Abstract

PURPOSE:To manufacture a rubber product with a slide part low in the long- time slide resistance without lowering the physical property by a method wherein a rubber material is blended with a short fiber to be formed to a specified shape and then, a processing is done to expose the short fiber to a portion intended to form a slide part. CONSTITUTION:A rubber material such as FPDM and CR is blended with a short fiber about 1mm. long such as cellulose, nylon or polyester based ones to an extent of about 15-50PHR. Then, this blend undergoes an extrusion molding, a compression molding or the like to form a wiper blade material 10 with a specified shape comprising two wiper blades 1 and 2 with parts intended to form slide parts 1a and 2a, for example, connected together. Thereafter, after the vulcanization, the parts intended to form the slide parts 1a and 2a are cut off with a cutter 4 to produce wiper blades 1 and 2. Here, numerous short fibers 3 are exposed on the surface of the slide parts 1a and 2a.

For example, rubber products that are used for sliding parts that need to maintain low sliding resistance, such as weather strips used on sliding windshields of automobiles, are not limited to wiper blades. do not have.

パブレードを形成する方法であった。In conventional wiper blades, there are two methods for reducing the sliding resistance against the windshield. One is to perform a surface treatment such as halogen treatment or coating with urethane or fluorine paint on a wiper blade made of a rubber material.The other method is to apply disulfide to the wiper blade's rubber material. This method involved forming wiper blades by blending materials such as molybdenum, graphite, and Teflon resin powder.

Both methods had problems in that they had little effect on reducing dynamic resistance and had a large effect on reducing physical properties such as strength and elongation required for the wiper blade itself.

造方法にある。The gist of this invention is to provide a method for manufacturing a rubber product having a sliding part, in which short fibers are blended into a rubber material and formed into a predetermined shape, and then a process is performed to expose the short fibers in the area where the sliding part is to be formed. A method of manufacturing a rubber product having a sliding part is provided.

以下、図例に基づいてこの発明の一実施例を説明する。Hereinafter, one embodiment of the present invention will be described based on the illustrated example.

ことが望ましい。To explain the manufacturing method of the wiper blade of the example, first, EPDM, C
Short fibers of about 1 mm such as cellulose, nylon, or polyester are blended into a rubber material such as R (which may contain a polymer or a compound commonly used in rubber compounding). In addition, the blending amount of this short fiber is
If it is too small, the effect of reducing sliding resistance will be small, and if it is too large, it will become hard, so consideration must be taken to reduce the effect on the physical properties of the rubber material, such as by reducing the amount of carbon compounded. ”2 is preferably about 15 to 50 PHR. Further, when the rubber product to be manufactured is a wiper blade, it is desirable to use cellulose-based short fibers that have good water absorption and good wiping performance even with a small amount of rain.

, 2a are connected to form a wiper blade material 10 having a predetermined shape and consisting of two wiper blades 1 and 2 connected to each other. Note that 3 indicates short fibers.

The wiper blade 1.2 is manufactured by cutting the portion forming the wiper blade 1.2. At this time, a large number of short fibers 3 are exposed on the surfaces of the sliding parts 1a and 2a.

．． 2, since a large number of short fibers 3 are formed on the surfaces of the sliding parts 1a and 2a, the frictional resistance is low and the sliding resistance is reduced. Then, during use, the sliding part 1a,
Even if 2a wears out, new short fibers 3 are exposed, so low sliding resistance can be maintained. In addition, the physical properties of the wiper blade 1.2 itself are increased by blending short fibers 3 into the rubber material, which increases strength and slightly reduces elongation, but to reduce elongation, reduce the amount of carphone, etc. It can be dealt with by
Although the physical properties may be improved, they are not significantly degraded.

耐久テスト前後で比較すると第１表のようであった。Incidentally, Table 1 shows a comparison between the wiper blade 1 of the example subjected to halogen treatment and the conventional wiper blade 1 subjected to only halogen treatment before and after the durability test.

していることか解る。As can be seen from Table 1, before and after the durability test, the frictional resistance of the conventional product increased by twice as much, while that of the example increased by about 30%, and a comparison between the two after the durability test was made. It can be seen that the frictional resistance of the example is about 60% of that of the conventional example, indicating that the example maintains a low sliding resistance.

可能である。In the embodiment, the short fibers are exposed by cutting two wiper blades l and 2 with the cutter 4 and exposing the short fibers m3 to the parts where the sliding parts 1a and 2a are to be formed. However, it is of course possible to expose the short fibers 3 by cutting or grinding the portion where the sliding portion is to be formed, when each of the wiper blades 1.2 is formed individually.

。As described above, the present invention is manufactured by blending short fibers into a rubber material and forming it into a predetermined shape, and then performing a treatment to expose the short fibers in the area where the sliding portion is to be formed. A large number of short fibers are formed on the surface of the sliding part of the product, which lowers the frictional resistance and sliding resistance without reducing the physical properties such as strength and elongation of the rubber product. Even if the sliding part wears out during use, new short fibers are exposed, so the sliding resistance can be maintained at a low level for a long period of time.
