Embodiment 1-11

[0050] Taking Example 1 as an example, Example 1 discloses an antistatic polymer film, which is characterized in that the raw materials include the following components by weight: 20 parts of polymer material, 5 parts of carbon nanotubes, and 2 parts of antistatic agent .

[0051] The antistatic agent comprises the following components by weight: 3.4 parts of 1,6-caprolactam, 2.8 parts of sodium alkylsulfonate, and 3.8 parts of 6-aminocaproic acid.

[0052] The polymer material is polystyrene.

[0053] The preparation method of antistatic polymer film, comprises the following steps:

[0054] 1,6-caprolactam, sodium alkylsulfonate, and 6-aminocaproic acid are melted and polycondensed to obtain a copolymer product, the heating temperature is 200-280°C, the reaction time is 3 hours, and the reaction process is carried out at 150 rpm Stir the melt at a high speed to finally obtain a copolymerized product; then dry the copolymerized product at a heating temperature of 60° C. and ...

Embodiment 12-19

[0062] The difference between Examples 12-19 and Example 5 is that the content of each component in the antistatic agent is different, the unit is gram, and the specific values ​​are shown in Table 2.

Embodiment 21

[0066] The difference between Example 21 and Example 5 is that the antistatic polymer film of Example 21, the raw materials also include the following components by weight: 1 part of methyl cellulose, 3 parts of sodium dioctyl succinate sulfonate .

[0067] The preparation method of antistatic polymer film, comprises the following steps:

[0068] 1,6-caprolactam, sodium alkylsulfonate, and 6-aminocaproic acid are melted and polycondensed to obtain a copolymer product, the heating temperature is 200-280°C, the reaction time is 3 hours, and the reaction process is carried out at 150 rpm Stir the melt at a certain speed; dry the copolymerized product at a heating temperature of 60°C and a constant temperature time of 3 hours.

[0069] Then dry the obtained solid matter and perform ball milling with a ball-to-material ratio of (27):1 and a rotating speed of 360 rpm to obtain an antistatic masterbatch with a particle size of 0.01-0.1nm;

[0070] Take the polymer material, heat an...

Abstract

The invention relates to the field of polymer films, and particularly discloses an antistatic polymer film and a preparation method thereof. The antistatic polymer film is prepared from, by weight, 20-40 parts of a polymer material, 4-15 parts of carbon nanotubes and 1-6 parts of an antistatic agent, wherein the antistatic agent is prepared from, by weight, 2-8 parts of 1,6-caprolactam, 1-6 partsof alkyl sodium sulfonate and 2-7 parts of 6-aminocaproic acid. According to the invention, the antistatic performance of the antistatic polymer film is improved, and the influence on the mechanical properties of the antistatic polymer film is reduced.

Description

technical field [0001] The application relates to the field of polymer films, more specifically, it relates to an antistatic polymer film and a preparation method thereof. Background technique [0002] Polymer materials refer to materials composed of polymer compounds. With the rapid improvement of my country's economic construction level, polymer materials have been widely promoted and applied. [0003] A characteristic characteristic of polymer materials is insulation, so polymer materials will generate static electricity during use. Static electricity is likely to cause hidden dangers in the use of polymer materials and affect the normal operation of the equipment. Moreover, static sparks are very likely to cause fires or explosions, causing great damage to people's lives and property. In order to avoid this potential safety hazard, scholars and experts have developed antistatic technology for polymer materials. The main method is to add antistatic agents or conductive p...
