Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a simple manufacturing method for obtaining fragrance sheets containing various patterns and colors.

Conventionally, aromatic agents have been made by molding a sublimable aromatic agent itself into a specific shape, or by impregnating a single synthetic resin material pre-molded into a specific shape with a fragrance.

The appearance forms that can be produced by these conventional fragrances have been limited due to factors originating from their respective structural characteristics. That is, regarding color tone, in the former case, it is limited to a single color based on the basic color scheme of the aromatic agent itself, and in the latter case, it is limited to a single color based on the basic color scheme of the synthetic resin material itself. This is because both of the above are limited to those based mainly only on the external shape.

Therefore, the above-mentioned conventional methods for producing fragrances include a method in which raw materials colored in a specific color are molded into a specific shape, or a simple method such as immersing a pre-shaped synthetic resin material in a fragrance liquid for a certain period of time. It was just a method being used.

The object of the present invention is to provide a simple manufacturing method for obtaining an aromatic sheet that maintains appropriate sustained release of aroma and has various patterns and colors on the surface of the conventional aromatic agent described above. It is characterized by the following configuration.

That is, the first step involves forming a thin thermoplastic resin pattern material printed with an appropriate pattern, and separately preparing an aromatic material by adding an appropriate ingredient to a transparent thermoplastic resin material.
a second step of uniformly applying the aromatic material along the surface of the patterned material so as to form a sheet as a whole to form an adherend; This consists of a third step of heating for a certain period of time, and a fourth step of cooling and curing the knee.

In the method for producing a patterned fragrance sheet according to the present invention characterized by the above-mentioned steps, in the first step, the base material type of the pattern material is changed according to the base material type of the aromatic material in the subsequent step. It is determined. That is, it is necessary that the above-mentioned base material types exhibit mutual affinity during heating, and that there is no significant difference in their respective melting temperatures and also that their coefficients of thermal expansion are not significantly different. For example, when using hard polyvinyl chloride resin as a base material for an aromatic material, for example, a vinyl resin may be formed into a film on polyester resin or polychloride. I can do it. The base material for other pattern materials can be nylon, polystyrene, polycarbonate, etc.

Further, the pattern on the pattern material can be formed by a general method such as gravure printing.

Regarding the pattern material, hard polyvinyl chloride resin paulownia is formed by punching or molding to form a thin substrate exhibiting rigidity, and a thin polyester reflex, (Rem), etc. with an appropriate pattern printed on the surface of the thin substrate is co-condensed. The structure may be bonded with a commonly used adhesive such as an amorphous polyester adhesive. When a patterned material having this structure is used, the film-like part on which the pattern is formed is stably fixed based on the rigidity of the thin substrate, so that the second step and the third step This makes it possible to carry out the operations, that is, the deposition and heat treatment of the aromatic material, under more stable conditions and with simpler operations.

Further, the thin substrate functions as a support substrate for the fragrance portion made of the fragrance material in the fragrance sheet after production.

Next, the transparent thermoplastic resin material used as the base material for the aromatic material in the latter stage of the first step is one that contains a fragrance in a manner that allows it to be fragrant to the outside world at room temperature after the curing treatment in the fourth step. is required.

In addition, the processing form of the aromatic material in this process step should be a pellet-like material that can be applied with injection molding, or a paste-like material that can be filled at room temperature or in a heated state. I can do it. In addition, the paste aromatic material is
For example, when a polyvinyl chloride resin is used as a base material, it can be obtained by first processing the resin material into a fine powder, and then dispersing it with a plasticizer and a diluent.

In addition, the flavoring species added at the latter stage of the first step are as follows:
The condition is that it does not volatilize and decompose at the heating temperature set in the 6th step. For example, if the base material of the aromatic material is polyvinyl chloride resin, linaloe oil containing linalool as the main component, Camphor oil, eucalyptus oil containing geraniol as a main ingredient, Haraura oil, mint oil containing l-menthol as a main ingredient, etc. can be used.

Next, in a second step, an aromatic material is applied to the patterned material. In this deposition process, when the aromatic material is formed into pellets, the aromatic material is injected in a molten state by an injection molding machine into the patterned material fixed in the mold. When the paste is formed, it can be processed by filling it into a mold, and a sheet-like adherend can be obtained.

The former process has the advantage that the types of fragrances that can be used are limited depending on the melting temperature conditions, or can be processed in a short time using existing injection molding machines. In the above treatment, since the deposition treatment conditions are more gentle, there is an advantage that a relatively wide range of fragrance types can be used.

Next, in the third step, the adherend obtained in the second step is heated at the melting temperature of the base material of the aromatic material for a certain period of time, so that the interface between the constituent parts of the adherend is heated. Polymerization occurs resulting in a unitary configuration.

In this case, the conditions are required so that the fragrance contained in the aromatic material does not decompose by volatilization. For example, if the fragrance contained is mainly linalool (boiling point: 197-199°C), When the base material is polyvinyl chloride resin, the heating conditions in this step are 160 to 18
Heating is applied for about 20 minutes at 0°C, and if nylon is the base material of the aromatic material, the heating condition in this step is 150 to 180°C for about 20 minutes when the solid phase polymerization method is applied.
Heat for 1 minute or more.

The adherend that has undergone the treatment in the third step is then cooled and hardened to obtain a fragrance sheet as a product.

As described above, the present invention provides a method for producing sustained-release fragrance sheets with various patterns and colors using existing production equipment, a simple equipment configuration, and simple processing operations. It is something to do.

Next, the 1ffiJ patterned shrine is fixed in a mold for a sheet, and the above-mentioned paste-like aromatic material is filled into this to form an adherend.

Detailed Description of the Invention The present invention relates to a simple manufacturing method for obtaining fragrance sheets containing various patterns and colors. Conventionally, aromatic agents include those made by molding a sublimable aromatic agent itself into a specific shape, or those made by impregnating a single synthetic resin material pre-molded into a specific shape with a fragrance. The appearance forms that can be produced by these conventional fragrances have been limited due to factors originating from their respective structural characteristics. That is, in the former case, the color tone is limited to the basic color scheme of the aromatic agent itself, and in the latter case, it is limited to single-colored threads based on the basic color scheme of the synthetic resin material itself, and in the case of the pattern, This is because both of the above are limited to those based mainly only on the external shape. Therefore, the conventional manufacturing methods for the above-mentioned fragrances include molding a raw material colored in a specific color and molding it into a specific shape, or immersing a pre-shaped synthetic resin material in a perfume liquid for a certain period of time. Only simple methods such as these were used. The purpose of the present invention is to provide a simple manufacturing method for obtaining a fragrance sheet that maintains an appropriate sustained release of fragrance and has various patterns and colors on its surface, compared to the above-mentioned conventional fragrances. It is characterized by the following configuration. That is, a pattern material made of thermoplastic resin with an appropriate pattern and color is formed into a thin thickness, and an aromatic material is separately prepared by making a transparent or translucent thermoplastic resin contain an appropriate fragrance. a second step of heating the aromatic material at a melting temperature for a certain period of time; and a second step of applying the aromatic material in a layered manner along the surface of the patterned material so as to form a sheet as a whole. The third step is followed by the W4 step of cooling and curing. In the method for producing a patterned aromatic sheet according to the present invention characterized by the above-mentioned steps, in the first stage of the first step, the base material type of the pattern material is selected according to the base material type of the aromatic material. This is necessary for the structure of the patterned fragrance sheet as a product, and it is desirable to use materials with similar physical properties such as coefficient of thermal expansion.For example, use hard polyvinyl chloride resin as the base material for the fragrance material. In some cases, polyester resin or polyvinyl chloride resin can be formed into a film and used as the base material for patterned paulownia wood. Other materials that can be used as pattern materials include polyamide resin, polystyrene, polycarbonate, and the like. Furthermore, the patterns and colors on the patterned material can be applied by various printing methods such as transfer, hot stamping, silk printing, gravure printing, and offset printing. In addition, as a pattern material, a thermoplastic resin material such as a hard polyvinyl chloride resin material is formed into a rigid thin substrate by punching or molding, and an appropriate pattern and color are applied on the surface of the thin substrate by a printing method. It is possible to have a structure in which a polyester film or the like is adhered with an adhesive such as a co-condensed amorphous polyester adhesive. When a patterned material having this structural feature is used, the third and fourth steps can be performed under more stable conditions based on the rigidity of the thin substrate. Further, the thin substrate functions as a supporting substrate in the manufactured fragrance sheet. Next, the base material type of the aromatic material in the latter stage of the first step is as follows:
After the processing in each of the first to fourth steps, the material is transparent or translucent so that the fragrance can be fragrant to the outside at room temperature, and the pattern and color of the pattern material can be seen through. Examples include A, S resin, AC8 resin, E, VA resin, AB S resin, ethylene vinyl alcohol copolymer resin, vinyl chloride resin, and vinyl chloride resin. Elastomer resin, MBS resin, chlorinated polyethylene, polyether resin, polyamide resin, polyamide elastomer, polyarylate resin, polyacetal resin, polyester resin, high pressure polyethylene, medium and low pressure polyethylene, butadiene resin, polycarbonate resin, polystyrene resin, fluororesin, Examples include polypropylene, methacrylic resin, and methylpentene polymer. The aromatic material in this step can be prepared in the form of pellets or paste to which injection molding can be applied. In addition, when preparing a paste aromatic agent, for example, when using polyvinyl chloride resin as a base material, firstly, the resin material is processed into a fine powder, then it is dispersed with a plasticizer and a diluent, and then further processed as appropriate. It can be obtained by adding a flavoring agent. In addition, the fragrance column to be included in this process step must be one that does not volatilize and decompose at the heating temperature set in the sixth step. For example, the fragrance material base material or polyvinyl chloride resin In this case, linaloeura oil and camphor oil containing linalool as a main ingredient, eucalyptus oil and rose oil containing geraniol as a main ingredient, mint oil containing 1-menthol as a main ingredient, etc. can be used. Next, in the second step, the aromatic material prepared in the previous step is heated at the melting temperature of the base material for a certain period of time. Thus, the aromatic material is obtained in a plasticized state. This condition occurs in the injection molding machine when the injection molding method is applied to the fragrance material in the form of pellets. Note that if the aromatic content is in the form of a paste, a polymerization reaction of the resin base material itself occurs at this process step. In addition, in this process step, it is required that the conditions are such that the fragrance contained in the aromatic material does not decompose by volatilization.
), and when the base material of the aromatic material is polyvinyl chloride resin, the appropriate heating conditions for this step are heating at 160 to 180°C for about 20 minutes; When a polyamide resin is used as a base material for an aromatic material and a solid phase polymerization method is applied, heating at 150 to 180°C for about 20 minutes is suitable as the heating condition in this step. Next, in the third step, the aromatic material in the plasticized state in the previous step is applied along the patterned material surface (including the concave portions) to I in a tatami form or a covering form. At this time, Since the bipartite fragrance material is heated to the melting temperature as described above, the product is obtained in an extremely tightly bonded state at the interface with the pattern material, and thus 1. The pattern and color of the fragrance sheet as a product become extremely clear through the transparent or translucent fragrance material part. A fragrance sheet as a product is obtained through the process.As described above, the present invention can produce sustained-release fragrance sheets with various patterns and colors with a simple equipment configuration using existing manufacturing equipment. This provides a method that can be manufactured with simple processing operations.Example 1 A patterned material is formed by gravure printing an appropriate pattern and color on a polyester film, and is then cut to an appropriate size.Separately, Polyvinyl chloride resin material (components: polyvinyl chloride...100 parts by weight, plasticizer...60 parts by weight, stabilizer...2 parts by weight) is made into a fine powder, and to this is added Linaloeura, eucalyptus oil, A paste-like aromatic material is prepared by mixing and stirring a mixed fragrance such as Mintura and a diluent.Next, the aromatic material is heated in a heating furnace at 180°C for about 20 minutes, and this heat treatment is performed.
