specific Embodiment approach 1

[0015] Specific Embodiment 1: In this embodiment, an antistatic protective film is composed of an antistatic layer, a main film layer and an antistatic adhesive layer; the main film layer is arranged on the antistatic layer and the antistatic layer. between adhesive layers;

[0016] The antistatic layer consists of 27 to 31 parts of antistatic polymer, 68 to 72 parts of alkyl urea derivatives, 9 to 11 parts of curing agent, 0.05 to 1.1 parts of antifoaming agent and 1 to 1 parts by mass. 20 parts of organosilicon compounds; the antistatic polymer is a quaternary ammonium base polymer; the alkylurea derivative is octadecyl ethylene urea; the curing agent is urea-formaldehyde resin; The defoaming agent is an alkylphenol polyoxyethylene ether; the organosilicon compound is a polyether siloxane copolymer;

[0017] The main film layer is a polyethylene terephthalate film;

[0018] The antistatic adhesive layer is made of 27 to 58% of the main agent, 27 to 58% of the dissolving ag...

specific Embodiment approach 2

[0023] Embodiment 2: This embodiment is different from Embodiment 1 in that: the thickness of the antistatic adhesive layer is 50-55 um. Other steps and parameters are the same as those in the first embodiment.

specific Embodiment approach 3

[0024] Embodiment 3: This embodiment is different from Embodiment 1 or Embodiment 2 in that: the thickness of the main film layer is 20-25 μm. Other steps and parameters are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to an anti-static protective film in order to solve the problems that when an existing polyester film is used, static electricity is easily generated, and an existing anti-static protective film is difficult to store and poor in strength and tensile resistance. The anti-static protective film is composed of an anti-static layer, a body film layer and an anti-static adhesive layer. The body film layer is arranged between the anti-static layer and the anti-static adhesive layer. The anti-static layer comprises an anti-static polymer, an alkyl urea derivative, a curing agent, a defoaming agent and an organic silicon compound. The body film layer is a polyethylene glycol terephthalate film. The anti-static adhesive layer is prepared from a main reagent, a dissolution agent, a curing agent and an anti-static agent. The surface resistivity value of the anti-static protective film is 107-1011 ohm, and the anti-static protective film has a two-side anti-static protection function, solves the problem that the strength and tensile resistance of the existing anti-static protective film are poor, and is easy to take care of.

Description

technical field [0001] The invention belongs to the technical field of protective films, and in particular relates to an antistatic protective film. Background technique [0002] Polyester film is used for packaging materials such as food packaging, information memory materials, building materials, electronic materials, printing materials, etc., as substrate films or engineering films. However, polyester films tend to generate static electricity due to friction during use and then absorb dust. It has seriously affected the quality of the product; in the prior art, the antistatic film obtained after carrying out antistatic compounding to the polyester film has antistatic effect, but the storage time of the existing antistatic protective film is shorter, and it is kept in a roll state in the memory When it is easy to produce adhesion and then cause waste, the strength and stretch resistance of the existing antistatic protective film are extremely poor, which affects the use of...
