invention: [Technical field to which the invention belongs] The present invention relates to a stone sheet, and more particularly, to a stone sheet composite reinforcing material capable of enhancing the effect of bonding and fixing, and a process therefor. Dajintian [Prior art] See the picture! So ^ '— when the general stone sheet composite material lG is prepared, first, a stone sheet u is prepared, and a resinous bonding material 12 is layered on the back of the stone sheet u, and then the same as the stone sheet u is cut; The big back plate 13 of 15 20, and then the backing plate η is pasted on the back of the stone sheet u =. With the adhesive force of the bonding material 12, the stone sheet u: 13 can be combined and fixed. After the composite material 10 has a predetermined size and thickness, after the composite material 10 is completed, the manufacturer can perform a post machining or grinding process on the stone sheet so as to obtain a final product and a smooth and shiny surface. Although the above manufacturing technology can make the stone sheet 11 with a certain thickness = composite material! 〇 structure, in order to facilitate the mechanical grinding and polishing of the stone sheet u: The temple processing 仃 is' However, the above composite material 10 structure will result in the following defects: 1. The whole material scale is easy to make money, the composite material 1G is mainly used for stone material 4 The plate 11 and the backing plate 13 are adhered to each other by the joint material 12. Although the thickness of the sheet U and the backing plate 13 can be controlled by machining, the bonding material 12 is a viscous liquid that is fluid. , Its thickness is easy to have unevenness due to the amount of 1 = 'and the stone sheet U and ::: 2: 3 are both in the Lihe, the adhesive material 12 is easy to overflow from the side of the dust' S adhesive material 12 is hardening The volume of the post-bonding material 12 will shrink by 200521302. Therefore, the composite 1G finished products are often thicker and thinner, so the plane accuracy and size setting of the subsequent grinding process will be reduced. Become difficult. 2. The bonding strength is not good. The stone sheet 11 uses the bonding material 12 and the backing 5 & 13. The combination of the two is very important. Traditionally, the stone sheet is only made by the adhesive force of the bonding material 12. u and the backing plate 13 are joined, although the bonding material 12 has-fixed adhesion, but when the joining surfaces 111 and 131 of the stone sheet ^ and the back plate are both flat, the bonding material 12 is used for bonding It is easy to cause the sliding between the stone sheet u and the backing sheet 13 on the coating. The stone sheet 11 is not easy to be fixed and will cause a gap. Once there is a shear force (F) along the direction of the joint 13 1, the stone sheet 〖1 It is easy to peel and separate from the backing plate 13, and the combining ability of the two is not very good. Therefore, when these composite materials are subjected to mechanical grinding processing, cracks often occur, and the yield of the finished product is relatively low. [Summary of the Invention] In view of this, the main object of the present invention is to provide a composite material for strengthening stone material with a large effect of improving the adhesion and solidification, and a process for manufacturing the same. Yu Yan, the present invention provides a composite material of stone sheet, which comprises a stone sheet, a mesh material, a bonding material and a backing plate. The mesh material is cut to have the same area as the stone sheet and is laid on the stone sheet. At the back side, the bonding material is coated and soaked on the mesh, and a predetermined filler is added to the inside of the mesh. The backing plate has a bonding material that is bonded to the bonding material. Surface, the bonding surface is pre-pressed with a predetermined number of recesses: equi-concave ° 卩 has a predetermined depth and pore shape, and its recessed space can be filled with adhesive 200521302 material. After curing, the adhesive material can be fitted into the recess. The present invention provides the above-mentioned stone material mainly having the following steps: a process for manufacturing a thin plate composite reinforcing material, which includes: 0) preparing a stone material plate, 5 10 15 ⑺ cutting out a mesh material and a back plate having the same area as the stone material plate; (3). Cover the mesh on the back of the stone sheet; (4) · Apply and impregnate the adhesive on the mesh; (5) · Apply the backing sheet to the adhesive; ⑹. According to the characteristics of the bonding material, choose an appropriate temperature and force, and perform μ on the stone fascia and backing plate to completely harden the bonding material; (7) · Complete the finished composite reinforcing material. The main effect of this matter is to greatly increase the strength of the stone sheet and the backing plate and strengthen the combination of the two. ‘Through’ the core thickness and grinding of the ## composite reinforcement material in the later stage processing can effectively improve the finished product yield. [Embodiment] The above-mentioned and other technical internals, features, and effects of the present invention will be clearly understood in the following detailed description of preferred embodiments with reference to the drawings. Read more about FIG. 2 and FIG. 3. In a preferred embodiment, the stone sheet composite reinforcing material 20 of the present invention mainly includes—stone sheet 21, —net material 22 laid on the back of the stone sheet 21, and—coating. The bonding material 23 on the mesh material 22 and a backing plate 24 covered with the bonding material 23 and located on the stone sheet 2m, and then the structure of each layer of the composite reinforcing material 2 () of the present invention will be described in detail as follows. : 20 200521302 The stone slab 21 is a slab with a predetermined thickness. The operator can use natural stone slabs such as granite, marble, limestone, serpentine, fossils, quartz stone, or various artificial stone slabs such as roman granite and road ratio. The granite sheet 21 is cut to a thickness of not more than 0 mm in advance. ίο 15 The mesh material 22 is a mesh structure made of glass fiber material. Of course, the operator can also choose other materials to make the mesh material. The mesh material 22 is cut to have the same area and shape as the stone sheet 21. And laid on the back of the stone sheet 21, its role is to support the backbone, mouth, and mouth structure of the bonding material 23, thereby stably structuring the thickness of the middle layer of the bonding material 23. The main component of the bonding material 23 is an epoxy resin or a high-molecular resin, and an inorganic filler for improving adhesion is mixed and added inside the bonding material 23. The inorganic filler may be selected from clay, alumina, calcium carbonate, and silicon dioxide. , Mica, carbon black and other substances. The lining board 24 is adhesively covered on the bonding material 23, and the industry can see the demand of the mouth and mouth. '胄 Use a backing plate 24 that has light weight, high strength, or has related functions such as fire, waterproof, and shock resistance. Invented back view board ^ Material can be, metal plate such as fascia board, copper plate, steel plate, non-recording steel plate, or glass fiber resin board, strontium carbonate glass fiber board, laminated plastic board, thermoplastic board, wood board, pvc board , PE plate, plate,% plate, PP plate and other non-metal plates. Referring to FIG. 4 at the same time, one of the main features of the present invention is that a bonding surface 241 on which the backing plate 24 and the bonding material 23 are bonded has a plurality of recesses 242. Processing machines such as film machines or artificial hole removal methods are used to form the bonding surface. Each recess has a fixed depth and a hole shape of 20 200521302. The recessed space inside can be used for bonding materials 23 It is filled in, so that the adhesive material 23 can form a fitting structure to the recessed portion 242 after being dried and hardened. The size of the recessed portion 242 is not limited ', but the width or diameter of a single recessed portion 242 should not exceed one tenth of the total width of the backing plate 24, otherwise, if the number of recessed portions 242 is reduced too much, it will not be conducive to adhesion. In addition, the sphericity of the recesses 242 should not exceed one third of the thickness of the backing plate 24, otherwise it will affect the overall strength of the backing plate 24, and the distance (L) between the two recesses 242 is at most The recessed portion 242 is 2 to 5 times the maximum width or diameter. Referring to FIG. 3 and FIG. 4 again, in this embodiment, the concave portions 242 are arranged in a diamond shape, and each concave portion 242 is in the shape of a cylinder. Referring to FIG. 5, in a preferred embodiment, the concave portion 242 may be in the shape of a semi-circular sphere. Referring to FIG. 6, in a preferred embodiment, the recesses 242 are arranged in a rectangular checkerboard pattern, and each recess 242 ″ is in the shape of a quadrangular pillar. The above is the composite material of the stone sheet composite reinforcement 2 of the present invention. The structure and several examples of variable embodiments, and then the manufacturing process of the composite reinforcing material 20 of the present invention will be described. Referring to FIG. 7 and FIG. 8, the present invention mainly has the following steps: (1) First, prepare a (2) Prepare a glass fiber mesh material 22 and a backing plate 24. The backing plate 24 is selected from suitable materials according to functional requirements. The mesh material 22 and the backing plate 24 are first Cut to make the mesh 22 and the backing plate 24 have the same area and size as the stone sheet 21. (3) • Cover the mesh 22 on the back of the stone sheet 21. (4). In the mesh An adhesive material 23 is coated and impregnated on 22, and at this time, the adhesive 200521302 material 23 is a resin having fluidity. (5) · Then, the backing plate 24 is adhered to the adhesive material 23. (6) · Select an appropriate temperature and pressure according to the characteristics of the bonding material 23, and apply suitable pressure to the stone sheet 21 and the backing plate 24. The heavy object is hot-pressed, and after standing overnight, the bonding material 23 is completely hardened, and the fixing effect of the bonded stone sheet M and the backing plate 24 can be achieved. Person (7). The finished product of the composite reinforcing material 20 can be completed by the operator. The finished composite reinforcing material 20 is further subjected to post-grinding, polishing, and other surface processing actions to make products that can be used commercially. The above is an overview of the process for the composite material of stone sheet composite reinforcement of the present invention; The statement of the effects expected by the present invention is as follows ... The process of covering the mesh 22 by the bonding material 23 of the present invention is orderly. The coating amount of the bonding material 23 in each mesh can be controlled relatively evenly, which can solve the conventional problem. The entire surface is coated with depressions and voids, which leads to the loss of adhesiveness. Moreover, the mesh material 22 can reduce the fluidity of the adhesive material 23. In the case of lamination, the adhesive material 23 will not easily overflow, that is, No uneven distribution will occur, and the mesh material 22 can become the backbone structure of the bonding material 23, which helps to control the thickness of the intermediate layer of the stone sheet 21 and the backing plate 24 to be constant, so that the overall size In addition, the bonding material 23 of the present invention can increase the viscosity k of the resin and make it more viscous because the filler is added internally. In the process of pressing, the bonding material 23 is less likely to overflow and the stone sheet 21 is also less likely to overflow. It is not easy to slide, the thermal expansion coefficient of the inorganic filler is similar to that of the stone sheet 21 itself, and it is evenly dispersed in the resin, so that the resin is not easily deformed. The stone sheet 21 and the backing sheet 24 can be more 10 200521302! The properties are also more stable, and the fillers dispersed in the resin can disperse external forces and help provide composite reinforcement materials with impact resistance and toughness. 5 10 15 20 $ 月 月 ㈣ 反 24 has a surface Regular or irregular arrangement = 242 structure, the recessed 242 structure provides the backing plate%. When using the adhesive 23 and 5 ㈣ plate 21 for bonding, the contact area between the backing plate μ and the bonding material 23 increases, relatively Li ’s strength will also increase, and the bonding material ^ M to enter the recessed portion 242. When the backing plate 24 and the stone sheet 21 enter into the contracting and contracting business, the flowing bonding material 23 will be given from the space of the nearby recessed portion 242 first. Fill so The adhesive material 23 is less likely to spill to the outside. In addition, when the composite reinforcing material 20 receives a shear force (F) acting in the direction of the bonding surface 241 along the center of the backing plate 2, because the number of depressions 242 are distributed on the bonding surface 241 of the present invention, When forming a fitting structure with the hardened bonding material 23, the force will be dispersed or offset when it is transmitted to the recess 242, causing the shear force (F) to continue to be transmitted (as shown in Fig. 3 ^). The stone sheet 21 is more difficult to separate, and has better shear strength.疋 Therefore, the composite material of stone sheet composite reinforcement of the present invention and its process are mainly used to solve the lack of thicker 1G of traditional stone sheet composite materials and easy to be peeled off by force. The technical means used by the present invention is through glass fiber mesh. The material 22 fixes the thickness of the bonding material 23. In addition to the filler, the bonding material 23 can help to set the shape, and can improve the adhesion and increase the stability of the size. The recessed portion 242 of the backing plate 24 can increase the resin filling amount and adhesion. Area, to improve the situation where the stone sheet 21 and the backing plate 24 are easily separated by external forces, and it can make the composite reinforcing material 20 not easy to break when defending at the back section such as fixed thickness and grinding °, 11 200521302 can greatly improve the yield of finished materials. The composite stone manufacturing process is very simple, and the application range of the finished product is quite wide, such as furniture, professional, and interior decoration materials (such as ceiling floor $ backboard, etc.). It is a composite material system with high economic benefits, easy operation and excellent consistency.
