The present invention relates to novel polyamide compositions.
The polyamide composition of the present invention has excellent moldability and can provide molded articles with excellent surface properties. Conventionally, a method is known in which a lubricant such as a bisamide or a metal salt of a higher fatty acid is blended with polyamide to improve surface properties such as gloss, transparency, and mold releasability of a molded article. However, in this method, it is difficult to uniformly adhere a sufficient amount of lubricant to the polyamide resin chips, and therefore the surface properties of the molded article cannot be improved to a sufficiently satisfactory level. In addition, in the case of injection molding, as molding becomes more automated and more efficient, polyamides with excellent moldability, such as good penetration into the screw of the molding machine and shorter plasticization times and smaller variations, are being developed. composition is required. That is, it is desired to develop a polyamide composition that has both good moldability and can provide a molded article with excellent surface properties. The present inventors have conducted extensive research in order to meet such demands. As a result, a polyamide composition in which a specific amount of a specific aliphatic alcohol as a third component is blended into a conventionally known composition consisting of a polyamide and a bisamide, due to the synergistic effect of the bisamide and the aliphatic alcohol, The present invention was completed based on the finding that not only the moldability was significantly improved, but also the surface characteristics of the resulting molded product could be significantly improved. That is, the present invention includes 100 parts by weight of polyamide, 0.005 to 1 part by weight of bisamides, and 0.005 to 0.2 parts by weight of a monohydric aliphatic alcohol having 12 or more carbon atoms.
parts by weight of the polyamide composition. The polyamide composition of the present invention has significantly improved bitability into the screw of an injection molding machine, and has a plasticity The conversion time and its dispersion are also significantly reduced.
Moreover, a molded article with improved surface properties such as gloss and transparency can be obtained. Examples of the polyamide used in the present invention include, but are not limited to, nylon 6, nylon 66, nylon 11, nylon 12, nylon 6.10, and nylon 6.12. Further, the form thereof is used in the form of a chip, but the shape and size are not particularly limited. However, it is usually cylindrical, with a diameter and height of 1.5 mm to 3.0 mm.
Alternatively, it is preferable to use a plate-shaped chip with length, width, and height of 1.5 mm to 3.0 mm. As the bisamides used in the present invention, any known bisamides conventionally blended into polyamide compositions are useful. For example, the following general formula:

Examples include 90N and Angelicol 90NR. The amount of these aliphatic alcohols used is 0.005 to 0.2 parts by weight, preferably 0.01 to 0.15 parts by weight, based on 100 parts by weight of the polyamide. If the amount used is less than the above-mentioned lower limit, the effects of the present invention cannot be obtained, and if it is more than the above-mentioned upper limit, molding troubles such as poor biting may occur when using a screw type molding machine. There are no particular restrictions on the method of blending bisamides and aliphatic alcohols into the polyamide, and any known blending method, for example, a blending method using a tumbler-type, V-type, or the like mixer, can be employed. In this case, the bisamide and aliphatic alcohol may be added to the polyamide chip at the same time, but the polyamide chip and the aliphatic alcohol are first mixed to wet the surface of the polyamide chip, and then the bisamide powder is attached. It will be more effective if you do so. In addition to bisamides and aliphatic alcohols, the polyamide composition of the present invention also contains known lubricants (for example, metal salts of higher fatty acids such as calcium stearate, magnesium stearate, barium stearate, and lithium stearate), and antistatic agents. ,
Appropriate amounts of flame retardants, colorants, crystal nucleating agents, fillers, reinforcing agents, heat resistant agents, weather resistant agents, etc. can also be blended. Examples of the molding method for the polyamide composition in the present invention include known molding methods such as extrusion molding, compression molding, and injection molding. There are no restrictions on the molded products that can be obtained, but examples include films, sheets, monofilaments, guts, gears, combs, and automobile parts. Examples are shown below. In addition, the No. of bisamides used in each example.
corresponds to the example No. of the bisamides mentioned above. Examples 1-4 Nylon 6 chips (about 2.5 mm diameter, length
After putting 100 parts by weight of 2.5 mm) into a V-type blender, add NG Ecol 200A [trade name, Shin Nippon Chemical Co., Ltd.
0.03 parts by weight of manufactured aliphatic alcohol was added and stirred for 15 minutes to uniformly adhere to the chip surface. Next, 0.1 part by weight of the bisamide fine powder listed in Table 1 was added and stirred for 15 minutes to obtain nylon 6 chips to which the additive was evenly adhered. Example 5 In place of NG Ecol 200A in Example 1, ANGIE Col 90N [trade name, Shin Nippon Chemical Co., Ltd.] was used.
Nylon 6 chips were obtained in the same manner as in Example 1 using 0.03 parts by weight of aliphatic alcohol produced by A. Comparative Example 1 Nylon 6 chips were obtained in the same manner as in Example 1, except that the NDG Ecol 200A in Example 1 was not used.

ばならないことを示す。[Table] From the results shown in Table 1, it is recognized that the polyamide composition of the present invention has a short plasticization time, little variation in plasticization time, and good mold releasability, and is extremely excellent in moldability. Examples 6 to 11 and Comparative Examples 4 to 7 To 100 parts by weight of nylon 6 chips (approximately 2.5 mm in diameter and 2.5 mm in length) with a relative viscosity of 3.5 (according to the same measurement method as shown in Example 1), a second A predetermined amount of each monohydric aliphatic alcohol shown in the table was added and stirred for 15 minutes to wet the chip surface. Next, a predetermined amount of fine powder of various bisamides shown in Table 2 was added and stirred for 15 minutes to obtain nylon 6 chips to which the additives were evenly adhered. Comparative Example 4 Nylon 6 chips were obtained in the same manner as in Example 6, except that the NDG Ecol 200A in Example 6 was not used. Comparative Examples 5 to 7 Bisamide No. in Example 6 was not used,
Further, nylon 6 chips were obtained in the same manner as in Example 6 except that the amount of NG Ecol 200A added was changed as shown in Table 2. Physical property test [2] Six nylon chips of Examples 6 to 11 and Comparative Examples 4 to 7 were tested using a 30 mmφ extruder.
It was extruded from a spinning nozzle with a diameter of 2.14 mmφ at 10°C, passed through a water bath at 10°C, and then wound up at a speed of 18 m/min.
After stretching 1.2 times at 230°C (total stretching ratio 4.5 times), it was heat-set in dry heat at 200°C at 1.0 times to obtain a 2000 denier monofilament. Each monofilament thus obtained was left in an atmosphere at 20° C. and 65% relative humidity for 7 days, and then subjected to measurement of strength and elongation and initial tensile resistance. In addition,
Tensile strength, tensile elongation and knot strength are measured according to JISL1070, and knot elongation is
Measured in accordance with JISL1070. In addition, the initial tensile resistance was measured according to JISL1073. The results are shown in Table 2. The transparency of the obtained monofilament and the biting property of the nylon 6 chips are also listed in Table 2. The transparency was determined by visually observing the monofilament wound around the bobbin, and ◎ indicates good, 〇 indicates fair, and × indicates poor. In addition, the biting property is determined based on the number of revolutions of the screw of the extruder to keep the discharge amount constant, and when ◎ is the reference number of revolutions of the screw, 〇 means that the number of revolutions of the screw is slightly lower than that of ◎. × indicates that the screw rotation speed must be increased considerably compared to ◎.
