Description

A kind of composite plate and preparation method thereof
Technical field
The present invention relates to a kind of building material fields more particularly to a kind of composite plate and preparation method thereof.
Background technology
Composite plate is usually the wood composite body made of two kinds of sandwich layer and surface layer material gluing of different nature, commonly referred to as For filled board, its dash board is generally all relatively thin, and sandwich layer is then thicker, and this laminar structure is actually a kind of shell structure.Table Layer, generally common veneer, thin glued board, thin fiber plate, veneer or paper dalle.And the material of sandwich layer be mostly wood shavings, Fiber, particles, bagasse, sawdust, cotton stalk particle or light foam etc..
As needed, the two major classes such as sandwich layer solid core and hollow can be also divided from structure；It is produced using these materials, Ke Yiti High timber utilization rate, more important is its composite effect is utilized, to improve the physical and mechanical property of material.It is steady such as to improve size It is qualitative, keep density small and bending rigidity increase, and increase the performances such as the heat-insulated of material, fire prevention, wear-resisting, corrosion-resistant；It is wooden multiple Influence of the sandwich layer of condensation material with structure to its physical and mechanical property is very big, if as light weight type structural material, sandwich layer is optional Select the structures such as light or hollow wooden frame.
If as sound insulation, heat-barrier material, it is less that sandwich layer can be selected density, intensity also not high material, such as cork wood, foam plastic The light porous materials such as material.No matter what material is selected to make surface layer and sandwich layer, they are intended to make their glue securely with adhesive It is combined.If the two is cementing loosely, dash board material will be removed with core plate and cause to destroy；Therefore the material in glue and sandwich layer Matter structure plays critically important effect；However it can usually be caused due to transportation problem or construction problem in construction or transport The scratch of composite surface causes the damage of composite plate, wastes cost.
Noise pollution not only damages the sense of hearing of people, and can cause cardiac-cerebral vascular diseases.In industry prosperity area and hand over Lead to busy city have become one of mankind's public hazards, since it is simplest block ear with finger, people just use various sides Method hinders the conduction of sound：In fibres such as packing of external auditory canal cotton mass, although easily noise-reducing effect is bad.People Also use various soft plastic products as sound-deadening material, can substantially be divided to two classes：Non-foam material and expanded material, the former Including molded rubber article and plasticity blob of viscose, due to human body difference, molded rubber article is difficult to meet proprietary requirement.Cause People and different molding is pretty troublesome, and bring difficulty to large-scale production, plasticity blob of viscose is not easy to be full of duct, and is difficult to take Go out.The above design does not all account for the construction and specific resonant frequency in human ear road, and decaying is generated in entire voiceband, although Energy noise-decreasing simultaneously also makes one that normal speech exchange can not be carried out, and makes troubles to a few thing, life.Also someone designs On the one hand increasingly complex device, such as electronic filter prevent noise, on the one hand transmit voice signal, and this device price is high Expensive, using trouble.Somebody loads onto double glazing when redesigning glass, that is, is unfavorable for radiating, and also influences the circulation of air.
Meanwhile the continuous improvement required to the fire-protection ratings of building and ornament materials now with country is, it is specified that three layers or more Building must reach A grades of fire prevention indexs, since common aluminum composite plate only up to reach B grades of fire prevention indexs, so A grades of research and development Refractory compound aluminium plate, this aluminum composite plate are had reached A grades of fire prevention indexs of highest fire-protection rating, had both been met generally using the plank The aesthetic of decoration, while improving security performance.
