Provided is a material having an excellent sound-absorbing performance which can be easily applied to the desired area at the operation site and which can effectively prevent sound leakage. The material includes an open-cell soft polyurethane foam prepared from a 2-part reactive urethane resin composition prepared from a polyisocyanate component and a polyol-containing component,

2-part reactive urethane resin composition and method for producing thereof

The present invention is to provide a composition which can easily form a polyurethane resin which exerts particularly excellent damping properties in an operating temperature range. A resin composition for damping materials, including a polyol-containing component (A) and a polyisocyanate (B) is provided. The polyol-containing component (A) contains a castor oil. When the composition is cured, the peak on its Tan &#x3b4; curve is 0.7 or more and the temperature for the peak is in a range of &#x2212;10&#xb0; C. to 100&#xb0; C.

Resin composition for damping materials

A method of manufacturing a polyurethane resin moulding for a vehicle interior part, includes: adding at least one of a polyol mixture and a polyisocyanate compound to at least one of microencapsulated paraffin waxes and shirasu balloons, followed by polymerizing the polyol mixture and the polyisocyanate compound. The polyol mixture contains a polyol, a catalyst, a chain extender and an auxiliary agent. A melting point of the microencapsulated paraffin waxes is 60&#xb0; C. to 80&#xb0; C.

Polyurethane resin moulding for vehicle interior part and method of manufacturing the same

The present invention provides an integral skin molded article used for vehicle internal parts, which enables good production efficiency and cost reduction and has good external appearance, and a method of preparing an integral skin molded article, and also provides a laminate with a skin comprising the integral skin molded article and a core material, and a method of preparing a laminate with a skin. Disclosed are an integral skin molded article obtained by injecting a polyurethane foam for a skin into a die after injecting a high density polyurethane resin for a core, containing a high density polyurethane resin for a skin, containing a polyol component, 1-methyl-3,5-diethyl-2,4-diaminobenzene and/or 1-methyl-3,5-diethyl-2,6-diaminobenzene, and a blowing agent into the same die; and a method of preparing a laminate with a skin comprising a skin molded article and a core material.
