Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an olefin resin composition, and more particularly to a non-halogen flame-retardant polyolefin resin composition capable of improving mechanical strength (tensile properties) and insulation resistance.

[0002]

2. Description of the Related Art As a thermoplastic resin composition, a polyvinyl chloride resin composition has been used more frequently than before because of its relatively high withstand voltage and insulation resistance, low production cost, and excellent flame retardancy by itself. ing. However, in a conventional thermoplastic resin composition using such a polyvinyl chloride resin composition, for example, when electric wires and cables are burned for incineration and disposal, corrosion from the polyvinyl chloride resin composition occurs. There is a problem that hydrogen chloride gas having a property is generated. In recent years, attempts have been made to use an olefin-based resin composition such as polyethylene as an insulator that does not use a halide, as an insulator for electric wires and cables at a location that emits high temperature, such as a wire harness of an automobile. Since this olefin resin composition does not have flame retardancy by itself, it is made to have flame retardancy by mixing a metal hydroxide such as magnesium hydroxide.

[0003]

However, when this metal hydrate such as magnesium hydroxide is mixed with an olefin resin, it is a foreign substance when viewed from the olefin resin.
Even from the composition structure of the olefin-based resin composition, it causes a strong bond to be broken. That is, when a metal hydroxide such as magnesium hydroxide is blended, the structure of the olefin resin composition becomes less rigid and brittle. For this reason, when a large amount of metal hydroxide such as magnesium hydroxide is mixed, there is a problem that mechanical properties (tensile properties) are deteriorated. The amount of hydroxide must be reduced.

[0004] However, an insulator mainly composed of such an olefin-based resin composition needs to be mixed with a large amount of a metal hydroxide such as magnesium hydroxide in order to obtain high flame retardancy. However, if a large amount of a metal hydroxide such as magnesium hydroxide is mixed, the abrasion resistance to mechanical shock is reduced and the insulation (volume resistivity) is reduced. In order to suppress a decrease in the property (volume resistivity), the amount of metal hydroxide such as magnesium hydroxide to be mixed must be reduced. If the amount of the metal hydroxide such as magnesium hydroxide is reduced, it is not possible to obtain the desired advanced flame retardant properties (for example, the same flame retardancy as that of the polyvinyl chloride resin composition). Would.

[0005] However, depending on the purpose of use, such as for covering insulators of electric wires and cables, it is required to have not only flame retardancy but also abrasion resistance and insulation. Therefore, when a composition containing an olefin-based resin as a main component is used for an insulator, conventionally, a small amount of a metal hydroxide such as magnesium hydroxide is blended with the olefin-based resin to reduce the flame retardancy of a phosphorus-based flame retardant. There has been proposed one that attempts to obtain flame retardancy by mixing an agent. However, the effect of the flame retardant auxiliary is not remarkable in order to improve the flame retardancy, and there is a problem that high flame retardant properties cannot be obtained.

SUMMARY OF THE INVENTION It is an object of the present invention to improve the tensile properties, improve the volume resistivity (insulating property), and reduce the generation of hydrogen halide during combustion by using an olefin resin containing no halide as a main component. An object of the present invention is to provide a flame retardancy equal to or higher than that of a conventional polyvinyl chloride resin composition.

[0007]

In order to achieve the above object, a halogen-free flame-retardant polyolefin resin composition according to claim 1 is prepared by adding a silane coupling agent to an olefin resin containing a metal hydroxide. It is constituted by blending potassium titanate subjected to surface treatment. Potassium titanate is a crystal (whisker) that has grown into a needle shape, the surface of which is treated with a silane coupling agent. The surface treatment of potassium titanate with this silane coupling agent has good compatibility and coatability with the olefin resin on the surface of potassium titanate in order to obtain compatibility and coatability with the olefin resin with potassium titanate. The silane coupling agent is chemically or physically bonded without deteriorating the physical properties of potassium titanate. According to the invention as set forth in claim 1, the flame retardancy based on the composition of a metal hydroxide such as magnesium hydroxide or the like containing an olefin-based resin as a main component, containing no halide, and having the above configuration. And by adding potassium titanate surface-treated with a silane coupling agent, the tensile properties can be improved and the volume resistivity (insulating property) can be improved.

In order to achieve the above object, a halogen-free flame-retardant polyolefin resin composition according to claim 2 is provided.
It is formed by mixing a metal hydroxide and potassium titanate which has been subjected to a surface treatment with a silane coupling agent to an olefin-based resin, followed by crosslinking. In order to achieve the above object, the non-halogen flame-retardant polyolefin-based resin composition according to claim 3 performs the crosslinking by any of chemical crosslinking using a crosslinking agent, silane crosslinking, and electron beam irradiation crosslinking. Things.

Chemical cross-linking by a cross-linking agent involves cross-linking by adding a cross-linking agent such as dicumyl peroxide (DCP) and heating. When a base resin containing the cross-linking agent is heated, first heating is performed. The crosslinking agent decomposes to form free radicals. The free radicals react with the polymer to activate the polymer and produce polymer free radicals, which combine to form a polymer crosslink. Water cross-linking with vinyl silane involves adding a silane compound (coupling agent) such as dicumyl peroxide (DCP) or vinyl trimethoxy silane (VTMOS) as a free radical generator (cross-linking agent) to an olefin resin as a polymer, and dibutyl. It is carried out by mixing and heating a silanol condensation catalyst (siloxane condensation catalyst) such as tin dilaurate. That is, a polymer (olefin resin), a crosslinking agent (dicumyl peroxide), a silane compound (vinyltrimethoxysilane), and a silanol condensation catalyst (dibutyltin dilaurate) are blended, and when heat is externally applied, the crosslinking agent is decomposed. To form free radicals. The free radicals react with the polymer to activate the polymer to produce polymer free radicals, and the free radicals react with the silane compound (vinyltrimethoxysilane) to form a grafter. Then, a tin-based catalyst (dibutyltin dilaurate) acts on the graftmer, and due to the presence of water, the vinyl of vinyltrimethoxysilane as the silane coupling agent is removed and bonded to the free radical. That is, a chain is formed in a state in which Si (silane) is contained in a polymer (olefin-based resin) molecule, and a similar phenomenon occurs in another polymer (olefin-based resin) molecule, whereby two polymers (olefin-based resin) are formed. 2.) A cross-linking reaction (silane cross-linking) is carried out in a form in which oxygen (O) is in the middle with Si (silane) in the middle, and two polymer (olefin-based resin) molecules are connected to form a cross-linked state. I have.

In electron beam irradiation crosslinking, an olefin resin as a polymer is irradiated with an electron beam to activate the polymer and release hydrogen, thereby generating polymer free radicals. Form polymer crosslinks. With this configuration, according to the second aspect of the present invention, it is difficult to disperse the metal hydroxide compounded in the olefin-based resin composition into chains formed in a lattice by crosslinking. The combustion effect can be improved. In addition, according to the third aspect of the present invention having such a configuration, the crosslinking is performed by using any of chemical crosslinking by a crosslinking agent, silane crosslinking, and electron beam irradiation crosslinking. Can be crosslinked.

[0011] In order to achieve the above object, the halogen-free flame-retardant polyolefin resin composition according to claim 4 comprises:
In the case of chemical crosslinking, it is constituted by blending a silane coupling agent. Coupling agents are chemicals that can react with both the reinforcement and the resin matrix of the composite material to form or promote a strong bond at the interface. That is, the coupling agent bridges between the molecules of the olefin-based resin. Examples of the silane coupling agent include vinyltrimethoxysilane, vinyltriethoxysilane, vinyltributoxysilane, normal hexyltrimethoxysilane, and the like. Various silane coupling agents such as vinyltrimethoxysilane, vinyltriethoxysilane, vinyltributoxysilane, normal hexyltrimethoxysilane, etc.
Vinyltrimethoxysilane) alone,
More than one kind (for example, vinyltrimethoxysilane and vinyltriethoxysilane) can be blended. According to the invention as set forth in the fourth aspect of the present invention, the olefin resin is a main component, does not contain a halide, promotes cross-linking between molecules of the olefin resin, and forms a metal such as magnesium hydroxide. Hydroxide is dispersed in a lattice-like chain by cross-linking to secure the standard flame retardancy, and the tensile properties are improved by blending potassium titanate surface-treated with a silane coupling agent. At the same time, the volume resistivity (insulating property) can be improved.

[0012] In order to achieve the above object, the halogen-free flame-retardant polyolefin resin composition according to claim 5 comprises:
The crosslinking agent used for chemical crosslinking is composed of an organic peroxide or an azo compound. This cross-linking agent is used to start bridging between molecules of the olefin-based resin with a coupling agent. Organic peroxide is hydrogen peroxide HO
_A compound obtained by replacing the hydrogen atom of 2H with an organic group such as an alkyl group or an acyl group. Things. Examples of the organic peroxide include dicumyl peroxide (a medium-temperature crosslinking agent for polyolefin), benzoyl peroxide (a crystal obtained by reacting benzoyl chloride with hydrogen peroxide and alkali or sodium peroxide), and the like. An azo compound is an organic compound in which an azo group is bonded to a carbon atom. With this configuration, according to the invention described in claim 5,
It can spontaneously initiate crosslinking of the olefin resin,
Crosslinks can be formed early.

[0013] In order to achieve the above object, the halogen-free flame-retardant polyolefin resin composition according to claim 6 comprises:
In the case of chemical crosslinking, a siloxane condensation catalyst is blended. The catalyst is for promoting a crosslinking phenomenon in which a coupling agent is interposed between molecules of the olefin-based resin. Examples of the siloxane condensation catalyst include dibutyltin dilaurate, dibutyltin diacetate, and dibutyltin dioctaate. With this configuration, according to the invention described in claim 6, a crosslinking phenomenon in which a coupling agent is interposed between molecules of the olefin-based resin can be promoted.

[0014] In order to achieve the above object, the halogen-free flame-retardant polyolefin resin composition according to claim 7 comprises:
It is composed of 100 parts by weight of a base resin obtained by mixing a metal hydroxide with an olefin resin, and 1 to 8 parts by weight of potassium titanate surface-treated with a silane coupling agent. The base resin is formed by mixing a metal hydroxide with an olefin resin, and 100 parts by weight of the base resin is mixed with 1 to 8 parts by weight of potassium titanate surface-treated with a silane coupling agent. It is configured. The amount of the potassium titanate is adjusted to the base resin 10
The reason why 1 to 8 parts by weight is added to 0 part by weight is that, unless potassium titanate is added to the base resin in an amount of 1 part by weight or more, a predetermined tensile strength and a predetermined volume resistivity cannot be obtained. If the amount exceeds 8 parts by weight, the effect of increasing the amount cannot be obtained. With this configuration, according to the invention described in claim 7, the tensile properties can be improved and the volume resistivity can be improved.

[0015] In order to achieve the above object, a halogen-free flame-retardant polyolefin resin composition according to claim 8 comprises:
The base resin is formed by mixing an olefin resin and a metal hydroxide at a weight ratio of 20:80 to 80:20. The mixing ratio of the olefin-based resin as the base resin to the metal hydroxide is 20:80 to 80:20 by weight. As described above, the weight ratio of the metal hydroxide to the olefin resin is from 80% by weight to 20% by weight.
The reason for this is that when the content of the metal hydroxide exceeds 80% by weight, flame retardancy is improved, but the mechanical strength cannot be maintained at a predetermined level. If the amount is less than 20% by weight, it is not possible to obtain a predetermined flame retardancy (for example, the flame can be extinguished within 30 seconds in a 45 ° inclined combustion test). According to this configuration, the tensile strength can be improved, and the volume resistivity can be improved.

[0016] In order to achieve the above object, the halogen-free flame-retardant polyolefin resin composition according to claim 9 comprises:
An olefin resin is used as a linear low-density polyethylene (LL)
DPE), very low density polyethylene (VLDPE), ethylene-α olefin copolymer, ethylene-vinyl acetate copolymer (EVA), ethylene-acrylic acid copolymer, ethylene-methacrylic acid copolymer, ethylene-acrylic acid Ethyl copolymer (EEA), high density polyethylene (HD
PE) or a mixture of two or more of olefin polymers such as polypropylene (PP). With this configuration, according to the ninth aspect, non-halogenation can be achieved.

In order to achieve the above object, a non-halogen flame-retardant polyolefin resin composition according to claim 10 is characterized in that a metal hydroxide is formed of magnesium hydroxide (Mg (O
H) ₂ ), aluminum hydroxide (Al (OH) ₃ ), and calcium hydroxide (Ca (OH) ₂ ). The metal hydroxide is an inorganic flame retardant used for an olefin resin, such as magnesium hydroxide, aluminum hydroxide, or calcium hydroxide. By blending this metal hydroxide with the olefin resin, the olefin resin is less likely to burn, and has the effect of carbonizing the cinder when burning and having shape retention. With this configuration, according to the tenth aspect of the present invention, the standard flame retardancy can be secured without containing a halide.

In order to achieve the above object, the non-halogen flame-retardant polyolefin resin composition according to claim 11, wherein the surface treatment of potassium titanate is performed using a silane coupling agent comprising an amino silane coupling agent or an epoxy silane coupling agent. It is composed of any of silane coupling agents. Potassium titanate is not compatible with the polyolefin resin as it is, and if potassium titanate is blended without any treatment, it becomes rather brittle and the tensile strength decreases, and the desired mechanical strength is obtained. Disappears. Therefore, the surface treatment is performed with a silane coupling agent compatible with the polyolefin resin. This silane coupling agent may be either an amino silane coupling agent or an epoxy silane coupling agent.
The silane coupling agent includes vinyl trimethoxy silane, vinyl triethoxy silane, vinyl tributoxy silane, normal hexyl trimethoxy silane, and the like. There are various silane coupling agents such as vinyltrimethoxysilane, vinyltriethoxysilane, vinyltributoxysilane, and normal hexyltrimethoxysilane. According to the invention as set forth in the eleventh aspect of the invention, potassium titanate having a surface treatment with a silane coupling agent and having compatibility enters between the olefin-based resins to improve the tensile properties and increase the volume. The resistivity (insulating property) can be improved.

In order to achieve the above object, the non-halogen flame-retardant polyolefin resin composition according to the twelfth aspect of the present invention comprises a olefin resin and a metal hydroxide in a weight ratio of 20:
100 parts by weight of a base resin mixed at a ratio of 80 to 80:20, 1 to 8 parts by weight of potassium titanate surface-treated with a silane coupling agent, 0.05 to 20 parts by weight of a silane coupling agent, organic 0.1 to 10 parts by weight of peroxide or azo compound, 0.5 to 1 part of siloxane condensation catalyst
It is constituted by mixing 0 parts by weight. Here, the compounding amount of the silane coupling agent is set to 0.05 to 20 parts by weight with respect to 100 parts by weight of the olefin resin, when the compounding amount of the silane coupling agent is less than 0.05, the olefin resin is added. This is because crosslinking cannot be sufficiently performed, and even if the silane coupling agent is added in an amount exceeding 20 parts by weight, it does not contribute to a crosslinking reaction between molecules of the olefin-based resin. When two or more silane coupling agents are mixed from vinyltrimethoxysilane, vinyltriethoxysilane, vinyltributoxysilane, normal hexyltrimethoxysilane, etc., the total amount of the two or more silane coupling agents is 0.1. It is necessary that the amount be from 0.5 to 20 parts by weight.

The compounding amount of the organic peroxide or azo compound as a crosslinking agent is 0.1 to 10 parts by weight based on 100 parts by weight of the olefinic resin. If the amount is less than 0.1, the crosslinking between the molecules of the olefin-based resin by the coupling agent cannot be started, and the amount of the organic peroxide or the azo compound exceeds 10 parts by weight. Even so, the cross-linking agent in a portion exceeding 10 parts by weight does not contribute to initiating the crosslinking between the molecules of the olefin-based resin by the coupling agent. Further, the compounding amount of the siloxane condensation catalyst is set to 0.5 to 10 parts by weight with respect to 100 parts by weight of the olefin resin. This is because the cross-linking reaction between the molecules of the resin cannot be promoted, and even if the compounding amount of the siloxane condensation catalyst exceeds 10 parts by weight, the cross-linking reaction is not further promoted. According to the invention as set forth in the twelfth aspect of the present invention, potassium titanate containing an olefin resin as a main component, not containing a halide, and subjected to a surface treatment with a silane coupling agent is blended. Crosslinking between the molecules of the olefin resin with a coupling agent, dispersing metal hydroxides such as magnesium hydroxide into chains in a lattice by crosslinking to ensure flame retardancy, and use a silane coupling agent to coat the surface. By blending the treated potassium titanate, the tensile properties can be improved and the volume resistivity (insulating property) can be improved.

In order to achieve the above object, the non-halogen flame-retardant polyolefin resin composition according to the thirteenth aspect comprises a base resin mixed with an antioxidant. Examples of the anti-aging agent include amine-based (for example, polymerized 2,2,4-trimethyl-1,2-dihydroquinoline) and phenol-based (for example, 4,4′-thiobis (6-t-butyl-m-cresol). )). According to the invention as set forth in claim 13, since the antioxidant is mixed with the base resin, deterioration of the non-halogen flame-retardant polyolefin resin composition over time is prevented. Can be prevented.

8. Tensile test of JIS-K7113 based on each composition component of Comparative Examples 1 to 5 and Conventional Examples 1 to 3
Each test result of the volume resistivity test of K6723 will be examined.

The 100% modulus in Tables 1, 2 and 3 is the tensile load applied to the test piece when the prepared press sheet (test piece) was stretched by 100% (when stretched to twice the length). (MPa). That is, the 100% modulus in Tables 1, 2 and 3 is obtained by measuring the tensile load when the test piece is stretched by 100%. Also, the tensile elongation in Tables 1, 2 and 3 is as follows:
Fix one end of the prepared press sheet (test piece), pull the other end, pull until the test piece is torn apart, and divide the length (elongation) when cut off by the original test piece length And the percentage (elongation). That is, the maximum elongation of the test piece when the test piece was stretched was determined. Further, the tensile strength (MPa) in Tables 1, 2 and 3
Indicates how much load (MPa) is pulled when pulled, the load when pulled,
That is, it is indicated by the maximum tensile load (N) per sectional area (mm ² ) of the test piece. Therefore, the mechanical strength can be determined from the magnitude of the tensile strength.

The volume resistivity in Tables 1, 2 and 3 is based on the volume resistivity test of JIS-K6723 specified in Japanese Industrial Standards. The volume resistivity is the electric resistance between two sides of a 1 cm ³ cube when a voltage is applied between the opposite sides. In the volume resistivity test of JIS-K6723, first, samples of the respective composition components shown in Tables 1, 2, and 3 are roll-kneaded and compression-molded into a sheet having a specified thickness (1.00 mm ± 0.15 mm). The obtained press sheet (test piece) is punched into a piece having a width and a length of 120 mm or more to obtain a test piece. The thickness of this test piece was measured at predetermined locations (5 locations) at room temperature, and the average value was determined to be the specified thickness (1.00 mm ± 0.15 m).
m). Further, the thickness of the test piece is required to be as uniform as possible over the whole, and the difference between the maximum thickness and the minimum thickness at the five measurement points of the thickness is required to be 0.1 mm or less. Then, electrodes were attached to the front and back surfaces of the test piece whose thickness was measured, and the electrodes were kept in a thermostat at 120 ° C. ± 3 ° C. for 30 minutes or more.
The above voltage is applied, and after charging for 1 minute, the volume resistance is measured. The volume resistivity is determined from the measured volume resistivity, the diameter of the electrode, and the thickness of the test piece.

The overall judgment is made based on the value of 100% modulus (MPa), the value of tensile elongation (%), the value of tensile strength (MPa), and the value of volume resistivity (Ω-cm). However, the reference value differs depending on the mixing ratio of the base resin obtained by mixing the olefin resin (PE) and the metal hydroxide (magnesium hydroxide).
