摘要:
An integrally molded automotive waterproof connector is disclosed which comprises a thermoplastic resin and integrated therewith an oil-bleeding silicone rubber, the thermoplastic resin containing a thermoplastic resin oligomer containing at least one aliphatic unsaturated group. In the connector, the adhesion between the thermoplastic resin and the silicone rubber is satisfactory regardless of the length of storage period as compared with connectors comprising a thermoplastic resin and a silicone rubber integrated therewith after priming. Further, the connector of the present invention is excellent in production efficiency and workability, is reduced in connector housing fitting force, and can retain satisfactory waterproofness.

摘要:
A thermoplastic resin composition comprising 100 parts by weight of a thermoplastic resin and 2 to 12 parts by weight of a thermoplastic resin oligomer containing 0.1 to 35% by weight of an aliphatic unsaturated group is molded with silicone rubber to form an integrally molded part. The thermoplastic resin composition maintains the inherent properties of the thermoplastic resin and firmly bonds with silicone rubber.

摘要:
In a polypropylene resin/silicone rubber integrally molded article, a polypropylene resin having an aliphatic unsaturated bond is integrally joined to an addition type silicone rubber at high bond strength. It is prepared by injection molding a modified polypropylene resin into a preform, injection molding a silicone rubber composition over the preform, and curing the composition at a temperature below the softening point of the polypropylene resin. Stronger bond is established when the silicone rubber contains a tackifier in the form of a compound containing in a molecule at least one hydrogen atom directly attached to a silicon atom and an alkoxysilyl, glycidyl or acid anhydride group or a --(CH.sub.2).sub.n -- linkage.
摘要:
An integrated thermoplastic resin/silicone rubber article is prepared by modifying a thermoplastic resin with a silicon-containing compound in monomer or polymer form, molding the thermoplastic resin into a shape, contacting an uncured silicone rubber with the molded thermoplastic resin, and curing the silicone rubber at a temperature below the softening point of the thermoplastic resin. The article in which the thermoplastic resin is firmly united with the silicone rubber is useful in electric, electronic and automotive applications while taking advantage of the inherent reliability in heat resistance, weather resistance and electrical properties of the silicone rubber.
