Embodiment 1

[0033] A) The raw materials PP, PS (PS / PP=2.5%) and the auxiliary antioxidant 4010 with a mass fraction of 0.02% are pelletized in a twin-screw extruder.

[0034] B) The PP blended pellets obtained in step A) are sent from the hopper 1 to the screw extruder 2 of the melt blown spinning machine for melt extrusion. The temperature of screw one zone, two zone, three zone is respectively set to 175 ℃, 190 ℃, 225 ℃, adjust screw speed to be 40rpm, after material is fully melted, send into filter system 3, here the impurity in the material (such as carbon, ash, etc.), the material enters the metering pump 5 through the melt pipe 4, and the temperature of the metering pump 5 is kept at about 240° C., and the speed is 30 rpm. The melt then passes through the distribution pipeline 6 and is spun in the spinning chamber 8. The filaments spun out of the spinning assembly 7 pass through the cooling window 9 to form primary crystalline filaments. The temperature of the hot air is set at 320...

Embodiment 2

[0037]A) The raw materials PP, PS (PS / PP=5%) and the auxiliary antioxidant 4010 with a mass fraction of 0.02% are pelletized in a twin-screw extruder.

[0038] B) The blended pellets of PS / PP=5% obtained in step A) are sent from the hopper 1 to the screw extruder 2 of the melt blown spinning machine for melt extrusion. Other processes and processing conditions are the same as B) of embodiment 1. The average diameter of the obtained fiber material is 4um (randomly sampled, and the average value of 20 fibers is counted by scanning electron microscope).

[0039] The prepared PS / PP blended melt-blown fiber material was placed in the simulated device of underwater benzene series ( figure 2 ), the simulation device for benzene series on the water surface ( figure 1 ) and deionized water to test the adsorption rate, see Table 3., and compare it with the PP melt-blown fiber material. From the comparison of the data in Tables 1 and 3, it can be seen that the adsorption ratio of PS / ...

[0042] B) The blended pellets of PS / PP=10% obtained in step A) are sent from the hopper 1 to the screw extruder 2 of the melt blown spinning machine for melt extrusion. Other processing and processing conditions are identical with embodiment 1. The average diameter of the obtained fiber material is 4um (randomly sampled, and the average value of 20 fibers is counted by scanning electron microscope).

[0043] The prepared PS / PP blended melt-blown fiber material was placed in the simulated device of underwater benzene series ( figure 2 ), the simulation device for benzene series on the water surface ( figure 1 ) and deionized water to test the adsorption rate, see Table 4., and compare it with the PP melt-blown fiber material. From the comparison of the data in Tables 1 and 4, it can be seen that the adsorption ratio of PS...

Abstract

The invention discloses a PS(poly styrene) / PP (propene polymer) fiber material adsorbing underwater benzene serial substances at a high rate. The material has stronger adsorption selectivity to underwater benzene serial substances (toluene, dimethylbenzene and the like), namely, the adsorption rate to the underwater benzene serial substances is remarkably improved, and the adsorption ability to the benzene serial substances on the water surface is also improved while the water adsorption is reduced to a certain extent. The PS / PP fiber adsorption material adsorbing underwater benzene serial substances at a high rate disclosed by the invention is prepared from the following raw materials in part by weight: 100 parts of PP, 1-15 parts of PS and 0.01-1 part of auxiliaries.

Description

technical field [0001] The invention relates to a chemical fiber adsorption material and a preparation method thereof, more specifically a PS / PP fiber material for absorbing underwater benzene series with a high rate and a preparation method thereof, belonging to the technical field of environmental functional materials. Background technique [0002] The PP fiber adsorption material prepared by the general meltblown method is hydrophobic and lipophilic, has a large specific surface area, high porosity, fast oil absorption speed, and large magnification. It is widely used in the rapid treatment of crude oil spill environmental accidents to absorb the leaked crude oil Reduce the pollution of crude oil to the environment. At the same time, both the adsorbent material and the adsorbed crude oil can be recycled through separation. played an important role. In fact, the pollution of the ecological environment by the crude oil that exists in the form of dispersion, emulsification ...
