采用新工艺使形成凝胶的阳离子淀粉颗粒均匀包覆沉淀碳酸钙(PCC)表面，得到一种新型的改 性PCC,并对改性PCC的各个性质尤其对纸页的增强效果进行研究。探索两种PCC的改性方法，一种是 使用糊化好的高浓度淀粉溶液包裹PCC；另一种是先混合未糊化淀粉乳液和PCC，再蒸煮混合物。结 果表明：第1种方法淀粉溶解率较低，并且淀粉糊化浓度对淀粉溶解和手抄片各种性质有较大影响。 分别对糊化淀粉溶液质量分数为20 %、30 %、40 %、50 %、60 %的淀粉进行试验比较，发现糊化淀 粉溶液质量分数30 %改性PCC不仅具有均匀的颗粒大小，较低的淀粉溶解率，而且抗张指数提高41.1 %，耐破指数提高50 %,表面强度提高45.3 %，灰分提高37.5 %。
Abstract
A new kind of modified PCC was prepared by a new technology to wrap PCC with a gelled cationic starch, and the properties of modified PCC , especially in the aspect of strengthening effect of paper were investigated. Two methods for PCC modification were explored, one was to wrap PCC with cooked starch at high solid content, and the another was to mix the PPC with ungelled starch first and then cook the mixture. The result indicated that the dissolution rate of starch in the first method was low, and the concentration of gelled starch gave great influence on both the dissolution of starch and the properties of paper handsheet. Comparing the PCC obtained from the different usage of starch from 20%, 30%, 40%, 50% and 60%, it was found that the modified PPC from 30% of starch has the following advantages: uniform particle size, low dissolution rate of starch. Furthermore, the tensile index, burst index, surface strength, and ash content were increased by 41.1%, 50%, 45.3%, and 37.5%, respectively.
