摘要
以改性丙烯酸乳液为成膜物质,聚磷酸铵为阻燃剂,季戌四醇为炭化剂,三聚氰胺、氯化石蜡和可膨胀石墨为发泡剂,配以适量的增强剂和填料制备的水性薄型钢结构防火涂料,在涂层厚度为3.0mm时,耐火极限为1.0h,粘结强度为1.08MPa。
The waterborne thin fire retardant coating for steel structure was prepared using modified polyacrylic emulsion as film -forming material, ammonium polyphosphate as fire retardant agent, tetramcthylolmethane as carburetant, trimeric cyanamide, chlorinated paraffin and expandable graphite as foaming agent, companied with right amount of intensifier and filling agent. Its fire-retardant limit was 1.0 h and cohesional strength was 1.08 MPa when the thickness of coating was 3.0 mm.
