Problems solved by technology

However, these enamel signs all use iron or stainless steel as the substrate, which is easy to rust and has a short service life; the glaze firing temperature is high, and the reaction between the luminescent powder and the glaze is serious, which reduces the luminous brightness of the glaze, shortens the afterglow time, and improves the smoothness and gloss of the glaze surface. Not good, there are defects such as bubbles, rolling glaze, sinking glaze, etc.

Abstract

The invention relates a prodn, method of long persistence enamel that aluminium material is used as baseboard. Aluminium alloy board, aluminium board or aluminium foil are used as baseboard which one or mutiple layer of glaze is fired on, frit is composed by long persistence luminous powder and frit powder with low melting point. Long persistence luminous powder is luminous powder is luminous powder activated by various ions, the low melting point frit powder is glass powder with low melting point, weight percentages are 10-35 and 90-65. The invention has characteristic that said enamel can continously light for long time after absorbing visible light, until evening it can seen by naked eye in dark place.

Description

technical field [0001] The invention relates to a preparation method of long afterglow enamel with aluminum material as the matrix. technical background [0002] There are many kinds of enamel signs, such as billboards, billboards, road signs, house numbers, warning signs, etc., which are widely used. However, the general enamel signage generally has the same problem, that is, in a dark environment, the content of the signage cannot be seen clearly even at close range. In order to overcome this problem, CN1198413A and CN1202472A etc. provide the long afterglow enamel signboard made of aluminate long afterglow material excited by europium ions added to the base glaze. Due to the low luminance and short afterglow time of the long afterglow luminescent powder itself, the performance of the signage is not satisfactory. With the emergence of aluminate long afterglow luminescent materials co-activated by rare earth ions and europium with excellent performance, CN2342430Y, CN2434...
