Description

Construction grass (Fiber) cement board}

.

The present invention relates to interior and exterior boards for building, and in the case of the conventional (Application No. 10-2006-0022930, the name of the invention: pool (fiber) clay water mixture for building interior) replace gypsum board or asbestos rock wool styrofoam Was manufactured by mixing and molding fibers and clays obtained by mechanically decoupling them. However, since they are vulnerable to water and limited to use for building interiors, cemented water is mixed with debris fibers instead of clay water. It is to produce boards and box materials for building interior and exterior that are strong in water and are semi-permanent.

In order to produce new building interior and exterior materials, the present invention is made of grass, which is the main material (all grasses can be used as fiber, but long-leaved rice straw, barley straw, straw, silver grass, grass, grass, etc. It is easy to use as a fiber) and mechanically solved (Application No.: 10-2006-0022930, title of the invention: Mixture of grass (fiber) clay water for building interiors). If you have a lot of moisture in the place and the fire prevention plate and the method of manufacturing the material and the fiber in the plate and the material does not rot easily, increase the tensile strength of the fiber to increase the tensile strength, using a particularly strong fiber It suggests how to make special plates and materials, the mixing order of mixtures, mixing ratios, and manufacturing methods. It is to produce the lumber.

1. How the fiber does not rot well in the wet place and the tension is increased

end. Boil the fiber (2-10 cm) in seaweed for 1-5 minutes in boiling water. (When the grass is mechanically processed, about 90% of nutrients or foreign substances are separated, and the remaining nutrients or microorganisms are separated from boiling water again and do not decay well when used. Also, when boiling grass (fibers) in boiling water, tension is reduced. Is counted)

I. Wash boiled fiber in clear water and dry only pure fiber. (Non-boiled fiber can be used)

2. Specially strong fiber refers to E (것으로), which is boiled for 1 ~ 5 minutes in the same way as the above method. You can make a lumber that has (without using raw fiber)

3. Mixing sequence of the mixture

end. Mix cement and water first. {Water has a high tensile strength after molding and drying so that a small amount of water is easy to mix 20% -30% of the total volume (fiber, clay, water combined volume).}

I. Slowly stir the cement water mixed well like porridge and mechanically dissolve it, mix it with dried fiber (2-10cm), or boil it in boiling water, thinly spread the dried fiber and put it little by little to prevent the fibers from sticking together. (The well-mixed cement water must penetrate the empty space of the dry fiber to have the best tensile strength after molding and drying.)

4. Mixing ratio of building interior and exterior materials and manufacturing method

end. The mixing ratio of fiber and cement is volume (L) ratio

Table 1 Cement to Clay Ratio

The fiber-to-cement ratio is flat and has a tensile strength that can be used as a building interior and exterior material. The volume of the fiber in Table 1 is based on the external volume of the fiber measured by applying pressure to a measuring vessel capable of measuring the volume. (The actual fiber volume is about 35% of the reference volume minus about 65% of the space between the fibers and the space between the fibers.)

I. The mixing ratio of (1) 84:16 to (18) 67:33 in Table 1 is that the more the fibers, the less the tensile strength after molding, drying, and plate, and the weight becomes lighter, and the insulation insulating board for building interior and exterior. Percentage available. (1) 84:16, which contains the most fiber, does not burn well due to cement infiltrating into the fiber.In the case of (1) 84:16, when cement is mixed with a larger amount of fiber, It is difficult to use because of low cohesion.

All. The mixing ratio of (19) 66:34 to (51) 34:66 in Table 1 is a ratio that can produce a plate material for both internal and external insulation, insulation, sound insulation, and fire prevention. (51) If more cement than 34:66 is mixed, the plate can be formed. However, the plate is too hard to be attached with nails, screws or tacker nails.

la. The mixture was mixed at the above mixing ratio, and then molded and mechanically pressurized and dried. {Insulation, heat insulation, sound insulation plate and shell material (1) 84:16 to (18) 67:33 Should be dried under pressure to prevent the fibers from lifting}

hemp. The size of the plate can be made from 90Cm to 150Cm horizontally, 180Cm to 300Cm vertically, and the height (thickness) of 0.5Cm-10Cm can be used. can do.

As described above, the present invention can be used for various purposes according to the ratio as a plate material and a square material made by mixing grass (fiber), cement and water, and the features after plate shape are as follows.

1. Low thermal conductivity makes it easy to control the room temperature because it blocks the hot and cold air from outside in summer and winter, improving thermal efficiency.

2. If the ratio of cement is equal to or higher than the fiber, there is sufficient effect as a fire protection board for the initial fire retardation combustion delay.

3. It is a composite material of fiber and cement, and it has excellent thermal insulation, sound insulation, and can be used as a substitute for wood plywood or lumber.

4. There is little expansion and contraction according to temperature or humidity change, so there is little distortion or seam gap after construction.

5. Easy to attach stone cutting blade to grinder. It is easy to attach with nail, screw and tacker nail.

6. It is easy to construct, which can shorten the construction period and reduce material cost.

7. After the plate is installed, it can be waterproofed, tiled, or plastered on the surface.

8. It can be used semi-permanently because it is strong against moisture and water after construction.
