管球用マーキング剤が要望されている。 Conventionally, heat-resistant red pigments such as cadmium selenide and cadmium sulfide have been used as red marking agents for forming marks on substrates such as glass tubes. However, in recent years, these markings have become extremely difficult to use due to pollution concerns, and as an alternative, red markings for tubes have been developed that are thermally stable and have strong adhesion to glass tubes. agent is requested.

用マーキング剤を提供するものである。 The present invention is intended to meet these demands, and has good properties such as not causing any pollution problems, being thermally stable, having a high adhesion strength to the substrate, and having no uneven marking. The present invention provides a red-colored marking agent for tubes.

たマークをこするとマークが薄くなつてしまうこ
とが判明した。 As a result of various studies, the present inventors have found that there is no problem with pollution as a red marking agent for tubes.
They also discovered that iron oxide powder is superior in terms of red color development. however,
A low-melting glass powder as a binder and glycerin and ethyl alcohol as a binder are added to the iron oxide powder, and after grinding and mixing in a ball mill, the marking agent is concentrated and made into a paste, which is then used to coat the outer surface of the glass tube of a fluorescent lamp. Stamp it, then heat it to about 500℃ with a gas burner to melt the low melting point glass,
When a marking agent is applied to the outside surface of a glass tube, the color tone of the mark obtained becomes blackish due to the heat generated during baking of the marking agent, and the adhesion strength of the marking agent to the surface of the glass tube is also weak. It turns out that if you rub the mark, it will fade.

ねくことも判明した。 In addition, stamping is usually done by using a roller to spread the marking agent thinly on the table, attaching a rubber stamp for stamping to this, and then pressing the rubber stamp on the outer surface of the glass tube to make the marking agent adhere. However, during the marking process, the spreading of the marking agent on the table becomes extremely slow, making it difficult for the marking agent to adhere to the rubber stamp, resulting in uneven marking, and may even lead to a situation where the stamp cannot be stamped. found.

ることを見い出した。 Therefore, as a result of further investigation, the present inventors added silver oxide powder to iron oxide powder, and added 10 to 10% silver oxide powder to 100 (weight ratio) of iron oxide powder.
It has been found that by adding 30% (weight ratio), the various problems described above that occur when iron oxide powder is used alone can be solved.

During the marking process, problems such as poor elongation on the table and difficulty in stamping occur.

れない。 On the other hand, according to the marking agent for tubes of the present invention, by adding a predetermined amount of silver oxide powder to iron oxide powder, the silver oxide powder can be mixed uniformly with glycerin and easily blended in, thereby promoting drying. Since this effect is suppressed, the elongation of the iron oxide powder on the stand is improved, making it easier to stamp. In addition, the color of the mark does not change after heating and baking the marking agent, and it is thermally stable.Furthermore, because the particles of silver oxide powder are smaller than the particles of iron oxide powder, it is easy to bond with the surface of the glass tube. Since the adhesion of the marking agent is improved, the adhesion strength of the marking agent is also increased. When the weight ratio of iron oxide powder is 100 and the weight ratio of silver oxide is less than 10, the above effect cannot be obtained, and when the weight ratio exceeds 30, the color tone of silver oxide becomes strong and yellowish, resulting in the desired color tone. is not obtained.

Weighed each of the above ingredients, obtained a marking agent in the same manner as in the above example, and also obtained the baking temperature etc. from the above example. I got the mark under the same conditions. Initially, the marking agent had good spreadability, but as time passed, the spreadability deteriorated, making it difficult to print and causing uneven printing. Furthermore, after the marking agent was heated and baked, the color of the mark changed to a blackish color, and the adhesion strength to the surface of the glass tube was also weak.
