【摘要】：探究了复合泡沫保温板最佳条件下的制备工艺,结果表明,聚苯乙烯与酚醛树脂作为两种常用的泡沫保温材料和一定的助剂混合均匀后,可制备出一种新型复合泡沫保温板同时具备二者的优点,从而发挥出更优异的理化性能;酚醛树脂和其他助剂的用量一定,通过改变聚苯乙烯的用量来调整其比例时,随着聚苯乙烯含量下降,其表观密度也呈现下降趋势,其导热系数呈现先降后增再降的曲线趋势,其压缩强度呈现先降后增的趋势;复合泡沫板的成型温度不断升高,其导热系数呈现出先降再升的趋势,其压缩强度呈现出先升再降的趋势,其气泡形态在60~70℃时呈现最好的状态。
[Abstract]:The preparation process of composite foam insulation board under the optimum conditions was investigated. The results showed that polystyrene and phenolic resin were mixed evenly as two commonly used foam insulation materials and some additives. A new type of composite foam insulation board can be prepared with the advantages of both, thus giving play to better physical and chemical properties. When the amount of phenolic resin and other additives is fixed, the proportion of phenolic resin and other additives can be adjusted by changing the amount of polystyrene. With the decrease of polystyrene content, the apparent density also showed a downward trend, its thermal conductivity decreased first and then increased, its compression strength decreased first and then increased, and the molding temperature of composite foam plate increased continuously. The thermal conductivity shows the tendency of first decreasing and then rising, and the compression strength is rising first and then decreasing, and the bubble morphology is the best at 6070 鈩，
