Description

Low-temperature-resistant antistatic thermoplastic elastomer material and preparation method thereof

Technical Field

The invention relates to the field of high polymer materials, in particular to a low-temperature-resistant antistatic thermoplastic elastomer material and a preparation method thereof.

Background

Besides the high elasticity of rubber, the thermoplastic elastomer (Thermoplastic Elastomer, TPE for short) also has the workability of thermoplastic plastics, and in addition, the TPE has the advantages of wide adjustable range of hardness, good toughness, environmental protection and no toxicity, and very wide application field, and is mainly applied to the fields of daily consumer goods, kitchen supplies, automobiles, wires and cables, waterproof coiled materials, plastic floors/runways, electronic appliances and the like. TPE generally has a volume resistivity of 1012-1014 Ω·cm and good electrical insulation, but is prone to static electricity during use due to friction, and causes a series of disasters due to static discharge and electromagnetic interference. Static electricity accumulated on the surface of the product may cause difficulty in molding operation and affect the quality of the product. In the electronic and electrical industry, electrostatic discharge may cause breakdown of precision instruments and electronic components and may be scrapped. For the above reasons, research on the antistatic problem of TPE has been carried out domestically. The Chinese patent No. 106751080A discloses an antistatic thermoplastic elastomer alloy material, but the main resin is general plastic GPPS, the thermoplastic elastomer SEBS is only used as a toughening agent, the hardness of the obtained alloy material is higher, and the polyether type high-molecular antistatic agent is used, so that the alloy material is high in price, and the compatibility of polyether and the thermoplastic elastomer belonging to olefins is poor.

Therefore, a low-temperature-resistant antistatic thermoplastic elastomer material is developed, and the material has excellent low-temperature resistance and antistatic effect, and has wide market prospect and great economic value.

Disclosure of Invention

Based on the above, the invention aims to provide a low-temperature-resistant antistatic thermoplastic elastomer material which has excellent low-temperature resistance and excellent antistatic effect.

In order to achieve the above purpose, the invention adopts the following technical scheme:

the thermoplastic elastomer consists of a hydrogenated (styrene-butadiene-styrene) block copolymer, polypropylene and white oil.

In some embodiments, the low temperature resistant antistatic thermoplastic elastomer material is prepared from the following raw materials in parts by weight:

in some of these embodiments, the thermoplastic elastomer is comprised of the following components in parts by weight: 37-48 parts of hydrogenated (styrene-butadiene-styrene) block copolymer, 7-18 parts of polypropylene and 43-53 parts of white oil. Experiments show that the thermoplastic elastomer with the composition in parts by weight has better technical effect.

In some of these embodiments, the thermoplastic elastomer is comprised of the following components in parts by weight: 40 parts of hydrogenated (styrene-butadiene-styrene) block copolymer, 15 parts of polypropylene and 45 parts of white oil.

In some of these embodiments, the SEBS-g-MAH and E-MAH copolymers have a mass ratio of 3:1.

in some of these embodiments, the mass ratio of the total amount of SEBS-g-MAH and E-MAH copolymer to the carbon nanotubes is 5:2.

In some of these embodiments, the SEBS-g-MAH has a maleic anhydride grafting of 1wt% to 2wt%.

In some of these embodiments, the E-MAH copolymer (ethylene-maleic anhydride copolymer) has a maleic anhydride content of 78wt%.

In some of these embodiments, a 10wt% toluene solution of the hydrogenated (styrene-butadiene-styrene) block copolymer has a viscosity ∈1000mpa.s at 25 ℃.

In some of these embodiments, the polypropylene is a random polypropylene having a melt index of 11 to 20g/10min at 230 ℃/2.16kg test conditions.

In some of these embodiments, the white oil is a paraffinic white oil having a kinematic viscosity at 40 ℃ of 25-90cSt.

In some of these embodiments, the carbon nanotubes are multiwall carbon nanotubes. The multi-wall carbon nano tube has smaller specific surface energy than the single-wall carbon nano tube, relatively smaller aggregation and easier dispersion because the pipe diameter of the multi-wall carbon nano tube is usually larger than that of the single-wall carbon nano tube, so that the carbon nano tube is preferably the multi-wall carbon nano tube, and the antistatic performance of the obtained low-temperature-resistant antistatic thermoplastic elastomer material can be better improved.

In some of these embodiments, the antioxidant is selected from at least one of pentaerythritol distearyl diphosphate, tris- (nonylphenyl) phosphite, and phenyl tris (2, 4-di-t-butyl) phosphite; the lubricant is selected from erucamide and/or oleamide.

The invention also provides a preparation method of the low-temperature-resistant antistatic thermoplastic elastomer material.

The specific technical scheme is as follows:

a preparation method of a low-temperature-resistant antistatic thermoplastic elastomer material comprises the following steps:

(1) Uniformly mixing the SEBS-g-MAH, E-MAH copolymer and the carbon nano tube, adding the mixture into a double-screw extruder, extruding, cooling and granulating to obtain master batch;

(2) And (3) uniformly mixing the master batch, the thermoplastic elastomer, the antioxidant and the lubricant, adding the mixture into a double-screw extruder, and obtaining the low-temperature-resistant antistatic thermoplastic elastomer material through melting, extrusion, cooling and granulation.

The low-temperature-resistant antistatic thermoplastic elastomer material is prepared from raw materials comprising components TPE (comprising SEBS, PP and white mineral oil), SEBS-g-MAH, an E-MAH copolymer and carbon nanotubes, the prepared thermoplastic elastomer material has lower hardness and low temperature resistance by adopting the SEBS, PP and the white mineral oil in a specific proportion, and the carbon nanotubes can be well dispersed in the TPE component by adding the maleic anhydride graft SEBS-g-MAH and the maleic anhydride copolymer E-MAH in a matching manner. Maleic anhydride is easy to react with active groups such as hydroxyl, carboxyl and the like on the surface of the carbon nano tube, so that the compatibility of the carbon nano tube with SEBS-g-MAH and E-MAH is improved; because the SEBS-g-MAH and the SEBS base material have excellent compatibility, and the E-MAH and the PP have excellent compatibility, the carbon nanotubes are well dispersed in the TPE and the TPE, and the agglomeration of the carbon nanotubes is prevented, so that the prepared low-temperature-resistant antistatic thermoplastic elastomer material has excellent low-temperature resistance and excellent antistatic performance.

As can be seen from the performance test results of the above examples and comparative examples, the carbon nanotubes can be well dispersed in the TPE matrix resin by adding the SEBS-g-MAH and the ethylene-maleic anhydride copolymer E-MAH with specific grafting rates, so that the prepared thermoplastic elastomer material has excellent antistatic performance while having low temperature resistance.

In comparison with example 3 and example 6, the carbon nanotubes are poorly dispersed in the matrix resin without the addition of SEBS-g-MAH and E-MAH copolymers, and may agglomerate and fail to form continuous conductive paths, thereby resulting in a thermoplastic elastomer material having a higher surface resistivity. Comparative examples 2 and 3 were compared with example 6, in which only a single SEBS-g-MAH or E-MAH copolymer was added, the dispersibility of the carbon nanotubes in the matrix resin was inferior to that of example 6, and the surface resistivity of the material was higher than that of example 6. Therefore, the cooperation of the SEBS-g-MAH and the E-MAH copolymer can play a synergistic role, and the dispersibility of the carbon nano tube in the matrix resin can be more effectively improved compared with the single SEBS-g-MAH or E-MAH copolymer, so that the antistatic performance of the obtained thermoplastic elastomer material is more effectively improved.

Comparative example 4 compared with example 6, the substitution of PP-g-MAH for the E-MAH copolymer of example 6 resulted in poor dispersion of the carbon nanotubes in the matrix resin compared with example 6, and higher surface resistivity of the material compared with example 6. Comparative example 5 compared with example 6, replacing SEBS-g-MAH in example 6 with POE-g-MAH, the dispersion of carbon nanotubes in the matrix resin was inferior to that of example 6, and the surface resistivity of the material was higher than that of example 6. Therefore, the compatibility of the SEBS-g-MAH and the E-MAH copolymer can more effectively improve the dispersibility of the carbon nano tube in the matrix resin compared with other compatilizers, thereby more effectively improving the antistatic performance of the obtained thermoplastic elastomer material.

Comparative example 6 compared with example 6, the proportions of SEBS, PP and white oil are different, so that the hardness of the composite material is higher, the low temperature resistance of the composite material is affected, cracks appear on the surface when a low temperature brittleness test at-60 ℃ is carried out, and the low temperature performance of the composite material is poor under the condition of the proportion.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
