Description

门窗型材木塑材料
技术领域
本发明涉及一种复合材料,更具体地说,是涉及一种门窗型材木塑材料。本发明还涉及制作这种门窗型材木塑材料。
背景技术
目前市场上的门窗材料大多是采用金属或木材制作的,成本较高,并且大量使用矿产资源或毁坏林木,消费资源较多,有时产品寿命还不长,极易损坏。
在国外有的国家,木粉比例占到总比例的50%以上的木塑制品就可以当做是木制品对社会销售;由于木粉与塑料全部都是废物再利用,所以在提高人们生活质量和水平的同时,对环境保护的意义也是巨大的。
目前中国市场上的木塑材料大多是采用原木的木粉或木纤维与塑料复合的,对伐木毁林有一定推动作用,由于材料强度与加工性不好,仅仅限于挤出一些相对简单、强度不高的产品,同时又由于加工性不好导致的加工费用高企,从而不得不尽力降低材料成本,走上了低质量低价格的恶性循环竞争的路线,对这个行业的损伤是巨大的。
发明内容
本发明的目的在于,提供一种可快速挤出生产门窗型材且具有木料天然气息,可按要求配色的门窗型材木塑材料。
本发明提供的技术方案如下,由以下成分按重量比组成,聚乙烯农膜回收料:20-45%,农作物秸杆粉:51-70%;润滑剂:0.2-2.0%;包覆剂:3-15%;偶联剂:1.0-8.0%;吸湿剂:1.0-5.0%;防老剂:0.5-2.0%;其他助剂:0.1-5.5%.
本发明所述的门窗型材木塑材料的制备方法,包括如下步骤:先将聚乙烯、农作物秸杆粉、润滑剂、包覆剂、偶联剂、吸湿剂、防老剂、其他助剂按照比例称量后在混料机中低速混合5分钟,再经双螺杆挤出机在一定强度剪切的螺杆组合情况下混炼挤出、切粒,经过筛分脱水制得门窗型材木塑材料。
本发明门窗型材木塑材料,在综合机械性能优良、加工性良好的基础上,农作物秸杆粉所占比例远高于50%,用本发明的材料可以快速挤出生产门窗型材,并且产品外观美观,具有木料天然气息,强度高,可按要求配色,同时成本低廉,加工简便,符合环保、经济特征,对人体无害,生产采购方便,提高了竞争力。
具体实施方式
以下是本发明所述的门窗型材木塑材料的最佳实施例,并不因此限定本发明的保护范围。
实施例一,提供一种门窗型材木塑材料,由以下成分按重量比组成:聚乙烯农膜回收料:27.5%,农作物秸杆粉:57%;润滑剂:1.0%;包覆剂:3.0%;偶联剂:5.0%;吸湿剂:3.0%;防老剂:2.0%;其他助剂:1.5%.
本发明的具体步骤为:先将先将聚乙烯、农作物秸杆粉、润滑剂、包覆剂、偶联剂、吸湿剂、防老剂、其他助剂按照比例称量后在混料机中低速混合5分钟,混料机采用低速混合,搅拌叶应与筒壁间隙小于0.5厘米,原辅料混合效果应目视各种粒子和粉末基本均匀,没有明显团块或集聚;双螺杆挤出机使用32长径比,规定强度剪切螺杆组合,设置不高于300转/分钟的转速;采用模面环切方式,经过筛分脱水即制得门窗型材木塑材料。
以上所述,仅为本发明的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本领域的技术人员在本发明所揭露的技术范围内,可不经过创造性劳动想到的变化或替换,都应涵盖在本发明的保护范围之内。因此,本发明的保护范围应该以权利要求书所限定的保护范围为准。
