Problems solved by technology

[0006] In the above technical solution, epoxy resin is used as the main resin of the anti-slip glue, and the rare earth silicate-based long-lasting afterglow material and the rare-earth aluminate-based long-lasting afterglow material are dispersed in it. After the epoxy resin is cured, the rare-earth aluminate-based long-lasting Material coating, forming a protective layer, overcomes the problem of poor water resistance of rare earth aluminate-based long-lasting materials, thus giving it better stability

Abstract

The invention provides an epoxy-based long-lasting fluorescent anti-slip adhesive and a preparation method thereof. The fluorescent anti-slip adhesive includes components A and B, and the component A includes epoxy resin, long-lasting materials and fillers. The B component includes an epoxy resin curing agent, wherein the long afterglow material is obtained by mixing a rare earth silicate based long afterglow material and a rare earth aluminate based long afterglow material in a weight ratio of 1:3 to 3:1. The fluorescent anti-slip adhesive of the invention overcomes the problem of poor water resistance of rare earth aluminate-based long-lasting materials, has good stability, has good fluorescent effect, and has high afterglow brightness and long duration.

Description

technical field [0001] The invention relates to the field of anti-slip adhesives, in particular to an epoxy-based long-lasting fluorescent anti-slip adhesive and a preparation method thereof. Background technique [0002] For the sake of safety, anti-slip products and fluorescent indicators are usually installed in corridors, stairwells or places with low light, especially at night, in the event of power failure or building fire, the two work together to protect people's lives. The anti-slip products on the market today are mainly anti-slip strips, anti-slip tapes and anti-slip rubber, and the cost of various fluorescent indicators on the market is relatively high, and the installation method is cumbersome. The two must be used at the same time to play the role of maximum security, but currently there is no product on the market that combines the functions of fluorescent indicators and anti-skid. [0003] In addition, the most widely used fluorescent materials at present ar...
