Problems solved by technology

Different industries have different requirements for the resistance value and light transmittance of anti-static coatings; The oil tank requires a resistance value of 108Ω~1011Ω. The above two fields do not require the light transmittance of the coating; Static indicators, durability, transparency and alcohol resistance all have high requirements, and ordinary antistatic coatings cannot meet the requirements
[0003]At present, the anti-static coatings used for plastic products on the market are mainly polythiophene short-term anti-static coatings, and their service life is short, 3 months to 1 year
Moreover, the antistatic performance of the current polythiophene antistatic coating will be significantly reduced after large-scale blistering, which cannot meet the application requirements of some high-end products.

preparation example Construction

[0050] In still other embodiments, the present invention also provides a method of preparing an anti-static coating, which comprises the steps of:

[0051] Step S1: Supply materials in accordance with the components of the anti-static coating according to the present invention;

[0052] Step S2: Mix the single wall carbon nanotubes with a portion of water to coarse milling to obtain a single-walled carbon nanotube dispersion;

[0053] Step S3: Mix the single-walled carbon nanotube dispersion and dispersing agent, then perform crushing, resulting in a crushing material;

[0054] Step S4: Mix the crushing material with alcohol and another part of water, then carry out the grinding, the grinding process is added to the material to the material, filtered, filtered, and filtered, extract the filtrate to obtain the present invention. Anti-static coating.

[0055] The above preparation method is simple, low cost, suitable for scale production.

[0056] Specifically, in some embodiments, ...

Abstract

The invention provides an antistatic coating, a preparation method thereof, and a blister product. The antistatic coating is prepared from, by weight, 0.02 to 0.4 part of single-walled carbon nanotubes; 0.06 to 1.5 parts of a dispersing agent; 1 to 10 parts of water-based hyperbranched polyester resin; 0.2 to 0.6 part of a fluorine wetting leveling agent; 75 to 95 parts of water; and 5-25 parts of alcohol. Compared with the traditional anti-static coating for the blister product, the anti-static coating disclosed by the invention has good anti-static effect, alcohol wiping resistance, adhesive force, transparency and ultraviolet aging resistance on the surface of the blister product. And a coating layer formed by the anti-static coating shows excellent resistance stability in the plastic uptake stretching process, and meets the requirement of large-size plastic uptake.

Description

Technical field [0001] The present invention relates to the field of coating materials, and more particularly to an anti-static coating, a preparation method thereof, and a blister article. Background technique [0002] Anti-static coating is a functional coating, accompanied by the continuous improvement of the development of the microelectronics industry, and has achieved increasing application and development. Different industries have different resistance values ​​and light transmittance requirements of anti-static coatings; such as floor coating requirements resistance value of 10 4 Ω ~ 10 9 Ω, steel oil tank requires resistance value of 10 8 Ω ~ 10 11 Ω, the above two fields have no requirements for the light transmittance of the coating; the field of anti-static indicators, durability, transparency and mexicity, and the ordinary anti-static coating cannot be satisfied. Require. [0003] At present, the anti-static coating for the plastic products in the market is mainly a ...
