Abstract:
Provided are a resin additive composition which is excellent in fluidity and can impart excellent physical properties to a thermoplastic resin, a thermoplastic resin 5 composition, and a molded article thereof. A resin additive composition is composed of a phosphoric acid ester compound (A) represented by the following general formula (1): R 'P-p (1) ~Na (in the formula (1), R to R4 each independently represent a hydrogen atom or a linear or 0 branched alkyl group having 1 to 9 carbon atoms, and R r epresents an alkylidene group having 1 to 4 carbon atoms) and a fatty acid sodium salt (B) represented by the following general formula (2): R -C-0-Na (2) (in the formula (2), R6 represents a group introduced from an aliphatic organic acid having 7 15 to 30 carbon atoms), and the mass ratio of (B)/(A) is 0.55 to 2.0.
Abstract:
A process for producing a pyrophosphate, particularly melamine pyrophosphate useful as a flame retardant, efficiently in high yield is provided. The process comprises firing an orthophosphate, preferably melamine orthophosphate, in the presence of a silicone oil, preferably methylphenyl silicone oil preferably at 120° to 350°C. Examples of useful firing equipment include a hot air dryer, a kneader, a Henschel mixture, a fluidized bed dryer, a rotary kiln, a paddle dryer, an extruder, a vibrating dryer, a far-infrared conveyor furnace, and a microwave firing furnace.
Abstract:
The invention provides a flame retardant composition that has excellent heat resistance and in which the risk of corroding processing machines at the time of compounding resin is reduced. Specifically, the invention provides a flame retardant composition comprising 20 to 50 parts by mass of component (A) described below, 50 to 80 parts by mass of component (B) described below (the total of the component (A) and the component (B) is 100 parts by mass), and 0.01 to 5 parts by mass of component (C) described below: component (A): at least one type of melamine salt selected from melamine orthophosphate, melamine pyrophosphate, melamine polyphosphate, or a mixture including two or more types of the melamine salts; component (B): at least one type of piperazine salt selected from piperazine orthophosphate, piperazine pyrophosphate, piperazine polyphosphate, or a mixture including two or more types of the piperazine salts; and component (C): a hydrotalcite compound.
