通过湿纸力增强乳液(SQR)与松香乳液的共混,开发了抗水型湿纸力增强乳液(SQJ),并研究了乳液的质量比,使用浓度和助剂等对SQJ湿纸力增强和抗水作用的影响。结果表明:当SQR与松香乳液的质量比为4∶6、共混乳液的使用量为1.2%、和添加10%的硫酸铝作为助剂时,纸张的湿强度和Cobb值分别提高了30.8%和73%,明显优于传统湿强剂PAE
Through the blending of wet strength paper (SQR) and rosin emulsion, a water-resistant wet paper force-enhanced emulsion (SQJ) was developed. The effects of emulsion mass ratio, concentration and additives on SQJ wet paper strength And the effect of water resistance. The results showed that when the mass ratio of SQR to rosin emulsion was 4: 6, the amount of blended emulsion was 1.2%, and the addition of 10% aluminum sulfate as auxiliary, the wet strength and Cobb value of paper increased by 30.8% And 73%, significantly better than the traditional wet strength agent PAE
