Embodiment 1

[0061] The preparation of embodiment 1 antistatic release film

[0062] 1. Preparation of slurry

[0063]

[0064] Mix the above raw materials in order and stir for 30mim to form a uniformly mixed slurry.

[0065] 2. Preparation of antistatic release film

[0066] 1) Wrap the PET base film on the unwinding device 2, and the PET base film passes through the coating device 3 through the transmission wheel;

[0067] 2) Put the prepared slurry between the rollers 8 and 9, transfer the paint to the roller 10 by extrusion, the rollers 10 and 11 squeeze each other, transfer the roller 11, and apply the paint on the surface of the PET base film 1 , coating thickness 0.5μm;

[0068] 3) The coated PET base film enters the oven 4 through the transmission wheel for thermal curing, the curing temperature is 80 degrees, and the curing time is 10 seconds, then enters the UV curing box 5, turns on the air knife, and nitrogen rushes into the UV curing box 5 for light curing. UV intensity ...

Embodiment 2

[0070] The preparation of embodiment 2 antistatic release film

[0071] 1. Preparation of slurry

[0072]

[0073]

[0074] The preparation method is the same as in Example 1.

[0075] 2. Preparation of antistatic release film

[0076] 1) Wrap the PE base film on the unwinding device 2, and pass the PE base film through the coating device 3 through the transmission wheel;

[0077] 2) Put the configured slurry between the rollers 8 and 9, transfer the paint to the roller 10 by extrusion, the rollers 10, 11 squeeze each other, transfer the roller 11, and coat the slurry on the PE base film 1 Surface, coating thickness 2μm;

[0078] 3) The coated PE base film enters the oven 4 through the transmission wheel for thermal curing, the curing temperature is 120 degrees, and the curing time is 30 seconds, then enters the UV curing box 5, turns on the air knife, and nitrogen rushes into the UV curing box 5 for light curing. UV intensity is 120W, dose is 100J / cm 2 , Irradiatio...

Embodiment 3

[0080] The performance detection of embodiment 3 antistatic release film

[0081] 1. Anti-static test

[0082] Testing equipment: surface resistance tester

[0083] Temperature: 22℃±5℃

[0084] Humidity: 30%-80%

[0085] Method: Stick the tester on the surface of the film to be tested and read the data.

[0086] To test the antistatic ability of the antistatic release film of Example 1, the above test method was used to measure a set of data every 24 hours, and each set of data was measured 5 times, and the average value was taken. The control group used commercially available anti-static release film (purchased from Xinhao Adhesive Products Factory)

[0087] figure 2 The test data shows that the antistatic force is very stable and will not fluctuate significantly with time. It is better than the anti-static release film currently on the market. The resistance value of the anti-static release film on the market will increase with time, and the anti-static ability will d...

Abstract

The invention relates to an anti-static release liner, comprising a base membrane and a functional layer, wherein the functional layer is prepared from the following components in parts by weight: 0.5-1 part of conducting polymer resin, 1-2 parts of hydrogen-containing silicon oil, 5-10 parts of vinyl organic silicon resin, 0.05-0.2 part of platinum complex catalyst and 0.05-0.2 part of photoinitiator. The anti-static release liner disclosed by the invention has stable characteristics, double curing, namely heat curing and photo curing, is adopted, curing is thorough, chemical and physical properties are stable, stripping resistance and anti-static capacity are stable, an adhesive force is good, and less silicon is transferred. The invention has the advantages of a simple process, high production efficiency, low cost and less waste in production.

Description

technical field [0001] The invention relates to an antistatic release film, in particular to an antistatic release film with dual curing of light and heat and a preparation method thereof. Background technique [0002] In the use of release materials, due to the mutual friction, peeling, extrusion, etc. between the material and the machine guide roller and the material and the material, the surface area of ​​the material will store charges of different natures. When this charge accumulates to a certain extent, it will A discharge phenomenon occurs. The discharge of static electricity will have a great impact and damage on production, such as material adsorption of dust, material coating breakdown, human body electric shock, fire, etc. [0003] Among the release materials currently used in the market, most of them are products with an insulating surface. Customers often experience electrostatic discharge during use, which will lead to a large number of defective products and...
