Embodiment 1

[0024] After fully mixing the acrylic pressure-sensitive adhesive with a weight percentage of 63% and a dissolving agent with a weight percentage of 35%, add an antistatic auxiliary agent with a weight percentage of 0.9% and fully stir and mix, and finally add a solidification agent with a weight percentage of 1.1%. Stir evenly to obtain the antistatic protective film glue provided by the present invention for use.

[0025] Wherein, the acrylic pressure-sensitive adhesive is composed of polymethyl methacrylate and polyethyl methacrylate, the dissolving agent is ethyl acetate, and the antistatic auxiliary agent is potassium thiocyanate.

Embodiment 2

[0027] The specific usage method is the same as that of Example 1, wherein the weight percentage of the acrylic pressure sensitive adhesive is 81%, the percentage of the dissolving agent is 16%, the percentage of the antistatic auxiliary agent is 1.2%, and the weight percentage of the curing agent is 1.8%.

[0028] The acrylic pressure-sensitive adhesive is composed of polymethyl methacrylate, polyethyl methacrylate and polybutyl methacrylate, the dissolving agent is composed of ethyl acetate and toluene, and the antistatic auxiliary agent is thiocyanate potassium chloride.

Embodiment 3

[0030] Fully stirring and mixing 96.5% by weight of acrylic pressure-sensitive adhesive and 1.5% by weight of antistatic auxiliary, finally adding 2% by weight of a curing agent and stirring evenly to obtain the antistatic protective film provided by the present invention Ready to use with glue. In this embodiment, no dissolving agent is used, that is, the weight percentage of the dissolving agent is 0%.

[0031] Wherein, the acrylic pressure-sensitive adhesive is composed of polymethyl methacrylate and polybutyl methacrylate, and the antistatic auxiliary agent is lithium thiocyanide.

[0032] The following table is the performance comparison of the common antistatic acrylic protective film on the market and the acrylic protective film prepared by using the antistatic protective film glue provided by the present invention, it can be seen that the present invention has a significant antistatic effect.

Abstract

The present invention discloses an anti-static protection film glue, which comprises, by weight, 50-98.6% of an acrylic acid pressure sensitive adhesive, 0.5-1.5% of an anti-static auxiliary agent, 0.9-1.9% of a curing agent, and 0-46.6% of a dissolving agent. The anti-static protection film glue of the present invention has characteristics of good adhesion, good anti-static effect, and anti-static protection film production cost reducing.

Description

technical field [0001] The invention relates to the field of glue for protective films, in particular to a glue for anti-static protective films. Background technique [0002] In the process of handling or production and use of electrical and electronic products, the surface of the electronic and electrical products is extremely susceptible to contact pollution or scratches. It is necessary to cover the surface with a protective film to prevent it from being contaminated or damaged. In addition, the protective film used in electronic or electrical products must also have a characteristic, that is, no static electricity can be generated when it is removed, so as to avoid damage to the electronic and electrical products. In addition to the above requirements, the protective film used for screen protection also requires the protective film to be optical grade, the surface is very clean, and the naked eye looks like one with the screen. [0003] At present, there are two common...
