Description

FRP纤维增强复合材料筋的制备方法 技术领域
本发明涉及一种化工产品领域的中材料的加工工艺, 尤其是一种复合 纤维材料的加工成型工艺。 背景技术
传统的 FRP (纤维增强树脂)拉挤成型工艺由送纱、 浸胶、 预成型、 刮胶、 固化烘千、 成型、 成型烘干、 切割等工序组成, 一直以来, FRP拉 挤筋材都是以线性材料的形式出现, 同时由于其成型线性材料成型时使用 带状物拉紧成型, 固化后带状物与型材分离导致型材径向内应力不足, 造 成拉断后的截面均成径向放射拉断, 这使得所生产的 FRP拉挤筋材一经固 化定型后就很难弯曲成不同形状的筋箍, 导致在某些需要用到不同形状的 筋箍等场合中 FRP拉挤筋材的应用受到了极大的限制。
另外由于固化前空气中氧气等对型材表面基料的氧化作用, 使其固化 后型材表面有时会出现发粘的现象, 影响了材料的性能。 发明内容
本发明要解决的技术问题在于克服传统 FRP固化定型后很难弯曲成不 同形状的筋箍、 以及产品表面会发粘的缺陷。
为此本发明提供一种 FRP 纤维增强复合材料筋的制备方法, 包括送 纱、 浸胶、 预成型、 刮胶、 固化烘干、 成型、 成型烘干、 切割这几个工 序, 并且在预成型阶段内增加了横向纤维的缠绕; 在切割工序之前增加了 弯曲成型工序; 在固化烘干和 /或成型烘干工序中往供干环境中通入不易与 其它化学物质发生化学反应的气体。 。
所述烘干环节的加热方式可以是电加热、 波加热、 远红外加热或导 电油力 P热中的任意一种。
所述 FRP纤维增强复合材料筋可以是不饱和聚酯树脂或乙烯基树脂。 采用本发明所述的 FRP纤维增强复合材料筋的制备方法, 可以克服传 统 FRP 固化定型后很难弯曲成不同形状的筋箍的缺陷, 可以使得 FRP按 照人们的需要随意变换形状; 并且产品的表面干净, 不会发粘。
附图说明
附图 1所示为传统 FRP拉挤筋材的成型工艺流程图; 附图 2所示为本发明 FRP纤维增强复合材料筋的制备方法的流程图。 附图 3所示为本发明所 FRP纤维增强复合材料筋的制备方法中预成型 部分中口模的结构筒图。 具体实施方式
下面结合附图对本发明进行具体描述。
如图 1所示, 在传统的 FRP拉挤筋材的成型工艺中, 安装在纤维纱架 1上的纤维经过导纱器 2进入浸胶槽 3浸胶, 再经过集束器 4编织为一根 整体的纤维绳, 再经过预成型装置 5预成型, 之后进入加热固化装置 6中 进行固化定型, 然后经过牵引装置 7牵引至切割装置 8中切割为成品。
如图 2-3所示, 本发明 FRP纤维增强复合材料筋的制备方法, 在上述 传统 FRP拉挤筋材的成型工艺中, 对预成型部分进行了改造, 在预成型阶 段增加了横向纤维的缠绕。 在切割工序之前增加了弯曲成型工序。 横向纤 维的缠绕是由横向纤维缠绕装置完成的。 横向纤维缠绕装置包括电机 9、 齿轮传动装置 10、 转动架 11、 横向缠绕纤维纱架 12, 其中转动架 11为圆 环结构, 其上带有张力装置, 该张力装置用于为纤维提供张力。
FRP 纤维增强复合材料筋可以是不饱和聚酯树脂或乙烯基树脂, 下面 以不饱和聚酯树脂为例进行说明。 加工时, 安装在纤维纱架 1 上的不饱和 聚酯树脂纤维经过导纱器 2进入浸胶槽 3浸胶, 浸胶后的纤维通过转动架 11 上的张力装置获得一定的张力, 再经过集束器 4 集束进入口模 22, 通 过口模 22 的挤压使浸胶后的纤维密实形成带有螺紋的杆体, 然后通过预 成型装置 5上增设的横向纤维缠绕装置对带有螺紋的杆体作进一步的径向 缠绕, 以使螺紋得以定型。 螺纹结构给 FRP拉挤型材提供横向约束作用, 使预成型的筋材在未固化时具有一定的径向强度。
预成型后, 经过刮胶器 13、 烘干隧道 14至弯曲成型处, 在拉伸的状 态下弯曲成型。 弯曲成型工艺由弯曲成型机来完成, 弯曲成型机包括张力 装置 18、 成型模具 15、 带螺紋的导轨 17等。 成型模具 15为圆柱体状, 圆柱体中心有一螺距与导轨的螺距相同的螺纹孔, 成型时将预成型的 FRP 筋材在拉伸的状态下通过圆柱体模具上的压紧阀 16压紧, 在张力装置 18 的作用下模具开始旋转, 同时沿着带有螺紋的导轨作纵向的直线运动, 使 得 FRP 筋材弯曲成所需要的形状。 为防止张力过大导致预成型的筋材变 形, 成型模具 15的成型面可设计成带有螺旋沟槽的轨道。
在固化烘干的烘干隧道 14和成型烘干的烘房 19处, 增设气体导入孔 20 , 从外部通入不易与其它化学物质发生化学反应的气体 (如 N2、 C02 ) , 对型材进行保护, 消除氧气对型材表面基料的氧化作用, 避免固 化后 FRP型材表面被氧化、 从而导致发粘的结果。 此处的加热方式采用电 加热方式。 在其它实施例中, 加热方式可以是电加热、 ^敫波加热、 远红外 加热或导电油加热中的任意一种。
为解决 FRP拉挤筋材的弯曲问题, 本发明所述的 FRP拉挤筋材的弯 曲成型工艺不像传统的拉挤工艺那样在筋材预成型就进行固化定型, 而是 将预成型 FRP筋材经过刮胶器 13刮去 FRP筋材表面多余的树脂、 再经过 烘干隧道 14烘干后再经牽引机 7 牵引至弯曲成型机处进行弯曲成型。 该 成型机的口模 22 内表面带有螺紋, 其横截面为梅花形, 弯曲成型时为确 保 FRP筋材具有一定的纵向强度, 弯曲是在 FRP 筋材处于拉伸的状态下 通过模具的旋转和横向的直线运动来弯曲 FRP筋材的。 在其它实施例中, 口模的内截面形状可以是圆形、 方形、 菱形、 椭圆形、 多边形或梅花形中 的任意一种。
如附图 3所示, 口模 22通过六角螺母 24及定位销 23与背板 26连 接, 背板 26再通过螺栓与纤维缠绕装置的转动架 11连接。 预成型时纤维 束 21先浸胶, 浸胶之后经过导纱锥 25集束后进入口模 22, 通过口模 22 的挤压使浸胶后的纤维密实形成带有螺纹的杆体, 同时立即通过预成型装 置 5上增设的横向纤维缠绕装置对带有螺纹的杆体作进一步的径向缠绕以 使螺纹得以定型。
为解决 FRP拉挤筋材固化定型之后的径向内应力不足、 表面发粘的缺 陷, 并保证其在未经固化定型时不被压扁变形的情况下用牵引机进行牵 引, 该工艺在预成型阶段增加了横向纤雉的缠绕, 并对预成型模具进行了 预成型时口模的压挤使纤维密实形成带有螺紋的杆体的同时立即通过 纤维横向缠绕装置施加了一定预张力的纤维对预成型的杆体作横向缠绕, 使预成型的 FRP拉挤筋材中的纤维更加密实, 形成的螺纹得以定型, 对筋 材产生横向约束作用, 给 FRP筋材以一定的径向强度, 这不仅可使其在用 牵引机进行牵引时不至于发生变形, 杆体的径向尺寸特別是螺紋的螺距和 牙深的尺寸均一, 同时由于横向缠绕所用的纤维在此作为了一种永久的成 型材料, 使得 FRP筋材的力学性能如拉伸强度, 特别是扭矩大大提高。
为解决 FRP拉挤筋材的弯曲问题, 该工艺并不像传统的拉挤工艺那样 在筋材预成型就进行了固化定型, 而是将预成型 FRP筋材经过刮胶器刮去 多余的树脂、 烘干隧道后再经牵引机牵引至 FRP筋材弯曲成型机处进行弯 曲成型, 该成型机的模具内部带有螺紋, 弯曲成型时为确保 FRP筋材的纵 向强度, 弯曲是在 FRP筋材处于拉伸的状态下通过模具的旋转和横向的直 线运动来弯曲 FRP筋材。
