Description
COMPOSITE PANEL AND METHOD OF MAKING THE SAME
BACKGROUND OF THE INVENTION
1. Field of the Invention This invention relates to a composite panel for buildings, more particularly to a light-weight composite panel containing wood fibers.
BACKGROUND OF THE INVENTION
1. Field of the Invention This invention relates to a composite panel for buildings, more particularly to a light-weight composite panel containing wood fibers.
2. Description of the Related Art Building structures, such as building walls, are generally constructed by bricking or forming concrete, followed by application of a concrete cement to the outer surfaces of the building structures for flattening and finishing. However, bricking is laborious as bricks have to be stacked one by one . Forming concrete is time-consuming and laborious as it is necessary to erect mold panels, to pour and solidify a concrete cement, and to disassemble the mold panels . Furthermore, brick walls or concrete walls are generally thick and occupy a lot of space or area so that they are not suitable for use as partitions for buildings, especially those having limited spaces.
Light-weight panels have been commonly used in the construction of partition walls, in place of brick walls and concrete walls. In use, a plurality of light-weight panels are assembled to form a core component, and a concrete cement is applied to two outer surfaces of the core component to finish a partition wall . Assembly of such light-weight panels reduces time and labor and requires less space compared to bricking and concrete-forming.
The aforesaid light-weight panels are typicallyprovided with fire-retarding, sound-insulating, and heat-insulating properties. One of the commonly used light-weight panels is a calcium silicate panel which has excellent fire-resistance. However, the calcium silicate panel is expensive and has poor sound-absorbing property.
Another type of the light-weight panel is a wood-a concrete cement composite panel which is fabricated by dipping wood fibers in a calcium chloride liquid for antisepsis purposes and for the lowering of firing points.
The wood fibers are then mixed with a concrete cement and molded. In such a panel, the wood fibers are used to provide sound-absorbing and heat-insulating (low heat conductivity) properties. However, the hardness and thefire-resistance thereof are not as high as those of bricks, concrete, or calcium silicate panels. Moreover, in assembly, it is necessary to apply a thick layer of cement to the composite panel in order to increase strength and fire-resistance.
Therefore, assembly of this type of composite panel is also time-consuming and laborious.
SUI~iARY OF THE INVENTION
The object of the present invention is to provide a heat-resistant, sound absorbing, fire-resistant composite panel through which a building wall can be constructed easily without consuming much time and labor.
According to the present invention, a composite panel comprises: a wood fiber plate including wood fibers, calcium chloride, a fire-retarding agent, and a concrete cement ; and a cement layer connected to the wood f fiber plate and containing a concrete cement, and a resin.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring.to Figures 1 and 2, a composite panel 1 embodying the present invention includes a wood fiber plate 10 and a cement layer 20.
The wood fiber plate 10 is made of wood fibers 11 which are blended with calcium chloride, a fire-retarding agent and a concrete cement . The wood f fibers 11 may be obtained byextracting fibers from so-ft woods ina conventional manner.
Examples of soft woods are palm and coconut trees.

Referring to Figure 3, there is shown a building wall constructed by usingthe composite panell. In construction, a plurality of the composite panels 1 (only one is shown) are first assembled to form a building wall. After the composite panels 1 are assembled to form the building wall, finishing work may be conducted by applying a thin layer 30 of a concrete cement or a paint to two opposite wall surfaces of the building wall.
Referring to Figure 4, a method of making a composite panel 1 according to a preferred embodiment of the present invention is shown to include the following steps:
In step (A), the wood fibers 11 are prepared. The preparation may be made by obtaining the,wood fibers 11 from raw soft woods, or recycled woods in a conventional manner.
In step (B) , the wood fibers 11 are mixed with calcium chloride, the fire-retarding agent, and a concrete cement.
The calcium chloride is used as an antiseptic agent . The fire-retarding agent can increase the firing-point of the wood fibers 11, whereas the concrete cement is used as a binder.
In step (C), the wood fibers 11 which have been mixed with calcium chloride, the fire-retarding agent and a concrete cement are pressed and formed into the wood fiber plate 10.
In step (D), a mixture of the concrete cement and the resin is poured into a mold. During the pouring of the mixture, the reinforcing web 21 is embedded in the mixture .
In step (E), after the mixture of the concrete cement and the resin has been poured into the mold, the wood fiber plate l0 is placed into the mold over the mixture of the concrete cement and the resin. Since the concrete cement and the resin are binders, they are bonded to the wood fiber plate 10, thus forming a unitary panel body in step (F).
In step (G) , the unitary panel body formed in the mold is sent to a vacuum furnace (not shown) for vacuum drying.
Finally, the composite panel 1 which has fire-retarding, sound-absorbing and shock-resisting properties is formed.
