Description of the Related Art Generally, rubber products do not exhibit thermoplasticity because they are three-dimensional chains created by chemical crosslinking such as vulcanization. On the other hand, thermoplastic elastomers exhibit thermoplasticity when processed at high temperatures, and at the same time exhibit rubber elasticity and high strength at room temperatures. Structurally, it has a two-phase structure consisting of hard segments that correspond to rubber crosslinking points and soft segments that have rubber-like properties. During high-temperature processing, the frozen hard segments thaw, exhibiting thermoplasticity as a whole, and when the temperature returns to room temperature, the hard segments freeze again and act as crosslinking points. Since thermoplastic elastomers (TPE) were first introduced to the world about 20 years ago, various types of thermoplastic elastomers have been developed. Among these, olefinic TPEs are widely used because they are inexpensive and have relatively well-balanced properties.

とも限らず問題であった。As mentioned above, general rubber products do not exhibit thermoplasticity, and therefore, when sheets made of these products are bonded together, thermal welding is impossible. Therefore, a method of bonding with adhesive is used. In this case, it is necessary to use a large amount of adhesive, and it is not always possible to maintain adhesiveness over a long period of time, which is a problem.

As a result of various research and development efforts, they focused on the combined use of high-density polyethylene and low-density polyethylene as polyolefin resins and the addition of carbon black, and determined the amount of these to be mixed.

50 to 250 parts by weight of carbon black is added to 100 parts by weight of a blend obtained by mixing ~100 parts by weight and 30 to 150 parts by weight of low density polyethylene.

The Mooney viscosity (ML1+4, 100°C) is also not particularly specified, but a range of 30 to 80 is favorable for processing.

、規定範囲を越えるとゴム弾性が失われる。Although high-density polyethylene (HDPE) and low-density polyethylene (LDPE) are not particularly specified, it is preferable to select one having a relatively large melt index (MI). This is because when the MI becomes smaller, the adhesiveness tends to decrease slightly, although this is not a problem. The mixing amount of these HDPE and LDPE is
HDPE is 20 to 1 part by weight for 100 parts by weight of EPDM.
00 parts by weight and 30 to 150 parts by weight of LDPE. If the amount mixed is less than the specified range, the tensile strength will be low, and if it exceeds the specified range, the rubber elasticity will be lost.

00 parts by weight, it is necessary to set the amount to 50 to 250 parts by weight, and if the amount added is outside the specified range, it will not satisfy the JIS standard. In addition, carbon black has an average particle size of 60
A particle size of mμ or more is preferable, and if the particle size is 60 mμ or less,
It has strong reinforcing properties and reduces initial elongation.

For 100 parts by weight of a blend obtained by mixing 0 to 150 parts by weight and dynamically vulcanizing only the EPDM,
By adding 50 to 250 parts by weight of carbon black, it becomes possible to obtain a thermoplastic blend composition that has good thermal weldability and can satisfy JIS standards.
