The high-efficiency antistatic polypropylene modified material is prepared by the process. The properties are shown in Table 1.
Table 1: performance data.
| Example 1 | Example 2 | Example 3 | Example 4 | Example 5 | Example 6 | Comparative example 1 | |
| Melt index (g/10 min) | 21.15 | 20.36 | 19.87 | 14.75 | 22.96 | 17.23 | 20.72 |
| Notched impact strength (kJ/m)2) | 23.42 | 25.85 | 27.29 | 42.25 | 4.51 | 9.65 | 27.38 |
| Flexural strength (Mpa) | 28.31 | 27.78 | 27.52 | 22.26 | 35.18 | 24.65 | 27.38 |
| Flexural modulus (Mpa) | 1802.26 | 1775.91 | 1762.35 | 794.85 | 2386.48 | 1193.14 | 1746.47 |
| Surface resistivity (omega) | 3.5×105 | 5.5×107 | 1.8×109 | 9.5×106 | 7.3×107 | 2.5×107 | 5×1016 |
The lower the surface resistivity value of the main material, the better the antistatic effect. As can be seen from table 1, the electrical resistivity of the material surface can be significantly reduced by compounding the antistatic agent in the polypropylene composite system, the electrical resistivity can be reduced by 3.5 × 105 Ω most obviously in example 1 and by 11 orders of magnitude, the electrical resistivity is gradually increased with the decrease of the addition amount of the antistatic agent in examples 1, 2 and 3, and the electrical resistivity is not greatly changed when the addition amount of the antistatic agent is the same in examples 2, 4, 5 and 6 for different formulations. In terms of mechanical properties, the flexural modulus of examples 1, 2 and 3 is changed compared with the comparative example, and the flexural modulus of example 5 is higher than the comparative example. The impact toughness of the examples 1, 2 and 3 is not changed much compared with the comparative example, and the impact toughness of the example 4 is greatly improved compared with the comparative example. In summary, in the case of the same formula of example 1, example 2, example 3 and comparative example, the mechanical properties are well maintained while the antistatic agent of the present invention is added to meet the antistatic requirement.
Table 2: performance data.
| Example 2 | Comparative example 2 | Comparative example 3 | |
| Melt index (g/10 min) | 20.36 | 20.64 | 22.75 |
| Notched impact strength (kJ/m)2) | 25.85 | 26.49 | 18.25 |
| Flexural strength (Mpa) | 27.78 | 27.52 | 28.26 |
| Flexural modulus (Mpa) | 1775.91 | 1789.35 | 1828.85 |
| Surface resistivity (omega) | 5.5×107 | 4.6×1011 | 7.5×108 |
As can be seen from table 2, when polyacrylamide is used alone as the antistatic agent, the antistatic effect is not as good as that of the compounded antistatic agent, and when sodium pyrrolidone carboxylate is used alone as the antistatic agent, the antistatic effect is equivalent to that of the compounded antistatic agent, but the impact toughness is lower than that of the compounded antistatic agent.
The high-efficiency antistatic polypropylene modified material can be modified by common additives, such as a plasticizer, a fluidity modifier, a heat stabilizer, a mold release agent, a colorant, other thermoplastic resins and the like.
Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
