摘要:
以乙烯-醋酸乙烯酯共聚物(EVA)边角料、天然橡胶(NR)、相应助剂和填料为主要材料进行共混混炼,再用模压法制备EVA边角料/NR复合发泡材料,研究了模压温度、模压时间和模压压力对复合发泡材料性能的影响. 实验结果表明:模压温度为145 ℃,模压时间为30 min,模压压力为12.5 MPa时,复合发泡材料的综合性能较好. 进一步测定了复合发泡材料的表观密度和发泡倍率曲线,以及硬度和撕裂强度曲线. 实验数据表明,模压温度可改变复合发泡材料的交联程度,模压时间综合影响复合发泡材料的交联程度和泡孔大小,模压压力则与复合发泡材料泡孔生长有关,影响泡孔分布情况.
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.
