High odor eliminating property is provided to a building material for interiors by compounding a hydrazide compound. Additionally, the odor eliminating property of the building material for interiors is improved and hygroscopicity and size stability at the time of use are provided by adding and compounding an organic carbide, an inorganic hygroscopic material, and a water repellent. Also, an interior structure in which these building materials for interiors are employed is provided.

This invention relates to a sheetlike wholly aromatic polyamide shaped article useful as electrical insulating materials excellent in corona resistance (corona durability) and in surface smoothness. The corona durability of said sheetlike shaped article is increased to 150 minutes or above by adding a nonionic polymer flocculant to an aqueous dispersion comprising 10 to 90% by weight of mica particles, preferably treated with a silane coupling agent and 90 to 10% by weight of a wholly aromatic polyamide stock (fibrids and fibers) in obtaining the sheetlike shaped article from the aqueous dispersion by wet shaping.
摘要:
One or more layers of a sheet comprising (1) 60% to 99%, based on the weight of solids, of vermiculite delaminated by mechanical means only, (2) 1% to 40%, based on the weight of solids, of at least one fibrous material and (3) 0.1% to 4%, based on the weight of the vermiculite, of at least one flocculating agent, can be used to protect heat-sensitive substrates such as resin matrix composites from fire or heat.
摘要:
A fibrous composite material in the form of individual fibres, sheets, layers or lightweight blocks comprising non-combustible fibres and lamellae of a layer mineral, a method for the manufacture of the fibrous composite materials by applying lamellae of a layer mineral to the fibres preferably from suspension followed by removal of the liquid phase of the suspension, and use of the fibrous composite materials for the fire-protection of substrates.
摘要:
Disclosed are flocced mineral materials which may be utilized to prepare high temperature resistant, water resistant articles. These materials are prepared by utilizing, as a starting material, a gellable layered swelled silicate that has an average charge per structural unit that ranges from about -0.4 to -1 and which contains interstitial cations which promote swelling with a source of at least one species of multiamine derived cations.
摘要:
A high temperature filter material, comprising a non-woven glass fiber matrix including mica particles, polymer micro-bits and a uniformly distributed binder system, is made by a wet laid procedure, as used in paper-making. A composition comprising the mica particles and polymer micro-bits, used in making the filter material, and a method of preparing the composition are also disclosed.

This invention is directed to the preparation of neutralized polyelectrolyte complexes exhibiting hydrophobic behavior containing crystals of an organic polycation exchanged lithium and/or sodium water-swelling mica. The process for making such products comprises:(1) forming a glass-ceramic body containing crystals selected from the group of fluorhectorite, hydroxyl hectorite, boron fluorphlogopite, hydroxyl boron phlogopite, and solid solutions among those and between those and other structurally-compatible species selected from the group of talc, fluortalc, polylithionite, fluorpolylithionite, phlogopite, and fluorphlogopite;(2) contacting that body with a polar liquid to cause swelling and disintegration of the body accompanied with the formation of a gel; and(3) contacting said gel with a source of organic polycations to cause a reaction between the Li.sup.+ and/or Na.sup.+ ions from the interlayer of the crystals and to neutralize the charge density of the crystals, thereby forming neutralized polyelectrolyte complex, said organic polycations being selected from the group of(a) a primary amine solubilized with acid,(b) a secondary amine solubilized with acid,(c) a tertiary amine solubilized with acid,(d) a quaternary ammonium acid salt,(e) a quaternary phosphonium acid salt, and(f) a ternary sulfonium acid salt.
