Problems solved by technology

[0003] At present, anti-static tape is mainly used for packaging electronic components, so as to seal the electronic components and isolate the external environment, so as to protect the electronic components. The traditional anti-static tape is composed of a base material and an adhesive layer. The material is made of plastic film and antistatic agent, and the adhesive tape composed of the base material and the adhesive layer has a single structure, does not have high temperature resistance and waterproof effect, and the antistatic effect is poor; in addition, the adhesive is mostly made of acrylate pressure. Sensitive adhesives, this type of adhesive has general heat resistance, at higher temperatures, poor heat resistance and aging resistance, easy to lose pressure sensitivity, even after cross-linking acrylate pressure-sensitive adhesive can only be used at 150 Short-term use at ℃

Embodiment 1

[0034] On the basis of the above structure, in this embodiment, the surface of the substrate 1 is coated with an antistatic layer 3, which is easy to prepare and can effectively improve the antistatic performance of the adhesive tape, thereby quickly releasing the static electricity released by the electronic components, effectively Protect electronic components.

Embodiment 2

[0036] On the basis of Embodiment 1, in this embodiment, the antistatic layer 3 is prepared from an antistatic agent, and the substrate 1 can obtain good antistatic performance by using the antistatic agent.

[0037] The above-mentioned antistatic layer 3 is usually directly coated with an antistatic agent on the substrate 1, and the antistatic agent adopts an existing antistatic agent. Mixed two types.

[0038] The externally-coated antistatic agent refers to a type of antistatic agent used for coating on the surface of polymer materials, that is, the antistatic layer 3 involved in this embodiment. Generally, it is formulated into a solution with a mass fraction of 0.5% to 2.0% with water or ethanol before use, and then it is attached to the surface of the polymer material by coating, spraying or dipping, and then dried at room temperature or hot air. Forms an antistatic coating. Most of these are cationic antistatic agents, and some are amphoteric and anionic antistatic ag...

Embodiment 3

[0041] On the basis of the above structure, in this embodiment, the adhesive layer 2 is silica gel. Silicone has the function of high temperature resistance, so the tape can avoid failure when used in a high temperature environment, and effectively maintain the high temperature resistance of the tape.

[0042] In addition, the thickness of the adhesive layer 2 is 0.02-0.04mm, which is suitable, which can not only satisfy various properties of the adhesive tape, but also save costs.

Abstract

The invention relates to an anti-static high-temperature-resistant adhesive tape. The anti-static high-temperature-resistant adhesive tape comprises a base material with an anti-static function, wherein an adhesive layer with an anti-static function is fixedly adhered to the lower surface of the base material. The anti-static high-temperature-resistant adhesive tape of the invention has the beneficial effects that a preparation method is simple and convenient, and the adhesive tape has the characteristics of static electricity resistance, high temperature resistance, good initial viscosity, high holding power, wide use temperature range, high resistance and the like, and has wide application prospects in the electronic industry.

Description

technical field [0001] The invention relates to the technical field of adhesive tapes, in particular to an antistatic and high temperature resistant adhesive tape. Background technique [0002] Anti-static high temperature resistant tape, that is, anti-static adhesive tape used in high temperature working environment. This type of tape is mainly made of Pi or Pet film as the base material, and one side is coated with silicone glue. The temperature resistance is usually between 120 degrees and 260 degrees. It has the characteristics of high viscosity, high temperature resistance, no shrinkage, and washable. It is often used for pasting protection of circuit boards, batteries, cameras and other products. [0003] At present, anti-static tape is mainly used for packaging electronic components, so as to seal the electronic components and isolate the external environment, so as to protect the electronic components. The traditional anti-static tape is composed of a base material...
