が多く良品は得られない。421 Conventional technology Conventional method for manufacturing synthetic resin pellets, i.e., mask patches containing high concentrations of various additive-containing microcapsules ■ Mask batches manufactured by the tri-blend method have a mixing ratio of additive-containing microcapsules of at most 10 ~ It is 20%. If synthetic resin powder is used instead of synthetic resin pellets, a mixing ratio of about 80% can be obtained, but these mask batches alone or mixed with synthetic resin pellets can also be used to make a film using a film-making machine, for example. When produced, the resulting film has poor dispersion of the encapsulated microcapsules in the resin and has many defects such as fish eyes and flow marks, making it difficult to obtain a good product.

Pellets of X4 square size were obtained. This pellet 6s was mixed with 95 parts of polyethylene resin using Pre-Goo and molded into a toothbrush handle using an injection molding machine.The microcapsules in this handle were extremely homogeneously dispersed and had a Para-fragrance aroma, and its fragrance retention period was 10 minutes at room temperature.

This sheet was a homogeneous sheet with no fisheye marks, and when water vapor was sprayed onto it, no condensation occurred and no water was produced. This anti-fog effect can withstand repeated wiping1.
Has been used for many years. This sheet contains 4% anti-fog agent, but it is made by extrusion molding by directly blending 4% anti-fog agent into soft PVC compound, and the sheet has no condensation and has anti-fog properties for the first few times. However, after that, the antifogging properties decreased dramatically with wiping, and the antifogging effect was no longer exhibited after one week.

た。Example 5 80 parts of silica microcapsules containing 50% Parafragrance, 10 parts of polyethylene, and 10 parts of zinc stearate were mixed in a blender, and the mixture was molded into a toothbrush handle using an injection molding machine. However, injection molding was not possible due to the small amount of polyethylene.
上記配合物５部に更にポリエチレン９５部を加ヘプレン
ダーで混合し、射出成形機で歯ブラシの柄を成形した。Further, 95 parts of polyethylene was mixed with 5 parts of the above-mentioned mixture using a heat exchanger, and a toothbrush handle was molded using an injection molding machine.
しかし成形品のマイクロカプセルの分散が悪く斑点状を
多数表面に生じ、また成形温度が高いためパラ査の分解
逸散のロスが多く香の大巾な減少を生じた。However, the dispersion of the microcapsules in the molded product was poor and many spots appeared on the surface, and because the molding temperature was high, there was a lot of loss due to decomposition and escape of the parallax, resulting in a significant decrease in fragrance.

It was possible to mold the toothbrush handle at an injection molding temperature of 150°C, which is 50°C lower than 200°C. It has good dispersibility and is homogeneous, and because it is molded at a low height of 1 m, there is very little loss of rose scent, and the scent retention period of the shoe is one year.

However, this molded product has many bumps on the surface of the molded product due to poor dispersion of microcapsules, and the molded product is cloudy and there is no product measurement. The incense retention period was also short, 8 weeks, due to the high molding temperature and a large loss of incense.

果をもったものが得られる。90 parts of polyethylene was added to 10 parts of this material, mixed well, and a film having a thickness of 25 μm was formed using a tubular film forming machine. A homogeneous film with good transparency and no fish eyes or 70-marks was obtained. The fragrance retention period was 8 months or more at room temperature.As shown in the examples above, by using the high concentration mask pellets according to the present invention, molded products such as molded products, sheets, and films can be made homogeneously without the addition of various additives. It is possible to obtain a product with a sustained release effect over a long period of time.
