On the other hand, in water glass-based lightweight plates (foam-hardened ones, or molded lightweight aggregates such as perlite with water glass as a binder), the bonding strength of dry or reaction-hardened water glass is relatively strong. Since it is possible to obtain lightweight and high-strength boards, a lot of research has been done on it, and some of it has even been commercialized. However, since this system essentially contains a strong alkali,
It has drawbacks in terms of water resistance and efflorescence. Various efforts have been made to modify water glass and research and develop hardening agents to address these shortcomings, but as satisfactory water resistance has not yet been achieved, its applications are limited. .

As mentioned above, the composition used in the present invention consists of the above-mentioned components, and the blending ratio is 2 to 100 parts by weight of component B, 2 to 50 parts by weight of component C, per 100 parts by weight of the solid content of component A. and a suitable amount of water mixed as necessary (A+B1C)
The ratio of the amount of component D to the amount of component D is such that the total component (A + water) and the amount of component D is 2 to 40 parts by volume (A + water) and 100 parts by volume of component D.

If the amount of component B is less than 2 parts by weight with respect to component A, the exothermic reaction will be weak and the paraffinic hydrocarbon component C will not be sufficiently melted, so water repellency will not be uniform. The curing reaction of component A also does not proceed, resulting in insufficient water resistance. On the other hand, if the amount exceeds 100 parts by weight, the reaction becomes extremely fast and violent, which causes difficulties in manufacturing operations, and the air bubbles inside the lightweight body become extremely porous and non-uniform, resulting in poor physical properties such as strength.

If the C component is less than 2 parts by weight, a lightweight body with water resistance and water repellency, which is the original objective, cannot be obtained. Moreover, if it exceeds 50 parts by weight, the content ratio of the combustible composition becomes relatively large, resulting in a loss of fire protection performance, which is not desirable.

For example, those with a melting point lower than 40° C. are undesirable because paraffin softens when exposed to high temperatures such as in summer, resulting in stains during handling and deterioration in physical properties. Moreover, those having a melting point of 95° C. or higher are not desirable because paraffin melting due to reaction heat remains insufficient during the reaction process of the present invention, resulting in variations in water-repellent effect.

Further, the paraffinic hydrocarbon used may be in the form of either a powder or a water-dispersed emulsion. For example, in the case of powdered paraffinic hydrocarbons, the finer the particle size, the better; coarse particles or lumps are unsuitable because they cause uneven dispersion, and usually the particle size is l vsva
The following are desirable.

If the above-mentioned so-called binder component (A4-B+C) is less than 2 parts by volume per 100 parts by volume of component D, the lightweight aggregates will not be sufficiently bound together, and the desired strength will not be achieved. It is not possible to obtain a lightweight body with 4.
If the amount exceeds 0 parts by volume, uneven cavities will be created inside the lightweight body, resulting in a decrease in heat insulation and strength.

The method for producing the composition of the present invention involves uniformly mixing the components (A+B+C+water) and component D, which is a lightweight aggregate, and filling the mixture into a plate-shaped, block-shaped, etc. formwork and hardening the mixture. In that case, the mixing order of each component is not limited as long as it does not interfere with the reaction. In some cases, it is also possible to heat the material itself, or to heat the entire material after filling, in order to accelerate the reaction. In addition, in addition to these basic ingredients, hardening agents for water-soluble alkali metal silicates such as aluminum phosphate, zinc oxide, and alumina cement,
Powder fillers such as calcium carbonate, silica sand, and clay, additives such as surfactants, and strength reinforcing agents such as fibrous substances can also be blended. Moreover, it can also be used in combination with a core material such as a honeycomb core as a panel core material.

What is noteworthy about the present invention is that the moisture in the compound evaporates due to the self-heating generated during the reaction curing process, and at the same time, the paraffinic hydrocarbon of component C added inside melts, both inside and on the surface. A water-resistant lightweight body can be obtained in which the entire lightweight body has a structure that is uniformly water-repellent.

Conventionally, a method of adding paraffin wax inside to impart water-like properties has been attempted with gypsum building materials and the like. However, in these cases, it is not enough to simply add
In order to make the resin more water repellent, an additional step of heat treatment at a temperature higher than the melting point of the added paraffinic hydrocarbon is required as a post-treatment after curing. Moreover, in the heat treatment that is a post-process, if the object to be heated is thin, it is relatively easy to heat it to the inside, but if it is thick or block-shaped, it takes an extremely long time to uniformly heat the inside of the object. This wastes thermal energy and is not practical.

Furthermore, if the body is lightweight and has heat insulation properties, it becomes even more difficult for heat to be transferred to the inside, making it even less practical. In this respect, in the present invention, the paraffinic hydrocarbon is integrally melted inside the inorganic lightweight body by actively utilizing the self-heating reaction, so the water-repellent lightweight body is extremely uniform both inside and outside. It can be said that it is extremely effective in that it can be prepared by simple operations of mixing, filling, and leaving without the need for an extra step of post-heating treatment.

As described above, the lightweight body obtained by the present invention can be adjusted to have a specific gravity of about 0.05 to 0.3, although it varies depending on the blending ratio, and is a fireproof and insulating material that is water resistant and water repellent. . Therefore, it has become possible to apply it to areas with moisture, etc., which could not be used with conventional water glass systems. In addition to being used alone as a heat insulating material, this lightweight body can also be used as a fireproof and fireproof core material for sand-inch structural panels in combination with various surface decorative boards, such as decorative asbestos slate boards, colored galvanized iron boards, and colored aluminum boards. be done.

[Comparative Example 4] 1.5 parts by volume (paste prepared by mixing 250 parts by weight of (A-2), 50 parts by weight of (13-2), 10 parts by weight of (C-1), and 50 parts by weight of water) In contrast, 100 parts by volume of D) were mixed. The mixed state was such that the mixed paste was attached to the surface of the pearlite (D). I poured it into a mold as it was and tried to remove it from the mold after the reaction generated heat, but the bonds between pearlite were weak and collapsed during demolding. Therefore, it was impossible to measure the physical properties.

[Comparative Example 5] Unlike Example 8, the amount of the mixed paste (A-2+B-2+C-1+water) was increased to 50 parts by volume, and 100 parts by volume of (D) was mixed therewith. An attempt was made to create a lightweight body by stuffing it into a mold, but the reaction created an uneven space inside. The specific gravity was measured in the state of the plate at the time of demolding, but it was impossible to measure because it was too uneven.
