【摘要】：通过考察几种增塑剂用于预涂饰装饰纸浸渍树脂的使用效果,探索聚丙烯酸酯作为氨基浸渍树脂增塑剂的可能性。研究增塑剂对浸渍树脂适用期的影响及对预涂饰装饰纸预固化度、柔韧性和耐潮性的影响。结果表明:聚丙烯酸酯能促进和参与氨基树脂的交联反应,提高预涂饰装饰纸的各种性能。当增塑剂的用量达到树脂量的50％以上时,即使不加固化剂,浸渍纸预固化度也可达到70％以上而满足工艺要求;当增塑剂为树脂量的40％～50％时,纸张的柔韧性明显提高,其弯曲半径达到3mm;当氨基树脂中加入的增塑剂量与树脂量相同时,浸渍纸吸湿率可降低30％左右,耐潮性明显增强。增塑剂也会缩短浸渍树脂的适用期,当增塑剂为树脂量的30％～50％时,适用期最短,加入抑制剂后方可满足生产工艺要求的适用期。
[Abstract]:The possibility of polyacrylate as a plasticizer of amino impregnated resin was explored by investigating the effect of several plasticizers used in precoating decorative paper impregnating resin. The effect of plasticizer on the application period of impregnated resin and on the precuring degree, flexibility and moisture resistance of precoated decorative paper was studied. The results showed that polyacrylate could promote and participate in the crosslinking reaction of amino resin and improve the properties of precoated decorative paper. When the amount of plasticizer reached more than 50% of the resin content, the precuring degree of impregnated paper could reach more than 70% without the addition of curing agent, and when the amount of plasticizer was 40 ~ 50%, the flexibility of the paper was obviously improved. When the amount of plasticizer added in amino resin is the same as that of resin, the moisture absorption rate of impregnated paper can be reduced by about 30%, and the moisture resistance of impregnated paper is obviously enhanced. Plasticizer can also shorten the suitable period of impregnating resin. When the plasticizer is 30 ~ 50 percent of resin, the application period is the shortest, and the suitable period after adding inhibitor can meet the requirements of production process.
