本発明は、研摩布紙の製造方法に関するものである。本

研摩布紙を提供することにある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a coated abrasive paper. The main object of the present invention is to reduce the cost of GT production by eliminating waste of abrasive grains deposited on the base material.Another object of the present invention is to reduce the cost of grinding by eliminating waste of abrasive grains deposited on the base material. Our purpose is to provide cloth paper.
従来の研摩布紙は、第１図に示すようにロール状に巻取
られた基材Ａの表面に接着剤Ｂをローラで均一に塗布し
、その接着剤Ｂ上へ砥粒Ｃを散布して帯状の研摩布紙素
材りとし、これを所定の形状に裁断して作っていた。Conventional coated abrasive paper is produced by uniformly applying adhesive B on the surface of a rolled base material A with a roller, and then scattering abrasive grains C onto the adhesive B, as shown in Figure 1. It was made by cutting a strip of abrasive cloth material into a predetermined shape.
回転式の研摩工具に貼着して使用される研摩布紙Ｅは、
主として円形状のものであり、帯状の研摩布紙素材りか

砥粒の無駄が多かった。とくに、ダイヤモンド砥粒や立
方晶窒化ホウ累砥粒等は極めて高価であり、使用されず
に晶棄される部分が多いほど研摩布紙のｌ１ｌＩＩ造コ
ストが高くつく不都合がある。Abrasive cloth E, which is used by attaching it to a rotary abrasive tool, is
The abrasive cloth paper E is mainly circular in shape, and when the abrasive cloth paper E of a desired shape (for example, circular shape) is cut from a band-shaped abrasive cloth paper material, there are parts to be discarded on the outside F and the inside G of the abrasive cloth paper. Since the abrasive grains in parts F and G cannot be reused, there was a lot of wasted abrasive grains. In particular, diamond abrasive grains, cubic boron nitride abrasive grains, and the like are extremely expensive, and the larger the portion that is unused and is discarded, the higher the production cost of the abrasive cloth paper becomes.

ｍ着されており、この研摩布紙Ｅを用いた研削加工にお
いては研削屑が砥粒の間ｔこ詰まって排出されないため
に重研削では発熱して研削焼けを生じるおそれがある。Furthermore, when observing the abrasive grain layer of the conventional coated abrasive paper E, it was found that the abrasive grains C were arranged randomly as shown in Figure 2. During grinding, grinding debris gets stuck between the abrasive grains and cannot be discharged, so heavy grinding may generate heat and cause grinding burn.

であった。Furthermore, in the conventional method, the IS agent is uniformly applied to the surface of the substrate using a roller, and the abrasive grains are sprinkled on top of it, so abrasive grain layers with different particle sizes or different abrasive grain layers of different leaf materials are adjacent to each other. It was extremely difficult to produce coated abrasive paper with a striped pattern.

郭線に沿って裁断する。Example 1 In this example, adhesive is screen printed on the surface of the adhesive, and abrasive grains are sprinkled onto the adhesive before it dries. As shown in Fig. 3, a base material 1 made of cloth, kraft paper, etc. is wound up on a roll, one end of the base material 1 is pulled out from the roll, and if necessary, it is shaped into a sheet of a predetermined size. The substrate is cut, and an adhesive such as glue or synthetic resin is applied with ink so that a folding agent layer 2 is formed on the surface of the base material 1 in a shape corresponding to the shape of the final product, the Ken-IN cloth paper 4. Screen printing is performed using Before the adhesive dries, abrasive grains 3 of a predetermined leaf material and grain size are sprinkled from above the adhesive layer 2 to form abrasive particles f6, and then the adhesive is dried. The scattered abrasive grains 3 are adhered to the base material 1 only in the adhesive layer 2, and are not adhered to the parts where the adhesive layer 2 is not formed. Therefore, the abrasive grains 3 sprayed onto the base material 1 on which the adhesive layer 2 is not formed are collected and used again. After the adhesive dries, a size coat adhesive is applied from above the abrasive layer 6 if necessary, and after the adhesive is sufficiently cured, the abrasive cloth paper 4 is cut along the outline.

となる。When the abrasive coated paper 4 manufactured by the above method is observed under magnification, it can be seen that there are two types of shapes of the adhesive R2. One is when the adhesive has a high viscosity.
The adhesive R2 is formed into a substantially rectangular shape within the mesh of the screen. (Fig. m4) The other one is when the viscosity of the adhesive is relatively low, and the adhesive layer penetrates not only into the mesh of the screen but also under the tension lines that make up the screen. It is formed to have a uniform thickness over the entire surface (not shown). In the former case, the adhesive layer 2 is not formed in the wire portion of the screen, and a large number of adhesive layers 2 having a substantially rectangular shape are formed with minute gaps corresponding to the thickness of the wire. becomes. When the abrasive grains 3 are sprinkled onto the adhesive layer 2, the abrasive grains 3 are attached and fixed to the adhesive layer 2 as shown in FIG. 6

If the viscosity of the adhesive is relatively low, the adhesive layer 2 is formed on the surface of the base material 1 to have a substantially uniform thickness.
The groove 5 described above is not formed.

Abrasive grain layer 19 is not formed.

能である。Example 2 This example is a further development of the previous example,
A paste is created by mixing abrasive grains into the adhesive, and the paste is screen printed onto the surface of the base material. Example 1
Mix abrasive grains with the same adhesive and stir thoroughly to make a paste. By using this paste as ink and screen printing in a shape corresponding to the shape of the sanding Ms cloth paper, an abrasive grain layer 16 consisting of adhesive Jfi 12 and abrasive grains 13 is formed, and the adhesive is sufficiently dried and cured. After that, the abrasive cloth paper 14 is cut along the outline. (FIG. 6) When the coated abrasive paper 14 produced by the above method is observed under magnification, it can be seen that there are two types of shapes of the abrasive grain layer 16 as in the first embodiment. One of them is when the viscosity of the adhesive is high, and the abrasive grain layer 16 is formed in a substantially rectangular shape within the mesh of the screen (FIG. 7). in this case,
This tendency increases as the grain size of the abrasive grains increases. The other one is
This is when the viscosity of the adhesive is relatively low, and the abrasive grain layer 16 penetrates not only into the mesh of the screen but also under the wires that make up the screen, and is formed to have an almost uniform thickness over the entire surface. has been done. In this case, the smaller the grain size of the abrasive grains, the higher the tendency. In the former case, abrasive grains [16] are not formed in the wire portion of the screen, and a large number of roughly rectangular abrasive grain layers 16 are formed with minute gaps corresponding to the thickness of the wire. That will happen. When grinding is performed using this coated abrasive paper, the grinding debris generated by the grinding escapes into the minute grooves 15 between the abrasive grain layers 16, is discharged from the grooves 15, and is discharged from the abrasive grain layers 16.
Prevent clogging in step 6. In the latter case where the viscosity of the adhesive is relatively low, the abrasive grains M16 are formed almost uniformly on the surface of the base material 11, so the grooves 15 described above are not formed. However, even in this case, it is possible to form the grooves 18 in the abrasive grain layer 19 as shown in FIG. 8 as described in the first embodiment.
この実施例２においては、とくに次に述べる研摩布紙の
製造が簡単に実施される。In this Example 2, the following production of the coated abrasive paper is particularly easy.
縞模様状に形成すること。To form a striped pattern.
状に形成すること。To form into a shape.
尚、上記実施例において使用されるスクリーンのメツシ
ュは６０〜４００メツシュ程度のＩ１羽囲のものである
が、この範囲のものに限定されなＶｌ。The mesh of the screen used in the above embodiment has an I1 circumference of about 60 to 400 meshes, but the Vl is not limited to this range.

節約の効果は大きく、製造コストの低減に役立つ。(1) Part 4 used as abrasive coated paper Since the abrasive grains are bonded together, the amount of abrasive grains used is significantly reduced compared to the conventional method, especially diamond abrasive grains and cubic boron nitride cumulative abrasive In the case of coated abrasive paper, which uses expensive IJ abrasive grains, the effect of saving abrasive grains is large and helps reduce manufacturing costs.
