Background technology
The composite panel of plastic material of prior art, the materials such as most employing polyvinyl chloride, polystyrene are as lamina rara externa, by the composite plate that these materials manufacture, Problems existing is that total quality is heavier, the rear easily distortion of use, between inner interlayer and outside articulamentum, bonding reliability is poor, easily get loose, ftracture, simultaneously much sheet material also exists the defects such as inflammable, compression strength is low, loss of properties on aging, is not suitable for combination property and requires that higher occasion uses.
Summary of the invention
Object of the present invention is exactly the problems referred to above existed for solving prior art, provides a kind of phenolic resins composite laminboard; The present invention is by the coarse process to gluing of surfaces process, strengthen the roughness of gluing of surfaces, the bond area between increase and sandwich of layers, improve adhesive strength, adopt phenolic resins, compression strength is low, resistance to ag(e)ing, quality are light, fire protecting performance good, is specially adapted to the occasion that the composite requests such as fire prevention are higher.
The technical scheme of technical solution problem of the present invention is:
A kind of phenolic resins composite laminboard, comprise the first plate body, the second plate body, sandwich of layers is provided with between described first plate body and the second plate body, described first plate body, the second plate body adopt phenolic resins sheet material, the inner surface of described first plate body, the second plate body is matsurface, and the both sides of sandwich of layers are bonding with the matsurface of the first plate body, the second plate body respectively by epoxide-resin glue.
The matsurface of the inner surface of described first plate body, the second plate body adopts blasting treatment or emery wheel corase grind or sand papering or file processing method to obtain, and the residue produced after effects on surface process carries out clearing up, keeping clean.
The outside surrounding of described battenboard is provided with protective layer; described protective layer adopts phenolic resins sheet material; the inner surface of described protective layer is roughened finish; roughened finish is bonding with the end face of the first plate body, the second plate body and sandwich of layers by epoxide-resin glue, and described roughened finish adopts blasting treatment or emery wheel corase grind or sand papering or file processing method to obtain.
Described first plate body, the second plate body outer surface are provided with projection, and the outer surface of described projection and the first plate body, the second plate body is bonded as one.
Beneficial effect of the present invention:
1. the present invention is by the coarse process to gluing of surfaces process, strengthen the roughness of gluing of surfaces, the bond area between increase and sandwich of layers, improve adhesive strength, compression strength is low, resistance to ag(e)ing, quality are light, fire protecting performance good, is specially adapted to the occasion that the composite requests such as fire prevention are higher.
2. adopt ramming, emery wheel corase grind, sand paper corase grind or filing processing, improve surface processing efficiency, and the residue produced after effects on surface process carries out clearing up, keeping clean, improves bonding force and the intensity of contact surface, reliably bonding.
3. plate body outer surface is provided with projection, and the outer surface of projection and plate body is bonded as one, and adds integral rigidity and the intensity of battenboard, decreases the distortion in use, extend service time.
Detailed description of the invention
In order to understand the present invention better, explain embodiments of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of phenolic resins composite laminboard, comprise the first plate body 1, second plate body 2, sandwich of layers 3 is provided with between described first plate body 1 and the second plate body 2, described first plate body 1, second plate body 2 adopts phenolic resins sheet material, the inner surface of described first plate body 1, second plate body 2 is roughly ground through sandblasting or emery wheel, is made inner surface through surface coarsening process, form coarse interior upper surface layer 4, undersurface layer 5, the both sides of sandwich of layers are bonding with the rough inner-surface layer of the first plate body, the second plate body respectively by epoxide-resin glue.Certainly, the inner surface of the first plate body, the second plate body also can adopt the method such as sand paper, file processing, makes frosting roughening treatment.
The outside surrounding of described battenboard 3 is provided with protective layer 6; described protective layer 6 adopts phenolic resins sheet material; the inner surface of described protective layer 6 is the roughened finish 7 by roughening treatment, and roughened finish 7 is bonding with the end face of the first plate body 1, second plate body 2 and sandwich of layers 3 by epoxide-resin glue.
Described first plate body 1, second plate body 2 outer surface is provided with projection 8, and the outer surface of described projection 8 and the first plate body 1, second plate body 2 is bonded as one.
By reference to the accompanying drawings the detailed description of the invention of invention is described although above-mentioned; but not limiting the scope of the invention; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection scope of the present invention.
