- Comparative Example 1 in which the ratio of terminal amino groups to the amount of terminal carboxyl groups is far below 6 due to the amount of terminal amino groups being too small is the maximum weight (adhesiveness) of polyamide resin. Evaluation) was inferior to that of the example, and the fracture behavior (adhesion evaluation) was poor. With respect to the polyamide resin composition of Comparative Example 1, the average dispersed particle size was increased, and the alcohol resistance and impact resistance were reduced.
- Comparative Example 5 in which a diamine unit having a carbon number other than 9 to 13 was used, there was a problem in the residence stability of the polyamide resin and the alcohol resistance. With respect to the polyamide resin composition of Comparative Example 5, the average dispersed particle size was insufficient, and the hot water resistance, alcohol resistance and impact resistance were also lowered. [0218] Further, from the results in Table 2, the drug transport hoses of Examples 4 to 6 are excellent not only in the initial stage but also in the tensile elongation after LLC treatment, and the retention rate exceeds 70%, resulting in durability.
- the drug transport hoses of Comparative Examples 6 and 7 have comparatively less terminal amino groups in the semi-aromatic polyamide resin used, and the ratio of amino groups to carboxyl groups is too small. Since the drug transport hose of this example has too few amino groups to carboxyl groups, the drug transport hose of Comparative Example 10 uses a six-carbon diamamine as a component of semi-aromatic polyamide resin, and Since the drug transport hose of Example 11 uses a polyamide 6 resin composition, the tensile elongation after LLC treatment, the retention of bow I tension before and after LLC treatment, and low temperature impact resistance! This evaluation item is also inferior to the drug transport hose of the example.
- the semi-aromatic polyamide resin of the present invention a predetermined proportion or more of the terminal groups of the molecular chain are end-capped, the amount of terminal amino groups remaining is set in a specific range, and the amount of terminal amino groups is further reduced. Since the value obtained by dividing by the amount of terminal carboxyl group will exceed the predetermined value, it exhibits high retention stability, hot water resistance, and chemical resistance, and other resins that constitute polymer alloys Excellent adhesion and compatibility with the material.
- the polyamide resin composition containing this semi-aromatic polyamide resin exhibits high retention stability and hot water resistance, and excellent mechanical strength such as heat resistance, low water absorption, dimensional stability and creep resistance, In addition, it is possible to give a molded article having higher chemical resistance while exhibiting high impact resistance. Therefore, the polyamide resin composition containing the semi-aromatic polyamide resin of the present invention is suitable for molding materials such as industrial materials, industrial materials, and household products.
- the drug transport hose of the present invention exhibits excellent chemical resistance and good elongation, and further includes heat resistance, impact resistance, low water absorption, dimensional stability, creep resistance, etc. It is also excellent. Therefore, the drug transport hose of the present invention can be suitably used as a drug transport hose in various fields including the automotive parts field, the industrial material field, the industrial material field, and the household goods field.
- the joint for piping of the present invention significantly prevents fuel from passing through the wall surface and is excellent in impact resistance.
- it is possible to construct a piping system with high sealing performance by welding and joining with a resin hose and the like, and it can be suitably used particularly for a fuel pipe quick connector used for automobiles.
