The self-adhesive principle of VOLSUN silicone rubber self-adhesive tape
Self-adhesive is the phenomenon that the same kind of unvulcanized rubber materials are pasted and parked for a certain period of time to produce mutual adhesion and integration. It is the result of the mutual diffusion and penetration of rubber macromolecules on the two bonding surfaces through molecular thermal motion, so self-adhesiveness is an unidentified The unique characteristics of vulcanized rubber are also the basic characteristics of silicone rubber self fusing tape.
For silicone rubber self fusing tapes, self-adhesiveness is very important in the molding process. It has advantages and disadvantages for rubber processing. It provides adhesive force for the lamination and molding of various products to ensure that the lamination parts are firm, but some processes There is no need for self-adhesion in the link. In order to prevent adhesion, a release agent is also used. When packaging into rolls, a layer of transparent release film needs to be attached to prevent mutual adhesion.
When making silicone rubber self-adhesive tapes, when the unvulcanized rubbers are in contact with each other, the interface will permeate and diffuse. This molecular-scale mutual diffusion will make the two layers of glue blend together after a certain period of time. Ideally, its adhesive force can reach the strength of the rubber compound itself, so as to ensure the uniformity of the overall performance of the vulcanized product.
When the two layers of the silicone rubber self-adhesive tape are bonded together, the rubber macromolecular chains at the interface will form holes due to thermal movement during the mutual entanglement process, and then the adjacent molecular chains will be allowed to squeeze in on a segment scale. In the gap, with the extension of time, it finally merged into one.
