The effect of pipe mixing dispersion and the intensity of connection, dispersibility and compatibility in the fibre are also obviously improved, and promote the resistance to of fiber
Corrosivity and intensity.
The acid and alkali-resistance polymer fiber material preparation method the following steps are included:
(1), raw material mixes: modification of chitosan and pretreatment carbon nanotube being mixed, mixture can increase the intensity of fiber and resistance to
Acid-base property makes fiber not decompose or be carbonized when being in high temperature, is able to maintain the shape of fiber, and modification of chitosan weight is added
Nano-titanium dioxide is added using ultrasonic oscillation 20min in the deionized water of amount 62 ~ 64%, is uniformly mixed, and glycidol is added
Esters epoxy resin and 1 times of glycidyl ester epoxy resin weight of dehydrated alcohol, after being heated to 50 ~ 55 DEG C, insulated and stirred
30 ~ 40 minutes, deaeration obtained spinning solution；
(2), spinning is washed: spinning solution being sent into spinning machine and carries out wet spinning, coagulating bath is alkaline ethanol solution, takes out and spins
It is rinsed through deionized water to neutrality after silk, obtains as-spun fibre；Ensure the fiber number of fiber, be conducive to production,
(3) dry: as-spun fibre being placed in baking oven and is dried, temperature is 23 ~ 25 DEG C, and uitraviolet intensity is 1500 μ W/
cm2, obtain the textile fabric of high strength acid resistant caustic corrosion.The flexibility and fibre strength of fiber can be increased.
The intermittent irradiation of the ultraviolet light, exposure intensity are 2200 μ W/cm2, 10min is irradiated, 15min is stopped.
2mol/L hydrogen is added in 68 ~ 72% alcoholic solution to volume fraction in the alkaline ethanol solution of the step (2)
Sodium hydroxide solution, the pH for being adjusted to alcoholic solution is 9.4 ~ 9.8.
Wet spinning in the step (2), spinneret 5 ~ 7m/min of speed, stretch bath temperature by 10 ~ 25 DEG C of coagulation bath temperature
45 ~ 50 DEG C, 4 ~ 5m/min of draft speed.
Fibre number is 85-110dtex.
Fiber in the application can be used for preparing pipeline corrosion protection cloth, special working suit, acid and alkali-resistance gloves etc..
The invention has the advantages that the textile fabric of high strength acid resistant caustic corrosion provided by the invention, is added into chitosan
Sodium selenite solution carries out vacuum rotating after being gradually heated up, and carries out the intermittent irradiation of ultraviolet light, promotes selenium and amino of chitosan
In conjunction with being finally freeze-dried, remove extra moisture, make blocky Chitosan powder, increase amino of chitosan and selenium
Binding ability increases the stability of modification of chitosan, increases the flexibility and caking property of chitosan,；By modification of chitosan and carbon
Nanotube mixing, increases the flame retardant property of fiber, makes fiber that burning will not occur when being in 200 DEG C, decompose or be carbonized, Neng Goubao
It holds and apparent deformation does not occur, carbon nanotube is by being modified, and dispersion effect and the performance in conjunction with chitosan are obviously improved, carbon
The porous structure of nanotube can closely be connect with modification of chitosan, can be played significant humidification, be avoided use process
