技术介绍
稳定剂特别是钙锌稳定剂,为PVC树脂制品中的添加剂。钙锌稳定剂通常分为:固体钙锌稳定剂与液体钙锌稳定剂。钙锌稳定剂是由钙盐、锌盐、润滑剂、抗氧剂等为主要组分采用特殊复合工艺而合成。它不但可以取代铅镉盐类和有机锡类等有毒稳定剂,而且具有相当好的热稳定性、光稳定性和透明性及着色力。实践证明,在PVC树脂制品中,加工性能好,热稳定作用相当于铅盐类稳定剂,是一种良好的无毒稳定剂。钙锌稳定剂生产步骤为:1:将粗羊毛酸在40-100℃下熔融。2:将氢氧化钠在50-100℃的乙醇水溶液中溶解,乙醇-水溶液为乙醇体积浓度80%-85%的乙醇-水混合液。3:将步骤1熔融的羊毛酸逐渐加入到步骤2的溶液中,在50-100℃下搅拌皂化反应为1-4h,反应原理为RCOOH+NaOH→RCOONa+H2O,其中RCOOH为羊毛酸。4:将反应液趁热调整PH值为7-9,然后降温至40-70℃,先加入一定体积比的反应液和水(体积比为1:9-1:4),然后顺次加入氯化钙和七水硫酸锌,反应1-4h后产物经抽虑、醇洗、水洗、烘干研碎后即为成品固体钙锌稳定剂。钙锌稳定剂包括液体和固体两种形式,为了方便运输及使用,固体钙锌稳定剂使用范围更广,在烘干并粉碎后的钙锌稳定剂一般需要进行压片,压片后的钙锌稳定剂更加方便运输和使用,现阶段的压片机大多为制药厂进行设计,对于药剂的压制不需要太高的压力,片剂成型度好,也无需后续筛分,这对 ...
