Abstract

A manufacturing method for providing a cement bonded wood chip product, a resin bonded wood chip product and a simulated wood product, in which recycled wooden members and recycled resinous members are pulverized after having been mixed. Accordingly, a mixing process and a pulverizing process can be integrated into one single line, reducing the space as well as laborious work and efficient operation in a plant.

A manufacturing method of a simulated wood product utilizing pulverized powders obtained from recycled building members as raw material, in which the building members comprise recycled wooden members made of wooden materials and resinous members made of resinous materials, the manufacturing method further comprising a mixing process for mixing the recycled wooden members, a pulverization process for pulverizing the mixed materials obtained in the mixing process to form pulverized powder, a kneading process for kneading the pulverized powders obtained by the pulverizing process, and a molding process for molding the kneaded materials obtained in the kneading process either by an extrusion or injection molding.

Claims

1. A manufacturing method of a simulated wood product utilizing pulverized powders obtained from recycled building members as raw material, said building members containing recycled wooden members made of wooden materials and recycled resinous members made of resinous materials, said method comprising the steps of;

mixing said recycled wooden members and said recycled resinous members;

pulverizing a mixture obtained in the mixing step for producing pulverized powders;

kneading the pulverized powders obtained in the pulverizing step; and

molding the kneaded materials obtained in the kneading step by either extrusion or injection molding.

2. A manufacturing method of a simulated wood product according to

claim 1

, wherein dispensing amount of recycled wooden members and recycled resinous members in the mixing process is determined by the number of times for which respective members are filled in and dispensed by a dispensing vessel of a predetermined volume.

3. A simulated wood product molded by either extrusion or injection molding, the simulated wood product comprising pulverized powders obtained from recycled building members, wherein said building members include recycled wooden members made of wooden materials and recycled resinous members made of wooden materials, and wherein said pulverized powders include recycled wooden members and recycled resinous members in a mixed state by mixing and pulverizing the recycled wooden members and recycled resinous members together.

4. A simulated wood product molded by either extrusion or injection molding, the simulated wood product comprising pulverized powders obtained from recycled building members,

wherein impalpable powders smaller in size and harder than the pulverized powders to produce fixed particles are affixed onto the outer circumferential surfaces of said pulverized powders,

wherein a resin and a pigment are mixed with the fixed particles and a resultant mixture is molded into a simulated wood product by either extrusion or injection molding to exhibit a pattern similar to the grain of natural wood,

wherein said building members include recycled wooden members made of wooden materials and recycled resinous members made of wooden materials, and

wherein said pulverized powders include recycled wooden members and recycled resinous members in a mixed state by mixing and pulverizing the recycled wooden members and recycled resinous members together.

5. A cement bonded wood chip product molded by compression molding, the cement bonded wood chip product comprising a mixture of pulverized powders obtained from recycled building members and cement,

wherein said building members include recycled wooden members made of wooden materials and recycled resinous members made of resinous materials, and

wherein said pulverized powders include recycled wooden members and recycled resinous members in a mixed state by mixing and grinding the recycled wooden members and recycled resinous members together.

6. A resin bonded wood chip product comprising pulverized powders obtained by pulverizing recycled building members and adhesive,

wherein said pulverized powders is mixed with the adhesive and a resultant mixture is molded by thermocompression molding,

wherein said building members include recycled wooden members made of wooden materials and recycled resinous members made of resinous materials, and

wherein said pulverized powder include recycled wooden members and recycled resinous members in a mixed state by mixing and grinding together the recycled wooden members and recycled resinous members.
