【発明の属する技術分野】
本発明は、高度な難燃性を有し、燃焼時にハロゲン等の有害ガスの発生が少なく、さらに長期にわたり帯電防止性を有し、かつ耐熱性に優れ、パイプ、電線被覆、Tダイやインフレーション等の押出成形性および射出成形性等の加工性に優れ、かつ着色性に優れたポリオレフィン系樹脂相当の柔軟性を有する樹脂組成物に関する。
【0002】
【従来の技術】
従来、ポリオレフィン系樹脂等の可燃性樹脂の難燃化は、ハロゲン含有化合物と三酸化アンチモンを併用して配合することがよく知られている。また、燃焼時にハロゲンガス等の発生が少ないよう、水酸化マグネシウム等の水和金属化合物を多量に添加する配合あるいは赤燐を添加し難燃性を向上することが知られている。また、ナイロン66/6共重合体にシアヌル酸メラミンを添加し難燃化する方法がしられている(特公昭58−42218)。また、樹脂自体が難燃性を有するポリフェニレンサルファイド等のエンジニアリングプラスチックがある。
【0003】
【発明が解決しようとする課題】
しかしながら、ハロゲン含有化合物で難燃化したものは、燃焼時にハロゲン等の有害ガスを発生するという欠点があり、用途が限定される。金属水和物で難燃化したものは、有害ガスの発生は少ないものの、ハロゲン含有化合物を使用した場合のような高度な難燃性を得ることができない。また、難燃性を向上するために金属水和物に赤燐を添加する処方が知られているが、赤燐が赤褐色を呈しているため着色に制限がある。また、ポリオレフィンの融点はポリプロピレンを除き、融点が140℃以下のものが殆どであり、高温での使用に制限がある。ナイロン66/6共重合体にシアヌル酸メラミンを添加したものやポリフェニレンサルファイド等のエンジニアリングプラスチックは、難燃性に優れ、ハロゲンガス等の発生がなく、耐熱性に優れるものの柔軟性がなく、ポリオレフィン系樹脂相当の柔軟性が得らず、かつポリオレフィンに比較し極端に耐寒性に劣る。
【0004】
本発明は、上記従来の問題点を解消し、高度な難燃性を有し、かつ燃焼時のハロゲン等の発生がなく、Tダイやインフレーション、電線やパイプ押出等の加工性に優れ、耐熱性に優れ、かつ着色性に優れたポリオレフィン系樹脂相当の柔軟性を有する樹脂組成物およびその成形物を提供することを課題とする。

The present invention relates to a resin composition having flexibility equivalent to a polyolefin-based resin excellent in processability such as extrusion moldability and injection moldability and the like, and excellent in colorability.
[0002]
[Prior art]
Conventionally, it is well known that flame retardant resins such as polyolefin resins are compounded using a halogen-containing compound and antimony trioxide in combination. It is also known to improve the flame retardancy by adding a large amount of a hydrated metal compound such as magnesium hydroxide or red phosphorus so that the generation of halogen gas or the like is reduced during combustion. Moreover, the method of making a flame-retardant by adding melamine cyanurate to nylon 66/6 copolymer is made (Japanese Patent Publication No. 58-42218). In addition, there are engineering plastics such as polyphenylene sulfide in which the resin itself has flame retardancy.
[0003]
[Problems to be solved by the invention]
However, those flame-retarded with halogen-containing compounds have the disadvantage of generating harmful gases such as halogens during combustion, and their use is limited. A flame retardant made of a metal hydrate does not generate a high degree of flame retardancy as in the case of using a halogen-containing compound, although the generation of harmful gases is small. Moreover, although the prescription | regulation which adds red phosphorus to a metal hydrate in order to improve a flame retardance is known, since red phosphorus is exhibiting reddish brown, there exists a restriction | limiting in coloring. Further, the melting point of polyolefin is almost the one with a melting point of 140 ° C. or less except for polypropylene, and the use at high temperature is limited. Nylon 66/6 copolymer added with melamine cyanurate and engineering plastics such as polyphenylene sulfide have excellent flame resistance, no generation of halogen gas, etc. The flexibility equivalent to resin is not obtained, and it is extremely inferior in cold resistance compared to polyolefin.
[0004]

It can be set as this molded object .
[0011]

[0024]
Example 1-7 and Comparative Example 1-19
After mixing by the tumbler with the components and blending ratios described in Table 1 to Table 7 , the mixture was melt-kneaded with a 30 mmφ twin-screw vent extruder and pelletized. The pellet was T-die molded to prepare a 200 μm film. However for those molded impossible heating two-roll and hot press, thereby producing a molded sample by cooling press. The pellet heating two roll and hot press, thereby producing 0.3 mm, 1mm, the 2mm and 3mm sheet molded by a cooling press. Further, a 0.48φφ copper wire was coated with 0.18 mm by an electric wire extruder to produce an electric wire. Evaluation of each characteristic was performed in the following manner, evaluation results were described together in Table 1-7.
[0025]
(1) Flammability 1: UL94 vertical combustion test was conducted at a thickness of 3 mm.
(2) Combustibility 2: UL94 vertical combustion test was conducted on a 200 μm thick film.
(3) Flammability 3: Executed in accordance with JIS C 3005 horizontal and tilt tests. However, the inclination angle was 30, 45, and 60 degrees.
(4) Formability: The formability at the time of wire coating was evaluated by appearance (visually).
(5) Surface resistance: The surface resistance after standing for 24 hours at 23 ° C. and 55% humidity was measured.
(6) Heat resistance: A 3 mm thick sheet was cut into a width of 2.5 cm and a length of 10 cm, suspended in a 150 ° C. oven for 1 hour with a clip, and the presence or absence of melting and dropping was confirmed.

(8) Tensile elongation: According to JIS K 6760. A 1 mm thick sheet was used and measured at a tensile speed of 200 mm / min.
[0026]
As apparent from Table 1 to Table 7 , by adding 10% or more of the component (B) to the component (A), V-2 to V-0 equivalent at a thickness of 3 mm and VTM-2 to VTM- at a thickness of 200 μm. Flame retardant properties corresponding to 0 can be obtained. In particular, when the component (B) is 55% or more, flame retardancy equivalent to V-0 can be obtained. In addition, when the component (B) is 10% or more, it is suitable for horizontal combustion, when it is 30% or more, it is suitable for a 30-degree inclination test, when it is 50% or more, it is suitable for a 45-degree inclination test, and when it is 60% or more, 60 Suitable for degree tilt test.

Further, when 20% or more of the component (C) is added, deformation occurs during extrusion processing.
[0029]
Even if the component (B) is added to polyethylene or ethylene-vinyl acetate copolymer, flame retardancy equivalent to V-0 or high flame retardancy by an electric wire inclination test cannot be obtained. Further, when the component (C) is added, a bleed phenomenon occurs and high flame retardancy cannot be obtained. Moreover, the plasticizer effect by addition of (C) component is also not recognized. Also, no antistatic effect is observed.
