Abstract
Description
【発明の詳細な説明】 顆粒状マスターバッチおよびその製法に関する。[Detailed description of the invention] This invention relates to a granular masterbatch and its manufacturing method.
従来、無機顔料を高濃度に含有したポリオレフィンの着
色マスターバンチの製造は、無機顔料が粉体であること
からポリオレフィンパウダーへの分散が容易で且つ熱に
よる分解および逸散がなく、従って押出機等で比較的容
易にペレット化することができた。Conventionally, colored master bunches of polyolefin containing a high concentration of inorganic pigments have been produced using extruders, etc. because the inorganic pigments are powders, so they can be easily dispersed into polyolefin powders, and they do not decompose or dissipate due to heat. could be pelletized relatively easily.

軟化温度よりも低く、従って熱による逸散率が高くこの
方法は採用し得なかった。However, when producing a liquid composition, for example, a pellet-like masterbatch containing a perfume in polyolefin powder at a high concentration, the perfume is difficult to disperse into the polyolefin powder because it is liquid, and furthermore, when pelletizing with an extruder etc. However, this method could not be adopted because the boiling point of the fragrance was lower than the softening temperature of the polyolefin, and therefore the heat dissipation rate was high.

るいは射出成形時に発泡現象を生じ、満足な成形品を得
られないのが実情であった。As a method for solving the above problem, a method is known in which a fragrance is adsorbed onto an inorganic filler such as fine silica powder, and then blended with polyolefin powder and pelletized using an extruder or the like to obtain the target substance. However, when inorganic fillers such as silica are added to polyolefins, they generally reduce the transparency, gloss, etc. of the resulting molded products, and since inorganic fillers themselves contain a large amount of water, they cannot be used in extrusion or injection molding. The reality is that foaming sometimes occurs, making it impossible to obtain a satisfactory molded product.
一方、高い空隙率を有する多孔性ポリオレフィンペレッ
トに香料を多量に含有させる方法がある。On the other hand, there is a method in which a large amount of fragrance is contained in porous polyolefin pellets having a high porosity.
この方法により得られるマスターバッチはポリオレフイ

ラスチック成形品を得ることができる。The masterbatch obtained by this method can be blended with a polyolefin impeller and then extruded or injection molded, and it is possible to obtain an aromatic plastic molded article with less fragrance loss.
しかしながら、多孔性ポリオレフィンの製造工程および
香ＩＩ ン含有させる工程に特殊技術を要するためコス
ト高となることが避けられない。However, the production process of the porous polyolefin and the process of incorporating fragrance require special technology, which inevitably leads to high costs.
本発明者らは上記した実情に鑑み香料含有率が高く且つ
成形時に香料の逸散が少なく、安価な顆粒状マスターバ

系共重合体パウダーを使用することによりこの目的が達
成されることを見出して本発明に到達した。In view of the above-mentioned circumstances, the inventors of the present invention have deeply studied the production of an inexpensive granular masterbatch that has a high fragrance content and less fragrance loss during molding, and as a result, used a specific ethylene copolymer powder. The inventors have discovered that this object can be achieved by the following methods, and have arrived at the present invention.

フィンペ１ノットと容易にブレンドすることができる。According to the present invention, it is possible to provide a granular masterbatch containing a fragrance at a high concentration at a low cost, and since this masterbatch has a granular shape, it can be easily blended with general polyolefin pellets. Can be done.
また押出または射出成形等の熱成形時に香料が逸散する
ことも少なく、外観および物性の低下もなく芳香性のあ
るプラスチック製品を容易に提供することができる。Further, the fragrance is less likely to escape during thermoforming such as extrusion or injection molding, and it is possible to easily provide fragrant plastic products without deterioration of appearance and physical properties.

Materials other than ffi polyolefin powder can also be used. Further, as for fragrances, commonly available ones can be used, and there are no particular limitations on the fragrances. For example, natural fragrances such as lemon oil, lavender oil, and menthol, synthetic fragrances such as α-pinene, camphene, limonene, and methyl salicylate, and blended fragrances of these fragrances can be used.

VA/: Depends on the blending ratio of powder and fragrance and the amount of polyolefin powder added. That is, it is important to impregnate 100 parts by weight of EVA powder with at least 50 parts by weight, preferably at least 100 parts by weight, of fragrance to form a gel. If it is less than 50 parts by weight, it will not become gel-like, and even if polyolefin powder is added later, it will be difficult to form granules.

である。The amount of polyolefin powder to be added is preferably as small as possible so that the masterbatch has a high concentration of fragrance content under granular conditions. That is, usually 10 parts by weight of a gel composition consisting of EVA powder and fragrance.
It is preferable to add 0 parts by weight or more. If the amount of polyolefin powder added is less than 100 parts by weight, a sticky granular masterbatch will be produced, which is not preferable. At this time, this tendency can be slightly improved by adding a small amount of lubricant such as stearic acid or calcium stearate, but
It is preferable to add at least 100 parts by weight or more, preferably 150 parts by weight or more. However, when porous polyolefin powder is used, the bulk specific gravity is smaller than that of general polyolefin powder, so a granular masterbatch without stickiness can be obtained even with less than 100 parts by weight. In this case, the porous polyolefin powder is manufactured by Armak Co., Ltd. under the trade name Accurel.
Examples include powder. The fragrance content of the granular master hatch obtained by the above method is usually in the range of 5 to 60% when a general polyolefin powder is added and a porous polyolefin powder with a weight coefficient of 5 to 60% is added.

It is easy to blend because it is about the same size as general resin pellets.
