Purpose) Paints that have been commonly used as base materials for luminescent products have poor flexibility, heat resistance, tensile strength, and elongation, and therefore are difficult to solve on flat substrates. There is a problem in that if the substrate is bent after being applied and cured, the luminescent coating may crack or peel off, and plastic has relatively low flexibility, so the shape of the product may be affected. There was a problem in that the mold had to be raised each time.

としては不向きである。As mentioned above, clay-like synthetic rubber is listed as a base agent in Japanese Patent Publication No. 54-28772, but what is disclosed in this publication is limited to handcrafted materials and is not suitable as a general-purpose material. It is.

形物の製法を提供とすることにある。Therefore, the main object of the present invention is to provide a method for producing a luminescent rubber molded product that eliminates the defects of conventional luminescent products and can be used as a luminescent general-purpose material by using rubber as the base material. There is a particular thing.

A luminous pigment and a vulcanizing agent are added, kneaded, and molded.
The problem is solved by a method for manufacturing a luminescent rubber molded product, which is characterized by heat vulcanization, and the above object is achieved.

製品の種類にも依存するが汎用シリコーンゴム対高強度
シリコーンゴムを７対３Ｐ？度にするのが好ましい。Raw material rubbers used in the method of the present invention include silicone rubber, butadiene rubber (BR), and ethylene propylene terpolymer (EPT). This is because these rubbers have excellent transparency and therefore have good luminescence and luminescence due to the luminescent pigments.When using silicone rubber as a raw material rubber, it is necessary to use only general-purpose silicone rubber containing vinyl groups. If used, the tear strength and heat resistance will decrease, so it is preferable to use a silicone rubber compound blended with a high-strength silicone rubber containing phenyl groups. The blending ratio of both depends on the type of product desired, but is general-purpose silicone rubber to high-strength silicone rubber 7 to 3P? It is preferable to do so at a certain degree.

ましい。蓋し、１５％以下では発光」が低過ぎ、又３５

不利となるからである。Various types of luminous pigments have been considered, but ``
Particularly preferred are those commercially available as "Lamilax". The compound layer preferably accounts for about 15 to 35% of the rubber compound. If the lid is closed, the luminescence is too low and 35% or less.
This is because even if more than % is added, the amount of light emitted will not be as high as that shown above, which will be disadvantageous in terms of cost.
尚、加硫剤として加硫物系のものを用いるとゴム成形物
に濁りを生じ発光効果が低下するので、酸化物系のもの

しい。Incidentally, if a vulcanizate-based vulcanizing agent is used as the vulcanizing agent, the rubber molded product becomes cloudy and the luminous effect is reduced, so an oxide-based vulcanizing agent, such as the one commercially available as TB-20, is preferable.

The results of the measurement and investigation of the relationship between the irradiation time for luminescence and the amount of luminescence are shown in Table 1 below, and it was found that the irradiation time for this sample was about 2 minutes.

and B, sample area: 277.8 cm2), and the luminous sheet according to Example 1 was cut to prepare sample C (sample area is the same as above). Each of these samples should be irradiated for 2 minutes with a 430 lux light source.
Il111>, then the samples were shut off from the light source, and the luminescence illuminance exhibited by each sample was measured over time in the same manner as in Example 1. The results were as shown in Section 2 below. From this result, the initial illuminance improves when the blending ratio of the luminescent content is increased, but there is almost no difference in the latter illuminance, and the initial illuminance depends on the use of the molded product, but is 0. Since flux level or higher is desirable, the lower limit of the amount of phosphorescent pigment added is approximately 153mM.
%, and since Lamilux, which is a luminescent pigment, is relatively expensive, it is understood that it is not preferable in terms of cost to increase its blending amount to 35% or more.

It has good elasticity and good elongation. The rubber used as the base material for this phosphorescent rubber molding has excellent aging resistance, and the phosphorescent pigment is dispersed within this vulcanized rubber molding, so the molded product obtained by the method of the present invention has excellent aging resistance. If it is stored for several years, for example 3 to 4 years, it will become luminescent if exposed to light. In addition, if it is formed into a sheet, it can be wrapped or cut into a predetermined shape and pasted to serve various purposes.
