The invention is a kind of insulating pulp for producing insulating layer of vacuum fluorescence monitor and the manufacturing method. It includes insulating glass powder, organic carrier and high temperature inorganic black dyes; the insulating glass powder is dispersed into the organic carrier evenly, the organic carrier is liquor by dissolving the resin into the organic solvent, and adds in the high temperature inorganic black dyes, forms the plaster compound. The method is: mixing the glass powder and black dyes evenly according to the type of black dyes and the weight percentage; grinds them compound until the average particle size is less than 5 um, the maxim particle size is not more than 10 um; mixing the compound of the glass powder and black dyes and the organic carrier evenly; finally, then grinds them in the three-roll grinder until its fineness is less than 15 um. The insulating layer image resolution is good; it has no holes and micro-crack, the insulating electricity density is high. 一种用于真空荧光显示器绝缘层制作的绝缘浆料及其制备方法，它包括绝缘玻璃质粉体、有机载体及高温无机黑颜料，将该绝缘玻璃质粉体均匀分散在有机载体中，有机载体为由树脂溶于有机溶剂形成的溶液，并且添加高温无机黑颜料，形成膏状组合物。制备方法是：根据黑颜料的品种及所占重量百分比，将玻璃质粉体和黑颜料均匀混合；再将获得的上述混合物细磨至粉体平均粒径小于5μm，最大颗粒粒径不大于10μm；在浆料搅拌机中将玻璃粉黑颜料的混合物和有机载体均匀混合；最后，将获得的混合浆料在三辊研磨机上研磨分散至细度小于15μm。利用本发明制作的绝缘层图形分辨率良好、宏观无针孔和微裂纹、黑色玻璃光泽、绝缘电气强度高。
