状況を観察した結果を次表に示す。
The present invention relates to a method for producing a crosslinked molded body suitable as an insulator for electric wires and cables. Electric wires and cables using crosslinked polyethylene or ethylene propylene rubber as insulators have been widely used. However, it is known that electrical deterioration progresses when electricity is applied in a flooded state.
Although this deterioration generally progresses more slowly in crosslinked polyethylene than in ethylene propylene rubber, it has been recognized that a unique form of deterioration called water tree occurs in crosslinked polyethylene. It is thought that electric wires and cables will continue to be used in flooded environments, such as buried underground, and there is an urgent need to develop electric wires and cables that can suppress the growth of water trees. The present invention has been made based on the above, and an object of the present invention is to provide a method for producing a crosslinked molded product having an extremely significant water tree suppression effect. That is, the present invention uses ethylene and carbon atoms of 4 to 10.
of α-olefin and polyene, and the molar ratio of ethylene and α-olefin is 75/25 to 95/5.
A silane-grafted ethylene/α-olefin/polyene copolymer obtained by reacting an ethylene/α-olefin/polyene copolymer with a silane compound and a radical generator is mixed with a silanol condensation catalyst and subjected to a heating reaction. It is characterized by extrusion molding and crosslinking the obtained extruded product in the presence of moisture. In the present invention, the ethylene/α-olefin/polyene copolymer can be used as a catalyst, for example.
(OR) o X 3 −n (where R is an aliphatic hydrocarbon group,
X is a halogen, a vanadium compound represented by 0<n≦3) and a vanadium compound with an average composition of R′ n AlX′ 3 −m (however,
R' is a hydrocarbon group, X' is a halogen, 1≦m≦1.5)
Using an organoaluminum compound shown by
While maintaining Al/V (atomic ratio) at 5 or more, ethylene, α-olefin having 4 to 10 carbon atoms, and polyene are continuously polymerized at a temperature of 40 to 100°C in a hydrocarbon solvent in the presence of a large amount of hydrogen. That's what you get. Examples of the polyene used here include non-conjugated dienes such as 1,4 hexadiene and 5-ethylidene-2-norbornene. Ethylene and α-olefin have a molar ratio of 75/25
It is desirable to polymerize at a ratio of ~95/5, and 75/5.
If it is less than 25, the mechanical strength will be small, and if it is more than 95/5, the water tree suppression function will be reduced. The molecular weight of the ethylene/α-olefin/polyene copolymer is not particularly limited, but from the viewpoint of extrusion moldability, one having a density of 0.88 to 0.91 g/cm 3 and a melt index of 0.1 or more is suitable. Silane compounds are aliphatically unsaturated carbonized compounds that contain hydrolyzable organic groups, such as alkoxy groups such as methoxy, ethoxy, or butoxy groups, and are reactive with free radical sites generated in organic polymers. Compounds having a hydrogen group or a hydrocarbonoxy group are preferred, and typical examples include vinyltrimethoxysilane, vinyltriethoxysilane, and vinyltriacetoxysilane. As a radical generator, dicumyl peroxide, benzoyl peroxide, 2,5-dimethyl-
Examples include organic peroxides such as 2,5-di(tert-butyl-peroxy)hexyne-3, and azo compounds such as azobisisobutyronitrile and dimethylazoisobutyrate. Silane grafted ethylene・α-olefin・
To obtain a polyene copolymer, a silane compound and a radical generator are added to an ethylene α-olefin/polyene copolymer, and the mixture is heated and reacted at a temperature of approximately 200°C using equipment such as an extruder, Banbury mixer, or roll mill. . A crosslinked molded product is obtained by adding and mixing a silanol condensation catalyst to the thus obtained silane-grafted ethylene/α-olefin copolymer, extrusion molding, and bringing the extruded molded product into contact with moisture. Examples of the silanol condensation catalyst include dibutyltin dilaurate, dibutyltin diacetate, and cobalt naphthenate. In the present invention, polymers such as polyethylene, polypropylene, polybutene-1, poly4-methylpentene-1, ethylene vinyl acetate copolymer, ethylene ethyl acrylate copolymer, etc. may be added within a range that does not impair the electrical properties. It is possible, and antioxidants, lubricants, etc. may be added as appropriate. Examples of the present invention will be explained below. Example 1 Molar ratio of ethylene and α-olefin is 85/15
A solution of 2.0 parts by weight of vinyltrimethoxysilane and 0.2 parts by weight of dicumyl peroxide was dispersed in 100 parts by weight of an ethylene/α-olefin/polyene copolymer with a melt index of 1, and a screw extruder was used. The copolymer was extruded at an extrusion temperature of 200°C to form a silane-grafted ethylene/α-olefin/polyene copolymer, which was then pelletized using a pelletizer. Next, 100 parts by weight of the pellets and 1 part by weight of dibutyltin dilaurate were introduced into an extruder,
A 0.5 mm thick polyethylene semiconductive layer is coated on a copper conductor with an outer diameter of 3 mm.Insulator thickness is 2 mm on the outer periphery.
The crosslinked insulated wire was coated by extrusion and immersed in warm water at 80°C for 15 hours to obtain a crosslinked insulated wire. Example 2 Molar ratio of ethylene and α-olefin is 81/19
A crosslinked insulated wire was obtained in the same manner as in Example 1 except that an ethylene/α-olefin/polyene copolymer having a melt index of 3 was used. Comparative Example 100 parts by weight of low density polyethylene with a density of 0.290 and a melt index of 1 and 2.5 parts by weight of dicumyl peroxide were introduced into an extruder.
A 0.5 mm thick polyethylene semiconductive layer is coated on a copper conductor with an outer diameter of 3 mm.Insulator thickness is 2 mm on the outer periphery.
The crosslinked insulated wire was coated by extrusion and heated in high-pressure steam at 200°C to obtain a crosslinked insulated wire. The results of observing the occurrence of water trees in the cross-linked insulated wire thus obtained are shown in the following table.

The insulated wire was immersed in distilled water, and a 3KV, 50Hz AC voltage was applied between the copper conductor and the water at room temperature for 18 months. After the electrification was completed, the insulator was cut into circular slices, boiled and stained with a methylene blue aqueous solution, and the number of water trees generated was observed using an optical microscope. As is clear from the above description, according to the present invention, a crosslinked molded article having an excellent water tree suppression effect can be obtained, and particularly contributes significantly to improving the reliability of crosslinked electric wires and cables.
