Abstract
The present invention relates to a polyphenylene oxide-based flame-retardant insulating material which does not contain any flame retardant and which has mechanical properties and flame retardancy harmonized, and an insulated wire using the same. The flame-retardant insulating material of the present invention comprises 0.2 to 10 parts by weight of a lubricant and 0.2 to 10 parts by weight of a stabilizer based on 100 parts by weight of a base resin comprising 30 to 90% by weight of modified polyphenylene oxide and 10 to 70% by weight of a polyolefin, The modified polyphenylene oxide comprises 10 to 50% by weight of polyphenylene oxide and 50 to 90% by weight of at least one rubber component selected from high impact polystyrene and styrene-ethylene-butylene-styrene (SEBS) rubbers.
Description
The present invention relates to a flame-retardant insulating material and an insulated wire using the same. More particularly, the present invention relates to a non-halogen polyphenylene oxide-based insulating material.
Polyolefins containing polyvinyl chloride or flame retardants have been widely used as flame retardant materials for insulating layers of electric wires because of their excellent mechanical properties and low cost. However, halogen-containing polyolefins such as polyvinyl chloride and halogen-based flame retardants emit poisonous gases such as dioxins during combustion. Recently, regulations for use of flame-retardant insulating materials including halogen elements such as PVC have been strengthened It is true. Also, as an alternative to the halogen-based flame-retardant insulating material, a method of mixing a metal hydroxide-based inorganic flame retardant with a non-halogen polyolefin has been popular. However, in this case, the thermal stability of the metal hydroxide component is lowered at the processing temperature of the polymer resin, and the mechanical properties are deteriorated rapidly. In addition, when a filler is introduced to prevent deterioration of mechanical properties when a metal hydroxide is used, an excess amount of the filler is required to increase the viscosity of the polymer resin containing the filler, resulting in poor processability.
Therefore, development of an economical halogen-free flame retardant resin composition having sufficient flame retardancy and good mechanical properties and processability is still a field that needs constant research.
The technical problem of the present invention is to develop a highly flame-retardant insulating material which does not contain a halogen component and has mechanical properties such as flexibility and elongation, processability and economy.
In order to achieve the above object, in the present invention, 0.2 to 10 parts by weight of a lubricant and 0.1 to 10 parts by weight of a stabilizer are added to 100 parts by weight of a base resin composed of 30 to 90% by weight of modified polyphenylene oxide and 10 to 70% 0.2 to 10 parts by weight of a composition. Wherein said modified polyphenylene oxide is a mixture of 10-50 wt% of polyphenylene oxide and 50-90 wt% of at least one rubber component selected from high impact polystyrene and styrene-ethylene-butylene-styrene (SEBS) . As the polyolefin, a non-modified polyolefin may be used, or a polarized polyolefin to which a polar functional group is introduced may be used.
The present invention also provides an insulated electric wire in which an insulating layer is produced using such a flame-retardant insulating material.
The electric wire obtained by using the flame-retardant insulating material of the present invention has excellent flame retardancy, for example, vertical flame retardancy according to UL 1581 standard and excellent mechanical properties. Further, the insulating layer can be completed without a crosslinking step, and there is an advantage that a less expensive component can be used. And it can have a smooth appearance like a polyolefin-based insulating material, so that there is an advantage that work line speed is improved during manufacturing of electric wire.
Hereinafter, the present invention will be described in detail. The flame-retardant insulating material of the present invention contains a lubricant and a stabilizer in a base resin composed of polyphenylene oxide (PPO), a rubber resin, and a polyolefin, and exhibits a flame retardant effect even without a separate flame retardant.
The polyphenylene oxide (PPO) polymer including poly (2,6-dimethylphenylene oxide) is easy to form a char, and therefore has excellent flame retardancy, high mechanical strength and high heat resistance. PPO, on the other hand, is brittle and has a drawback that it is difficult to process. Therefore, if an insulating material capable of mixing a polyphenylene oxide having excellent flame retardancy with another polymer and having excellent mechanical properties and processability and omitting the crosslinking step can be produced, it is very preferable as an insulating layer of electric wires.
In the present invention, a polyolefin is mixed with a modified polyphenylene oxide containing a rubber resin so as to obtain a flame retardancy and a mechanical strength as well as a smooth surface in a wire insulation layer. In the insulating material of the present invention, the base resin is composed of 30 to 90% by weight of modified polyphenylene oxide and 10 to 70% by weight of polyolefin.
As the polyphenylene oxide which can be used in the present invention, it is suitable to use polyphenylene oxide type polymer commonly used in this field including poly (2,6-dimethylphenylene oxide).
In the present invention, the term "modified polyphenylene oxide" means a mixture of polyphenylene oxide and a rubber resin (elastomer). In this field, what is referred to as a modified polyphenylene oxide is already commercially available as a mixture of polyphenylene oxide and a rubber resin. It goes without saying that such commercially available modified PPO can be used in the present invention as a base resin. High impact polystyrene (HIPS), styrene-ethylene-butylene-styrene (SEBS) rubbers, polyolefin elastomers, and the like are some examples of rubber resin components included in the modified polyphenylene oxide. Of these, more preferred rubber resin components are high impact polystyrene (HIPS), styrene-ethylene-butylene-styrene (SEBS) rubber, and mixtures thereof. If polyphenylene oxide is mixed with high impact polystyrene and / or SEBS rubber, the flexibility and elongation of insulation material can be improved. Here, the polyphenylene oxide may have a melt flow index of 5 to 50 (220 ° C, 10 kg, 10 minutes), and the high-impact polystyrene may have a styrene content of 30 to 70% by weight and a melt flow index of 0.1 - Wherein the styrene-ethylene-butylene-styrene rubber has a styrene content of 30 to 70% by weight and a melt flow index of 0.1 to 30 (190 DEG C, 2.16 kg, 10 Min).
As the modified polyphenylene oxide in the insulating material of the present invention, a mixture of 10 to 50% by weight of polyphenylene oxide and 50 to 90% by weight of a rubber resin such as high impact polystyrene and / or SEBS rubber is used. When the content of the polyphenylene oxide and the rubber resin is within this range, it is advantageous to maintain appropriate mechanical strength as a wire material and to have flexibility and workability. If the content of the polyphenylene oxide is less than 10% by weight in the modified polyphenylene oxide, the mechanical strength and the flame retardancy are inferior and the polyphenylene oxide is not suitable as a material for the wire. If the content of the polyphenylene oxide exceeds 50% by weight, It is difficult to use because of its characteristics.
In the present invention, the polyolefin improves the surface characteristics by smoothing the appearance of the wire and improves workability in the extrusion production process, thereby improving the productivity and further improving the flexibility and elongation. Further, the polyolefin is less expensive than other components such as polyphenylene oxide, so that the unit cost of the raw material can be lowered.
Examples of the polyolefin which can be used as a component of the insulating material include polyethylene, low density polyethylene, linear low density polyethylene, high density polyethylene, polypropylene, ethylene-propylene copolymer, ethylene-1-octene copolymer, ethylene- Alpha-olefin-ethylene block copolymers containing from 1 to 15 carbon atoms, alpha olefin-ethylene random copolymers containing from 3 to 15 carbon atoms, ethylene-vinyl acetate copolymers having a vinyl acetate content of from 2 to 40% And an ethylene-ethyl acrylate copolymer having a content of 2 to 40%.
As such a polyolefin resin, those having a melt flow index in a range commonly used as a wire insulation material in this field can be used. More specifically, it is more preferable to use a melt flow index of 0.1 to 10. When the physical quantity is within this range, it is advantageous to maintain proper mechanical properties after machining as well as machining characteristics. If the melt flow index of the polyolefin is less than 0.1, the load during extrusion processing is too high to maintain proper processing characteristics. On the other hand, when the melt index is less than 10, Should be avoided.
In the insulating material of the present invention, the base resin contains 30 to 90% by weight of the modified polyphenylene oxide and 10 to 70% by weight of the polyolefin. When the polyolefin is contained in the base resin in the above ratio, the productivity of the production process is improved, and the elongation and flexibility of the insulating material are improved. If the content of the polyolefin in the base resin is less than 10% by weight, the flexibility is deteriorated and the processing characteristics are inferior. If the content exceeds 70% by weight, the mechanical properties and flame retardancy are deteriorated.
In the base resin of the present invention, as the polyolefin, only untreated unmodified polyolefin may be used. Alternatively, a polarized polyolefin having a polar functional group introduced into the unmodified polyolefin may be used, or a mixture of a polyolefin having no compatibility and polarity may be used. When a polarized polyolefin having a polar functional group is used in the base resin, a chemical bond with polyphenylene oxide is formed and the mechanical strength is increased, which is preferable. Introduction of functional groups to the unmodified polyolefin for polarization can be accomplished by treatment of the unmodified polyolefin with a material such as, for example, maleic anhydride, maleic anhydride or glycidyl methacrylate. For example, a maleic anhydride may be grafted onto a non-modified polyolefin to introduce a carboxyl group or a carboxylic acid anhydride into the polyolefin chain.
Methods for treating such polyolefins with polarizations are well known in the art and are not described in detail herein. Briefly, such treatment is preferably carried out by treating (for example, grafting) the polar group-introduced material (for example, maleic anhydride) in a proportion of 0.1 to 5 parts by weight based on 100 parts by weight of the polyolefin.
As the unmodified polyolefin or the polarized polyolefin used in the base resin of the present invention, it is preferable to use a polyolefin having a melt flow index of 0.1 to 10 in terms of securing mechanical strength and processability.
The insulating material of the present invention further includes a lubricant and a stabilizer in addition to the base resin. The lubricant enhances the releasability of the insulating material from the metal on the surface of the manufacturing machine and can suppress the generation of frictional heat. There is no particular limitation on the lubricant that can be used in the resin composition of the present invention, and it is acceptable to use a lubricant conventionally used in this field. Some examples are low molecular weight polyethylene, stearic acid, stearyl alcohol, butyl stearate, wax, and the like. The content of the lubricant is suitably 0.2 to 10 parts by weight based on 100 parts by weight of the base resin. When the content of the lubricant is less than 0.2 parts by weight, the lubricating effect is not exhibited. When the amount of the lubricant is more than 10 parts by weight, kneading becomes difficult, which may deteriorate the physical properties of the whole resin composition.
In the present invention, an antioxidant may be used as the stabilizer. The antioxidant protects the physical properties of the polymer resin at high temperatures by preventing air oxidation. As the antioxidant of the present invention, it is preferable to use any one selected from thioester-based and phenol-based materials, or a mixture of two or more selected from them, and a specific example thereof is A / O 1010. In the present invention, the antioxidant is contained in an amount of 0.2 to 10 parts by weight based on 100 parts by weight of the base resin. When the antioxidant is contained in an amount of less than 0.2 part by weight, the antioxidant effect is insignificant, and even if the antioxidant is added in an amount exceeding 10 parts by weight, the antioxidant effect is not further increased.
In addition, the flame-retardant insulating material according to the present invention may further contain various functional additives conventionally used in the insulating resin composition within a range not hindering the effect of the present invention. Such additives include an ultraviolet ray inhibitor, an anti-blocking agent, an antistatic agent, a wax, a coupling agent, a pigment, etc. Although not illustrated, various kinds of materials can be selected and used as needed.
The present invention also provides an insulated electric wire comprising the insulating layer made of the flame-retardant insulating material. When the insulating layer is made of the flame-retardant insulating material of the present invention, the insulating layer can be produced without the need of cross-linking due to the high temperature stability of the polyphenylene oxide, and a high level of flame retardancy, There is an advantageous effect. Using conventional methods, the flame-retardant insulating material of the present invention can be made of an insulating layer surrounding a metal conductor, which can be kneaded and pressed, and its specific method is not described in detail because it is well known in the art.
