The present invention provides a polyamide resin composition that is electrically conductive and has good physical properties.More specifically, the present invention provides a polyamide resin composition that is conductive and has good physical properties. A conductive polyamide resin composition with good physical properties is obtained by uniformly kneading and dispersing a certain plasticizer and nitrile rubber. Plastics are originally insulating materials and have been widely applied in the field of electrical and electronic technology, but recently there has been an increase in attempts to impart electrical conductivity to plastics. This trend is an expression of the movement to add new value to materials by giving them new and more advanced functions, and we can expect them to be applied in various forms in electrical products in the near future. Against this background, attempts have already been made to make polyamide resin conductive.The method is to uniformly disperse conductive substances in polyamide resin and form conductive paths by interconnecting the conductive substances. can be obtained. However, in order to increase conductivity, a large amount of conductive substance is required, which considerably impairs the original excellent physical properties of polyamide.
The current situation is a major obstacle to the development of new applications. The inventors of the present invention have conducted extensive research in order to improve this drawback, and have discovered that a plasticizer and nitrile rubber that are compatible with polyamide are further added to the conventional composition, in which a conductive substance is simply added to polyamide resin. I was able to reach my goal. That is, a conductive polyamide composition to which a plasticizer and nitrile rubber are added can significantly improve impact strength and improve conductivity as compared to conventional compositions. Therefore, the amount of conductive material can be reduced by a corresponding amount, which is further advantageous in maintaining the original physical properties of the polyamide resin. The present invention will be specifically explained below. Polyamide resins that are the object of the present invention include homopolymers such as nylon 6, nylon 66, nylon 610, nylon 11, and nylon 12, as well as mixtures or copolymers of two or more of these. Any linear polymer having an amide group may be used. The conductive substances that can be used in the present invention include those in the form of fine particles and those in the form of fibers. Examples of conductive fine particles include carbon black such as acetylene black, conductive furnace black, conductive channel black, carbon fine particles such as graphite, and Al, Cu, Fe, Ni, Sn, Ti, Zn, etc., or brass. Fine alloy particles such as bronze can be used. Furthermore, the size of the conductive fine particles is 20
It is not more than μ, preferably not more than 5 μ. Further, carbon fibers and metal fibers can be used as the conductive fibers, and the diameter thereof is preferably 1 to 20 μm. The conductivity of the conductive polyamide resin composition in the present invention is 10 -8 Ω -1 cm -1 or more, and in order to satisfy this, at least 10 to 40% by weight of the conductive substance is required.
need to be added. For conductive fibers, the longer they are, the smaller the amount of addition required, but the conductivity is directional.
Although conductive fine particles must be added in larger amounts than fibers, they have the advantage of having less directionality. In addition, if the amount added is 40% by weight or more, the electrical conductivity will of course increase, but it is difficult to manufacture and process the polyamide resin composition, and even if it can be manufactured and processed, no improvement in physical properties can be expected. It is also unfavorable from this point of view. The plasticizer used in the present invention is a substance that has good compatibility with the polyamide resin and has a plasticizing effect.
For example, sulfonamide plasticizers such as benzenesulfonamide, N-butylbenzenesulfonamide, N-cyclohexylbenzenesulfonamide, para-toluenesulfonamide, and N-butylparatoluenesulfonamide, or phenols such as paraoxybenzoate octyl ester and pentadecylphenol. A plasticizer or the like is used. However, the plasticizer is not limited to these as long as it is compatible with the polyamide resin. The amount of plasticizer added necessary for the present invention is 5 to 20% by weight, and 5% by weight.
If it is less than 20% by weight, there will be little improvement in impact resistance, and if it exceeds 20% by weight, the mechanical strength, which is a characteristic of polyamide resin, will deteriorate.
It is not preferable because it impairs heat resistance, abrasion resistance, etc., and the plasticizer causes blooming. The amount of nitrile rubber used in the present invention is 20
% by weight or less. Further, the total amount of plasticizer and nitrile rubber added is 5 to 50% by weight of the whole, and although any ratio may be used, it is preferable that the ratio of plasticizer/nitrile rubber is 0.5 or more. Furthermore, in the present invention, in addition to the above-mentioned additives, lubricants, dispersants, mold release agents, heat resistant agents, weathering agents, flame retardants, etc. can be added within ranges that do not significantly impair conductivity and physical properties. In the present invention, a conductive substance is added to the polyamide resin.
As a method of kneading the plasticizer and nitrile rubber, any device that can uniformly disperse the plasticizer and nitrile rubber may be used.If kneading is difficult at once, kneading may be performed two or more times, but the result is a state in which the four components are uniformly dispersed. It is necessary to obtain a composition of Hereinafter, the effects of the present invention will be explained in detail with reference to Examples, but the present invention is not limited thereto. The volume resistivity shown in this example is ASTM-D.
-257 method, Izotsu impact strength is ASTM-D
- I followed the method of 256. For volume resistivity, a disk with a diameter of 100 mmφ and a thickness of 3.2 mm was used, and the disk was left in an atmosphere of 23° C. and 50% RH for 48 hours before measurement. In addition, the Izotsu impact strength is 63.5 in length.
A prismatic test piece with a side length of 12.7 mm was made with a specified notch and placed in an atmosphere of 23°C and 50% RH for 96°C.
After leaving it for a while, measurements were taken. Example 1 Nylon 6 pellets were blended with conductive furnace black (average particle size 20 mμ), N-butylbenzenesulfonamide, and powdered nitrile rubber (acrylonitrile content 40%) in a tumbler to give the composition shown in Table 1.
The mixture was uniformly kneaded using a vented twin-screw extruder set at 250°C, extruded into a gut shape, cooled with water, pelletized using a cutter, dried under reduced pressure, and then molded into test pieces. Table 1 shows the measurement results of volume resistivity and Izot impact strength for each composition.

果を表2に示す。[Table] As is clear from Table 1, a conductive composition with better Izod impact strength can be obtained than a conductive composition without the addition of a plasticizer and nitrile rubber. In addition, the volume resistivity decreases as the amount of plasticizer and nitrile rubber added increases, that is, the conductivity improves and the amount of conductive substance can be reduced to obtain the same conductivity. Example 2 Nylon 6, paraoxybenzoate octyl ester 17.65% by weight, nitrile rubber in the form of beans
After kneading 11.76% by weight in a 65 mmφ extruder and pelletizing it, 15% by weight of acetylene black was added to this composition and uniformly kneaded in a vented twin-screw extruder to obtain a test piece in the same manner as in Example 1. Ta. This composition contains 15% by weight of acetylene black (average particle size 50 mμ), 15% of paraoxybenzoate octyl ester.

cm, Izot impact strength was 15 Kg·cm/cm notch, indicating that the volume resistivity was lower and the impact strength was significantly superior compared to the composition without the addition of plasticizer and nitrile rubber. Example 3 Carbon fiber cut to 3 mm in nylon 66 (diameter

In addition, when a composition in which 30% by weight of aluminum powder was added to nylon 6 was similarly prepared and measured, the volume resistivity was 3.2×10 6 Ω・cm and the Izot impact strength was 1.5.
Kg・cm/cm notch, and it can be seen that the effects of the present invention are clearly exhibited.
