                     摘 要:本文制备了一种机器人喷涂用低密度聚氯乙烯焊缝密封胶,分别研究了玻璃微珠种类、
                 组分、加入量、生产工艺对试样密度、流淌性、黏度、抗压性能等的影响。结果表明:试样的密度与玻
                 璃微珠性能有关;玻璃微珠的抗压性能影响现场施工喷涂后试样的最终密度。随玻璃微珠质量分数
                 的增加,试样稳定性提高,密度逐渐变小,但拉伸强度和弯曲试验结果均会下降,流淌性也会受影响。
     健           批量生产时,高速分散和三辊研磨会影响玻璃微珠的降低密度效果,采用预混合及低速循环搅拌方
     康           式使玻璃微珠和物料分散均匀。

                      Abstract:n this paper,a low density polyvinyl chloride sealant for robot was prepared,

                 and the effects of glass beads,content and production process on sample density,lowability,
                                                                                                f
                          c
                 viscosity,ompressive properties were studied. The results showed that the sample density were
                 related to the properties of glass beads,and the compression resistance of glass beads would
                 affect the final density of the sprayed sample. The sample stability increased and the density
                                                                               t
                 decreased  with  the  increase  of  glass  beads  content. However,he  tensile  strength,bending
                 resistance and flowability would also be affected. In mass production,high-speed dispersion
                 and grinding would affect the density reducing effect of glass beads,and the glass beads and
                 materials could be evenly dispersed by pre-mixing and low-speed circulation stirring.
