【表】DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a protective coating layer for electric wires and cables. Generally, electric wires and cables have an insulating layer of plastic or rubber on the conductor, and a protective coating layer (sheath layer) for protection from the external environment. This sheath layer is required to have various properties such as environmental stress cracking resistance, weather resistance, cold resistance, abrasion resistance, oil resistance, and chemical resistance. Conventionally, high-pressure polyethylene and ethylene/vinyl acetate copolymer have been used as materials for forming the sheath layer, but high-pressure polyethylene still has insufficient environmental stress cracking resistance, and ethylene/vinyl acetate copolymer has poor cold resistance. The drawbacks were poor wear resistance and wear resistance. As a result of intensive research to solve the above drawbacks, the present inventors discovered that the above problems could be solved all at once by using a special polyolefin manufactured by a specific method, and completed the present invention. This is what led to this. That is, the present invention provides ethylene and an α-olefin having 3 to 12 carbon atoms in a gas phase substantially free from a solvent in the presence of a catalyst consisting of a solid substance containing magnesium, titanium, and/or vanadium, and an organic aluminum. Ethylene α- having a density of 0.890 to 0.945 and a melt index of 0.01 to 5 obtained by copolymerizing with

In addition, by bringing the above catalyst system into contact with α-olefin and then using it in a gas phase polymerization reaction, the polymerization activity can be greatly improved and operation can be made more stable than when untreated. . Various α-olefins can be used as the α-olefin used at this time, but α-olefins having 3 to 12 carbon atoms are preferable, and α-olefins having 3 to 8 carbon atoms are more preferable.
α-olefin is preferred. Examples of these α-olefins include propylene, butene-1, pentene-1, 4-methylpentene-1,
Examples include heptene-1, hexene-1, octene-1, decene-1, dodecene-1, and mixtures thereof. The temperature and time during contact between the catalyst system and the α-olefin can be selected within a wide range, for example 0 to 200°C, preferably 0 to 200°C.
Contact treatment can be carried out at 110°C for 1 minute to 24 hours. The amount of α-olefin to be brought into contact can be selected within a wide range, but it is usually 1 g to 1 g per 1 g of the solid substance.

It is desirable to react 500 g of alpha-olefin. At this time, the pressure at the time of contact can be arbitrarily selected, but it is usually desirable to bring them into contact under a pressure of -1 Kg/cm 2 ·G (meaning under reduced pressure of 1 atmosphere) to 100 Kg/cm 2 ·G. During the α-olefin treatment, the entire amount of the organoaluminum compound used may be combined with the solid substance and then brought into contact with the α-olefin, or a part of the organoaluminum compound used may be combined with the solid substance.

The polymerization reaction may be carried out by contacting with olefin and adding the remaining organoaluminum compound separately during gas phase polymerization. Further, when the catalyst system and the α-olefin are brought into contact, there is no problem even if hydrogen gas coexists, and there is no problem even if other inert gases such as nitrogen, argon, helium, etc. coexist. The special polyolefin in the present invention is produced by copolymerizing ethylene and α-olefin in the gas phase in the presence of a solid material containing magnesium and a titanium compound and/or a vanadium compound and a catalyst consisting of an organoaluminum compound. The essence is to use a copolymer having a predetermined melt index and density obtained by the above method, and the α-olefin used in the copolymerization reaction is
Those having 3 to 12 carbon atoms are used. Specifically, propylene, butene-1, pentene-1, 4-methylpentene-1, heptene-1, hexene-1,
Octene-1, decene-1, dodecene-1, etc. can be mentioned. The polymerization reaction is carried out in a gas phase substantially free of solvent. As the reactor used, known reactors such as a fluidized bed and a stirring tank can be used. The polymerization reaction temperature is usually 0 to 110°C, preferably
The temperature is 20 to 80°C, and the pressure is normal pressure to 70 kg/cm 2 ·G, preferably 2 to 60 kg/cm 2 ·G. Although the molecular weight can be controlled by adjusting the polymerization temperature, the molar ratio of the catalyst, the amount of comonomer, etc., it is effectively carried out by adding hydrogen to the polymerization system. Of course, a two-stage or more multi-stage polymerization reaction may be carried out using different polymerization conditions such as hydrogen concentration, comonomer concentration, and polymerization temperature. As described above, in the presence of a catalyst consisting of a solid material containing magnesium, titanium and/or vanadium, and an organoaluminium, the present invention is capable of combining ethylene and carbon atoms having a carbon number of 3 to 12 in a gas phase substantially free of a solvent. By using an ethylene/α-olefin copolymer obtained by copolymerizing α-olefin with a density of 0.890 to 0.945 and a melt index of 0.01 to 5 as the sheath layer forming material, the properties of the sheath layer can be significantly improved. The improvement was completely unexpected. In the present invention, known auxiliary agents such as pigments, fillers, dispersants, antioxidants, and ultraviolet absorbers may be appropriately blended with the special polyolefin of the present invention, if necessary. In addition, in the present invention, it is possible to appropriately blend polyolefins obtained by other methods with the special polyolefins obtained by the specific method of the present invention.
There is no problem as long as the properties of the special polyolefin of the present invention are not impaired. Examples of these other polyolefins include high-pressure polyethylene, ethylene/vinyl acetate copolymers, and polyolefins obtained by medium- or low-pressure solution polymerization or slurry polymerization. The blending ratio of these is preferably 100 parts by weight or less based on 100 parts by weight of the special polyolefin of the present invention. EXAMPLES The present invention will be specifically explained below using Examples, but the present invention is not limited thereto. Example 1 1000 g of anhydrous magnesium chloride, 50 g of 1,2-dichloroethane and 170 g of titanium tetrachloride were ball milled at room temperature in a nitrogen atmosphere for 16 hours to support the titanium compound on the carrier. 1g of this solid substance
Contains 40mg of titanium per serving. A stainless steel autoclave was used as the apparatus for gas phase polymerization, and a loop was formed with a blower, a flow control valve, and a dry cyclone for separating the produced polymer, and the temperature of the autoclave was controlled by flowing hot water through the jacket. The polymerization temperature was set at 70°C, and the above solid substances were supplied to the autoclave at a rate of 250 mg/hr and triethylaluminum at a rate of 50 m-mol/hr. ) respectively
Copolymerization of ethylene and propylene was carried out while adjusting the hydrogen pressure to be 10% of the total pressure. The produced ethylene-propylene copolymer had a melt index of 0.2 and a density of 0.925. 100 parts by weight of the above ethylene-propylene copolymer, 2.5 parts by weight of carbon black and 4,4'-
0.2 parts by weight of thiobis(6-t-butyl-4-hydroxybenzyl) was added and mixed on a roll set at 160°C. The melt index of the mixture was 0.2 and the density was 0.935. Next, the mixture was made into a sheet with a thickness of 3.0±0.2m/m and tested according to ASTM D-1693.
When the environmental stress cracking resistance (ESCR) was measured using a method, there was no cracking at all even after more than 6,000 hours. Furthermore, when the mixture was tested for low temperature brittleness at a temperature of -75°C in accordance with JIS K6760 using a sheet having a thickness of 2.0±0.2 m/m, no cracks were found. Further, when the mixture was made into a sheet with a thickness of 3.0±0.1 m/m and its abrasion properties were examined using a taper type abrasion tester, the abrasion was extremely small. Example 2 In Example 1, the composition of the gas supplied to the autoclave was changed to 96 mol% ethylene and hexene.
Copolymerization of ethylene and hexene-1 was carried out in the same manner as in Example 1, except that the polymerization concentration was 14 mol %, hydrogen was 18% of the total pressure, and the polymerization was carried out at 85°C. The produced ethylene/hexene-1 copolymer had a melt index of 1.0 and a density of 0.925. To 100 parts by weight of this ethylene-hexene-1 copolymer, 2.5 parts by weight of carbon black and 4,
0.2 parts by weight of 4'-thiobis(6-t-butyl-4-hydroxybenzyl) was added and mixed, resulting in a mixture with a melt index of 1.0 and a density of 0.935, which was subjected to ESCR and low temperature in the same manner as Example 1. When brittleness and abrasion resistance were examined, all points were good. Example 3 In Example 1, the composition of the gas supplied to the autoclave was changed to 88 mol% ethylene and 1 butene-1.
Assuming 12 mol% and hydrogen as 14% of the total pressure,
Copolymerization of ethylene and butene-1 was carried out in the same manner as in Example 1 except that the polymerization was carried out at 80°C. The resulting ethylene-butene-1 copolymer had a melt index of 1.0 and a density of 0.920. To 100 parts by weight of this ethylene-butene-1 copolymer, 2.5 parts by weight of carbon black and 0.2 parts by weight of 4,4'-thiobis(6-t-butyl-4-hydroxybenzyl) are added and mixed. A mixture having a melt index of 1.0 and a density of 0.930 was examined for ESCR, low temperature brittleness and wear resistance in the same manner as in Example 1, and was found to be good in all respects. Comparative Example 1 Same as Example 1 except that low-density polyethylene with a melt index of 0.15 and a density of 0.920 manufactured by a high-pressure method was used instead of the ethylene-propylene copolymer used in Example 1. When the ESCR, low-temperature brittleness and wear resistance were examined by the method, the ESCR was very poor and the wear resistance was also unsatisfactory. Comparative Example 2 Instead of the ethylene/propylene copolymer used in Example 1, an ethylene/vinyl acetate copolymer (vinyl acetate content: 3 mol%) with a melt index of 0.15 and a density of 0.922 produced by a high-pressure method was used. The ESCR, low-temperature brittleness and wear resistance were examined in the same manner as in Example 1, except that the results were unsatisfactory in all respects. 【table】
