Description
技术领域
本发明涉及高分子建筑材料领域，具体涉及一种可用于金属门窗框的增强尼龙复合材料隔热条。
背景技术
近些年来，在建筑市场上那些外观美观、操作灵活且价格合理的节能门窗日益受到用户的青睐，政府也为此制定了一系列的政策以支持节能门窗的发展。而建筑中门窗的隔热是节能设计的重点。众所周知，作为窗框的金属材料导热系数大，这样就使得屋内与屋外的热量交换很快，不利于房屋在夏季时的隔热，同时也不利于房屋在冬季时的保温节能。为了使金属窗框起到隔热节能的作用，必须把内、外层金属用导热系数很低的材料进行隔断。而聚酰胺（尼龙）制作的隔热条正是这样的材料。由于其是热的不良导体，在房屋内外间建立了一个阻止热交换的壁垒，即阻止室外的热进入室内，也阻止室内的热散发到室外。
隔热条需要具备高强度、高热变形温度、低热传导系数、尺寸稳定及耐热氧老化等性能，对尼龙材料的性能要求甚高。现有技术中，通常采用玻纤增强尼龙66复合材料作为隔热型材，其具有较高的机械强度，耐疲劳性和耐磨性能较好。然而，尼龙66吸水性大，制品的尺寸稳定性差，且吸水后容易导致尼龙66隔热条的机械性能下降。此外，尼龙66的耐热性能不够优异，使用范围不够宽，在高低温下使用容易导致材料力学性能的变化。因此，如何制得一种机械性能高、尺寸稳定性好、耐热且使用温度范围宽的尼龙隔热条是目前亟待解决的问题。
发明内容
本发明为解决现有技术中尼龙66隔热条的不足，提供一种增强尼龙复合材料隔热条，由以下组分及重量份配比组成：
尼龙66树脂 100-200份
尼龙410树脂 100-200份
尼龙6T树脂 10-50份
尼龙610树脂 10-50份
玻璃纤维 40-90份
相容剂 5-10份
润滑剂 2-5份
抗氧化剂 1-3份
热稳定剂 1-3份
黑色母 5-10份。
其中，尼龙66树脂、尼龙410树脂、尼龙6T树脂以及尼龙610树脂组成尼龙基料。玻璃纤维优选表面改性玻纤，可以为长玻纤或者短玻纤。相容剂优选马来酸酐接枝PE、马来酸酐接枝POE、马来酸酐接枝EPDM、马来酸酐接枝PP、马来酸酐接枝ABS等。润滑剂优选乙撑双硬脂酰胺、硬脂酸钙、硬脂酸锌等。抗氧化剂优选受阻酚类、亚磷酸酯类抗氧剂。热稳定剂优选有机锡类、金属皂类热稳定剂。
优选地，本发明的增强尼龙复合材料隔热条由以下组分及重量份配比组成：
尼龙66树脂 120-180份
尼龙410树脂 120-180份
尼龙6T树脂 20-40份
尼龙610树脂 20-40份
玻璃纤维 50-80份
相容剂 6-8份
润滑剂 3-5份
抗氧化剂 1-2份
热稳定剂 1-2份
黑色母 6-8份。
更优选地，本发明的增强尼龙复合材料隔热条由以下组分及重量份配比组成：
尼龙66树脂 150-180份
尼龙410树脂 150-180份
尼龙6T树脂 20-30份
尼龙610树脂 20-30份
玻璃纤维 60-80份

热稳定剂 1-2份
黑色母 6-8份。
采用本发明的增强尼龙复合材料隔热条，具备优异的耐热性能和尺寸稳定性，且具有较高的综合力学性能，可广泛应用于各种门窗框的隔热条中。
具体实施方式
为了使本技术领域人员更好地理解本发明方案，下面将对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
实施例1：
将尼龙66树脂100份、尼龙410树脂100份、尼龙6T树脂15份以及尼龙610树脂15份在高混机中高速混合并搅拌均匀，得到尼龙基料；之后，加入5份马来酸酐接枝POE、2份乙撑双硬脂酰胺、1份抗氧剂1010、1份双丁基二氯化锡以及5份黑色母，进行高速混合并搅拌均匀，得预混料。将该预混料加入双螺杆挤出机中，经表面改性处理的50份短切玻纤由玻纤口加入到双螺杆挤出机中，熔融挤出造粒，并干燥。将干燥后的粒料挤塑成型，得到增强尼龙复合材料隔热条。其中，挤出机温度为260-310℃，主机转速为150-300rpm，成型温度为275-315℃。
实施例2：
