ABS微孔发泡材料气体扩散行为分析
Analysis on Gas Diffusion Behavior of ABS Microcellular Foam Material
摘要
Abstract
Microcellular acrylonitrile-butadiene-styrene (ABS) foam was prepared by chemical cross-linked compression molding. The effects of foam temperature, foam pressure and foam time on the gas diffusion behavior and the foam structure of ABS microcellular foam material. The results show that: gas absorption increases firstly and then decreases with the increasing of the foaming temperature, foaming pressure and foaming time. With the increasing of gas absorption, cell size of the products decreases gradually, while the cell density increases gradually. To increase the gas absorption is beneficial to improving the foaming effect. When the foaming temperature is 170℃, foaming pressure is 10 MPa and foaming time is 12 min, the cell density is 2.87×108 cells/cm3, which meets the requirements of microcellular foam material.关键词
