摘要
以胶凝剂水玻璃、交联剂小苏打、三种发泡剂为原料制备一种高稳与高抗烧性的凝胶泡沫基础配方,采用单因素交联试验与四因素三水平正交试验研究水玻璃交联体系与复配发泡剂,并分析了水玻璃交联体系在用不同交联剂时对胶凝结果的影响,发泡剂各组分对发泡体积和半衰期的影响,最后采用小尺度抗烧试验评价凝胶泡沫的抗烧性能。结果表明,胶凝剂水玻璃的质量分数为9.00%,交联剂碳酸氢钠的质量分数为3.50%,CTAB、AES、CAB-35三种组分的质量分数分别为0.1%、0.12%、0.6%时,基础配方发泡剂稳定性能提升了270%,抗烧性能与两相泡沫相比提升了53%。
A kind of foamed gel with high stability and good burn resistance performance was prepared by using thickener water-glass, cross-linking agent bicarb and three foaming agents as raw materials. Single factor cross-linking experiment and four-factor three-level orthogonal experiment were used to study water-glass-gel system and the foaming agent, and then effect of different cross-linking agent on gelling results was analyzed as well as effect of different components of foaming agent on the foaming volume and half life. Finally the anti-burning performance of the gel foam was investigated by the anti-burning test. The results show that when the mass fraction of gelling agent water-glass, cross-linking agent, CTAB, AES, CAB-35 is 9.00%, 3.50%, 0.1%, 0.12% and 0.6%, the stability of the foundation formula foaming agent can be improved by 270%, the burn resistance performance of the formula can be improved by 53% compared with two-phase foam.
