramid fiber slurry is prepared using meta-aramid pulp, and specific preparation process is as follows：
Meta-aramid pulp is subjected to Low Temperature Plasma Treating first, gas is argon gas, processing power 40-50W, pressure
Strong 50-80Pa, minute time 3-5, then add water, polyethylene glycol and emulsifier op-10 that solution, simultaneously is made meta-aramid pulp
After grinding 1-3 hours with colloid mill, aramid fiber slurry is made；In aramid fiber slurry, the pulp of meta-aramid containing 5-10wt%, 0.2-1
Wt% polyethylene glycol, 1-2wt% emulsifier op-10s, remaining composition are water.
Meta-aramid pulp is after Low Temperature Plasma Treating, the work of the molecule of fiber surface in meta-aramid pulp
Property improve, be then made the aqueous solution jointly with polyethylene glycol and emulsifier op-10, blend compounds body mill is ground, with further
Make the fiber in meta-aramid pulp that fibrillation occur, increase the specific surface area of the fiber in meta-aramid pulp, by grinding
Stable suspension is formed afterwards, is advantageous to aramid fiber and is impregnated, and meta-aramid pulp is uniformly coated on aramid fiber fibre
The surface of dimension.
Further, after the meta-aramid pulp is the sieved through sieve using 150 mesh, the part of sieving is taken.Meta-aramid
When the fiber of pulp is shorter, its specific surface area is also larger, has more active groups, is advantageous to strengthen aramid fiber and matrix
The caking property of resin.
Further, in step a, when aramid fiber carries out Low Temperature Plasma Treating, gas is argon gas, processing power is
250-300W, pressure 50-60Pa, minute time 10-15.In step a, dipping temperature of the aramid fiber in aramid fiber slurry is
70-80℃。
Further, the concentration of chitosan is 10-20g/L in the step b.The time of graft reaction is in the step b
0.5-1.5 hours, reaction temperature are 5-10 DEG C.
Further, in step c, the temperature of washing is 40-60 DEG C, and the temperature of drying is 50-70 DEG C.
After carrying out surface graft modification to aramid fiber using the present invention, the work of the molecule on the surface of aramid fiber can be strengthened
Property, in modifying process, first by the surface of the fibre grafting in Fanglun slurry cake to aramid fiber, in glyoxal and the water of chitosan
In solution, in the presence of glyoxal, the functional group on chitosan is connected with each other, and netted knot is formed on the surface of aramid fiber
Structure, strengthen the adhesion of the fiber and aramid fiber in Fanglun slurry cake.Aramid fiber by the present invention carry out graft modification after, its
It is greatly improved with the cohesive force of matrix resin, compared with not carrying out the aramid fiber of graft modification, prepared is compound
The tensile strength of material averagely improves 32%, and highest improves 35%.
