Embodiment 1～6 and comparative example 1～4

[0125] (A) component and (B) component were produced by the following method.

manufacture example 1

[0127] (A) Ingredient: Melamine salt

[0128] Melamine orthophosphate was heated and condensed in a solid state at 220° C. for 6 hours to produce a melamine salt mainly composed of melamine pyrophosphate. The melamine salt was used directly without refining. The purity of melamine pyrophosphate in the melamine salt is 98.5%.

[0129] The purity was determined by using an HPLC device (pump; SSC-3150, RI detector; ERC-7515A) manufactured by Senshu Science Co., Ltd., a column oven (CO-965) manufactured by JASCO Corporation, and an OHpak column (SB-802.5HQ) manufactured by Shodex Corporation. Determination.

manufacture example 2

[0131] (B) Ingredient: piperazine salt

[0132] Piperazine orthophosphate was heated and condensed in a solid state at 250° C. for 1 hour to produce a piperazine salt mainly composed of piperazine pyrophosphate. The piperazine salt was used directly without purification. The purity of piperazine pyrophosphate in the piperazine salt was 99.0%.

[0133] The purity was determined by using an HPLC device (pump; SSC-3150, RI detector; ERC-7515A) manufactured by Senshu Science Co., Ltd., a column oven (CO-965) manufactured by JASCO Corporation, and an OHpak column (SB-802.5HQ) manufactured by Shodex Corporation. Determination.

[0134] Next, the flame retardant composition of the example was adjusted according to the formulation described in Table 1. Similarly, the flame retardant composition of the comparative example was adjusted according to the formulation described in Table 1.

[0135] In addition, the pH of the flame retardant composition obtained above was measured by the...

Abstract

The present invention provides a flame-retardant composition having excellent heat resistance and reduced risk of corroding processing equipment during resin compounding, specifically a flame-retardant composition containing 20-50 parts by mass of component (A), 50-80 parts by mass of component (B) (where the total of component (A) and component (B) is 100 parts by mass), and 0.01-5 parts by mass of component (C). Component (A): one or more melamine salts selected from melamine orthophosphate, melamine pyrophosphate, melamine polyphosphate, and mixtures containing two or more of these melamine salts. Component (B): one or more piperazine salts selected from piperazine orthophosphate, piperazine pyrophosphate, piperazine polyphosphate, and mixtures containing two or more of these piperazine salts. Component (C): hydrotalcite compound.

Description

technical field [0001] The present invention relates to a flame retardant composition for synthetic resins and a flame retardant synthetic resin composition containing the flame retardant composition, in particular, to excellent heat resistance and reduced risk of corrosion of processing equipment during resin compounding The prepared flame retardant composition and the flame retardant synthetic resin composition with excellent weather resistance are compounded with the flame retardant composition. Background technique [0002] Conventionally, synthetic resins have been widely used in building 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. In addition, as a flame retarding method, it is widely known to use a halogen flame retarda...
