[polyolefine resin composition]

Fig. 1 and Fig. 2 used below are illustrated the schematical composition of polyolefine resin composition of the invention.

As described above, polyolefine resin composition of the invention contain polyolefin resin, hollow member, elastomer components and Modified polyolefin resin etc. and constitute.In addition, can also contain other ingredients as needed.Wherein, polyolefin resin of the invention Composition does not contain the affine ingredient of hollow member for significantly improving the compatibility on the surface of hollow member.

Fig. 1 is the cross-sectional view schematically constituted for indicating polyolefine resin composition of the invention.Fig. 2 is to indicate previous Polyolefine resin composition the cross-sectional view schematically constituted.

As shown in Figure 1, the polyolefine resin composition 50 of present embodiment is configured to that hollow member 52 is made to be dispersed in conduct In the polyolefin resin 51 of host material.It in this regard, is similarly constituted with previous polyolefine resin composition 60.

At this point, in the case where polyolefine resin composition 50 of present embodiment, thus it is speculated that go out, in the table of hollow member 52 Between face and polyolefin resin 51, binding part (not shown) is formed by modified polyolefin resin 54.

In addition, polyolefine resin composition 50 of the invention contains elastomer components 53.As shown in Figure 1, elastomer components 53 are dispersed in polyolefine resin composition 50, exist in around hollow member 52.It deduces, is present in hollow member 52 Around elastomer components 53 the polyolefin resin formed body that is made of polyolefine resin composition 50 applied with absorbing The mode of the kinetic energy of impact works.In addition, deducing, due to combining the surface of hollow member 52 and polyolefin resin 51 The modified polyolefin resin 54 come, the intensity of polyolefine resin composition 50 also improve.

It is hollow even if being applied with impact to the polyolefin resin formed body being made of polyolefine resin composition 50 as a result, Component 52 also can mitigate impact energy under the action of elastomer components 53 of impact resistance with higher.Meanwhile in utilization The intensity of the surface of empty component 52 and the combination of polyolefin resin 51, polyolefine resin composition 50 improves.Polyolefin tree as a result, Oil/fat composition 50 has the toughness for having both both intensity and impact resistance.As a result, it is believed that polyolefine resin composition 50 Impact resistance get higher.Therefore, especially as polyolefin resin formed body, not only for plane, even if setting stress is easy The construction of the root of the rib of concentration etc. can also shift to an earlier date the generation of pre- breakage-proof etc. by having higher impact resistance.

In addition, can be improved polyolefin resin formed body by by a part of fixation of polyolefin resin and hollow member Surface hardness.That is, the surface of hollow member 52 and polyolefin resin 51 by modified polyolefin resin 54 by combining And improve intensity.As a result, deducing, the surface hardness of polyolefin resin formed body is got higher.

In addition, as described above, the type of elastomer components 53 is not particularly limited.It is such as alkene in elastomer components 53 In the case where system, the compatibility compatible with polyolefin resin 51 is higher.Therefore, elastomer components 53 are good in polyolefin resin 51 Disperse well (for example, uniformly).It deduces as a result, due to the effect of elastomer components 53, effect, polyolefin resin formed body Obtain good impact resistance.

In contrast, in the case where elastomer components 53 are such as polystyrene, compared with olefin-based, with polyolefin tree The compatible compatibility of rouge 51 is lower.If compatibility is lower, elastomer components 53 can not divide well in polyolefin resin 51 It dissipates.Therefore, when initially being studied, the inventors of the present invention speculate that the impact resistance of polyolefin resin formed body may not mentioned It is high.However, research the result is that learn, be styrene in elastomer components 53 shown in 1~embodiment of embodiment 9 as be described hereinafter In the case where system, compared with olefin-based, more good impact resistance is obtained.About the reason, the inventors of the present invention's consideration is Because molecule of the elastomer components 53 of polystyrene not with polyolefin resin 51 is sufficiently mixed in polyolefin resin 51.By This speculates, it may be possible to which the molecule of elastomer components 53 plays good caoutchouc elasticity and improves impact resistance.

As described above, polyolefine resin composition 50 of the invention containing hollow member 52, elastomer components 53 and by The binding part that improved polyalkene is formed.Thereby, it is possible to realize the polyolefin resin with good impact resistance and surface hardness Composition 50.

On the other hand, as shown in Fig. 2, previous polyolefine resin composition 60, which contains, can significantly improve hollow member The hollow member of the compatibility on surface is affine ingredient.Therefore, hollow significantly improving as shown in the region as blacking in Fig. 2 Under the action of the hollow member of the compatibility on the surface of component is affine ingredient, it is formed with around hollow member 52 and polyolefin Very firm closed surface 61 between resin 51.It is applied to the polyolefin resin formed body being made of polyolefine resin composition 60 In the case where impact, closed surface 61 is difficult to the dispersion of kinetic energy caused by making to impact, is difficult to absorb impact.Therefore, for polyene For hydrocarbon resin composition 60, impact is starting point concentration with hollow member 52.As a result, it is believed that in previous polyolefin resin In composition 60, good impact resistance can not be obtained.

It should be noted that as described above, polyolefin resin, hollow member in polyolefine resin composition 50, elasticity The content (for example, containing ratio, compounding rate) of body ingredient and modified polyolefin resin is not particularly limited.I.e., it is possible to according to conduct The various conditions for forming type, purposes, size, use environment of polyolefin resin formed body of object etc. are set appropriately.

For example, the total weight of polyolefin resin, hollow member, elastomer components and modified polyolefin resin is set as 100 When weight %, as long as the content of hollow member is more than 1 weight % and in the range of 50 weight % or less.In addition, hollow The content of component is more preferable as long as more than 5 weight % and in the range of 30 weight % or less.As long as that is, 5 weight %~ In the range of 30 weight %, then it is easier to realize the lightweight as target.In addition, due to further can equably be kneaded, Therefore it is easier to maintain desired intensity.

When the content of hollow member is lower than 1 weight %, although additionally depending on various other conditions, polyolefin resin combination The weight rate of hollow member in object reduces.Therefore, it is impossible to fully obtain for light-weighted effect.On the other hand, in When the content of empty component is more than 50 weight %, the bulk density of the hollow member in polyolefine resin composition is opposite to be increased.Cause This, the behaviour although additionally depending on various other conditions, when manufacturing polyolefine resin composition, when making to be kneaded each ingredient sometimes The property made reduction.In addition, the mechanical property of the polyolefine resin composition made sometimes is (for example, impact resistance, tensile elongation Deng) reduce.

In addition, the sum of the content for elastomer components and modified polyolefin resin, by polyolefin resin, hollow member, When the total weight of elastomer components and modified polyolefin resin is set as 100 weight %, as long as more than 1.5 weight % and 35 weights In the range for measuring % or less.In addition, the content of elastomer components and modified polyolefin resin and it is more preferable in 5.5 weights It measures in % or more and the range of 25 weight % or less.

Wherein (in the range of 1.5 weight % or more and 35 weight % or less), as long as elastomer components are more than 1 weight % And 20 weight % range below.As long as in addition, elastomer components are more than 5 weight % and 20 weight % ranges below It is interior i.e. more preferable.As long as in addition, modified polyolefin resin is more than 0.5 weight % and in the range of 15 weight % or less. In addition, modified polyolefin resin is more preferably more than 0.5 weight % and in the range of 10 weight % or less.

When the content of elastomer components is lower than 1 weight %, although additionally depending on various other conditions, polyolefin resin group " concentration " for closing elastomer components contained in object not will increase (low).Therefore, for obtained polyolefine resin composition, have When expect the raising of impact resistance with being unable to fully.

On the other hand, when the content of elastomer components is more than 20 weight %, although additionally depending on various other conditions, gather " concentration " of elastomer components contained in olefin resin composition increases.In the case, polyolefine resin composition is resistance to Impact improves, but the ratio of the polyolefin resin as host material reduces.Therefore, having makes the strong of polyolefine resin composition Spend reduced worry.

In addition, when the content of modified polyolefin resin is lower than 0.1 weight %, although additionally depending on various other conditions, " concentration " of modified polyolefin resin contained in polyolefine resin composition not will increase (low).Therefore, poly- for what is obtained Olefin resin composition expects the raising of surface hardness with being unable to fully sometimes.

On the other hand, when the content of modified polyolefin resin is more than 15 weight %, although additionally depending on various other conditions, But " concentration " of modified polyolefin resin ingredient contained in polyolefine resin composition increases.In the case, polyolefin tree The surface hardness of oil/fat composition improves, but makes to improve as the polyolefin resin of host material and the adaptation of hollow member.Cause This, there is the worry for reducing the impact resistance of polyolefine resin composition.
