[0057] Experimental Example 1 Testing Heat Resistance Properties-Wallpaper

[0058] Each liquid composition prepared in Example 1 and Comparative Example 1 was brushed on a wallpaper with a width of 20 cm and a length of 29 cm, and the brushed wallpaper was placed in a thermostat (pyrostat) for 3 hours, and then the heat resistance property was tested. The results are shown in Table 1.

Abstract

The present invention relates to a composition for fire-resisting and fire-extinguishing with pro-environmental characteristic. More particularly, the present invention relates to the composition comprising monobasic sodium phosphate, dibasic ammonium phosphate, borax, boric acid, olyoxyalkylated alkyl phosphoric acid ester and water.

Description

technical field [0001] The present invention relates to environmentally friendly flame retardant and fire extinguishing compositions. In particular, the present invention relates to compositions comprising monobasic sodium phosphate, diammonium phosphate, borax, boric acid, polyoxyalkylated alkyl phosphates, and water. Background technique [0002] Comparing electricity and fire consumption in everyday life, living spaces, large downtown areas, factories and licensed shops are densely distributed and built into closed units, leading to increased fire hazards. Therefore, most fires all cause fires such as subway fire accidents and forest fires. To prevent fires from occurring, it is important to suppress early misfires. [0003] However, fire extinguishing compositions used in recent years have poor flame retardancy and weaken when heated. As another reaction occurs, the flame retardant effect is exhausted and it is easy to re-ignite. Furthermore, said compositions contai...
