10808175 · 2020-10-20 ·

The invention relates to the use of expanded graphite for reducing flammability and/or combustibility, in particular the use thereof as a flame protection agent and/or a fire protection agent, for materials and/or products which consist of or comprise wood fibers, cellulose fibers, wood powder, cellulose powder, wood granulates, cellulose granulates, and/or polyolefin-based materials. The invention further relates to materials and/or products which consist of or comprise wood fibers, cellulose fibers, wood powder, cellulose powder, wood granulates, cellulose granulates and/or polyolefin-based materials. In order to reduce the flammability and/or combustibility, expanded graphite is embedded into the materials and/or products, in particular in the form of a flame protection agent and/or a fire protection agent. The invention also relates to such an agent, in particular a flame protection agent and/or a fire protection agent, wherein expanded graphite is used alone or in combination with a boric acid/borax/alkali salt mixture. A particularly preferred area of use is binders, glues, and/or materials, products, and/or pre-products containing polyolefin-based materials in particular, preferably for damping (walls, floors, ceilings) and/or for floor and wall fittings. The invention is characterized by surprising advantages in fire protection tests with vertical edge flaming.

COMPOSITIONS FOR REDUCING INHALATION OF TOXIC AIR POLLUTION COMPONENTS

The present invention relates to a composition, textile, and mask for reducing the inhalation of pollutants. The composition includes an aqueous solution of an inorganic iodide compound, a metal phthalocyanine, and a polymeric binder. The inorganic iodide can be cuprous iodide, the metal phthalocyanine can be iron phthalocyanine, and the polymeric binder can be polyvinylpyrrolidone or polyvinyl alcohol. This pollutant-inactivating composition neutralizes pollutants such as nitrogen dioxide, sulfur dioxide, ozone, volatile organic compounds and other unpleasant airborne agents, without requiring elevated temperatures or bulky canisters containing adsorbents. Optionally, a humectant can also be incorporated into the coating solution to retain moisture in the active filter matrix, which enhances the activity of the composition to inactivate oxidizing gases and other toxic constituents of air pollution.

SELF-FUSED GRAPHENE FIBER AND METHOD OF PREPARING THE SAME
20200040519 · 2020-02-06 ·

Disclosed in the present disclosure are a self-fused graphene fiber and a method of preparing the same. Dried graphene oxide fibers are soaked in a solvent to swell and then the fibers are pulled out and coalesced. After being dried, the graphene oxide fibers are fused together, and then are further reduced to obtain a self-fused graphene fiber. The entire self-fusion process can be quickly finished within one minute without adding any additional binder. The operation is simple and time-saving. The process is environmentally friendly; the bond strength is high, and the excellent properties such as outstanding mechanical strength and electrical conductivity of the graphene fibers themselves can be maintained. The present disclosure has great research and application value for further preparation of two-dimensional graphene fabrics or three-dimensional network bulks with excellent performance.
