Problems solved by technology

[0002] In the prior art, in the field of electronic products, most of the various antistatic films are coated on the surface of the film with coatings containing metal ions (or carbon powder), and then dry-operated to form an antistatic film, which is conductive The performance is good, and the effect of removing static electricity is also good, but the surface fastness of the coating is low and cannot withstand friction. Part of the coating on the surface coating after friction will fall onto the protected object (such as IC parts, capacitors, etc.) etc.) These contaminated electronic components will be destroyed as a result. Therefore, to change such a situation, the usual method is to cover these films with a layer of adhesive tape to protect these coatings. This method is not only The process is complex and cumbersome, and it also reduces the static electricity removal performance, thereby limiting its application range. Because of this, organic coatings have also been developed to replace these metals (including carbon-containing), but these organic coatings cannot be combined with organosiloxanes. Compatible, therefore, can not cause antistatic release film

Embodiment 1

[0026] Embodiment one: refer to figure 1 , the release film described in this embodiment comprises a substrate 1 made of a polyethylene terephthalate film PET film and an antistatic coating I2 coated on the upper surface of the substrate 1, and the antistatic coating I2 consists of It is composed of ethyl silicate. In this embodiment, the antistatic coating I2 made of ethyl silicate on the upper surface has good conductivity and can take away the static electricity on the surface of the release film, thereby achieving the effect of driving away static electricity.

Embodiment 2

[0027] Embodiment two: refer to figure 2 , the structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is: on the basis of the structure of Embodiment 1, a layer of release layer I3 is added on the antistatic coating I2, and the release layer Layer I3 consists of organosiloxane. This embodiment not only has a good effect of removing static electricity, but also utilizes the hydroxyl OH in the polyethylene terephthalate film PET film and organosiloxane to absorb the moisture content H in the air 3 o + and OH － Combined, the surface impedance of the release film is reduced, so as to play a release function and prevent the substrate from being charged.

Embodiment 3

[0028] Embodiment three: refer to image 3 , the structure and principle of the present embodiment are basically the same as those of the second embodiment, the difference being: on the basis of the structure of the second embodiment, an antistatic coating II4 is added on the lower surface of the substrate 1 to prevent static electricity Coating II4 is composed of ethyl silicate system. In this embodiment, not only the upper surface can prevent the substrate from being charged and dispel static electricity, but the lower surface also has the effect of dispelling static electricity, the effect is better, and the application range is wider.

Abstract

The invention discloses an integrative antistatic release film with an antistatic function and a release function as well as a manufacture method of the film. The release film comprises a substrate and an antistatic coating I, wherein the substrate consists of a polyethylene glycol terephthalate (PET) film, and the antistatic coating I is coated on the substrate and consists of ethyl silicate systems. The PET film and oxhydryl (OH) in organic siloxane absorb moistures (the combination of H3O<+> and OH<->) in the air, and the surface resistance of the release film is reduced, so the release function is realized, the substrate electrification is prevented, in addition, the antistatic coating consisting of the ethyl silicate systems has good electric conductivity, the static on the surface of the release film can be brought away, and the static removal effect is reached and is very stable and good. Further, the integrative antistatic release film and the manufacture method have the advantages that the firmness of the surface of each layer is high, the friction resistance is realized, in addition, the manufacture process is simple, and the production cost is low.
