摘要:
The present invention provides a composite flame retardant which can be produced without using any toxic metal such as antimony trioxide or any halogen such as bromine and chlorine and can exhibit excellent flame retardancy compared with magnesium hydroxide when added in a smaller amount; and a flame retardant resin composition having excellent flame retardancy and excellent physical properties. The present invention relates to a flame retardant including: (A) 100 parts by mass of a reaction product of piperazine with one phosphorus compound selected from phosphoric acid, pyrophosphoric acid, and polyphosphoric acid; (B) 10 to 1000 parts by mass of a reaction product of melamine with a polyacid selected from cyanuric acid, phosphoric acid, pyrophosphoric acid, and polyphosphoric acid; and (C) 0.1 to 100 parts by mass of a reaction product of calcium or magnesium with silicic acid.

It is an object of the present invention to provide hydrotalcite which can inhibit a white discoloration by water of a polyolefin film for agricultural uses, a blooming to the surface of a vinyl chloride resin film, a reduction in electric resistance in the case of using the hydrotalcite as a stabilizer of a vinyl chloride resin for covering wires, the occurrence of die drool in the case of using the hydrotalcite as a neutralizer of an acid catalyst residue in a polyolefin resin or a copolymer thereof, and coloring (yellowing) in extrusion in preparing pellets and can be suitably used as a resin additive, a method of producing the same and a synthetic resin composition containing the same. Hydrotalcite expressed by the following formula (1); [(Mg)x(Zn)y]1-z(Al)z(OH)2(An−)z/n.mH2O (1) in the formula An− represents an anion having a valence of n, and x, y, z and m are values which satisfy the following expressions, 0.5≦x≦1, 0≦y≦0.5, x+y=1, 0.1≦z≦0.5, 0≦m

摘要:
The present disclosure provides powdery (poly)piperazine pyrophosphate that is not accompanied by difficult-to-remove byproducts and is not tinged with a color that would adversely affect the coloring of the molded article. The present disclosure also provides a method of producing such powdery (poly)piperazine pyrophosphate in an efficient manner and with a high yield. The present disclosure relates to a method for providing powdery (poly)piperazine pyrophosphate, which includes the step of dehydration condensation of piperazine diphosphate to prepare (poly)piperazine pyrophosphate. The step is performed under an inert gas atmosphere, and thereby powdery (poly)piperazine pyrophosphate having a whiteness of 80 to 100 as a W value, and a yellowness of 0 to 5 as a YI value is produced.
