Problems solved by technology

However, in the composition described in this document, since the heat-resistant temperature of pentaerythritol dimer used as a carbonizing agent is low, there is a problem that the volatility during combustion becomes high, and the safety during combustion is impaired.
In addition, the content of aluminum hydroxide, which is an inorganic substance, is large, and there is a problem in formability during processing.

Abstract

A composition according to the present invention contains component (A), component (B), and component (C) below, wherein component (A)is at least one melamine salt selected from the group consisting of melamine orthophosphate, melamine pyrophosphate, and melamine polyphosphate; component (B)is at least one piperazine salt selected from the group consisting of piperazine orthophosphate, piperazinepyrophosphate, and piperazine polyphosphate; and component (C)is a monohydrate of alumina. According to the present invention, a composition is provided, which, when mixed with a resin, can impart excellent processability and moldability and flame retardancy to the resin.

Description

technical field [0001] The present invention relates to a composition comprising a phosphate of piperazine and a phosphate of melamine, and a flame-retardant resin composition containing the composition. Background technique [0002] Conventionally, synthetic resins have been widely used in construction materials, automobile parts, packaging materials, agricultural materials, casing materials for home appliances, and toys due to their excellent chemical and mechanical properties. However, most synthetic resins are combustible, and flame retardancy is indispensable depending on the application. As a flame retardant method, halogen-based flame retardants, inorganic phosphorus-based flame retardants represented by polyphosphate-based flame retardants such as red phosphorus and ammonium polyphosphate, organic flame retardants represented by triaryl phosphate compounds, etc. Phosphorous flame retardants, metal hydroxides or antimony oxide, melamine compounds as flame retardant a...
