摘　　要：通过改变注塑工艺参数,研究了注塑工艺对高抗冲聚苯乙烯(HIPS)产品的光泽度的影响。结果表明:随着熔体温度的升高,产品的光泽度明显提高;当模具温度为65℃时,产品的光泽度达到86.6%,可以满足厂家对高光制品的需求;当注射压力控制在7.5MPa左右时,产品的光泽度最好;随着注射速度的增加,产品的光泽度不断增加;当保压压力在7 MPa左右时,产品的光泽度最好;延长保压时间,可提高产品的光泽度,当保压时间超过20s后,产品的光泽度几乎不变。bThe influence of injection molding technology on the glossiness of high impact polystyrene（HIPS）products was investigated by changing the injection process parameters.The results show that with the increase of melt temperature,the glossiness of products was obviously increased.When the mould temperature was 65℃,the glossiness of products reached 86.6%,can meet the demand of high gloss products manufacturers.When the injection pressure was about7.5MPa,the glossiness of products is the best.With the increase of injection speed,the glossiness of the product increased continuously.When the holding pressure is about 7 MPa,the product has the best glossiness.Prolonging the holding time could improve the glossiness of products.When the holding time is over 20 s,the glossiness of products was almost unchanged.
