Problems solved by technology

Its other disadvantages are that it does not show high maximum loss modulus (E") and loss factor (η) at high temperature, and the useful temperature range is narrowed, because the interaction is easily destroyed at high temperature
These disadvantages hamper its industrial application

Embodiment 1-7

[0080] Vibration damping material compositions were prepared in each of Examples 1-7 in which 100 parts of acrylic rubber as the organic polymer binder material were combined with different poly-4-vinylphenol resins as damping agents given in Table 1 (Poly-p-vinylphenol resin) ("Marukalyncur-M" series of Maruzen Petrochemical) mixed, and the amount of vibration damping agent is also given in Table 1. Each mixture is at 180°C and 200kgf / cm 2 Under hot pressing, a sheet-like vibration damping material composition with a thickness of 1 mm was formed. The evaluation results are given in Table 1.

Embodiment 8 and 9

[0082] Vibration damping material compositions were prepared in each of Examples 8 and 9 in which a 50 / 50 mixture of polylactic acid resin and polybutene succinate with different poly-4-ethylene as damping agents given in Table 1 phenol resin ("Marukalyncur-M" series of Maruzen Petrochemical) was mixed, and the amount of vibration damping agent is also given in Table 1. Each mixture is at 180°C and 200kgf / cm 2 Under hot pressing, a sheet-like vibration damping material composition with a thickness of 1 mm was formed.

Embodiment 11-14

[0097] In each of Examples 11-14, a vibration damping material composition was prepared in which a mixture of acrylic rubber and polypropylene in the ratios given in Table 3 was mixed with poly-4-vinyl as a vibration damping agent given in Table 3. Phenol resin was mixed, and the amount of damping agent was also given in Table 3. Each mixture is at 140-180°C and 100-200kgf / cm 2 Under hot pressing for 20 minutes, a sheet-like vibration damping material composition was formed.

[0098] The vibration damping performance was determined by measuring the temperature region in which each sheet-like composition could maintain its dissipation factor (?) at 0.08 or more by the aforementioned method. The evaluation results are given in Table 3.

Abstract

It is an object of the present invention to provide a vibration-damping composition having a high loss modulus (E'') and loss factor (eta) in a high temperature region, and serviceable over a wide temperature range in a high temperature region. Provided is a (1) vibration-damping composition whose matrix material of organic polymer contains a vibration-damping agent, or (2) vibration-damping composition whose matrix material of organic polymer contains a vibration-damping agent, and inorganic and / or organic filler, wherein the vibration-damping agent is of a polyvinyl phenol-based resin having a recurring unit represented by the general formula [I].

Description

technical field [0001] The present invention relates to a vibration damping material composition, more particularly a vibration damping material composition capable of damping vibration and sound, which is used as a raw material (or in a coating or other form), especially as a sheet-like product for automobiles , buildings, various industrial equipment, household appliances and medical equipment, especially as a vibration damping agent for the above purposes. Background technique [0002] In today's industrialized society, due to the increasing need to save energy and reduce environmental loads to protect the global environment, there is a great need for lighter vibration and sound insulation materials. [0003] However, traditional polymer-based vibration-damping materials with vibration-damping and sound-insulating functions rely on the respective viscous and frictional effects provided by various viscoelastic and inorganic filler components they contain, by converting ext...
