JPS6039298B2 - Composite polyolefin with antistatic function - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composite polyolefin having an antistatic function, and particularly to a composite polyolefin having an antistatic function suitable for use in pipes for household vacuum cleaners.

Conventionally, the pipes of household vacuum cleaners have not been provided with an antistatic function.

For this reason, there is a possibility that the dust that adheres immediately after blow molding will be carried directly to the home, and even if it is placed at the storefront of a retailer, the dust will adhere and have a negative impact on sales.Furthermore, on dry days While driving at home or after driving, I have found myself getting dust and feeling a slight electric shock on my fingertips. The present invention was devised to solve these conventional difficulties, and its purpose is to provide a composite polyolefin with antistatic function that can exhibit an antistatic effect for a long period of time immediately after production. be.

The present invention uses an antistatic agent polyoxyethylene alkylamine as a basic material, and mixes an appropriate amount of tallow ethylene oxide adduct thereto to impart an antistatic effect immediately after production.

The present invention will be described below based on an illustrated embodiment. Table 1: Addition of polyoxyethylene alkylamine (e.g. TS-2 manufactured by Kao Atlas Co., Ltd.) shown in Table 1 that has a long-lasting effect, and beef tallow ethylene oxide that is liquid and has an effect within a certain amount of time. In order to obtain a faster antistatic effect by combining the antistatic substances (for example, CA-2 manufactured by Lancrostad, UK), a composite composition as shown in Table 2 below was prepared.

Table 2 Total: 100 parts In addition, Figure 1 shows the long-term antistatic effect when only 0.5% of polyoxyethylene alkylamine was added as an antistatic agent without changing the composition ratio in Table 2 above. .

In FIG. 1, the horizontal axis D represents the number of days that have passed, and the vertical axis T represents the half-life. FIG. 1 shows the time required for the charging voltage to be reduced by half using an honest meter. As is clear from FIG. 1, a semi-permanent antistatic effect can be expected. Figure 2 shows polyoxyethylene alkylamine (TS
-2) with 0.5% of the material added together with 0.45% of polyoxyethylene alkylamine (TS-2) and 0.05% of beef tallow ethylene oxide adduct (CA-2) The half-life of the charged voltage at the initial stage after blow molding with the material was measured using an honest meter. In addition, the second
In the figure, axis D represents the number of days elapsed, vertical axis T represents the half-life, and graph A represents the characteristics of the material to which only TS-2 was added.
Graph B shows the characteristics of the material containing both TS-2 and CA-2. In Figure 2, even when only polyoxyethylene alkylamine (TS-2) is added, the antistatic effect appears after 4 days after molding.
In addition, the polyoxyethylene alkylamine (TS-2) according to this example and the tallow ethylene oxide adduct (CA-2), which has the same or slightly earlier effect, are also used.
It can be seen that when 2) was added in combination, the antistatic effect appeared on the first day after blow molding.

This effect has not been seen in conventional internally kneaded antistatic agents. In addition, as is clear from Figure 1, the antistatic effect of polyoxyethylene alkylamine (TS-2) is permanent, so when using this material for the pipes of household vacuum cleaners, it is difficult to remove dust. It can prevent adhesion and the feeling of electric shock on the greasy tip. In addition, it can prevent dust from adhering even when placed at a retail store, and it also has an antistatic effect after blow molding, which further improves moldability and effectively prevents dust from adhering immediately after molding. can be prevented. In the above examples, even if the compounding ratios in Table 2 are changed or the compounding materials are changed, the antistatic function of the same machine can be imparted by using polyolefin as the basic resin.

Further, this function can be imparted to the pipes of commercial vacuum cleaners, and the same function can be imparted to the blades of electric fans and ventilation fans whose basic resin is polyolefin.
The present invention has been described above based on preferred embodiments, but according to the present invention, the antistatic effect can be exhibited for a long period of time immediately after production.

[Brief explanation of drawings]

Figure 1 is a graph showing the long-lasting antistatic effect when only polyoxyethylene alkylamine is added, and Figure 2 is a graph showing the long-lasting antistatic effect when only polyoxyethylene alkylamine is added. It is a graph comparing the antistatic effect at the initial stage after production with a material to which an ethylene oxide adduct was added. D: Elapsed days, T: Half-life.
