Description

一种透X光医用板材的制备方法、板材和应用
技术领域
本发明属于医用材料技术领域，具体涉及一种透X光医用板材的制备方法、板材和应用。
背景技术
X线是一种波长极短、能量很大的电磁波。X射线应用于医学诊断，主要依据X射线的穿透作用、差别吸收、感光作用和荧光作用。由于X射线穿过人体时，受到不同程度的吸收，如骨骼吸收的X射线量比肌肉吸收的量要多，那么通过人体后的X射线量就不一样，这样便携带了人体各部密度分布的信息，在荧光屏上或摄影胶片上引起的荧光作用或感光作用的强弱就有较大差别，因而在荧光屏上或摄影胶片上(经过显影、定影)将显示出不同密度的阴影。根据阴影浓淡的对比，结合临床表现、化验结果和病理诊断，即可判断人体某一部分是否正常。同时，X射线也是会对人体引起伤害的，因此需要控制X射线的辐射强度和频率，在保证成像效果的情况下，X射线的强度越低越好。
因此应用在X光检测设备中的床板必须满足如下要求：X线的高透过性，无毒无害及必要的机械强度。
现有技术中X线医疗床板多为碳纤维材料，生产工艺难度大，生产能耗高，且原材料贵，导致整体床板的成本居高不下。
发明内容
本发明提供了一种透X光医用板材及其制备方法和应用，用以解决目前的透X光医用板材成本较高的问题。
为了解决上述技术问题，本发明的技术方案是：所述透X光医用板材的制备方法，其包括如下步骤：
1)原纸制备：将原纸纸浆经酸洗后，造纸，纸卷表面进行在线空气等离子处理；
2)三聚氰胺浸渍纸：将步骤1)制备的原纸在三聚氰胺浸渍料中浸渍，浸渍比为1:(0.4-0.6)，烘干；
3)酚醛树脂浸渍纸：将步骤1)的原纸在酚醛树脂浸渍料中浸渍，浸渍比为1:(0.3-0.5)，烘干；
4)压合：将步骤3)制备的若干张酚醛树脂浸渍纸进行层叠，然后在上下表面分别层叠至少一张步骤2)制备的三聚氰胺浸渍纸，然后热压定型并进一步固化处理。
所述浸渍比是指原纸重量与浸渍料的重量比。
可选地，步骤1)酸洗是指原纸纸浆中加入1-3％的稀盐酸，然后加水清洗过滤。
原纸中残留的Cu、Al等会对X光进行吸收，清洗后可提高通过率，降低铝当量。
可选地，所述三聚氰胺浸渍料包括水溶性三聚氰胺-甲醛-尿素共缩聚胶黏剂和水溶性丙烯酸酯乳液，所述水溶性三聚氰胺-甲醛-尿素共缩聚胶黏剂和水溶性丙烯酸酯乳液按重量配比为10:(0.5-2)。
可选地，所述水溶性三聚氰胺-甲醛-尿素共缩聚胶黏剂和水溶性丙烯酸酯乳液按重量配比优选10:(1-1.2)。
可选地，所述酚醛树脂浸渍料包括环氧树脂和水，环氧树脂和水的重量比为(2～3):1。
可选地，控制每张三聚氰胺浸渍纸的厚度为0.48-0.52mm，控制每张酚醛树脂浸渍纸的厚度0.48-0.52mm，经步骤4)压合后，每张三聚氰胺浸渍纸的厚度为0.38-0.42mm，每张酚醛树脂浸渍纸的厚度热压后为0.38-0.42mm。
可选地，步骤4)中，中间酚醛树脂层是由11-16张酚醛树脂浸渍纸层叠形成，表面三聚氰胺层是由2-3张三聚氰胺浸渍纸层叠形成。
可选地，所述步骤3)中热压定型参数为，压力4-6Mpa、定型温度为170-180℃，热压时间为0.5-5min。
可选地，所述步骤3)中固化处理参数为，置于干球温度为140～150℃，相对湿度为90-95％的高温干燥环境中处理2-5小时。
充分的固化可以防止甲醛的释放，以满足生物安全性的要求。
本发明还提供一种透X光医用板材，其通过上述制备方法制备获得。
可选地，所述透X光医用板材总厚度为6.5-8mm，其中中间酚醛树脂层厚度为4.8-6.4mm。
酚醛树脂对X线的吸收少，也就是X线穿透性高，入射的X线强度就得到了有效控制，三聚氰胺层同样具有优异的X线穿透性，最后三聚氰胺及酚醛树脂之间粘结强度高，保证了必要的机械性能。
本发明还提供了一种转移床，其包括床架和设置在床架上的床板，所述床板的材料为上述透X光医用板材。
可选地，所述床架底部设有滚动机构。
通过上述转移床，病人躺在床上可以直接运送到检测室并直接进行透射扫描，无需将其移动到X光检测设备中的上，这样既减轻了医护人员搬运及清洁的难度，也避免了病人移动过程中的痛苦及风险。
本发明提供的技术方案采用三聚氰胺浸渍纸和酚醛树脂浸渍纸压合的复合板材替代了昂贵的可透X光的碳纤维板，通过工艺方法和参数的选择，获得了高透X光、低甲醛释放、机械强度符合医用板材要求的板材，由于其成本可控，使其可大面积用于转移床中，实现无移动X光检测。
具体实施方式
为了便于理解，下面结合实施例阐述所述一种透X光医用板材的制备方法、板材和应用，应理解，这些实施例仅用于说明本发明而不用于限制本发明的范围。
本发明所述转移床类似平时医院使用可移动病床，上面的床板可以根据需要采用整体一块，或者分成两块、三块或四块，床板都采用本发明提供的透X光医用板材，这样就实现了全床可透X的效果，多个床板时各个床板分别固定在床架上，相互独立，这样可以方便更换清洗和维护。
当然本发明提供的透X光医用板材也可以直接用于X光检测设备中。
