本発明はシリコーンゴムロールの製造方法、特には複写
機用の定着ロール、として有用とされるシリコーンゴム
ロールの製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a silicone rubber roll, particularly a method of manufacturing a silicone rubber roll useful as a fixing roll for a copying machine.

コーンゴムで被覆してなるものが常用されている。Fuser rolls for copying machines, especially electronic copying machines for copying onto plain paper, are usually constructed from a combination of a heating roll and a pressure roll, and this heating roll must be heat resistant. Therefore, those whose surfaces are coated with fluororesin or silicone rubber are commonly used.

いうことで不良品が出易いという欠点があった。Conventionally, this silicone rubber roll is made by inserting and fixing a metal shaft member into a mold, and then injecting a silicone rubber composition into the mold under pressure to surround the shaft with silicone rubber. It is made by heating and rolling silicone rubber, but in this case, the mold is a split mold, and the roll that is removed from the mold leaves crack marks on its surface.
This has the disadvantage that this surface then has to be mechanically reworked with VC, which also results in insufficient vulcanization of the crack and the formation of bubbles in the part, resulting in a defective product. The disadvantage was that it was easy to cause

させた。To explain this, the present inventors conducted various studies on examples of advantageous manufacturing methods for silicone rubber rolls, and as a result, first, the button was decided to use a cylindrical mold instead of a split mold.
Regarding this method of use, the liquid silicone rubber that forms the desired silicone rubber layer is charged into this cylindrical mold in advance, and then the shaft is charged into this cylindrical mold and fixed. We confirmed that by heating the silicone rubber layer if necessary and removing the cured product from the cylindrical mold, it was possible to easily obtain a silicone rubber roll with no crack marks. Completed the invention.

囲のものとすることが好ましい。The liquid silicone rubber that can be used in the method of the present invention may be either a thermosetting type or a room temperature vulcanization type as long as it is in a liquid state. Because this is vulcanization in a vacuum vessel, and because the target material is ``-'' and air bubbles should be avoided, it is possible to use a vulcanization method that does not generate by-products due to the reaction. It is preferable to use an addition reaction between the Si - From the viewpoint of ease of operation, it is preferable to have a range of 5+000 to 1+ooo, ooocS.

性が与λ−られる。On the other hand, the cylindrical mold used in the method of the present invention is made of metal such as iron or aluminum, and its size is determined by the shape and size of the intended silicone rubber roll. It is necessary to provide a shaft fixing device for centering the shaft inserted into the
By making this shaft fixture movable up and down, it becomes easier to insert the shaft, and by extruding it onto the shaft after the silicone rubber has hardened, it has the advantage of making it easier to take out the silicone comb roll as a product. It will be done.

に商品化されるという有利性が与えられる。Figure 1 shows a conventional method for manufacturing silicone rubber rolls. In this case, an aluminum shaft 2 is locked in a split mold consisting of molds 1 and 1', and an injection port 3 is inserted into the shaft 2. Silicone rubber is injected under pressure,
This is the hardened silicone rubber layer 4 and 1 on the surface of the shaft 2.
However, as mentioned above, the silicone rubber roll obtained by this method suffers from poor curing near the cracks in the split mold, the formation of air bubbles, and the marks of the cracks. There is a disadvantage of staying. FIGS. 2 and 3 show the method of the present invention, and the bottom 12 of the bottomed cylindrical mold 11 has a ring part that can move up and down and is connected to a shaft fixture 13 for centering. 14 are provided. As shown in FIG. 2, the method of the present invention is carried out in a state in which the Shinto 14 is pressed against the bottom part 12 and the L-C shaft fixture 13 is held in the middle part of the mold 11 using liquid silicone rubber. After injecting 15 to the vicinity of the shaft fixing tool 13, the shaft 1 is suspended from the lid 16.
7 and insert this shaft 17 into the mold] 7, and attach this to the shaft fixture 13. Next, this shaft 17 is further pushed down to lower the ring part 14, and the lid body 1 is lowered.
6) When the upper end of the mold 11 is reached, the shaft 17 will be completely surrounded by liquid silicone rubber as shown in FIG. 3, so the silicone rubber can be cured in this state. After this curing is completed, the silicone rubber roll obtained by this method can be easily taken out by pushing the ring part 14 up and returning it to the negative position shown in FIG. Since this mold is cylindrical, there are no cracks like those found in conventional methods, and the entire surface is homogeneous, and there are no cracks in the mold yet. Since there are no curing defects or bubbles, this product has the advantage of being immediately commercialized.

After pouring a homogeneous mixture of 3,500 parts of RTV rubber (manufactured by Shin-Etsu Chemical Co., Ltd., trade name) and 25 parts of curing catalyst RM [manufactured by the same company, trade name], aluminum with a diameter of 40 mm and a length of 300 mm was poured into the mixture. A manufactured shaft was inserted, fixed to a shaft fixture and pushed up, and the shaft was immersed in liquid silicone rubber and left for 72 hours. The surface of the shaft was coated with a layer of cured silicone rubber with a thickness of 5 mm. At this point, the two levers for pushing the continuous parts were pulled out, and a silicone rubber roll was obtained.
