First, the sealant that is formed is not only affected by pressure and bending during seaming, but also subjected to the effects of high-temperature hot water and hot steam during retort sterilization, and canned beer and carbonated drinks during storage. In the case of general edible cans, the can is affected by external pressure due to the vacuum generated inside the can. Furthermore, the sealant is constantly exposed to extraction conditions due to its aqueous or oily contents.

When used as a sealant, a sealant with excellent hot water resistance, sealing performance, seaming performance, and mechanical properties is formed, and it has been shown at first glance that a sealing performance that lasts for a long period of time can be obtained.

To provide a sealing compound for can lids that can form an excellent sealant.
..., Constitution of the Invention According to the present invention, a can lid is characterized in that it contains a modified styrene-butadiene rubber containing 0.5 to 6% by weight of carboxyl, and 150% of a tackifier. A sealing con/gland is provided.

It has been discovered that compositions containing butadiene rubber, zinc oxide and tackifiers form sealants that are particularly suitable for sealing can lids and can bodies.

傾向がある。Sealants for can lids are required to have several properties different from those of ordinary rubber. That is, in addition to the general property of being compressible, this sealant also has the property of filling a narrow gap with the compressible flow M1 during seaming to seal the gap. It is required that tearing does not occur and that it has excellent creep resistance. These two properties are contradictory requirements, and satisfying these two requirements is a factor in ordinary crosslinked rubber, so the combination of uncrosslinked styrene-butadiene rubber (5TIR) and tackifier is essential. combination is used. However, with this compound, when the sealant is tightened, it can be squeezed out of the seam and mixed into the contents, or the sealant can deteriorate after long-term storage due to creep. Furthermore, there is a tendency for the sealant to absorb moisture and deteriorate its physical properties due to hot water.

張力が高すぎると、前述した充填密封性卵が低下する。According to the research conducted by the present inventors, the sealant is torn into small pieces at the seaming part, and the stiffness is squeezed out to the outside of the seaming part.
The phenomenon of leakage is closely related to the tensile strength and elongation of the sealant, and if the tensile strength and elongation are smaller than a certain standard, the above-mentioned squeeze ara) T! On the other hand, if the elongation of this sealant is too small or the tensile strength is too high, the above-mentioned filling and sealing properties will be reduced.

は得られかい。When carboxyl-modified SBR is used as a rubber component, and zinc oxide is not added, the improved oil resistance of the rubber itself due to carboxyl modification is reflected in the compound, making it more durable than conventional rubber compounds using SBR. This patent also improves oil resistance, but what about this patent? Is it possible to obtain the same performance as the one containing zinc chloride?

The results are shown in which the pile, tension (kq/l:m 2 ), and elongation (coefficient) are plotted on the vertical axis. According to these results, as shown in Table 1, the tensile strength of conventional SBR sealing compounds is approximately 2 to 5 kg/crn2, and the tensile strength of reverse vulcanized SBR rubber is generally 150 to 20 kg/crn2.
In the system used in the present invention, the tensile strength is on the order of 0 kg/z with 0.5 parts by weight of zinc oxide.
The tensile strength is on the order of 3 kg7rm, and the tensile strength increases as the blending amount increases, but the tensile strength is approximately 28 kg/cm.
It can be seen that saturation occurs on the order of .

ト性との組合せが得られることがわかる。In the conventional 5TJR sealing cone gland, even if zinc oxide is added, the tensile strength is low and there is a lot of squeeze-out into the can, and no effect of the addition is observed. The number of squeeze-outs decreases as the amount of zinc oxide increases, and squeeze-outs into the can are rarely observed when 1 part by weight of zinc oxide is added. Regarding impact sealing properties, as the amount of zinc oxide increases, the degree of vacuum decreases and the number of phases decreases, but if the amount is less than 90 parts by weight, the tensile strength is not very high, but the compressive modulus gradually increases and the potash elongation increases. As the vacuum pressure decreases, the number of cans increases. Thus, it can be seen that according to the present invention, a combination of high filling and sealing performance and one-squeeze-out properties can be obtained.

When used as a can, it also has the advantage of long-lasting pressure-tight sealing properties, and the tendency to absorb moisture when it comes into contact with hot water and the tendency to extract when it comes into contact with oily contents is also suppressed to a low level. There are advantages.

に適用することができる。Applications The sealing compound of the present invention is useful as a sealant for lining a variety of can bodies. For such a can body, a metal material (blank) such as black steel, tin-plated steel plate, tin-free steel, or A/S nium is cut to the required size and then soldered, glued, or welded. Three-piece cans that use a can body with a side lap seam or a hook seam, or formed from the aforementioned metal materials by drawing, drawing and ironing, or impact extrusion. Two-piece cans that use seamless can bodies are known, but the rubber composition of the present invention can be applied to the can body flange and can end (
It can be applied to form a sealant between can lids).
