摘要： Methods for making fire retardant material including fire retardant cellulosic insulation are described. The methods include arrangements for partitioning fibers derived from fiber feedstocks and adding at least a portion of fibers of one or more feedstocks and a fire retardancy chemical compound to a mixer prior to fiber drying. The fibers may be disentangled and/or partitioned prior to mixing with the fire retardancy chemical compound. The fibers may be partially dewatered prior to the drying or other steps of the methods. The feedstock may include old newsprint (ONP), old corrugated containers (OCC), and/or other cellulose-based materials. The method further includes retaining the fibers feedstock and the chemical compound together for enough time to ensure adherence and impregnation of enough of the chemical to and in the fibers after the drying process. Fibers may be partitioned and disentangled prior to, during, and/or after treatment with the fire retardancy compound. The fire retardant cellulose insulation may be a standalone product or may be a component of a finished insulation end product.

摘要： Disclosed are a paper-based electromagnetic shielding composite with flame retardant properties and its preparation method and application, belonging to the technical field of electromagnetic shielding. In the present disclosure, PI fibers are modified by polydopamine and grafted with carbon nanotubes, polyimide fiber paper is prepared by a wet papermaking technology, an in-situ synthesis method is used to enable conductive MOFs and polymer PPy to grow on the fiber paper, and finally polyimide resin is sprayed onto the paper to prepare the paper-based electromagnetic shielding composite with flame retardant properties. The method is simple in process without complex synthesis equipment, and solves the problems that polyimide fiber paper is poor in paper forming property and paper mechanical property, and carbon nanotubes are easy to agglomerate in paper and limited in addition amount in the prior art. The paper-based composite has good mechanical property, heat resistance, flame retardancy and electromagnetic shielding performance.

摘要： 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.

摘要： This disclosure provides high-efficiency and low-energy-consumption synthetic methods of a series of phosphorus-nitrogen-based intumescent flame retardants and the use thereof in paint flame retarding. 1 part by weight of a phosphorization agent and 0.5-4.0 parts by weight of a nitrogen-containing foaming agent are uniformly mixed and stirred at room temperature, and an amount of water is further added to emit heat and initiate reaction. 0.5-3.0 parts by weight of a charring agent and 0.5-4.0 parts by weight of a hydroxy-containing polyfuctional crosslinking agent are then added, and reacted with stirring. An amine compound is finally added for neutralization until pH value is 5-8, and solid liquid separation is performed. The solid portion is dried to obtain a main body portion of a phosphorus-nitrogen-based intumescent flame retardant. The resultant filtrate is diluted with ⅓-⅔ volume of water, and a flame retardant product is obtained. This flame retardant product is mainly used in the flame retarding of paper and cotton fabrics. The main body and different proportions of other nitrogen-containing foaming agents and charring agents are uniformly mixed and pulverized into nano- and micro-scale, and a phosphorus-nitrogen-based intumescent flame retardant is obtained. The nano- and micro-scale phosphorus-nitrogen intumescent flame retardant is mixed into a paint at a weight ratio of 15-30%, to obtain a flame-retardant paint which is capable of maintaining mechanical and physical properties of the paint. The phosphorus-nitrogen-based intumescent flame retardant of this disclosure is an intumescent flame retardant having a synergistic effect of phosphorus and nitrogen.
