振材を挾装して積層される拘束材に関する。Detailed Description of the Invention (Industrial Field of Application) The present invention provides a vibration damping method for forming a sandwich-type vibration damping structure on a vibrating base material that easily vibrates, such as a vehicle floorboard or an instrument panel. It relates to a restraining material that is stacked by sandwiching materials.

いう問題がある。In addition, in recent years, a metal sheet such as steel or aluminum is provided as a restraining material on the top surface of asphalt-based vibration damping material, or a sandwich structure is created by laminating thermosetting resin such as epoxy resin, diallyl phthalate resin, or acrylic resin. Efforts are also being made to improve vibration damping performance. (For example, JP-A-58-63542, JP-A-62
-19445, etc.) (Problems to be Solved by the Invention) However, these vibration damping structures have the following problems. In other words, in a double-layer damping structure in which the vibration of a vibrating base material is damped using only a heat-adhesive damping sheet mainly composed of asphalt, the thickness must be increased in order to improve its damping performance. , which increases vehicle weight and costs. In addition, in the case of a sandwich-type damping structure in which a steel plate, aluminum plate, etc. is laminated on the top surface of an asphalt-based heat-adhesive damping sheet, the damping performance as a structure is improved, but the restraining layer is made of a highly rigid metal. In order to adhere the plate to the heat-adhesive damping sheet, it is necessary to fix it mechanically to a highly rigid vibration base material such as a steel plate, or by screwing it with bolts, etc. There is. However, since the floorboards of vehicles are generally press-formed into an uneven shape for the purpose of imparting rigidity, it is necessary to form the restraining metal plate into a complementary shape, which requires an extra process. Another problem is that it is not easy to correctly position the device at a predetermined position during installation.
また、未硬化の熱硬化性樹脂を制振層上に載置し塗装す

不都合はないものの、未硬化の熱硬化性樹脂自身が保存

際して反応が早すぎると床板等の凹凸形状に追従できな
かったり制振層との融着不良を生ずるなどの欠陥を生じ
、制振特性を損なうなどの問題もあった。In addition, although the method of placing an uncured thermosetting resin on the damping layer and curing it during the painting process and using it as a restraining layer does not have the above disadvantages, the uncured thermosetting resin itself is stored during storage. There is a problem that it cannot be stored for a long time when the temperature is high due to the curing reaction occurring.Furthermore, if the curing reaction is too fast, it may not be able to follow the uneven shape of the floorboard, etc., or it may become fused with the vibration damping layer. There were also problems such as defects such as defects and loss of vibration damping characteristics.
（問題点を解決するための手段）
本発明はこのような問題点を改良したものであって、車

から形成することにより満したものである。Here, the restraining material of the present invention has a high elastic modulus, is excellent in durability, is lightweight, and is required for use in this type of vehicle to completely adhere to the uneven vibrating base material by heat treatment during the painting process etc. In addition, preferred properties include a small decrease in elastic modulus even at relatively high temperatures and good workability. The restraining material according to the present invention satisfies these requirements by being formed from a composition in which at least one of an elastomeric material, a plasticizer, and glass fiber is blended with a tackifying resin. .

Polyterpene resins such as pinene polymers, modified terpenes such as terpene phenols, cyclopentadiene resins, aromatic petroleum resins, alkylphenol-acetylene resins, xylene resins, coumaron indene resins, vinyltoluene-α-methylstyrene copolymer It is a resin-like tackifier such as a resin and has a softening point of at least 60°C or higher. These tackifier resins can be used alone or in combination of two or more.
これらの粘着付与樹脂の軟化点は６０℃〜１８０℃であ
るのがよく、更に好ましくは８０℃〜１４０℃である。The softening point of these tackifying resins is preferably 60°C to 180°C, more preferably 80°C to 140°C.

分程度の条件となる塗料焼付工程を利用して行なわれる
が、６０℃未満の軟化点のものでは不均一な流動を生じ
て均質な厚さの拘束構造が得られなくなる。If the temperature is less than 60° C., the temperature range in which it functions as a restraining material for the sandwich-type vibration damping structure of a vehicle is narrow, resulting in the disadvantage that flow occurs even within the actual operating temperature range of the vehicle. Furthermore, the process of installing vibration damping materials on vehicles is usually carried out at 120°C to 150°C and 30°C.
This is carried out using a paint baking process that requires about 10 minutes, but if the softening point is less than 60°C, non-uniform flow will occur, making it impossible to obtain a constrained structure with a uniform thickness.
また逆に、１８０℃以上であれば塗料焼付工程の条件で
は制振材との融着が不充分になるとともに鋼板の凹凸に
対して追従しなくなり、良好な割振特性が得られなくな
るばかりでなく外観も極めて悪くなる。On the other hand, if it is above 180°C, under the conditions of the paint baking process, the fusion with the damping material will not be sufficient and it will not follow the unevenness of the steel plate, which will not only make it impossible to obtain good vibration distribution characteristics. The appearance will also be extremely poor.

The blending amount of these elastomer materials is
Although it depends on the amount of other compounding agents used, the amount is 100 parts by weight or less, preferably 5 to 50 parts by weight, per 100 parts by weight of the tackifying resin. If it exceeds 100 parts by weight, not only will it be extremely difficult to mix with the resin, but the elastic modulus of the molded product will decrease and it will no longer function as a restraining material in a sandwich-type vibration damping structure.

能を果たさなくなるから好ましくない。Therefore, the type is not limited as long as it has a certain level of compatibility with the tackifying resin. These plasticizers include dimethyl phthalate, dibutyl phthalate,
Phthalic acid derivatives such as di(2ethylhexyl)phthalate and other higher alcohol phthalates; isophthalic acid derivatives such as dimethylisophthalate and di(2ethylhexyl)isophthalate; tetrahydrophthalate such as di(2ethylhexyl)tetrahydrophthalate and diisodecyltetrahydrophthalate; Acid derivatives, adipic acid derivatives such as di(2-ethylhexyl) adipate, diisodecyl adipate, diisononyl adipate, Ki sebacic acid derivatives such as dibutyl phthalate, di(2-ethylhexyl) sebacate, tri(2-ethylhexyl) trimellitate,
Examples include trimellitic acid derivatives such as triisodecyl trimellitate, monoester derivatives of organic acids such as citric acid, itaconic acid, and oleic acid, paraffin derivatives, epoxy derivatives, and polyester polymerization type plasticizers. In addition, other mineral oil softeners such as paraffinic process oil, naphthenic process oil, aromatic process oil, vegetable oil softeners such as castor oil, cottonseed oil, linseed oil, rapeseed oil, soybean oil, palm oil, coconut oil, etc. etc. can also be used. The amount of these compounds depends on the characteristics of the tackifying resin and the amounts of other compounding agents used, as well as the expected processing properties of the resulting composition and the properties of the plasticizer.
The amount is 50 parts by weight or less, preferably 5 to 25 parts by weight. If it exceeds 50 parts by weight, the modulus of elasticity of the molded product will decrease and it will no longer function as a restraining material in a sandwich-type vibration damping structure, which is not preferable.

Chopped strand fibers of less than 25111 mm are used, preferably less than 25111 mm. Even if fibers with a length of 100 mm or less are used, not only no improvement in strength is observed, but also many fibers break during mixing.
This is because it may be difficult to obtain a uniformly dispersed state. The amount used depends on the amount of other compounding agents used, but is 75 parts by weight or less, preferably 5 to 50 parts by weight, based on 100 parts by weight of the tackifying resin. If it exceeds 75 parts by weight, processing becomes difficult, which is not preferable.

ることもできる。The method of molding the restraining material according to the present invention is not particularly limited, but for example, the above-mentioned tackifying resin and a predetermined compounding agent are heated and mixed with various mixers such as a Banbury mixer, Henschel mixer, ribbon blender, etc., and extrusion molding, It may be formed into a sheet by roll molding, injection molding, press molding, or the like. As a special molding method, a sheet-like molded product can also be obtained by melting and mixing the components in a container that can be heated and mixed, and then flowing and dripping the molten composition through a slit-shaped nozzle or the like. In order to prevent inconveniences such as cutting of glass fibers and destruction of micro hollow bodies during processing, it is preferable to select a mixing method that does not apply such large shearing forces. Tackifying resins have a significantly lower melt viscosity than ordinary resins such as polyethylene, polypropylene, and polyvinyl chloride, or rubbers such as butadiene rubber, styrene/butadiene rubber, and acrylonitrile/butadiene rubber, so they cannot be extruded or kander molded. Even without using a molding method that involves strong shearing force, the ingredients can be easily dispersed homogeneously by simple heating and melting and mixing, and a sheet can also be obtained by directly flowing out from a slit-shaped nozzle.

する等の特徴を有するものである。(Effects of the Invention) As explained above, the restraint material according to the present invention is placed on a vibrating base material such as a wheel together with a heat-fused vibration damping material, and in a painting process etc. By heating the damping material and the restraining material at the same time, they can be tightly fixed, so there is no increase in the number of steps that would be required when using a metal plate as the restraining material. Because it does not utilize curing through cross-linking reactions, etc., it can withstand long-term storage without any change in curing performance over time, unlike constraining materials containing thermosetting resins, and is also easy to control during the heat fusion process. There is no defective fusion with the vibrating material or poor tracking of the uneven shape of the vibrating base material, and the resulting sandwich-type vibration damping structure exhibits excellent damping effects over a wide temperature range. It is.
