た。Generally, vulcanized rubber with excellent permanent elongation, elasticity, and compression set is used for molded products such as packing, grommets, and tubes that require permanent elongation, elasticity, and compression set. Vulcanized rubber is made by blending raw rubber with sulfur and other vulcanizing agents and heating it to reduce the plasticity of the raw rubber and increase its tensile strength and elasticity. As described above, vulcanized rubber requires a vulcanization process to create an elastic body by causing a crosslinking reaction between the molecules of the raw rubber having plasticity. Vulcanization of the rubber is generally carried out by heating the compounded rubber in a mold with steam or hot water and applying pressure (110 to 170° C.). In this way, when vulcanized rubber is used for packing, grommets, tubes, etc., compared to ordinary synthetic resins, it requires a vulcanization process to create an elastic body. The manufacturing cost will be high. Therefore, in recent years, vinyl chloride-based TPE (thermoplastic elastomer) has come to be used instead of vulcanized rubber in order to reduce the manufacturing cost of molded products such as packings, grommets, and tubes. This vinyl chloride-based TPE does not require a vulcanization process unlike vulcanized rubber, so it has the advantage of being cheaper and easier to process than vulcanized rubber. Such conventional vinyl chloride thermoplastic elastomers are
Partially crosslinked PVC and highly polymerized PVC are mainly used as the resin component, and various plasticizers are added at 70 to 70 parts by weight per 100 parts by weight of the resin.
It was manufactured by mixing 100 parts by weight with a large amount of plasticizer, and adding appropriate amounts of various stabilizers and appropriate amounts of various fillers and processing aids.

Comparison results of 400% permanent elongation test, impact resilience test, and compression set test are shown for the vinyl chloride thermoplastic elastomer based on the example, EPDM (comparative example), and conventional vinyl chloride thermoplastic elastomer. It is shown in Table 1. The initial tensile test in Table 1 is conducted based on JISK6301. Each sample piece (20am x 20mm) is held at both ends and pulled until it breaks. It shows the applied force (tensile strength Ts) and the elongation rate (E, %) of each sample at that time. In addition, the aging test in Table 1 is based on each sample piece < 20 x 2
0 m) was left in air at 100°C for 120%, and then a tensile test was conducted to examine the state of deterioration of each sample piece. That is, each sample piece (20 cabinets x 2 orms
) in air at 100°C for 120 hours, hold both ends of each sample piece and pull it until it breaks, and calculate the force (Ts) applied to each sample when it breaks and the elongation rate (Ts) of each sample at that time. E residual) is expressed as a percentage (%) of the initial tensile test value. Furthermore, the oil resistance test in Table 1 was carried out using each sample piece (20m
20 + m) in oil at 70°C for 4 hours,
A tensile test is conducted to examine the oil resistance of each sample piece. That is, after immersing each sample piece (20 x 20 pieces) in oil at 70°C for 4 hours, hold both ends of each sample piece and pull it until it breaks, and calculate the force applied to each sample when it breaks (Ts residual ) and the elongation rate (E residual) of each sample at that time expressed as a percentage (%) of the initial tensile test value. In addition, the 400% permanent elongation test in Table 1 is based on JIS
Based on the permanent elongation test of K6301, all tests are performed using the remaining percentage after elongation by 400%, regardless of the actual elongation value. That is, each sample piece (20am x 20cm)
Hold both ends of the paper and stretch it by 400% (to 100 cm) and leave it as it is for 10 minutes. After that, loosen it slowly to prevent it from bouncing back, release both ends, and leave it in that state for 10 minutes. Thereafter, the elongation rate with respect to the original length (before stretching) of each sample is calculated. Therefore, the original length of each sample piece is 20 in this example.
Wm> is A and the length after release is B, then 400% permanent elongation α is calculated as α = (B-A n /A. The rebound resilience test in Table 1 is based on JIS K6301. It is a test of force and elasticity. In addition, the compression set test is based on JIS K6301, and measures the strain rate when the product is placed in a 70°C three atmosphere for 22 hours. Comparison in Table 1 The example is vulcanized rubber, which has excellent physical properties such as permanent elongation, elasticity, and compression set, and the present invention is also designed to approach the physical properties of this comparative example. Example (No. 4 to No. 11) and conventional example <Nα1
As is clear from the comparison with No. 3), according to the present invention, the property of 400% permanent elongation is close to 28% of the comparative example. Examples Ncl, Nα4, Nα6~N
a1l is smaller than 28% of the comparative example, and the example Nα5
is only 1% larger than the 28% of the comparative example, and even in Example NQ 2 and No. 3, it is 1% larger than the 28% of the comparative example.
It is only 1% to 12% larger. This has good elasticity and
This shows that it has strong resilience against excessive growth. This is also reflected in the initial tensile strength. That is, except for Example NQ 3, the elongation in the tensile test was 522% to 627%, which is a considerable elongation. On the other hand, the conventional example (Nal to NQ3) is 400%
The permanent elongation properties were all over 77%, which was significantly worse than that of the present examples (NQI to NQII). This is also reflected in the elongation rate in the initial tensile test. In other words, the elongation rate of the conventional example (Nα1 to NQ3) is 40
5% to 430% and Examples (NQI, 1llQ2, No4
- No. 11), there is a difference of more than 90%. Even when compared with Example Na 3, there is a difference of 40% to 65%. If this 400% permanent elongation property exceeds 50%,
It is no longer suitable as a material for packing, grommets, and tubes. As described above, compared to the conventional example, the present invention can improve the 400% permanent elongation property by 2 to 4 times. In addition, the rebound modulus in the rebound test was the same as that of the conventional example (N
al~Na5) is 27%~30%, while
Examples (N01 to Na 11 ) are 38% to 47%. That is, Examples (N01 to N0311
) has higher impact resilience than the conventional examples (N01 to N03), and has better impact resilience characteristics than the conventional examples (N01 to N03). Moreover, Examples (Collection 1 to NQ 11)
The impact resilience rate in the impact resilience test is 38% to 47%.
Therefore, almost the same impact resilience characteristics can be obtained as compared to the comparative example of 45%. As described above, the present invention can improve impact resilience characteristics as compared to the conventional example. As is clear from the comparison between the examples (N01 to Na 11 ) in Table 1 and the comparative example, according to the present invention, the compression set property in the compression set test was 35% of that of the comparative example.
The value is close to . The compression set rate of Example Na 8 was 33% and that of Comparative Example 3.
It is smaller than 5%. In addition, the compression set rates of the 9th and 10th samples were both 39%, which is higher than the 35% of the comparative example, but only 4% higher than the 35% of the comparative example, which is almost the same as the comparative example. It can be seen that the characteristics are acquired. Furthermore, the compression set rates of Examples NQ 1 to NQ7 and Example NcLll are 47% to 52%, which is 12% to 17% higher than the compression set rate of 35% of the comparative example, but the compression set rate of the conventional example (N0
The compression set rate is significantly improved compared to 62% to 63% of the compression set rate of 1 to Nα3). As described above, according to the present invention, the compression set characteristics can be improved compared to the conventional example.
