模压条件对EVA边角料/天然橡胶复合发泡材料性能的影响
Effect of Molding Conditions on Properties of Poly (Ethylene-Co-Vinyl Acetate)Scraps/Natural Rubber Composite Foam
摘要
Abstract
The mixture of poly(ethylene-co-vinyl acetate)(EVA) scraps/natural rubber(NR)was prepared by the melt-mixing firstly in a two-roll mill using the scraps of industrial EVA foams,NR,the additives and fillers as the main raw materials. Subsequently,the EVA scraps/NR composite foams were prepared by the compression molding method using the EVA/NR mixture in a mold. The influences of molding temperature, molding time and molding pressure on the physical and mechanical properties of EVA/NR composite foams were also investigated. The optimum preparation conditions of composite foams were confirmed at the molding temperature of 145 ℃,molding time of 30 min and molding pressure of 12.5 MPa. The apparent density, foaming ratio,hardness and tear strength of composite foams were further measured herein. The experimental data indicate that the molding temperature can change the crosslinking degree of the composite foams and the molding time can affect the crosslinking degree and size of composite foams. Meanwhile,the molding pressure is related to the bubble growth of the composite foams,which affects the distribution of the bubble.关键词
