  • Method of producing wood fiber type composite material product having high rigidity and high heat deformation temperature characteristics
    Patent number: 6066278
    Abstract: A method for producing a composite material product which has a high rigidity and a high heat deformation temperature and is mainly composed of a wood cellulose filler and olefin series plastic. Calcium oxide is added to a mixture of a wood cellulose filler crushed into a predetermined size, a granular olefin series plastic material and a rigidity improving agent mainly consisting of polypropylene modified by maleic anhydride or its derivative. An amount of calcium oxide to be added is calculated so that water of the wood cellulose filler becomes finally 2-5% (percent weight). A compound produced by mixing the mixture and calcium oxide is then molded by a molding machine. The polypropylene modified by maleic anhydride has a high degree of modification by maleic anhydride and a small molecular weight.
