Problems solved by technology

However, since this flame-retardant resin composition contains about 30% by mass of melamine cyanurate as a flame retardant, and the total amount of inorganic substances is also about 70% by mass, there are problems not only in flame-retardant performance but also in There are also problems with processability and surface smoothness of molded products

Embodiment 1～15 and comparative example 1～4

[0114] 0.1 part by mass of calcium stearate, 0.3 part by mass of glycerol monostearate, tetrakis[3-(3,5-di-tert-butyl-4-hydroxyl 0.1 parts by mass of phenyl) methyl propionate] methane, 0.1 parts by mass of 2,2'-methylenebis(4,6-di-tert-butylphenyl)-2-ethylhexyl phosphite, using Henscher The thermoplastic polyurethane resin composition was obtained by pre-mixing with a Er mixer. The compositions shown in Table 1 or 2 were blended in parts by mass described in the table with respect to the obtained thermoplastic polyurethane resin composition, and mixed with a Henschel mixer to obtain a flame-retardant resin composition.

[0116]0.1 parts by mass of calcium stearate (higher fatty acid metal salt), tetrakis[3- (3,5-di-tert-butyl-4-hydroxyphenyl) methyl propionate] methane (phenolic antioxidant) 0.1 parts by mass, tris (2,4-di-tert-butylphenyl) phosphite (phosphorus 0.1 parts by mass of an antioxidant) were premixed with a Henschel mixer to obtain a polypropylene resin composition. The compositions shown in Table 1 or Table 2 were blended in parts by mass described in the table with respect to the obtained polypropylene resin composition, and mixed with a Henschel mixer to obtain a flame-retardant resin composition.

[0117] Each of the resin compositions obtained above was prepared into pellets by the following method, and a test piece for flame retardancy evaluation was prepared from the pellets, and the evaluation piece was used for the following flame retardancy evaluation and surface smoothness evaluation. The results are shown in Table 1 and Table 2.

Abstract

The composition according to the present invention contains (A) an amine phosphate, and (B) melamine cyanurate. In the composition according to the present invention, the component (A) preferably contains (A-1) and (A-2). Component (A-1): at least one melamine salt selected from the group consisting of melamine orthophosphate, melamine pyrophosphate, and melamine polyphosphate. Component (A-2): atleast one piperazine salt selected from the group consisting of piperazine orthophosphate, piperazine pyrophosphate, and piperazine polyphosphate. The present invention can provide a composition which, when blended with a resin, imparts to the resin a dripping prevention effect and superior flame resistance, and can allow production of a molded article having good surface smoothness.

Description

technical field [0001] The present invention relates to a composition comprising amine phosphate and melamine cyanurate, 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 aids are well kn...
