[Industrial Application Field] The present invention relates to an antistatic agent for polyolefins. [Prior Art and Problems] Generally, polyolefin is a general term for polyethylene, polypropylene, etc., and is widely used as a molding material for films, molded products, fibers, etc. Although these materials usually have excellent electrical insulation properties, they tend to be charged and accumulate static electricity, which may cause various problems and disasters. For example, as is well known, these molded products are extremely susceptible to being contaminated by electrostatic charging, and dirt adheres firmly to them, causing a significant decrease in commercial value. Furthermore, ignition and explosion of flammable gas caused by discharge sparks is also a major problem. To solve these problems, antistatic agents have been proposed in the past, but they require long-lasting antistatic effects, good surface condition of molded products (no whitening phenomenon, no stickiness), and printing. It was not sufficient to simultaneously satisfy the requirements of good sex. [Means for Solving the Problems] The present inventors have solved the staining properties of these polyolefins and the possibility of combustible gas-induced explosions, sustained this effect, and produced polyolefins with good surface conditions and As a result of intensive studies to obtain an antistatic agent that provides a polyolefin composition with excellent printability, the present invention was completed by discovering that these can be satisfied when specific chemical substances are used in a specific ratio. That is, the present invention is based on the following general formula (In the formula, R 1 represents an alkyl group having 16 and 18 carbon atoms, and the alkyl group having 16 and 18 carbon atoms is 40/60 to 20/
Exist in a ratio of 80. ) and the following general formula R 2 OH (2) (wherein, R 2 represents an alkyl group having 16 and 18 carbon atoms, and the alkyl group having 16 and 18 carbon atoms is 40/60 to 20/
Exist in a ratio of 80. The present invention provides an antistatic agent for polyolefins, which is made of a higher alcohol represented by the following formula and has a weight ratio of alkyldiethanolamine (1) to higher alcohol (2) of 30/70 to 70/30. If the antistatic agent according to the present invention is mixed into a polyolefin resin, extremely satisfactory results can be obtained in terms of the sustainability of the antistatic effect, the surface condition of the molded product, and the printability. According to the present invention, it has been found that when an alkyl diethanolamine and a higher alcohol are used in combination, the influence of the alkyl chain length of each compound is unexpectedly large. Table 1 shows the influence of alkyl chain length when the ratio of alkyl diethanolamine to higher alcohol is 50:50, and the following trends were observed in Table 1. Area...Durability of antistatic effect Surface condition of defective molded product Printability with a tendency to stickiness Defective area...Durability of antistatic effect Good to slightly defective surface condition of molded product Printability with a tendency to stickiness Defective area...Duration of antistatic effect Good to slightly poor Surface condition of molded product Tendency to whitening Printability Poor area...Durability of antistatic effect Surface condition of good molded product Good printability Good In other words, the alkyl group of diethanolamine mentioned above
R 1 , alkyl group R 2 of higher alcohol has valley carbon number
16 and 18 must be between 40/60 and 20/80.

Next, the present invention will be explained with reference to Examples, but the present invention is not limited to these Examples. Examples/Comparative Examples 1 The antistatic agent shown in Table 2 was added to the synthetic resin and mixed and stirred for 1 minute using a Henschel mixer. After that, the injection molding machine (cylinder temperature 200
A plate (120 mm long, 60 mm wide, 3 mm thick) containing an antistatic agent was injection molded at ~250℃).
The antistatic effect, surface condition, and printability of the plate were examined after 30 days. The antistatic effect was determined by measuring the surface resistivity (Ω/□) (ASTM D 257). A value of 10 10 or less is good, a value of 10 11 to 10 13 is somewhat good, and a value of 10 14 or more is bad. The surface condition was visually determined. Printability was examined as follows. On the test player, horizontally.
Coat a square of 200 mm x 200 mm in height with polyamide ink, then print 100 squares of 1 mm in width x 1 mm in height.
Cut it with a cutter so that you can separate it into pieces. Semi-fixation was achieved by applying an adhesive tape thereon and then peeling it off (JIS K-5400 1979). 98% ink
If it remained above 97%, it was judged as good, and if it remained below 97%, it was judged as bad. Table 2 shows the results when 0.5 part of an antistatic agent (amine/alcohol = 50/50 (weight ratio)) was added to 100 parts of polypropylene (Mitsui Toatsu J-109G). The surface resistivity of the polypropylene plate without the addition of antistatic agent was 10 16 Ω/□ or more, and both the surface condition and printability were good.
