Roll-to-roll slot die coating method to create interleaving multi-layered films with chemical slurry coatings

An improved method for manufacturing a continuous self-healing barrier film is provided. The method includes slot-die coating opposing sides of a separator substrate with a curing agent slurry and a curable resin slurry using a single-sided coating line or a tandem coating line. The method also includes sequentially interleaving inner and outer protective layers via a continuous roll-to-roll process to create a multi-layered barrier film. The barrier film can optionally be formed into a barrier envelope, and an insulating core material can be inserted into the barrier envelope to define an enclosure. Evacuating and sealing the enclosure along a perimeter of the barrier envelop forms a self-healing vacuum insulation panel with excellent properties for use as a building material and in refrigeration systems, for example. The barrier film can alternatively be used in the manufacture of tires, roofing, cargo containers, food packaging, and pharmaceutical packaging, for example.

METHOD FOR REPAIRING SELF-SEALING TIRES

This invention discloses a technique for replenishing the level of sealant in self-sealing tires at the time that a puncture in the tire is being repaired or when the tire is being recapped. This technique provides the tire with its original level of self-sealing capabilities and will enhance the possibility of the tire remaining in service until it can be conveniently repaired. This method involves (1) injecting a liquid sealant formulation into the sealant layer of a self-sealing tire through at least one puncture hole therein, and (2) sealing the hole or holes in the supporting carcass and the innerliner of the tire. The sealant utilized is typically liquid polyisobutylene having a weight average molecular weight of 25,000 to 200,000. The sealant formulation used can optionally also contain a colorant or a pigment.
