Abstract

<P>PROBLEM TO BE SOLVED: To provide a building material produced by integrating a surface layer (outside) material having low water absorption, flame retardancy, fireproof property and durability with an inside layer material having hygroscopicity and properties of heat insulation, sound absorption and fireproof. <P>SOLUTION: This building material is produced by charging, in a frame, a material prepared by blending and kneading a silica particulate which is an unused resource, crushed stone powder, cement and a particular admixture as a main component of the surface layer material and after leveling the material surface, charging thereon a kneaded material formed by adding a small amount of water to waste paper, shirasu, pumice, cement and an admixture mineral, leveling and then forming. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

[0101]
TECHNICAL FIELD OF THE INVENTION
The object of the present invention is to manufacture a building material that is manufactured separately from a surface material and an inner layer material, and is integrated with the current building material used.
[0092]
[Prior art]
Conventionally used building materials have the following performance and characteristics.
Surface material: Flame retardant, fire resistant, low water absorption, durable, etc.
Inner layer material --- It is a necessary condition to have moisture absorption, heat insulation, sound absorption, fire protection, etc.
However, the characteristics and characteristics of the individual were selected and combined to add the materials and labor as one. Such waste should of course be improved.
[0093]
[Problems to be solved by the invention]
The method to be solved by the present invention is as follows.
{Circle around (1)} Japanese Patent Application No. 2002-382647, that is, the use of silica powder, crushed stone powder and cement, which are fine particles of unused resources as the main constituent material of the surface layer, and the mixing and kneading of special admixtures. {2} Japanese Patent Application No. 2000-132968. Publication No. 2001-270771, ie, use of multifunctional interior building materials using waste paper. (3) Japanese Patent Application No. 2002-183683, ie, use of concrete using shirasu.
[Means for Solving the Problems]
(1) described in the above (1) is a method for preparing and kneading a surface material, and (2) and (3) are methods for preparing and kneading an inner layer material. Therefore, the surface material of (1) differs from the inner layer material of (2) and (3) in performance and characteristics. As a manufacturing procedure, (1) is poured, and then (2) or (3) is continuously applied, and then molded to be smooth and uniform.
[0056]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described.
(1) A kneading material that is fluidized by adding a mixture of finely divided silica stone or crushed stone powder, cement, and an admixture, which is a constituent material of the surface layer material, into a mixer and adding an appropriate amount of natural water. Is poured into a molding form and evenly smoothed with a vibrator.
(2) A blended material containing the used recycled paper, shirasu, pumice, cement, and admixture, which is a constituent material of the inner layer material, is charged into a mixer, and an appropriate amount of natural water is added thereto, and the mixture is fluidized continuously. The work is leveled uniformly on the smooth surface of (1) to a specified thickness.
[0086]
【The invention's effect】
The product of the present invention can be expected to have multifunctionality such as heat insulation, sound absorption, moisture absorption and release by integrating the inner layer material as well as the material for rain and wind, such as corrugated iron and slate.
Especially, the use of waste paper makes the interior moisture absorbing and desorbing wood. Outstanding effects have been demonstrated compared to veneer and fireproof boards. In the fire resistance test using waste paper, there was no emission of gas or smoke even in the first-grade flame retardant test, and the backside temperature after 15 minutes was 760 ° C and the heat insulation property was good at 42 ° C.
[Brief description of the drawings]
FIG. 1 is a perspective view of the present invention. FIG. 2 is a sectional view of A.
1 ------ Surface material 2 ----- Inner layer material

Claims (1)

(1) Surface material kneaded with fine silica powder or crushed stone powder, cement and special admixture. (2) Inner layer material (1) kneaded with waste paper, shirasu, pumice, cement and special admixture melted with water. The surface material is smoothly poured into the mold, and the inner layer material of (2) is continuously charged into the mold and smoothed and molded.
