Problems solved by technology

[0003] As people become increasingly strict with the quality of electronic products, in order to ensure the quality of electronic products, all links in the production process must be strictly controlled. Carrying glue and the like, it will undoubtedly affect the quality of electronic products, and even lead to scrapping in severe cases
However, the light-shielding tapes on the market have poor release, anti-static, and light-shielding effects, resulting in a low utilization rate of light-shielding tapes for electronic products.

Abstract

The invention discloses a light-shading adhesive tape. The light-shading adhesive tape includes a light-shading basal layer which is a black PET film. The adhesive tape also includes a black printingink layer, an antistatic layer, an acrylic acid pressure sensitive adhesive layer and a separating layer which are formed on the light-shading basal layer in order; wherein the black printing ink comprises acrylic resin, leadless carbon black, an adhesive force promoter, a levelling agent, an antifoaming agent and a dispersing agent; and the antistatic layer comprises a polyvinyl alcohol solvent,polyoxyethylene alkyl ether and a surfactant. The prepared light-shading adhesive tape has good separating, antistatic and light-shading effects.

Description

technical field [0001] The invention relates to the technical field of light-shielding tapes. Background technique [0002] With the development of electronic information technology, electronic products such as mobile phones, computers, and digital cameras are becoming more and more popular, and light-shielding tapes are usually used in the production of electronic products. However, the main function of the adhesive tape in the prior art is to prevent the chip from being polluted, corroded and moisture-proof. [0003] As people become increasingly strict with the quality of electronic products, in order to ensure the quality of electronic products, all links in the production process must be strictly controlled. Carrying glue and the like, it will undoubtedly affect the quality of electronic products, and even lead to scrapping in severe cases. However, the light-shielding tapes on the market have poor release, anti-static, and light-shielding effects, resulting in a low ...
