改良した良品質のポリオレフィン樹脂組成物に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a polyolefin resin composition useful as a packaging film, etc. Specifically, by carrying out a specific treatment and blending fine powder silica into a polyolefin resin, This invention relates to a high-quality polyolefin resin composition that has improved dispersibility and blocking resistance while maintaining excellent transparency.

[従来技術および発明譚解決しようとする課題]従来か
らポリプロピレンフィルムは優れた透明性、剛性2強度
を生かして包装フィルムなどに用いられている。Background Art [Prior Art and Problems to be Solved by the Invention] Polypropylene films have traditionally been used for packaging films and the like, taking advantage of their excellent transparency, rigidity, and strength.
しかしながらフィルム間でブロッキングを起し易く、作
業性が損われるだけでなくフィルムの破損を生じ易い。However, blocking tends to occur between the films, which not only impairs workability but also tends to cause damage to the films.

はある程度改良されるものの、ポリプロピレンフィルム
の本来有していた透明性を損うという欠点があった。Therefore, anti-blocking agents such as finely divided silica are added to polypropylene films. Although the anti-blocking property is improved to some extent by adding this anti-blocking agent, there is a drawback that the inherent transparency of the polypropylene film is impaired.

、ラミネート性等の物性を悪化させたり、透明性に劣る
などの問題があり、十分満足しつるものは得られていな
いのが現状である。Various methods have been proposed for this purpose, but when finely divided silica is used as an anti-blocking agent, its dispersibility is poor due to the hydroxyl groups on the silica surface or the porosity of the surface. As a result, silica remains in the polypropylene as fish eyes, which causes problems such as deterioration of physical properties such as appearance, printability, lamination properties, and poor transparency, and it is currently not possible to obtain a fully satisfactory and durable product. be.

関してはむしろ悪化するという問題がある。That is, for example, a method has been proposed in which a master batch of finely powdered silica is prepared and melt-kneaded in two stages (Japanese Patent Laid-Open No. 58-61444). In this method, silica can be dispersed macroscopically in the film, but microscopically it is not completely dispersed, and as a result, although the anti-blocking properties of the film are improved, fish-eye, haze, etc. are rather worsened. There is a problem.

改善も不十分である。Furthermore, a composition made by mixing ultrafine hydrophobic silica powder and inorganic powder with polypropylene has been proposed (Japanese Patent Laid-Open No. 54
-145749). Although this composition maintains transparency, its anti-blocking properties are not necessarily good, and the anti-blocking agents must be pre-mixed, resulting in poor workability, and the improvement of fish eyes is also insufficient. It is.

を完成した。[Means for Solving the Problems] As a result of intensive research in order to solve these conventional problems, the present inventor has achieved the following by blending finely divided silica that has undergone a specific treatment into a polyolefin resin. It was discovered that a polyolefin resin composition with excellent various physical properties could be obtained as a result of improved dispersibility of silica, and the present invention was thus completed.

オレフィン樹脂組成物を提供するものである。That is, the present invention uses [B] 0.01 to 0.01 to 0.01 to 20% by weight of finely powdered silica having an average particle size of 1 to 10 μm and whose surface is coated with an organic substance at a ratio of 2 to 20% by weight, to [100 parts of AI polyolefin]. The object of the present invention is to provide a polyolefin resin composition containing 1.0 part by weight.

Copolymers with olefins such as butadiene are used. In addition to ethylene homopolymer, copolymers of ethylene and α-olefin having 3 to 10 carbon atoms are used as the polyethylene resin. The [A] acid component in the present invention is preferably a polypropylene resin.
また、本発明において[6]成分として用いる微粉シリ

ここで微粉シリカの平均粒径が1μm未満であるとブロ
ッキング防止効果が悪くなる°ため好ましくない。一方
、10μmを超えると透明性が悪くなるため好ましくな
い。If the average particle diameter of the finely divided silica is less than 1 μm, the anti-blocking effect will deteriorate, which is not preferable. On the other hand, if it exceeds 10 μm, transparency deteriorates, which is not preferable.
なお、微粉シリカの平均粒径としては2〜5μmのもの
が特に好ましい。Note that the average particle diameter of the finely divided silica is particularly preferably 2 to 5 μm.

挙げられる。Next, the organic substance used for coating the surface of fine silica powder is (1) - formula + 4 (CQOR) 2 [where M is from the periodic table! ! group metal, R is 6 carbon atoms
~23 alkyl groups are shown. ], (2) paraffin wax with a melting point of 60 to 90°C, and (3) polyolefin wax with a melting point of 80 to 140°C.

It represents a metal of Group 1I of the periodic table such as magnesium or barium, and R represents an alkyl group having 6 to 23 carbon atoms, preferably 11 to 21 carbon atoms. Specific examples of the metal soap represented by the above-mentioned formula include calcium stearate, magnesium laurate, zinc stearate, etc., with calcium stearate being particularly preferred.

い。If the coating amount is less than 2%, the dispersibility will be poor, and if it is too large, the physical properties of the silica as an anti-blocking agent will be impaired, which is not preferable. In addition, simply adding these organic substances instead of coating is not preferable because the dispersibility of the finely divided silica becomes poor and fish eyes increase.
