善が切望されていた。2. Description of the Related Art As means for improving the strength of polyamide resin, it is known to incorporate a fibrous reinforcing material such as glass fiber.
Generally, a fiber reinforced polyamide resin composition is produced by mixing a polyamide resin and short fibers such as chopped strands and extruding the mixture with an extruder. However, this method cannot meet the demands for higher mechanical strength and the like because breakage of the fiber is inevitable during kneading in the extruder. On the other hand, in recent years, reinforcement of a polyamide resin with long fibers has been studied as a method for sufficiently bringing out the inherent properties of a fibrous reinforcing material to be compounded. Such a long fiber reinforced polyamide resin is obtained by, for example, a method of impregnating a continuous reinforcing fiber with an emulsion, solution or melt of the polyamide resin while pulling the continuous reinforcing fiber. However, in such a long fiber reinforced polyamide resin, nylon is used as a resin component.
When only 66 is used, the fluidity during molding is poor, and when molding is performed using such a material, the surface appearance of the molded product may be poor. Such a fluidity or surface appearance of a molded article is a problem peculiar to a polyamide resin reinforced with long fibers using nylon 66, and is a fiber reinforced polyamide resin and a polyamide reinforced with short fibers. With resin, such a problem does not substantially occur, and there is no practical problem. On the other hand, nylon 66 is excellent in mechanical strength, heat resistance, and the like, and in many cases, it is desired to use nylon 66 to take advantage of its features. In this way, polyamide resin reinforced with long fibers using nylon 66 is essentially excellent
R> Although it has mechanical strength, heat resistance, etc., its moldability and surface appearance are not always satisfactory, and improvements have been eagerly sought.

たものと推定される。Means for Solving the Problems The inventors of the present invention have made intensive studies to solve the above problems, and as a result, a polyamide resin reinforced with long fibers using both nylon 66 and nylon 6 as a polyamide resin has a high mechanical strength. The present invention was found to be excellent in heat resistance, heat resistance and the like, and also excellent in moldability and surface appearance, and completed the present invention. That is, the present invention (A)
A polyamide resin obtained by blending 99 to 1% by weight of nylon 66 component and 1 to 99% by weight of nylon 6 component is blended with (B) 5 to 80% by weight (in the composition) of a fibrous reinforcing material, The fibrous reinforcement has a fiber length of 3 mm or more in the composition, a long fiber reinforced polyamide resin composition, and injection molded using the long fiber reinforced polyamide resin composition, and the fibrous reinforcement has a length of 1 mm or more. And a molded product dispersed with a weight average fiber length. Hereinafter, the long fiber reinforced polyamide resin composition of the present invention will be described. The polyamide resin (A) as the base resin used in the present invention is nylon
It consists of 99-1% by weight of 66 components and 1-99% by weight of 6 components of nylon. As described above, even if a nylon 66 homopolymer is used, those which are not fiber-reinforced and those which are reinforced with short fibers do not cause problems in moldability and surface appearance, but only those reinforced with long fibers, Such a problem occurs. The cause is the high crystallization temperature of nylon 66 homopolymer,
It is presumed that the crystallization speed is high, and thus the fluidity during molding and the transferability to a mold deteriorate. In particular, in the case of plastics reinforced with long fibers, when plasticized for molding, entrainment of air during plasticization is severe, and a plasticized state with high porosity is formed in the molding machine due to cotton-like entanglement of long fibers. Therefore, it is considered that the fluidity and the surface appearance are further deteriorated. This was a problem specific to a polyamide resin reinforced with long fibers using a nylon 66 homopolymer.
On the other hand, the present invention is characterized in that, as described above, a polyamide resin obtained by blending a nylon 66 component and a nylon 6 component is used as the matrix polyamide resin. As a result, it is presumed that the crystallization temperature of the matrix can be lowered, the crystallization speed can be reduced, and the surface appearance can be improved by increasing the fluidity.

In the present invention, the polyamide resin (A) comprises 99 to 1% by weight of a nylon 66 component and 1 to 99% by weight of a nylon 6 component. When the content of nylon 66 exceeds 99% by weight, the fluidity and surface appearance are not sufficiently improved, and when the content of nylon 6 exceeds 99% by weight, heat resistance such as heat deformation temperature is insufficient. Become. The preferred compounding ratio in consideration of the balance of these properties is nylon 66
It is 95 to 10% by weight of the component / 5 to 90% by weight of the nylon 6 component, and particularly preferably 90 to 20% by weight of the nylon 66 component / 10 to 80% by weight of the nylon 6 component.

There is no particular limitation on the type of (B), and for example, any of glass fibers, carbon fibers, metal fibers, and resin fibers having a high melting point (high softening point) can be used. In the present invention, a reinforcing material selected from such fibers is blended in the composition at a length of 3 mm or more in an amount of 5 to 80% by weight (in the composition). If the compounding amount of the fibrous reinforcing material is less than 5% by weight, the reinforcing effect by the fiber is small, and if it exceeds 80% by weight, the processability in the preparation or molding of the composition becomes extremely poor, and the fiber amount increases. Almost no improvement in strength can be expected. Considering the balance between the reinforcing effect and processability, the preferred amount of the fiber is 20 to 70% by weight (in the composition),
Particularly preferably, it is 30 to 65% by weight (in the composition). In the present invention, an appropriate amount of short fibers in addition to the above-mentioned long fibers may be used as long as the total amount of the fibrous reinforcing material does not exceed 80% by weight.

However, in order to suppress fiber breakage, a production method in which a shearing force is as low as possible is generally preferable, and a production method by pultrusion is particularly preferable. It is preferably used.
Pultrusion molding is basically a process of impregnating a resin while pulling continuous reinforcing fibers, and a method of impregnating a resin through a fiber in an impregnation bath containing a resin emulsion, suspension, solution or melt. A method of spraying the powder on the fibers or passing the fibers through a tank containing the powder and attaching the resin powder to the fibers, then melting and impregnating the resin.Using an extruder etc. while passing the fibers through the crosshead die Any known method such as a method of supplying and impregnating a resin to a crosshead die can be used. In order to subject the resin composition thus obtained to injection molding, it is preferable to form a pellet having a length of 3 to 50 mm. In this case, the fibrous reinforcing material (B) has substantially the same length as the pellet. Thus, the pellets are arranged in parallel in the longitudinal direction.

特に有効である。In the resin composition of the present invention, one or two or more other thermoplastic resins can be used in combination as long as the object and effect thereof are not significantly impaired. Further, in order to impart desired properties according to the purpose, known substances generally added to the thermoplastic resin, for example, stabilizers such as antioxidants, heat stabilizers, ultraviolet absorbers, antistatic agents, flame retardants, flame retardants, and the like. It is also possible to further add a fuel aid, a coloring agent such as a dye or a pigment, a lubricant, a plasticizer, a crystallization accelerator, a crystal nucleating agent, and the like. Further, an appropriate amount of a plate-like or powder-like inorganic compound such as glass flake, mica, glass powder, glass beads, talc, clay, alumina, carbon black, wollastonite or whisker may be used in combination. In particular, as in the present invention, in those reinforced with long fibers, the presence of a lubricant is often required particularly for the flow of the molten resin in the flow of the pellets during plasticization or the uniform mixing of the fibers in many cases, and as a lubricant compound selected from metal salts of fatty acids lithium salts, and C 22 -C 32 fatty 0.01-3 wt% of the formulation is particularly effective.
