Description

一种碳铝复合散热器用碳塑复合材料及其制备工艺
技术领域
本发明涉及导热高分子材料制备领域，具体是指一种碳铝复合散热器用碳塑复合材料及其制备工艺。
背景技术
家用散热器也称为暖气片，是一种采暖为主的采暖设备。主要在冬天寒冷的北方地区使用，具有保暖的作用，以前多使用铸铁暖气片，现在已经发展出了更多材质的暖气片。铸铁暖气片已经逐步退出了市场舞台，钢制暖气片、铜铝复合散热器、铝制暖气片等新型暖气片无论从材质上还是制作工艺上都优于铸铁散热器，但是即便如此，散热器因为是金属制成的，使用久了就会出现腐蚀漏水，使用寿命短，而且生产的时候投入成本高。
发明内容

为解决上述技术问题，本发明提供的技术方案为：
一种碳铝复合散热器用碳塑复合材料，包括以下重量份原料:聚丙烯34份、聚乙烯8份、聚烯烃7份、石墨粉50份、马来酸酐接枝料配方2份、铝酸酯偶联剂1份、炭黑3份及抗氧剂0.35份。
作为改进，所述聚丙烯为大连石化生产，型号为T03的均聚聚丙烯，所述聚乙烯为燕山化工生产，型号为5502LW的聚乙烯，所述聚烯烃选用大庆化工的型号为8150的聚烯烃，所述石墨粉选用青岛恒利得生产型号为F-1的2000目的石墨粉，所述马来酸酐接枝料配方选用PP-g-MAH系列，所述铝酸酯偶联剂选用福州师大研制，型号为DL-411-E的铝酸酯偶联剂，所述抗氧剂包括0.2份迪龙生产且型号为1010的抗氧剂和0.15份北京极易化工生产且型号为168的抗氧剂。
作为改进，所述马来酸酐接枝料配方包括以下所占马来酸酐接枝料配方重量份的原料：大连石化生产牌号为T30S的聚丙烯粒料100份、宝利龙牌号为A1018的马来酸酐4份、跃江化工生产且牌号为80-43-3的过氧化异丙苯0.3份及跃龙化工生产且牌号为6683-19-8的抗氧剂 0.4份。
一种应用于权利要求1所述的碳铝复合散热器用碳塑复合材料的制备工艺，包括以下具体步骤：将聚丙烯、聚乙烯、聚烯烃、石墨粉、马来酸酐接枝料配方、铝酸酯偶联剂及抗氧剂分别称重，将聚丙烯置于80℃干燥箱中干燥2h，然后加入石墨粉、炭黑、马来酸酐接枝料配方、铝酸酯偶联剂及抗氧剂，简单混合经密炼机密炼，经挤出机混炼挤出造粒，将混合粒料和聚乙烯放入80℃干燥箱中干燥3h，将混合粒料和聚烯烃预配混料简单混合5min，放入挤出机二次混合造粒，挤出机温度设为140—205℃，挤出产量固定为4.2kg/h，设定挤出机主螺杆转速为48r/min，将粒料干燥2h，干燥温度80℃，用注射机注塑制样用于各种测试。
