Abstract: The invention relates to a flame retardant containing bamboo powder and flame-retardant fiber for a mine. The flame retardant is characterized by containing the following components in parts by weight: 10 parts of halogen-free flame-retardant polyamide, 40-60 parts of aluminum hydroxide, 20-25 parts of aluminum hydroxide, 10 parts of microencapsulated red phosphorus, 10 parts of expandable graphite, 15 parts of ammonium polyphosphate (APP), 10 parts of zinc borate, 30 parts of flame-retardant fiber, 20 parts of bamboo powder, 5 parts of phosphine oxide, 5 parts of tricresyl phosphate, 5 parts of triphenyl phosphate, 5 parts of isopropyl phenyl diphenyl phosphate, 5 parts of tributyl phosphate, 5 parts of trioctyl phosphate, 5 parts of cresyl diphenyl phosphate, 5 parts of N-hydroxymethyl propanamide type methylphosphonate and 5 parts of reinforcing agent, wherein the reinforcing agent is one of glass fiber, carbon fiber, wood fiber, bentonite, carbon black, montmorillonite and oil shale ash.

Production of cellulose ester film for photographic material

Abstract: PURPOSE:To obtain the titled film which has excellent mechanical strength with good workability, by immersing a cellulose ester in a non-swellable solvent to lower its viscosity, dissolving the ester is an org. solvent and molding it into a film. CONSTITUTION:A cellulose ester such as cellulose triacetate or cellulose acetate butyrate is immersed in a non-swellable solvent such as benzene or toluene. The mixture is stirred for 24hr or longer. A plasticizer such as triphenyl phosphate or dimethoxy-ethyl phthalate is blended with said cellulose ester whose viscosity has been lowered by the above immersion treatment. The mixture is dissolved in an org. solvent such as methylene chloride or methanol. The resulting soln. is extruded into a film on a substrate and the solvent is evaporated. The solid film is peeled from the surface of the substrate to obtain the desired cellulose ester film for photographic materials.

Flameproof Rubber Modified Styrenic Resin Composition

Abstract: PURPOSE: A flame retardant rubber-reinforced polystyrene resin composition is provided, which is free from a halogen-based flame retardant, and is improved in the stability against fire, the environmental stability, the heat resistance, the impact strength and the fluidity. CONSTITUTION: The polystyrene resin composition comprises 70-94.5 wt% of a rubber-reinforced polystyrene resin; 0.5-10 wt% of a polyphenylene ether resin; and 5-20 wt% of a phosphoric acid ester compound comprising 40-80 parts by weight of an oligomer-type phosphoric acid ester compound having a hindered methyl group and 20-60 parts by weight of triphenyl phosphate. Preferably the rubber-reinforced polystyrene resin comprises 70-97 parts by weight of at least one monomer selected from the group consisting of an aromatic monoalkenyl monomer and an alkyl acrylate or methacrylate monomer and 3-30 parts by weight of a rubber selected from the group consisting of a butadiene-based rubber, an isoprene-based rubber, a copolymer of butadiene and styrene and an alkyl acrylate-based rubber, and has a particle size of 0.5-2.0 micrometers. Preferably the oligomer-type phosphoric acid ester compound is represented by the formula I, wherein n is a number average degree of polymerization and is 1-5; X is catechol, resorcinol, hydroquinone or bis phenylene diol of the formula II(wherein Y is an alkylene of C1-C5, an alkylidene of C1-C5, cyclo alkylidene of C5-C6, -S- or -SO2-, and z is 0 or 1).

Improvements in or relating to plastic compositions

Abstract: A film-forming composition comprises an organic film-forming material, a plasticizer therefor containing chlorine or bromine and, as a stabilizer, a small proportion of a salt of an aromatic carboxylic acid in which a carboxyl group is directly attached to an aromatic nucleus. The film-forming material may be a cellulose ester of a carboxylic acid, such as cellulose acetate, propionate, acetate propionate or acetate butyrate; a cellulose ether such as ethyl or benzyll cellulose; or a polyvinyl or polyvinylidene compound such as polyvinyl chloride or a copolymer of vinyl chloride with vinyl acetate or of vinyl chloride and/or vinylidene chloride with acrylonitrile and/or methacrylonitrile. The plasticizer may have hydrogen attached to a carbon atom adjacent to a carbon atom to which is attached chlorine or bromine. Specified plasticizers are tri(beta - chlorethyl) phosphate, beta - chlorethylmethoxyethyl - butoxy - ethyl phosphate and the chlorobutyl and chlorobutoxy-butyl esters referred to in Specification 651,662, e.g. delta-chlorobutyl acetate, delta-chlorobutoxy-butyl acetate, and di-(delta-chlorobutyl) phthalate. Other plasticizers such as tricresyl or triphenyl phosphate may also be present. The stabilizer may be an alkali metal salt of phthalic acid, preferably a di-alkali metal salt and particularly disodium phthalate, or the sodium or other alkali metal salt of benzoic acid, isophthalic acid, terephthalic acid, p-toluic acid, p - methoxy - benzoic acid, alpha - or betanaphthoic acid or salicylic acid. The use of corresponding salts of calcium, barium, strontium, magnesium or lead is mentioned. The compositions may contain colouring matters, the presence of the stabilizer being particularly beneficial when the colouring matter is one which, like 1-amino-4-hydroxy-anthraquinone, 1 : 4 - diamino - anthraquinone, 1-ethanol - aminoanthraquinone, Rhodamine 6G or the azo dye from diazotized p-nitroaniline and N - di - (beta - hydroxyethyl) - m - chloraniline, is deleteriously affected by the action of heat and/or light in the presence of the plasticizer. In the example 100 parts of cellulose acetate flake is mixed with 50 parts of acetone, 30 parts of trichlorethyl phosphate, 10 parts of triphenyl phosphate, 0.3 part of disodium phthalate or sodium benzoate and 0.1 part of 1-amino-4-hydroxy-anthraquinone, the mixture is worked on heated rolls until the acetone content is reduced to about 10 per cent, and the sheets from the rolls are stacked and pressed at about 100 DEG C. into a solid block. The block is then cut into sheets, seasoned to remove acetone and finally polished by pressing warm between polished metal sheets. The Provisional Specification also refers to compositions in which the stabilizer is an alkali metal salt of hexahydrobenzoic acid or of an acid which is wholly aliphatic or which contains an aromatic nucleus to which a carboxyl group is indirectly attached, as in phenylacetic acid.
