    • The present invention relates to a manufacturing method for a rubber band, comprising preparing a production raw material: mixing and stirring by weight percent 50%-80% vinyl-terminated polydimethylmethylvinylsiloxane, 19%-40% silica and 1%-10% hydroxy-terminated polydimethylsiloxane into a paste ready for use; feeding the aforementioned production raw material into forming molds to produce rough rubber bands; soaking the rough rubber bands in a surface treatment solution for a certain time period, wherein the surface treatment solution comprises by weight percent 40%-50% methyl vinyl silicone rubber, 30%-35% deodorized kerosene, 7%-10% oxygen-containing silicon oil and 10%-20% silicon powder; taking the soaked rough rubber bands out of the solution after soaking and baking them at a high temperature of 200-250° C. A rubber band made according to the above-described method has good elasticity, a non-slip property, no cracks after stretching, is not easy to be broken, durable, non-toxic, environmentally friendly and nondeformable for multiple times of use.
    • 橡胶带的制造方法技术领域本发明涉及一种橡胶带的制造方法,其包括制备生产原料:以重量百分比计的50%-80%乙烯基封端的聚二甲基甲基乙烯基硅氧烷,19%-40%二氧化硅和1%-10%羟基 - 封端的聚二甲基硅氧烷制成糊状物即可使用; 将上述生产原料进料到成型模具中以产生粗糙的橡胶带; 将粗糙的橡胶条在表面处理溶液中浸泡一定时间,其中表面处理溶液包含40%-50%的甲基乙烯基硅橡胶,30%-35%的除臭煤油,7%-10%的氧气 - 含硅油和10%-20%硅粉; 在200-250℃的高温下浸泡并烘烤之后,将浸泡的粗糙橡胶带从溶液中取出。根据上述方法制成的橡胶带具有良好的弹性,防滑性,无裂纹 拉伸,不易破碎,耐用,无毒,环保,不可变形多次使用。
