Problems solved by technology

If only the adhesive material is antistatic, the static electricity generated by the rubber surface of the protective film and the release material will still have a great impact on the product itself, failing to meet the needs of the market
Therefore, most of the antistatic protective films currently on the market have a high single surface resistivity after antistatic treatment, and the antistatic effect is unstable, failing to achieve a full range of antistatic effects.
In addition, antistatic may migrate to the surface of the object to be protected and cause pollution

Abstract

The invention relates to an omnibearing antistatic high-molecular protection film. The omnibearing antistatic high-molecular protection film comprises a high-molecular film matrix and an antistatic coating which is used for coating the surface of the high-molecular film matrix, an antistatic adhesive which is used for coating the surface of the high-molecular film matrix, and an antistatic releaselayer applied with the antistatic adhesive. The antistatic coating comprises the following components in parts by weight: 100-150 parts of polythiophene, 150-200 parts of isopropanol, and 50-100 parts of a dispersant. According to the invention, the surfaces of a back glue material of the protection film and a release material are subjected to special high-molecular treatment, an adhesive and a special high-molecular stock solution are subjected to modulation to obtain the high-molecular adhesive, antistatic effect of the material is greatly improved, and the omnibearing high-molecular protection film with long antistatic continuous time and stable effect can be obtained, a shelf life can achieve more than one year, a resistance value of the back glue material, the coating layer and the release material can achieve 10<6-10> omega, and the anti-static electricity cannot be transferred to the surface of a to-be-protected object to cause pollution.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an omnidirectional antistatic polymer protective film. Background technique [0002] In the development and production process of electronic products, with the continuous improvement of the demand for miniaturization, portability, multi-function, digitalization, high reliability and high performance of the whole unit, the miniaturization, integration and module of components The demand for globalization is becoming more and more urgent. Due to the increasing concentration of current integrated circuit components and parts, the withstand voltage is reduced, and the circuit area is reduced, which weakens the device's ability to withstand voltage shocks, and puts forward higher requirements for the electrostatic protection technology of electronic products. Electrostatic protection technology is getting more and more attention, and cannot be avoided or ignored. The main reasons are...
