Problems solved by technology

However, the flame retardant effect produced by adding metal hydroxide is small, and the desired flame retardancy is often not obtained, so the addition amount of metal hydroxide is increased
Along with this, the viscosity of the resin composition increases, and the load on the extruder increases when producing wires and cables, and the workability (extrusion speed, etc.) is poor compared to the resin composition that does not contain halides.

Embodiment 1

[0064] When the addition amount of magnesium hydroxide in Examples 1 and 2 was changed to 150 parts by weight (Example 1) and 300 parts by weight (Example 2), the tensile properties (elongation) when the addition amount of magnesium hydroxide increased deterioration, so it is preferable that the added amount of magnesium hydroxide is less than 300 parts by weight.

[0065] In Example 4 of magnesium hydroxide without solid-solution nickel and Example 5 of solid-solution nickel, the flame retardancy of solid-solution nickel is improved, which is suitable.

[0066] In addition, in Example 7 in which the 1,3,5-triazine derivative was changed to melamine sulfate, and in Example 8 in which melamine cyanurate was changed, no difference in characteristics was observed, and both were good. In addition, in Examples 8 and 9 in which a fatty acid metal salt and a fatty acid amide were used in combination, the characteristics were good.

[0067] On the other hand, Comparative Examples 1-8...

Abstract

The objective of the present inventin is to provide a hal free fire resistant resin composition as well as wires and cables using same. Said fire resistant resin composition possesses the following performances: no performances degeneration occurs when metal hydroxides are added into polyolefine resins; the resin composition has low viscosity, with excellent constructional properties. Relative to100 parts by weight of polyolefine resins, said hal free fire resistant resin composition contains 150-300 parts by weight of metal hydroxides, 20-50 parts by weight of 1,3,5-triazine derivatives, 0.1-5 parts by weight of fatty salts(metal)and 0.01-1 parts by weight of fattiness acidamide.

Description

technical field [0001] The present invention relates to a halogen-free flame-retardant resin composition and an electric wire and cable using the same. Background technique [0002] As a flame-retardant resin composition not containing a halide, a composition obtained by adding a metal hydroxide such as magnesium hydroxide or aluminum hydroxide to a polyolefin-based resin is used. Since these compositions do not generate toxic gases such as hydrogen chloride or dioxin during combustion, they can prevent the generation of toxic gases during fires or prevent secondary disasters, etc., and no problems will occur even if they are incinerated when they are discarded. However, the flame retardancy effect by adding the metal hydroxide is small, and the desired flame retardancy is often not obtained, so the added amount of the metal hydroxide is increased. Along with this, the viscosity of the resin composition increases, and the load on the extruder increases when producing electr...
