Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fragrance synthetic paper with excellent fragrance retention properties.

Various types of papers that emit scents have been developed and put into practical use, but conventional products do not involve simply applying fragrances or substances containing fragrances to the surface of paper, etc., or impregnating paper, etc. As a result, the air permeability of paper etc. promotes the release of fragrance.As a result, although the fragrance is good, it has the disadvantage that the fragrance diffuses in a short period of time, resulting in poor fragrance retention. Ta.

Therefore, if the amount of fragrance or substance containing fragrance applied to or impregnated into the paper, etc. is increased, the time for which the fragrance remains on the paper, etc. will be increased, and the fragrance retention property will be improved. Although it can be made to be of good quality, it is impossible to put it into practical use because the fragrance emitted in the initial stage is too strong due to the good numbering properties of the product made in this way.

In view of the above-mentioned nine drawbacks of the prior art, the present invention has been made with the sole purpose of providing a fragrance-emitting synthetic paper that can emit a fragrance of constant strength over a long period of time. A synthetic paper with a porous structure surface layer made of synthetic resin such as styrene, calcium carbonate, titanium oxide, etc. is provided on at least one side of a resin film, and by mixing all the fragrance ingredients in the surface layer of the synthetic paper, a constant fragrance can be maintained over a long period of time. It is characterized by being designed to emit the following.

Although the figure describes an embodiment in which the surface layer 2 is provided only on one side of the plastic sheet 10, it is also possible to form the surface layer 2 f'L on both sides of the plastic sheet 1.

The fragrant synthetic paper of the present invention constructed as described above can be produced, for example, by the following method.

That is, a synthetic resin such as polystyrene or chlorinated polypropylene is dissolved in an appropriate organic solvent, and the above-mentioned inorganic filler, an optional plasticizer, etc., and an appropriate fragrance component are added thereto to prepare a coating solution. A wet method is used in which the coating solution is coated on the plastic sheet 1 and then passed through water to diffuse the organic solvent and coagulate the synthetic resin, followed by further drying, or a similar coating method is used. It can be manufactured in exactly the same process as conventional synthetic paper by applying a solution onto the plastic sheet 1 and then drying it without passing it through water. .

Thus, the fragrance-producing synthetic paper of the present invention produced as described above has excellent fragrance retention properties. The reason for this is that the fragrance ingredients are mixed in the surface layer 2, which has a porous structure, and are further combined with inorganic fillers such as calcium carbide, so that the volatilization rate of the fragrance ingredients is low and for a long period of time. Both r(
Unlike regular paper, etc., the plastic sheet 1 blocks ventilation, so it is possible to emit a scent with a constant strength over a long period of time.Especially when molecular capsules are used as fragrances, the fragrance ingredients are first released from the capsules. It exits into the surface layer of the polylithic structure, and then exits from the surface layer into the atmosphere.
It is thought that it has even better fragrance retention.

In addition, due to the above-mentioned properties, even when a relatively strong fragrance component is mixed with the scented synthetic paper of the present invention, the fragrance component evaporates little by little over a long period of time. It does not mean that it cannot withstand use.

Furthermore, the fragrant synthetic paper of the present invention can be obtained using the conventional synthetic paper manufacturing process, so it can be produced at low cost, without losing the properties of the synthetic paper itself, and with improved printability, moldability, etc. It has a wide range of uses, such as printing on it as appropriate to hang it on a wall, or molding it and using it as a small plate, etc., making it extremely practical.

Next, an example of the present invention will be shown.

Example 1 Polystyrene 600g f dimethylformamide 3p0
To this solution, add 100 g of dioctyl phthalate as a plasticizer, further add 1500 g of carbonate as an inorganic filler, and 30 to 60 g of coumarin as a fragrance, and stir to form a coating solution. Prepare.

This coating solution was continuously coated on a biaxially oriented polystyrene film with a total thickness of 701 L using a roll coater, and then passed through water and coated with dimethylformamide. While diffusing, the polystyrene was coagulated and further dried to obtain an example of the fragrant synthetic paper of the present invention.

This thing continued to emit a scent of constant strength for a long period of time.

Example 2 Chlorinated polypropylene (number average molecular fig = ao, o
oo.

600g of chlorine content = approx. 28% by weight) to 3000g of toluene
A coating solution is prepared by adding to this solution 4 so, g of titanium oxide (average particle size = o, 1 p) as an inorganic filler, 900 g of calcium carbonate, and 30 g of coumarin as a fragrance, and stirring.

This coating solution was continuously coated onto a polypropylene film using a gravure roll and dried at 120°C to obtain an example of the synthetic paper of the present invention.

This thing continued to emit a scent of constant strength for a long period of time.

Example 3 Styrene-acrylonitrile copolymer 600g' (i7
Dissolve the solution in 2000 g of dimethylformamide, add 10 g of trioctylphosphini and 130 g of ethyl acetoacetate as a fragrance, and further suspend and stir 600 g of kaolin to prepare a coating solution. This was applied continuously to a styrene-butadiene compound film with a thickness of 120 mm using a roll coater, gelatinized in water, and further soaked in hot water adjusted to 95 to 100°C for 10 min. After passing for a second, dry with hot air at 80°C or less. The same treatment was carried out on the back side to obtain an example of a numbered synthetic paper having a thickness of 16,011 mm, white, opaque, and semi-gloss.

This thing continued to emit a scent of constant strength for a long period of time.

Example 4 Polyvinyl chloride 600g q dimethylformamide 48
360 g of dioctyl phthalate and 1800 g of calcium carbonate powder are added to the solution and stirred to prepare a coating solution. Apply it evenly to both sides of the axially stretched polyvinyl chloride film, and
The coating layer was immersed in water at 0°C for 60 seconds to gel (7)
Next is this film? It was immersed in hot water at 60°C for 30 seconds, further immersed in an aqueous solution of 08C magnesium cyclide for 10 seconds, and then dried at 60°C to a thickness of 1201. An example of scented synthetic paper 'If' was obtained.

This product emitted a scent of a certain intensity over a long period of time.

Example 5 200 g of polyvinyl chloride 117 dissolved in 2000 g of dimethylformamide, 30 g of dioctyl azelate, 200 g of calcium carbonate, 200
A coating composition tmW was prepared by adding g of kaolin, 10 g of titanium oxide, and 20 g of a compound f in which heliotropin was included in cyclotextrin at a weight ratio of 1:1 as a fragrance. This composition was applied to a polycarbonate film with a thickness of 501 L using a roll coater, and then kneaded in water.
It was allowed to gel for 50 seconds, then passed under a nozzle spouting steam at 100°C for 3 seconds, and finally dried at 60°C for 30 seconds.

This substance emits a constant, strong fragrance over a long period of time and is red;
