Manufacturing method of artificial building materials

The present invention relates to a method of manufacture, and more particularly to a method for making artificial building materials.

There are many types of artificial building materials. Among them, reinforced concrete with glass fiber is usually mixed with cementing materials such as cement, mineral adhesives, water, aggregates and glass fibers in appropriate proportions, and then poured into the mold. The predetermined thickness is formed in the cavity, and when the mixture is hardened, artificial building materials suitable for use in the construction field are formed.

It is known that in the process of manufacturing artificial building materials, air is mixed in the mixture during the process of mixing and filling the mold holes of the mold, and in the absence of the mechanism of removing air, the artificial building materials after solidification are contained higher. In the proportion of air, since the air forms voids in the solidified artificial building material, it is known that the structural strength of the artificial building material is poor. On the other hand, conventional artificial building materials have poor water repellency. Therefore, when used in places where water contact is required, for example, as a building exterior wall, it is known that artificial building materials also need to be waterproofed, so the cost in subsequent construction is relatively high. High, it is also inconvenient during construction.

The object of the present invention is to provide a method for manufacturing artificial building materials which have better structural strength and can reduce the thickness of the artificial building materials under the same structural strength.

The method of the present invention is for forming an artificial building material, the artificial building material comprising a main structural body comprising a plurality of structural interlayers laminated and composed of cementing materials, aggregates, water and glass fibers, and The method comprises the steps of: preparing a slurry: mixing the cementing material, the aggregate and the water to form a slurry; filling the mold: mixing the prepared slurry together with the glass fiber, and filling the cavity in one of the molds to form a slurry Thin layer; compaction: compacting the thin layer of the slurry to remove internal air; and repeating: repeating the filling step and the compacting step, when the compacted slurry is thin After the solidification, the structural interlayer is formed, and a plurality of compacted pastes are thinly laminated and bonded to form the main structural body.

The beneficial effect of the invention is that the layer stacking of the thin layers of the slurry and the compacting step of the thin layers of the slurry can push out the air entrained in the thin layer of the slurry to improve the artificial The compactness and structural strength of the building materials, and the structural strength of the artificial building materials produced by the present invention are better, so that the thickness of the artificial building materials can be reduced under the same structural strength.

The foregoing and other objects, features, and advantages of the invention are set forth in the <RTIgt;

Referring to Figures 1, 2 and 3, a preferred embodiment of the method of the present invention is for manufacturing an artificial building material 1 as shown in Figure 2, the artificial building material 1 comprising a main structural body 11, and a plurality of embedded in the main A fixing plate 12 inside the structure 11. The main structure 11 includes a plurality of structural interlayers 111 which are stacked on top of each other. The structural interlayer 111 has the same composition and is composed of a cement material, an aggregate, water and glass fibers, in order to improve the waterproofness of the artificial building material 1. In this embodiment, a suitable water repellent can be further added in the process.

The cementing material described in this embodiment comprises: an adhesive for cement and minerals, preferably a cement which does not contain alkali, such as Portland cement commonly known as white cement, and the adhesive for minerals. The function is to increase the structural strength and density of the cement. In this embodiment, latex and glue can be selected, such as acrylic acid (Acrylic polymer) glue.

The aggregate material of the embodiment may be a coarse aggregate having a large particle size, and/or a fine aggregate having a small particle size, and the type of the addition is not particularly limited, and the selection is different depending on the customer's needs. Stone, for example: natural minerals such as quartz sand, limestone, granite, marble, rust stone, mica stone, etc. The glass fiber can increase the flexibility and tensile bending strength of the main structure 11. In this embodiment, a material with good alkali resistance is used, which is chopped into a fine section of 37 to 40 mm. In the blended slurry. The water repellent agent described in this embodiment is selected from the group consisting of perfluoro octanoic acid and perfluoro octane sulfonic acid.

The fixing plate 12 of the present embodiment is a galvanized metal plate having a preferable structural strength, and mainly includes an embedded portion 121 buried inside the main structural body 11, and a fixing portion protruding from the main structural body 11. 122. The embedded portion 121 has a clamping wall 123 sandwiched between two layers of the structural interlayer 111 of the main structural body 11, an extending wall 124 perpendicular to the clamping wall 123, and two The reinforcing wall 125 extends toward the opposite side at the end of the extending wall 124. The fixing portion 122 is integrally extended by the clamping wall 123 and has a through hole 126 through which a screw (not shown) can pass.

In order to manufacture the artificial building material 1 described above, the process of the present invention comprises the following processing steps: preparing a slurry: a total of 50 parts by weight of Portland cement, aggregate and water, 10 parts by weight of acrylic glue, and 10 weights The portion of perfluorooctanoic acid is uniformly mixed to form a slurry for use.

Filling: 30 parts by weight of glass fiber is cut into pieces of 37-40 mm by a spray mixer 2, and sprayed together with the slurry prepared in the foregoing step into a cavity 31 of a mold 3, A thin layer of slurry 19 is formed, which may also be added during the step of preparing the slurry. The spray mixing machine 2 illustrated in Fig. 3 is a coaxial single port structure, and the present invention can also use a double port spray mixing machine, which will not be exemplified. The shotcrete mixer 2 mainly comprises a centrally located fiber channel 21, a cutter 22 at an inlet 211 of the fiber channel 21, and a slurry channel 23 surrounding the fiber channel 21. When the ribbon-shaped glass fiber passes through the cutter 22, it is chopped and conveyed to an outlet 212, and the slurry prepared in the preparation of the slurry step is fed from the slurry passage 23, and then chopped. The glass fibers are mixed and fed into the cavity 31 of the mold 3 to form a slurry layer 19 having a predetermined thickness. The thickness of the slurry layer 19 is about 15-25 in order to facilitate subsequent processing. Mm is preferred.

Compaction: The operation of compacting the slurry layer 19 by a roller 4 for the purpose of pressing out the internal air. When the slurry layer 19 is naturally air-dried, the structural interlayer 111 of the present embodiment is formed.

Repeating: this step is to repeat the filling step and the compacting step, that is, after the thin layer 19 of the slurry is pressed and compacted and naturally dried to form the structural interlayer 111, the filling step and pressure are repeated. The steps are performed to form a second structural interlayer 111. In the present embodiment, when the repeating step is performed, the slurry layer 19 of the first layer is in a semi-dry state, and the second layer of the slurry layer 19 can be sprayed. By analogy, the main structural body 11 having a plurality of structural interlayers 111 can be stacked in layers. In the repeating step, the embodiment selects an appropriate timing to place the fixing plates 12 on one of the structural interlayers 111, and then performs the next repeating step, so that the fixing plates 12 can be used. It is firmly buried in the main structural body 11.

Demolding: The artificial building material 1 is taken out from the cavity 31 of the mold 3. Generally, after waiting for about 48 hours after the completion of the foregoing steps, the slurry can be naturally shrunk to facilitate demolding. In order to make the artificial building material 1 more easily demolded, before the grouting step, the present embodiment can pre-coat a layer of release agent on the inner surface of the cavity 31 of the mold 3, since the release agent is used to assist in demolding. Know the technology, no longer explain.

It can be seen from the above description that the artificial building material 1 of the present invention is formed by laminating and then compacting, and forming the layered and laminated structural interlayer 111 in the cavity 31 of the mold 3, and in each case. After the grouting step, the air in the slurry is extruded as much as possible by the compacting step. The above-mentioned process steps are not only innovative in the manufacture of the artificial building material 1, but also the compactness and structural strength of the artificial building material 1 can be improved. Since the structural strength of the artificial building material 1 can be improved, the thickness of the artificial building material 1 can be reduced under the same structural strength requirements. On the other hand, the invention directly adds the proper proportion of water-repellent agent to the formulated raw material, so that the artificial building material 1 can have the waterproof effect, therefore, the artificial building material 1 not only does not need to be additionally waterproofed after the construction, due to The waterproof effect of the artificial building material 1 of the invention comes from the material itself, and therefore, the problem that the waterproof layer peeling off needs to be re-constructed is not caused, so the manufacturing method of the artificial building material 1 of the invention is not only innovative, but also has good structural strength and strength at the same structure. Reduce the thickness, and have better waterproof effect.
