Description

201020085 IX. Description of the invention: [Technical field to which the invention pertains] ‘Specially refers to a stone repairing reinforcement method. The present invention relates to a method for repairing stone materials. Micro-cracking method which can improve surface flatness and gloss quality 0 [Prior Art]

::Because of its special texture and color, stone has been favored by architects and consumers' and has occupied in the building materials market. The status of the world's stone minerals continues to develop, new varieties of stone _ come out, and promote architects and consumption A large number of stone materials are used in home building materials. Especially in recent years, marble and fossil stone have won the hearts of interior designers and consumers by virtue of their unique soft and soft colors and textures. The ups and downs of the use of the ups and downs gradually gradually changed the stone. While exploring the genesis and structure of the stone, it was found that different stone materials were different due to the forming reasons, and the composition and structure showed great differences, especially the fossil stone 'because it belongs to the sedimentary rock' itself structure It is loose, so that the polishing is repeated, and the table (4) will leave fine cracks and holes, which can not meet the quality requirements of the shiny and flat surface. At present, the stone industry for the cracks and holes of the stone #, its repair and strengthening: the law is the use of epoxy Resin, with semi-automatic glue-removing equipment or outdoor slabs, etc. Fill the cracks and holes of the stone, and then grind and polish the surface of the stone after the resin is hardened. Although the above-mentioned stone repair and strengthening method can fill the cracks and holes of most stone surfaces, there are still the following defects: Epoxy resin is a high-viscosity resin with high viscosity 彡__ 5 201020085 l_〇cps, the fluidity is so poor that it can not penetrate and fill 4 cracks and holes, although it can repair cracks or holes with large apertures, : The method repairs fine cracks and holes with smaller pore diameter on the stone. In addition, due to the poor wear resistance of the cured resin of the ring 2, when the thinner is added, the mechanical strength is lowered, and after grinding and polishing, it will be in the stone. Many fine cracks and holes are left on the surface, which may even cause the stone (4) domain to be removed, but instead create new micro-pits, which will damage the smoothness of the stone surface and make the existing repairing method have a relatively poor repair effect. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a micro crack and a hole that can reliably repair a stone and can The method further comprises the following steps: adding a flat gloss of the surface of the stone to fully exhibit the fine crack stone repairing method of the stone texture and color. The method for reinforcing the fine cracked stone according to the present invention comprises the following steps: (a) having an abrasive having a predetermined particle diameter Finely grinding the stone with fine cracks and holes; (b) washing the stone treated by the step (a) with water and drying; (e) preparing a repairing liquid which is composed of a nano ring containing a cerium sol The oxygen resin and a hardener are prepared by mixing in a predetermined ratio; (d) controlling the surface temperature of the stone to be 5 (rc~65°c), pouring the repair liquid on the surface of the stone, and uniformly applying the repair along the surface of the stone Liquid, so that the repair solution penetrates and fills the micro cracks and holes in the stone; (e) After a predetermined period of time, the stone is repaired a second time with the repair liquid prepared in step (c); 201020085 (1) The repairing liquid applied to the surface of the stone reaches a gelatinous (four) shape, and the repaired stone is placed at room temperature for a certain period of time, so that the repairing solution is completely hardened, which is favorable for subsequent processing procedures. And (g) for the later stages of the coarse stone surface patched, fine grinding and polishing process.

The invention has the beneficial effects that the micro-cracks and holes hidden under the surface of the stone can be exposed early by the rough grinding, minor repairing and fine grinding and polishing process, and the sol-containing epoxy resin is repaired. It can penetrate smoothly, which can effectively avoid the micro cracks and holes hidden inside the stone after fine grinding and polishing. In addition, the epoxy resin added with the cerium sol as a raw material of the repairing liquid can enhance the hardness and wear resistance of the cured epoxy resin after the gelation, and can solve the problem that the stone is damaged after the fine grinding and polishing, and Maintaining the operating temperature of the overall process is conducive to the fine cracks and pore expansion of the stone 'and can reduce the viscosity of the epoxy resin and increase its fluidity' can also promote the penetration of nano-epoxy resin into the fine cracks and holes in the stone. Therefore, through the repair and reinforcement method of the present invention, it is possible to surely fill the micro cracks and holes in the surface of the stone, and then coarsely grind and finely polish the surface of the stone to make the surface of the stone flat and bright, and to display clear lines and bright colors. The invention has a better repair and reinforcement effect. [Embodiment] The above and other technical contents, features and effects of the method for repairing and repairing the fine cracked stone of the present invention will be clearly understood from the following detailed description of a preferred embodiment with reference to the drawings. Referring to Fig. 1, a micro crack stone repairing and strengthening method of the present invention is preferably implemented. The embodiment of the present invention comprises the following steps: Step 101: rough grinding a stone having fine cracks and holes with an abrasive having a predetermined particle diameter. - where 'the stone may be a material selected from the group consisting of granite, marble, serpentine, fossil and limestone. And the stone is coarsely ground using an abrasive having a particle diameter selected from the group consisting of: 46 mesh, 60 mesh, 80 mesh, 12 mesh, 18 mesh, 22 〇 mesh, 240 mesh, 320 mesh, 400 mesh, and a combination of these. When used, depending on the particle size, it is used coarsely and finely. These mesh sizes are based on the standard Tyler mesh, and the micron Um) particle diameter corresponding to the mesh can be calculated by the following formula: 4900 / mesh = micro (" m) particle size value. For example, a 6-inch mesh abrasive' has a grinding particle size of about 248 am (14900/60). In step 102, the stone which has been coarsely ground in step 101 is washed with water and supplied for drying. Among them, the drying method should not be limited, and drying can be carried out by using a method selected from the group consisting of semi-automatic glue-removing equipment, drying with a fully automatic glue-removing equipment, and exposure to sunlight. Gas grabs baking, and one of these 'Wei 5. Here, the washed stone is placed on a semi-automatic glue-removing device for drying. In step 103, a repair liquid is prepared, which is prepared by mixing a nano-epoxy resin containing a bismuth sol-gel and a hardener in a predetermined ratio. Wherein the nano epoxy resin comprises a ruthenium sol and an epoxy resin, and by adding a ruthenium sol in the epoxy resin, the viscosity of the nano epoxide is higher than that of the epoxy resin on the market (viscosity up to llOOOcps~ 16000cpS) has a low viscosity of 201020085, and its viscosity can be reduced to several thousand cps and has high fluidity, since the cerium sol is formed by a plurality of sol-formed cerium oxide, and these - dioxide The particle size of Shixi is less than 20 nm, which is easy to penetrate into the fine cracks and holes of the stone with the epoxy resin, and can achieve the effect of reliably filling the micro cracks and holes. Preferably, the content of the cerium sol is from 3 wt% to 10 wt ° / Torr based on the total weight of the nano epoxy resin. More preferably, the content of the cerium sol is from 3 wt% to 6 wt% based on the total weight of the nano epoxy resin. If the content of bismuth sol is too low, the filling effect is limited; if the content of bismuth sol is too high, the surface hardness of the repaired stone is too high. When directly treated with fine grinding, it may not be possible to remove all hardened materials on the surface of the stone. The rough grinding treatment must be repeated, which in turn increases the time and cost of the grinding treatment. Therefore, the content of the cerium sol is preferably maintained at 3 wt% to 6 wt%. Wherein, the nano epoxy resin may be a commercially available nano epoxy resin containing a specific proportion of cerium sol (containing 20% by weight to 30% by weight/〇 of a cerium sol having a particle diameter of 20 nm or less), and then adding different amounts of pan Using a bisphenol A epoxy resin (ie, a resin that does not contain a cerium sol), a nano-epoxy resin (commonly referred to as A agent) of a different ratio of bismuth sol required for the desired product is prepared, and then the hardener (commonly referred to as B) The agent is mixed to form the repair solution. In this embodiment, the hardener is selected from the group consisting of amine compounds, and preferably, the hardener is a substance selected from the group consisting of triethylene tetramine (TETA). , tetraethylene pentamine (abbreviated as hydrazine), N-aminoethyl piperazine (N-aminoethyl piperazine, abbreviated as N-AEP), and a combination of these. When the repair solution is prepared, the epoxy equivalent of the epoxy resin used in the repairing solution is substantially 187, and the epoxy equivalent of the epoxy resin used for the hardening of the nano-rings of the repairing liquid is 187. Use the active hydrogen equivalent of the hardener Α24 How many grams of hardener phase is required to prepare the repair solution: 100 grams of epoxy resin required for the servant _ hardener activity i. When 詈m^ Wi xl0° 24.33 ie 187 reading 〇=13, according to which can calculate the 环氧1 gram of epoxy tree

13 grams of hardener phase is formulated. Among them, the active hydrazine refers to oxygen on the amine group which can react with the epoxy group epoxy group.

It is worth noting that the size, porosity and porosity of the stone to be repaired can also determine whether or not to add a thinner to the nano epoxy resin to match the commercially available nano epoxy resin (included 2 〇wt%~3〇wt% and particle size 20nm to T 石 谬 谬) and general-purpose epoxy tree gambling (10) 咖(10)a), 酉: a nano epoxide containing a predetermined concentration of cerium sol and a predetermined viscosity The resin (commonly referred to as agent A) is mixed with an amine hardener (commonly referred to as agent B) as the repair solution. Wherein the diluent is - a substance selected from the group consisting of: benzyl alcohol such as ~ akohoi), propylene carbonate (pr〇pylene carb〇nate), allyl epoxypropyl ether (ally) glycidyl ether' Referred to as AGE), butyl glycidyl ether (wet BGE), and combinations of these. When the diluent is added, the content of the diluent is less than 30 wt% based on the total weight of the nano epoxy resin. /. And preferably, the diluent is present in an amount of from 20 wt% to 30 wt%. As the content of the diluent is lower, the viscosity of the repairing liquid is higher, and the effect of infiltrating into the interior of the stone is relatively poor. If the content of the thinner 201020085 is higher, the mechanical strength of the hardened material is lower, and the hardness and wear resistance are higher. Poor, therefore, it is necessary to control the content of the diluent to an appropriate range, and secondly, it is preferred to maintain the content of the diluent at 20 wt% to 3 wt%. It should be added that the main purpose of adding thinner is to reduce the viscosity, thereby making it possible to dispense a repairing liquid with a relatively fine degree for the structure to be loose, but the surface has almost no visible cracks and the high water absorption rate of the hole is used. . However, the diluent is not an essential component of the nano epoxy resin, and even if the nano epoxy resin is not added with a diluent, it can be blended with the hardener to prepare the repair solution.

Step 1〇4 is to keep the surface temperature of the stone at 5 Gt~65t, pour the repair liquid on the surface of the stone, and smear the repair liquid along the surface of the stone with a trowel to make each part of the stone coated. The repair solution is placed on the cloth, and the repair liquid is applied to fill the micro cracks and holes in the stone. Then, the stone is sent to another open-type drying table by the same conveyor belt, and heated by the machine to maintain the operating temperature of the whole process, so that the stone is kept at a predetermined south temperature, which is beneficial to the micro crack of the stone. And the pores expand, and at the same time can increase the viscosity of the (10) low-nano (tetra) oxyresin' and increase its fluidity, making the repair liquid easier to penetrate into the interior of the stone. In step 105, the stone is heated by the open baking table for about 5 minutes and then the surface of the stone is reapplied with the repair liquid of (4) 1〇3 (four), and the stone is repaired for the second time, thereby ensuring the recovery in the repairing liquid. The methacrylate completely infiltrates all the fine cracks and holes. In the above manner, when the stone is heated in the semi-automatic material, the stone is placed on a drying table to be heated 5, : 11 201020085. When the stone is repaired in an outdoor board, the stone is allowed to stand in the sunlight for an exposure of €5 to 2G minutes, and then the second repair is performed. Step 106: Waiting for the repairing liquid applied to the surface of the stone to reach the hand (four) without being in a state of "four", and then 'the fixed stone is allowed to stand in an indoor environment at a temperature of C 32 C (ie, the temperature of the factory) 2 day. The above-mentioned gelatinization state refers to a state in which the resin is shaped and cannot flow, and the hand touches and deforms without touching the hand. Although the epoxy resin in the repair solution is gelatinized, it is unattainable (4), but (4) is not completely hardened. If the subsequent grinding and polishing treatment is performed at this time, the hardness of the hardened material may be low, and @ partial region may be removed. The surface is made more uneven, so the stone needs to be placed at room temperature for a while to completely harden it. When the value of the 疋t is repaired by semi-automatic glue-removing equipment and automatic glue-filling equipment, the semi-automatic glue-removing equipment includes 2 to 3 flat ovens and conveyor belts, and the dryers are For heating the stone, the conveyor belt is used for conveying the stone, can be dried when the stone passes through the first drying station, and after the passage, the first repair as described in step 1〇4 When the stone passes through the second drying station, the stone is first heated as described in Step 5 (5), and the stone is repaired a second time after passing through the second table. The fully automatic glue applicator includes i stacked tower dryers, j repair fluid automatic spray units, 1 repair fluid automatic coating unit and postcure use. Step 107 is to perform rough grinding, fine grinding and 12 201020085 polishing treatment on the surface of the repaired stone by rough grinding, fine grinding stone and polishing grindstone in the later stage, respectively, to remove the nano epoxy of the stone surface. The hardened resin, finally, gives the stone surface a clear texture and a bright color. ♦ It is worth mentioning that since the nano-epoxy resin containing cerium sol is added to the repairing liquid, the cerium sol is a nano-cerium oxide having a particle diameter of 20 nm or less, and can be effectively filled because of its small particle size. In the fine cracks and holes, the epoxy resin has excellent adhesion to the stone, and the Moh's Hardness value of the cerium oxide is as high as 7, which is resistant to the hardened material formed by the epoxy resin and the hardener. The hardened enamel formed by the relatively simple epoxy resin and hardener has high wear resistance and can grip the mineral grains without being easily removed during grinding. Therefore, the slate can be completely solved after the slate is polished and polished. The problem is to achieve a flat surface quality. "Specific Example 1" Black gold peak (a dark brown fossil) stone with fine cracks and holes, in turn, 7 kinds of commercially available marble grindstones with different particle sizes (including 46, 60, 120, 180, 220, 240) , and 320mesh abrasive) coarsely ground, washed with water, placed on a semi-automatic rubberizing device, and passed through a conveyor belt through a first open® drying station to completely dry the black gold stone and maintain its surface temperature. At 57 ~ 62 ° C. a nano epoxy resin (A agent) containing 6 wt% of a ruthenium sol having a particle diameter of less than 20 nm and tetraethylene pentamine (TEPA) (B agent) as a hardener The epoxy equivalent concentration of the nano epoxy resin=the appropriate ratio of the active hydrogen equivalent concentration of the hardener is sufficiently mixed into the repair liquid, and then poured on the surface of the black gold peak stone, and uniformly applied with a file back and forth to make the repair The nano-epoxy resin in the liquid penetrates and fills the stone. The black gold stone was then passed through a second open drying station and 13 201020085 to maintain its surface temperature at 57. (:~62. (:. Use a small amount of repair solution to apply the stone compared to the repair solution used for the first repair, and repeat the above-mentioned glue repair procedure to ensure that all exposed cracks and holes are completely nano-rings) The oxygen resin is filled up. Finally, when the black gold stone is delivered to the end by the conveyor belt, the nano epoxy resin applied to the surface of the repairing liquid reacts with the hardener to reach a gelatinized state. Jinfeng stone is first placed at room temperature (about i 8~32.〇) for two days, then placed in an automatic multi-grinding head, setting the direction of the stone travel speed axis to 56~63cm/min, and the grinding head moves back and forth. The speed (γ-axis direction) is о 60 m/min and is ground and polished in sequence with the following marble grindstones of different mesh sizes:

The surface of the black gold peak stone after grinding and polishing is smooth and smooth, no fine cracks and holes are observed, and the gloss of the stone surface is measured by gloss to show a gloss of up to 94. ❹ Among them, the test method of stone gloss is based on CNS7773 measurement, and the instrument used is the Sanwa Kenma IG-310 gloss meter. (Specific example 2) The type of stone to be repaired, the repairing liquid used, the second repairing and the subsequent grinding and polishing procedure are the same as (specific example 1), the difference is the black gold peak stone rough grinding pre-treatment, which is 8 A commercially available marble whetstone with different particle sizes (containing 46, 60, 120, 180, 22 〇, 24 〇, 32 〇 and _mesh abrasives) is ridden by coarse grinding, coarse (four) kiln, and then re-set. In the semi-automatic glue setting 14 201020085 ^ The method of the specific example of the black gold peak stone treated, the surface is still 'and no fine cracks and holes, when the method is used to measure the surface gloss of the slate At the time, it shows that its gloss is as high as 94. "With Zhao Case 3" /·,, Jinfeng stone rough grinding pre-treatment, the repair solution used and "with Zhao case -" are the same as the difference between the repair step and the subsequent grinding and polishing steps The specific example is after applying the repairing liquid, after the outdoor exposure is carried out, the hard money should be placed on the outer board of the black gold peak stone before the rough grinding, and the stone surface is removed; After the internal moisture of the stone, the surface of the stone is controlled, and the degree of the dish is 57. 61 c. Nano-epoxy resin (A agent) which is pre-formulated and contains _%, particle size smaller than other (10) material glue, and tetraethylene pentamine (TEpA) as a hardener (B agent) According to the calculated concentration of epoxy equivalent and active hydrogen equivalent concentration, determine the ratio of the amount 'and fully mix the repair solution' and pour the repair liquid on the black gold peak stone surface to smear with a sickle. After injecting the nano-epoxy resin into the stone and filling the stone for 20 knives, repeat the above-mentioned black gold peak stone repair procedure to ensure that the cracks and holes are completely filled with the nano-epoxy resin until the repair liquid applied to the surface of the stone The inner epoxy resin reacts with the hardener and reaches the gelatinized state, and then the stone is removed and sent to the factory for standing. The repaired black gold stone is allowed to stand at room temperature for two days, and then placed.
