The present invention relates to glass fiber reinforced polyamide resin compositions. More specifically, the present invention relates to a glass fiber-reinforced polyamide resin composition that has few environmental stress cracks caused by metal halides and has excellent mechanical properties. Glass fiber-reinforced nylon, which is a blend of polyamide and glass fiber, is widely used as parts of automobiles and electrical products due to its toughness, electrical properties, and heat resistance. However, commonly used polyamides, such as nylon 6 obtained by ring-opening polymerization of ε-caprolactam and nylon 66 obtained by polycondensation reaction of hexamethylene diamine and adipic acid, are susceptible to environmental stress due to metal halides. It has the serious disadvantage of cracking. Calcium chloride, especially used as a road deicing agent,
Metallic zinc, etc., causes environmental stress cracks, which limits its use in the automotive parts field. Research has been conducted to improve this environmental stress cracking, and it is known that blending higher fatty acid polyamide with nylon 66 is effective. (Japanese Patent Publication No. 57-80448, 57-168940). As a result of intensive studies to further improve this problem, the present inventors found that when blending higher aliphatic polyamide [B] with nylon 66 [A], [A] and [B]
By specifying the molecular weight (relative solution viscosity) of the material and further reinforcing it with glass fibers, we surprisingly found that this improvement was greatly effective. Furthermore, it has been confirmed in a micrograph at a magnification of 14 times that the composition has a layered structure, and the present invention makes the layered structure effective in improving the environmental stress cracking. . That is, the present invention uses nylon 66 [A] 30-60
and 70 to 40 parts by weight of higher aliphatic polyamide [B] having (CH 2 /NHCO) of 6 to 11, and the relative viscosity of [A] is 4.0 to 5.0, and [A] and [ Glass fibers consisting of 90 to 40% by weight of a polyamide resin composition having a relative viscosity ratio of B] (relative viscosity of [A]/relative viscosity of [B]) of 1.50 to 2.50 and 10 to 60% by weight of glass fibers. The present invention relates to a reinforced polyamide resin composition. The glass fiber reinforced polyamide resin composition of the present invention is a resin composed of two types of aliphatic polyamides mixed with glass fibers, and the type of aliphatic polyamide used in the present invention is Ratio of number of groups to number of amide groups (CH 2 /NHCO)
It can be done with Nylon 66 [A] is a polyamide in which (CH 2 /NHCO) is 5. Higher aliphatic polyamide [B] is (CH 2 /
NHCO) is 6 to 11, such polyamides include nylon 11, nylon
12, nylon 69, nylon 610, nylon 612, nylon 613, or mixtures and copolymers thereof. If the ratio in [B] is 12 or more, [A]
The compatibility between and [B] is impaired, and the properties of the composition are impaired. The relative viscosity ratio of nylon 66 [A] and higher aliphatic polyamide [B] used in the present invention is 1.50 to
It is 2.50. If it is less than 1.50, the contribution of the metal halide to improving resistance to environmental stress cracking is insufficient, and if it exceeds 2.50, extrusion and moldability are poor and it is not practical. Further, the relative viscosity of nylon 66 [A] is 4.0 to 5.0. The relative viscosity here refers to the relative viscosity measured based on JISK-6810. The polyamide resin composition of the present invention is made of nylon 66
The viscosity ratio of [A] and higher aliphatic polyamide [B] is
Selected to be 1.50 to 2.50, nylon 66 [A]
It consists of 30 to 60 parts by weight and 70 to 40 parts by weight of polyamide [B]. If the amount of aliphatic polyamide [B] in the composition is less than 40 parts by weight, the improvement against environmental stress cracking caused by metal halides will not be sufficient; if it exceeds 70 parts by weight, nylon 66 [A] ) decreases the mechanical properties of The shape of the glass fiber used in the present invention is not particularly limited, and any shape from long fiber type to short fiber type can be used at the blending stage. The blending ratio of glass fiber can be arbitrarily selected depending on the use of the reinforced resin, but it is usually 10 to 60% by weight, preferably 25 to 45% by weight of glass fiber, based on the final glass fiber reinforced polyamide resin composition. % by weight. When the amount of glass fiber blended is less than 10% by weight, sufficient improvement in mechanical properties cannot be obtained. Furthermore, if the amount of glass fiber blended exceeds 60% by weight, the melt fluidity of the composition decreases, making extrusion and injection molding difficult. The composition of the present invention can be prepared by dry blending nylon 66 [A], higher aliphatic polyamide [B] and glass fibers, and then melt blending in an extruder such as a conventional single or twin screw extruder. You can get it. Another method is to melt and mix [A] and glass fiber, and [B] and glass fiber, respectively.
It can also be obtained by blending pelletized pellets using conventional methods and injection molding. Although the polyamide resin composition of the present invention has been described in detail above, other resin polymers, inorganic fillers, colorants, oxidative deterioration inhibitors, and heat stabilizers may be added to these compositions within a range that does not impair the purpose of the present invention. ,
Ultraviolet absorbers, antistatic agents, lubricants, plasticizers, flame retardants, etc. can be added depending on the purpose. In this way, the present invention is extremely distinctive. That is, previously published documents (JP-A-57-80448, JP-A-57-168940) indicate that nylon 66 [A] is blended with higher aliphatic polyamide [B]; There is no mention of the molecular weights (relative viscosities) of [A] and [B]. On the other hand, in the present invention, the molecular weights of [A] and [B] are further reduced to [A]
It has been discovered that the relative viscosity ratio of and [B] has a great effect on environmental stress cracking, and this is a completely new invention. Next, the present invention will be specifically explained using examples. Example 1 60 parts by weight of nylon 66 with a relative viscosity ηr of 4.78, and nylon with a relative viscosity ηr of 2.18, 2.76,
40 parts by weight of 610 were blended in the combinations shown in Table 1, and 50 parts by weight of commercially available short glass fibers (3 mm long chopped strand type) were added and blended in a tumbler type mixer. 50mm of this mixture
The mixture was melt-kneaded using a φ single-screw extruder to obtain a polyamide composition. The obtained glass fiber reinforced polyamide composition was molded into a test piece for measuring physical properties using an injection molding machine, and its resistance to environmental stress cracking was examined. The result is the first
Shown in the table. Comparative Example 1 Same as Example 1 except that nylon 66 with relative viscosity ηr of 2.79, 2.85, 3.80, 4.78, 5.20 and nylon 610 with relative viscosity ηr of 2.76, 2.18, 1.70 were blended in the combinations shown in Table 1. A glass fiber reinforced polyamide composition was obtained by this method and its environmental stress cracking resistance was investigated. The results are shown in Table 1.
