Description
技术领域
本发明涉及高分子材料技术领域,特别是涉及一种呋喃二酸基聚酰胺树脂及其制备方法和一种聚酰胺模塑组合物。
背景技术
传统聚酰胺单体主要来源于石油,现如今人类面临着石油资源消耗过量、二氧化碳排放剧增、温室效应加剧的问题。降低石油基单体用量,可抑制二氧化碳排放,防止温室效应,解决环境污染和资源紧张问题,构建可持续发展社会。生物基耐高温聚酰胺,主要是指来自生物基脂肪族二胺或生物基芳环二酸聚合而成的聚酰胺,生物基单体通常由动植物提取,一方面可实现绿色可持续发展,另一方面可使耐高温聚酰胺产品更加多元化,满足更加细分行业的需求。
经市场调研和分析,生物基单体癸二胺、戊二胺和呋喃二甲酸被认为是最有可能实现实质性突破的生物基耐高温聚酰胺单体材料。癸二胺来源于植物蓖麻油,在国内已实现量产,但其售价较高,市场竞争力较弱。戊二胺来源于谷氨酸发酵,在国内实现量产,价格较低,具有良好的市场竞争力。呋喃二甲酸是目前已知的、唯一的、近期最有可能实现产业化的生物基芳环二酸单体,目前国内外在呋喃二甲酸的研究均处于中试研发阶段。
中国专利申请CN106536187A公开了一种基于呋喃的聚酰胺,采用了生物基单体2,5-呋喃二羧酸,二胺为脂肪族二胺、芳族二胺等,具有良好的阻隔气体的优点。但是,其气体阻隔性主要是通过聚合短碳链二胺(1,3-丙二胺、)来提升酰胺键密度来实现的。但是该呋喃聚酰胺的阻燃性较差。

(3)聚酰胺吸水率:将样品注塑成20 mm× 20 mm× 2 mm的样板,其重量记为a0。然后将其置于95℃水中240 h后,称量其重量记为a1。则吸水率=(a1-a0)/a0*100%。
(4)聚酰胺收缩率:将样品注塑成20mm× 10mm× 2mm的样板,然后将其置于95℃水中240h后,按照ISO 294-4-2018标准测试其吸水后的收缩率。
