具体实施方式
下面将结合本发明实施例中的附图,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,都属于本发明保护的范围。
请参阅附图,本发明为了一种耐火玻璃钢复合板,包括耐火玻璃钢层、防裂层、表层、带孔布、底层,所述耐火玻璃钢层一侧通过胶黏剂粘合防裂层,所述防裂层上设置表层,所述耐火玻璃钢层另一侧敷设有带孔布,所述带孔布上涂覆所述底层;所述防裂层为碳纤维加强筋网;所述表层为耐磨复合层;所述底层为涂覆耐磨复合层。
所述耐火玻璃钢层包括,不饱和聚酯树脂、酚醛树脂、环氧树脂、玻璃纤维、硅烷偶联剂、碳化硅、氧化铝、石英砂、阻燃剂、金属填料。
玻璃纤维是叶腊石、石英砂、石灰石、白云石、硼钙石、硼镁石七种矿石为原料经高温熔制、拉丝、络纱、织布等工艺制造成的,具有耐热性强、抗腐蚀性好、抗拉强度大,机械强度高,用作复合材料中的增强材料。
硅烷偶联剂用于玻璃纤维增强塑料,硅烷氧基对无机物具有反应性,有机官能基对有机物具有反应性或相容性,当硅烷偶联剂介于无机和有机界面之间,可形成有机基体-硅烷偶联剂-无机基体的结合层,改善无机填料与树脂之间的相容性;能改善填料在树脂中的分散性及粘合力,改善玻璃纤维和树脂的粘合性能,提高玻璃纤维增强复合材料的强度;硅烷偶联剂还能与界面发生化学反应,使耐火玻璃钢层与胶黏剂更好的结合,从而提高胶接强度。
碳化硅、氧化铝、石英砂具有较好的耐火耐高温性能。
阻燃剂主要是针对高分子材料的阻燃设计的。通过添加型阻燃剂经由机械混合方法加入到聚合物中,使耐火玻璃钢层具有阻燃性的。目前添加型阻燃剂主要有有机阻燃剂和无机阻燃剂,卤系阻燃剂(有机氯化物和有机溴化物)和非卤。有机是以溴系、磷氮系、氮系和红磷及化合物为代表的一些阻燃剂,无机主要是三氧化二锑、氢氧化镁、氢氧化铝,硅系等阻燃体系。本实施例中,选用含卤素的阻燃剂溴系列阻燃剂,在热塑性树脂中具备阻燃效率高,制得的材料力学性能好,如十溴二苯乙烷。
表层和底层的耐磨复合层包含:环氧树脂、酚醛树脂、玻璃纤维增强不饱和聚酯、聚四氟乙烯纤维、二氧化钛、陶瓷纤维、碳化硅、紫外线吸收剂。
不仅具有较高的耐磨性能,还通过采用不饱和聚酯树脂及其他辅助材料做为固化体系,使用玻璃纤维、聚四氟乙烯、陶瓷纤维做为增强材料,生产高性能复合线性材料,通过合理的配方体系提高产品的强度。添加的紫外线吸收剂是一种光稳定剂,能吸收阳光及荧光光源中的紫外线部分,而本身不发生变化。由于太阳光线中含有大量对有色物体有害的紫外光,其波长约290-460纳米,这些有害的紫外光通过化学上的氧化还原作用,使颜色分子最后分解褪色。使用紫外线吸收剂对受保护的物体实施有效的防止,或削弱其对颜色的破坏。紫外线吸收剂热稳定性好,即使在加工中也不会因热而变化,热挥发性小,化学稳定性好;不与制品中材料组分发生不利反应;混溶性好,可均匀地分散在材料中;且不溶或难溶于水,在表层和底层的耐磨复合层中提升玻璃钢复合板起到保护作用。
