技术领域
本发明涉及一种橡塑增强剂的制备,具体是指用于添加在橡塑材料中来提高橡塑制品机械强度的一种减轻模具磨损的改性橡塑增强剂的制备方法。
背景技术
橡塑增强剂是一种能够提高橡塑制品机械强度的添加剂,简称增强剂;现有技术的增强剂要么单纯采用矽丽粉,要么单纯采用叶腊石粉体;矽丽粉是一种含有粒状石英和片状高岭土的天然矿物的粉体;叶腊石粉体亦是一种含有石英的天然矿物的粉体;由于石英的硬度高且仅次于金刚石,因此,单纯采用矽丽粉或者单纯采用叶腊石粉体作为橡塑材料的增强剂,橡塑材料在通过模具成型制造橡塑制品时,由于石英颗粒的作用,模具的磨损很大很快,为了确保橡塑制品的质量,不得已而频繁地更新模具,致使橡塑制品的成本增高,因此,现有技术存在模具磨损严重、制品成本居高的问题与不足。
发明内容
针对上述现有技术存在的问题与不足,本发明采用由叶腊石粉体、沸石粉体和硅藻土粉体构成的组份配方,并配套以制备工艺,对叶腊石系的增强剂进行改性的技术方案,提供一种减轻模具磨损的改性橡塑增强剂的制备方法,旨在制备出改性橡塑增强剂,使橡塑制品的成型制造,达到减轻模具磨损和降低制品成本的目的。
本发明的目的是这样实现的:一种减轻模具磨损的改性橡塑增强剂的制备方法,包括组份配方和制备工艺,其中,
所述的组份配方为:
A原料:叶腊石粉体,粒度5~12微米,40%;所述叶腊石粉体的成分要求为:SiO2,65~70%;Al2O3,20~25%;其它余量;
B原料:沸石粉体,粒度5~12微米,40%;所述沸石粉体的成分要求为:SiO2,60~65%;Al2O3,25~30%;其他余量;

混合助剂:硬脂酸,5%;聚乙烯蜡,1%;所述聚乙烯蜡的分子量要求为:1000~2000;钛酸酯,2%;
偶联剂:γ-氨丙基三乙氧基硅烷,2%;
组份配方单位为重量百分比;
所述的制备工艺为混合:
将配方中的A原料、B原料和C原料依次投入高速混合机中进行混合,转速3000转/分钟,混合用时5分钟,获得混合粉体;之后,将配方中的混合助剂和偶联剂加入到高速混合机中与所述混合粉体混合,对所述混合粉体进行活化改性,控制所述混合粉体温度102℃~105℃,转速3000转/分钟,混合用时10分钟;获得减轻模具磨损的改性橡塑增强剂成品,装袋入库。
