ビニル（ＰＣＶ）が一般的に用いられている。2. Description of the Related Art For example, polyvinyl chloride (PCV) is generally used as a covering material for electric wires because it is easy to obtain a material suitable for the purpose of use.

合させたものが挙げられる。However, since polyvinyl chloride is a halogen-containing polymer, there has been a problem that harmful gases such as hydrogen chloride are generated during combustion. Therefore, it has been required to provide a non-halogen flame-retardant coating material that does not generate harmful hydrogen halide gas.
Examples of the non-halogen flame-retardant coating material include a mixture of an olefin resin and a metal hydroxide serving as a non-halogen flame retardant.

てしまうという問題点があった。By the way, when an olefin resin is mixed with a metal hydroxide serving as a non-halogen flame retardant, the flexibility is inferior to that of polyvinyl chloride. there were. Moreover, in order to ensure the required flame retardancy, it is necessary to incorporate a large amount of a metal hydroxide as a flame retardant, so that there is a problem that the wear resistance is affected.

失われてしまうという別な問題点が生じてしまった。In order to ensure wear resistance, it is conceivable to harden the coating material, increase the thickness of the coating material, or perform electron beam crosslinking, chemical crosslinking, or the like. However, if a method of increasing the thickness of the hard material or the coating layer is adopted, another problem occurs in that the coated electric wire becomes very hard and affects the handling. In addition, if a coping method by bridging is adopted, the productivity of the coated electric wire is reduced, a large facility is required, the production cost is affected, and the flexibility is lost. Another problem has arisen.

When the amount of wax is less than 0.5 part by weight, the effect of abrasion resistance (scratch resistance) is low. When the amount of wax is more than 5 parts by weight, there is too much slipping effect to make processing impossible. This is because there is fear. Further, the reason why the liquid paraffin is 0.5 to 10 parts by weight is that the liquid paraffin is 0.1 to 10 parts by weight.
If the amount is less than 5 parts by weight, the effect of flexibility is reduced. If the amount exceeds 10 parts by weight, the tensile strength may be affected. Furthermore, the reason why the sum of the wax and the liquid paraffin is 2.5 to 11 parts by weight is that the effects of abrasion resistance (scratch resistance) and flexibility are taken into consideration.

適に用いることができる。Since the flame-retardant resin composition of the present invention has the above-mentioned composition, it is possible to suppress the damage particularly by the compounded wax. Also,
The blended wax and liquid paraffin can also provide flexibility. That is, with respect to the abrasion resistance (scratch resistance), the filler (flame retardant), which should be exposed on the surface of the flame retardant resin composition, is protected by the wax and is prevented from being whitened by an external impact. Will be able to Further, regarding the flexibility, since the liquid paraffin exists around the filler protected by the wax, the lubrication can be maintained. In other words, the sliding effect of the wax and the lubricity of the liquid paraffin can provide flexibility. Therefore, according to the present invention, it is possible to provide a flame-retardant resin composition that ensures abrasion resistance (scratch resistance) and flexibility. Thereby, it can be suitably used for coating materials such as electric wires and cables, hoses, sheets, injection molded products, and the like.
