Problems solved by technology

[0006] Therefore, the technology of adding an antistatic substance to the release layer of the release film was originally tried, but in this case, the release characteristics such as the release force and residual adhesive ratio required for the release film deteriorated, and The anti-static performance is not very good, so it is not suitable for products applied to the IT field

Embodiment 1

[0051] A silicone release layer is formed on one side of the polyethylene terephthalate (PET) film, and an antistatic layer is formed on the other side, such as figure 1 As shown, a release film test piece with a three-layer structure was produced. The weight proportion of above-mentioned organosilicon release layer accounts for 10 parts according to the weight of organopolysiloxane, the weight of hydrogen-containing organopolysiloxane accounts for 0.01 part, the weight of platinum chelate accounts for 0.1 part, and solvent (toluene ) constitutes 100 parts by weight.

[0052] And, the weight proportion of the antistatic mixture of above-mentioned antistatic layer is, as the weight of the acryloyl chloride resin of adhesive agent 15 parts, the weight of polyethylenedioxythiophene (PEDOT) as antistatic agent 10 parts, ethanol (common 30 parts by weight of alcohol) and 45 parts by weight of water, the antistatic mixture is coated on a polyethylene terephthalate (PET) film to for...

Embodiment 2

[0054] Same as above-mentioned embodiment 1, antistatic layer is placed between polyethylene terephthalate (PET) film and organic silicon release layer, has figure 2 3-layer construction shown. Specifically, the same antistatic mixture as in Example 1 was coated on a polyethylene terephthalate (PET) film to form an antistatic layer, and then a silicone release layer was formed on the antistatic layer.

Embodiment 3

[0056] Compared with above-mentioned embodiment 1, antistatic layer is formed on both sides of polyethylene terephthalate (PET) film, as image 3 As shown, it has a 4-layer structure. Specifically, an antistatic compound is coated on both sides of a polyethylene terephthalate (PET) film to form a two-layer antistatic layer, and then a silicone release layer is formed on one side. At this time, the same antistatic mixture as in the above-mentioned examples was used for the two antistatic layers.

Abstract

The invention relates to a release film with a base film and a release film. The release film of an anti-static layer including binder and anti-static agent and the manufacturing method thereof are provided. The release film possesses excellent release force and, remaining binder ratio and other release characteristics, the anti-static performance is excellent, and the release can be effectively applied in products in IT field.

Description

technical field [0001] The present invention relates to a release film with excellent antistatic performance and a manufacturing method thereof, more specifically, a release film with good release characteristics and excellent antistatic performance and a manufacturing method thereof. Background technique [0002] Generally speaking, the main purpose of the release film is to protect the adhesive layer (or adhesive layer). Release films are generally used in industrial adhesive tapes (or adhesive tapes), etc. In recent years, applications in IT fields such as mobile phones, LCDs, semiconductors, and displays have increased rapidly. [0003] The release film includes a base film and a release layer. The base film is mostly made of paper or plastic film, and the release layer is mainly composed of silicon mixture. The release film is required to have release characteristics such as release force and residual adhesive rate. Specifically, while the adhesive (adhesive) layer i...
