10 Insulated wire 12 Core part 14 Insulation material

The present invention relates to a composition for producing an insulation for electric wire coating, and an electric wire manufactured by using the same. More particularly, an electric wire avoiding the use of a metal hydroxide such as magnesium hydroxide or aluminum hydroxide whose surface is treated with a predetermined material as a flame retardant. A dosage insulating composition and a wire made using the same.

In manufacturing the insulation material for electric wire coating, in the crosslinking reaction between the metal hydroxide and the unsaturated organic silane-bonded polymer resin, maleic acid or maleic anhydride-bonded resin is used. A technique for solving the whitening phenomenon of water-retardant cross-linked flame retardant materials using hydroxide and improving flame retardancy and extrusion processing characteristics has been introduced through US Patent No. 5,002,996.

However, when used as a flame retardant in a state in which the surface of the metal hydroxide is not treated as in the prior art, a scorch phenomenon may occur during compounding, and thus mechanical properties may be sharply degraded or, in severe cases, the material may be decomposed. In addition, the crosslinking reaction proceeds in a natural state after compounding, and thus the melt index of the compound is increased, thereby causing a problem that the extrusion workability is significantly reduced. On the other hand, there is a process difficulty in forming the temperature conditions required during the extrusion process, and when the screw rotation is increased to increase the extrusion amount, the internal heat is intensified due to the high shear force, resulting in a scorch phenomenon, resulting in the extrusion process. The progress of the process becomes difficult, and the appearance of the molded product produced therefrom is not good, and there is a problem in that the quality of the electric wire and the mechanical properties of the insulating material cannot be sufficiently secured.

In addition, an insulated wire having a structure in which the conductor is directly covered with a flame retardant insulator requires an electrical property, namely an insulation resistance value, due to immersion at a high temperature according to a voltage class. Even in the case of the insulating material manufactured by applying the metal hydroxide, there is a problem that the volume resistance of the insulating material as well as the insulation resistance in the wire is low at room temperature.

As described above, the quality and mechanical properties of the insulating material, as well as the electrical properties such as the resistance value is recognized in the various problems that appear deteriorated, and in the related fields, efforts have been made to solve the problems identified in the prior art, Under this technical background, the present invention has been made.

The technical problem to be solved by the present invention based on the above-mentioned conventional problems is to reduce the extrusion workability caused by using the metal hydroxide as a flame retardant, the electrical properties such as the quality and mechanical properties and insulation resistance of the insulating material of the wire is reduced. In order to solve the problem, in order to solve the technical problem, there is an object of the present invention to provide a composition for producing an insulating material for wire coating comprising a surface-treated inorganic flame retardant and a wire manufactured using the same.

The present invention provided for achieving the technical problem to be achieved by the present invention relates to a composition for producing an insulation material for electric wire coating comprising a base resin, a flame retardant, a crosslinking agent and an organosilane reactively bonded to the base resin, in particular a flame retardant As a surface-treated metal hydroxide is used, the present invention relates to an electric wire coated with an insulating material produced using the composition for producing an electric wire coating insulation.

Hereinafter, specific examples will be described in order to help the understanding of the present invention, and in the following case, with reference to the drawings will be described in more detail. However, embodiments according to the present invention can be modified in many different forms, and the scope of the present invention should not be construed as being limited to the embodiments described below. Embodiments of the present invention are provided to more fully explain the present invention to those skilled in the art.

The base resin is any one selected from ethylene vinyl acetate (EVA) copolymer, ethylene ethyl acrylate (EEA) copolymer, ethylene methyl methacrylate (EMMA) copolymer and ethylene butyl acrylate (EBA) ethylene copolymer Alternatively, two or more mixed resins may be used, and vinyl acetate (VA), ethyl acrylate (EA), methyl methacrylate (MMA), and butyl acrylate, which are components other than ethylene contained in the ethylene copolymer. It is preferable that each content of (BA) is 9 to 33 weight%. At this time, the vinyl acetate (VA), ethyl acrylate (EA), methyl methacrylate (MMA), butyl acrylate (BA), except for ethylene contained in the ethylene-based copolymer resin increases the polarity of the flame retardant It is a component calculated | required for the purpose of improving affinity with. Regarding the numerical range for the component content for increasing the intramolecular polarity, if the lower limit is less than the lower limit, it is difficult to secure the flame retardant due to the improper filling of the flame retardant, and if the upper limit is exceeded, the tensile strength and elongation are not preferable. It is not preferable because the mechanical properties related to the flow and abrasion, etc. are lowered, the melt index is out of range, and the dispersibility and extrusion characteristics are lowered.

On the other hand, the base resin, 40 to 95% by weight of the ethylene-based copolymer resin; And 5 to 60 wt% of a polyethylene-based resin or an ethylene alpha olefin copolymer resin. The composite resin blended may be used. At this time, in relation to the numerical range of the content of the ethylene copolymer resin constituting the basic resin, it is not preferable to lower the tensile strength and flame retardancy if it is less than the lower limit, and if it exceeds the upper limit, it is preferable to lower the electrical insulation. Can not do it. On the other hand, the reason for limiting the value for the content of the polyethylene-based resin or the ethylene alpha olefin copolymer resin constituting the base resin is the opposite of the reason for limiting the value for the content of the ethylene copolymer resin constituting the base resin It can be understood that.

On the other hand, the ethylene copolymer resin contained in the base resin is an ethylene vinyl acetate (EVA) copolymer, an ethylene ethyl acrylate (EEA) copolymer, an ethylene methyl methacrylate (EMMA) copolymer combined with an unsaturated organic silane and Any one or two or more mixed resins selected from the ethylene butyl acrylate (EBA) copolymer may be used, and vinyl acetate (VA) and ethyl acrylate (EA), which are components other than ethylene contained in the ethylene copolymer. It is preferable that the content of each of methyl methacrylate (MMA) and butyl acrylate (BA) is 9 to 33% by weight. The numerical limitation in this regard is the same as described above. On the other hand, the polyethylene resin contained in the base resin is preferably any one or two or more materials selected from low density polyethylene (LDPE), linear low density polyethylene (LLDPE) and high density polyethylene (HDPE). And, the alpha olefin copolymer included in the base resin is butene-1, pentene-1, hexene-1, heptene-1, octene-1, 4-methylpentene-1, 4-methylhexene-1, 4, It is preferable if it is any one or two or more substances selected from 4-dimethylpentene-1, nonene-1, decene-1, undecene-1 and dodecene-1.

The flame retardant is included in an amount of 50 to 250 parts by weight based on 100 parts by weight of the base resin, and is a metal hydroxide surface-treated with one or two or more materials selected from vinylsilane, stearic acid, oleic acid, amino polysiloxane and polymer resin. Preferably magnesium hydroxide or aluminum hydroxide can be used. In this case, in relation to the numerical limitation on the flame retardant content, if the lower limit is not reached, the purpose of securing the flame retardant can not be achieved, and if the upper limit is exceeded, the amount of the flame retardant does not increase in proportion to the added amount. On the contrary, the excessive amount is not only deteriorate the physical properties of the product, but also undesirable in terms of economics. As described above, the surface treatment of the inorganic flame retardant may inhibit the crosslinking reaction between the hydroxyl group (-OH) on the surface of the inorganic flame retardant and the alkoxy groups of the unsaturated organic silane during compounding, storage or extrusion. . As a result, the change of physical properties due to the crosslinking reaction does not occur during compound storage, thereby facilitating extrusion and forming an excellent extrusion appearance, thereby securing the quality of the wire and the mechanical properties of the insulating material.

On the other hand, the composition for preparing the insulation for the electric wire coating, it is more preferable that a silicon-based or zinc-based flame retardant aid is further included as content of 2 to 30 parts by weight based on 100 parts by weight of the base resin. At this time, the flame retardant aid, it is preferable to use a surface-treated as one or two or more selected from vinylsilane, stearic acid, oleic acid, amino polysiloxane and polymer resin. As such, the use of surface-treated flame retardant aids can further enhance the chemical and physical effects obtainable by using surface-treated inorganic flame retardants as described above. At this time, in relation to the numerical range of the content of the flame retardant aid, if the lower limit value is less than the synergistic effect with the flame retardant does not have the added meaning is not preferable, and if the upper limit is exceeded, the amount is increased in proportion to the added flame retardancy improvement It is not desirable to reduce the physical properties of the product due to the excessive amount present, but not in terms of economics.

The crosslinking agent is a peroxide-based material contained in an amount of 0.01 to 0.5 parts by weight based on 100 parts by weight of the base resin, and preferably di- (2,4-dichlorobenzoyl) -peroxide [Di- (2,4- dichlorobenzoyl) -peroxide], Dibenzoyl peroxide, tert-Butyl peroxybenzoate, 1,1-di- (tertiary-butylperoxy) -3, 3,5-trimethylcyclohexane [1,1-di- (tert-butylperoxy) -3,3,5-Trimethylcyclohexane], Dicumyl peroxide, Tert-Butylcumylperoxide ], Di- (2-tertary-butyl-peroxyisopropyl) -benzene [di- (2-tert-buty-peroxyisopropyl) -benzene], 2,5--dimethyl-2,5-di- ( Tert-butylperoxy) -hexane [2,5-Dimethyl-2,5-di- (tert-butylperoxy) -hexane], di-tert-butylperoxide and 2 , 5-dimethyl-2,5-di (tertiary-butylperoxide) hex-3 [2,5-dimethyl-2,5-di (tert-butylperoxy) hexyme-3] may be used one or more materials selected from the group consisting of materials. At this time, in relation to the numerical range of the content of the crosslinking agent, if the lower limit is not reached, sufficient crosslinking is not achieved, thereby making it difficult to obtain a desired physical property. If the upper limit is exceeded, a by-product of the crosslinking reaction is excessive, resulting in a volume. By lowering the resistance, a problem of lowering the insulation properties occurs, which is undesirable.

The organosilane is an olefinically unsaturated organosilane which is contained in an amount of 0.5 to 10 parts by weight based on 100 parts by weight of the base resin and reacts to the ethylene copolymer resin which is the base resin by peroxide as a crosslinking initiator. The olefinically unsaturated organic silane is represented by the formula R-SiR ' _a Y _3-a . R in the formula represents an ethylenically unsaturated hydrocarbon group or a hydrocarboxyl group, R 'in the formula represents an aliphatic saturated hydrocarbon group, Y in the formula represents an organic group that hydrolyzes, and The indicated subscript a is preferred if the substance satisfies a real number greater than zero and less than or equal to two. In this case, in relation to the numerical range of the content of the organosilane, it is not preferable to improve the tensile strength and oil resistance and hot / set characteristics if it is less than the lower limit, and if it exceeds the upper limit, the elongation and flame retardancy are exceeded. It is not preferable because of this deterioration.

On the other hand, when the antioxidant, lubricant and processing aids are further added to the composition for producing an insulation for wire coating according to the present invention can achieve a more preferable technical effect.

The antioxidant is preferably used in a single material or a mixture of two or more selected from amine, dialkyl ester, thioester and phenolic materials in an amount of 0.5 to 5 parts by weight based on 100 parts by weight of the base resin. . Regarding the numerical range for the antioxidant content, if it falls below the lower limit, the antioxidant function is not sufficiently expressed, and heat resistance becomes poor, and if the upper limit is exceeded, the antioxidant effect proportional to the added amount is not expressed. On the contrary, it is not preferable because of the problem that the addition lowers the economic feasibility.

The lubricant may be a material such as polyolefin wax, paraffin wax, paraffin oil, stearic acid, metal soap, organosilicon, fatty acid ester, fatty acid amide, fatty alcohol, fatty acid, etc., from 0.5 to 100 parts by weight of the base resin It is preferable to use in the content of 5 parts by weight. At this time, with respect to the numerical range for the lubricant content, if the lower limit is lower than the expected lower processability improvement due to the viscosity decrease of the material is not preferable, if the upper limit exceeds the flame retardancy, low smokeability and tensile strength is preferable. I can't.

The processing aid, polyolefin wax, paraffin wax, paraffin oil, stearic acid, metal soap, organosilicon, fatty acid ester, fatty acid amide, fatty alcohol, fatty acid and the like can be used, optionally in connection with the lubricant selected Can be used in combination. The processing aid is preferably used in an amount of 0.5 to 5 parts by weight based on 100 parts by weight of the basic resin. Regarding the numerical range for the processing aid content, if it is less than the lower limit, the flowability is poor due to the adhesion between the material and the metal surface during extrusion, and the improvement of workability due to the viscosity decrease in the material cannot be expected. It is not preferable to exceed the flame retardancy, low smokeability and tensile strength.

As can be seen through Table 3, in the case of Examples 1 to 6 according to the present invention, as a result of measuring the room temperature volume resistance of the material, it showed a value of 1 × 10 ¹⁵ Ω · cm or more, which is a requirement of the present invention. . In addition to satisfying the flame retardancy of IEC 332-3 Cat.C in the wire state, the basic oxygen required for the material showed more than 30%. Basically required mechanical properties at room temperature, physical properties after heating and hot set were also satisfactory. In addition, in Table 3, as a result of evaluating low smoke characteristics that were not applied in the conventional evaluation, the smoke density characteristics of 80% or more according to IEC 601034 and the smoke index characteristics of 10 or less according to NES 711 were satisfied. As a result of measuring the degree of emission of toxic gas that affects the environment, human body and equipment by the recently emerging combustion, the toxicity index below 1 according to NES 713 and the halogen content below 0.5% according to IEC 60754-1 It was found to be excellent. In the embodiments according to the present invention, the whitening phenomenon of the wire is significantly reduced by using the surface-treated metal hydroxide and inorganic additives, the extrusion processability of the material is very good, the surface appearance is not only smooth, but also the scorch phenomenon during extrusion processing This did not happen.

Unlike Examples (1 to 6) described above, in Comparative Example 1 is a low-density polyethylene resin in which the unsaturated organic silane is bonded to the ethylene-vinyl acetate copolymer resin having a content of 28% vinyl acetate bonded to the unsaturated organic silane Blend was used as base resin, untreated surface treated magnesium hydroxide and flame retardant aid were added. Room temperature was applied to ethylene vinyl acetate having 28% by weight of vinyl acetate and untreated metal hydroxide on low density polyethylene. The elongation was lowered and the volume resistivity of the material was low. In addition, the low-density polyethylene applied to improve the volume resistivity not only did not meet the oxygen index requirement but also caused scorch due to the reaction of hydroxy groups on the surface of the silane and the metal hydroxide during compounding and extrusion.

On the other hand, in Comparative Example 2, as a result of adding a red flame retardant to the same composite resin and flame retardant structure as that of Comparative Example 1 to improve flame retardancy, the wire applied with the insulating material of Comparative Example 2 had a smoke density, a smoke index and a toxicity index. I was not satisfied. Therefore, the ethylene vinyl acetate copolymer having a 28% content of vinyl acetate in which unsaturated organic silane is bonded, as shown in the present invention, can not exhibit the crosslinked insulated wire property having low smoke-low toxicity property and cannot be confirmed in Comparative Example 3 Compound mill extrusion processability was improved when magnesium hydroxide surface-treated with stearic acid was used as the resin. However, as the room temperature elongation rate increased, the elongation residual rate decreased after heating. The need to control the amount of peroxide has emerged, and the room temperature resistivity and the insulation resistance of wires have been significantly reduced. Finally, in the case of Comparative Example 4, aluminum hydroxide without surface treatment was used for the ethylene vinyl acetate copolymer resin having a content of 28% vinyl acetate bonded with unsaturated organic silane. In addition, it is difficult to satisfy the oxygen index alone with aluminum hydroxide alone, so that the addition of red phosphorus is performed to improve the flame retardancy. Basically, low-density polyethylene with excellent electrical properties was used to satisfy the characteristics of volume resistance and insulation resistance, but the mechanical properties were deteriorated due to excessive addition of aluminum hydroxide and flame retardant for flame retardancy, and the smoke index and toxicity index were high. In addition, due to the low surface temperature of the non-surfaced aluminum hydroxide, scorch and decomposition due to crosslinking of the silane occurred during compounding and extrusion.

As described above, as can be seen from the characteristics evaluation results of Comparative Examples 1 to 4, when the composite resin is properly mixed in order to improve the electrical properties and reduce the whitening phenomenon, the extrusion process characteristics and the flame retardancy and low smoke characteristics are in conflict with each other. Phenomenon occurs. It was clearly technically clear that it is difficult to fundamentally improve the extrudability and electrical properties if the surface of the inorganic additive is not treated with a specific organic material.

Optimal embodiments of the present invention described above have been disclosed. Although specific terms have been used herein, they are used only for the purpose of describing the present invention in detail to those skilled in the art and are not intended to limit the scope of the present invention as defined in the claims or the claims.

By using the composition for producing an insulation for wire coating according to the present invention, the extrusion processability is improved during the production of the wire, the appearance of the manufactured product is excellent, it is possible to supply an insulated wire with excellent mechanical properties as well as electrical insulation, especially in the event of a fire And it has the advantage to provide a low smoke low toxicity insulating wire having a flame retardancy that can minimize the damage to expensive equipment.
