The role of modified amino resin fire retardant coating FSF-1 with modified amino resin composite Jike as one. In the development process, we find that the choice of flame retardant dispersions with polyvinyl acetate and / or acrylic acid copolymer emulsion mixture,[link widoczny dla zalogowanych], the stability of the whole, or even Lu uniform. Modified nitrogen-based flame retardant resin dispersions pre-mixed with Taiwan some time, then add polymer emulsion stability is good. Tree feeding the polar amino group dispersion can fire it with the full run small-minded and flame retardant dispersions of application of the investment group effective association, wrapped its surface, to stabilize the dispersion effect of addition, the amino resin itself some foam depression. Nitrogen-based resin modified high carbon content, the coating thermal expansion of dense foam carbonized layer formed to improve the simple use of polyvinyl acetate and acrylic acid copolymer emulsion charring layer of flame resistance. 2. Base material of the coating with composite base material, sub-put long-term stability at room temperature without emulsion breaking,[link widoczny dla zalogowanych], and the coating performance. This indicates that amino resin and thermoplastic copolymer emulsion pavilion formed semi-IPN network and Xinjiang pop dipped in burning match appropriate law. Amino resin premixed flame points of Education and Taiwan, ~ respect to dispersion to spread the fire, the other - aspects of the polar amino resin cover the crime I scratch, plus things that sold milk box Peng, Po Festival base complex Taiwan without demulsification. S. Regret the choice of resistance system flame retardant intumescent fire retardant coating system mainly by expansion of a catalyst composed of carbonized Jing, and blowing agent. Foam components can be decomposed at lower temperatures, combined with the base material to form the foam layer co-carbonization i} Jiao skeleton of the existence of the combustion reaction is usually converted to dehydration, which can be fixed to the skeleton of carbon atoms, led bubble formation are each sheep crowding. According to China's national conditions, choose the appropriate price for the expansion of ammonium polyphosphate and ammonium phosphate catalyst and pentaerythritol as charring agent, melamine flame retardant additives for the blowing agent composition system. . As noted above, FSF_-l water-based intumescent fire retardant coating is superior to the fire and - like fire-resistant coating, once the fork non-toxic,[link widoczny dla zalogowanych], can be used for operation of fire pole and steel materials and decoration.
