The present invention is for building materials such as heating and flooring materials for building heating and anti-icing heating blocks of civil engineering, blocks for melting snow and roads, airports, harbors, parking lots, etc. Block, public transportation boarding freezing block, ground heating block for agricultural products, heating material for drying crops, thermal block for winter season for fish farms, heating device for snow melting on roof of heavy snow area, heating material for maintaining temperature in outdoor communication center, far-infrared radiation or negative ion effect In the manufacture of heating materials that can be used in all industries, such as well-being facilities such as stone beds, saunas, saunas, etc., various wastes such as construction waste, waste glass, molten slugs, and synthetic resin wastes are replaced with aggregates. Far-infrared planar heating element or other planar heating element using fiber yarn heating fabric is fixed to middle part of aggregate It forming solidified on drying at room temperature by way of a technique colostrum to create a versatile heat generating element.

① The inventors of the present invention devised a ceramic carbon fiber paper plane heating element (Patent No. 0337609) and a carbon fiber yarn heating fabric and a far infrared radiation plane heating element (Patent No. 0491225) using the same. · There are many difficulties in applying to large industrial fields such as civil engineering, agriculture and fisheries. Existing planar heating elements have weakness in impact, contact, moisture, high temperature, cold, bending, chemical change, electric shock, etc. to apply by themselves. Otherwise, it is very difficult, and if the surface heating element is directly exposed to the outside, it may lead to short circuit, short circuit, and shortened product life if the direct heating material is not firmly treated with the surface part or heat insulating part as a protective material. In addition, manufacturing or installing the surface part or the exterior part separately is one of the obstacles to market expansion because the processing cost is higher than that of the planar heating element.

(2) The inventors of the present invention have devised alumina-based hydraulic coagulants mainly composed of silicon, alumina, sodium, calcium, titanium, iron, etc., which have not been inevitably subjected to high temperature forming in the existing product process. Aggregates and coagulants were mixed and then hardened in a mold. In addition, the concrete waste material generated when the concrete structure is collapsed is much generated and is likely to increase further in the future, and is recycled as a recycling method. There is no situation.

The present invention solves the problems described in the above ①, ②, the manufacturing method or manufacturing apparatus technology for manufacturing a complete solidified molding heating material by the room temperature drying method by a simpler process, and many development researchers have tried, but until now It is a product manufacturing technology of colostrum that was not successful.

In the present invention, since the surface or heat insulation of the planar heating element is compressed into a solidified molding material by compressing the surface or the heat insulation part with a low-purity synthetic resin, impact, contact, moisture, high temperature, cold, bending, chemical change, electric shock, etc. It can be configured with very low production cost and very low production cost, so it can maintain absolute price competitiveness in both advanced and developed countries, and in the case of special products (eg drying system for raw material production) Create added value.

In the dry drying solidification method of the present invention, aggregates such as hydraulic coagulants and various inorganic materials or non-hydration organic materials are coagulated about 30% (weight ratio), aggregates about 70% (weight ratio). Homogeneous mixing is carried out at a ratio of) to form a compound, and about 20 to 25% (weight ratio) of water is added to the compound, and homogeneous mixing is performed while generating an equivalent convection with a vacuum apparatus having a special structure propeller. The vacuum device having the propeller of this special structure means that the blades of the stirring pellets having the upper and lower wings of each blade have an inclination of 45 ° with respect to the rotation axis, and the spiral blades in the stirring vessel also cause the liquid and It is a device that can perform homogeneous mixing and agitation so that liquids collide with each other and rise at the bottom of the container to efficiently degas the air in the mixture. It is poured into a mold to stop curing for 6 to 10 hours at room temperature of 20 ~ 30 ℃ to cure and complete the primary completion of the product.

By using the above method, when various waste materials are used as aggregate, the air layer covering the surface of aggregate can be completely removed. By this vacuum method, the adhesion between cement and various aggregates can be dramatically improved. have. The mixture more uniformly mixed by stirring in a vacuum maintains a very stable liquid phase, which is poured into a mold to cure, and the finished product is formed into a stable secondary product with a uniform composition. And by adding 5 to 13% (weight ratio) of high purity activated silica called silica fume to the alumina-based hydraulic coagulant, the heat of hydration due to the long-term compositional stability of the cured product and the initial high temperature hydration characteristic of the alumina-based hydraulic coagulant. ) Can be suppressed. In addition, the secondary (exterior treatment) product manufactured by this method has a transferability of reproducing the surface texture excellently simply by pouring a liquid mixed uniformly into the center of the molding mold in the manufacturing process to perform molding. Inexpensive and simple rubber molds or resin molds can be used without the need for press molding or the like.

The most important point of the present invention is that conventional planar heating elements can not be manufactured by conventional high temperature drying method when the heating element is left standing in an inorganic or organic material mixture. In case of high temperature drying, the planar heating element is deformed due to high temperature and electrical defects are generated, resulting in a defective product or incapable of guaranteeing the life of the product. In addition, the mixture itself undergoes a deformation of the form during the high temperature process and results in the inability to accurately manufacture the standard product.

In the present invention, the planar heating element is left at the position in the mixture in the mold and mixed with inorganic material or organic material and flows into the lower and upper parts of the planar heating element which is left in the mold to dry at room temperature to prevent bubbles or cracks in the mixture. It is to make a perfect solidified molding heating element.

First, the present invention shown in FIG. 1 shows the planar heating element 21 in the mold 11 and mixes the compound in the lower part of the planar heating element 21 and vacuum stirs (see FIGS. 5 and 6). The aggregate mixture 32 is introduced by filling it with a planar inlet to prevent air from intervening, and the mixture is mixed on the planar heating element 21 to form the upper aggregate mixture 31 that is vacuum stirred (see FIGS. 5 and 6). 11) Fill it up to a height and move it to a place of normal temperature drying.

In the present invention, the main material of the aggregate used at this time is to mix up to 50-70% of the crushed products, waste glass crushed, dissolved slugs, synthetic resin waste crushed, waste tire crushed, etc. of the building waste, and together with the silica sand, cement, etc. The water-based coagulant and water were mixed, and then stirred in a high-speed mixed stirrer and a vacuum stirrer (see FIGS. 5 and 6) to be introduced into the mold.

In the prior art, sand, finely divided stones, cement, and other materials are mainly used as the main materials of aggregates, and are mainly composed of artificial marble and decorative tiles, and most of them are mixed through medium or low speed mixers.

Recently, as a part of the environmental industry (recycling), a special plastering company has adopted a manufacturing method that uses a mixture of construction waste and waste glass crushed products as aggregates, but the drying method uses petroleum fuel (mainly banca C oil or gas). Only high heat treatment is used.

In addition, the artificial marble prepared by the prior art is a process to polish the surface portion to the gloss, and the high pressure glass marble of the plate glass manufacturing method, which is recently increasing, also requires high energy.

One of the characteristics of the present invention is that the mold 11, which is transferred to a room temperature drying place, the non-coagulated moldings are placed on a multi-stage drying rack maintained at 20 to 30 ° C., and the primary product is stopped by natural drying for 6 to 10 hours. It is a finished, non-powered, non-heat treatment drying method.

In this case, the molding die 11 of the present invention can be used as a synthetic resin mold such as rubber mold or urethane and PP, unlike the prior art, and thus, the cost required for manufacturing the mold is very low, and the molding die surface portion 12 It can be designed in various ways and has the advantage of being able to respond quickly to the interior or exterior of buildings. (See [Fig. 7, 8, 9])

Meanwhile, in the present invention, the components of the upper and lower aggregate mixtures 31 and 32 bounded by the planar heating element 21 in the mixing process of the mixed lower aggregate mixture 32 in the lower part of FIG. In other cases, it is possible to achieve good functionality. That is, the upper aggregate mixture 31 is further mixed with ceramic and silicon (Si) powder having excellent thermal conductivity so as to improve thermal conductivity, and to the lower aggregate mixture 32. In the case of the waste foamed styrople pulverized product or the waste tire pulverized product having excellent thermal insulation property, the thermal insulation property can be improved.

In order to simultaneously supply the above-described aggregate mixture for improving thermal conductivity and thermal insulation to the work process, a plurality of mixed stirrers and vacuum stirrers on the process flow of FIG. 6 are provided in the lower position of the mold 11 of FIG. In the lower aggregate mixture 32, the upper aggregate mixture 31 in the upper position is introduced in sequence.

2 is a perspective view showing the external appearance of the solidified mold heating member 33 of the present invention.

Since the solidification type heating material of the present invention can be applied to a wide range of industrial fields such as construction, civil engineering, agriculture and fisheries, etc., it must be manufactured in various sizes and connected or assembled. This molding material is manufactured by inserting the joining brackets. It is easy and fused very well with the ground agent, adhesive, adhesive, etc. used in general artificial marble or tile, and the special adhesive materials devised by the present inventors are excellent in attaching or bonding the molding materials of the present invention. It is convenient to have performance.

On the other hand, the surface portion of the upper aggregate mixture 31 of the solidified molding heating material can be produced in various ways according to the design of the mold, as shown in Figure 8, 9, 10.
In addition, reference numeral 22 is a power supply, and serves to supply current to the planar heating element (21).

3 is a perspective view of the product configuration of the solidified mold heating material 33 of the present invention.

The heating part of the solidified molded heating material 33 may use a linear heating element, but there is a disadvantage in that the process time is increased in the work process, and the time required for initial thermal conduction is longer, and the linear heating element has a single wire structure because the heating wire is generally a single line structure. When short circuit occurs, it may cause big inconvenience to replace the unit product itself. Therefore, the present inventors are based on using the planar heating element 21 as the heating element.

In addition, the planar heating element used in the manufacture of the product is most suitable to use microfiber carbon fiber yarn or aluminum sheet as a heating material, and the insulation part is best bonded to the coagulant used in the aggregate mixed with the flexible polymer synthetic resin sheet. .

Although the upper aggregate mixture 31 of the solidification-type molded heating material has been described in FIG. 2, it is possible to produce a wide variety of products depending on the surface treatment material.

It is possible to produce high-quality heating materials by joining wood plates and veneers on the molded surface or in the process of molding.They are made of high-grade heating materials such as ceramics, Si, tourmaline, germanium and other negative ions. It is not difficult to manufacture the well-being health facility material by surface treatment of the ore that comes out.

In addition, it can be used as a main material for thermal stone bed, thermal bed, thermal living room floor, etc., which is the safest and easiest to manufacture if it is treated with ocher, flour, porcelain, and jade powder, which are widely used for health. Water veins can also be solved very easily (see Figures 8 and 9).

In addition, if the elastic heat-resistant nonwoven fabric is bonded to the surface of the upper aggregate mixture 31 with a special binder and the Japanese-style tatami is externally treated, it is possible to make a heated tatami and the textile fabric and the like on the surface of the upper aggregate mixture 31. The application range is very wide even in the field of building materials. (See Fig. 10).

The solidification-type molding heating material has a maximum size of 1000 × 2000 mm, which is easy to manufacture, and inserts a decorative decoration 51 on the side of the solidified lower aggregate mixture 32 when necessary for connection bonding. I can make it.

Figure 4 is a perspective view of a solidified molding heating material used in the civil engineering, agricultural and fisheries field of the present invention is produced in the form of blocks and can produce products of various specifications according to the use.

In the case of mixed upper and lower aggregate mixtures 31 and 32, the recycling of waste described in FIG. 1 may be used in a large amount, and the strength and hardness may be adjusted according to the use, and the waterproofing function may be enhanced by the density of the coagulant. .

In addition, in the case of agricultural and fisheries, artificial zeolite may be mixed in the upper and lower aggregate mixtures 31 and 32 to produce the land and to improve the water quality, and to promote the growth of the crops and to control the winter temperature of the fish farm.

5 is a perspective view showing the power connector 24 for electrical connection between the solidified mold heating material of the present invention.

In the four directions of the side surface of the molded heating material for electrical connection between the planar heating element 21 which is stationary between the upper and lower aggregate mixtures 31 and 32 of the solidified molding heating material and the surface heating element of another heating material. Insert and fix the power connector 24 of the waterproof type, and the electrical connection between the heating element and the heating element by inserting a dedicated connection pin. Waterproof power connections shall use approved standard products.

First, a mixture is formed by uniformly mixing hydraulic coagulants with aggregates such as various inorganic materials or non-hydrated organic substances at a ratio of about 30% (weight ratio) of the coagulant and about 70% (weight ratio) of the aggregate. About 20-25% (weight ratio) of water is added with respect to this compound, and mixing and stirring are performed at high speed using a high speed magera, a high speed stirrer, etc.
