Embodiment 1

[0159] Put 80.0 parts of castor oil polyol URIC H-102 (manufactured by Ito Oil Co., Ltd.) and 20.0 parts of Riken resin LA-15-100 (manufactured by Miki Riken Industry Co., Ltd.) into the container so as not to damage the microcapsule shell. Method Use a high-speed disperser to disperse for 10 minutes at a speed of 500 rpm or less. Then, 0.2 parts of Toray Dow Corning SAG-47 (manufactured by Toray Dow Corning Co., Ltd.), 3.0 parts of molecular sieve 4A powder (manufactured by Union Showa Co., Ltd.), and 0.1 part of 10% GLECK TL (manufactured by DIC Corporation) were sequentially added Afterwards, stir and prepare the main agent. Next, 70.1 parts of MILLIONATE MTL (manufactured by Nippon Polyurethane Industry Co., Ltd.) was added as a curing agent under the condition of NCO / OH=1.06 with respect to the main ingredient, mixed and then defoamed to prepare a urethane resin composition.

[0160] The defoamed urethane resin composition was poured into a molding frame of 100×100×25 mm...

Embodiment 2～17、 comparative example 1～7

[0162] Except changing the kind and usage amount of raw materials as shown in Table 2 or Table 4, prepare the urethane resin composition in the same manner as in Example 1, except using the obtained composition, follow the same method as in Example 1 A urethane resin molded body was obtained in a manner. In addition, details of each material in Table 2 or Table 4 are shown in Table 1.

Embodiment 18

[0164] 80.0 parts of castor oil-based polyol URIC H-81 (Ito Oil Co., Ltd.) and 15.0 parts of Exolit AP462 (manufactured by Clariant) were put into a container, and dispersed at 1000 rpm for 15 minutes with a high-speed disperser. Then, 20.0 parts of Riken Resin LA-15-100 (manufactured by Miki Riken Industry Co., Ltd.) was blended, and the microcapsule shells were not damaged by dispersing with a high-speed disperser at a rotation speed of 500 rpm or less for 10 minutes. After the dispersion process, 0.3 parts of Toray Dow Corning SAG-47 (manufactured by Toray Dow Corning Co., Ltd.), 3.0 parts of molecular sieve 4A powder (manufactured by UNION Showa Co., Ltd.), and 0.1 part of 10% GLECK TL (manufactured by DIC Corporation) were added in sequence. manufactured by the company) and then stirred to prepare the main ingredient. Next, 74.5 parts of MILLIONATE MTL (manufactured by Nippon Polyurethane Industry Co., Ltd.) was added as a curing agent under the condition of NCO / OH=1.06 w...

Abstract

The present invention relates to a vibration-damping urethane resin composition, a vibration-damping molded urethane resin object, and a method for forming the molded object, the vibration-damping urethane resin composition comprising a castor-oil-derived polyol (A), an isocyanate (B), and inorganic particles (C) which contain a phase-change substance therein.

Description

technical field [0001] The present invention relates to a vibration-damping urethane resin composition, a vibration-damping urethane resin molded article, and a method for forming the molded article. Background technique [0002] At present, in order to achieve the correct and simple installation of equipment in the lower part of the ship engine, a filling material with excellent resistance to load and heat resistance is used, but this filling material does not have vibration damping properties, so there is a risk of Risk of engine component damage. Then, in order to prevent the vibration of the engine from being transmitted to the engine parts, a damping material suitable for the lower part of the ship engine has been studied. [0003] On the other hand, as a vibration-damping material, a rubber-like flexible material, a vibration-damping urethane resin composition, or the like is generally used. [0004] As such a damping material, for example, Patent Document 1 describe...
