US Patent:

43496016, Sep 14, 1982

Filed:

Dec 21, 1979

Appl. No.:

6/106032

Inventors:

Walter H. Brueggemann - Chagrin Falls OH
John A. Brenner - Independence OH

Assignee:

Ferro Corporation - Cleveland OH

International Classification:

B29C 508
B29D 900

US Classification:

428323

Abstract:

A molding process, resinous formulations for use in the process, and the resulting products are disclosed characterized in that the product comprises mainly a bulk or fill resinous body having a film or skin of a cross-linked polyester resin formed about the body. Even though the body has intricate curving surface contours, the film is smooth and free of surface tears and blemishes. The product is molded by first spraying formulated, dry particles of a partially cured polyester resin against a hot mold to cause the particles to fuse and flow and form a substantially continuous skin or film on the mold. Thereafter, the bulk resin is added and the mold is heated to cure the polyester resin as well as the bulk resin and to interreact the bulk and polyester resins together to mold the bulk resin with a film of the polyester resin.

US Classification:

Abstract:

A moldable sound control composite is disclosed combining in itself when molded damping, barrier performance, and structural strength for use within a predetermined environment temperature range. As such, the moldable composite is not applied to other structures to damp their sound generation, but forms by itself a complete structural member having not only desirable sound reducing properties but desirable strength properties as well. The composite comprises a blend of a primary non-viscoelastic organic polymeric resinous material intended to impart structural strength to the composite, a secondary viscoelastic organic polymeric resinous material to provide damping performance, and filler material adapted to densify the composite and impart barrier performance. Optionally, at least one of the primary and secondary resinous materials may be thermosetting. By virtue of the blend of all of these ingredients, the molded composite has a glass transitional temperature range generally corresponding to the predetermined environmental temperature range for which the composite is designed for use and a maximum loss factor, n, falling within that range.

As such, the moldable composite is not applied to other structures to damp their sound generation, but forms by itself a complete structural member having not only desirable sound reducing properties but desirable strength properties as well. The composite comprises a blend of a primary non-viscoelastic organic polymeric resinuous material intended to impart structural strength to the composite, a secondary viscoelastic organic polymeric resinuous material to provide damping performance, and filler material adapted to densify the composite and impart barrier performance. Optionally, at least one of the primary and secondary resinuous materials may be thermosetting. By virtue of the blend of all of these ingredients, the molded composite has a glass transitional temperature range generally corresponding to the predetermined environmental temprature range for which the composite is designed for use and a maximum loss factor, n, falling within that range.

A molding process, resinous formulations for use in the process, and the resulting products are disclosed characterized in that the product comprises mainly a bulk or fill resinous body having a film or skin of a cross-linked polyester resin formed about the body. Even though the body has intricate curving surface contours, the film is smooth and free of surface tears and blemishes. The product is molded by first spraying formulated, dry particles of a partially cured polyester resin against a hot female mold to cause the particles to fuse and flow and form a substantially continuous skin or film on the female mold. Thereafter, the bulk resin is added and the mold is heated to cure the polyester resin as well as the bulk resin and to interreact the bulk and polyester resins together to mold the bulk resin with a film of the polyester resin.
