Embodiment Construction
[0026] The fireproof layer component of the present invention and the composite glass manufacturing process are described in detail below:
[0027] Anti-ultraviolet composite fireproof glass, including two glass substrates, filled with a fireproof layer, the glass substrate can be tempered glass, and the fireproof layer includes the following components by weight percentage:
[0028] Methyl methyl ester 50%; Dibutyl ester 15%; Sodium sulfite 20%;
[0029] Zinc oxide (ZNO) 1.3%; Magnesium hydroxide 3%; Butyl phthalate 0.2%;
[0030] Acrylamide 10%; Ethanol 0.1%; 2-Hydroxy-4-methoxybenzophenone 0.4%.
[0031] Function description of each component:
[0032] 1. 2-Hydroxy-4-methoxybenzophenone
[0033] The benzophenone containing two adjacent hydroxyl groups has the strongest ability to absorb ultraviolet rays, and has a strong absorption effect on ultraviolet light with a wavelength of 330-370nm.
[0034] 2. Butyl phthalate
[0035] Enhance heat resistance, light resistance ...
