Description

The composite plate that a kind of environment-friendly light is high-strength

Technical field

This utility model relates to the composite plate that a kind of environment-friendly light is high-strength。

Background technology

Aluminium-plastic panel is as a kind of new decorative material, it is introduced into China from it, just with its economy, the multiformity of optional color, easily construction method, excellent processing characteristics, it is subject to rapidly the favor of people, it is widely used in the places such as meeting room, workplace, cinema and music hall, this is accomplished by aluminium-plastic panel and has the function of noise reduction and sound insulation, most aluminium-plastic panel in the market is unable to reach good erasure effect more, and aluminium-plastic panel is poor in fire prevention and heat-insulating property, it is necessary to improve further。

Aluminum honeycomb panel is the structure being provided with honeycomb type between two-layer aluminium sheet, the structure of honeycomb type is also that aluminium is made, i.e. aluminium honeycomb core, integral with aluminium sheet, honeycomb texture be equivalent to aluminium sheet without several reinforcements, aluminum honeycomb panel is compared with simple aluminium sheet, and its honeycomb texture has certain sound insulation deadening, but effect is general。In existing sheet material, composite plate is difficult to the composite plate with the environmental protection of heat-insulating, fire-preventing noise reduction。

Gypsum wallboard is cheap and is prone to utilize, it is possible to fire-resistant；But, it does not have reinforcing material, it is likely to relatively crisp when dry, and will be unable to support heavy duty。The another kind of material used is silicate-base product。Owing to containing silicate, people (habitant in such as builder or building) and environment are probably harmful by it。

All there is the problem of narrow application range in above-mentioned various sheet material, as sheet material, the most prominent performance is its intensity, and the sheet material of high-strength light is always up the focus of research。

Utility model content

This utility model solves the technical problem that the composite plate being to provide a kind of high-strength light, and this composite plate has certain fire-retardant and heat insulation effect simultaneously。

The technical solution of the utility model is to provide the composite plate that a kind of environment-friendly light is high-strength, and described composite plate is layer structure, sequentially consists of lower aluminum sheet, lower tack coat, haydite concrete layer, upper tack coat, upper aluminium sheet；The upper surface of described lower aluminum sheet and the lower surface of upper aluminium sheet are equipped with passivation layer。

Further, described lower tack coat and upper tack coat are polymer water mud layer。

Further, described passivation layer is epoxy resin layer。

Further, it is equipped with polyvinylidene fluoride resin layer at the upper surface of the lower surface of lower aluminum sheet He upper aluminium sheet。

Further, the thickness of described lower aluminum sheet and upper aluminium sheet is 2-5mm。

Further, the thickness of described haydite concrete layer is 10mm-50mm。

Aluminium sheet is the material that specific strength is significantly high, but simple aluminium sheet has very big applied defect, and as can not be heat insulation, erasure effect be also very poor, by aluminium sheet and macromolecular material, as plastics compound can obtain aluminium-plastic panel。This utility model provides a kind of structural panel by aluminium sheet Yu haydite concrete compound so that composite plate has high intensity, and it is very light to conduct oneself with dignity。Haydite concrete is to replace stone as concrete aggregate using haydite, specifically with haydite for coarse aggregate, is called haydite concrete with the lightweight aggregate concrete that normal sands or pottery sand are fine aggregate。Ceramsite Concrete is lightweight, and its dry density is 800-1900kg/m³, lighter 2/3-1/5 than ordinary concrete, owing to from heavy and light, foundation load can be reduced, thus can make the weight reduction of whole composite plate。

The beneficial effects of the utility model are; haydite concrete belongs to silicate material; there is good fire protecting performance; polymer cement is adopted to make the adhesive bond in composite plate firm as tack coat; for preventing the material corrosion to aluminium sheet of the tack coats such as polymer cement; surface of aluminum plate in that side contacted with tack coat is provided with passivation layer; passivation layer can also with binding material strong bonded; aluminium sheet is combined by this composite plate with haydite concrete layer; the intensity making this composite plate improves; quality lightens, it is possible to be applied to the every field such as heat insulation, fire prevention。

Accompanying drawing explanation

Fig. 1 represents the sectional view of the composite plate that this utility model provides。

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail。

Embodiment 1

The present embodiment provides the composite plate that a kind of environment-friendly light is high-strength, and described composite plate is layer structure, and its sectional view is as it is shown in figure 1, sequentially consist of lower aluminum sheet 1, lower tack coat 2, haydite concrete layer 3, upper tack coat 4, upper aluminium sheet 5；The upper surface of described lower aluminum sheet and the lower surface of upper aluminium sheet are equipped with passivation layer 6; passivation layer 6 is epoxy resin layer; lower tack coat 2 and upper tack coat 4 are polymer water mud layer; it is equipped with polyvinylidene fluoride resin layer 7 at the lower surface of lower aluminum sheet 1 and the upper surface of upper aluminium sheet 5; the thickness of lower aluminum sheet 1 and upper aluminium sheet 5 is 4mm, and the thickness of haydite concrete layer is 15mm。This composite plate has lightweight, the advantage such as high-strength, is especially suitable for use as the building materials field such as partition wall, curtain wall。
