摘　　要：研究新型抗沉淀剂KM-S研磨碳酸钙和半补强炭黑以及用于胶乳混合分散体的分散效果。结果表明:抗沉淀剂KM-S具有优良的分散作用,研磨碳酸钙能显著减小分散体沉降量;研磨半补强炭黑,分散体总固体质量分数最高可达到0.30;研磨混合分散体配制的胶乳粘度低、稳定性好,制备的气球物理性能优良。In this paper, a new anti-settling agent KM-S was applied to modify calcium carbonate and semi-reinforcing carbon black by grinding, and the dispersion of modified fillers in rubber latex was studied. It was found that anti-settling agent KM-S was an excellent filler dispersion aid. The settlement of calcium carbonate after anti-settling agent KM-S treatment was reduced significantly and the addition level of carbon black after anti-settling agent KM-S treatment reached 0.30. The rubber latex with addition of anti-settling agent KM-S modified filler had low viscosity and good stability,and the physical properties of the balloon prepared from the latex were good.
