Abstract

The utility model discloses a hollow composite board, which is mainly composed of a board core and a composite panel, wherein, a hollow cancellate framework which is formed by the solidification of magnesium chloride, magnesium oxide and mixtures of additives is used as the board core; either surface of the board core is provided with a composite panel, or both surfaces of the board core are provided with composite panels. Compared with the prior art, the utility model has the properties of light weight, high strength, sound isolation, heat preservation, flame retardation, corrosion resistance, etc., and meanwhile, the utility model has the advantages of low cost, long service life, etc.; the utility model can be widely used for the decoration of partition walls, door boards, furniture, walls, ceilings and grounds.

Description

Hollow composite board

The utility model provides a kind of Hollow composite board, relates to architectural decoration material field.

At present, the domestic dalle that generally uses mainly contains three-ply board, five-ply board, Planar Compound plate, carving composite plate etc., and three-ply board and five-ply board cost are higher, and is inflammable, perishable, application life is shorter; Performance fire-retardant, corrosion-resistant, long service life that existing composite plate has, but these composite plate sound insulations, heat-insulating property is poor, quality is heavier, is difficult to use as body of wall.

The purpose of this utility model is to provide a kind of lighter weight, has a Hollow composite board of good fire-retardant, sound insulation, heat-insulating property simultaneously.

For achieving the above object, the utility model is taked following technical scheme: the Hollow composite board that is provided mainly is made of plate core and composite panel, the plate core is the hollow latticed skeleton that the mixture of magnesium chloride, magnesia and additive forms through curing, on arbitrary surface of plate core or two surfaces composite panel is set.

Be to guarantee the fire resistance and the intensity of composite plate, composite panel is composited by glass fabric or carbon fiber sheet layer and packed layer.

According to actual needs, as when being used for door-plate, in the space of plate core, be provided for the wooden unit of fixed connecting piece (hinge, door lock etc.).

As shown from the above technical solution, because plate core of the present utility model is the latticed skeleton of employing hollow, the surface coverage composite panel of skeleton has strengthened its sound insulation, insulation, decorative effect, has alleviated the weight of sheet material, has reduced cost; Panel and plate core adopt composite material, make to possess good fire-retardant, decay resistance, and application life is long simultaneously, the scope of application is wide; This composite plate can be used for the decoration on partition wall, door-plate, furniture and wall, top, ground.

The utility model is described in further detail below in conjunction with accompanying drawing:

Embodiment one: at first halogen sheet (magnesium chloride) being added water, to be mixed with mother-in-law U.S. degree be the solution of 23-32, be commonly called as " chlorine liquid " (its concentration can be selected according to requirement of strength), in chlorine liquid, add magnesite modification agent and filler (as sawdust, French chalk, glass fiber etc.), stir and add light-burning magnesium powder (magnesia) after 15-20 minute, stirred 10-15 minute, make it to be scattered paste shape, can add an amount of pigment such as iron oxide red therein as required, chrome green or weaving are with mill base etc., with release agent (as machine oil, lubrication oil, soap lye etc.) evenly be sprayed in the mould, again the above-mentioned mixture example for preparing is gone in the mould, vibration, smooth, closely knit, spread one deck polyester film then thereon, with heat and moisture preserving, the demoulding after 12-24 hour, promptly produce plate core 1 as shown in Figure 2, last on plate core 1, soffit is by the bonding composite panel 2 of bonding agent, as Fig. 1, shown in Figure 5; Composite panel 2 is composited with packed layer 4 by glass fabric or carbon fiber sheet layer 3.

Embodiment two: the making of plate core 1 is identical with embodiment one, plate core 1 vibration, smooth, closely knit after, the layer of glass that tiles thereon cloth or carbon fiber sheet layer 3, evenly divide one deck embodiment one described mixture for preparing on it as packed layer 4, add layer of glass cloth or carbon fiber sheet layer 3 (specifically lay the layer data actual needs and decide) more thereon, one deck polyester mould layer that tiles at last, 12-24 hour rear demoulding can be produced single face Hollow composite board as shown in Figure 3.

Embodiment three: preparation method according to actual specification, before covering composite panel 2, presets wooden unit 5 at the place, space of plate core 1 with embodiment one or two, so that hinge, door lock, junction plate etc. are installed, and as shown in Figure 4.

According to actual needs, for increasing timber intensity, can in plate core 1 and composite panel 2, preset reinforcing bar, wire lath or bamboo chip.

In addition, Hollow composite board provided by the utility model can be made into Planar Compound plate, carving composite plate and Composite covering.
