HEAT RESISTANT NATURAL RESIN SUBSTRATE AND METHOD OF PRODUCING HEAT RESISTANT NATURAL RESIN SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a heat resistant natural resin substrate which overcomes functional defects of heat resistance, shock resistance, hydrolytic resistance, moldability, etc. of natural resins aiming the carbon neutral in the place of fossil resources, thereby, can be produced by a simple production method while using only natural material as raw material, can obtain heat resistance and heat expansion resistance of 250°C or more, can suppress warping in high temperature environment and has light weight and strength, and to provide a method of producing the heat resistant natural resin substrate.;SOLUTION: The heat resistant natural resin substrate is a laminate composed of: a core material and a reinforcing material which are made of natural rubber containing a fabric formed from natural fiber and glass fine hollow spherical bodies; and a surface layer material made of ebonite containing glass fine hollow spherical bodies. The heat resistant natural resin substrate has functions of insulation property, weather resistance, acid resistance, alkali resistance and mechanical strength of ebonite, of light-weight property, heat resistance and heat expansion resistance of the glass fine hollow spherical bodies and of light-weight property, strength and shock resistance of the natural fiber. The heat resistant natural resin substrate is excellent in heat resistance and heat expansion resistance and hardly causes warping in high temperature environment. The method of producing heat resistant natural resin substrate is also provided.;COPYRIGHT: (C)2012,JPO&INPIT
