Abstract: A process for producing a cement for adjusting a rubber product comprising 100 parts by weight of a rubber component and 10 to 500 parts by weight of an inorganic filler. In the first mixing step, the rubber component and components for compounding are mixed while the amount of the inorganic filler is kept in the range of 0 to 20 parts by weight per 100 parts by weight of the rubber component. In the second mixing step, (1) the remaining amount of the inorganic filler is mixed using a closed mixing machine, or (2) a master batch of the inorganic filler and the rubber component is mixed in a solution. Since an inorganic filler having a great specific gravity can be mixed in a great amount, a cement containing a solid component having a great specific gravity and providing a coating film exhibiting improved resistance to heat degradation can be produced efficiently.

Abstract: The present invention provides new polymer induction bonding technology. Induction heating technologies are utilized to weld, forge, bond or set polymer materials. The invention provides controlled-temperature induction heating of polymeric materials by mixing ferromagnetic particles in the polymer to be heated.

This invention is applicable to bonding thermoplastic materials, wherein only the area to be heated has ferromagnetic particles in it; bonding of thermoset composites, which have been processed with a layer of thermoplastic material on one side; curing of thermoset adhesives or composite resins; or consolidating thermoplastic composites.
