Abstract

PURPOSE:To provide the titled compsn. giving a restraining layer having excellent flow characteristics and thixotropic properties without deteriorating vibration damping properties, by blending an inorg. filler and a plasticizer with a resin mixture of rosin and a specified acid-modified diene polymer. CONSTITUTION:A rosin (A) such as rosin or its ester is mixed with an acid- modified diene polymer (B) obtd. by modifying a conjugated diene polymer having an arom. vinyl monomer content of 5-60wt% (e.g. a styrene/butadiene copolymer) with an ethylenically unsaturated carboxylic acid (anhydride) (e.g. acrylic acid or maleic anhydride), in such a proportion that component B accounts for 20-95wt% of the mixture. An onorg. filler (e.g. silica or calcium carbonate) or a plasticizer (e.g. dibutyl phthalate or linseed oil) are blended with the resulting resin mixture to obtain the desired compsn. for a restraining layer of a vibration damping sheet.

[Detailed Description of the Invention] Technical Field> The present invention relates to a composition for a restraining layer in a vibration damping sheet that is attached to a vibrating metal substrate such as a vehicle floor surface to attenuate vibrations, Background technology related to resin-like materials blended with inorganic fillers and plasticizers> In order to obtain a large vibration damping force, the material for the restraining layer in a vibration damping sheet must not only have high rigidity but also an adhesive layer. It is desired that the material has good adhesion to the material, and from the viewpoint of workability, it is also desired that the material exhibits good fluidity when heated and melted. Furthermore, the damping sheet is often subjected to impact from flying stones etc. through the vehicle floor surface while driving on rough roads, and is therefore required to have impact resistance. Note that if the restraint layer has poor impact resistance and cracks form, the vibration damping properties will be significantly reduced.

In order to meet the requirements mentioned in 2 above, in a patent application filed by the same person as the applicant (Japanese Patent Application No. 170109/1982, filed on September 15, 1988), petroleum resin was used as a material for the constraining layer. Products containing inorganic fillers and plasticizers have been proposed. When a restraining layer is formed using this material, it has a large vibration damping force11) and excellent impact resistance.
Although it contains plasticizers, the material does not have sufficient fluidity when melted and has low chicken tropism, so the workability during mixing and application was not necessarily good. If a large amount of Of plastics is added to obtain sufficient fluidity, the above-mentioned problems can be solved to some extent, but on the other hand, the rigidity of the constrained layer, that is, the damping force, is undesirably reduced.

(A) As a resinous material, add 20 to 95% of the following acid-modified diene polymers (hereinafter referred to as "acid-modified polymers") to rosin.
A mixture is used so that the weight ratio is %. Note that since rosin is a natural product and is expensive, it is desirable that the amount of acid-modified polymers mixed is half or more. If the mixing amount is outside the above range, the resin material itself will not have sufficient strength and will not exhibit good chicken tropism, which is a measure of workability. In addition, if the mixing amount is less than 20 wt%, the thermal stability of the resin itself (rosin has poor thermal stability) cannot be obtained sufficiently (1) As for rosin, use one with a softening point of 60 to 140°C. Available rosin, rosin ester, hydrogenated rosin ester,
Examples include rosin derivatives such as maleated rosin, polymerized rosin, disproportionated rosin, phenol-modified rosin, and maleated rosin glycerin ester.

■If the content of the aromatic vinyl monomer in the conjugated diene copolymer is outside the above range, the above-mentioned blending effects of the acid-modified polymers □ material strength and chicken tropism □ cannot be obtained. Examples of the conjugated diene used in this conjugated diene copolymer include 1,3-pentadiene, isoprene, and butadiene, but 1,3-pentadiene is preferred from the viewpoint of compatibility with rosins. Examples of the aromatic vinyl monomer include styrene, α-methylstyrene, vinyltoluene, impropenyltoluene, etc., but di-α-methylstyrene is preferred. In addition, this conjugated diene copolymer may use other cyclopentene, butene, pentene, pinene, etc. as a comonomer. It is particularly desirable to use cyclopentene because it improves compatibility with rosins.

.. Inorganic foams such as glass balloons, glass balloons, and foamed stones can also be used. When this inorganic foam is used, the weight of the constraint layer can be reduced. This inorganic filler increases the rigidity of the restraining layer and increases the damping force.Although the reason is unknown, inorganic fillers generally tend to reduce the impact resistance of the polymer. Improves the impact resistance of objects. The blending amount of the inorganic filler is determined from the viewpoint of achieving these effects and workability.
