いる。However, in the case of flame-retardant olefin resin compositions containing such halogen-based flame retardants, corrosive hydrogen halide gas is generated from the halogen-based flame retardants in the event of a fire, which has an adverse effect on the human body and equipment, so in recent years, Flame-retardant olefin resin compositions that do not generate hydrogen halide gas are being studied.

る。A common method for non-halogenating such flame-retardant olefin resin compositions is to fill the olefin resin with a large amount of inorganic hydrates such as aluminum hydroxide or magnesium hydroxide. Even though
The use of high-pressure ethylene/ethyl acrylate copolymer, which has a carbonization promoting effect and is more flame retardant, is being considered.

てはなお充分なものとはいえなかった。(Problem to be Solved by the Invention) However, in conventional flame-retardant olefin resin compositions filled with inorganic hydrates, the amount of inorganic hydrates is reduced by adding halogen-based flame retardants to obtain the necessary flame retardance. Since the amount must be 2 to 3 times larger than the amount of , there is a problem that the mechanical properties of the flame-retardant olefin resin composition deteriorate. In addition, high-pressure process ethylene/ethyl acrylate copolymer is more easily carbonized than other polyolefins, and therefore the amount of inorganic hydrate can be reduced, but the mechanical properties are still insufficient. I couldn't say yes.

(B) to 100 parts by weight of an olefin resin containing at least 40 parts by weight of a linear ethylene/ethyl acrylate copolymer (hereinafter referred to as L-EEA) with an ethyl acrylate content of 3 to 33%. The second invention is characterized in that 40 to 200 parts by weight of an inorganic hydrate is placed in the olefin resin.

It is characterized by containing at least one of 1 to 10 parts by weight of silicone gum of 1,000,000 C8 and 1=10 parts by weight of a selenium compound.

きくなるためである。The reason why the melt index at 190°C of L-EEA used in the present invention is limited as described above is that if it is less than 0.1, the processability will be poor, and if it exceeds 10, the mechanical properties will deteriorate. Furthermore, if the content of ethyl acrylate is less than 3%, the flame retardancy will be poor, and if it exceeds 33%, the mechanical properties will deteriorate significantly.

However, at least 40 parts by weight of 1 to 0 parts by weight of olefin resin is L-E.
EA. The reason for this is that if the amount is less than 40 parts by weight, it becomes difficult to improve mechanical properties.

なるのでいずれも好ましくない。Flame retardants used in the present invention include inorganic hydrates such as magnesium hydroxide, aluminum hydroxide, and hydrotalcite compounds, which are commonly used for non-halogen flame-retardant olefin resin compositions. The amount ranges from 40 to 200 parts by weight, preferably from 40 to 150 parts by weight, based on 100 parts by weight of the olefinic resin. If the blending amount of the inorganic hydrate is less than 40 parts by weight per 100 parts by weight of the olefin resin, the flame retardancy of the resin composition will be insufficient, and if it exceeds 200 parts by weight, the mechanical properties will become insufficient. I also don't like it.

．． 5 to 10 parts by weight, 1 to 10 parts by weight of silicone gum,
The reason for setting the selenium compound in the range of 1 to 10 parts by weight is that if it is less than the lower limit, flame retardance will be insufficient, and if it is more than the upper limit, processability will be impaired or mechanical properties will be insufficient. be.

In addition, when using this flame-retardant olefin resin composition as a coating for electric wires and cables, for example, the set temperature of the extruder should be adjusted to 1 at the cylinder position.
It is desirable that the temperature be 40°C or higher and 170 to 180°C at the die position.

小さく押えることができる。(Function) The flame-retardant olefin resin composition of the present invention uses L-EEA, which has a carbonization promoting effect as an olefin resin and has great mechanical properties, so it can be used even if a large amount of inorganic hydrate is blended. The degree of decrease in mechanical properties is small. In addition, when a flame retardant aid is used together with an inorganic hydrate, the same flame retardancy can be obtained even if the amount of inorganic hydrate added is significantly reduced by adding a small amount, and therefore the composition can be easily Deterioration in characteristics can be kept to a minimum.
