摘要
为了研究新型钢结构装饰防火涂料的粘结性能与耐火性能,在JKS防火涂料初步配方基础上,改变PVA、可再分散乳胶粉、膨胀蛭石和阻燃剂(氢氧化镁/氢氧化铝=0.32(质量比))的掺量,研究其对JKS涂料性能的影响,利用正交试验得到较好的JKS涂料配方。PVA掺加量为0~2.8%时,JKS涂料粘结强度增加;可再分散乳胶粉的掺加量为3.8%~6.6%时,JKS涂料粘结强度先增加后降低。膨胀蛭石掺加量为13.4%~19.4%时,JKS涂料耐火性能提高;阻燃剂掺加量为10.7%~15.7%时,JKS涂料耐火性能先增加后降低。
In order to study the bond performance and fire resistance of new steel structure ornament fire retardant coatings,based on the preliminary mix proportion of JKS coating, by changing the dosage of PVA, redispersible emulsion powder, expanded vermiculite and fire retardants(Mg(OH)2/Al(OH)3=0.32(mass ratio)), the property of JKS coating was studied, and the better mix proportion of JKS coating was obtained by orthogonal experiment.When the dosage of PVA changes from 0 to 2.8%, the bond strength of JKS coating increases;when the dosage of redispersible emulsion powder changes from 3.8% to 6.6%, the bond strength of JKS coating increases first and then decreases;when the dosage of expanded vermiculite changes from 13.4% to 19.4%, the fireproof property of JKS coating increases;when the dosage of fire retardants changes from 10.7% to 15.7%, the fireproof property of JKS coating increases first and then decreases.
