Description of the Related Art PVC compositions are widely used in wire coatings, tubes, tapes, packaging materials, building materials, etc. because of their good electrical insulation and self-extinguishing flame retardancy. However, since the PVC composition contains chlorine (Cl) which is a halogen, a corrosive gas such as HCl or a toxic gas such as dioxin is generated during combustion. Therefore, various PVC
If the product becomes waste, it is difficult to incinerate them. Therefore, at present, landfill disposal is performed.
Since a Pb-based stabilizer is often used as an additive in the composition, there is also a problem that the Pb-based stabilizer is eluted into soil or the like, and it is becoming difficult to treat it as industrial waste.

If a halogen-free polyethylene (PE) or polypropylene (PP) is used as a resin composition instead of
Since no harmful gas is generated during combustion, incineration is possible. However, these halogen-free resin compositions are made of PVC.
There was a defect that the flame retardancy was inferior to that of For example, when comparing the oxygen index (OI) which is one of the evaluation scales of the flame retardancy of the resin composition, the OI of PVC is 23 to 40, whereas the OI of PE and PP is about 17 to 19. It turns out that it is inferior. Therefore, in order to impart flame retardancy to a halogen-free resin composition such as PE or PP, it is usually practiced to add a metal hydrate such as Mg (OH) 2 or Al (OH) 3 thereto. Have been done. However,
The desired high flame retardancy may not be obtained with the metal hydrate alone, or if a large amount of the metal hydrate is added to obtain the desired high flame retardancy, properties such as mechanical properties may be significantly deteriorated.

As described above, the self-extinguishing flame retardancy equivalent to that of PVC can be realized, and a flame-retardant resin composition that is hardly burned in a fire and emits a small amount of smoke can be obtained. Further, since it does not contain halogen and does not generate toxic gas such as halogen gas at the time of combustion, it can be incinerated, and does not generate toxic gas at the time of fire.
In addition, since there is no elution of lead, landfill disposal is possible. Also,
By using a suitable combination of several types of flame retardants, it is possible to reduce the amount of magnesium hydroxide to be added and to suppress deterioration of mechanical properties. Therefore, high flame retardancy and good mechanical properties can be achieved at the same time. Further, by adding a silicone compound, the weather resistance of the resin can be improved. Conventionally, it is widely known to add carbon black to improve the weather resistance of a resin.However, when carbon black is added, the resin composition is colored black. Become. On the other hand, when a silicone compound is added, the weather resistance can be improved, and the resin does not become dark, so that a resin composition having good coloring properties can be obtained. Also, especially magnesium carbonate,
The use of silicon dioxide or zinc stannate effectively improves flame retardancy. This is thought to be because char formation during combustion is effectively promoted, and by preventing exposure of a new combustion surface, flame retardancy is improved.

A non-halogen flame-retardant resin composition having the same flame retardancy as VC and good mechanical properties and containing no halogen can be incinerated. According to the present invention, when used as a covering material for electric wires, cables or the like, among the combustion tests specified in the Electrical Appliance and Material Control Law, UL Standard, IEEE Standard 383, and IEC Standard 332-1, respectively. And thus a non-halogen flame-retardant resin composition having high practicality can be obtained.
