Description

TECHNICAL FIELD

[0001] The application relates to the technical field of PVC materials, in particular to an environment-friendly antistatic PVC material and a preparation method and application thereof. BACKGROUND

[0002] Polyvinyl chloride (PVC) is a thermoplastic plastic with the second largest production after polyethylene, and is formed by polymerization of vinyl chloride monomers. The application fields of PVC are very wide, such as electrical insulation materials in industrial and agricultural industries, frames of buildings, indoor decoration, rainproof films for agriculture, and Teslin products.

[0003] The PVC molecular chain contains chloride ions, and the chloride ions have strong electronegativity, so the PVC molecular chains have strong mutual attraction. In addition, due to the steric hindrance effect, the vinyl chloride has good rigidity, hardness and excellent mechanical properties. At the same time, the existence of the polar group leads to a high resistivity, and static electricity is easily accumulated during processing and use, which causes static hazards and affects normal use. Especially in special places such as micro-device manufacturing workshops, laboratories and operating rooms, the static hazards caused by the devices made of PVC will cause serious losses. Therefore, it is urgent to reduce the static influence of PVC and make the use of PVC products safer. SUMMARY

[0004] In order to reduce the static influence of PVC, the application provides an environment-friendly antistatic PVC material and a preparation method and application thereof.

[0005] In the first aspect, the application provides an environment-friendly antistatic PVC material, which adopts the following technical scheme:

[0006] The environment-friendly antistatic PVC material comprises the following raw materials in parts by weight: 100 parts of PVC resin, 3-6 parts of stabilizer, 40-60 parts of plasticizer, 0.5-2 parts of antioxidant, 10-30 parts of sodium lignosulfonate modified by caprolactone, 0.5-2 parts of lubricant and 15-25 parts of conductive filler.

[0007] By adopting the above technical scheme, the lignosulfonate sodium molecule contains sulfonic acid groups and has water absorption performance. When added to the PVC material, the lignosulfonate sodium can absorb water molecules on the surface of the material and has a moisture absorption and antistatic effect. The lignosulfonate sodium modified by caprolactone has better compatibility with PVC, can be uniformly dispersed in the PVC system, and forms a uniform antistatic network. The conductive filler is dispersed in the PVC resin and cooperates with the lignosulfonate sodium modified by caprolactone to form a three-dimensional antistatic network from the inside to the surface of the PVC material, thereby giving the PVC material excellent antistatic performance. In addition, lignin is a natural polymer with aromatic rings, and is abundant in production and widely sourced, so it is an environment-friendly material.

[0008] Preferably, the sodium caprolactone-modified lignin sulfonate is prepared by reacting caprolactone and sodium lignin sulfonate at a mass ratio of 1:(2-10).

[0009] Preferably, the sodium caprolactone-modified lignin sulfonate is 10-15 parts by weight.

[0010] Preferably, the conductive filler is 20-25 parts by weight.

[0011] Preferably, the conductive filler is one or more of carbon black, graphene, and carbon nanotubes.

[0012] Preferably, the conductive filler is carbon black and / or graphene.

[0013] By adopting the above technical solution, carbon black and graphene synergistically improve the antistatic performance of the PVC material.

[0014] Preferably, the conductive filler is modified graphene, which is prepared by compounding titanate coupling agent and graphene at a mass ratio of 1:(10-18).

[0015] By adopting the above technical solution, graphene modified by the titanate coupling agent has better dispersibility in the PVC material. This helps to form a more uniform antistatic network, further improving the antistatic performance of the PVC material.

[0016] Preferably, the stabilizer is a calcium-zinc composite stabilizer.

[0017] In a second aspect, the present application provides a preparation method of the environment-friendly antistatic PVC material, which adopts the following technical solution:

[0018] A preparation method of an environment-friendly antistatic PVC material, comprising the following steps:

[0019] Mixing the components in the raw materials uniformly, extruding and granulating to obtain the environment-friendly antistatic PVC material.

[0020] In a third aspect, the present application provides an application of the environment-friendly antistatic PVC material, which adopts the following technical solution: An application of the environment-friendly antistatic PVC material, which can be used for the preparation of TESLIN products.

[0113] Detection method

The specific test results are shown in Table 2.

[0115] Table 2. Performance test of environment-friendly antistatic PVC material

[0116] Item Surface Resistance / Ω Item Surface Resistance / Ω Example 1 8.5 x 10 7 ]]> Example 8 5.2 x 10 7 ]]> Example 2 7.4 x 10 7 ]] Example 9 5.6 x 10 7 ]] Example 3 7.1 x 10 7 ]] Example 10 4.9 x 10 7 ]] Example 4 9.1 x 10 7 ]] Comparative Example 1 9.3 x 10 8 ]] Example 5 7.8 x 10 7 ]] Comparative Example 2 7.6 x 10 9 <!-- 6 -->]]> Example 6 8.3 x 10 7 ]]> Comparative Example 3 2.4 x 10 9 ]]> Example 7 6.2 x 10 7 ]]>

[0118] It can be seen from the combination of Example 1 and Comparative Example 1 and Table 2 that the surface resistance of the environment-friendly antistatic PVC material prepared in Example 1 is much lower than that of Comparative Example 1, which may be because: the sodium lignosulfonate modified by caprolactone is selected in Example 1, and the sodium lignosulfonate modified by caprolactone has better compatibility with PVC, can be uniformly dispersed in the PVC system, and form a more uniform antistatic network; while the sodium lignosulfonate in Comparative Example 1 is not modified.

[0119] It can be seen from the combination of Example 1 and Comparative Examples 2-3 and Table 2 that the surface resistance of the environment-friendly antistatic PVC material prepared in Example 1 is much lower than that of Comparative Examples 2-3, which may be because: Comparative Example 2 does not contain sodium lignosulfonate modified by caprolactone, but only contains conductive fillers; Comparative Example 3 does not contain conductive fillers, but only contains sodium lignosulfonate modified by caprolactone; while Example 1 contains both, the conductive fillers are dispersed in the PVC resin, and cooperate with the sodium lignosulfonate modified by caprolactone to form a three-dimensional antistatic network from the inside to the surface of the PVC material, thereby giving the PVC material excellent antistatic performance, and both are indispensable in function and cooperate with each other.
