摘要:
The invention relates to a flame-proofed polymeric composition suitable for coating workpieces, containing a vinyl acetate-containing thermoplastic polymer and an unsaturated elastomer containing double bonds as polymeric components, wherein the polymeric components are present in the form of a homogeneous polymeric mixture, and a mixture matrix vulcanized exclusively by a sulphur or sulphur-containing crosslinking system is formed, wherein the sulphur crosslinking system extends across the entire matrix and permeates the matrix completely, and—at least one flame retardant or a combination of flame retardants. The invention further relates to articles produced therefrom, and to composite elements coated with this composition and to a method for producing the same.
摘要:
Insulation materials have a coating of a partially cured polymer on a plurality of fibers, and the plurality of coated fibers in a cross-linked polymeric matrix. Insulation may be formed by applying a preceramic polymer to a plurality of fibers, heating the preceramic polymer to form a partially cured polymer over at least portions of the plurality of fibers, disposing the plurality of fibers in a polymeric material, and curing the polymeric material. A rocket motor may be formed by disposing a plurality of coated fibers in an insulation precursor, curing the insulation precursor to form an insulation material without sintering the partially cured polymer, and providing an energetic material over the polymeric material. An article includes an insulation material over at least one surface.

The present invention concerns an aqueous flame retardant composition for mineral fiber-based mats, in particular glass or rock fibers, which comprises: at least one thermoplastic or thermoset resin; magnesium hydroxide, Mg(OH)2, and aluminum hydroxide, AlOOH, as flame retarding agents; and optionally, carbon black. It also concerns mats treated with said flame retardant composition.

The present invention relates to a covering fabric for covering aircraft. The fabric itself may be coated with one or more layers of a crosslinked anionic aliphatic polyester-polyurethane dispersion and/or is woven from coated fibers or filaments. A covering fabric of the invention may be glued using a thermoactivatable heat-crosslinking adhesive. An advantage of the covering fabric of the invention is that there is no need for further coating of the fabric after covering, and thus significantly less weight is applied by the covering process. Furthermore, the user is able to apply the covering to an aircraft without using any organic solvents in adhesives, tension-inducing varnishes, thinners, fillers or colored varnishes. Thus, an environmentally friendly process is provided for the covering of aircraft.

The present invention provides a method for manufacturing a composite yarn of paper, e.g., traditional Korean paper, and a composite yarn manufactured thereby, a method for manufacturing a fabric using the same and an automotive interior material manufactured thereby. More particularly, the present invention relates to a method for manufacturing a composite yarn of traditional Korean paper by using a traditional Korean paper yarn and a synthetic yarn, in which the composite yarn can be used in weaving and knitting, and a method for manufacturing a fabric as an automotive interior material using the same. Accordingly, the present invention provides a method for manufacturing a composite yarn of paper, comprising twisting a tape-type paper yarn, and covering the twisted paper yarn as a ground yarn at least two strands of synthetic yarn as an effect yarn to manufacture a composite yarn of paper of 160˜700 denier.

摘要:
The present disclosure provides a method of forming a flame retarded composite article using a halogen-free thermosetting composition comprising a benzoxazine compound, a monobenzoxazine monomer, and a naphthalene epoxy. The flame retarded composite article formed is especially suited for use in aerospace, automobile, rail and marine applications.
摘要:
An insulating tape material, a method for production and usage thereof, for producing electrical insulation paper such as mica paper, which is contained in thermally conductive insulating tapes that are used for high-voltage insulation, for example. The insulating tape material has fiber reinforcement by means of a fabric, wherein the meshes of the fabric are filled by a particle composite which is preferably thermally conductive.
