Description

一种高强度阻燃型复合玻璃钢管
技术领域
本发明涉及玻璃钢技术领域，具体为一种高强度阻燃型复合玻璃钢管。
背景技术
玻璃钢学名纤维增强塑料，俗称FRP，即纤维增强复合塑料。根据采用的纤维不同分为玻璃纤维增强复合塑料（GFRP），碳纤维增强复合塑料（CFRP），硼纤维增强复合塑料等。它是以玻璃纤维及其制品（玻璃布、带、毡、纱等）作为增强材料，以合成树脂作基体材料的一种复合材料。纤维增强复合材料是由增强纤维和基体组成。纤维（或晶须）的直径很小，一般在10μm以下，缺陷较少又较小，断裂应变约为千分之三十以内，是脆性材料，易损伤、断裂和受到腐蚀。基体相对于纤维来说，强度、模量都要低很多，但可以经受住大的应变，往往具有粘弹性和弹塑性，是韧性材料。
我国有90%以上的FRP产品是手糊法生产的，其他有模压法、缠绕法、层压法等。日本的手糊法仍占50%。从世界各国来看，手糊法仍占相当比重，说明它仍有生命力。手糊法的特点是用湿态树脂成型，设备简单，费用少，一次能糊10m以上的整体产品。缺点是机械化程度低，生产周期长，质量不稳定。我国从国外引进了挤拉、喷涂、缠绕等工艺设备，随着FRP工业的发展，新的工艺方法将会不断出现。
玻璃钢由于它的特殊性质已经运用到各种行业，随着玻璃钢运用的越来越广泛，玻璃钢的质量及其性能也需要提高，以避免浪费资源节约成本。玻璃具有硬但易碎，具有很好的透明性以及耐高温、耐腐蚀等性能；同时钢铁很硬并且不易碎，也具有耐高温的特点。而玻璃钢的发明解决了这一问题，现有的玻璃钢，其强度不足，易裂，耐高温性也较差。
发明内容

优选的，内衬层的内径为200~300mm，内衬层的厚度为20~40mm，糙率系数为0.0080-0.0082。
优选的，连接层内侧与外侧均涂布有粘度为0.5～0.8Pa·s的胶黏剂，所述胶黏剂由质量比为1:9的玻璃纤维与胶粘剂均匀混合而成。
与现有技术相比，本发明的有益效果是：
（1）本发明通过合理的选用阻燃剂，多次试验得出的配比方案，制造出成本相对较低的阻燃玻璃钢，在保证玻璃钢特性的同时，有效的防止了车体自燃的安全隐患，适用范围广阔，同时具备高强度，抗裂性能好，耐高温、抗腐蚀，经济环保的优点。
（2）内衬层中的邻苯二甲酸二丁脂是优良的增韧剂有良好的软化作用、稳定性耐挠曲性、黏结性、防水性等都优于一般的增韧剂；石墨粉的化学性特别敏感作为填充物具有很好的润滑性、可塑性、抗热震性并且具有很好的稳定新；滑石粉为触变剂能使配置物稠度增加；碳化硅微粉的作用主要是增加其硬度与耐磨程度；固化剂为乙二胺、聚酰胺、过氧化甲乙酮配比而成，固化剂是配方中特别重要的一个配方，使其固化效果更加稳定还具有防老化的作用；异辛酸钴为促进剂具有催干效果好。
