Abstract
Disclosed is a method for manufacturing a fire-resistant resin composition, a fire-resistant member manufactured from the composition, and a method for manufacturing the fire-resistant member, wherein fire-resistant members are installed in a wire penetration hole of a wall structure and, in the event of a fire, foam and expand by the heat of the fire to prevent the spread of the fire across the wall structure.
Claims16
A method for manufacturing a fire-resistant resin composition, the method comprising:
- a dissolution step of feeding 100 parts by weight of water, 10-30 parts by weight of pentaerythritol (PE), 5-30 parts by weight of a melamine resin powder, and 30-60 parts by weight of ammonium polyphosphate (APP) into a tank, followed by heating at a temperature of 100° C. for 2-3 hours;
- a reaction step of further mixing 10-50 parts by weight of a liquid-phase urea resin, obtained by mixing 40-80 wt % of water and 20-60 wt % of a urea resin, and 0.2-1.0 parts by weight of ammonium chloride, relative to 30-60 parts by weight of ammonium polyphosphate, followed by stirring while boiling, thereby forming an APP-pentaerythritol polymer;
- an aging step of stopping stirring, followed by aging and curing at room temperature for 2-4 hours;
- a pulverization step of pulverizing the APP-pentaerythritol polymer in a lump form to a particle size of 100 to 300 mesh;
- and
- a mixing step of mixing 30-200 parts by weight of the APP-pentaerythritol polymer powder and 0.1-3.0 parts by weight of a platinum catalyst, relative to 100 parts by weight of a silicone resin.
