Abstract

The invention relates to the technical field of material surfaces, in particular to a preparation method of a double-layer antistatic silica gel protective film, the double-layer antistatic silica gel protective film comprises a release film, an organic silicon modified PET film layer and a PET film layer which are sequentially stacked, the outer side face of the release film is coated with an antistatic coating, an antistatic agent is added into the organic silicon modified PET film layer, and an antistatic sterilizing coating is coated on the outer side surface of the PET film layer; according to the preparation method of the double-layer PET antistatic silica gel protective film, the outer side face of the release film is coated with the antistatic coating, the antistatic agent is added into the organic silicon modified PET film layer, and the outer side face of the PET film layer is coated with the antistatic sterilizing coating, so that the antistatic performance of the antistatic silica gel protective film in the storage and use processes is remarkably improved; the use safety of the antistatic silica gel protective film is obviously improved.

Description

technical field [0001] The invention relates to the technical field of protective films, in particular to a preparation method of a double-layer PET antistatic silica gel protective film. Background technique [0002] PET (polyethylene terephthalate) is a semi-crystalline polymer with high melting temperature and glass transition temperature. Due to the insulating properties of PET itself, it is easy to generate and accumulate static charges during contact and friction. The existence of electrostatic charge makes the surface of PET products easy to absorb dust during storage and use, which affects the appearance effect; in the application of PET products such as electronics and electrical appliances, when the electrostatic charge capacity reaches a certain value, it will also cause abnormal discharge due to discharge. security incident. [0003] The double-layer PET antistatic silicone protective film uses PET (polyester film) as the base material, is coated with an adhesiv...
