Assignee:

PPG Industries, Inc. - Pittsburgh PA

International Classification:

B32B 900

US Classification:

428392

Abstract:

Glass fibers reinforced polymeric polymers can be produced with high strength properties such as tensile strength, flexural strength and impact strength by using sized glass fiber strands of the present invention. The sized glass fiber strands have a residue of an aqueous sizing composition comprising: aqueous dispersible, emulsifiable, or solubilizable polyurethane polymer, polyepoxide polymer, polyethylene-containing polymer, and wax, where the weight ratio of the polyethylene containing polymer to the wax is in the range of about 25 to 1 to about 1 to 25, and one or more amino silane coupling agents. In addition to the amino silane coupling agent, the sizing composition may have an epoxy silane coupling agent and/or a lubricant modified silane coupling agent. The wax can be deleted from the composition, when the polyethylene-containing polymer has limited branching. The sized glass fiber strands can be produced by conventional forming process or by a wet chopped glass fiber forming process.

Inventors:

Chester S. Temple - McKees Rocks PA

Assignee:

PPG Industries, Inc. - Pittsburgh PA

International Classification:

C08L 2312

US Classification:

260 296WB

Abstract:

A binder composition and method for using same in sizing compositions for treating glass fibers is provided. The binder composition is an aqueous emulsion containing isotactic carboxylated polypropylene along with amorphous carboxylated polypropylene, base, and surfactant. The isotactic carboxylated polypropylene is incorporated in the emulsion by a method of co-emulsification of the isotactic and amorphous carboxylated polypropylene in a ratio of 1:1 to 1:4 parts by weight along with the base and surfactant. Water is added to the co-emulsified blend to obtain the emulsion with the desired solids content.

Inventors:

Chester S. Temple - McKees Rocks PA

Assignee:

PPG Industries, Inc. - Pittsburgh PA

International Classification:

D02G 300

US Classification:

428378

Abstract:

Glass fibers are prepared with a chemical treatment resulting in chemically treated glass fibers having utility in reinforcing thermoplastic polymers such as polyolefins. The chemically treated glass fibers have a dried residue of an aqueous chemical treating composition having one or more amino organo coupling agents, an aqueous emulsion of an acid or anhydride modified polyolefin having one or more surfactants, wherein the polyolefin is neutralized with an organic or inorganic base with a basicity less than the basicity of the amino moiety of the coupling agent, a binder stabilizer, one or more film forming polymers, and water. The aqueous chemical treating composition is essentially free of cationic lubricants that are amidated fatty acids and polyvinyl acetate homopolymer. The chemically treated glass fibers can be prepared in a wet chop or dry chop process, wherein the chopped glass fiber strands eventually have a moisture content of less than 20 weight percent prior to volatilization of the formed moisture. The chemically treated glass fibers are used to reinforce thermoplastic polymers such as polyolefins and particularly polypropylene in any molding operation to produce glass fiber reinforced thermoplastic articles.

Inventors:

Edward C. Hsu - Pittsburgh PA
Chester S. Temple - McKees Rocks PA

Assignee:

PPG Industries, Inc. - Pittsburgh PA

International Classification:

B32B 2700
D02G 300

US Classification:

428392

Abstract:

Treated glass fibers are provided that are more dispersible in aqueous media. The glass fibers are treated with a composition having a nonionic surfactant and a cationic quaternary ammonium salt surfactant. The composition may be added simultaneously or sequentially with the chopped glass fibers to the aqueous media in which the glass fibers are to be dispersed. Also, glass fibers can be treated with an aqueous treating composition having the composition and produced into wet or dry chopped glass fibers having a length of about 1/16 of an inch to about 3 inches. The treated glass fibers have good dispersibility in aqueous media with or without the addition of dispersing agents.

International Classification:

C08F 434

US Classification:

523203

Abstract:

An aqueous sizing composition has an aqueous emulsion containing an organic peroxide solid at 20. degree. C. having improved stability and dilutability. The aqueous emulsion has the solid organic peroxide, which, for example, can be a bisperoxide or peroxy ester, solubilized in an effective amount of an organic peroxide that is a liquid at 20. degree. C. for example, a bisperoxide or peroxyester. The emulsion has one or more cationic, anionic or nonionic lubricants in effective amounts to disperse the peroxides in water. The emulsion also has sufficient amounts of water to make an oil-in-water emulsion. In addition to the emulsion, the sizing composition has an organo silane coupling agent and lubricant and possibly a film forming polymer.
