Problems solved by technology

[0005] However, the above-mentioned conventional intumescent flame retardants generate dust during use, and their handling properties have not been sufficiently solved, and even if the dust can be improved, caking occurs during storage, and storage stability is problematic. There is also a problem of adversely affecting flame retardancy

Embodiment 1～9 and comparative example 1～7

[0173] According to the compounding ratio described in Table 1, each component was mixed for 20 minutes at the rotation speed of 1500 rpm / min using the Henschel mixer, and the flame retardant composition powder of Examples 1-9 was prepared. (D) As an aliphatic dicarboxylic acid ether ester compound represented by the said general formula (1) of a component, compound No. 1 of the following structure was used.

[0174]

[0175] Similarly, flame retardant composition powders of Comparative Examples 1 to 7 were prepared according to the proportions described in Table 2. In the comparative example, in order to compare with the silane coupling agent of the component (C) of the example, the comparative example using silicone oil was implemented, and in order to compare with the compound No. 1 of the component (D) of the example, the use of glycerin was implemented. Comparative example of monostearic acid ester.

Abstract

The invention provides a flame retardant composition containing: component (A), which is 20-50 parts by mass of one or more melamine salts selected from the group of melamine orthophosphate, melamine pyrophosphate, and melamine polyphosphate; component (B), which is 50-80 parts by mass of one or more piperazine salts selected from the group of piperazine orthophosphate, piperazine pyrophosphate, and piperazine polyphosphate (where the total of component (A) and component (B) is 100 parts by mass); component (C), which is 0.01-5.0 parts by mass of a silane coupling agent; and component (D), which is 0.01-1.0 part by mass of an aliphatic dicarboxylic acid ether ester compound represented by general formula (1). Formula (1) is described in detail in the specification.

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. Specifically, it has less dust, excellent handling properties, and stable storage without caking. A flame retardant composition with excellent properties and a flame retardant synthetic resin composition blended with the flame retardant composition. Background technique [0002] Conventionally, synthetic resins have been widely used in building materials, automobile parts, packaging materials, agricultural materials, housing 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, the following methods are widely known as flame retardant methods: use of halogen-based flame retardants alone or in combination, ...
