Description

Polyolefine resin composition and the vistanex formed body using it and use Its dust catcher

Technical field

This disclosure relates to it is suitable for the polyolefine resin composition of the resin-formed body of dust catcher part and uses it Vistanex formed body and use its dust catcher.

Background technology

It is excellent for the mechanical strength and molding processibility of the polyolefine resin composition of principal component with polypropylene etc., and be honest and clean Valency and light weight.Therefore, polyolefine resin composition is widely used in various fields.

Particularly, it is in the field of electrical article, it is desirable to lightweight.Therefore, the shaping of polyolefine resin composition is passed through The obtained part of resin-formed body (vistanex formed body) all the time as family's electrical article is widely used.

In recent years, in the field of family's electrical article, further lightweight is sought.Therefore, for example carried out making polyene in the past The wall thickness of hydrocarbon resin formed body reduces, reduces the research such as weight.

However, when wall thickness becomes too small, there is the worry of the reductions such as rigidity or the impact resistance of vistanex formed body.Cause This, in the past, such as known in No. 5542733 publications of Japanese Patent No. (following, be denoted as " patent document 1 ") etc. has：To polyolefin Resin-formed body, various fillers are added to suppress the reduction of rigidity or impact resistance etc. and realize light-weighted method.Now, make For filler, such as use the hollow packing for having inorganic system.It should be noted that as representational hollow packing, can enumerate The hollow packing of glass system.

In the vistanex formed body of patent document 1, as matrix material (mother metal), the polyolefin tree such as polypropylene is used Fat.Moreover, as hollow packing, formed with the first layer comprising silane coupler and Malaysia is included on the surface of hollow member Anhydride modified polyolefin resin and the second layer combined with first layer.That is, disclose and hollow packing is dispersed with vistanex Composition vistanex formed body.

That is, in the vistanex formed body of patent document 1, the surface for making hollow packing is two-layer structure.Moreover, especially It is the maleic anhydride modified vistanex by being used as the second layer, realizing the breakage of hollow packing prevents the raising of effect.Enter And by making the surface of hollow packing be two-layer structure, make to improve with the adaptation of the vistanex as matrix material.Also Disclose, it is possible thereby to improve the intensity of vistanex formed body.

But, it is known that using technology disclosed above, it can not fully improve the impact resistance of vistanex formed body.

Particularly, in use, user holds at least a portion (handle part) and used, hand takes family's electrical article of type In the case of, in use, there is the worry of the part in addition to handle part of an electrical article and the object collision of surrounding.According to using feelings Condition, have from the hand of user departs from and worry that family's electrical article is fallen.For example, in the case that family's electrical article is dust catcher, dust suction Inhalation apparatus (suction nozzle) of device etc. has the possibility with the collision of various objects in use.

Therefore, the hand of the possibility fallen when having the collision with other objects, using is taken in family's electrical article of type etc., for The part easily collided, it is desirable to higher than common impact resistance.

However, in the case of the vistanex formed body of patent document 1, hollow packing and matrix material (polyolefin tree Fat) adaptation it is high, therefore, there is the worry that impact resistance reduces.Thus, for example there is inhalation apparatus that can not realize dust catcher etc. The worry of required sufficient impact resistance.

The content of the invention

The disclosure provides：Be suitable as an electrical article part, polyolefine resin composition and use its polyolefin Resin-formed body and the dust catcher using vistanex formed body.

The polyolefine resin composition of the disclosure contains：Vistanex, granular hollow member and elastomer components. It is following to form：The surface of hollow member has non-compatibility to vistanex, and the polyolefine resin composition does not contain Hollow member is affine composition.

According to above-mentioned composition, polyolefine resin composition as the vistanex of matrix material (mother metal) for being mixed with Hollow member and elastomer components.Now, hollow member does not contain the affine composition of hollow member, therefore, to vistanex not Show compatibility.

Therefore, by the mixing of hollow member, the lightweight of polyolefine resin composition can be carried out.And then hollow structure The surface of part is non-compatibility, accordingly, it is difficult to vistanex set.Therefore, it is made up of polyolefine resin composition poly- Even if olefin resin formed body applies impact, the interface of hollow member is also easily slided relative to vistanex.Thus, with poly- Olefin resin compared with the vistanex formed body that hollow member set is formed, can be greatly reduced using hollow member as rise The possibility put and cracked in vistanex formed body.

And then polyolefine resin composition contains elastomer components.Elastomer components, can be with by being combined with hollow member Impact resistance is improved tremendously.As a result, using the vistanex formed body of polyolefine resin composition can realize into The lightweight of one step and obtain excellent impact resistance.Therefore, can be by polyolefine resin composition particularly suitable for requiring The vistanex formed body of impact resistance is family's electrical article part etc..

In addition, the vistanex formed body of the disclosure is at least uses the household electrical appliances system that forms of polyolefine resin composition Product part.As vistanex formed body, such as the inhalation apparatus of dust catcher can be enumerated etc..

In addition, the standby part being made up of vistanex formed body of the dust catcher of the disclosure.

According to the composition of the disclosure, it can obtain being suitable as an electrical article part, lightweight can be realized and excellent Impact resistance polyolefine resin composition.Thus, it is possible to realize：Seek lightweight and it is high it is impact resistance, using poly- The vistanex formed body of olefin resin composition and the dust catcher using vistanex formed body.

[vistanex]

As long as contained vistanex is to make at least one kind of polymerizing olefin monomers in the polyolefine resin composition of the disclosure The polymer formed is just not particularly limited.As long as typically for make ethene, propylene (propylene), 1- butylene, 1- amylenes, 1- oneself Polymer obtained from least one kind of polymerization of the alpha-olefins such as alkene, 4-methyl-1-pentene, 1- octenes.

As vistanex, such as polyethylene kind, PP type, ethylene copolymer etc. can be enumerated.As specific Polyethylene kind, high density polyethylene (HDPE) (HDPE), low density polyethylene (LDPE) (LDPE), straight-chain low density polyethylene can be enumerated (LLDPE), ultra-low density polyethylene (VLDPE, ULDPE) etc..As PP type, homo-polypropylene, random poly- third can be enumerated Alkene, block polypropylene etc..As ethylene copolymer, ethylene propylene copolymer, Ethylene Vinyl Ester Copolymers, second can be enumerated Alkene vinyl silane compound copolymer, ethene (methyl) acrylic compounds copolymer etc..Now, vistanex Can be used only a kind, can also it is appropriately combined two or more and use.

It should be noted that the vistanex as the disclosure, in polyethylene kind, PP type, ethylene copolymer etc. In, the particularly preferred PP type low with the compatibility of double glazing.

It is contained in addition to polypropylene in random polypropylene or block polypropylene in PP type for PP type The species of monomer be not particularly limited.For example, can be the alpha-olefins such as ethene, or example removes in ethylene copolymer Polymerizable compound outside alpha-olefin.In addition, above-mentioned ethylene copolymer can be random copolymer, block copolymer, also may be used Think graft copolymer.

And then for vistanex such as molecular weight (number-average molecular weight Mn or weight average molecular weight Mw), vertical structure rule The physical property such as whole property (in the case that there is side chain) or (non-) crystallinity, density (proportion), glass transition point (Tg), without spy Do not limit.Therefore, the physical property of vistanex can be appropriate according to the species of family's electrical article part as shaping object Setting.

It should be noted that when wanting to make a house electrical article part lightweight as far as possible, it is preferred that side considers and other things Property take into account, side selection density (proportion) is tried one's best small vistanex.

[hollow member]

As long as contained hollow member is graininess in the polyolefine resin composition of the disclosure and inside is hollow shape Just it is not particularly limited.The material of hollow member is not particularly limited, and can typically enumerate inorganic system's material such as glass, ceramics Material.Specifically, as hollow member, such as the hollow packing (double glazing) of the glass systems such as Glassbubbles can be enumerated Deng.The surface of double glazing is low (having non-compatibility) to the compatibility of vistanex, therefore, is particularly suitable as this public affairs The hollow member opened.

In addition, for hollow member physical property such as average grain diameter, compressive resistance, real density, heat endurance, without spy Do not limit.Therefore, the physical property of hollow member can suitably be set according to family's electrical article as shaping object with the species of part It is fixed.

In the disclosure, the surface of hollow member is formed as follows as described above：There is non-compatibility to vistanex.

It should be noted that non-compatibility for example can be by making the surface of hollow member and the surface point of vistanex Contact angle θ (the contact angle θ of water) when not contacted with water quantizes.That is, non-compatibility can be by using the hollow structure of composition The material of part or the sample that vistanex is shaped to regulation shape, contact angle θ is determined using known contact angle meter, So as to be quantized to evaluate.

Typically, the vistanex of the disclosure has the characteristic that the contact angle θ of water is fallen into the range of 85~100 °.Example Such as, representational vistanex is that the contact angle θ of polyacrylic water is fallen into the range of 95~98 °.In addition, the water of polyethylene Contact angle θ be 88 ° or so.Therefore, it is possible to the water of matrix material (resin) that is used as the vistanex of the disclosure In the range of as long as contact angle θ is 85~100 °.

On the other hand, if the contact angle θ of the water on the surface of hollow member be less than 10 °, i.e. 0~10 ° in the range of be Can.And then in the range of the contact angle θ of water is if less than 5 °, i.e. 0~5 °, then more preferably.

Herein, with contact angle θ judge the compatibility to water, i.e. it is hydrophilic whether there is when, typically, by contact angle θ be 30 ° work Judge for critical value.That is, contact angle θ then judges there is hydrophily if less than 30 °.Moreover, generally, if contact angle θ For less than 10 °, then judge the surface of measure has very high compatibility (Superhydrophilic) to water.On the other hand, contact angle θ is such as Fruit is more than 90 °, then judges that determined surface has property, the i.e. water repellency for making water resilience.

It should be noted that hydrophily of the vistanex of the disclosure without the degree for playing water repellency.It is and hollow The surface of component possesses the state for playing Superhydrophilic as described above.

That is, whether the surface of the hollow member of the disclosure has non-compatibility can be according to contact angle θ vistanex Quantized to evaluate.

[elastomer components]

Contained elastomer components are by can be with the polyene as matrix material in the polyolefine resin composition of the disclosure The composition of hydrocarbon resin mixing is formed.Therefore, for elastomer components, the shape included using the composition as polyolefine resin composition State, when being shaped to vistanex formed body, as long as not causing substantial influence, then it can include arbitrary composition.

As elastomer components, such as thermoplastic elastomer (TPE), diene series rubber, non-diene series rubber etc. can be enumerated.Make For specific thermoplastic elastomer (TPE), styrene series elastomer, olefin-based elastomer, vinyl chloride elastomer, amino can be enumerated Formic acid ester based elastomers, acid amides based elastomers etc..As diene series rubber, vinyl benzene rubber, isoprene can be enumerated Rubber, butadiene-based rubber etc..As non-diene series rubber, butyl rubber, ethylene propylene rubber, ethylene, propylene two can be enumerated Alkene rubber, urethane rubber etc..Now, elastomer components can be used only a kind, can also it is appropriately combined two or more and Use.

It should be noted that the elastomer components as the disclosure, thermoplastic elastomer (TPE), diene series rubber, non-diene series In rubber etc., the elastomer or rubber or elastomer or rubber comprising alkene structures of styryl structures are particularly preferably included. And then among them, particularly preferred styrene series elastomer.

As long as the above-mentioned elastomer comprising styryl structures or rubber comprising styrene skeleton and have caoutchouc elasticity can Think any.Specifically, such as styrene series elastomer or vinyl benzene rubber etc. can be enumerated.

Styrene series elastomer (styrene butadiene thermoplasticelastomer (TPE-S；Styrene-Butadiene Thermoplastic Elastomer)) as long as including polystyrene, polybutadiene or polyisoprene etc..Need to illustrate , the principal component that polystyrene is formed in molecule is hard segment.Polybutadiene or polyisoprene form in molecule it is secondary into Divide i.e. soft chain segment.

In addition, as long as vinyl benzene rubber has styrene skeleton such as being SB (SBR) Diene series rubber can be thought arbitrarily.

As specific styrene series elastomer or vinyl benzene rubber, such as styrene-butadiene fourth can be enumerated Alkene-styrene block copolymer (SBBS), SBS (SBS), styrene-ethylene fourth Alkene-styrene block copolymer (SEBS), hydrogenated styrene-butadiene rubber (HSBR), styrene-ethylene butylene-ethene Block copolymer (SEBC), styrene-ethylene propylene-styrenic block polymers (SEPS) etc..Now, vinyl benzene rubber Or styrene series elastomer can be used only a kind, can also it is appropriately combined two or more and use.And then vinyl benzene rubber or It can be used in styrene series elastomer with appropriately combined elastomer in addition.

It should be noted that the styrene series elastomer as the disclosure, be particularly preferably selected from by above-mentioned SEBS, SEPS, At least one kind of styrene series elastomer in the group of SBS, SEB (styrene-ethylene-butadiene block copolymer) composition.That is, benzene second The easy differential of alkene based elastomers dissipates, and therefore, easily plays the performance as rubber, therefore more preferably.

It should be noted that commonly known, styrene series elastomer is difficult to the particularly polypropylene in vistanex It is compatible.Therefore, in the polyolefine resin composition of the disclosure, for vistanex, mixing has the surface of non-compatibility Hollow member.That is, for matrix material, by two kinds be difficult to mix used into subassembly.Thus, as described later, can be with The impact resistance of gained vistanex formed body is improved tremendously.

As long as in addition, elastomer or rubber comprising alkene structures comprising olefin skeletal as hard segment, comprising rubber or Elastomer components can be thought arbitrarily as soft chain segment.Specifically, such as olefin-based elastomer or olefin-based rubber can be enumerated Glue etc..

As long as olefin-based elastomer does not just have comprising the hard segment being made up of polyolefin and the soft chain segment being made up of rubber constituent It is particularly limited to.Specifically, such as compounding (blending) ethylene-propylene can be enumerated in the polyolefin such as polypropylene or polyethylene The olefin-based elastomer that the rubber constituents such as rubber form.Furthermore it is possible to enumerate compounding polyolefin and rubber constituent and partial cross-linked The olefin-based elastomer formed；It is compounded polyolefin and rubber constituent and the fully crosslinked olefin-based elastomer formed etc..And then can Make olefinic monomer, with the olefin-based elastomer that forms of monomer copolymerization as rubber constituent etc. to enumerate.Now, olefin-based elasticity Body can be used only a kind, can also it is appropriately combined two or more and use.

Now, as olefin-based rubber, as long as just not having comprising vinyl monomer or propylene monomer etc. and with caoutchouc elasticity It is particularly limited to.Specifically, as olefin-based rubber, such as ethylene propylene rubber (EPR, EPM), ethylene, propylene two can be enumerated Alkene rubber (EPT, EPDM), vinyl-vinyl acetate copolymer (ethylene-vinylacetate rubber) etc..

It should be noted that above-mentioned olefin-based elastomer or olefin-based rubber bag contain the structure from alkene.Therefore, this public affairs The matrix material for the polyolefine resin composition opened i.e. vistanex has compatibility.It is thus regarded that vistanex and bullet Property body composition compatibility improve.

In contrast, the surface of hollow member is as described above, there is non-compatibility to vistanex.Therefore, it is elastic In the case that body composition is olefin-based elastomer, elastomer components, which are also turned into, has non-compatibility.It is thus regarded that based on hollow The effect of the compounding of component is well played.As a result, the polyolefin tree obtained by polyolefine resin composition can be improved The impact resistance of fat formed body.

Wherein, shown in embodiment as be described hereinafter, it is known that, for elastomer components, styrene series elastomer (embodiment 6) with Olefin-based rubber (embodiment 7) is compared, and plays good impact resistance.Result, it is believed that with elastomer components to vistanex Compatibility it is high when compare, it is further good to the effect of the impact resistance of the compounding based on hollow member when compatibility is low Ground is played.

[other compositions]

The polyolefine resin composition of the disclosure in addition to above-mentioned, vistanex, hollow member and elastomer components, In the range of the effect of the disclosure, effect is not damaged, known other compositions can be contained.

Specifically, as other compositions, such as antioxidant, light stabilizer, ultra-violet absorber, anti-quiet can be enumerated Electric agent, dispersant, nucleator, plasticizer, nertralizer, colouring agent (pigment, dyestuff), foaming agent, lubricant, fire retardant, anti-copper Evil agent, packing material (excluding above-mentioned hollow member) etc..

Now, in other compositions, hollow member of the surface without raising hollow member to the compatibility of vistanex Affine composition.

If during composition affine comprising hollow member, the surface of hollow member has well affine to vistanex Property.Now, hollow member is bonded to the vistanex as matrix material.Pass through set, as described later, vistanex The impact resistance of formed body reduces.As a result, using hollow member is starting point and vistanex formed body easily ruptures.

That is, the above-mentioned affine composition of hollow member is as with compatibility of the surface to vistanex for improving hollow member The composition of property be defined.As the affine composition of specific hollow member, it is not particularly limited, such as surface can be enumerated and changed Matter agent, modified resin etc..

Surface modifier is used for the surfaction for making hollow member, and directly improves surface to the affine of vistanex Property.As surface modifier, such as silane coupler (with reference to patent document 1) etc. can be enumerated.

In addition, modified resin is in the same manner as surfactant, comprising：There is the position of compatibility to the surface of hollow member With the position to vistanex with compatibility.Therefore, modified resin is folded between hollow member and vistanex When, the compatibility on the surface of hollow member improves indirectly.As modified resin, such as maleic anhydride modified polyene can be enumerated Hydrocarbon (with reference to patent document 1 and comparative example 2 described later) etc..

It should be noted that in the case that the surface of hollow member does not have sufficient non-compatibility to vistanex, Or want in the case of further improving non-compatibility (i.e., it is desirable to reduce compatibility as far as possible), in polyolefine resin composition Following composition can also be included.Specifically, can also include：With the affine composition of hollow member have adverse effect into Point, i.e., the composition that makes the surface of hollow member be reduced to the compatibility of vistanex and (make non-compatibility raising).

[polyolefine resin composition]

Hereinafter, using Figure 1A and Figure 1B, the schematical composition of the polyolefine resin composition of the disclosure is illustrated.

The polyolefine resin composition of the disclosure contains vistanex, hollow member and elastomer components as described above And form.And then also contain other compositions as needed.But the polyolefine resin composition of the disclosure does not contain hollow structure Part is affine composition.

Figure 1A is the sectional view of the schematical composition for the polyolefine resin composition 50 for showing the disclosure.Figure 1B is to show The sectional view of the schematical composition of conventional polyolefine resin composition 60.

The polyolefine resin composition 50 of the disclosure as shown in Figure 1A, in the vistanex 51 as matrix material In be dispersed with hollow member 52 and form.At this point, it is same composition with conventional polyolefine resin composition 60.

Moreover, in the polyolefine resin composition 50 of the disclosure, the surface of hollow member 52 has to vistanex 51 Non- compatibility, and then, as described above, without the affine composition of hollow member.Therefore, hollow member 52 is difficult to and vistanex 51 is closely sealed.Think, between the surface of hollow member 52 and vistanex 51 formed with it is such shown in Figure 1A dotted line, Interface 54.Thus, even if applying impact, hollow member to the vistanex formed body being made up of polyolefine resin composition 50 52 are easily slided by interface 54 in vistanex 51.As a result, the kinetic energy of impact is easily dispersed without concentrating.

And then the polyolefine resin composition 50 of the disclosure includes elastomer components 53.Such as Figure 1A institutes of elastomer components 53 Show like that, be scattered in polyolefine resin composition 50, exist in around hollow member 52.Now, thus it is speculated that：Hollow member Existing elastomer components 53 in a manner of absorbing the kinetic energy of the impact applied to vistanex formed body to play around 52 Effect.

Specifically, it is high to the compatibility of vistanex 51 in the case that elastomer components 53 are, for example, olefin-based.Cause This, is scattered in vistanex 51 elastomer components 53 good (such as uniform).Thus speculate：Vistanex formed body Good impact resistance can be obtained using the action effect of elastomer components 53 (with reference to embodiment 7 described later).

On the other hand, in the case that elastomer components 53 are, for example, polystyrene, compared with olefin-based, to vistanex 51 compatibility is low.If compatibility is low, elastomer components 53 will not be well dispersed within vistanex 51.Therefore, Originally, disclosure people etc. speculates for research：The impact resistance of vistanex formed body may not improve.However, ground Study carefully, as a result understand, shown in 1~embodiment of embodiment 6 as be described hereinafter like that, in the case that elastomer components 53 are polystyrene, Compared with olefin-based, better impact resistance can be obtained.For its reason, disclosure people etc. think be probably due to, In vistanex 51, the elastomer components 53 of polystyrene are deficiently mixed to the molecule of vistanex 51.Supposition can Can the molecules of thus elastomer components 53 play good caoutchouc elasticity, improve impact resistance.

As more than, for the polyolefine resin composition 50 of the disclosure, the surface of hollow member 52 has to matrix material Non- compatibility, and include elastomer components 53.Thus, it is possible to realize the polyolefine resin composition with good impact resistance 50。

On the other hand, as illustrated in figure ib, conventional polyolefine resin composition 60 includes the affine composition of hollow member. Therefore, as being filled out in Figure 1B shown in black region, around hollow member 52, due to the effect of the affine composition of hollow member And form the firm closed surface 61 with polyolefine resin composition 60.In the vistanex to polyolefine resin composition 60 In the case that formed body applies impact, closed surface 61 is difficult to the kinetic energy for disperseing, absorbing impact.Therefore, polyolefine resin composition 60 impact concentration with hollow member 52 for starting point.Its result thinks that conventional polyolefine resin composition 60 can not be realized good Good impact resistance.

It should be noted that vistanex, hollow member and elasticity as described above, in polyolefine resin composition The content (such as containing ratio, compounding rate) of body composition is not particularly limited.I.e., it is possible to according to the polyolefin tree as shaping object Each conditions such as the species of fat formed body, purposes, size, use environment and suitably set.

For example, when the gross weight of vistanex, hollow member and elastomer components is set into 100 weight %, hollow structure In the range of as long as the content of part is 1~50 weight %.And then the content of hollow member is if 5~30 weight %'s In the range of, then more preferably.That is, in the range of if 5~30 weight %, then it is easier to realize target lightweight.Furthermore it is possible to Further equably it is kneaded, therefore, it is easier to maintain desired intensity.

That is, when the content of hollow member is less than 1 weight %, other each conditions, but polyolefine resin composition are additionally depended on In the weight rate of hollow member diminish.Therefore, it is impossible to fully obtain to light-weighted effect.On the other hand, hollow member Content more than 50 weight % when, in polyolefine resin composition it is hollow member, bulk density is relative becomes big.Therefore, also Depending on other each conditions, but the workability during mixing of each composition during polyolefine resin composition manufacture reduces sometimes.Enter And the mechanical property of gained polyolefine resin composition reduces sometimes.

In addition, for the content of elastomer components, the gross weight of vistanex, hollow member and elastomer components is set For 100 weight % when, as long as the content of elastomer components be 1~30 weight % in the range of.And then elastomer components Content is more preferably in the range of 5~20 weight %.That is, in the range of if 5~20 weight %, then target is more easily achieved Weight reduction rate.And then the possibility for reaching desired intensity can be improved.

That is, when the content of elastomer components is less than 1 weight %, other each conditions are additionally depended on, but vistanex combines " concentration " of contained elastomer components is not high (low) in thing.Therefore, sometimes can not be abundant in gained polyolefine resin composition It is expected that the raising of impact resistance.

On the other hand, when the content of elastomer components is more than 30 weight %, other each conditions, but polyolefin tree are additionally depended on " concentration " of contained elastomer components uprises in oil/fat composition.Now, the impact resistance of polyolefine resin composition improves, but Ratio as the vistanex of matrix material reduces.Therefore, the intensity decreases of polyolefine resin composition are worried.In addition, Elastomer components are relatively expensive compared with other compositions.Therefore, when the content of elastomer components is more than 30 weight %, also carry on a shoulder pole The high cost of heart polyolefine resin composition.

That is, the polyolefine resin composition of the disclosure is free of other compositions, only comprising vistanex, hollow member and bullet During property body composition, when the gross weight of vistanex, hollow member and elastomer components is set into 100 weight %, polyolefin tree In the range of as long as the content of fat is 20~98 weight %.And then the content of vistanex is if it is considered that double glazing With the difference of the addition of elastomer, then more preferably in the range of 50~90 weight %.

When the content of vistanex is less than 20 weight %, other each conditions, but the ratio drop of matrix material are additionally depended on It is low.Therefore, the intensity decreases of polyolefine resin composition are worried.On the other hand, the content of vistanex is more than 98 weight % When, additionally depend on other each conditions, but worry can not sufficiently to measure in polyolefine resin composition containing hollow member and At least one of elastomer components.Therefore, worry that the lightweight of polyolefine resin composition, impact resistance reduce.

It should be noted that the polyolefine resin composition of the disclosure can also contain except vistanex, hollow member With the other compositions outside elastomer components.The surface for being used for improving hollow member is free of in other compositions to vistanex The affine composition of hollow member of compatibility.

Now, the content of other compositions is not particularly limited.I.e., it is possible to according to addition other compositions purpose or its Species of his composition etc. and be properly added necessary amount.

[manufacture method of polyolefine resin composition]

Hereinafter, the manufacture method of the polyolefine resin composition of the disclosure is illustrated.

First, at least by vistanex, hollow member and elastomer components and other compositions as needed with Arbitrary order, arbitrary compounding amount are compounded.Now, exclude for the surface for improving hollow member to vistanex The affine composition of hollow member of compatibility.

Then, each composition being compounded for example is kneaded in known kneading machine.Now, made as needed Grain.

Then, will be for example molded by the mixture being kneaded in known forming machine.Thus, manufacture has regulation Compounding amount polyolefine resin composition.

It should be noted that the kneading machine used during compounding can be adapted to use known kneading machine.Specifically, such as Single screw extrusion machine, double screw extruder, super mixer, Henschel mixer, Banbury mixer, roll-type can be enumerated to mix The kneading machines such as conjunction machine, brabender plasticorder, kneader.These kneading machines can possess the composition that can be granulated.In addition, in profit , can also be by vistanex, hollow member, elastomer components and its being compounded as needed before being kneaded with kneading machine At least any one is kneaded and manufactured in advance in his composition.

That is, the polyolefine resin composition of the disclosure by vistanex, hollow member and elastomer components it is each into Point mixing or after being kneaded the granulation carried out and obtain.

Then, gained polyolefine resin composition is molded for example using known various forming machines with vistanex The form of body is molded.As specific forming machine, it is not particularly limited, such as injection (mo(u)lding) machine can be used, be extruded into Type machine, panel forming machine, vacuum forming machine etc..

Thus, vistanex formed body is at least formed using polyolefine resin composition.Now, comprising except polyolefin Material (such as antioxidant etc.) outside resin combination, can also form vistanex formed body.Thus, it is possible to obtain Vistanex formed body with good impact resistance.

Moreover, gained vistanex formed body is not particularly limited, the evaluation of the impact resistance of following middle explanation is used Method etc. is evaluated.

Illustrated such in embodiment as be described hereinafter etc. in present embodiment, first, what will be obtained by the above method is poly- Olefin resin composition is shaped to the thick tabulars of such as 1.6mm, forms the test film of vistanex formed body.

Then, the test film of formation is stood 3 hours for example in thermostat with -10 DEG C.Afterwards, relative to test film, Fall 250g weight.

Then, the maximum height that measurement test film is not destroyed.Thus, based on maximum height, evaluation test piece (polyolefin Resin combination) impact resistance.Now, the numerical value of maximum height is bigger, and impact resistance is more excellent.

It should be noted that in the disclosure, polyolefine resin composition considers the application being in electrical article part.Cause This, if for be more than 100cm with maximum height characteristic polyolefine resin composition.

That is, when maximum height is less than 100cm, can only obtain with having carried out light-weighted conventional gather using hollow member Olefin resin composition is equal extent or the impact resistance below it.It is therefore preferable that at least have maximum height be 100cm with On impact resistance polyolefine resin composition.It should be noted that the upper limit of maximum height is not particularly limited, but it is expected Numerical value is larger.However, the upper limit in physical property is limited according to the composition of polyolefine resin composition.
