Preparation method of organic titanium precursor polymer TPP-I (Triphenyl Phosphate) and application thereof in electrostatic conductive coating

Abstract: The invention provides a preparation method of an organic titanium precursor polymer TPP-I (Triphenyl Phosphate) and the application thereof in electrostatic conductive coatings and belongs to the technical field of preparation and application of new materials. The preparation method of the organic titanium precursor polymer TPP-I includes the steps of placing a mixture of titanium hydride powder,epoxy resin, nanodispersant, titanate coupling agents, silane coupling agents and solvent in a ball mill reaction tank for ball milling reaction under ultrasonic conditions, allowing titanium powderto initiate the chemical bond of the polymer and the lattice bond cleavage on the surface of titanium nanoparticles during a nanocrystallization process, producing ions or groups of extremely high surface activity, degrading polymers into small molecular oligomers that can conduct graft polymerization at high temperatures and pressures, realizing molecular structure reforming and obtaining the organic titanium precursor polymer TPP-I. The organic titanium precursor polymer TPP-I can be used for preparing primers and topcoat for the electrostatic conductive coatings.

Multiresidue Determination of Phosphoric Acid Triesters in Fish, Sea Sediment and Sea Water

Abstract: An analytical method was developed for determining residue of phosphoric acid triesters (tri-n-butyl phosphate, tris (2-chloroethyl) phosphate, tri-n-amyl phosphate, tris (2, 3-dichloropropyl) phosphate, triphenyl phosphate, tris (2-butoxyethyl) phosphate, tricresyl phosphate, tris (2, 3-dibromopropyl) phosphate, tris (4-tert-butylphenyl) phosphate in fish, sea sediment and sea water. Phosphoric acid triesters were extracted from these materials with acetonitrile and methylene chloride. After n-hexane-acetonitrile partition, the extract was cleaned up by activated charcoal column chromatography, followed by extraction with conc. sulfuric acid, washing with 0.5N sodium hydroxide solution, and finally Florisil minicolumn chromatography. The purified extracts were analyzed with a gas chromatograph equipped with a flame photometric detector (P-filter) and with a gas chromatograph-mass spectrometer. The separation on gas chromatography was found to be good with 10% OV-1 on Chromosorb W experiments (AW-DMCS) and 5% FFAP on Gas Chrom Q. Throughout the present method, the recoveries of phosphoric acid triesters were in the range of 60-95%, and the detection limits (fish) were approximately 1-5μg/kg.

Flame-retarding heat-resistant impact-resistant resin composition of excellent processability

Abstract: PURPOSE:To obtain the resin composition by mixing a thermoplastic resin with a specified polyphenylene ether and a phosphorus-containing flame retardant CONSTITUTION:This resin composition comprises 100 ptswt resin component comprising a thermoplastic resin (eg polystyrene thermoplastic resin or a rubber-modified styrene resin) and a polyphenylene ether (eg poly(2,6- dimethyl-1,4-phenylene ether) having a weight-average molecular weight of 30000-50000 and a weight-average molecular weight to number-average molecular weight ratio of 20-30, 1-40 ptswt phosphorus-containing flame retardant such as an organo-phosphorus compound (eg triphenyl phosphate) or red phosphorus, and optionally 0-30 ptswt triazine compound, 0-10 ptswt fluororesin and 0-10 ptswt higher fatty acid amide compound

Conductive resin composition

Abstract: PURPOSE:To prepare the title compsn. excellent in the flame retardance by compounding a polyphenylene ether resin, a polystyrene resin, a phosphric ester compd., and a specific carbon fiber, each in a specified amt. CONSTITUTION:100 pts.wt. compsn. comprising 20-97 pts.wt. polyphenylene ether resin (e.g. a polyphenylene ether), 0-70 pts.wt. polystyrene resin (e.g. a polystyrene), and 3-30 pts.wt. phosphoric ester compd. (e.g. triphenyl phosphate) is compounded with 4-45 pts.wt. carbon fiber having a density of 1.9g/cm or higher.

Rust preventive oil

Abstract: PURPOSE:To produce a rust preventive oil for removing solid lubricating surface treating on the surface of a steel sheet by incorporating a specific ratio of phthalic ester based or phosphoric ester based plasticizer to a base oil. CONSTITUTION:The rust preventive oil is prepared by adding 5-30 pts.wt. mixture of tricresyl phosphate, triphenyl phosphate, tributyl phosphate, diethyl phthalate or tricresyl phosphate with triphenyl phosphate or mixture of tricresyl phosphate with dibutyl phthalate into 100 pts.wt. base oil. When the rust preventive oil is applied on the solid lubricating surface treated steel sheet, the plasticizer in the rust preventive oil dissolves and removes the lubricating surface treating from the steel sheet and at the time of being coated with an adhesive, the steel sheet exhibits excellent adhesive power to a base material and is stuck strongly to the base material.
