Abstract

<P>PROBLEM TO BE SOLVED: To overcome the problem such that a lath earth wall system is difficult to construct due to the shortage of lath leveling professionals, necessity of a lot of steps such as rough coating and middle coating, and further difficulty of the acquisition of an earth wall material that is the raw material although it is excellent in capability of controlling an indoor temperature/humidity problem that is a demerit of the humid climate of Japan and further has fire-resisting and sound-insulating functions, whereas a recent inner wall for Japanese house is frequently constructed by a pasting system of an easy interior mateiral such as cloth which is inferior in humidity conditioning function, without using the lath earth wall system which was frequently used in the past. <P>SOLUTION: An Oku-Noto diatomite wall material is applied to a wall surface instead of an interior material such as cloth, whereby an inner wall excellent in properties of lath earth wall is created. The Oku-Noto diatomite wall material is composed of: sintered powder of Oku-Noto diatomite wall earth as main component (about 41%); a mixed material of silica sand, natural pumice and pearlite as aggregate (about 31%); plaster as hardener (about 25.5%); slaked lime (about 0.5%) and citric acid (about 0.5%) as coagulation retarder; methylcellulose (about 0.1%) as thickener/moisturizing agent; benzimidazol-based agent (about 0.1%) as midewcide; and hemp (1.3%) as crack preventing material. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to an Okunoto diatomaceous earth wall material on a wall of a wooden house, for example.

  Many wooden masonry walls were seen on the walls of Japanese wooden houses. This wooden masonry wall was adapted to the humid Japanese climate and served to control the indoor temperature and humidity. Furthermore, it had soundproofing and fireproofing functions.

  As the structure of the earth wall, a through-hole is provided in the pillar as a wall structure, a wooden dance is scratched between the through-holes, and as a plastering work, the process of rough coating → back coating → penetration → intermediate coating → (sometimes top coating) It will be completed after that.

  In this way, the conventional earthen wall requires the work of wooden dance, and recently there are fewer craftsmen of this wooden dance. In addition, since a large amount of soil is used, it has become difficult to obtain the soil itself. It became difficult to build houses using earthen walls for reasons such as these.

  Recently, a method of using a heat insulating material such as glass wool as a wall surface structure, attaching a plaster board or the like, and attaching an interior material such as a cloth with an adhesive has become common. In such a method, the house becomes airtight, moisture-related problems such as condensation that did not become a problem in the Kimai wall house, and the problem of irritating odor due to the influence of interior materials, furniture, daily necessities, etc. There are also problems of suffocation due to incomplete combustion in the event of a fire due to a decrease in fire prevention capacity due to the diversification of petroleum products such as cloth.

  The present invention uses a heat insulating material such as glass wool, attaches a plaster board, etc., and has problems with moisture / soundproofing and fireproofing, which are disadvantages of a house having an inner wall such as a cloth or other interior material attached with an adhesive. -It is an object to provide a wall material for a wooden house or the like that can solve the problem of an irritating odor.

The present invention intends to utilize the properties of porous Okunoto diatomaceous earth as a wall material. In order to be able to use Okunoto diatomaceous earth as a wall material, aggregate, hardener, setting retarder, thickening and moisturizing agent, antifungal agent, and crack prevention material are mixed with the fired powder of Okunoto diatomaceous earth. This is kneaded with water and used as a wall material.
The blending ratio of the Okunoto diatomaceous earth wall material is a hardened material with a mixed powder of silicate sand, natural pumice, and pearlite as the main component (about 41%) and a sintered material of okunoto diatomaceous earth (about 41%). Gypsum (about 25.5%), slaked lime (about 0.5%) and citric acid (about 0.5%) as a set retarder, methylcellulose (about 0.1%) as a thickening moisturizer, fungicides As a benzimidazole preparation (about 0.1%), and as a crack prevention material hemp (1.3%).
The hemp is cut to about 1 cm.

The present invention uses a glass wool heat insulating material in the same manner as a recent inner wall surface structure, and after attaching a plaster board or the like, instead of attaching an interior material such as a cloth, the thickness “5 mm” is used as a plastering work. By applying it to the extent, it is possible to obtain temperature / humidity control, soundproofing / fireproofing effects, and deodorizing effects that are superior to wooden masonry wall houses.

  In other words, it does not require many processes such as wood-blowing work, rough-coating and back-coating work with soil, etc., and instead of pasting interior materials such as cloth, it is about 5mm as a plastering work. If the Okunoto diatomaceous earth wall is constructed, an effect superior to that of the wooden masonry wall can be obtained.

  Furthermore, the main component of the Okunoto diatomaceous earth wall is a baked powder of diatomaceous earth, so it has a fine finish and does not require a top coat finish like a wooden masonry wall.

As described above, the present invention arranges a heat insulating material such as glass wool in the space of a structure made of pillars, beams, penetrations, etc. as an inner wall surface structure, attaches a plaster board, and uses the Nonoto diatomaceous earth wall material as the next step. Are painted as plastering work.
The mixing ratio of the materials constituting the Okunoto Diatomite wall material is as follows.
Noto diatomaceous earth fired powder (about 41%) as the main component, silica sand, natural pumice and pearlite mixture (about 31%) as aggregate, gypsum (about 25.5%) as hardener, slaked lime as setting retarder (about 25.5%) About 0.5%) ・ Citric acid (about 0.5%), Methyl cellulose (about 0.1%) as a thickening moisturizer, Antifungal agent tocitebenzimidazole (about 0.1%), Crack prevention material As hemp (about 1.3%). These are kneaded with water and applied.
In addition, the hemp cut into about 1 cm is used.

Claims (2)

It is a soil wall material that uses aggregate, hardener, setting retarder, thickening moisturizer, antifungal agent, crack prevention material mixed with hemp and then kneaded with water against the fired powder of Okunoto diatomaceous earth. .
The hemp is cut about 1 cm.   The mixing ratio of the earth wall material is as follows: the sintered powder of Okunoto diatomaceous earth as the main component (about 41%), a mixture of quartz sand, natural pumice, and pearlite (about 31%) as aggregate, and gypsum (about approx. 25.5%), slaked lime (about 0.5%) and citric acid (about 0.5%) as setting retarder, methylcellulose (about 0.1%) as thickening moisturizer, benzimidazole as antifungal agent 2.
