Abstract
The utility model discloses a kind of light composite board, by upper epidermis, lower bottom and intermediate layer three ply board material, be combined to form, wherein upper epidermis and lower bottom are superficial layer, upper epidermis and lower bottom are hard reinforcing materials, it is characterized in that, intermediate layer is a composite construction layer, the foams that described composite construction layer is made by fiberfill fibers enhancing phenolic resins and the compound formed complex of skeleton of honeycomb.The utility model utilizes phenolic resins for inserts matrix on the one hand, guaranteed the fire line of composite plate, on the other hand, at chopped strand, strengthened in Foaming of phenolic resin central layer and introduce honeycomb, thereby realized good heat insulation, sound insulation value, composite plate overall mechanical properties is excellent simultaneously.By one-body molded, even work, can there is not the risk that central layer and motherboard rupture and subside under dither environment in this kind of composite plate yet.
Description
Technical field
The utility model relates to a kind of light composite board material, and particularly both sides are surface material, and centre is the retardant foam composite board of light material.
Technical background
Carrying means of transport of today requires material energy-saving conventionally, fire-retardant, comfortable, sound insulation value is excellent, this kind of material is mainly used as floor, wallboard, the top board of carrying means of transport, producer generally adopts cellular structural material both at home and abroad, and this material is that intensity is high, quality is gently famous.Number of patent application is in 200510041553, Xue Binkai is by cellular material and the compound honeycomb composite plate core board of having prepared of blank material, but owing to just adopting merely honeycomb skeleton as intermediate layer, so product easily in use caves in and cannot reply; Number of patent application is in 201020535333, and Zhao Huihua utilizes aluminium sheet motherboard and PP central layer to make PP honeycomb composite plate, and this kind composite plate is fire-retardant, heat-insulating property is poor.Utility application numbers 2012220250571.7 utilizes reinforcement reinforced panel to make phenolic foam composite plate, and this composite plate, because phenol formaldehyde foam is in the limitation aspect mechanical property, is difficult to structural member and uses, and is generally used for insulation material.
The risk that market honeycomb composite plate used use under dither environment now the fracture of central layer and motherboard can occur and subsides, and sound insulation value is poor, therefore needs to be further improved.
Utility model content
The utility model is for the deficiency of existing honeycomb composite plate sound insulating sheet material performance and fatigue performance, a kind of new honeycomb composite plate is proposed, this kind of honeycomb composite plate can greatly strengthen the mechanical performance of composite board, and realized that composite plate is well heat insulation, fatigue durability.
The utility model is by the following technical solutions: a kind of light composite board, by upper epidermis, lower bottom and intermediate layer three ply board material, be combined to form, wherein upper epidermis and lower bottom are superficial layer, upper epidermis and lower bottom are hard reinforcing materials, it is characterized in that, intermediate layer is a composite construction layer, the foams that described composite construction layer is made by fiberfill fibers enhancing phenolic resins and the compound formed complex of skeleton of honeycomb.
Further, described cellular structural material is hexagon honeycomb or is quadrangle honeycomb, is filled with the foams that fiber reinforcement phenolic resins makes in the cavity of hexagon honeycomb or quadrangle honeycomb, is combined to form composite construction layer.
Further, described hexagon honeycomb adopts aluminium foil or aramid paper to make moulding, and aluminium foil or aramid paper adopt different hexagon back gauge moulding; Wherein, hexagon honeycomb aluminum foil thickness, the length of side and be highly respectively 0.03-0.10mm, 2-10mm and 5-30mm; The hexagon honeycomb aramid paper length of side and be highly respectively 2-5mm and 5-30mm;
Further, described quadrangle cellular composite material thickness, the length of side and be highly respectively 0.5-2mm, 10-100mm and 5-30mm.
The utility model utilizes phenolic resins for inserts matrix on the one hand, guaranteed the fire line of composite plate, on the other hand, at chopped strand, strengthened in Foaming of phenolic resin central layer and introduce honeycomb, thereby realized good heat insulation, sound insulation value, composite plate overall mechanical properties is excellent simultaneously.By one-body molded, even work, can there is not the risk that central layer and motherboard rupture and subside under dither environment in this kind of composite plate yet.
Compared with the prior art, the utility model beneficial effect is embodied in:
