The optimal formulation of phenolic foam was obtained as the following:5phr of flame retardant,3phr surfactant,12phr of foaming agent,1phr of toughening agent,the ratio of p-toluenesulfonic acid/phosphoric acid was 7:5. The better foaming temperature was 75°C ~78°C. The optimization of flame retardants was conducted in the paper. Finally,the flame retardant was selected as liquid oligomeric bisphenyl A bis(diphenyl phosphate),and its dosage was 5%. The flammabilities of phonolic foams prepared in this paper were studied using cone calorimeter. The results indicated that by the addition of halogen-free flame retardant,the heat releasing rate (HRR) and the total smoking amount of the foam plastics decreased greatly,which indicated that the flame retar-dance of the foam was increased further.

    • 摘要: 针对酚醛泡沫塑料脆性大和强度低的缺点,采用双氰胺作为改性剂,对酚醛树脂及其泡沫塑料进行了改性研究,并将改性前后两种泡沫塑料的性能进行了对比.采用傅立叶变换红外光谱对酚醛树脂进行了结构表征,通过粉化率、冲击强度和压缩强度测试分析了改性酚醛泡沫塑料的脆性和力学性能,通过热失重分析了改性酚醛泡沫塑料的热稳定性,并采用极限氧指数仪测定了改性酚醛泡沫塑料的阻燃性能.结果显示,当加入的双氰胺用量为苯酚质量的3%时,改性酚醛泡沫塑料的综合性能最好,其压缩强度达到0.046 MPa,冲击强度达到3.36 kJ/m2,粉化率低至2.13%,极限氧指数达到38.5%.相对于纯酚醛泡沫塑料,双氰胺改性酚醛泡沫塑料的力学性能有所提升,脆性明显改善.在热稳定性方面,纯酚醛泡沫塑料在340°C时已明显失重,而3%双氰胺改性酚醛泡沫塑料在370°C后才开始快速失重,热稳定性更好.随着双氰胺用量的增加,改性酚醛泡沫塑料的极限氧指数增大,阻燃性能有所提高.

The influences of KH–560 concent on properties of phenolic foam plastics were investigated. The resules show that the properties of the modified phenolic foam plastics are significantly improved. When the mass fraction of KH–560(relative to the mass in the reaction of phenol) is 7%,the compression strength,impact strength and limiting oxygen index reaches the maximum values,are improved by 37%,68%,3.8%respectively,compared with pure phenolic foam plastics. KH–560,when the addition amount of 7%of the modified phenolic foam reach maximum compression strength,impact strength and flame retardancy,the pulverization rate has minimum value(1.6%) when the mass fraction of KH–560 is 5%. Thermogravimetric analysis indicated that the thermal stabilities of the modified phenolic foam plastics is slightly decreased,the weight residuals increase 1%~3%at 500°C,compared with pure phenolic foam plastics. The modified phenolic foam plastics still keep excellent thermostability.%以硅烷偶联剂KH–560作为增韧剂,制备了KH–560改性酚醛泡沫塑料,研究了KH–560含量对酚醛泡沫塑料性能的影响。结果表明,添加KH–560制备的改性酚醛泡沫塑料的性能得到明显提高,当KH–560质量分数(相对于参加反应苯酚的质量)为7%时,改性酚醛泡沫塑料的压缩强度、冲击强度和阻燃性均达到最大值,同纯酚醛泡沫塑料相比,分别提高了37%,68%和3.8%。当KH–560质量分数为5%时,改性酚醛泡沫塑料的粉化率最小,为1.6%。热失重分析结果表明,改性酚醛泡沫的热稳定性仅稍有降低,500°C时的质量保持率较纯酚醛泡沫塑料提高1%~3%,仍然保持优良的热稳定性。
