Description
本発明は、エチレン重合体粒子組成物に関し、より詳細には焼結フィルタおよび粉体塗料の製造に好ましく用いることのできるエチレン重合体粒子組成物に関する。 The present invention relates to an ethylene polymer particle composition, and more particularly to an ethylene polymer particle composition that can be preferably used in the production of a sintered filter and a powder coating material.
従来、気体又は液体等から微細な粒子を分離する各種フィルタの材料として、オレフィン重合体粒子の焼結体が知られている。また、オレフィン重合体粒子は、粉体塗料の基体樹脂として使用されることもある。 Conventionally, a sintered body of olefin polymer particles is known as a material for various filters that separate fine particles from a gas or liquid. In addition, the olefin polymer particles may be used as a base resin for powder coating materials.
近年、フィルタへの要求性能の高度化に伴い、フィルタの孔径を微小かつ高精度に制御する必要性がますます強くなっている。このような要求に応えるべく、特許文献１には、エチレン重合体と帯電防止剤とを含むエチレン重合体組成物を焼結フィルタの材料として用いることにより、焼結成形金型に充填する際のエチレン重合体粒子の流動性を向上させ、以って成形ムラや欠陥が無く、超微細で均質なフィルタ孔径を有する焼結フィルタが得られることが開示されている。 In recent years, with the sophistication of the required performance of filters, there is an increasing need to control the pore diameter of filters with minute and high accuracy. In order to meet such demands, Patent Document 1 describes that an ethylene polymer composition containing an ethylene polymer and an antioxidant is used as a material for a sintering filter to fill a sintering molding die. It is disclosed that the fluidity of ethylene polymer particles is improved, and thus a sintered filter having an ultrafine and uniform filter pore size without molding unevenness and defects can be obtained.
しかしながら、特許文献１に記載の焼結フィルタを製造するためには、まず、帯電防止剤を溶媒に溶解させた後、得られた溶液中にエチレン重合体を含侵させる必要があるため、加工性の観点からさらなる改良の余地があった。 However, in order to produce the sintered filter described in Patent Document 1, it is necessary to first dissolve the antistatic agent in a solvent and then impregnate the obtained solution with an ethylene polymer. There was room for further improvement from a sexual point of view.
そこで本発明は、溶媒を用いることなく、流動性に優れ、かつ成形ムラおよび欠陥が抑制され、微細で均質なフィルタ孔径を有する焼結フィルタを製造することのできるエチレン重合体系材料を提供することを目的とする。さらに本発明は、成形ムラや欠陥が無く、微細で均質なフィルタ孔径を有する焼結フィルタ、および流動性に優れた粉体塗料を提供することを目的とする。 Therefore, the present invention provides an ethylene polymerization system material capable of producing a sintered filter having excellent fluidity, suppression of molding unevenness and defects, and a fine and homogeneous filter pore size without using a solvent.
