Abstract

This invention is concerning a structure body containing inorganic particles having an average particle diameter of 6 mm to 50 mm, and 6 parts by mass to 40 parts by mass of a resin with respect to 100 parts by mass of the inorganic particles.

First claim

1 . A structure body containing inorganic particles having an average particle diameter of 6 mm to 50 mm, and 6 parts by mass to 40 parts by mass of a resin with respect to 100 parts by mass of the inorganic particles.

2 . The structure body according to claim 1 ,
wherein the structure body has a plurality of continuous gaps therein which allows one end surface to communicate with the other end surface.

3 . The structure body according to claim 1 ,
wherein bulk specific gravity is less than or equal to 0.9.

4 . The structure body according to claim 1 ,
wherein an average particle diameter of the inorganic particles is 6 mm to 20 mm, and 70 mass % or more of the inorganic particle has an average particle diameter of 6 mm to 20 mm.

5 . The structure body according to claim 1 ,
wherein the inorganic particles are one or more types of particles selected from the group consisting of natural stone, silica sand, obsidian, pearl stone, Kohga stone, white sand, shale, glass, zeolite, ceramic and a fired foamed body thereof, perlite, pumice stone, scoria, a hollow balloon, and a lightweight aggregate.

6 . The structure body according to claim 1 ,
wherein the resin is formed by curing a resin composition which contains a thermosetting resin having a viscosity of 0.08 Pa·s to 2 Pa·s, a curing agent, and a curing accelerator.

7 . The structure body according to claim 6 ,
wherein the thermosetting resin is one or more types of resins selected from a group consisting of an unsaturated polyester resin, a vinyl ester resin, a phenol resin, a urea resin, a melamine resin, and an epoxy resin.

8 . A sound absorbing material formed of the structure body according to claim 1 .

9 . A sound insulating wall material formed of the sound absorbing material according to claim 8 .

10 . A manufacturing method of a structure body, comprising:
a step of mixing inorganic particles having an average particle diameter of 6 mm to 50 mm, and 6 parts by mass to 40 parts by mass of a resin composition with respect to 100 parts by mass of the inorganic particles; and a step of molding the mixed inorganic particles and resin composition without pressuring.
