Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-attenuation material composition, and more particularly, to a vibration-absorbing or sound-absorbing material applied to a sound insulation wall of an acoustic room, a sound insulation partition of a building structure, a sound insulation wall of a vehicle, and the like. The present invention relates to a high damping material composition as a vibration material and a soundproofing material.

[0002]

2. Description of the Related Art A polymer material as a high-damping material composition of this type is a typical viscoelastic material, and when the material microparts vibrate for any reason, each material micropart becomes A complex sinusoidal distortion (ε ^* ) is generated, which results in a complex sinusoidal stress (σ ^* ). The complex elastic coefficient (E ^* ) is obtained by taking these ratios as shown in the following equation. Complex modulus of elasticity (E ^* ) = complex sinusoidal stress (σ ^* ) / complex sinusoidal strain (ε ^* )

The real part of the complex elastic modulus (E ^* ) is defined as the storage elastic modulus (E ') relating to the elastic properties of the material, and the imaginary part thereof is the loss elasticity relating to the viscous properties of the material. The loss tangent (tan δ) is defined as the coefficient (E ″).
As shown in the following equation, these ratios are obtained. Loss tangent (tan δ) = loss elastic modulus (E ″) / storage elastic modulus (E ′)

The loss coefficient (hereinafter simply referred to as “tan δ”) is one of the factors that determine the soundproofing / damping characteristics. The higher the value, the more the mechanical energy is absorbed or released as electric or thermal energy. Thus, it is known to exhibit mechanical properties such as excellent sound absorbing properties and vibration damping properties. The value determined as tan δ of the high damping material composition is 0.5 or more, preferably 1.0 or more.

Therefore, the applicant of the present application has proposed the required characteristic (ta).
As a high attenuation material composition exhibiting a high tan δ satisfying nδ ≧ 1), in Japanese Patent Application No. 9-12387, an additive is dispersed in a base polymer material at a predetermined volume ratio, and a heat treatment step and a molding step are performed. Proposed material is proposed. This high attenuation material composition uses N, N-dicyclohexylbenzothiazyl-2-sulfenamide (manufactured by Sanshin Chemical Industry Co., Ltd .: trade name “Suncellar DZ”) as a vulcanization accelerator as an additive. Chlorinated polyethylene as the base polymer material (manufactured by Showa Denko KK: trade name "Eraslen 40"
1A ”), and its tan δ increases as the amount of the vulcanization accelerator increases.

[0006] Furthermore, the present applicant has filed Japanese Patent Application No. 9-215.
No. 746 and Japanese Patent Application No. 9-215747, the mixture of the above-mentioned additive and base polymer material is further provided with:
By adding diethylthiourea or N-cyclohexylbenzothiazyl-2-sulfenamide as a vulcanization accelerator as an additive, the required characteristics of tan δ (t
An δ ≧ 1.0) and a material capable of suppressing the change with time are proposed.

[0007]

However, in addition to the additives disclosed in Japanese Patent Application Nos. 9-12387, 9-137665, 9-215746 and 9-215747. Using a sulfur accelerator (N, N-dicyclohexylbenzothiazyl-2-sulfenamide),
A high attenuation material composition using chlorinated polyethylene for the base polymer material, if the amount of the additive is increased,
The tan δ increases with that, but if the tan δ is too large, a processing problem will arise. That is, the amount of the additive is limited. Therefore, there is a limit to the value of tan δ that can be expressed, and the desired high attenuation performance cannot be obtained. On the other hand, since additives are relatively expensive, there is also a problem in that if they are used in large amounts, production costs will increase.

The high attenuation material compositions disclosed in Japanese Patent Application Nos. 9-12387 and 9-137665 are:
The vulcanization accelerator (additive N, N-
Dicyclohexyl benzothiazyl-2-sulfenamide) crystallizes as it is or bleeds out (bleeds) to the surface of the damping material substrate, and further crystallizes,
It has been found to decrease over time.

Therefore, when the value of tan δ is increased by adding a large amount of a vulcanization accelerator (additive), the value decreases with time. In particular, when the vulcanization accelerator is added in a large amount, bleeding is more likely to occur, and the change with time is increased. That is, simply adding a vulcanization accelerator or adding a large amount of the vulcanization accelerator does not increase the service life.

It is an object of the present invention to provide a high-attenuation material composition having a loss tangent (tan δ) characteristic higher than that of the conventional art, and in which the deterioration of the attenuation performance due to aging is suppressed. is there. Thereby, it is intended to maintain high and stable damping performance over a long period of time.

[0011]

In order to solve this problem, a high attenuation material composition according to the present invention is characterized in that at least two or more additives are blended in a base polymer material having a polar side chain. Things. That is, the additive is composed of multiple components.

In this case, the "base polymer material" having a polar side chain includes natural rubber, modified natural rubber, grafted natural rubber, cyclized natural rubber, chlorinated natural rubber, styrene-butadiene rubber, chloroprene rubber, acrylonitrile -Butadiene rubber, carboxylated nitrile rubber,
Nitrile rubber / vinyl chloride resin blend, nitrile rubber / EPDM rubber blend, butyl rubber, brominated butyl rubber, chlorinated butyl rubber, ethylene-vinyl acetate rubber,
Rubber materials such as acrylic rubber, ethylene-acryl rubber, chlorosulfonated polyethylene, chlorinated polyethylene, epichlorohydrin rubber, epichlorohydrin-ethylene oxide rubber, methyl silicone rubber, vinyl-methyl silicone rubber, phenyl-methyl silicone rubber, and fluorosilicon rubber; Polystyrene-based thermoplastic elastomer, polyvinyl chloride-based thermoplastic elastomer, polyolefin-based thermoplastic elastomer, polyurethane-based thermoplastic elastomer, polyester-based thermoplastic elastomer, polyamide-based thermoplastic elastomer, vinyl chloride-based thermoplastic elastomer, fluororubber-based thermoplastic Elastomers, thermoplastic elastomer materials such as chlorinated polyethylene elastomers, polyvinyl chloride, chlorinated polypropylene, polyvinyl chloride , Polyvinyl acetate, polyvinyl alcohol, polyvinyl fluoride, polyvinylidene fluoride, polyacrylonitrile, polymethyl methacrylate, styrene-acrylonitrile copolymer, acrylonitrile-butadiene-styrene terpolymer, vinyl chloride At least one or two or more selected from polymer resin materials such as vinyl acetate copolymer, acrylic / vinyl chloride graft copolymer, ethylene / vinyl chloride copolymer, ethylene / vinyl alcohol, and chlorinated vinyl chloride; Base polymer materials are mentioned as suitable.

[0013] Further, as the "additive", the
It is desirable to use two or three amine compounds selected from tertiary amines or tertiary amines. This is because the material composition can be provided with damping performance. Such “additives” include N-
Cyclohexylbenzothiazyl-2-sulfenamide, N-tert-butylbenzothiazyl-2-sulfenamide, N-oxydiethylenebenzothiazyl-2
Sulfenamide-based additives such as -sulfenamide, N, N-dicyclohexylbenzothiazyl-2-sulfenamide, 2- (2′-hydroxy-3 ′-(3 ″,
UV absorbers such as 4 ", 5", 6 "-tetra-hydrophthalimido-methyl) -5'-methylphenyl) -benzotriazole, 2- (N, N-diethylthiocarbamoylthio) benzothiazole, 2- ( Thiazole additives such as 4'-morpholinodithio) benzothiazole, thiurams such as tetraethylthiuram disulfide and tetrabutylthiuram disulfide, 1- [N, N-
At least two additives selected from rust preventives such as bis (2-ethyl-hexyl) aminomethyl] benzotriazole and curing accelerators such as 2,4,6-tri (dimethylaminomethyl) phenol are preferable. It is mentioned as a thing.

In this case, a particularly preferable combination of the compounding components is that at least one of at least two or more kinds of additives to be added to the base polymer material having a polar side chain is a benzotriazole-based additive. There may be mentioned those in which the other additive is a sulfenamide-based additive or a thiazole-based additive. This is because the benzotriazole-based additive improves the damping performance of the material base in which the benzotriazole-based additive is blended. Further, the reason why two or more kinds of additives are blended is that the change with time of the damping performance becomes small.

According to the high damping material composition having the above-described structure, reversible and uniform interaction acts between the chain molecules of the base polymer material having polar side chains and the plurality of additives, so that the damping property is reduced. improves. Further, by mixing a plurality of additives, tan δ becomes high due to the synergistic effect. Furthermore, the crystallization of each compound component and the bleeding phenomenon of the additive on the surface of the material base are suppressed by the melting point drop phenomenon in the multi-component system. Thereby, the high attenuation material composition according to the present invention has a tan
Since the change with time of δ is suppressed, good damping performance is maintained, and excellent mechanical properties such as sound absorption and vibration resistance are exhibited.

"Noxeller TET-G (trade name)" and triazole-based 1- [N, N-bis (2-ethyl-hexyl) aminomethyl] benzotriazole were added to "BT-LX (manufactured by Johoku Chemical Co., Ltd.) Product name)].

First, the product of the present invention (Example 1) was manufactured by the following steps. That is, in the first embodiment, Eraslen 401A is provided with Suncellar DZ and Smisorb 25.
No. 0 is kneaded and kneaded, and the kneaded material is heated and molded by a hot press machine in a predetermined mold at a temperature of 100 to 200 ° C. for about 10 minutes. The temperature condition is 1
70 ° C is adopted.

The products of the present invention (Examples 2 to 6) are all manufactured by the same steps as in Example 1, but are different in the components. Example 2 uses Eraslen 4
01A is obtained by blending Sumisorb 250 and Noxeller 64 in Example 3, and Example 3 is obtained by blending Sumisorb 250 and Noxeller MSA-G with Eraslen 401A. Further, in Example 4, Sumisorb 250 and Noxeller TET-G were mixed with Eraslen 401A. In the fifth embodiment, the Noxeller 64 is added to Eraslen 401A.
And Noxeller TET-G, and Example 6 is a mixture of Eraslen 401A with Sumisorb 250 and BT-LX. The molding conditions and temperature conditions are the same as those in the first embodiment.

That is, all of the products of the present invention (Examples 1 to 4 and 6) except for Example 5 contained Sumisorb 250, which is a benzotriazole-based ultraviolet absorber, as components. One of the additives is used as a compounding component. The reason why the blending components were selected centering on Sumisorb 250 is that Sumisorb 250 has the property of improving the damping function.

As shown in Table 1, the compounding amount of the components in each of the examples was such that 70% by weight of Suncellar DZ used in Example 1 was 100% by weight of the base polymer material.
And Sumisorb 250 used in Example 1 was 3
Except for 0% by weight, all are 50% by weight, based on 100% by weight of the base polymer material.

Next, a comparative product (Comparative Example 1) is prepared by mixing Suncellar DZ with Eraslen 401A and kneading the kneaded material.
Heat molding at a temperature of 0 ° C. for about 10 minutes (temperature condition 17)
0 ° C). Other comparative products were produced by the same process as Comparative Example 1, but differed in the blending components. That is, in Comparative Examples (Comparative Examples 2 to 6), Eraslen 401A was provided with Suncellar DZ and Sumisorb 2 respectively.
50, Noxeller 64, Noxeller MSA-G, Noxeller TET-G, and BT-LX. The molding conditions and temperature conditions are the same as those described above. Further, as shown in Table 2, the blending amounts of the blending components of each comparative example were based on 100% by weight of the base polymer material.
All are 100% by weight.

Next, the tan δ of the product of the present invention and the comparative product before and after a change with time were measured using a spectrometer manufactured by Rheology Co., Ltd. (strain 10 μm (constant), frequency 15 Hz (constant)). Then, from the measured tan δ before and after the change with time, the tan δ reduction rate (%) of each sample was calculated as “t
an δ reduction rate (%) = ((tan tan −2 immediately after pressing)
Tan δ) after week / tan δ) immediately after pressing × 10
0 ". tanδ reduction rate (%)
(Hereinafter, simply referred to as “decrease rate”) indicates the presence or absence and degree of change with time of each sample. The smaller the value is, the smaller the change with time is, indicating that the damping performance immediately after pressing is maintained. That is, the larger the value of the decrease rate, the more severe the deterioration of the damping performance due to the change over time.

Next, the tan δ measurement result will be described. As shown in Table 2, immediately after pressing, the tan δ of the comparative product (Comparative Samples 2 and 4) was the same as that of the inventive product (Samples 1 to 4).
6) All lower than tan δ. And after pressing 2
T of comparative products (comparative samples 2 and 4) after a lapse of one week
an δ decreases with time, and its tan δ
The reduction rate is greater than the tan δ reduction rate of the product of the present invention (samples 1 to 3), and exceeds 60% in Comparative Sample 4, which is extremely high.

On the other hand, the tan δ of the product of the present invention (samples 1 to 3) immediately after pressing was relatively higher than the tan δ of the comparative product (comparative samples 1 to 6), and two weeks after pressing, The decrease in tan δ due to the change with time is small, and the rate of decrease is extremely small, about several percent or less. Therefore, the tan δ of the product of the present invention (samples 1 to 3) at the time when two weeks have passed after the press also increases. From this,
It can be seen that when a benzotriazole-based additive and a thiazole-based additive or a sulfenamide-based additive are added to the base polymer material, tan δ is increased, and the rate of decrease can be reduced.

As described above, the reason why tan δ is increased is as follows.
This is due to the synergistic effect of blending a plurality of additives. Further, the reduction rate of tan δ was reduced due to the melting point drop phenomenon in the multi-component system.

Next, the product of the present invention and the comparative product, in which the same additives are blended, that is, sample 1 and comparative samples 1 and 2,
Sample 2 and Comparative Samples 2 and 3, Sample 3 and Comparative Samples 2 and 4,
Comparison of tan δ immediately after pressing of Sample 4 and Comparative Samples 2 and 5, Sample 5 and Comparative Samples 3 and 5, and Sample 6 and Comparative Samples 2 and 6 showed that each sample was as shown in FIGS. Is the tan δ immediately after pressing of each comparative sample.
Both are higher than δ. From this, it is understood that when two types of additives are blended in the base polymer material, tan δ can be increased by a synergistic effect. The tan δ of sample 3 and the tan δ of sample 6
And, although there is a slight difference, even if you change the compounding substance,
It can be seen that similar results are shown.

Further, in order to confirm that bleeding and crystallization of the compound components hardly occur due to aging, untreated Sumisorb 250 alone and each sample after aging (Comparative Sample 2, Sample 1 and Sample 2) were used. ) Was subjected to differential scanning calorimetry (DSC). The analysis conditions at this time were as follows: heating rate: 10.0 ° C./min, cell: aluminum cell, gas type: nitrogen, gas flow rate: 50 ml / min.
It is. FIGS. 7 to 9 show the results of the differential scanning calorimetry. In these figures, the horizontal axis represents the environmental temperature, and the vertical axis represents the heating value of the heater.

First, according to FIG. 7 showing the analysis result of the Smithsorb 250 alone, a heat absorption peak recognized as the melting point is observed at around 165 ° C. exceeding 159 ° C.
FIG. 8 shows an analysis result of Comparative Sample 2 (after a change over time) in which Sumisorb 250 was blended with Eraslen 401A.
According to the graph, a slightly broad heat absorption peak is observed in the temperature region substantially the same as that in FIG. According to the results shown in Table 2, it is inferred that Comparative Sample 2 is not so large, but changes with time, and thus is due to crystals formed thereby.

On the other hand, Suncellar D was added to Eraslen 401A.
Sample 1 containing Z and Sumisorb 250 (after aging)
According to FIG. 9 showing the analysis results, it can be seen that slight heat absorption is observed at around 100 ° C., but this is due to the crystals of Eraslen 401A and not due to the additives. Therefore, the obtained results are presumed to be in good agreement with the reduction rates shown in Table 1.

As described above, the product of the present invention (sample 1
-3) were evaluated as very good (marked by ◎) because the tan δ and the tan δ reduction rate (%) were extremely good results. In addition, the product of the present invention (samples 4 to 6)
Although the decrease rate was not measured for, it is assumed that the same result is obtained due to the melting point drop phenomenon in the multi-component system.

The present embodiment has been described above. In short, the chlorinated polyethylene as the base polymer material, in which two kinds of additives are blended, has a high tan δ due to the synergistic effect of blending a plurality of additives. Become
In addition, the change over time is reduced by the melting point drop phenomenon in the multi-component system. Therefore, the high attenuation material composition shown in this example stably expresses high tan δ over a long period of time. Furthermore, since all of the compounded additives have two or three amine compounds selected from secondary amines or tertiary amines in the molecular chain, the attenuation of the compounded material base material is reduced. This contributes to improved performance. According to the present example, it can be seen that this tendency is particularly strong in the benzotriazole-based additive.

In the above embodiment, the base polymer 100
Although two types of additives are blended by 50% by weight per weight%, the present invention is not limited to this, and three or more types of additives may be blended.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the above embodiment,
Chlorinated polyethylene was used as the base polymer material, but instead of this, natural rubber, modified natural rubber, grafted natural rubber, cyclized natural rubber, chlorinated natural rubber, styrene-butadiene rubber, chloroprene rubber, acrylonitrile-butadiene were used.

In the above embodiment, N, N-dicyclohexylbenzothiazyl-2-sulfenamide or N-oxydiethylenebenzothiazyl-2-sulfenamide was used as the sulfenamide-based additive. However, a material such as N-cyclohexylbenzothiazyl-2-sulfenamide or N-tert-butylbenzothiazyl-2-sulfenamide may be used instead. Further, in the above embodiment, tetraethylthiuram disulfide was used as the thiazole-based additive, but a material such as tetrabutylthiuram disulfide may be used instead.

[0040]

The high damping material composition of the present invention is obtained by blending a base polymer material having a polar side chain with a benzotriazole-based additive and a sulfenamide-based or thiazole-based additive. The tan δ increases due to the synergistic effect of these plural additives, and the reduction rate of tan δ decreases due to the melting point drop phenomenon in the multi-component system. Therefore, according to the high damping material composition of the present invention, the loss tangent (tan δ) is higher than that of the related art.
The characteristics are realized, and the deterioration of the damping performance due to the change over time is suppressed. This makes it possible to maintain high and stable damping performance over a long period of time. Such a high damping material composition, such as building structures and vehicles,
