Problems solved by technology

However, when the antistatic agent is coated on the surface of the cover tape, because the resin layer reduces the adhesive force between the hot melt adhesive of the cover tape and the carrier tape, it will cause vibration when the cover tape is peeled off, which will affect the stability of the carrier tape. easy to jump out

Abstract

The invention discloses a special antistatic coating material for a cover tape, wherein the coating material comprises the following raw material components by mass: 10-50% of poly(3,4-ethylenedioxythiophene) / poly(styrenesulfonate (PEDOT / PSS), 0.05-1.5% of a wetting agent, 2-15% of an aqueous resin, 1-15% of an active synergist, 0.05-3% of a slipping agent and 50-70% of water. According to the invention, styrene-butadiene latex or acrylonitrile-butadiene latex is selected as bonding resin in formula components, and is matched with a proper wetting agent, and after the surface of a cover tape is coated with an antistatic layer, the vibration generated during stripping of an upper cover tape can be well relieved, and the stability during stripping of a carrier tape is kept.

Description

technical field [0001] The invention relates to an antistatic paint, in particular to a special antistatic paint for a cover tape used for packaging electronic components. Background technique [0002] Cover tape is a tape-shaped product used in the field of electronic packaging, used in conjunction with carrier tape. The cover tape usually uses polyester or polypropylene film as the base layer, and is compounded or coated with different functional layers (antistatic layer, adhesive layer, etc.), which can be sealed on the surface of the carrier tape under external force or heating to form The closed space protects the electronic components in the carrier tape pocket. In order to prevent electronic components from being electrostatically attracted to the cover tape, the surface of the cover tape usually has antistatic requirements. Polymer antistatic agents are usually added to the cover tape coating. However, this type of ionic antistatic agent works by absorbing water, ...
