With high temperature can be solved rapidly solidified aluminum plating film transfer?

Aluminum plating film composite transfer main reason has two: one is a two-component adhesive in high temperature curing process, the main agent and curing agent rapid crosslinking of the internal stress generated from each other. Say so, because have experiments show: if the compound good aluminum plating film not into aging chamber, curing at room temperature ( Take several days to fully cured, no significance to practical production, only the experiment) Hours, or at room temperature curing aging chamber after cure, aluminized transfer phenomenon will greatly reduce or eliminate. And, with 50% solid content of the adhesive, that is, low solid content of composite aluminum plating film, adhesive to transfer phenomena will be better, because of low solid content of the adhesive in the process of crosslinking, form a reticular structure without high solid content adhesive to form dense mesh structure, the internal stress less uniform, not uniform intensive effect on aluminized layer. Again, general plating aluminum special adhesive to remove the main agent is slightly different with ordinary adhesive agent, curing agent is usually less than ordinary adhesive, there is also to reduce or relieve adhesive crosslinking curing process of the role of internal stress, in order to reduce the transfer of aluminized layer. So I don't agree with the way to adopt high temperature fast curing transfer method to solve the aluminized layer, feeling the results backfire. Now a lot of flexible packaging manufacturers in compound aluminum plating film all use water-based adhesive, from the perspective of the structure characteristics of aqueous adhesive, should also prove the above statement. Another phenomenon is that the of aluminized transfer on the three layer compound, usually/PET/VMPET/PE this structure. Generally we are composite PET/VMPET/first. After this layer composite aluminized layer is generally not transfer. Only after the compound layer 3 PE, aluminized layer transfer occurred. Through the experiment we found that when peel three layer composite good spline, the spline if under certain tension ( The spline tension is artificially) , aluminized layer won't move, and once get rid of tension, aluminized layer will transfer immediately. This suggests that the PE film contraction deformation, also produced a similar to the adhesive curing produced in the process of the role of internal stress. So the composite such three layers structure of products, should try to reduce the tensile deformation of PE film. So, at the time of aluminized transfer, must consider the deformation problem of PE, followed by adhesives. At the same time, this structure is the most afraid of water, even with a little water to infiltrate aluminized composite membrane layer, produces serious delaminating.
