FIELD OF THE INVENTION The present invention relates to flame-retardant poly-α-olefin resin compositions. Conventionally, poly-α-olefin resins have been made flame-retardant using halogen-based flame retardants, but this generates corrosive gases such as hydrogen halides when burned, and can damage expensive equipment in the event of a fire. In addition to being corrosive, they were also toxic and could cause poisoning accidents. In recent years, a method using inorganic compounds containing water of crystallization has been proposed as a flame retardant method that does not generate toxic and corrosive gases during combustion. If the poly-α-olefin resin is relatively highly crystallized, it will melt and the viscosity will drop significantly, resulting in a dripping phenomenon. An object of the present invention is to provide a poly-α-olefin resin composition that has excellent flame retardancy and can prevent dripping during combustion. The gist of the present invention is that polyα-olefin resin 100
30 to 250 parts by weight of aluminum hydroxide
5 to 50 parts by weight of hydrotalcite or dowsonite. The above-mentioned poly-α-olefin resin composition is composed of an ethylene-containing polymer such as a copolymer of polyethylene, polypropylene, polybutene ethylene and other copolymerizable substances, or a blend thereof. It also includes chemical compounds. Aluminum hydroxide is used to eliminate the flame retardant disadvantage of polyα-olefin resins and improve the flame retardancy of the composition. Aluminum hydroxide has a high thermal decomposition temperature and does not undergo thermal decomposition during the process of melting and growing the composition according to the present invention by heating, so there is a risk that it will thermally decompose during molding and lose its flame retardant effect. There is no
It is also used because it has excellent miscibility with polyα-olefin resins. The amount used is 30 to 250 parts by weight per 100 parts by weight of polyα-olefin resin. In this case, if the amount is less than 30 parts by weight, the effect of imparting flame retardance will be reduced, and if the amount is more than 250 parts by weight, the molded product formed using the composition according to the present invention will be There is a noticeable tendency to reduce mechanical strength. However, in the present invention, by blending 30 to 250 parts by weight of aluminum hydroxide with 100 parts by weight of polyα-olefin resin, flame retardancy is imparted to the composition. Since the olefin resin has a relatively high degree of crystallinity when exposed to a high-temperature flame, it melts and its viscosity decreases significantly, causing a dripping phenomenon. In the present invention, 5 to 20 parts by weight of hydrotalcite or dowsonite is further added in order to obtain a composition that not only has flame retardancy but also does not cause the drip phenomenon. Hydrotalcite is a white fine powder represented by 6MgO.Al 2 O 3 .H 2 O, and dowsonite is
It is a white fine powder represented by NaAl(OH) 2 CO 3 or Al(OH) 2 .Na 2 CO 3 XH 2 O. Hydrotalcite and dowsonite may be used alone or in combination. Therefore, even if hydrotalcite and dowsonite are used alone or in combination, polyα-olefin resin 100
These components are used in amounts ranging from 5 to 50 parts by weight. Therefore, if the amount is less than 5 parts by weight, the effect of preventing the melt dripping phenomenon will not be sufficiently exhibited, and if the amount is more than 50 parts by weight, the miscibility with the polyα-olefin resin will not be sufficient. First, it is difficult to form a uniform composition, and in order to prevent melting and dripping phenomena, it is not necessary to use a larger amount than this part by weight. In the present invention, in addition to these components, lubricants, antioxidants, ultraviolet absorbers, colorants, fillers, etc. may be used as necessary. Furthermore, poly-α-olefin resin can be easily crosslinked using peroxide and energy-rich radiation, and the composition of the present invention can also be easily crosslinked by the above method, thereby further improving chemical resistance, etc. You can improve. Examples of the present invention are shown below along with comparative examples. (Amounts are parts by weight)
