JPH0199561A - Molded aromatic agent - Google Patents

Abstract

PURPOSE:To integrally mold various aromatic plastic molded products, by molding plastic which is a molding material being processed at 200 deg.C or lower with a specified amount of aromatic agent mixed into the plastic. CONSTITUTION:An aromatic agent is, e.g., of low-pressure polyethylene, has a melt index of 20, specific gravity of 0.91-0.93, apparent specific gravity of 30-35 1bs/cubic feet, normal cylindrical pellet size of 0.125X0.815, no color tone, and uniform dispersion of perfume. Plastic, a molding material, consists of general polyolefin such as low-pressure polyethylene, high-pressure polyethylene, polypropylene and EVA. An aromatic agent of 0.1-50% is mixed into a plastic molding material being processed at 200 deg.C or lower to be kneaded to obtain a plastic molded product with aroma.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a molded fragrance containing a fragrance during the molding process of a plastic product.

(Prior art) In recent years, air fresheners have been used for a variety of purposes such as household goods and car goods. Most of them are stored in containers.

(Problem to be Solved by the Invention) Air fresheners stored in such containers require special efforts in the structure of the container in order to volatilize the fragrance, and this is especially true for automobiles that use liquefied air fresheners. In fi3,
There was a need for a container 4 with a structure that would prevent the fragrance from leaking outside. In addition, some aroma devices are made by impregnating a decorative item such as a doll with a liquefied aromatic agent or containing microcapsules, which try to evaporate the scent from the doll's body. However, in the case of such decorative items, it has been difficult to constantly evaporate the fragrance and maintain the fragrance for a long period of time. The former loses its scent once the solution evaporates, while the latter requires some kind of external force to destroy the microcapsules in order to volatilize the scent, so it is not applicable to objects that are simply displayed as static objects. It was something.

(Means for Solving the Problems) Therefore, the present invention has been made to solve the above-mentioned problems. There is a molded aromatic agent formed by mixing 0.1% to 50% of an aromatic agent and molding the mixture.

(Function) The molded aromatic agent of the present invention is mixed and kneaded during the molding process of plastics, so it can be molded into a variety of products depending on the purpose, without impairing the purity of the plastic. Perfumed ancient molecules can be diffused into the air. Additionally, by labeling, printing, or painting a portion of the plastic surface, it is possible to control the diffusion of scent into the air.

(Example) The material of the air freshener is low pressure polyethylene with a melt index of 20. Specific gravity is 0.91-0.93. Apparent specific gravity is 30 to 35 bonds per cubic foot (4 per cubic meter)
80.5-560.6 kg), cylindrical (3.2 m
m x 4.7 mm) Two tones are colorless and the degree of dispersion of fragrance is uniform. On the other hand, plastics that are raw materials for molding are made of common polyolefins such as low-pressure polyethylene, high-pressure polyethylene, polypropylene, and EVA.

Then, to the above-mentioned plastic raw material for molding processing, which is being processed at a high temperature of 200°C or less.

-Contains 0.1% to 50% of F aromatic agent! mixture.

A plastic molded product is kneaded and scented.

For example, when this plastic molded product is molded into automobile-related parts, it can be used for steering wheel horn parts (horn covers), ventilation louvers, sun visors, dash board covers, etc., and it can also add fragrance to molded parts. Can be done. It can also be used as household health and hygiene products and miscellaneous goods such as lampshades, telephones, and toilet seats.

(Effects) As explained above, according to the present invention, by mixing 0.1% to 50% of an aromatic agent into plastic, which is a raw material for molding, which is being processed at a high temperature of 200°C or less, and molding it. Since a variety of scented plastic molded products can be integrally molded depending on the purpose, there is no need for a storage container like conventional fragrances. Therefore, the liquefied aromatic agent can be used with peace of mind without having to consider leakage or devising measures to achieve the volatilization effect. Furthermore, even a still life like a single doll can be used to enjoy the scent without requiring any external force. Moreover, there are labels, decorations, and stickers that cover some of the scented plastic molded products.

By printing, painting, etc., the portion of one surface that is exposed to the air is reduced, thereby reducing the diffusion of scent molecules into the air, which also has the effect of extending the life of the product.
