Abstract
In order to solve the problems that the board bonding in the prior art has the defects that the board cementing surface is likely to de-bond or is weakly bonded, the utility model discloses a large-area board bonding structure. The large-area board bonding structure comprises a layer of net-shaped fabrics on the surfaces of glue films or a layer of net-shaped fabrics between the two layers of the glue films, wherein the thickness of the net-shaped fabrics does not exceed 0.5 mm, so that the invasion to the glue films is better, and the using temperature requirements of the glue films can be satisfied. The large-area board bonding structure disclosed by the utility model has the beneficial technical effects of improving the fluidity of the bonding agent, eliminating or reducing the influences to the bonding quality due to poor matching of to-be-bonded surfaces, assisting in guiding out moisture in the bonding agent of the bonding layer, to-be-bonded boards and the environment and gases guided in the operation process, and avoiding the defects that the board bonding structure is de-bonded or weakly bonded.
Description
Technical field
The utility model relates to a kind of big area sheet material adhesive bonding technique, specially refers to a kind of big area sheet material bonded structure.
Background technology
Splicing is by caking agent (glued membrane), that two or more parts are together bonding, make it to have the structure type of attachment of some strength, connect because having continuous face, stress distribution is even, and the smooth advantage such as smooth of bonded part profile obtains the utmost point and uses widely.The object that sheet material glueds joint is generally the sheet material of matrix material-matrix material, matrix material-metal and metal-metal.Can adopt Chang Zhongwen, high-temperature pressurizing to solidify by service requirements and selected type for adhesive, its forming method generally adopts autoclave-vacuum-bag process method.Prior art sheet material adhesive technology process is: after glueing joint the plate surface processing, at bonding interface paving glued membrane, two boards material that then will be to be gluedd joint puts together, and the most laggard tank solidifies.The contact area of glueing joint due to sheet material is larger, the sheet material that participates in glueing joint is coordinated have relatively high expectations, sheet material splicing face is prone to unsticking or weak sticking defective, particularly when the splicing area is larger, unsticking or weak sticking defective are more obvious, and these defectives may be expanded in using in the later stage of product, cause scrapping of product.Obviously, the splicing of prior art sheet material exists sheet material splicing face and is prone to unsticking or the weak sticking problems such as defective.
Summary of the invention
Be prone to unsticking or the weak sticking problems such as defective for the splicing of solution prior art sheet material exists sheet material splicing face, the utility model proposes a kind of big area sheet material bonded structure.The utility model big area sheet material bonded structure is provided with one deck reticulated on the glued membrane surface, perhaps is provided with one deck reticulated between two-layer glued membrane; The thickness of described reticulated is no more than 0.5mm, and glued membrane is had wetting property preferably, and, can satisfy the use temperature requirement of glued membrane.
Further, the reticulated of the utility model big area sheet material bonded structure is continuous.
The useful technique effect of the utility model big area sheet material bonded structure is the mobility of improving caking agent, eliminate or reduce the bad impact on bonding quality of cooperation of face to be gluedd joint, help to derive the bonding layer caking agent, treat the gas that moisture in bonding sheet material and environment and operating process import, avoided sheet material splicing face the generation of unsticking or weak sticking defective to occur.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model big area sheet material bonded structure.
Below in conjunction with the drawings and specific embodiments being further described the utility model big area sheet material bonded structure.
Embodiment
Accompanying drawing 1 is the structural representation of the utility model big area sheet material bonded structure, and in figure, A is sheet material A to be gluedd joint, and B is sheet material B to be gluedd joint, and 1 is the glued membrane I, and 2 is reticulated, and 3 is the glued membrane II.As seen from the figure, the utility model big area sheet material bonded structure is provided with one deck reticulated 2 on glued membrane I 1 surface, perhaps at two-layer glued membrane, namely is provided with one deck reticulated 2 between glued membrane I 1 and glued membrane II 2; The thickness of described reticulated 2 is no more than 0.5mm, and glued membrane I 1 and glued membrane II 2 are had wetting property preferably, and, can satisfy the use temperature requirement of glued membrane.In order to guarantee to increase the beneficial effect of reticulated, the reticulated of the utility model big area sheet material bonded structure is continuous.When concrete the splicing, first adopt as required the modes such as acid treatment, sandblast alligatoring, mechanical alligatoring, plasma etching to treat to glued joint the surface and process, if adopt the mode of sandblast alligatoring, mechanical alligatoring, need treat after alligatoring and glued joint that the surface is cleaned, drying operation.Waiting to glued joint surperficial paving one deck glued membrane, repave and put one deck reticulated, then, can carry out the glued membrane compensation of 1-2 layer according to mated condition, two boards material to be gluedd joint is put together, carry out at last solidification by cement.
Obviously, the useful technique effect of the utility model big area sheet material bonded structure is the mobility of improving caking agent, eliminate or reduce the bad impact on bonding quality of cooperation of face to be gluedd joint, help to derive the bonding layer caking agent, treat the gas that moisture in bonding sheet material and environment and operating process import, avoided sheet material splicing face the generation of unsticking or weak sticking defective to occur.
Claims (2)
1. big area sheet material bonded structure is characterized in that: this bonded structure is provided with one deck reticulated on the glued membrane surface, perhaps is provided with one deck reticulated between two-layer glued membrane; The thickness of described reticulated is no more than 0.5mm, and glued membrane is had wetting property preferably, and, can satisfy the use temperature requirement of glued membrane.
2. big area sheet material bonded structure according to claim 1, it is characterized in that: reticulated is continuous.
