Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing wall building materials used for decoration, heat retention, soundproofing, etc.

For example, stones and tiles have traditionally been used as interior and exterior materials, but in order to lay these tiles, mortar was applied to both the base and the tiles, and then they were pasted together. .

However, since it is perilla, mortar tends to sag, and in addition to this, the load of tiles, etc. is added, and especially when the base is plywood, it has the disadvantage that it easily peels off and becomes impossible to stick. There were also technical difficulties that required skill.

On the other hand, there has been a demand for building materials for walls that are easy to handle and have excellent heat retention and sound insulation properties as described above, not only for decoration but also for improving living performance such as heat retention and sound insulation.

Therefore, the present invention solves the above-mentioned drawbacks, and at the same time, mixes cement paste by adding fine aggregate, waterproofing agent, and other admixture materials, and pours the kneaded mixture into a predetermined mold.
This is hardened to form a hard board with flexibility, and a recess is formed on the back of this hard board, and asbestos, calcium carbonate, vinyl chloride resin, and an organic blowing agent are added to the recess, kneaded, and hardened. Conventionally, by forming a porous and elastic flexible laminate made of a hard plate in a fitting manner so that a portion thereof protrudes evenly from the back surface of a hard plate,
In addition to being easy to attach to walls where it was impossible to attach stone or tiles, it has excellent heat and sound insulation properties as well as fire resistance, water resistance, and earthquake resistance, and is extremely easy to cut and work with. The present invention provides an improved method for manufacturing wall building materials.

Embodiments of the present invention will be described below with reference to the drawings.

Cement paste such as Portland cement is mixed with fine aggregate, waterproofing agents, specified coloring pigments, and other admixtures, and then mixed to form a plain color, an appropriate pattern, or a shape imitating the surface of a natural stone wall. The material is poured into a mold B having a rectangular, hexagonal, or other shaped transfer surface to form a hard plate 4 having shearability.

The front surface 1 of the hard plate 4 is formed by the transfer surface of the mold B, and the rear surface 2 is formed with an appropriate number of recesses 3 having substantially similar planar shapes or appropriate shapes.

Furthermore, an appropriate amount of an organic blowing agent is added to asbestos, calcium carbonate, vinyl chloride resin, etc., and the mixture is kneaded and compressed and heated using a hot press plate or the like, or placed in a separate mold together with the hard plate 4 and heated, or A suitable closed-cell porous and elastic flexible laminate 5 is formed by blowing in an appropriate inert gas and performing foam molding.

Then, the flexible laminate 5 is joined to the recess 3 of the hard plate 4 so that a portion thereof protrudes from the back surface 2 with a uniform thickness, thereby forming the wall building material A.

In addition to the generated curing heat, forced means such as steam curing, pressurization, heating, cooling, drying, etc. can be synergistically used to accelerate the forming of the hard plate 4 and the flexible laminate 5.

Furthermore, in order to improve bondability and reduce weight, powder of the flexible body may be added to the cement paste in advance as part of the admixture.

In addition, the flexible laminate 5 is formed and placed in advance, and the rigid plate 4 is
Alternatively, the kneaded material may be placed in the recess 3 of the flexible laminate 5 and bonded with an adhesive, or the kneaded material may be applied and hardened onto the flexible laminate 5 of the flexible laminate 5.

The wall building material A constructed as described above is used by applying a suitable adhesive 6 to a slightly thick layer on the flexible laminate 5 and pressing it onto the wall.

Therefore, according to the present invention, the recess 3 on the back surface 2 of the hard plate 4
Since the flexible laminate 5 is joined in a fitted manner, the hard plate 4 and the flexible laminate 5 can be joined reliably and stably.

In addition, since the hard board 4 is formed by adding a waterproofing agent, the hard board 4 itself has water resistance, which eliminates the unnecessary work of applying a waterproofing agent after construction, unlike conventional masonry materials, blocks, etc. There is no need for

Furthermore, since asbestos, calcium carbonate, hinyl chloride, etc. are used as materials for the flexible laminate 5, the flexible laminate 5 does not allow moisture to pass through, has excellent moisture resistance, and does not corrode. It is nonflammable and has low strength.

Moreover, it is possible to improve the bondability with the hard plate 4 and prevent the hard plate 4 from cracking or falling off.

In addition, since the flexible laminate 5 is formed into a porous, closed-cell foam, it does not impregnate moisture, significantly reduces weight, and has extremely good elasticity, heat insulation performance, and sound absorption performance. When pasting, the adhesive area with the adhesive 6 increases and reliable adhesive strength can be obtained.

In particular, the part to which the adhesive 6 is applied is a flexible laminate 5 that can be elastically deformed, and a part of the flexible laminate 5 is attached to a hard plate 5.
Because they protrude evenly from the back side 2, even if the wall surface to which it is to be attached has a lot of uneven surfaces such as mortar or paint spraying, it can be attached as is, and it also has a good cushioning performance. It has a strong impact resistance.

In addition, since the flexible laminate 5 is placed in the recess 3 provided in the hard board 4, it not only significantly reduces the overall weight of the wall building material A, but also has a low heat transmission rate and a large sound insulation effect, so it retains heat. It can be used as a wall or a soundproof wall, and has an extremely large effect on improving living performance by facilitating air conditioning such as heating and cooling, blocking external noise, etc.

In addition, by mixing the powder of the flexible laminate 5 as part of the admixture material, it is possible to maintain the flexibility of the hard plate 4, improve the bondability with the flexible laminate 5, and prevent cracks. It can be prevented.

The wall building material A formed according to the present invention can be attached to a wall extremely easily and quickly, does not require any skill to attach, and is several minutes lighter in weight than conventional stones, tiles, etc. It can sufficiently withstand loads even on walls to which conventionally it was impossible to attach stones or tiles, and its range of use can be significantly expanded.

Furthermore, since it is extremely easy to drill holes or cut with a saw, it can be freely adapted to the size and shape of the wall to which it is mounted, and it can also be fixed with screws.

In addition, it is easy to handle and process, so it can be directly attached to any base without the need for undercoating or intermediate coating with mortar, unlike conventional stone or tile installations. Man-hours can be significantly reduced.

As described above, according to the present invention, it is lightweight, nonflammable, has excellent water resistance, heat retention, sound insulation, and earthquake resistance, and can be imitated to natural stone.
It is possible to obtain a building material for walls that is rich in decorative properties such as being able to be colored in a variety of colors, is easy to construct and handle, and can significantly contribute to labor-saving work.
