Problems solved by technology

However, since the flame-retardant synthetic resin composition described in Patent Document 1 contains a fluorine-based anti-dripping agent, the original physical properties of the resin may be impaired.
[0004] In addition, even if a fluorine-based anti-dripping agent is not used, if the content of the flame retardant is large, there is a problem that the original physical properties of the resin will be impaired, and the mass of the entire resin composition will increase, which is not preferable from the viewpoint of energy saving. , a lightweight resin composition with a low flame retardant content is required

Embodiment 1～4 and comparative example 1～12

[0107] According to the ingredients described in the following Tables 1 and 2, a flame-retardant polypropylene composition was prepared, and then the flame-retardant polypropylene composition was extruded at 200 to 230°C to produce pellets, and the obtained pellets were used Injection molding was performed at 200° C. to obtain a test piece with a length of 127 mm, a width of 12.7 mm, and a thickness of 1.6 mm. Using this test piece, a UL-94V test was performed as a flame retardancy test by the following test method. The results are shown in Tables 1 and 2.

[0108] In addition, the mass and volume of the test piece of Example 2 were measured, and the density of the molded body was calculated by calculation. The results are shown in Table 1.

[0109] In the same manner, comparative examples were carried out according to the formulations described in Tables 1 and 2. In Comparative Examples, homopolypropylene and block copolymer polypropylene were used instead of the random co...

Abstract

This flame-retardant polypropylene composition contains a random copolymer polypropylene as a synthetic resin component and contains the following component (A) and component (B) as flame-retardant components. Said composition preferably also contains component (C), zinc oxide, as a flame-retardant component. A styrene-based thermoplastic elastomer is also preferably contained as a synthetic resin component. Component (A): one or more melamine salts selected from the group consisting of melamine orthophosphate, melamine pyrophosphate, and melamine polyphosphate. Component (B): one or more piperazine salts selected from the group consisting of piperazine orthophosphate, piperazine pyrophosphate, and piperazine polyphosphate

Description

technical field [0001] The present invention relates to a flame-retardant polypropylene composition (may also be referred to as a flame-retardant polypropylene resin composition) excellent in flame retardancy without impairing the original physical properties of the resin. Background technique [0002] Polypropylene resin has the advantages of excellent molding processability, heat resistance, and mechanical properties, as well as low specific gravity and light weight, and is widely used in various molded products such as films, sheets, and structural parts. In addition, reduction in the weight of synthetic resin molded products is being demanded in automotive applications, which require reduction in product transportation costs and improvement in fuel efficiency. Since this polypropylene resin is flammable, it is necessary to add a flame retardant to impart flame retardancy. [0003] As the flame retardant, the intumescent flame retardant has excellent flame retardancy. It...
