Description

一种复合板材用热熔胶及其制备方法
技术领域
    本发明涉及热熔胶领域，具体涉及一种复合板材用热熔胶及其制备方法。
背景技术
热熔胶是以热塑性树脂或弹性体为基料，添加增黏剂、增塑剂、抗氧化剂、阻燃剂及填料，经熔融混合而成的固体状粘合剂。与热固型、溶剂型和水基型胶粘剂相比具有很多优越性，所以从20世纪50年代至今，热熔胶已经在许多领域得到了快速发展，尤其在印刷、包装等行业已用热熔胶取代钉装和线装，并开始用于建筑、飞机、舰船和汽车内装饰等领域。
现有市场上热熔胶相关产品较多，但随着温度的变化，传统热熔胶的性能也在变化，当温度升到一定高温或降到一定低温热熔胶的性能都会降低，对材料的结合强度削弱，最终影响材料的强度。
发明内容
本发明提供一种复合板材用热熔胶，本发明的热熔胶，粘结性强、耐低温、耐水性好、防腐蚀。 
本发明采用的技术方案如下：
一种复合板材用热熔胶，其特征在于，由下列重量份的组分制备而成：
PE聚乙烯90-95、SBS苯乙烯-丁二烯-苯乙烯嵌段共聚物 5-8、溴化丁基橡胶增粘树脂8-10、乙撑双硬脂酰胺1-2、石蜡5-8、轻质碳酸钙10-12、抗氧剂736 0.1-0.3、 抗氧剂626 0.2-0.4、抗氧剂1680.1-0.2、乙酰柠檬酸三乙酯8-9、衣康酸酯1-2，
其中， 所述溴化丁基橡胶增粘树脂由下列方法制备而得： 
（1）将15-18重量份溴化丁基橡胶、24-28重量份二甲苯、6-9重量份凹凸棒土、0.2-0.3重量份的交联剂 TAIC混合，在80-110℃下，反应2-3小时；
  （2）然后加入聚合松香、防老剂TPPD ，在130-150℃下，反应2-3小时，要求，聚合松香、溴化丁基橡胶、防老剂TPPD三者的重量比为:100:15-18：0.5-0.6；
  （3）再加入苯基三乙氧基硅烷、二茂铁在140-175℃下反应1-2小时，要求，聚合松香、苯基三乙氧基硅烷、二茂铁的重量比为100:1-0.9:1-2；
  （4）最后蒸馏除去二甲苯溶剂，得到溴化丁基橡胶增粘树脂。
所述的复合板材热熔胶的制备方法，其特征在于，包括以下步骤： 
（1）首先制备溴化丁基橡胶增粘树脂；
（2）按配方比例称取各配方原料，将原料倒入高速搅拌机混合均匀；
（3）搅拌均匀的混合料由双螺杆挤出机中挤出造粒，设定机筒加热温度为140-168℃，口模温度为168-195℃，螺杆转速为17-60rpm，加料转速为7-40rpm，待物料从口模挤出后经水槽冷却后切料，得到成品热熔胶。
与现有技术相比，本发明具有如下有益效果：
本发明的热熔胶粘结性强，在配方中添加了自制的橡胶增粘树脂，使制得的热熔胶的粘结性能增强，同时具有很好的耐低温性、耐候性，抗老化能力强、韧性好、耐水性好。
