Description

  The present invention relates to a method for shaping a putty. The present invention also relates to a method of repairing a deformed portion generated on the surface of an object using a putty material.

  The method of repairing a deformed portion generated on the surface of a vehicle body using an putty specifically includes the following steps. That is, the process of peeling off the old paint film of the deformed part to be repaired, the feather edging process of processing the contour of the deformed part after removing the old paint film into a smooth taper shape, and applying the putty material to the deformed part of the feather edge processing Then, the step of shaping the putty with a spatula or the like so as to eliminate the deformation, and the step of polishing the putty surface after drying the putty material.

  However, in the conventional method, since skill is required for the putty shaping work, there are problems such as large variations in finish and poor work efficiency due to differences in the experience of the workers.

Therefore, a putty material is applied to the deformed portion of the plating surface, and before the putty material is dried, a scraper formed so as to be able to bend only in the direction of contact with the plating surface is used. A method has been proposed in which excess portions are scraped off and polished after the putty material is dried (see Patent Document 1).
See JP-A-10-113600

  However, according to the above-mentioned proposal, when scraping off the surplus portion of the putty material, the scraper is moved in a state of being in contact with the healthy plating surface, so that the healthy plating surface is easily damaged by the scraper. There are problems such as.

  The present invention has been made in view of the above circumstances, and can easily and efficiently perform putty shaping without damaging a healthy target surface regardless of the level of skill of each worker. It is intended to provide a putty shaping method and a repair method using a putty material.

  In order to solve the above problems, a putty shaping method according to the present invention includes a step of supplying a putty material to a target portion, a step of covering the putty material with a mesh sheet, and squeezing the upper surface of the mesh sheet with a spatula. It is characterized by comprising a step of shaping a putty material and a step of peeling off the mesh sheet before drying the putty material (Claim 1).

  On the other hand, the repair method using the putty material according to the present invention includes a step of supplying a putty material to a target portion, a step of covering the putty material with a mesh sheet, and squeezing the top surface of the mesh sheet with a spatula to attach the putty material. It comprises a step of shaping, a step of peeling off the mesh sheet before drying of the putty material, and a step of polishing the surface after drying of the putty material (claim 2).

  According to the present invention, by putting the upper surface of the mesh sheet with a spatula, the putty material moves under the mesh sheet, and the putty material is extended so that the target portion is filled without excess or deficiency. Excess putty material other than the putty material necessary to fill the entire target portion protrudes through the mesh of the mesh sheet to the upper surface and is scraped by the spatula. For this reason, even an unskilled person of putty shaping can perform putty shaping easily and reliably. Moreover, there is no worry of damaging a healthy surface other than the repair target part.

  As a preferred embodiment, in the step of polishing the surface of the putty material, polishing is performed while confirming the disappearance of the mesh pattern formed on the surface of the putty material by the mesh of the putty shaping sheet. (Claim 3). In this way, the degree of polishing can be made uniform over the entire surface of the putty material.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a process diagram of a repair method according to an embodiment of the present invention. The repair method according to the present embodiment includes a putty shaping method according to an embodiment of the present invention.

  The repair method according to the present embodiment includes a coating film peeling step → feather edging step → putty attaching step [FIG. 1 (a)] → putty shaping sheet arranging step [FIG. 1 (b)] → putty shaping step [FIG. (C)] → Putty shaping sheet peeling process [FIG. 1 (d)] → Guard tape attaching process [FIG. 1 (e)] → Putty surface polishing process [FIG. 1 (f)] → Guard tape peeling process → finishing process It is done in the order.

  Among the steps, the putty step to the polishing step are repeated for each putty material in the order of plating putty, intermediate putty, and polyester putty (poly putty) according to the type of putty material used.

  Hereinafter, each process will be described.

  The said coating film peeling process is a process of peeling the old coating film of the deformation | transformation part (dent and damaged part) of repair object surfaces, such as the vehicle body surface of a motor vehicle. A specific method may be the same as a conventionally known coating film peeling process.

  The feather edging step is a step of processing the contour of the deformed portion after the old coating film is peeled into a smooth taper. The specific method of the feather edging process may be the same as the conventionally known feather edging process.

  As shown in FIG. 1A, the putty applying step is a step of supplying the putty material 3 to the deformed portion 2 of the surface 1 to be repaired after the feather edging step and applying the putty material 3 using the spatula 4. It is. In this step, it is not necessary to perform shaping of the putty material 3, and it is sufficient to apply the putty material 3 by roughly extending it.

  As shown in FIG. 1B, the putty shaping sheet disposing step is a putty shaping sheet 6 made of a mesh sheet having fine mesh 5 so as to cover the entire surface of the putty material 3 after the putting step. Is a step of covering the surface 1 to be repaired. As the putty shaping sheet, a flexible sheet made of synthetic resin or the like is used so that the surface to be repaired is not damaged and the followability to the surface to be repaired in various shapes is also good. It is desirable to do. The degree of flexibility can be appropriately selected as necessary.

  The preferred size of the mesh 5 of the putty shaping sheet 6 is such that an extra putty material can smoothly protrude through the mesh 5 onto the upper surface of the putty shaping sheet 6 in the putty shaping process described below. Depending on whether the putty material to be used is a plated putty, an intermediate putty, or a polyester putty (poly putty), the preferred mesh size is different. In general, in the order of poly putty, intermediate putty, and plating putty, the putty material particles become larger, and the amount of putty material applied in the spatula stage increases, so the extra amount to be removed through the mesh of the putty shaping sheet The amount of putty is also increased. Therefore, from the viewpoint of efficiently discharging excess putty material from the mesh of the putty shaping sheet in the putty shaping process, it is desirable to use a putty shaping sheet having a mesh larger than that in the case of poly putty shaping. For example, each mesh size (area) of a putty shaping sheet for plating putty shaping is about 3 mm × 1.5 mm square, and each mesh size of a putty shaping sheet for poly putty shaping is 2 mm × 1.2 mm square. The size of each mesh of the putty shaping sheet for intermediate putty shaping can be about the middle of them.

  The putty shaping step is a step of shaping the putty material 3 by squeezing the upper surface of the putty shaping sheet 6 with a spatula 4 as shown in FIG. When the upper surface of the putty shaping sheet 6 is squeezed with a spatula, the putty material 3 moves under the putty shaping sheet 6 and the putty material 3 is extended so that the deformed portion 2 that is dented is filled without excess or deficiency. The extra putty material 7 other than the putty material necessary for filling the entire deformed portion 2 protrudes through the mesh 5 of the putty shaping sheet 6 and is guided to the surface of the putty shaping sheet 6. It is scraped by the moving spatula 4. For this reason, there is almost no step at the time of putty, and even an unskilled person of putty shaping work can perform putty shaping easily and reliably. In addition, since the top of the putty shaping sheet 6 is only ironed with the spatula 4 made of plastic or the like, there is no fear of damaging a healthy surface other than the repair target portion.

  The said putty shaping sheet peeling process is a process of peeling off the said putty shaping sheet 6 before the drying of the said putty material 3 after completion | finish of the said putty shaping process, as shown in FIG.1 (d). In the present embodiment, since a flexible sheet made of synthetic resin or the like is used as the putty shaping sheet 6, it can be easily peeled off.

  When the putty shaping sheet 6 is peeled off, a mesh pattern 8 corresponding to the mesh 5 of the putty shaping sheet 6 is inevitably formed on the surface of the putty material 3. The depth of the unevenness of the mesh pattern 8 is a size corresponding to the depth of the mesh 5 of the putty shaping sheet, that is, the thickness of the putty shaping sheet. The surface of the putty material 3 having the mesh pattern 8 is polished until the mesh pattern 8 disappears in a polishing process described later. From the viewpoint of improving the polishing efficiency and suppressing the generation amount of polishing debris, the mesh pattern In general, it is desirable that the putty shaping sheet 6 is thin so that the irregularities 8 are shallow. However, in the case of a plating putty, it is considered that when the unevenness of the mesh pattern 8 is large to a certain extent because the polishing is performed with an abrasive having a larger particle size than in the case of a poly putty, the biting of the abrasive is improved. It is desirable to use a thicker sheet than the shaped sheet. For example, the thickness of the putty shaping sheet for polyputty shaping can be about 0.55 mm, and the thickness of the putty shaping sheet for plating putty shaping can be about 1.04 mm.

  As shown in FIG. 1 (e), the guard tape adhering step is performed with a guard having an appropriate width on the surface of a healthy vehicle body so as to surround the shaped putty material 3 after the putty shaping sheet 6 is peeled off. This is a step of attaching the tape 9. By sticking the guard tape 9, it is possible to prevent sound vehicle body surface damage in the next polishing step.

  As shown in FIG. 1 (f), the polishing step is a step of polishing the surface of the putty material 3 using an abrasive 10 such as sandpaper after the putty material 3 is dried. As described above, in the putty shaping step, good putty shaping without a step difference is put in place, so that polishing can be started with an abrasive having at least the finest particle size than before. Therefore, the number of polishing steps can be reduced. Moreover, since the healthy vehicle body surface around the putty material 3 is covered and protected by the guard tape 9, even if the abrasive 10 is touched by mistake, the vehicle body surface is not damaged. Since the mesh pattern 8 is formed on the surface of the putty material 3, polishing is performed while confirming the disappearance of the mesh pattern 8, so that the degree of polishing is uniform over the entire surface of the putty material 3. Can be.

  Although not shown, the guard tape peeling step is a step of peeling off the guard tape 9 from the surface of the vehicle body after the polishing step.

  The finishing step is a step of performing a finishing operation such as painting after the guard tape 9 is peeled off, and is the same as a conventionally known method.

  According to the putty shaping method or repairing method according to the present embodiment including the steps as described above, the surface of the putty material 3 is covered with the putty shaping sheet 6 having the mesh 5, and the spatula 4 is ironed from above. Only, the shaping of the putty material 3 and the removal of the extra putty material 7 are performed satisfactorily. Therefore, regardless of the skill level of the putty shaping work using the spatula, any worker can easily, quickly and well finish the putty shaping. Moreover, since there is no worry of damaging a healthy surface other than the repair target part, it is more preferable.

  The scope of application of the present invention need not be limited to repairing the surface of a car body, and can be applied to any target surface to be constructed using putty, such as repairing the surface of a vending machine or repairing the surface of a bathtub. Needless to say.

It is process drawing of the repair method which concerns on one embodiment of this invention, (a) is putty forming process (b) is putty shaping sheet arrangement process, (c) is putty shaping process, (d) is putty shaping sheet. The peeling process, (e) shows the guard tape attaching process, and (f) shows the putty surface polishing process.
