Brominated polyphenylene oxide and its use as flame retardant

Abstract: A brominated polyphenylene oxide having a molecular skeleton obtained by condensing tribromophenols and satisfying the requirements: (A) its 20 wt.% solution in chloroform has an absorbance at 600 nm of not larger than 0.6; (B) when 50 ml of ion-exchanged water is added to its 1.00 g/30 ml solution in dioxane, the resulting solution has an electroconductivity of not larger than 10 µS/cm measured at 25°C; and (C) when a mixture comprised of 20 % by weight of the brominated polyphenylene oxide and 80 % by weight of triphenyl phosphate is heated at 280°C for 20 minutes, the halide ion increase therein is not larger than 10 µmols per gram of the brominated polyphenylene oxide, is used as a flame retardant. When it is added to resin, the resin moldings are excellent in its flame retardancy, electric properties, physical properties, thermal stability and appearance (color hue), and they do not corrode molds.

Modified antibacterial polyformaldehyde plastics

Abstract: The invention relates to modified antibacterial polyformaldehyde plastics which comprise the following ingredients: 170 parts of polyformaldehyde, 10 parts of calcium carbonate, 6 parts of calcium stearate, 6 parts of ethylene glycol treatment agent, 7 parts of flexibilizer, 20 parts of titanium dioxide, 2 parts of glass fiber, 5 parts of phenolic resin and 4 parts of triphenyl phosphate. The prepared plastics have good mechanical property, good tensile strength and good impact resistance, and particularly the notch impact resistance is good. The prepared plastics have better mechanical property and forming processing performance.

Flame retardant silicone composition

Abstract: PROBLEM TO BE SOLVED: To obtain a stable flame retardant silicone composition capable of providing a silicone excellent in flame retardance without using a platinum compound as a flame retardant by blending a polyorganosiloxane as a base polymer with a microencapsulated organic phosphoric ester. SOLUTION: This flame retardant silicone composition is obtained by blending a silicone composition containing a polyorganosiloxane as a base polymer with an organic phosphoric ester (e.g. a triaryl phosphate such as triphenyl phosphate) which is a core substance so as to provide preferably 0.5-10 pts.wt. phosphoric ester based on 100 pts.wt. polyorganosiloxane. A polyurethane, etc., are preferred as a coating material for a microcapsule. When magnesium hydroxide having <=1.5μm average particle diameter is further blended, the flame retardance is preferably further improved. A cross-linking means according to a cross- linking mechanisnl is blended in the objective composition; however, an organic peroxide, e.g. dicumyl peroxide is cited as the cross-linking means.

Flame-retardant cured product and curable composition therefor

Abstract: PURPOSE:To prepare a flame-retardant cured product having excellent wear resistance and high surface hardness by reacting a monomer or oligomer contg. a diallyl compd. with a flame retardant in the presence of a polymn. initiator. CONSTITUTION:A flame-retardant cured product is obtd. by reacting a monomer or oligomer component contg. a diallyl compd. or a mixture of these components with a compsn. contg. a flame retardant in the presence of a polymn. initiator. Examples of the diallyl compd. are monomers and oligomers of a bisallyl carbonate of an aliph., alicyclic, or arom. dihydric alcohol, and the mixtures of these compds. The usable flame retardants include brominated flame retardants (e.g. tetrabromobisphenol), inorg. flame retardants (e.g. antimony trichloride), organophosphorus flame retardants (e.g. triphenyl phosphate), and inorg. phosphorus flame retardants (e.g. red phosphorus).

Preparation method of triphenyl phosphate

Abstract: The invention provides a preparation method of triphenyl phosphate. Firstly, phenol is added to an organic solvent, phosphorus oxychloride is added in a dropwise mode, meanwhile, a metal catalyst is added, and after a heat preservation reaction, triphenyl phosphate is obtained through after-treatment. The preparation method is simple in process step, high in product yield and low in production energy consumption, three-waste emission is greatly reduced, production cost is reduced, the product purity is high, the impurity content is low, and the yield is high.
