，借助該黏結材12的黏結力，可將石材薄板u與背襯板 13兩者作結合固定，做成具有預定尺寸厚度的複合材1〇, 當此複合材10在製做完成以後，業者可對石材薄板u表面 進行後段機械加工或研磨製程，如此可得到最終產品的形 狀及平滑光澤表面。 以上製做技術雖然可將石材薄板u做成具有一定厚度 的複合材10結構，以利於對石材薄板u進行機械研磨拋光 等加工行為，然而上述複合材10結構卻會衍生下列缺失·· 1·整體厚度尺寸控制不易，該複合材1〇主要是讓石材 薄板11及背襯板13藉由黏結材12相互黏結在一起，雖然 石材薄板11與背襯板13的厚度是可以借助機械加工獲得控 制，然而該黏結材12是屬於流動性的黏稠液體，其厚度因 為塗佈量的多寡容易有不均情形發生，而且石材薄板丨丨及 背襯板13兩者在壓合時，黏結材12受壓容易自旁邊溢流 出來，當黏結材12在硬化後，黏結材12的體積反而會收 5 1224160 縮，因此製做出的複合材10成品常見有一邊較厚一邊較薄 的情形，如此對於後段研磨加工的平面精準度及尺寸定厚 工作都將變得困難。 2·結合強度不佳，石材薄板n是利用黏結材12與背襯 5 板13結合在一起，兩者的結合力相當重要，傳統只靠黏結 材12的黏力讓石材薄板u及背襯板13相接合，雖然黏結 材12具有一定黏性，但是該石材薄板11及背襯板13兩者 接合面111、131都是平面的情況下，使用黏結材12在作黏 〇時，塗佈上谷易造成石材薄板丨丨與背襯板丨3之間的滑動 1〇 ，石材薄板11不易固定且會造成空隙，一旦遇有沿著接合 面111、131方向的剪力（F)，石材薄板u與背襯板丨3容易 剝離分開，兩者結合能力並不十分良好，因此該等複合材 10在進行機械研磨加工行為時，往往會有龜裂情形產生， 成品的製作良率偏低。 15 【發明内容】

invention relates to a stone sheet, and more particularly to a stone sheet composite reinforcing material that can greatly enhance the effect of bonding and fixing, and a process therefor. [Prior art] As shown in FIG. 1, when manufacturing a general stone sheet composite material 10, first prepare a stone sheet 11 and apply a layer of resinous bonding material 12 to the back of the stone sheet. Cut a backing plate 13 of the same size as the stone sheet u, and then attach the backing sheet 13 to the back of the stone sheet u. With the adhesive force of the bonding material 12, the stone sheet u and the backing sheet 13 can be After the combination is fixed, a composite material 10 having a predetermined size and thickness is made. After the composite material 10 is completed, the manufacturer can perform a post-machining or grinding process on the surface of the stone sheet u to obtain the shape of the final product. And smooth glossy surface. Although the above manufacturing technology can make the stone sheet u into a composite material 10 structure with a certain thickness, which is conducive to mechanical processing such as mechanical grinding and polishing of the stone sheet u, the above composite material 10 structure will result in the following defects ... 1 It is not easy to control the overall thickness. The composite material 10 mainly allows the stone sheet 11 and the backing sheet 13 to be bonded to each other by the bonding material 12, although the thickness of the stone sheet 11 and the backing sheet 13 can be controlled by machining. However, the bonding material 12 is a fluid viscous liquid, and its thickness is prone to unevenness due to the amount of coating. Moreover, when the stone sheet 丨 丨 and the backing plate 13 are pressed together, the bonding material 12 receives The pressure is easy to overflow from the side. When the bonding material 12 is hardened, the volume of the bonding material 12 will shrink by 5 1224160. Therefore, the finished composite material 10 is often thicker and thinner. The plane accuracy and sizing of the post-grinding process will become difficult. 2. The bonding strength is not good. The stone sheet n is combined with the bonding material 12 and the backing 5 and the plate 13. The bonding force between the two is very important. Traditionally, the stone sheet u and the backing plate are only relying on the adhesive force of the bonding material 12. 13 bonding, although the bonding material 12 has a certain tack, but when the bonding surfaces 111 and 131 of the stone sheet 11 and the backing plate 13 are both flat, the bonding material 12 is used to coat the valley when bonding. It is easy to cause sliding between the stone sheet 丨 丨 and the backing sheet 丨 3. The stone sheet 11 is not easy to be fixed and will cause a gap. Once there is a shear force (F) along the joint surface 111, 131, the stone sheet u It is easy to peel and separate from the backing plate 3, and the binding ability of the two is not very good. Therefore, when the composite materials 10 are subjected to mechanical grinding processing, cracks may occur, and the production yield of the finished product is relatively low. 15 [Summary of the Invention] Therefore, the main object of the present invention is to provide a composite material for strengthening a stone sheet with a greatly improved bonding and fixing effect, and a process for manufacturing the same. Therefore, the present invention provides a composite material of a stone thin plate, which comprises a stone thin plate, a mesh, a bonding material and a backing plate. The mesh is cut into, and the stone thin plate has the same size and is laid on the stone. At the side of the sheet, 4 adhesive materials are coated and soaked on the mesh material, and a predetermined filler of female size is added inside; the backing plate has a bonding surface that is bonded to the adhesive material. A predetermined number of recesses are pre-formed on the bonding surface, and the recesses have a predetermined depth and pore shape. The recessed space can be filled with the bonding material. After the bonding material is cured, the recess can be fitted. The present invention is long: a process for the composite reinforcement material of the above-mentioned stone sheet, which mainly has the following steps: (1) preparing a stone sheet; 5 (2) cutting a mesh and a backing having the same size as the stone sheet (3) • Cover the mesh on the back of the stone sheet; (4) • Apply and impregnate the mesh on the mesh; (5) • Apply the backing sheet to the cement; (6). Select the appropriate temperature and pressure according to the characteristics of the bonding material, and heat-press the stone 10 sheet and the backing plate to completely harden the bonding material; (7). Finish the finished composite reinforcing material. The effect of the present invention is mainly to greatly enhance the strength of the combination of the stone sheet and the backing plate. Therefore, when the composite reinforcing material is subjected to the sizing and grinding of the post processing, the finished product can be effectively improved. rate. 15 [Embodiment] The foregoing and other technical contents, features, and effects of the present invention will be clearly understood in the detailed description of the preferred embodiment with reference to Figure 5 below. Referring to FIG. 2 and FIG. 3, in a preferred embodiment, the stone sheet composite reinforcing material 2020 of the present invention mainly includes a stone sheet 21, a mesh material 22 laid on the back of the stone 4 sheet 21, and a coating. The bonding material 23 disposed on the mesh material 22 and a backing plate 24 attached to the bonding material 23 and located on the back of the stone sheet 21, and then the structure of each layer of the composite reinforcing material 20 of the present invention will be described in detail as follows : Σ 7 1224160 > < The stone slab 21 is a slab with a predetermined thickness. Manufacturer :: slabs such as flower stone, marble, limestone, serpentine, chemical: use: Yingshi 4 can also use various artificial stone slabs such as Roman Gang The stone sheet 21 is cut to a thickness of 10 mm or less. 5 10 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. And laid on the back of the stone sheet 21, its role is to serve as a backbone structure to support the bonding material 23, thereby framing the bonding material 23—the thickness of the middle layer.主要 The main component of the bonding material 23 is an epoxy resin or a polymer resin, and an inorganic filler can be added to the bonding material 23 to improve the dimensional stability. The inorganic filler can be selected from clay, oxidized carbon, carbon dioxide, and dioxide. Any one or more of silicon, mica, carbon black and other substances. 15 20 The backing plate 24 is adhered and covered on the bonding material 23, and the industry can see the demand of the product function. 'Choose the backing plate M with light weight, high strength, or other relevant functions such as: waterproof, shockproof, etc. The material of this "inventory board" ^ I can choose I Lu plastic plate, steel plate, zinc ore steel plate, stainless steel plate, etc., or choose glass fiber resin plate, strontium carbonate glass fiber plate, ㈣ plastic plate, thermoplastic plate, wood plate , PVC board, PE board, pB board, PC board, second board and other non-metal boards. At the same time, one of the main special features of the present invention shown in Figure 4 is that the backing board 24 and the bonding material 23 are bonded together. 241 』Number of recesses 242. These recesses 242 are the industry's pre-deletion film machines, punching machines and other X-mechanisms, or use human health to press the method on the contact surface%. Each has a shape of depth and aperture. 8 1224160 shape, the recessed space inside can be filled by the bonding material 23, so that the bonding 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 single- The width or diameter of the recess 242 should not exceed the total width of the backing plate 24 Otherwise, if the number of recesses 242 is reduced too much, it will not be conducive to adhesion. In addition, the depth of the recesses 242 should not exceed one third of the thickness of the backing plate 24, or it will affect The overall strength of the backing plate 24, and the distance between the two recessed portions 242 is preferably 2 to 5 times the maximum width or diameter of the recessed portions 242. The basic principle is to not destroy the% strength of the backing plate. 10 Refer to Figure 3 again. As shown in FIG. 4, 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 It is a 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 structure of the stone sheet composite reinforcement material 20 of the present invention and a number of variable embodiments, and then the manufacturing process of the composite reinforcement material 2 () 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 stone sheet 21 of appropriate size. 2〇 (2) _ Prepare a glass fiber mesh 22 and a backing plate 24. The backing plate 24 is selected from appropriate materials according to functional requirements. The mesh 22 and the backing plate 24 are cut first. The mesh material 22 and the backing plate are made to have the same area and size as the stone sheet 21. (3) Cover the mesh material 22 on the back surface of the stone sheet 21. 9 1224160 (4) • Coating and impregnating a bonding material 23 on the mesh material 22 The material 23 is a resin with fluidity. (5) · Then attach the backing plate 24 to the bonding material. At this time, the bonding 5 (6). According to the characteristics of the bonding material 23, select an appropriate temperature and pressure. The heavy object is hot-pressed and left to stand overnight to 'harden the bond # 23 completely' to achieve the effect of bonding the stone sheet and the backing plate 24. 10 ⑺. After completing the finished product of the composite reinforcing material 20, the operator can perform surface processing such as post-grinding, polishing, etc. on the completed composite reinforcing material 20 to make a product for commercial use. 15 20 The above is an overview of the manufacturing process of the stone sheet composite reinforcement material of the present invention. Then, the effect expected of the present invention is described as follows: In the process of the adhesive material 23 covering the mesh material 22, each mesh hole The coating amount of the bonding material 23 can be relatively average and easy to control, which can solve the lack of conventional adhesiveness caused by the depression of the entire surface coating, and the lack of adhesiveness, and the net material 22 can _ low the fluidity of the bonding material 23, so During the pressing process, 'the bonding material 23 will not easily overflow, and there will be no uneven distribution, and the mesh material 22 can become the backbone structure of the bonding material 23', which helps control the stone sheet 21 and the back. The thickness of the intermediate layers of the two lining plates 24 is maintained constant, which makes the overall dimension stability more stable. In addition, the bonding material 23 of the present invention can increase the viscosity of the resin and make it more viscous because the internal filler is added. In the process of pressing, the bonding material M is less likely to overflow and the stone sheet 21 is less likely to slide. The inorganic filler The thermal expansion coefficient of the stone sheet 21 is similar, and it is evenly dispersed in the resin 10, which makes the resin difficult to deform. The stone sheet 21 and the backing sheet 24 can be more N-dimensional and more stable, and dispersed. The inorganic filler in the resin can disperse external forces and help provide composite reinforcing materials with characteristics such as impact resistance and toughness. 5 3 The surface of the f lining plate 24 of the present invention has a regular or irregular arrangement of the = 242 structure. These recessed 242 structures provide the backing plate 24 'backing when using the adhesive 23 and the stone sheet 21 for bonding. The contact area between the plate 24 and the bonding material 23 is increased, and the relative adhesion force is also increased, and the bonding material ^ can enter the recess 242. When the backing plate 24 and the stone sheet 21 enter the pressing industry, they are fluid. The bonding material 23 is first filled from the space of the recess 242 in the vicinity, so that the bonding material 23 cannot easily overflow to the outside. In addition, when the composite reinforcing material 20 is subjected to a shear force (F) along the direction of the bonding surface of the backing plate 24, the number of recesses ⑷ are distributed on the bonding surface 241 of the hair, and the bonding with the hardened When the material 23 forms a fitting structure, the force transmitted to the recessed portion 242 will be dispersed or canceled, causing the shear force 继续 to continue to be transmitted (as shown in item 3). Therefore, the backing plate 24 and the thin stone plate 21 of the present invention are difficult. Separated, has better shear strength.疋 Therefore, the stone thin plate composite reinforcing material of the present invention and its manufacturing process are mainly used to solve the problems of the conventional stone slab composite material 1G, such as the difficulty in setting the thickness and easy peeling, etc. The technical means used in the present invention is glass. The fiber mesh 22 fixes the thickness of the bonding material 23. In addition to the filler in the bonding material 23, it can improve the adhesion and increase the stability of the size. The recess 242 of the backing plate 24 can increase the resin filling. The amount and adhesion area can improve the situation that the thin sheet 21 and the backing plate 24 are easily separated by external forces. It can also make the 11 1224160 composite reinforcement material 20 difficult to break during post-processing such as fixed thickness and grinding, which can greatly improve the yield of the finished product. This composite stone manufacturing process is very simple, and the finished product has a wide range of applications, such as furniture, decorative panels, interior decoration materials (such as ceilings, flooring, wall panels, etc.) 'is a kind of high economic efficiency, easy operation and 5 practical Manufacturing method and structure of excellent composite material.
