Definitions

  • the invention relates to a method for increasing the adhesion between the first surface of a first sheet material and a first surface of a second sheet material.
  • the simple physical pretreatment techniques under atmospheric pressure are now used advantageously for the surface treatment of the joining part in order to achieve a higher anchoring force with a self-adhesive tape.
  • pretreatments of the surfaces may be performed. These pretreatments enable or strengthen the intermolecular forces of the joining partners.
  • pretreatments including chemical pretreatment by primer application or physical pretreatment by means of plasma or corona treatment.
  • G. Habenicht, 2009, Springer Verlag, Berlin / Heidelberg gives an introduction to surface treatment: The strength of adhesive bonds or the bond between surface and pressure-sensitive adhesive tape can be strengthened by chemical bridges.
  • organosilicon compounds silanes
  • the chemical primer is applied to the surface prior to application of the pressure-sensitive adhesive tape Since the intermolecular forces between the silane molecules are weak, the bifunctional adhesion promoter reacts below with the adherend surface (polycondensation reaction) and the adhesive molecules of the pressure-sensitive adhesive tape (polyaddition or polymerization reaction tion).
  • the reaction mechanism is shown schematically in the attached figure.
  • Plasma is called the 4th state of matter. It is a partial or fully ionized gas. By supplying energy, positive and negative ions, electrons, other excited states, radicals, electromagnetic radiation and chemical reaction products are generated. Many of these species can cause changes in the surface to be treated. In sum, this treatment leads to an activation of the adherend surface, specifically a higher reactivity.
  • This treatment can be carried out both on the surface of the adherend, as well as on the adhesive. Also, a combination of both treatments is possible. Likewise, this treatment is used to increase the adhesion between the first surface of a first sheet material (eg an adhesive) and a first surface of a second sheet material (eg a backing material).
  • the widespread corona treatment also called corona discharge or dielectric barrier discharge, represents a filamentary plasma and takes place mainly as a high-voltage discharge with direct contact to the surface to be treated by the discharge gas of the ambient air is converted into a reactive form. Due to the impact of the incident electrons, molecular cleavages occur at the adherend surface. The resulting free valences allow attachment of the reaction products of the corona discharge. These deposits allow for improved adherence properties of the adherend surface, but can also cause damage to the surface due to the immediate action of the discharge
  • the plasma treatment has a limited durability in terms of activation of the boundary layer, so that it is treated promptly or predominantly immediately before the lamination process.

  • the plasma is formed between the two laminating rollers which are grounded and a high-voltage electrode which simultaneously has an opening for the bonding agent.

  • the prior art is characterized in that the pretreatments predominantly relate to the carrier material or the joining part in order to build up a higher anchoring force to the adhesive or to the self-adhesive tape.
  • the treatment of adhesive and substrate is known. As a rule, the treatment is carried out with separate plasma discharge devices. With simultaneous treatment of the adhesive and the substrate, both are conducted directly through the discharge zone according to the known state of the art, which involves the risk of surface damage and thus reduced adhesion forces.
