Manufacturing method of woody base material, cosmetic material and wood base material

摘要

Problem to be solved: to provide a manufacturing method of a wood base material, a cosmetic material and a wood base material having practical mechanical strength and water resistance.Powdered or chipped wood material 11A wood base material 20 formed by heating and pressurizing a raw material mixture containing a powdery thermoplastic resin composition 12Thermoplastic resin composition 12Thermoplastic resinOrganic peroxidesAn acid containing resin containing at least one carboxylic acid or carboxylic anhydride andAndOrganic peroxide contentFor 100 parts by weight of thermoplastic resinIt is 0.01 to 3 parts by mass;The content of acid containing resin isFor 100 parts by weight of thermoplastic resin1 to 50 parts by mass.Also, the mass ratio (wood material / thermoplastic resin composition) of the wood material 11 and the thermoplastic resin composition 12 in the raw material mixture 10 may be 95 / 5 to 70 / 30, or the acid containing resin is maleic anhydride modified polyolefin or ethylene (meta) An acrylic acid copolymer may be used.Diagram
