Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a resin composition.

[0002]

2. Description of the Related Art Synthetic resins have excellent properties such as light weight, easy processing, and the ability to design a base material according to the application. Material. For example, polyolefin resins are used in a wide range of applications such as packaging materials, building materials, automobile parts, household goods, agricultural materials, medical instruments, etc. due to their mechanical and chemical properties. These polyolefin resins are
Conventionally, it has been produced using a polymerization catalyst called a Ziegler catalyst. However, the resin obtained by the Ziegler catalyst has a wide molecular weight distribution, and it is difficult to control stereoregularity. Therefore, in recent years, by using a polymerization catalyst called a metallocene catalyst (single-site catalyst), a resin having a narrow molecular weight distribution and excellent stereoregularity has been obtained, and a narrow molecular weight distribution and improved stereoregularity have been obtained. Are expected to exhibit unique physical properties. Further, since the metallocene catalyst has excellent polymerization activity, it has become possible to carry out precise copolymerization of various monomers. Low molecular weight substances contained in conventional polyolefin resins are easily extracted by the solvent, causing problems in hygiene, causing stickiness and decreasing transparency, but by using a metallocene catalyst, These problems have been solved.

[0003] However, the drawback is that, due to the narrow molecular weight distribution, the flowability is low during processing, the processability is poor, and a phenomenon called melt fracture, in which the surface smoothness is impaired when molded at high speed, is also apparent. Has become. or,
One of the characteristics of the polyolefin resin is electrical insulation. Therefore, synthetic resins are frequently used as components of electric products. However, there is a problem that it is charged due to friction or the like because of too high electric insulation. The charged resin tends to be contaminated because it attracts surrounding dust and dust, and thus has a problem of impairing the appearance of the resin molded product. In addition, when an electronic product, for example, a precision device such as a computer, is charged, the circuit cannot operate normally. In addition, there is a problem due to electric shock. When electric shock occurs from the resin to the human body, it gives discomfort,
In addition, if there is a flammable substance in the surroundings, there is a possibility of causing an explosion accident.

[0004]

Therefore, in order to solve such a problem, a synthetic resin is usually treated to prevent electrification. The most popular method for this is to add an antistatic agent. Antistatic agents include
It can be broadly classified into a permanent antistatic agent that copolymerizes the antistatic unit in the molecule of the resin, and a kneading-type antistatic agent that is added when processing and molding the resin.

[0005] The kneading type antistatic agent bleeds out with the passage of time or separates from the surface of the resin due to friction or the like. For this reason, highly safe antistatic agents such as those approved as food additives have been used in resins used for food wraps and agricultural greenhouses. For example, glycerin esters, sorbitan esters, etc. However, since these compounds have a small molecular weight, they have a problem that they are easily volatilized, and the antistatic effect is difficult to maintain. This is particularly noticeable in the case of a thin material such as a film.

[0006] As a result of studying these problems, the present inventors have found that the use of polyglycerin fatty acid esters having a molecular weight larger than that of glycerin fatty acid esters improves the antistatic effect and the durability of the antistatic effect. And arrived at the present invention.

[0007]

That is, the present invention provides a resin substrate polymerized by a metallocene catalyst as a component (A), a fatty acid ester of polyglycerin having an average degree of polymerization of 2 or more, and a component (B). It is a resin composition containing a fatty acid amide or a fatty acid bisamide.

An mx 2 mm sheet was obtained. The surface of this sheet was observed to confirm the presence or absence of melt fracture.

：: The surface is smooth and glossy. Δ: Appears smooth but glossy. ×: Irregularities are observed on the surface. The wettability of the sheet was evaluated by measuring the contact angle with water. Furthermore, the antistatic property was evaluated by measuring the surface specific resistance at a temperature of 23 ° C. and a humidity of 60%.

[Table 3]

[0036]

[Table 4]

As can be seen from Tables 3 and 4, the sheet obtained from the composition of the present invention had a small contact angle, was easily wetted, and had good antistatic properties and surface condition.

[0038]

The effect of the present invention is to provide a resin composition which is excellent in antistatic effect and durability of antistatic effect.
